                                ABSTRACT
Current and proposed practices in animal  waste utilization and/or
disposal were reviewed by means of a detailed search of the litera-
ture, by correspondence and by visits with active investigators
in the field.

Abstracts were prepared of 1162 publications dealing with animal
waste utilization and/or disposal, or closely related materials
having a direct carry-over potential.  These latter publications
pertained to some other aspect of manure  management or to thermo-
chemical processing of some other organic material.  In addition,
abstracts of 111 pertinent projects sponsored by the USDA were
included in a separate appendix.

Land spreading, with or without advantage being taken of the
fertilizer and soil-conditioning values,  is the ultimate destiny
of nearly all manure produced at present.  Attention was focused
in the report, however, on the less-used  but potentially more
rewarding processes of gas or oil recovery, refeeding to animals
after more or less processing, and using  as a culture medium for
fly larvae, worms, algae, fungi, yeast, etc., with ultimate dis-
posal of the catabolized manure as a soil conditioner, and
utilization of the organisms as feedstuffs.

This report was submitted in fulfillment  of Contract No. 68-01-0785
under the sponsorship of the Office of Air and Water Programs,
Environmental Protection Agency.

                              CONCLUSIONS
The status of animal waste management is that of a maelstrom if
not that of an inferno.  Logic and delirium have both left their
imprint.  Fortunately, so also has the common sense which was
once believed to be implicit in a rural-based citizenry.

The premise that the produce of the soil should be returned in the
shortest feasible cycle to the soil has been often expressed and
more often implied.  And, unquestionably, land spreading of manure
is a nearly universal means of its utilization and/or disposal at
the present time.  There are, however, difficulties inherent in
the practice which may be expected to intensify and there are
opportunities of deriving values by other means of utilizing
manure which may lead to their adoptions under many circumstances.
TIME-RELATED FACTORS

Manure has fuel value comparable to that of lignite or oil  shale.
To date, only a few small installations using the methane produced
in anaerobic digestion have attracted investment in competition
with nower supplies based on fossil fuels.  The situation is
changing dramatically; for large concentrations of manure,  in
appropriate climatic settings, conversion to oil or gas may soon
be the most rewarding utilization.

Manure contains proteins, amino acids, and other nutrients  which
can be concentrated by various processes for direct refeeding to
animals or for feeding to insects, algae or bacteria which  may,
in turn, become a component of feed.  With continued research
and further population pressures such practices may be expected
to increase.

It can be anticipated that the shifting urban-rural interface will
continue to absorb land which would otherwise be available  for
manure spreading.  Moreover, the specialization of agri-business
with greater concentrations of animals and separation of meat-
producing and feed-producing functions may be expected to persist.
these trends, in turn, require negotiations for spreading areas
and involve longer hauls.

The intensified concern for controlling pollution has rendered
obsolete many a practice tolerated quite recently.  Odors and
the possibilities of contamination of streams and groundwater
are subject to regulations which will have profound effects on
the choice of manure management program.

                                   1

-------
PLACE-RELATED FACTORS

For most operating conditions -- as distinguished from the total
question of site optimization which includes nearness to markets,
feed, and labor -- an ideal  climate is one with a high evaporation
potential and no sub-freezing temperatures.   Artificial  drying of
manure is expensive; the charges for it, routinely inserted in
balance sheets for thermochemical  processing drawn up in humid
settings, have contributed heavily to the adverse benefit-to-cost
ratios reported.

Precipitation and drainage patterns should be considered carefully
in planning for land disposal of manure, in that polluted runoff
should be prevented from reaching streams or groundwater.  Drainage
of the supernatant, after detention in a settling pond,  by gentle
slopes to playa lakes whose bottoms have become sealed over geologic
time would appear to be ideal, particularly if the runoff can be
pumped for irrigation.

The density and type of surrounding develonment are related to the
level of odor nuisance tolerable from a livestock or poultry
installation and thus can influence, to a marked degree, the choice
of manure utilization system.
SCALE EFFECTS

To be viable a capital-intensive installation must be large.   This
principle is exemplified in the hundred-thousand head feedlots and
million-bird poultry operations of recent years.  It may limit the
applicability of thermochemical processing to areas which contain
concentrations of such installations.

                             RECOMMENDATIONS


To provide intelligent planning and guidance of manure disposal
practice in the years of change foreseen as being on the immediate
horizon it will be necessary to encourage research on a broad
spectrum of problems.  Those of highest priority are seen as being:

     1.  To conduct pilot-plant studies on a number of thermo-
chemical processes for extracting oil and/or gas from the manure of
beef cattle feedlots.  Such plants should be in a semi-arid setting
with a high evaporation-minus-precipitation value, near large
concentrations of cattle on feed, in an area having existing natural
gas and other petroleum developments, and having convenient sites
(preferably with internal drainage) for fail-safe natural drying of
manure.  In such areas one would find expertise in cattle and
petrochemical problems, a steady market for the oil or gas produced
which would absorb the fluctuations in pilot-plant operation
serenely, and a broadly-based regional self-interest in making a
success of the venture.

     2.  To intensify studies on the refeeding of derivatives of
manure and on the catabolism of manure by protein-rich larvae.
Much expertise, but little funding, for this exists in the Agricul-
tural Research Service of the USDA and on many campuses at present.

     3.  To provide for continued monitoring of developments in
the field of animal waste utilization and/or disposal  in order to
make available as promptly as possible indications of significant  .
trends.  This should include the coverage of periodicals (both
scholarly and trade) in many fields; the abstracting of reports of
governmental, research, and other organizations; and the inauguration
and maintenance of contacts with other workers in the field on a
world-wide basis.  To be most effective, such a program should be
established at a university which has a productive record in research
in many disciplines bearing directly on the problems of animal wastes,

                              INTRODUCTION


From an airplane window Denver and Albuquerque appear to be por-
tions of a single city with a virtually continuous grid of streets
clearly visible.  Further development of the megalopolis is, of
course, limited to a few nodes at present.

Such "improvements," however, certainly put agriculture on notice
that there will be little tolerance of odors by the future occu-
pants or by the land developers who can allege in court that the
potential value of their holdings was reduced by such nuisance.
The implications for manure handling and utilization are many and
far-reaching.
                    PREVIOUS STATE-OF-THE-ART SURVEYS

With very few exceptions the predominant utilization (or disposal)
of manure involves its spreading on land with some advantage being
taken of its fertilizer value and/or its soil conditioning value.
The early literature (of which only a few samples are abstracted in
Appendix A) dealt almost exclusively with analysis of fertilizer
values of manure and litter from various sources applied to specific
crops grown in specific soils under specific climatic conditions.

As the problems of intensified concentrations of animals on feed
and of encroaching suburbia became apparent, students of the prob-
lem investigated other possibilities.  On balance, however, and with
more or less reluctance, most of them concluded that land spreading
was the optimum destiny of manure.

BLACK [1967-1002]*, in seeking solutions pertinent to Ontario,
weighed the merits of composting, anaerobic digestion, aerobic
treatment, and lagooning.  He concluded that despite the diffi-
culties involved when livestock and crop producers are distinct,
and with the crop producer able to use commercial  fertilizers at
less cost than "free" manure, "... the application of manure  to
soils is well  justified and desired."

-------
LOEHR [1968-1027, 1969-1045], in a we11-documented penetrating
survey of the state of the art of manure utilization, observed
that little study had been given to any aspects of the age-old
practice of land disposal other than crop response.   He accorded
detailed consideration to a number of alternatives to land
disposal -- anaerobic digestion, aerobic treatment,  anaerobic
lagoons, anaerobic-aerobic systems, incineration and drying, and
miscellaneous processes which, "because of technical or economic
difficulties, .  . . have not found wide application."

WADLEIGH [1968-1042], in a frequently cited study of the disposal
of the wastes from agriculture and forestry, observed that the
cost of transportation of manure frequently exceeds  its value as
fertilizer and advocated the study of the possibilities of utiliz-
ing manure as a culture medium for the propagation of organisms
antagonistic to known plant pests and diseases.  He  also recommen-
ded the combination of agricultural and industrial wastes as an
effective soil amendment.

JONES [1969-1039], sneaking at the first of the annual  conferences
on agricultural  waste management at Cornell University, discussed
the by-then usual list of alternatives and predicted that the
future would include greater urban sprawl  and more rural non-farm
residences.  "Man-made" land renovated by sludge disposal and con-
tracted manure handling services were considered to  be possibilities,

MOORE [1969-1061] classified the management of manure into four
distinct steps:   collection, storage, treatment, and utilization
or disposal.  This latter was primarily to the land.  MOORE and
8ROOKER [1970-1071], looking into the future, predicted that
improved rations can be expected to produce a richer manure which
may be refed or may become a source of nutrients, antibiotics, and
vitamins.   Lagoons may well be replaced by digesters with these
latter being warmed by burning the gas they generate.  They foresaw
the raising of livestock in complete confinement with no runoff,
and anticinated rural zoning separating town and feedshcd with
several  miles of cropland, partly irrigated with animal wastes.

DALE [1971-1064] surveyed a number of means of waste disposal and
concluded that,  at least until the size of operation increases,
return to the soil "appears to be the more feasible  way to handle
dairy cattle wastes." 'YECK and SCHLEUSENER [1971-1272], in a
oaper presented at the same symposium, observed that land recycling
was the current best nractice.  They then discussed  sixteen alter-
natives  which could well prove to be preferable when operations are
large, land is scarce, or neighbors are fastidious.

The Canada Committee on Agricultural Engineering issued a guide
[1972-1022] designed "to bring together the current  practices that
provide  reasonable approaches to handling animal wastes."  Land
recycling  was emphasized.

                                  6

-------
GOLUEKE  [1972-1053,  1054] evaluated  ponding and  its refinements,
digestion, composting,  land disposal,  refeeding, pyrolysis, and
assorted fermentations  under the  felicitous title, "Changing from
Dumping  to Recycling."  HODGETTS  [1972-1069], in surveying American
waste disposal practices for a British readership, observed that
"land spreading is still, of course, generally the cheanest, most
efficient and most popular means  of  disposing of animal manures,
but the  economic cost of doing this  may in some cases be so high
as to make the system unattractive."  He was particular.lv intrigued
by the research in the  catabolism of manure by fly larvae and the
subsequent feeding of the protein-rich larvae, pupae, or adult
flies to chickens.

SHUYLER  [1973-1030]  saw the high-priority research needs in the
animal feedlot program  as being "1)  the need to develop techniques
for reprocessing and converting animal wastes into a usable
product. . .  [and] 2) the urgent  need to make the current information
on animal waste management readily available for widespread use by
governmental  agencies,  the feeding industry, and researchers in the
field. . ."   The processes he considered to be currently promising
include  conversion to some type of fuel, feed or additive for animals,
or other by-product.  The present investigation, nearing its final
phase when SHUYLER's study appeared, reached the same conclusions
independently.
SOLID WASTE STUDIES

Animal wastes have usually been considered to some extent in gen-
eral surveys of solid waste disposal.  However, manure is more
uniform and tractable, and the nuisance created by it becomes of
direct personal concern to far fewer people.  Thus, its handling
problems tend to be glossed over in these general  studies.   There
is, however, much of transfer value in the discussion of methods
tried or proposed for the management of municipal  refuse, and a
perusal of the well-documented studies of GOLUEKE  and McGAUHEY
[1970-1029, 1030; 1971-1106; 1972-1106] and of the series of solid
waste bibliographies by CONNOLLY and STAINBACK [1971-1059;  1972-
1024 through 1027] can be rewarding.
PREVIOUS BIBLIOGRAPHIES

MINER has prepared a brief discussion of the literature on animal
wastes for each previous year as a portion of the annual litera-
ture review of the Journal of the Water Pollution Control
Federation each year since 1963 (review of 1967).  In addition,
he prepared bibliographies for Iowa State University [1972-1111]

references.
               ORGANIZATION AND OBJECTIVES OF THIS REPORT

A study of the management of animal wastes, as mentioned earlier,
would involve consideration of four operations:  collection, storage,
treatment, and utilization or disposal.  Any effort to optimize an
operation will., of course, require that attention be given to all
four components.  It was not the objective of this report, however,
to prepare a self-contained treatise on animal waste management.
On the contrary, the purpose here has been to provide a guide to
facilitate research into the utilization and/or disposal of manure.
Thus, in the interests of brevity, no organized discussion of the
collection or storage of manure has been prepared and methods of
treatment are considered in some detail only because they are often
so intimately associated with utilization or disposal that no
indisputable boundary could be established.  This lacuna is filled
to some extent by the abstracts.
LAND SPREADING

As mentioned earlier in this chanter, the predominant method of
utilization and/or disposal of animal wastes is by land spreading.
The previous state-of-the-art reports cited treat the subject
comprehensively as do many specialized papers listed under "Land
Spreading" in the index to be abstracts.

The deficiencies in research referred to by LOEHR [1968-1027] are
being remedied.  In particular, studies of optimum and of maximum
non-damaging application rates of manure to land are reported in
many of the recent papers abstracted.  In view of the abundance of
readily-available treatments of the subject, no detailed discussion
of it will be offered here.

-------
OTHER METHODS OF UTILIZATION AND/OR DISPOSAL OF MANURE

The other methods of utilization and/or disposal of manure have
been classified in this report as microbiological, macrobiological,
and thermochemical and discussed in chapters IV, V, and VI,
respectively.  The microbiological processes are frequently treatment
methods rather than means of ultimate disposition.
                      ENVIRONMENTAL CONSIDERATIONS

The economic  incentive  for  seeking alternatives to land, spreading
is to be found  in  long  hauls,  reouirements of storage between
periods when  spreading  is feasible, senarate ownership of feedlots
and croplands,  competition  from  artificial fertilizers, and risks
of saline  or  other damage to some crops  in some circumstances.  In
addition,  land  spreading and some of  the other methods of disposal,
as well, involve  potential  pollution  of  air, water, and/or soil.
References to a large number of  papers discussing various aspects
of environmental  quality may be  found under the headings:  Air
Pollution, Odor Control, Fly Control, Groundwater Pollution, Runoff,
Nitrates in Soil,  Salt, Pathogens, and Toxicity in the index to the
abstracts  [Appendix D].

                             DRYING OF MANURE

An all-pervasive  topic  in manure management is the moisture content
of the  manure.   It affects  both  the pollution potential and the
cost  of handling.

Water,  recycled or from some other source,  is often added to manure
to facilitate its handling  as  a  slurry  [see abstracts cited under
"Liquid Manure  Handling"  in the  index, Appendix D].  This practice
introduces a  secondary  problem in  that an  additional volume of
material will have become  polluted and should be  used, or otherwise
disposed of,  without risking contamination  of surface streams or
groundwater.

 Dewatering, a rather loosely defined  term  used  here to designate
mechanical means  of separating liquids  from solids, has  been
accomplished  by vacuum filtration  [CASSELL  et al,  1966-1013], by
 electro-osmosis [CROSS, 1966-1017;  NURNBERGER et  al, 1966-1056]
 by centrifugation [ROSS et  al, 1971-1219;  SENIOR,  1973-1029,  1043],
 and  by use of a screw press [MENEAR  and  SMITH,  1973-1023].   MENEAR
 and  SMITH, using manure from dairy cattle,  found  the crude  protein
 content of the liquid portion  (on a  dry  basis)  to be 49.6  percent.
 SENIOR'S process  is reported to recover  315 Ib  of protein  per net
 ton  of manure.   Of this, about 240 Ib are obtained from the liquid
 portion and the balance is available from the  fibers  retained by
 the  centrifuge.

-------
The disposal of poultry manure is facilitated by drying in that
the drier manure is more convenient to handle, is less odiferous,
and occupies less volume.  RILEY [1968-1033] describes eight makes
of heat dryers for poultry manure available on the British market.

SURBROQK et al [1970-1092, 1971-1238] report the price per ton of
manure, dry basis, for a commercially-produced, on-the-farm dryer
for poultry, bovine, and swine wastes.  SHANNON and BROWN [1969-
1077] tabulate the losses in energy and in nitrogen content which
result from the drying of poultry manure by various procedures.
THY6ESON et al [1971-1249, 1250] reported on experiments in which
superheated steam was used to dry pelletized manure.

BRESSLER [1969-1012; 1970-1010; 1971-1035, 1036, 1149; 1972-C012]  -.
has perfected a two-stage drying operation in which the moisture
content of poultry wastes is reduced from 75 percent to 30 percent
by stirring in the poultry house and from 30 percent to nine percent
in a commercial dryer.  The final weight is one-third of the
original.  Costs are stated to be less than $4 per ton.

MAYES [1972-C067] states that the cost of dehydration is about
equal to the wholesale selling price of dehydrated manure.  Despite
the dust and odor associated with dehydration, he finds that it
may 6ften: be the preferred solution.  BER6DOLL[1972-1014] estimated
drying costs to be about six to eight dollars per ton of dried
product.  Total costs, including transportation to the dryer, would
be about $15 to $35.  PRICE [1972-1127] stated the cost range for
drying to be about $6 to $7 for European conditions, and valued
dried poultry waste at $18 per ton as poultry feed, and somewhat
higher as :feed for ruminants.

The drying of manure by evaporation occurs at a rate substantially
less than that from a free water surface.  In arid and semi-arid
climatest however, natural drying may permit the safe use of
simplified methods of manure management [WELLS et al, 1971-1258].
Moreover, the effects on costs are such that conclusions reached
using values for humid regions may be inapplicable elsewhere.
This line of thought will be pursued further in the discussion of
costs of thermochemical processes (Chapter VI).

                        MICROBIOLOGICAL PROCESSES


The treatment of human sewage is accomplished by processes which
are predominantly microbiological.  What, then,'would be more
reasonable than to apply the same procedures, with appropriate
modifications, to animal wastes?  Pursuing this line of thought
we risk treading the path of the prophets of doom with their
astronomical figures for population equivalents in the calcula-
tion of livestock wastes and their exhortations that salvation
for mankind on earth lies in the soybean.

Fortunately, manure isn't sewage.  As has often been pointed out,
the oneisavery dilute suspension of solids in water while the
other is a slurry which may be diluted for convenience of handling
but only with acceptance of the penalty of having a larger polluted
mass to dispose of.  There are some valid parallels, however.
Manure in its undiluted state is somewhat similar to sewage sludge
and responds similarly to anaerobic treatment -- with, unfortunately,
risk of odor production.  Diluted and aerated, it can be stored
for more timely spreading.  The details are best developed in con-
junction with a review of the literature.
                           ANAEROBIC TREATMENT

The bacteria capable of decomposing organic substances anaerobically
are found universally in nature, particularly in decaying matter.
In the decomposition they produce methane and other gases and a
stabilized sludge with a fertilizer value nearly equal to that of
the original material.

[1946-1001, 1951-1001,  1952-TooTTattest to the activity in the
application of microbially-produced methane for on-premise power
production in France and Algeria in the post-war years.   Some 500
to 600 small plants existed in France and FERAUD observed that the
nation's manure contained a potential thirty trillion calories of
energy.  For comparison, the total  French energy production in
1938 was 230 trillion calories.

WINTERS [1957-1002] reported on the powering of a farm in South
Africa with methane.  He found pig manure to be twice as productive
as cattle manure.  FREY [1961-1006] described a power plant he
built in South Africa in 1958 in which the methane released from the

                                  11

-------
1600 Ib of dung produced daily by 700 pigs yielded sufficient
electricity to power the farm and three houses free of all  fuel
costs.  Cooling water pipes conveyed waste heat from the engine
through the digester.

HUTCHINSON [1962-1006] operated a coffee plantation in Kenya on
methane.  Ten years' land application of the residue, as his sole
fertilizer, doubled his coffee yield.

Other indications of interest [1961-1009, 1967-1018] appeared in
the 1960's but ALLRED [1966-1002] observed that methane utilization
had ceased,in northern Europe.

PFEFFER [1971-1206] studied the potential for energy reclamation
from solid wastes under an EPA grant during 1969-1972.  LAURA and
IDNANI [1971-1148] tested the efficacy of various additives to
manure to increase the methane production.  They found urine and
dried leaves to be effective.

COSTIGANE et al [1972-1029], in an intensive investigation into
the theory and feasibility of anaerobic digestion, concluded that
the most economical and efficient design for methane production and
waste stabilization "is not at present considered feasible for
animal waste treatment on a small farm due to the high initial
equipment cost."  They recommended, however, that further investi-
gation be pursued toward reducing the initial capital cost and they
proposed also that financial analyses be made for a farm community
and for cattle feedlots of various sizes.  Based on this study,
P. L. SILVESTON and J. M. SCHARER of the University of Waterloo
submitted a research proposal to Environment Canada in November
1972 for funding a prototype plant for a family farm of about
100 dairy cattle.

SAVERY and CRUZAN [1972-1135] conducted tests on an experimental
anaerobic digester for the production of methane gas from chicken
manure.  Their calculations indicated that a 60,000-chicken unit
would supnly enough methane to be self-sufficient in its total
electricity reauirement, but at a cost six times that of its
nresent supply.  They considered that improved technology and the
then-impending shortage of natural gas should reduce the adverse
cost-to-benefit ratio.

A somewhat similar, but economically more attractive, study by
HALLI6AN and SWEAZY [1972-1060] will be discussed in Chapter VI.
ANAEROBIC DIGESTION

Anaerobic digesters, as we have seen, produce methane.  They also
produce an easily dewatered free-flowing liquid sludge with a.soupy


                                 12

-------
texture, inoffensive odor, and essentially undlmim'shed fertilizer
value.  TAIGANIDES et al [1963-1012], in an assessment of sludge
digestion, cited these advantages and also mentioned a reduction
(by 50 to 75 percent) in organic content of the waste, a stabili-
zation preparing the residue for ultimate disposal in a lagoon or
on land, and a lack of attractiveness for flies and rodents.  Their
list of disadvantages include a high capital cost, the necessities
of sludge disposal and of daily supervision, and the possibility
of explosions.  HART [1963-1007] considered digesters to be a
feasible and desirable means for treating chicken manure at a
reasonable cost.

GOLUEKE [1971-1106] observed that little volume reduction results
from anaerobic digestion.  GRAMMS et al [1971-1110] have proposed
ultimate disposal of the sludge by land spreading, composting, or
burning.  KLEIN [1972-1079], working on the problems of solid
waste disposal, recommended that anaerobic digestion be employed
only for the reduction of putrescible organic wastes -- including
manure.
ANAEROBIC LAGOONS

DORNBUSH [1970-1018], reporting that properly designed anaerobic
lagoons will control odors and stabilize wastes, described the
mechanism of' the treatment as involving two stages.  In the first
stage the organic matter undergoes breakdown with little reduction
in BOD or COD; in the second, methane and COg are released and the
waste stabilizes.  The effluent, however, will require further
treatment.  Design criteria are empirical and highly temperature-
sensitive.

Unless loadings are kept low, or other precautions are taken, farm
lagoons will be anaerobic.  An anonymous study [1963-1014] cautioned
that aeration is futile since an acre of water surface would accomo-
date only 1200 chickens or 50 hogs while remaining aerobic.  The
combination of an anaerobic lagoon with the supernatant flowing to
an aerobic lagoon was considered to be excellent.

CURTIS [1966-1018] and WILLRICH [1966-1076], basing their recommen-
dations on studies in South Dakota and Iowa, proposed design criteria
for anaerobic lagoons.  LOEHR [1967-1012, 1968-1026] observed that
anaerobic lagoons are essentially septic tanks and proposed design
criteria for them.  The MIDWEST PLAN SERVICE [1969-1055] issued a
two-page guide for their design and operation.

PFEFFER [1970-1076] described the mechanism of their operation as
consisting of an acid fermentation followed by a methane fermen-
tation, and likened it to that of the bovine rumen.
                                   13

-------
PARSONS et al [1970-1075] proposed design specifications for a
poultry lagoon, suggesting that it would be prudent to construct
one only in a rural area tolerant of odors.  WHITE [1970-1106]
found that state regulations were usually vague on the subject
and that descriptions in the literature were often incomplete and
failed to employ a standard set of parameters.

FEE [1971-1087] and KOELLIKER et al [1972-1082] describe the
anaerobic lagoon in use at Iowa State University for an 800-head
hog finishing unit.  Water from the lagoon is recirculated for
flushing, and the excess is employed for irrigation.  In nine years
of operation no lagoon cleaning had been required.

HAZEN [1971-1125] found that an anaerobic lagoon with 3.5 to 5 Ib
of volatile solids per 1000 cu ft provided satisfactory preliminary
treatment for hog wastes.  SHINDALA and SCARBROUGH [1972-1141],
disposing of hog wastes in Mississippi, recommended that the lagoons
be regarded as being only the first step in treatment.  BARTH [1972-
1011, 1973-1002], based on laboratory investigations in South
Carolina, found them to be "dependable, low-cost, and successful."

SMITH [1972-C089], studying infiltration rates in anaerobic lagoons
treating swine wastes in Georgia, observed a decrease from two feet
per day in 1969 to a half foot per day at the end of 1971.

NANSON [1972-C078] is studying strains of bacteria capable of
growth using methane as their sole carbon and energy source.  He
is also seeking useful products obtainable from methane.
                            AEROBIC TREATMENT

Secondary treatment of sewage is aerobic.  Thus a wide variety of
aerobic processes came readily  perhans too readily -- to mind
when sanitary engineers first gave serious thought to the pollution
potential of manure.
CONVENTIONAL SEWAGE TREATMENT

PELLET and JONES [1946-1003] reported that, with the extension of
piped water to rural areas in Britain, consideration was given to
reducing the potential- pollution of cowshed washdowns by including
them in the inflow to sewage treatment plants.  KEEN [1969-1040]
observed that discharges of animal wastes to sewers had been quite
common in the United kingdom until an Act of Parliament in 1961
permitted cities to assess charges and refuse loads.  Discharge
to streams being forbidden, this imposed serious burdens on some
farmers.  The position taken by the responsible authorities [1969-
1091] was that waste disposal must be regarded as a production cost.

-------
Spokesmen for the farmers' union  [1969-1090, '1971-1108] adv&cated
provision for the disposal, at least of  sunernatant,  to sewers.
They pointed out that land spreading in  a damp climate leads tp
runoff to streams and that reliance on it results  in  delays due
to mud and freezing.  Anaerobic stabilization was  rujjb cprt$idered
to be a viable alternative.  SIDWICK [T972-1I42] cfeiljdrkd;jt!ie slug
loads, often including straw, which reach Sewage:b^atififentrplants'
in Britain from cattle markets.

JAWORSKI and MICKEY  [1962-1007],  discussing America^  pradtice in
cage washing, reported that water for all but the  final rinse is
recycled.  When the  final rinse water, drawn from  potable mains,
drains to the recycling  tanks an  equivalent volume is released to
the sewer.  MacDONALD and DAVIS [1966-1045] observed  that fixed
zoos tend to use municipal sewers and they tabulated;  BOD measure-
ment for various animals at New Orleans.  Prfmates, ^h'ich'nave been
used for studies of  human diseases pose  critical prdhFf&ns/  'FRlTSCHI
and MacDONALD [1971-1096] renorted that  the BOD of w.astes from
primates was three to six times as high  as that frditii  ^fnans;'.  Heavy
chlorination is employed at sewage treatment plants;h4ftdling their
wastes.

JOHNSON  [1965-1013,  1014, 1015] proposed modified  septic tanks
(anaerobic) for treatment of manure from dairy cattle and poultry.
Methane generated would  be burned to heat the digesters and flushing
water would be reused.   He described a pilot plant serving a 7000-
bird operation in Massachusetts.                      ;

DUCK WASTES

Ducks pose serious pollution  problems because of the relatively
large volumes of water  employed  in  raising  them and the potency
of their wastes.  HOVENDEN  [1970-1038],  discussing this: latter point,
chose for title, "Coliformally Speaking,  Ducks StirtL'!.. GATES [1963-
1005] described procedures  instituted on  Long Island where  duck
farms were polluting  shellfish and  recreational areas.; The use  of


                                   15

-------
water per duck was cut to ten gpd from a previous 25 to 75,
sedimentation ponds were installed, and chlorination was begun.
Sludge disposal from the sediment traps is difficult to schedule
and supervise.

DAVIS et al [1966-1020] reported the adoption of two sediment basins,
used alternately, below a duck farm in Virginia.  This solution
reduced coliforms by 90 to 95 percent and permitted the resumption
of oyster harvesting downstream.

LOEHR and SCHULTE [1970-1053; 1971-1222, C060] proposed a five-day
retention in an aerated lagoon of the slug flows of duck manure
washed into the water by precipitation.  An additional settling pond
and final chlorination were also called for.  Cost reduction was
seen as being attainable only through reducing the water usage.
AEROBIC LAGOONS

JONES, DAY, and DALE [1972-1075] have prepared a comprehensive,
readable, and well-documented up-to-date study on aerobic treatment
of livestock wastes.  In it they reviewed the theory of aerobic
treatment, discussed oxidation ditches at some length, and set out
design criteria for oxidation ponds and for mechanically-aerated
lagoons.  They recommend that ultimate disposal be by irrigation.

The use of indoor lagoons under poultry has been the subject of a
number of papers.  Al-TIMIMI et al [1964-1001, 1965-1001] reported
that neither heat, air, nor any combination of them was effective
in reducing the solids content in such lagoons.  They recommended
a volume of 3.5 cu ft per bird as being adequate with biennial
cleaning.  HOWES [1968-1023] reported a fifty percent reduction
in bulk in a pit inoculated with aerobic bacteria.  He had dis-
turbed the surface cake weekly in winter and twice weekly in summer.
The resulting sludge was an odorless fertilizer usable in urban
gardens.  CASES et"al [1969-1016] and BARR et al [1970-1128]
reported that an indoor poultry lagoon at Louisiana State University
was proving to be effective.  The lagoon effluent flowed, by means
of an open ditch, fifteen hundred feet to a fish-inhabited bayou.
Both fish and hens were doing well.  VICKERS and 6ENETELLI [1969-
1082], praising oxidation tanks for the odorless fly-free effluent
they can produce with a minimum of maintenance and operation,
advocated separating the liquids and solids and then applying them
to the land.'  C.  H."THOMAS [1972-C097] reported that in four years
operation an aerated lagoon under poultry in Louisiana had accumu-
lated seven Ib of solids per hen per year with no odor problems
resulting.

DALE [1968-1012]  observed that aeration can almost eliminate odor
from dairy cattle wastes, but mentioned that degradation is slow.


                                   16

-------
BERRY [1966-1008] recommended that aerobic lagoons in cold climates
be agitated, supplied with oxygen, diluted, and heated.  NYE et al
[1971-1189] stated that oxygen must be supplied to accomplish the
aerobic decomposition of dairy cattle manure.  The reduction in COD
was better at high temperatures.  PRATT [1972-C081] found that a
lagoon in Fargo would remain aerobic except in winter.  BARTH and
POUQWSKI [1971-1020] suggested that only the surface layer of
lagoons be aerated over the winter.  Such a practice reduces
operating costs, improves nutrient recovery, and allows the reuse
of the supernatant for flushing.

BLOODGOOD and ROBINSON [1969-1010] observed that aerobic storage
before land spreading minimizes odor problems.  OGILVIE and DALE
[1971-1190] noted that aeration for less than 24 hours may be
effective in rendering manure relatively odorless.  They suggested,
however, that an additional aerated lagoon be added in areas sub-
ject to freezing.

DALE et al [1969-1023, 1971-1063] floated a guyed aerator in the
center of a pond and irrigated cropland with the effluent at a
maximum solids content of two to three percent.  They reported
the system to be odorless, inexpensive, and universally applicable.
It saves nutrients, minimizes runoff, lowers potential pollution,
and requires little labor.  GILLILAND [1970-1028] cited cost data
for a similar installation.  TEN HAVE [1971-1247] observed that
surface aerators with vertical shafts have less trouble with bear-
ings than do oxidation ditch rotors and for this reason aerated
ponds are replacing oxidation ditches in current Dutch practice.
OXIDATION DITCHES

Oxidation ditches have been discussed so exhaustively in the
literature that it seemed pointless to add yet another analysis
of their behavior here.  Thus, with the exception of the subtopic
of refeeding of oxidation ditch residue to animals, which is treated
in Chapter V, the subject is being dismissed with the suggestion
that reference be made to the index to the abstracts and to JONES,
DAY, and DALE [1972-1075] for information on them.
         COMBINED OR SEQUENTIAL ANAEROBIC AND AEROBIC TREATMENT

Most bacteria are neither strict aerobes nor strict anaerobes;
thev are facultative.  Moreover, ponds tend to stratify with the
oxvqen content decreasing with depth.  Thus waste stabilization
is" often facultative in fact and occurs in ponds in which the
boundary between aerobic and anaerobic portions shifts with the
seasons.
                                   17

-------
As was observed by JEFFREY et al [1965-1012], aerobic lagoons as a
sole treatment dejvice are economic only if the feeder happens to
possess a large pond.  (The Canada Animal Waste Management Guide
[1972-1012] cites the surface requirement as 19 acres for 1000 hogs,
mentions that 15 million [imperial] gallons of water would be
required for initial filling, and adds that "it is also doubtful
whether the relatively small volume of manure added would maintain
a satisfactory;liquid depth in:the lagoon.")  A series of ponds,
with the firstione being anaerobic, was pronosed as being a nromis-
ing alternative1,

For the handling of manure from beef cattle feedlots AGNEW and
LOEHR  [1966-1001; 1967-1014, 1026; 1969-1047] advocated the combi-
nation of an anaerobic lagoon located in the vicinity of the feedlot
followed by an aerobic lagoon for the treatment of the effluent.
If the liquid is to be released to streams it would be prudent to
add a  second aerobic lagoon for final polishing.  The cost of the
series of two Qf ;three lagoons may be moderate since the operator
often  possessed the excavating machinery reouired.  The digested
solids may be' Handled by pumping for land spreading at appropriate
times, and the effluent may often find application for irrigation
or other non-potable uses.

Successful applications of lagoons in series have been described
[1969-1008, 1013, 1021; 1971-1186] as was an interesting variation
[1971-1312,] consisting of an anaerobic lagoon with thirty-day
detention time for the treatment of hog wastes followed by an
oxidation ditch which produces an effluent claimed to be "cleaner
than most; industrial or municipal wastes."  The ditch effluent is
discharged to |he Fraser River, one of British Columbia's most
productive salmon streams.

BARRETT p97HOT;3] advocated a two-pond system in which "settled
liquor 
-------
PALMER [1964-1013], reporting on a seven-paper ASAE Symposium,
stated that "all the speakers agreed that lagoons, as a means of
ultimate manure disposal, had been overrated and under-built."
CLARK [1965-1006], in a report of his investigations of lagoons
for hog wastes in Illinois, observed that "never were the complaints
found to be unjustified.1" HART and TURNER [1965-1011] emphasized
the dangers of infiltration and the nuisance of odors.  OSTRANDER
[1965-1018] added the frustrations of freezing.

PONTIN_and BAXTER [1968-1032], concerned primarily with British
conditions, advocated pretreatment of manure prior to land-spreading
and discussed the relative merits of digesters, oxidation ditches,
and lagoons.  HART [1970-1032], reflecting the improvements which
resulted from the investigations of the 1960's, concluded that
"lagoons and oxidation ditches are not magic wands, but they can
be very reasonable manure processing-units."  This appears to be
a fair summary of their current status.
                               COMPOSTING

The principles and history of composting have been summarized in
two very readable papers by GQLUEKE [1972-1054, 1055].  While the
process can be either aerobic or anaerobic and in either the
mesophilic or thermophilic temoerature ranges, modern preference
tends to be aerobic to mitigate odor nuisances and to be thermo-
philic to enhance the probability of killing pathogens and weed
seeds.  Moreover, these choices of operating conditions speed the
composting process.  Aeration, moisture content, temperature,
carbon-to-nitrogen ratio, and particle size are the principal  para-
meters governing the process.

HART and SCHLEUSENER [1963-1008], in summarizing an ASAE symposium,
observed that while manure is too moist for successful composting
and garbage is too dry, too low in nutrient, and too bulky,  a
proper mixture may prove to be ideal.  BELL [1971-1024] added the
caution that trash and salt should be avoided in combining municipal
and agricultural wastes for composting.  WILEY [1963-1013] proposed
the addition of sawdust to compost poultry wastes effectively.
GALLER and DAVEY [1971-1098, 1099] reported that such compost makes
a good soil conditioner.

HARTMAN [1963-1009] recommended composting of poultry manure as an
economical means of fly control.  He suggested semi-annual nit
cleaning leaving a six-inch layer of manure.  LIVSHUTZ [1964-1011]
gave cost data for the composting of poultry manure employing forced
aeration of windrows covered with plastic sheets to prevent top
drying by sun and wind and wetting by rain and snow.  EASTWOOD et al
[1967-1005] reported that twice-weekly turning of windrowed poultry
manure compost'eliminated flies.  Fully-composted manure is
unattractive to flies.

                                   19

-------
WELLS et al [1969-1086] found composting to be an effective method
of handling wastes from the beef cattle feedlots of the High Plains
of Texas.  While large numbers of fly larvae appeared during the
first week, they were killed by the heat generated in a weekly
turning program.  The material stabilized sufficiently rapidly to
be vermin-free in less than ten days.  GRUB [1971-1117] observed
that skilled management is required to obtain satisfactory results
in the composting of beef cattle feedlot wastes.

BELL and POS [1971-1026, 1027] reported indifferent success with
the composting of ooultry manure in Guelph, Ontario.  They were,
however, able to operate throughout the winter.

WILLSON and HUMMELL [1971-1265, 1972-1168] deduced a set of rules
for the optimum composting of dairy cattle manure.  SCHULZE [1972-
1194] developed methods for continuous composting and presented
cost data.

HOWES [1966-1037] observed that poultry litter can be renovated
by proper composting in place.  Such practice would be useful  after
floods or after diseased birds.  PATRICK [1967-1019] and SMITH
[1967-1021] advocated the comnosting of litter to destroy
microorganisms.  HANKS [1967-1006] questioned the effectiveness of
operational, as contrasted to laboratory, composting in the
elimination of pathogens and PETERSON [1971-1205] expressed concern
over the potential hazard of a residual pathogen content.

YEATMAN  [1970-1108] reported that the Pennsylvania mushroom crop
of 125 million Ib utilizes 400,000 tons of compost per year.  The
spent compost is still a good soil conditioner.  SINKEVICH [1973-
1031] added that the preferred compost is made from horse manure
from local racetracks or even, in winter, by shipment from
New Orleans to Pennsylvania.  An acceptable substitute can,
however, be made from chicken manure.
                              FERMENTATIONS

GOLUEKE [1972-1054] summarized the potential of assorted fermentations
as follows:

          "A variety of fermentations and biological hydro-
          lysis systems have been developed for breaking
          down cellulose to its constituent glucose units.
          The glucose is used as a substrate for the pro-
          duction of yeasts which can be incorporated into
          livestock feedstuffs.  These processes are largely
          in the research stage.  At present, the economics
          of the processes are highly unfavorable."
                                   20

-------
SINGH and ANTHONY [1968-1034] separated manure from concentrate-fed
steers into solubles and fiber.  The solubles, which on a dry basis
constituted 68.57 percent of the manure, were inoculated with yeast,
incubated, and dried.  The crude protein content of the resulting
yeast product was 40.9 percent  (dry basis).  The mineral content
was too high, however, to permit its effective use as a feed.  MOORE
and ANTHONY [1970-1070] by adjusting the nH of fermenting cattle
manure daily for three days with ammonia raised the crude protein
level from 16.99 to 43.26 percent and increased the amino acids by
over 20 percent.  ANTHONY et al [1973-1001], reporting on the
results of fermenting mixtures of cattle manure with forages or
hulls, observed that the mixture will have high nutritive value
only if it is maintained at a pH near 4.  Further investigations
are underway [1972-C003].

HELLER [1969-1054], in a 173-page study devoted primarily to the
conversion of municipal wastes, waste paper, and bagasse by
fermentation, placed the cost of the process "at best at the high
end of the current high protein supplement price range."  KEHR
[1970-1042] stated that a two-stage hydrolysis-fermentation process
holds promise.  Further study would be required to obtain cost
estimates.

JACKSON et al [1970-1040] attempted to circumvent the toxicity of
uric acid for poultry by fermenting poultry manure before refeeding
it.  HAMILTON et al [1971-1118] experimented with fermentation as a
means of improving the quality of manure as a feed.

CALLIGHAN and DUNLAP [1971-1046] converted bagasse to bacterial
single-cell protein by fermentation and reported the preliminary
economic data to be encouraging.  THAYER [1971-1282, 1288] "has
shown that feedlot wastes can be used both as a cellulose and a
nitrogen source for conversion of it and other waste into a complete
cattle feed with a single cell protein base."  What cannot be
converted is used as roughage.  SWEETEN [1973-1042] observed that
fermented mixtures of fresh feedlot manure and roughage improve  the
rate of gain and feed efficiencies of beef cattle.

CREGAR et al [1973-1008] ensiled broiler litter based on pine
shavings to produce an effective pathogen-free cattle feed with
negligible drug carryover.  HARMON et al [1973-1012] tested
ensilages of various proportions of broiler litter with corn forage
at two different states of maturity.

WALDROUP [1973-1038] established that, with proper precautions,
yeast may constitute 20 percent of a chick's ration.  Algae,
however, is perhaps preferable.  LaSALLE and LAUNDER [1969-1042]
proposed to ferment chicken manure in a weak phosphoric acid solu-
tion maintained in catch troughs, to extract the proteins and carbo-
hydrates for feedstuffs, and to use the residue for fertilizer.
Thev estimated the gross profit of the operation to be $14.50 per ton,

aspects of manure fermentation under USDA sponsorship.
                        GENERAL ELECTRIC'S STUDIES

In October 1971, Feedstuffs announced, crediting as its source of
information Pfizer Feeder Facts, that an unnamed concern from out-
side the field of agri-business was reported to be about to erect a
pilot plant ;in the Southwest in which thermophilic microorganisms
would convert cellulose and lignin to microbial protein which could
be used as animal feed.  In April 1972, Feedstuffs [1972-1202]
announced that the pilot plant would open in the summer of 1972
after years :of preliminary research.  The May issue of Feedlot
Management [1972-1196] carried a mock-up and a flow diagram of the
plant plus a column of explanation of the process.  In October,
Beef [1972-1184], CALF News [1972-1100], and the Water Resources
Newsletter [jl972-1224] announced the opening of a nilot plant in
Casa Grande, Arizona, in which the wastes from 100 head of cattle
would be digested by thermophilic bacteria to produce a cellular
mass, high ijn protein, which would be dried then used as a feed
supplement for cattle.  The results of FDA studies of the project
were expected by mid-1973.  MANTHEY, writing in Feedlot Management
for October [1972-1100] gave the most extensive account which has
come to the writers' attention.  After observing that "the recla-
mation system provides a bonus in that it turns out to be a protein
multiplier -;- it harvests 1-1/2 Ib of protein for every pound
that is fed Jinto it in the form of animal wastes," MANTHEY quotes
rather extensively from various officials of General  Electric
associated with the project.  The November Issue of Environment
News [1972-1 jl92] reported that 120 Ib of feed were being produced
daily from the 340 Ib (dry basis) of manure supplied.

Inquiries in: Phoenix in May, 1973, led to the information that the
pilot plant had been placed on a standby basis while further work
was being rushed at the laboratory.  The thermophilic bacteria,
it appears, had not adjusted satisfactorily to pilot-plant scale
operation.  A paper was presented orally on the process at a
meeting of the AIChE in June, 1973, but copies had not been made
available when this report was written several weeks later.


                      THE HAMILTON STANDARD PROCESS

Several of the papers cited on the General Electric project also
mentioned a somewhat similar study being pursued by the Hamilton
Standard Division of United Aircraft Corporation.  In the Hamilton
Standard process [1973-1045, 1048], manure is slurried, heated and
fed continuously to a fermentation tank in which anaerobic bacteria

operating in the thermophilic temperature range convert it to
methane, carbon dioxide, and a solid residue which can be dried and
used as an ingredient of feed.  Alternatively, the residue may be
coated with resin and pressed into board or used as a nutrient for
a fungus that produces a fiber-digesting enzyme which may be used to
improve the digestibility of poultry feed.  For an ooeration in-
volving 5000 to 7000 or more head of cattle, the methane produced
from the wastes would be sufficient to provide all the heat and
power required for operation.

TURK [1972-C099], in a progress report on an ARS-sponsored study
of the process stated that

          "cattle feedlot waste at 10% solids concentration
          can be digested in continuous anaerobic fermenta-
          tion at feed rates between 0.5 and 1.0 pounds of
          volatile solids per cubic foot digester per day
          with a residence time of 6.25 davs.  The optimum
          temperature is 49-51C.  A 40-60% reduction of
          solids occurs with 90-95% of carbon in the input
          accounted for in the gas + output solids.  No sig-
          nificant loss of nitrogen occurs in the gas.
          Methane production is 3-4 cubic feet per pound
          volatile solids introduced.  The gas is consistent-
          ly 50-52% methane; the remainder is CQ2-  Hydrogen
          is not produced. . .  Digestion and gas production
          have been consistent for 9 months of continuous
          operation."
                  OTHER MICROBIOLOGICAL INVESTIGATIONS

ANDREWS and KAMBHU  [1971-1012], after completing a theoretical
analysis of the steady-state operation of thermophilic anaerobic
digestion of organic wastes, suggested its application to the
disposition of sludge resulting from the treatment of sewage.
containing ground garbage.  Their 76-page report, with its' 55
references, contains much of interest for manure disposal.

CARLSON [1971-1051], in describing the Babson Biochemical Recycle
Process, reported that it separates cattle wastes into soueeze-
dried solids of a quality usable as bedding and roughage and a
liquid which may be "processed to any degree of purity desired by
ion-exchange and charcoal treatment, and also ultra-violet exposure
if potable water is desired."

Enzyme-facilitated microbial decomposition of cattle feedlot manure
was discussed by ELMUND et al [1971-1084].  A brief note in Poultry .
Digest [1973-1051] reported that a fiber-digesting enzyme produced
from a fungus grown on cattle feedlot waste had improved the feed
efficiency of chicks.  It is reasonable to anticipate that much more
will be heard of this development in the future.

                        MACROBIOLOGICAL PROCESSES
The quantity of manure which will be recycled in the foreseeable
future by being employed as a planned constituent of the feed of
animals, birds, fish, insects, or worms is probably quite small.
That which will be deliberately released to ponds to become nutrients
for water hyacinth, algae, yeast, or other vegetation will  doubt-
less be even less.  Use as fertilizer in which the manure,  decom-
posed by the microlife of the soil, is recycled as crops or weeds
may be expected to continue to be the major employment of manure.
In the longer run, however, particularly if the trend toward
concentrated production of animals -- and manure -- in a suburban
environment intensifies, the recycling of manure as a feed component,
its catabolism, and its botanical conversion hold much promise.
                           REFEEDING OF MANURE

One's initial reaction to the concepts of refeeding manure to
animals or of employing it as a medium for the deliberate production
of fly larvae is apt to be revulsion.  Visions
epidemics are readily conjured.  There are, in

DIETARY AND GROWTH FACTORS

One may easily appreciate that some nutritional value may remain
in particles of feed which have been passed through a first
digestive tract unutilized and essentially unaltered.  There are,
moreover, other values.  A spate of papers in the 1940's reported
the existence of "an unidentified growth factor,"  riboflavin
(vitamin 82), and/or vitamin 812 in the feces of poultry and animals.
LAMOREUX and SCHUMACHER [1940-1002] established that more riboflavin
was present in poultry feces than in poultry feed, with the increase
occurring after defecation.  KENNARD et al [1948-1003] found the
riboflavin in freshly-voided chicken feces to be essentially that
of the feed, but observed a build-up at room temperature of 100
percent in 24 hours and 300 percent in a week.  Floor litter may
thus serve as a potent source of supplementary vitamins for chickens.

HAMMOND [1942-1002] observed that a cow's rumen content was higher
in vitamins than was her feed.  Still greater concentration of
vitamins occurred in the feces.  Cow manure was found to have a
beneficial effect when fed to riboflavin-deficient chicks and to
cause no harm when fed to others.  Later [1944-1002], in recommendina

-------
the inclusion of cow manure in wartime poultry diets, he advised
supplementing the diet with vitamin A and riboflavin.

RUBIN and BIRD [1946-1004, 1947-1002] determined that the growth
factor present in cow manure is transmitted by hens in their eggs
in a quantity sufficient to permit their chicks to grow well on a
basal diet.  RUBIN et al [1946-1005] reported 25 percent greater
weight at six weeks for chicks with a five percent supplement of
cow manure or urine-free hen feces in their diet.  ELAM et al
[1954-1001] reported increased chick growth resulting from the
inclusion of a filtered suspension of autoclaved old poultry
litter in the ration.  Litter contributes far more to the growth
of chicks than can be accounted for by its protein content alone.

BIRD et al [1948-1001] reported that young turkeys have a critical
need for a growth factor found in cow manure, fish meal, or meat
meal.  BOHSTEDT et al [1943-1002] had observed earlier that cow
manure supplies B-complex vitamins to pigs.

BIRD et al [1946-1002] established that increased hatchability of
eggs resulted when a soybean meal diet was supplemented by cattle
manure.  GROSCHKE et al [1947-1001] observed that the addition of
cow manure to a corn-soybean oil diet for chickens increased hatch-
ability and removed its seasonal fluctuation, this latter being
credited [1948-1002] to coprophagy inasmuch as dietary factors are
more easily synthesized in hen feces in warm weather.  KENNARD et al
[1954-1003] determined that hatchability and chicken health were
both far better when chickens were raised on old litter than on new,
the difference again being credited to the benefits of coprophagy.

Vitamin content of manure has been shown to vary with its age and
treatment.  RUBIN and BIRD [1947-1003] observed that sun-dried or
oven-dried cow manures were essentially equivalent, but that
pasture-dried chips were inferior in poultry diets.
COPROPHAGY

Later, studies with rats by BARNES et al [1959-1001, 1963-1002]
and DAFT et al [1963-1003] established that coprophagy was essential
to their development.  Nine micronutrients supplied to rats from
their own feces were listed.  Rabbits were reported by EDEN
[1940-1001] to consume from 54 to 82 percent of their total fecal
production.  SOUTHERN [1940-1003] suggested that this trait might
well  account for the ability of wild rabbits to subsist during
several  days of cold or danger without other nurishment.  DURHAM
et al  [1966-1025] reported on coprophagy in ruminants on all-
concentrate diets, observing that in extreme cases postmortem
examinations had found the reticulum and abomasum compacted with
heavy deposits of soil and feces.


                                  26

ANIMAL MANURE IN POULTRY RATIONS

In addition to the papers already cited, one by RILEY and HAMMOND
[1942-1003] observed that the development of testes and ovaries in
chicks was retarded when dried cow feces were included in the diet,
but that their development was unaffected when the chicks were fed
feces from mature bulls.  WHITSON et al [1946-1006] reported that
cow manure dried at 80C is preferable to that dried at 45C since
the latter impairs egg production while the former does not.
Hatchability was good on either ration component.  TURNER [1947-1004]
observed that the performance of cockerels fed manure from lactatinq
cows fell off when the manure exceeded 10 percent of the ration,
while pullets responded well to 2.5, 5, 10, or 20 percent.  PALAFOX
and ROSENBERG [1951-1002, 1952-1003] found that 5 or 10 percent of
either oven-dried (below 158F) or sun-dried cow manure, when
substituted for mash, satisfactorily supported egg production, egg
weight,  body weight, hatchability, and feed consumption.  At 15
percent, unresolved conflicting results are reported.

HAMMOND  [1944-1001] fed cow manure (fresh, and dried and 47C,
80C, and 120C) to poults as ten percent of their diet as a
substitute for alfalfa leaf meal on an essentially adequate ration.
Liyability, growth rate, and efficiency of feed utilization were
unimpaired.  He considered drying at the highest temperatures to
be preferable since bacteria are destroyed without impairing
nutritional values.  SLINGER et al [1949-1003] reported a supple-
ment of  five percent dried cow manure to be effective when fed to
turkeys  in a soybean-oil meal ration.

LIPSTEIN and BORNSTEIN [1971-1154] reported that dried cow manure
had no toxic effect when fed to chicks, but concluded that it was
a poor substitution even for inert pulverized rock.  It may be
significant that they reported a 36.4 percent ash content in their
dried manure.
ANTHONY'S STUDIES  IN  RECYCLING CATTLE MANURE

The  "pork value" of cattle manure -- the nutritional value salvaged
on the old-time farm  by  the pigs which followed the cattle -- has
become a casualty  of  modern agri-business.  One is tempted to suggest
that when an elderly  environmentalist fondly recalls the pristine
succulence  of  grandma's  roast, the  ingredient he misses may well be
cattle feces.  In  fact,  however, taste tests are rarely accurate
in diagnosing  this component of a pig's bill of fare.

In the only menu abstracted [1972-1009], the piece of resistance was
a Delmonico steak  from a yearling steer fed an ensiled mixture con-
taining corn (48 percent), hay (12  percent), and waste (40 percent).
The menu, appropriately  entitled "A Phase of Research in Livestock

                                   27

-------
Feeding," was that of a banquet served at Auburn University, site
of Brady ANTHONY'S amazing string of successes in feeding cattle
manure to cattle.

The earliest of ANTHONY'S papers which has come to the compiler's
attention [ANTHONY and NIX, 1962-1001] describes a feeding trial
in which a mixture of forty percent washed cattle feces and sixty
percent basal feed, to which one Ib of yeast per 100 Ib of mixture
had been added, was fed to three cattle for 54 days.  Gains of
3.39 Ib/day on 6.43 Ib of feed (dry basis) per Ib of gain were
reported.  ANTHONY has subsequently modified the formula several
times, but the insistence on the use of fresh manure from a concrete
lot, with fermentation, and with controlled handling and storage
of the resulting mixture has been retained.  The exclusion of mud
and the preservation of freshness appear to be cornerstones of
successful refeeding.  Two notes in the Farm Journal [1963-1010
and 1015] and one in Compost Science [1964-1024] reported ANTHONY'S
findings, stressing the $8000 cost of a "washing machine" to handle
a 2000-steer operation.

Reporting on his experimentation of the next several years,
ANTHONY [1966-1005] observed that either washing or heat treatment
was desirable; an attempt to use fresh, unwashed manure separated
by screening had produced poor weight gains and been reflected in
lower carcass grades.  Later, trials with an ensiled mixture of
57 parts manure and 43 parts coastal bermuda grass blended with
ground shelled corn and a supplement had given excellent results.

When "waste!age" (a name assigned to the ensiled mixture of 57
percent manure from full-fed slaughter cattle and 43 percent ground
hay) was employed as 40 percent of the ration, gains were better
than those posted by a control group of cattle fed corn silage
[1968-1003, 1969-1002, 1972-1217].  In describing his experimental
program at the Cornell Conference on Animal Waste Management
[1969-1003], ANTHONY emphasized the sanitary disposal of organic
wastes and the improved feed efficiency obtained.

BANDEL and ANTHONY [1969-1005] reported that a ratio of wastelage
to*   whole corn of 2:3 is nearly optimum for slaughter cattle.
CIORDA and ANTHONY [1969-1020] observed that even with nematode
eggs present in the feces, no larvae were found in any sample of
wastelage examined.  ANTHONY [1970-1003] reported that "rations
containing wet cattle manure were readily consumed by fattening
steers and these rations supported gain essentially equal to com-
parable cattle fed feeds without manure.  Cooking or washing
manure before mixing it with concentrate for feeding did not improve
its feeding value.  Carcass data were similar for manure-fed and
other cattle."  MOORE and ANTHONY [1970-1070] reported an increase
in crude protein level of wastelage from 16.99 percent to 43.26
percent by adjusting the pH level with ammonia on three successive
days.   The ami no acids were increased by over 20 percent.

                                  28

-------
Three more waste!age tests were reported  [1971-1014] and a flow sheet
for the recycling of manure from concentrate-pius-wastelage-fed
confined cattle was presented indicating  that the disposition of the
feedlot manure would be complete if the surplus wastelage were used
as a complete ration for beef brood cows.  ANTHONY'S well-documented
summary of the state of the art of animal refeeding [1971-1013]
should be read in its entirety.  An extract from it will be quoted
in the summary of this chapter.

Currently ANTHONY is focusing his attention on lactic acid fermen-
tation in the ensiling process [1972-C003] and on the optimum
choice of material (silage, green chopped forage, cottonseed hulls,
peanut hulls, rice hulls, almond hulls, etc.) for blending with the
manure [1973-1001].  All hull mixtures were found to be less satis-
factory than mixtures made with silages or green chopped rye forage.
"To be acceptable products should be fermentable. . .  The mixtures
used must ferment rapidly to produce acids (preferably lactic) and
the pH must be about four.  Most important:  When fed, silages must
retain an acid pH; if the pH shifts rapidly toward neutrality when
placed in the feed trough, the product will have low nutritive
value."
OTHER  FEEDING OF  RUMINANT  FECES TO  RUMINANTS

ANTHONY  [1967-1001]  reported that ewes on a diet consisting solely
of wastelage for  more  than  a year consumed less hay but remained
in better physical condition than those fed hay with no manure.
McLAREN  and BRITTON  [1968-1030] observed that when lambs were fed
a high-energy diet with  roughage consisting of ground corn cobs,
wheat  straw, or the  undigested fiber fraction of their feces at the
same level as the original  roughage, the percentage of roughage
digested was greater for the original corn cobs or wheat straw than
for the  refed fecal  fiber.

L. W.  SMITH et al [1969-1078, 1970-1086, 1971-1229, 1971-1230,
1971-1301] reported  successful experiments in the modification of
cell walls in cattle feces  to improve their digestibility for
subsequent refeeding to  sheep.  SMITH and GORDON [1971-1231] reported
feeding  iso-nitrogeneous rations with one part cornmeal and one,
two, or  three parts  manure  consisting of feces and peanut hull
bedding  to heifers.  There  were no  significant differences in growth
rate or  in feed-to-gain  ratios.

THOMAS et al [1970]  reported that heifers fed feces from dairy
cattle without bedding accepted a ten to fifty percent fecal diet
readily.  The dry matter digestibility was 20 percent.  CALF News
[1970-1117] quoted Gene  ERWIN as stating that "It is entirely
feasible that even a small  feeder will be able to process manure
on his lot for conversion  into a low-cost nutritious feed."


                                  29

-------
BUCHOLTZ et al [1971-1040] stated that feces must contain more than
25 percent crude protein to compete economically with other sources
of supplemental nitrogen.  In their feeding tests sheep had consumed
all rations readily while goats had refused to participate in any
fecal recycling.  McCLURE et al [1971-1167, 1329] reported decreasing
digestibilities in corn-based rations for cattle, rations for sheep
containing 45 percent cattle feces, and the feces from the sheep.

COOPER et al [1972-1028] reported that a ration of an ensiled
mixture of whole corn plant and feces from ewes on an all-roughage
diet was not highly acceptable to ewes.  Additional corn and soybean
meal produced a ration adequate for maintenance when the fecal
fraction was held below 25 percent.  JOHNSON [1972-1074, 1216]
found rations consisting of cotton seed hulls and up to 40 percent
dried feedlot manure palatable to sheep.  The digestible organic
matter content of the wastes from dirt lots was low.  KLOSTERMAN
and McCLURE [1972-C051] reported on a 60-day feeding test in which
the weight of steers had been sustained on a diet consisting solely
of ensiled feedlot manure.

TINNIMIT et al  [1972-1157] reported that sheep rations containing
20 to 80 percent dehydrated feces were well accepted.

SWEETEN [1973-1035, 1042] questioned the economy of the prompt
collection and of the exclusion of mud from cattle feedlot manure
which would be required for the preservation of its refeeding values.
These are, of course, high in the list of advantages claimed for
totally-enclosed confinement feeding.

In addition to the "classical" well-documented studies, such as
those of ANTHONY, there are an indeterminate number of other
investigations of means of salvaging the nutrient value of manure
in progress or in various stages of hibernation or death.  Some of
these have been referred to in the chapter on microbiological
processes.

Many investigators are understandably reluctant to talk until they
have obtained satisfactory results in feeding tests.  Questions of
possible patentable features in a process or the desire to derive
a legitimate financial reward for the time and money risked in
research and development also inspire a cloak of secrecy.

An interesting example of such a project, nearing the pupation stage,
is that developed by Feed Recycle, Inc., of Blythe, California, its
consulting engineer Frank SENIOR and his associate Dr. Ralph  RIPPERE.
A description of the process appeared in CALF News for January 1973
[1973-1043], and an evaluation of the economics is abstracted in
[1973-1029].  SENIOR, a consulting metallurgical engineer of Phoenix,
was retained by the corporation, the major stockholders of which
include the owners of Mortensen's Colorado River Feedyard, Blythe,

                                   30

-------
and those of the Desert Ginning Co. of Ripley, California, to
perfect a process for extracting the proteins, fats, and roughage
values of feedlot steer manure for refeeding.  The sand, salts, and
most of the moisture are removed in the process.

The pilot plant, visited on 10 May 1973, had evolved somewhat from
the status described in CALF News.  The molasses produced in the
earlier operation had not proved to be effective as a component
of the feed.  On the other hand, the "instant coffee" granules
resulting from the kiln-drying of the cake separated by centrifuging
had given most encouraging results in feedinq trials.  The 8000
Ib/hr input to the pilot plant had consisted"of 660 Ib protein,
160 Ib fat, 1980 Ib carbohydrates, 240 Ib K and NaCl, 440 Ib Si02,
520 Ib of other insolubles, and 4000 Ib of water.  In a second stage
5600 Ib of washwater and floe had been added.  The values recovered
per net ton of manure, based on 315 Ib of protein at 14 
-------
up to 65 percent PAB without rejection.  BRIDGSON [1972-1020, 1179]
reported that cattle on a 37.25 percent PAB ration consumed more
feed and gained weight faster than control cattle.

VETTER et al [1972-1160, 1225] reported feeding beef oxidation ditch
residue, which they designated "processed animal waste nutrients"
(PAWN), in amounts as great as 6.8 kg/day per steer without observ-
able effects on carcass grade, yield, or health.
FEEDING OF CATTLE FECES TO SWINE

Despite the historic tradition previously mentioned, few tests of
the value of cattle feces in swine rations have been recorded.
SQUIBB and SALAZAR [1951-1003], reporting on the feeding of sun-
dried fresh cow manure subjected to a hammer mill, observed that
despite the fact that pigs ate the rations readily and consumed as
much feed as did pigs on Corozo palm nut meal, sesame oil meal,
bananas, or animal protein factor, the lots fed cow manure were
unthrifty and lacked uniformity.  PUTNAM [1971-1211] reported that
the Agricultural Research Service (ARS) had fed beef feedlot manure,
subject to various treatments, in amounts up to 85 percent of the
rations of swine successfully at Beltsville.
RECYCLING SWINE FECES

DIGGS et al [1965-1007] reported that in a 63-day trial with the
rations containing 0, 15, and 30 percent dried pig feces, pigs
gained 1.56, 1.71, and 1.53 Ib/day respectively.  Feed intakes were
3.63, 3.62, and 4.65 Ib/day.  No undesirable flavor was detectable.

ORR et al [1971-1193, 1194, 1317] reported that corn-soybean meal
rations with as much as 22 percent dried swine feces were accepted
by swine with 90 to 95 percent full appetite.  The flavor of the meat
was unaffected.  Dried swine feces containing 21.6 percent crude
protein were detrimental to daily gain and to feed-to-gain ratios
because of low ami no acid content.  MILLER [1972-C070] reported that
swine wastes were preferable to poultry wastes in swine finishing
rations.
SHINE OXIDATION DITCH RESIDUE

DAY et al [1971-1066] reported that pigs on oxidation ditch
residue (ODR), substituted ad tlbJJiw for water in the ration,
showed greater weight gains and better feed efficiency.  HARMON
et al [1971-1120] observed that swine ODR, screened to remove hair
and bran then freeze-dried, contained 41.5 percent protein.  Rats
showed best weight gain and greatest feed efficiencies when their

                                  32

-------
ration contained zero to four percent ODR.  HOLMES et al [1971-1135]
found a crude protein content of 27.7 percent, dry basis, for the
suspended solids in swine ODR, and concluded that it could be sub-
stituted for 10 to 20 percent of the other proteins in rats'  diets.

HARMON [1972-C043] concluded that concentrations significantly
higher than the two percent dry matter typical of swine ODR will  be
required.  For an oxidation ditch in continuous operation for three
years, the dry matter tested 51 percent protein, 1.4 percent lysine,
2.0 percent threonine, 0.9 percent methionine, and 40 percent ash.
HARMON et al [1972-1062] reported that swine ODR had a 27.7 percent
protein content and that it could replace from a third to half of
the protein in casein or soybean meal for rats.
POULTRY MANURE IN ANIMAL FEEDS

Poultry manure tends to be richer in nutrients than animal manure.
Moreover, layers are fed few antibiotics and thus the worrisome
problems of drug and hormone residues may be minimized by the
selection of caged layer manure as a feed component.

VERBEEK [1960-1005] observed that a ration containing 24 percent
fowl manure with mealie cobs provided a good sourde of nitrogen
for oxen.  Other nutrients and spilled feed in the wastes added
value.  The manure made a good addition to roughage for tiding
oxen over a winter.

Several authors have reported feeding tests in which poultry wastes
replaced soybean meal or other sources of protein with essentially
equivalent daily weight gains [1966-1064, 1968-1007, 1970-1096,
1972-1146, 1973-1009].  BUCHOLTZ et al [1971-1039, 1040], however,
reported lower feed efficiencies on dried poultry wastes (DPW) than
on soybean meal or urea, and observed that the manure should contain
more than 25 percent crude protein to compete economically with
other sources of supplemental nitrogen.  They mentioned that steers
sorted out and avoided the DPW, sheep consumed all servings readily,
and goats refused the ration.

LOWMAN and KNIGHT [1970-1054] estimated the cost of the protein from
DPW to be about one-third that from competing sources.  In other
economic studies, LOWMAN [1969-1049, 1092, 1094; 1970-1130] states
that Topi an, a sterile DPW with a crude protein content of 26.6
percent available on the British market, when fed as 25 to 50
percent of a ruminant ration saves 30 percent on feed costs.  BULL
and REID [1971-1041] observed that air-dried poultry manure was
particularly effective with corn silage since the combination
eliminates dust, masks odor, and saves $12 to $15 per ton.
                                   33

THOMAS et al [1972-1155] reported that economic studies indicate
the desirability of using relatively large amounts of dried manure
from caged layers as nitrogen and energy sources for cows and lambs.
SMITH and FRIES [1973-1034] observed that, despite reduced milk  ,
output from cattle fed DPW, the economics of feeding it compare
favorably with those of conventional sources of crude protein.
FAIRBAIRN [1970-1135] stated that the protein value of DPW is about
that of cereals, but that the energy content is only about one-third
that of grain.  He concluded, however, that DPW is suitable and
economic as a feed component.

COUCH [1972-1030] observed that the low energy content of DPW makes
it unadvisable as a component of chick feeds above five percent.
The age of the manure at the time of drying and the method of drying
were recognized to affect the energy content critically.  Swine
were reported to show depressed feed conversion with as little as
five percent DPW.  Sheen can obtain up to fifty percent of their
total nitrogen from it without adverse effects.  The best use of
DPW is considered to be as cattle feed.  NATZ [1972-1117] also
observed that DPW has been recommended as a cattle feed.

PEREZ-ALEMAN et al [1971-1204] fed DPW as 10, 20, and 30 percent
of a swine ration with no adverse effect on the pigs' health or
carcass quality.  They reported that DPW contained 30 percent
crude protein and was rich in minerals.  ORR [1971-1193] reported
that DPW was of somewhat less value than dried swine feces in swine
rations because it is low in critical amino acids and high in
calcium.

THOMAS and ZINDEL [1971-1248, 1972-C110] reported no adverse effect
on the quantity or quality of milk from dairy cows fed 30 percent
DPW.

LOWMAN and KNIGHT [1970-1054] observed that, whereas barley contains
48 ppm Cu and DPW contains 73, the copper available to sheep fed
barley or DPW was 24.5 and 17.6 ppm respectively.  SMITH et al
[1973-1033] observed that "withdrawal of arsenic from feed resulted
in a rapid decrease in tissue arsenic concentration."
POULTRY MANURE IN POULTRY FEED

The benefits which poultry derive from the reingestion of their
feces in terms of growth, increased hatchability, and general
well-being have been discussed.  Additional studies in a similar
vein include those of PRYOR and CONNOR [1964-1015] who reported
that 30 percent of the original metabolizable energy present in c
high-energy chicken ration was available for reuse.  FLEGAL and
ZINDEL [1970-1022, 1023, 1024; 1971-1090], in studies directed
toward compensating for the low energy content of DPW, found


                                  34

-------
that the addition of stabilized fat improved performance of layers
on a diet which included 20 percent DPW.  The egg-laying efficiency
was unaffected to 20 percent DPW; the taste difference of the eggs
was undetectable to 30 percent; and the egg quality was unaffected
at 40 percent.  Feed efficiency declined with increasing propor-
tions of DPW in the ration.

BIELY et al [1972-1018, 1973-1050], reporting on feeding tests of
well-balanced isonitrogenous isocaloric rations containing 5 to 30
percent DPW, found no detrimental effects on the heaHh of the birds
Growth and feed efficiency decreased above 10 percent.  BER6DOLL
[1972-1014] suggested that the optimum refeeding level for laying
hens is in the range of 10 to 15 percent DPW, with the manure
replacing an equal amount of corn.

The feeding value of manure, it must be remembered, is subject to
rapid deterioration with improper storage or mishandling.  MILLER
[1971-1173] observed that poultry manure catabolized by fly larvae
had little value as chick feed.

HODGETTS [1971-1133] reported that a flock of British chickens
showed improved performance on a 10 percent DPW diet.  Savings
resulting from the refeeding were 44 cents per bird.  ZINDEL and
FLEGAL [1971-1275] evaluated DPW as a replacement for 25 percent
of the corn in a layer ration at $10 per ton.  For comparison,
they calculated the gross value of wet manure as a fertilizer to
be $2.39 per ton; the cost of spreading it would be $11.96.

LaSALLE and LAUNDER [1969-1042] reported on a proposal of the
Hupsi Corporation to catch chicken droppings in troughs of weak
phosphoric acid, then salvage the protein and other values for
refeeding.  By refrigerating the acid during the cycle, air
conditioning could be provided in the hen house.

A fascinating study, designed to provide a definitive answer to
some of the haunting questions of possible cumulative effects of
refeeding, is being conducted at Michigan State University.
ZINDEL [1972-1170, 1204] reported that after 35 cycles in which
DPW was refed as 12.5 or 25 percent of the hens' ration, no build-
up of heavy metals had occurred.  He concluded that these percen-
tages could be recycled with safety.  FLEGAL et al [1972-1045,
1190], reporting after 31 cycles, observed that the chickens on
12.5 DPW were outperforming those fed 0 or 25 percent.  FLEGAL
[1972-C032] also reported that performance on recycling was as
good with 10 or 20 percent DPW as with none.  Performance was
poorer at 30 percent, and egg production was off 40 percent at
40 percent DPW.  Interim reports by various investigators have
been abstracted [1971-1089; 1972-1159, 1208, C110; and 1973-1052].
                                   35

LANGSTON [1971-1318] reported on a 36-hour process of heating to
kill pathogens followed by fermentation and refeeding of the
manure to the same chickens.   No ill  effects were observed.
CLIZER [1972-1006] has emphasized the establishment of proper
controls for attaining uniformity of product.   He and BARTON
[1972-C005] both stressed research to secure compliance with
FDA requirements.

Lest the reader gain the impression that poultry manure recycling
is a complete solution to ultimate disposal, he should heed  the
sobering comment of OUSTERHOUT and PRESSER [1971-1200] that
"recycling manure reduces the disposal problem by no more than
25 percent with no noticeable further reduction with further
recycling."  NESHEIM [1972-1118] added that while acceptability
of manure is good, chickens compensate for its low energy content
by eating more and, thus, producing more manure.
POULTRY LITTER IN ANIMAL FEED

Poultry manure has been described through the use of many adjectives.
All of them have repulsive connotations of sliminess, stickiness,
and stench.  By comparison, poultry litter is relatively
unobjectionable.  The litter base of sawdust, wood shavings, crop
residues, or other organic dry matter soaks up considerable moisture
and, with competent management, may be refed without drying.
Heating for sterilization is often practiced, however.   Since
roughage is a major component of ruminants' diets, its  inclusion
earlier as a litter base may be advantageous.

NOLAND et al [1955-1001] reported that ewes fed ground  chicken
litter did as well as those fed soybean meal and better than those
fed ammoniated molasses as a source of nitrogen.  Steers fattening
on chicken litter did nearly as well as those on cottonseed meal
when the total  feed intake on litter exceeded that on cottonseed
meal by 15 percent.  CAMP [1956=1003, 1959-1003] included 40
percent litter based on peanut hulls or cane pulp in a  formula
proposed for cattle.  He quoted the protein content of  once-used
litter as 21 or 22 percent, and of litter after nine uses as 33
percent.  He advised potential users to avoid rockss nails, and
glass.

CARMQDY [1964-1005] recommended a formula based on 1500 Ib litter,
500 Ib energy feed, 10 Ib dicalcium phosphate, vitamins A and D,
and salt.  On free choice, cattle ate 25 to 28 Ib of litter mix
and 5 to 6 Ib of hay per day.  The litter mix was unpalatable when
wet.

LEW1NGTQN [1964-1010] proposed a mix of 1800 Ib litter, 200 Ib
corn hominy, minerals, vitamins, and hay for cattle.  For sheep he


                                  36

-------
advised a formula of 1600 Ib litter and 400 Ib of broken white
bean mix.  He cautioned that sterilization of the litter would
destroy its feed value.

DRAKE et al [1965-1008] reported that feed efficiency was higher
with 25 percent peanut hull litter than with 25 percent wood
shaving litter.  Both were preferable to a zero-litter control.
However, a 25 percent litter diet was preferable to one of 40
percent.  BHATTACHARYA and FONTENOT [1965-1003] determined that
the optimum litter fraction for ruminants was that for which
the nitrogen from poultry litter was about half of the total
nitrogen intake.  Several authors [1958-1003; 1966-1003, 1012;
1968-1020] have suggested the use of dried citrus pulp, beet pulp,
corncobs, etc., as being more nutritious than wood or hulls in
feeds.

SOUTHWELL et al [1958-1003] advised the running of a chemical test
on each batch of litter before using it because of variability.
BRADLEY and RUSSELL [1965-1004], observing that litter was highly
variable, advised adding vitamin A, and suggested that molasses
might help palatability.  They advised against the use of dusty
litter, as had RAY [1959-1008].

BRUGMAN et al [1964-1004] reported that litter is high in protein
but is low in energy, vitamins A and D, and phosphorus.  BHATTACHARYA
and FONTENOT [1964-1003, 1966-1009] observed that litter compares
favorably with alfalfa hay in sheep rations, but that the percen-
tage utilization of absorbed nitrogen from an autoclaved peanut-hull
litter tended to decrease with increasing levels of the litter
nitrogen.  FONTENOT et al [1966-1029] reported that litter samples
contained 32 percent crude protein on a dry basis.  The average
digestion coefficient of the crude protein was 72.5 percent.
McANDREWS and KERR [1966-1048] observed that poultry litter supplies
protein from undigested poultry feed and from bacteria.

BRUGMAN et al [1969-1014] found no significant differences in feed
efficiency of sheep fed six different rations calculated to have a
crude protein content near 17 percent.  Costs ranged from 4.5 i to
7.1 < per kg.  DAVIS [1956-1001] had reported earlier that feeding
costs had been cut as much as 60 percent by feeding poultry litter
to cattle and hogs.  Drugs in the litter had been responsible for
some stillbirths.

The controversy over the merits (pathogen reduction) and demerits
(reduced nutritive value) of sterilization of poultry litter has
been mentioned.  Additional discussion may be found in several
papers [1967-1004; 1968-1002; 1970-1031; 1971-1094, 1095, 1123,
and 1171].  CASWELL et al [1973-1006] recently described several
methods of sterilization, none of which was found to have a signi-
ficant effect on apparent digestibility or nitrogen utilization.

                                   37

-------
CREA6ER et al [1973-1008] reported the elimination of pathogens
from broiler litter on pine shavings by ensiling.   No drug carry-
over of any consequence was found in their investigation.

OMOHUNDRO [1966-1057] reported that the USDA had advised against
the refeeding of litter because of variability in  nutritive value,
undetermined effect of drugs in the poultry feed,  and the possi-
bility of disease transmission.  KIRK [1967-1008,  1028] announced
that the FDA does not sanction the use of poultry  litter for
animal feed.  BRUGMAN et al [1968-1008, 1972-C014] reported the
finding of drug residues and arsenic in litter-fed lambs,  but of
failing to find either in the carcasses.   CARRIERE et al [1968-1010]
reported that mycobacteria may survive at least a  month in poultry
litter.  In heated litter, competitors may be killed and mycobacteria
may survive two months longer.  GRIEL et al [1969-1030] attributed
abortions which occurred in a herd of cattle which had grazed on
pastures heavily fertilized with dried poultry litter to estrogens
present in the chicken feed.  WEBB et al  [1973-1039], reporting on
tests through two lambing cycles of sheep fed 0, 25, and 50 percent
broiler litter, mentioned possible copper toxicity as the only
problem encountered.
FEEDING LITTER TO POULTRY

Few references were found to the feeding of litter to poultry.
WEHUNT et al [1960-1006] recommended that hydrolyzed broiler litter
be added to chick diets suboptimal in protein.   CHALOUPKA et al
[1968-1011] observed that chickens raised on reused litter are  less
apt to be condemned for Marek's disease than are those raised on
fresh litter.  QUISENBERRY and BRADLEY [1969-1070] reported that
the performance of laying hens on isocaloric isonitrogenous diets
containing 10 and 20 percent of untreated litter and droppings  was
generally better than that of the controls.

GERRY [1972-C035] found that bird weight and percentage of egg
production decreased with increasing percentage of litter in the
feed.
WORM MANURE

Without second thought,  one jumps to the conclusion that meat and
eggs are primary products and that manure is a by-product of low or
negative value.  Such may not always be the case.   HANCOCK [1956-1002]
reported on the raising of' worms on a ration of peat moss, commercial
laying mash, corn meal, and a small amount of molasses to harvest
the compost produced by their excrement.  Broilers raised on the
compost reached 3-1/2 Ib weight in 8 weeks.  The other half of the
same flock, raised on regular commercial broiler feed, required
10 weeks to reach 3 Ib.

                                    38

-------
IMPROVEMENTS IN THE FEEDING VALUE OF MANURE

L. W. SMITH et al [1970-1086] have been investigating treatments of
fecal cell walls to enhance the digestibility of the cellulose and
hemicellulose residues present.  HAMILTON et al [1971-1118] believe
that fermentation may provide a means of improving the quality of
manure as a feed.  SAYLOR and LONG [1972-1136] tested ensilages of
corn field residue or oat straw with poultry manure or cow manure.
The poultry manure yielded higher protein values than the cow manure,
and both were higher than the control which contained no manure.
ANTHONY, as previously cited, has been feeding ensiled "wastelage"
for years with outstanding success.  WALKER and GRAHAM [1972-0103]
are investigating pressure cooking.

McQUITTY and BARBER [1972-1107] cite a Dutch patent [their entry
A-549] for a process of hydrolyzing animal wastes to polypeptides
with H3PO^ at pH values of one to three followed by partial evapo-
ration of the water.  After CaC03 has been added to bring the pH
to five to eight, a loose granular meal results.  They also cite
a 1970 South African patent [A-632] for treating waste with NHs
at proper temperature and pH, digesting it with mineral acid, then
treating the result with inorganic nutrients to obtain modified
polysaccharides.  These may be fed to animals permitting them to
receive in available nontoxic forms, dosages of inorganic nutrients
normally toxic.

HERRICK [1972-1068] has concluded that manure from beef cattle on
high grain rations is best for recycling.  While poultry litter
gave fair results, he did not recommend its use because of concern
over costs, pathogens, drugs, hormones, and antibiotics.  PRICE
[1972-1127] observed that DPW may be more valuable for ruminants
than for poultry since only ruminants can convert urea to uric
acid and thus utilize its nitrogen content.
ATTITUDES

FOERSTER [1966-1028] commented that the renderer has equipment to
convert wastes sufficiently to "circumvent the stigmas, reservations,
and variability inherent in a direct manure product."  KING [1970-
1043] observed that research on refeeding has been slowed by the
checks and restraints of regulatory agencies and the uncertainty
of consumer reaction.  HERRICK [1971-1130, 1131] maintains that costs
will usually exceed nutritive values, and that drugs, hormones, and
antibiotics leave unanswered questions.

TAYLOR [1971-1245, 1246, 1293] stated that the basis of the current
FDA ban on refeeding of litter is that the agency must be assured
of the safety to man and animals.  Specifically, it will require
information on the source of the raw material, a stepwise description

                                     39

-------
of the processing, and a description of the end product and its
intended use.  KIESNER [1972-1078] observed that arsenicals are
routinely fed to chickens but not to man or cattle.   Copper fed to
chickens has reportedly caused trouble in cattle.  60LUEKE  [1972-
1054] noted that the use of organic wastes in animal  feedstuffs
holds great promise provided pathogen transmission is explored,
toxic content is investigated, and FDA approval is secured.

ALAMPI [1971-1005] demanded approval of the reuse of manure.
KIESNER [1971-1144] urged research to satisfy the FDA, and  public
relations procedures to reassure the public.  KOTTMAN and GEYER
[1971-1146] predict that refeeding will be common long before the
year 2000.  ZINDEL [1971-1273, 1310, 1317] tabulated results of
feeding DPW to chickens, sheep, and cattle, then suggested  that the
FDA should be realistic.  He feels that state supervision would be
preferable.  GRAHAM [1972-1056] suggested that the current  emphasis
on ecology might be used to promote acceptance of refeeding.
VAN HOUWELING [1972-1191, 1210] suggested that current research at
Michigan State University and Virginia Polytechnic Institute could
lead to an easing of the FDA ban.
A BRITISH VIEW

The refeeding of manure is prohibited in the United States and in
the nations within the European Economic Community.  It is permitted
in the United Kingdom and Canada.  BLAIR and KNIGHT [1973-1003]
described British practice in a recent article in Feedstuffs.   Only
dried poultry manure is used commercially at preserrtlThe authors
state that "the most important requirement is to reduce a wet,
sometimes semi-liquid material to, at the very most, 15% moisture.
This moisture level is sufficiently low for milling and manufacture
but the manure may not store for long periods.  If the moisture
content is reduced below 10%, the dry manure will store for at least
one year, and probably much longer."  Grinding is employed to remove
lumps which "do not dry out and could harbor bacteria.  Also poultry
manure contains a high number of feathers and other manures may
contain wood shavings. .  ."

With an all-round high standard of cleanliness and hygiene practiced
on the farm and at the dryer, coupled with regular microbiological
and chemical analyses, the authors contend that "in the present
state of knowledge dried  poultry manure that has been properly
processed appears to present no serious health dangers when fed to
ruminants. . .   The use of litter should be considered with care."

They conclude by observing that "in the U. K., dried poultry manure
has been used commercially as a feedstuff for several  years.  No
cases of failure due either to contamination with microorganisms or
feed additives  have been  reported."  However, "very few additives are
now fed to laying stock in the U. K."

                      UTILIZATION OF MANURE BY FISH

Though there are few places in the world that have trouble with the
problem,water can be too pure to support fish life.  The much more
frequently observed phenomenon is that it can be too contaminated
for their survival.

Between the extremes, a fairly wide band of nutrient concentrations
in water exists within which the degradative processes have an
oxygen demand moderate enough to leave adequate supplies of both
oxygen and nutrients for fish.  By controlling the rate of inflow
of nutrients -- and the nutrients may well be manure -- near optimum
conditions should prevail for fish culture.  Such a plan was
proposed at the 1964 winter meeting of the American Society of
Agricultural Engineers as reported'by HART et al [1965-1010].

Experimentation with catfish was conducted by DURHAM et al [1966-
1025] who stocked six ponds 100 ft long, 10 ft wide, and 4 ft deep
at three levels of stocking:  100 fish per pond (4300 per acre),
300 per pond (12,900 per acre), and 550 oer pond (23,650 per acre).
The fish in one group of ponds were fed a ration of cottonseed
cake  (41 percent protein) and milo.  The others received a 50-50
mixture of the cotton seed cake and feedlot manure.  Total daily
ration was approximately seven percent of body weight.

"Although efficiency of gain was greatest in the ponds stocked
with  the fewest fish, total gain was greatest in the heavily stocked
ponds. . .  Ponds stocked at the rate of 23,650 fish produced a
net gain of 3750 Ib per acre. . .  There was no significant difference
between the total gain by the two feeds."

YECK  and SCHLEUSNER [1971-1272], in an excellent survey of the many
means of recycling animal wastes, pointed out that the major constraint
on fish culture as a means of manure disposal is the tremendous area
which would be required to accomodate the relatively light manure
loadings permissible.

MULKEY [1972-1113], in discussing the pollution problem associated  
with  intensive fish farming, observed that the wastes from catfish
production (which include fecal material, metabolic waste products,
and uneaten feed) are a potent source of slug-flow contamination
when the ponds are cleaned out after the harvesting of each fish
crop.  It would appear that the deliberate introduction of manure
into  the operation should be approached most cautiously.

The progress reports on an investigation of the feasibility of
using livestock manure as a feed ration for bullheads and carp
being undertaken by CROSS [1972-C021] are hardly encouraging.   "At
the end of four weeks, two fish [of 14] had died and the  remaining
individuals had lost between zero to three grams weight instead of


                                   41

-------
gaining.  Test  was discontinued.  .  .  We hope to continue next
spring when fish are available."
                       THE FLY:  PEST OR PROTEIN?

A number of the papers abstracted for this report treated, at least
incidentally, the problems created by flies.  Whenever a process
rendered manure less  inviting to flies, this characteristic was
listed among its advantages.  ANDERSON [1966-1004], appeared at
first glance to dissent by observing that an advantage of a manure
pile is that it attracts flies from a large area to lay their eggs.
However, he went on to recommend removal and rapid drying at five-
to  seven-day intervals to destroy the eggs.
 FLY CONTROL

 Quite a number of papers  [1959-1002; 1961-1001, 1002, 1004, 1005;
 1963-1004; 1970-1063, 1064, 1065, 1066; 1972-C046, C087] treat the
 potential of including insecticides in an animal's feed to render
 the manure lethal to flies.  Others suggest the utilization of their
 many natural predators.   ANDERSON'S [1964-1002] list of some of
 these includes parasitic  wasps, earwigs, beetles, and mites which
 feed on fly eggs and/or larvae; spiders and birds which feed on
 larvae and/or adults; and fungi which kill many flies.  The larvae
 of the black garbage fly, OphytLO. te.uc.o-f>toma, attack and feed on
 other fly larvae whenever the latter are present.  "When contained
 with a superfluous number of prey they always killed many more per
 day than they could possibly eat.  The beneficial result of this
 behavior is that the superfluous prey larvae killed by Ophytia. are
 eaten by the remaining living prey species."  He observed [1965-1002]
 that insecticides and flames may be harder on the predators, which
 often tend to remain near exposed surfaces, than on the fly larvae
 which may burrow more deeply into the manure-  Manure removal may
 be detrimental.  "New accumulations of fresh wet droppings were
 considerably more conducive to housefly propagation than to renopu-
 lation by mites."

 HARTMAN [1970-1033, 1971-1124] emphasized that beetles and their
 larvae (mealworms) eat fly eggs and larvae.  The beetles keep the
 manure mass aerated, and  thus less odiferous, in seeking their prev.
 PRICE [1970-1079] and DANKO [1971-1296] also had words of praise
 for the efficacy of beetles.

AXTELL [1972-C004] developed an integrated program of fly control in
 the poultry-producing industry based on biological control, manure
management, and a minimum use of insecticides.  His publications in
J. Econ.  Entomol. 63: 400-405, 1734-1737, 1786-1787 (1970) came to
the writers' attention too late for inclusion in the bibliography.
                                   42

-------
ANDERSON [1972-C002] has issued progress reports on an investigation,
begun in 1964, of the integrated control of flies and the role'of
dung-inhabiting insects in natural recycling of dung.  Some predators
which "feed voraciously on house fly larvae under laboratory
conditions" have been discovered.

RODRIGUEZ and RIEHL [1959-1009, 1962-1009] reported that a cockerel
with access to the droppings under ten confined hens ate all the
fly larvae.  The cockerel was fed at dusk to assure a good appetite
during hunting hours.  They cautioned that the manure should be
kept as dry as possible and that spillage of feed should be avoided.
A 15-week old cockerel will consume about 200 grams of flies per
day.  This exceeds his free-choice consumption of grain or mash.
LaBRECQUE and SMITH [1960-1003] reported similar performance and
stressed, as had RODRIGUEZ and RIEHL, that the cockerels remained
healthy.

GOJMERAC [1972-1213] reported that 250 cockerels, housed in a yard
at the University of Wisconsin to which the daily manure production
is brought, are "doing a good job of fly control."
FLY UTILIZATION

ANDERSON  [1966-1004] observed that fly larvae degrade manure effec-
tively and could provide protein for chickens, animals, or humans.
CALVERT et al  [1969-1017, 1018] described laboratory preparation of
dried fly pupae which contained 63.1 percent protein and 15.5 percent
fat, both of good quality.  They established that the protein from
fly pupae is equivalent to that from soybean meal in chick diets.
The manure converted by the pupae was essentially odorless and had
a loose, crumbly texture.

MILLER [1969-1056, 1970-1136] established a breeder stock of disease-
free houseflies and developed a procedure for collecting their eggs
and distributing them at an optimum concentration on fresh manure.
He reported that either pupae or adult flies killed by heat would
provide a protein-rich feedstuff.  The manure would have become
stabilized with a reduction in moisture content of 50 to 75 percent.
He and SHAW [1969-1058] suggested an alternative method of harvesting
which involves spreading the manure, containing fully-developed
pupae, in a thin layer on a screen under an intense light.  In
avoiding the light, the pupae crawl through the screen.  Harry EBY,
at Beltsville, has modified the process and built a machine capable
of handling manure in ton lots.  Edwin KING, of Clemson, has added
a refinement consisting of a chute and funnel whereby the larvae
who escape the light wind up in deep freeze.

TEOTIA and MILLER [1970-1094, 1095] determined that the optimum
conditions for fly larvae are at a temperature of 25C and a relative


                                    43

-------
humidity of 38 percent.  They will  abandon the manure if the moisture
content reaches 80 percent and are subject to fungal  attack at a
temperature of 37C and a relative humidity of 70 percent.   MILLER
[1971-1172] concluded that the optimum pupal crop has a weight of
about two percent that of the fresh manure.  A 69-page report [1971-
1173], rich in tables and charts and well-documented, summarizes
MILLER'S findings through 1970.

Studies at Beltsville by CALVERT, EBY, MORGAN and MARTIN, in addition
to those already cited, [1970-1012, 1072; 1971-1049;  1972-C017;
1973-1024] have indicated that the excreta from 100,000. hens could
produce 500 to 1000 Ib of pupae per day.  Alternatively stated, fly
larvae can convert 100 Ib of manure from cattle or poultry into 2.5
to 3 Ib of good protein feed supplement (the larvae)  and 50 to 60
Ib of semi-dry practically odorless soil conditioner.  For efficient
operation, the humidity of the manure should be controlled and any
flies which hatch should be confined.

BEARD et al [1972-C007] are conducting similar experiments on house-
flies and various species of glowflies.

HODGETTS [1972-1069], in a survey of American practice written for
a British publication, devotes much attention to the  potentials of
fly culture.
                         BEETLES AND EARTHWORMS

ANDERSON'S observations on the appetites of certain beetles for fly
larvae have been cited.  He also noted [1966-1004, 1971-1009] that
some species of African dung beetles have established phenomenal
performance records for the disposal of elephant and other manure.
He has identified 50 species of flies and 35 of beetles in the cow-
pats in California pastures.  Of these, only the horn fly and face
fly are pests; the others speed the recycling of the manure.   Only
seven species of flies appear to have adapted to life in the fe^d-
lot where manure is churned underfoot.

FINCHER et al [1970-1020] praised the service rendered by beetles in
preserving the nitrogen values of manure by burying it promptly.
They reported that in Australia, where no native bovine or ovine
species existed, cattle dung remained on the ground for years having
an effect somewhat like that of a noxious weed "because cattle will
not graze on the rank growth around these dung pads."  SANCHEZ
[1973-1028] reported enthusiastically on the abilities of Afro-Asian
dung beetles, imported to Texas from strains acclimatized to
Australia, to control manure-breeding flies that affect cattle.
Being nocturnal, these beetles are less subject to elimination by
predators and are thus less apt to serve as intermediate hosts for
parasites of the predators.


                                    44

FOSGATE and BABB [1972-1046] reported that a diet of raw dairy
cattle feces and water with sufficient lime added to maintain a
pH o,f 7.0, would produce a kg of earthworms for each two kg of dry
manure.  The earthworm castings constitute an excellent greenhouse
potting soil.  Earthworm meal, containing 58 percent protein and
2.8 percent fat, is very palatable to domestic cats.
                                  ALGAE

Algae have posed an enticing salvage problem wherever the combination
of water rich in nutrients and adequate sunlight has occurred.
OSWALD [1962-1008] observed that algae production at Richmond,
California, can average 30 tons per acre per year, ranging from a
rate of five tons in December to 60 in July.  This, he~observed,
is two to ten times the peak yield of commercial crops.   For
protein production he quoted the following figures:  algae 12 tons/
acre-year; soybeans, the best vegetative crop, 1 ton/acre-year; and
farm animals 100 to 200 Ib/acre-year.

COMBS [1952-1002] reported that the substitution of chlorella, a
common species of algae, for an equal amount of soybean meal as
ten percent of the basal ration for chicks increased growth and feed
efficiency but led to beak deformities.  GRAU and KLEIN [1957-1001]
stated that the chick can tolerate diets containing up to 20 percent
aluminum-free algae meal.  In obtaining this, alum-floculation
harvesting procedures must be avoided.  ZANEVELD [1959-1010]
surveyed the marine algae of south and east Asia in a text keyed to
161 references.  The uses to which the algae were being put were
usually as human food.

Effective algal activity in waste purification, as WURTZ [1962-1071]
observed in a paper presented at a symposium on ALGAE AND MAN,
depends on having the correct species present in a polluting environ-
ment tolerable to them.

HART and GOLUEKE [1964-1013, 1965-1009], in an economic evaluation
of the production of algae in a manure lagoon, quoted the figures
of 1.3 $/lb of dried algae for concentration, 1 i for dewatering,
and 1.5 to 2 if for final drying.  They concluded that algae was an
uneconomical feed for livestock at the time.  DUGAN, GOLUEKE, and
OSWALD [1968-1014; 1971-1199; 1972-1035, 1122], continuing the
studies at Richmond, have operated an essentially closed-cycle
process in which the wastes from a hen house were fermented in an
anaerobic digestion tank with the effluent draining directly into
an algae pond.  Water from the pond was used in flushing the hen
house and the algae were fed to the chickens.  The pond was aerated
mechanically during the winter.  Algae production was 30 to 40 tons
(dry basis) per acre of pond surface.  Costs of about 2 t per dozen
eggs produced would be incurred in either an algal or mechanical

                                    45

-------
aeration operation.  The value of the nitrogen recovered from the
algae "could be as much as 3 $ per dozen eggs where sunlight is
adequate and land inexpensive."

HINTZ et al [1966-1035] reported that algae have high crude protein
and other food values but contain considerable ash and present some
palatability problems for swine, cattle, and sheep.  They suggested
pelletizing the algae with other feed to mask the flavor.  OSWALD
has observed that different species of algae have quite different
tastes -- and the aromas of jars of powdered dried algae in his
office would corroborate this emohatically.  Chickens, it seems,
have a poor sense of smell.

Several other investigations [1971-1215; 1972-1200, C049] into
various aspects of algal harvesting have been initiated or proposed
recently.
                               HYDROPONICS

DYMOND [1949-1001], in an appendix to VAN VUREN's classical  text,
"Soil Fertility and Sewage," lauded the role of water hyacinth as
a trapper of salt and a purifier of water.  He quoted production
figures of 1100 tons per acre (66 tons of dry matter) and suggested
that the plants be harvested and composted.

BOYD [1969-1011] observed that water hyacinths, water lettuce, and
hydrilla have mean crude protein levels as high as those of  many
high quality forages.  They should be dehydrated before being fed,
and should be harvested at the proper stage since the composition
changes as the plants age.  Later [1970-1009], he added that water
hyacinth is an effective remover of nutrients and that the harvesting
cost may be offset by its feeding value.  Economics dictate  sun
drying before dehydration.  Mosquitoes constitute a problem  in that
the use of pesticides is restricted on feedstuffs.

MINER et al [1971-1119, 1180; 1972-1181] grew water hyacinths in
dilute effluent from an anaerobic swine lagoon in Iowa.  The
evapotranspiration was 3.2 to 3.7 times that from an open water
surface.   They produced 84 tons per acre (5 tons per acre, dry
basis), removing 500 pounds of nitrogen per acre in the process,
and obtained an effluent of good quality.  The plants had value as
cattle roughage and Iowa winters could be depended upon to prevent
undesired proliferation.

EBY [1966-1027] reported on experiments with the hydroponic  growing
of various grasses in greenhouses and in test plots.  To be  useful,
such plants should deplete the nitrogen, phosphorus, and potassium
in the effluent in which they are grown.  They should also be
nutritious to livestock and be easily harvested.  He listed  the
advantages of hydroponic agriculture as being 1) an ability to
utilize manure with a minimum of handling, 2) a potentially greater

                                 46

-------
yield per acre than can be obtained with conventional agriculture,
and 3) a reduction in potential pollution.  LAW  [1969-1043] grew
tall fescue and perennial ryegrass in secondary  sewage effluent in
hydroponic culture tanks.  The nutrient removal  was slight.
HENTGES et al [1972-1067] reported that yearling steers remained
healthy on diets of coastal bermudagrass, water  hyacinth, or Florida
elodea (a plant which grows submerged).  They found aquatic plants
to be adequate in energy but low  in useful nitrogen.  STEPHENS
et al [1972-1151] reported that wide differences exist in the
nutritive value of coastal bermudagrass; water hyacinth, and
hydrilla.

CULLEY [1972-CQ25], in an early progress report  on experiments with
duckweed in Louisiana and Arkansas, mentioned wide variations
observed in crude protein values.  "Spirodela oligorhiza was grown
on an animal waste lagoon, treated municipal sewage waters, and
untreated septic tankwater during the first three months of 1970.
Protein content was 42, 31, and 30 percent respectively on a dry-
weight basis.  Water content of the plant averaged 95%.  Improved
growth rates occurred in poultry  when this plant was substituted
for alfalfa in chicken feed."  Further reports on this continuing
project will bear watching.
                       ANEVALUATION OF  REFEEDING

When ANTHONY  [1971-1013] undertook  an evaluation of the practice and
justification  of  the  refeeding of processed manure to animals, he
began with  the following paragraph.

          "Organic  waste originating from  livestock in the United
          States  far  exceeds  in  quantity the combined organic
          waste output of  the human population  a frightening
          statistic in a pollution  conscious era.  In reality,
          however,  with the exception made for special areas,
          animal  waste is  currently a nuisance rather than a
          calamity.   By application of 20th century man's tools,
          his  ingenuity and his  willingness to act on fact rather
          than hearsay, he can convert this oozing mountain of
          animal  organic waste to one of his great resources.
          A conditioned observation, however, is that the moun-
          tain will continue  to  ooze and man's effort for con-
          tainment  will 'be feeble in response to superficial
          reporting and philosophical prejudices.  Another obser-
          vation  is that conventional sanitary engineering concepts
          developed for human waste disposal offer for animal
          waste a dead end street with calamitous consequence.
          Currently most funded  research in animal waste manage-
          ment is designed to use experimental procedures
          developed for human waste disposal."


                                    47

-------
That refeeding can be done safely has been well established.  Good
housekeeping would be required, but such practice has monetary as
well as public health rewards since the nutritive value of manure
deteriorates with age and careless handling.

British experience with the refeeding of dried poultry waste seems
to have been highly satisfactory.  ZINDEL, FLEGAL and their co-
workers at Michigan State have certainly explored the residual
build-up on recycling  and are satisfied [1971-1273] that relaxing
of present prohibitions would be justified.  ANTHONY'S experiments
with "waste!age" have demonstrated that cattle manure can be refed
with safety and, at least in moderate-sized installations where
brooder cows on pasture can utilize the excess production of steers
on concentrate feed, with complete disposal.

L. W. SMITH [1971-1228] surveyed the literature on refeeding in a
paper which was combined with four others devoted to particulair-
aspects of fecal residues from feed additives, hormones, antibiotics,
and larvicides in a publication of the Agricultural  Research Service,
ARS 44-224-  This collection of papers with its extensive list of
references should be consulted by any serious student of the subject.
Two other papers by SMITH [1972-1145, 1973-1032] explore the scien-
tific basis for refeeding rather fully.

In view of the wide range in nutritive values of manure, capital
investment in housing or pens to provide a desired degree of quality
control, costs of processing the manure, and  costs of disposal of
the excess, no attempt was made to provide an economic analysis of
refeeding.  For a particular situation, with  approoriate assumptions
of the costs of complying with modified FDA regulations, such an
analysis could be prepared.

The evaluation by SENIOR [1973-1029] for Feed Recycle, Inc., is a
good example of such a document.

                        THERMOCHEMICAL PROCESSES


                          COMPOSITION OF MANURE

The composition of manure from various sources is summarized in
Table 1.  These data are adequate for a broad discussion of thermo-
chemical processing methods, but for design of specific manure
processing facilities manure production data for the particular
case considered should be sought.  The three major aspects of
manure composition to be considered are water content, types of
organic materials present, and elemental analysis.

The water content of manure as excreted is normally 75 to 90
percent.  Usually thermochemical processing of manure is done at
rather high temperatures; therefore, this water must be removed
from the manure prior to, or during processing.  As discussed in
Chapter III of this report, drying is a rather expensive process
with a very wide range of reported costs per ton of dry manure.
Drying costs will make many proposed thermochemical conversion
processes uneconomic.  A less expensive route for thermochemical
processing of manure is to produce animals in an arid climate
where natural drying can be utilized to reduce the moisture con-
tent of manure to 10 to 30 percent.  In some cases the need to
dry manure can be circumvented during thermochemical processing
by utilizing a sufficient pressure to keep the water in the liquid
phase.  As discussed later in this chapter, wet pyrolysis or oxi-
dation is a rather expensive process which usually does not yield
profitable products.

The types of organic compounds found in manure are not unusual as
is shown in Table 1.  Manure is largely cellulose and lignin.
These materials are also available from wood and various plant
wastes.  If cellulose or lignin are needed in a particular chemi-
cal process, they can frequently be obtained in a more uniform,
concentrated form from wood, agricultural plant wastes, or even
municipal solid waste than from manure.

The protein which is present in manure is a potentially valuable
material.  This topic' has been given thorough consideration in
chapters IV and V.  In the present chapter protein content of
manure is considered only with respect to its potential for
thermochemical conversion.  This conversion of protein during
thermochemical processing frequently is harmful in that the pro-
tein nitrogen is transformed into organic compounds which contami-
nate the desired products of thermochemical processing.

The elemental analysis of manure determines the relative amounts
of elements which are available in manure for manipulation by
thermochemical processing into desirable products.  Elemental
analyses for manure from beef cattle are given in Table 1.  Since
manure must compete with other raw materials for thermochemical
processing,'a typical feedlot manure is compared with coal, oil
shale, and municipal solid waste in Table 2'.  The moisture content
listed for manure in this table is 30 percent, a water content
frequently observed in manure when scraped from beef feedlots
in semi-arid climates.

Raw materials with high hydrogen and carbon contents are favored
for conversion to synthetic crude oil and natural  gas.  Since
hydrogen is more valuable than carbon, the hydrogen content is
more critical than the carbon content in consideration of materials
for thermochemical processing.

Oxygen in these raw materials has a negative value, since it
reduces the heating value of the raw material.  Oxygen removal by
thermochemical processing also results in loss of valuable hydro-
gen and carbon.  Sulfur and nitrogen in these raw materials usually
represent potential pollution problems, and cause contamination of
the synthetic crude oil and gas which might be produced from them.

In general, all these raw materials for thermochemical processing
are similar and the selection of one or the other of them will
depend on costs and large scale availability.

In summary, manure contains large amounts of water which generally
must be removed to permit thermochemical processing.  As a feed-
stock for thermochemical processing, manure must compete with
other potential raw materials such as coal, oil shale, municipal
solid waste, and plant residues from forestry or agricultural
operations.  The value of manure as a raw material for thermo-
chemical processing is unknown.  To determine its value much
more research is necessary as indicated throughout this chapter.
            PRODUCTS FROM THERMOCHEMICAL PROCESSING OF MANURE

Diamonds could be made from manure, but only an infinitesimal
amount of manure would be disposed of in this manner and, moreover,
diamond production would be more expensive than if other carbon
sources were used.  In a similar manner it might be hoped that some
chemical whose value was very high could be produced by thermo-
chemical processing of manure.  This is only an idle wish since
manure contains largely ordinary substances found in nature such
as cellulose, lignin, protein, and ash.  The products which have
been nroduced from manure are common materials having a low value
                                    51

per pound but a large market.  Large potential markets offer the
opportunity for disposal of significant amounts of manure, if
economics are favorable.

Table 3 tabulates potential products from the thermochemical
processing of manure and lists pertinent references.  Three of
these products, methane, electricity, and ammonia, require no
further discussion since they are products with established markets
and prices.  These prices can be expected to increase, however,
since crude oil and natural gas are becoming more expensive.

Oil produced from manure via pyrolysis or reaction with carbon
monoxide will contain considerable amounts of nitrogen and oxygen
plus small amounts of sulfur.  An analysis made by APPLE [1972-1007]
of oil produced by reaction with carbon monoxide reports 4.2 percent
nitrogen, 7.3 percent oxygen, and 0.37 percent sulfur.  These large
amounts of nitrogen and oxygen cause the heating value of the oil
produced from manure to be about 15,200 BTU per pound.  That of
conventional fuel oil is 18,600 BTU per pound, some 18 percent
higher.  The presence of organic nitrogen in the oil may contribute
to oil instability during storage and to nitrogen oxide problems
during burning.  The rather low sulfur content is an advantage
of manure-derived oil.  Refining of oil produced from manure into
gasoline and petrochemical oroducts would be costly due to the pre-
sence of nitrogen and oxygen.

Oil produced from manure via pyrolysis or reaction with carbon
monoxide is certainly less valuable than ordinary crude oil for the
reasons discussed above.  HALLIGAN and SWEAZY [1972-1060] placed a
value of $2.00 per barrel  on it contrasted to the $5.00 value
assumed by FRIEDMAN et al [1972-1047].  Further investigations are
required to accurately estimate the market value of the oil.

Hydrogenation of manure could potentially produce liquid hydro-
carbons without significant amounts of nitrogen and oxygen, but
manure is more readily reacted with carbon monoxide than with
hydrogen as is discussed later in this chapter.

The char produced from pyrolysis of manure is characterized by a
high ash content, which thus results in a rather low heating value.
MASSIE and PARKER 1973-1020] have reported an ash content of 40
percent, and a heating value of 6,390 BTU per pound for char from
a continuous manure pyrolyzer.  The heating value for a typical
coal is double that, about 13,000 BTU per pound.  Another related
problem with utilizing manure char for fuel is that about eight
times as much ash must be disposed of per BTU used if manure char
were to be employed instead of a good grade of coal.  Since vola-
tile matter has been removed from manure char, it would be more
difficult to ignite in conventional boilers than would coal.

The low sulfur content reported for manure char, 0.3 percent, is
an advantage of manure char over many coals, [SCHLESINGER et al,
1972-1138].  The same reference reports a nitrogen content of 1.1
percent for manure char which is not greatly different from that
of coal.

For the reasons listed above, the value of manure char as a fuel
will be considerably less than that of coal.  Manure char may have
potential as an activated carbon, but no results have been published.
Pyrolyzed sewage sludge has been reported to have modest capabilities
as an activated carbon [BEECKMANS and NG, 1971].*

Low BTLJ gas is a broad term for combustible gas mixtures whose
composition is such that they could not be economically upgraded
for substitute natural gas (SNG).  The usual application for low
BTU gases is power generation and industrial fuels since gas
distribution facilities are designed for high BTU gas.  PARKER et al
[1973-1025] planned to directly utilize low BTU gas from their
manure retort for power generation.

Low BTU gases contain large amounts of nitrogen which result from
the use of air to energize a oyrolysis or a gasification reaction
via partial oxidation.  This nitrogen contamination can be avoided
by using pure oxygen instead of air as the source of oxygen.  The
economics of producing high BTU gas with pure oxygen as a reactant,
or low BTU gas with air as a source of oxygen has not yet been
resolved for coal or manure processing.

Production of fertilizer from manure as a means of manure disposal
appears to involve a contradiction since current manure management
problems are the results of manure being uneconomical as a fertilizer.
If, however, the fertilizer values in manure could be concentrated
as a by-product from thermochemical processing of manure, economical
fertilizer products might result.  This is proposed by PARKER et al
[1973-1025] where sales of ammonium sulfate from the manure pyrolysis
plant were calculated to produce 28 percent of the total income.
Complete conversion of manure to ammonia can be achieved by making
synthetic ammonia from synthesis gas manufactured from manure as
proposed by HALLIGAN and SWEAZY [1972-1060].

After combustion of manure some potassium and phosphorus fertilizer
values remain in the ash.  This material has been recommended as a
fertilizer and soil conditioner by E. G. DAVIS et al [1972-1032].
The manure ash being considered for fertilizer may also contain
materials, such as common salt, which are harmful to plant growth.

          AVAILABILITY OF MANURE FOR THERMOCHEMICAL PROCESSING

The preponderance of manure production is from cattle (88.4 percent)
with hogs, poultry, and sheep contributing 5.9, 4.9, and 0.8 percent
respectively according to L. A. ANDERSON [1972].  Of the total
manure produced, ANDERSON calculates that only 13 percent is pro-
duced in sufficiently localized amounts, such as feedlots having
1000 head or more, to be collected for thermochemical processing.
This may be an optimistic assumption as to the quantity of manure
which can be collected for thermochemical processing since many
papers on thermochemical processing assume manure availability from
0.2 to 2 million feedlot cattle per processing plant as noted by
HALLIGAN and SWEAZY [1972-1060], FRIEDMAN et al [1972-1047], and
PARKER et al [1973-1025].

Table 4, taken from ANDERSON [1972], tabulates the amounts of manure
and other solid wastes potentially available for thermochemical
processing.  These data show that the quantity of manure available
for thermochemical processing is only one third that of municipal
solid waste.  ANDERSON also stated that conversion of manure to
oil would have supplied less than one percent of the nation's crude
oil usage in 1971.  This information may be summarized by stating
that manure is not the solution to the energy crisis, but that
the energy crisis may contribute toward the solution of manure
disposal problems.

Both coal and oil shale are concentrated in large quantities, thus
plants producing 50,000 barrels or more of oil per day could be
constructed.  This size of plant could operate on a scale which
could compete with conventional oil refineries whose size ranges
up to 600,000 barrels per day.

Manure will not be available on such a large scale in a central
location.  For example, if one barrel of oil  were produced per
ton of dry manure processed, a 50,000 barrel per day capacity plant
would require manure from 14 million cattle.

These size factors are important in determining the investment
required per ton of manure processed.  Engineering experience has
shown that, in general, a chemical plant processing 5000 tons of
manure per day would require approximately 2.5 times the investment
per ton of manure processed that a plant processing 50,000 tons  per
day of manure would require, if this large amount were available
at one place.

Sufficient manure is available in central locations to build  1000-
tons-per-day ammonia plants based on synthesis gas from manure as
observed by HERZOG et al  [1973-1013].  This is a typical size for
modern ammonia plants.

Another advantage that oil shale and coal have over manure as a
raw material for thermochemical processing is the amount of research
which has been directed toward their utilization in the past.
Several demonstration-size oil shale plants have been built in the
past 20 years, whereas manure has been thermochemically treated
only in bench scale units or small pilot plants.  Similarly the
Office of Coal Research has supported a large amount of coal pro-
cessing research in reeent years.

Manure processing research can be made more rapid and efficient
by utilizing information available from oil shale and coal studies,
but still research and engineering problems unique to manure must
be defined and solved.  Throughout this discussion of thermochemical
processing of manure, references will be made to oil shale and coal
as a means of utilizing existing information.
                               COMBUSTION

Two publications have  reported small scale experimental studies on
the combustion of manure  in rotary kilns and fluidized beds [DAVIS,
1972-1032] and in a model  laboratory incinerator [SOBEL and
LUDINGTON, 1966-1068],  These small scale experiments are not par-
ticularly helpful in extrapolating to commercial scale units.  LOEHR
[1968-1027] has estimated  the cost of manure incineration to be
about that for incineration of municipal solid wastes, an invest-
ment of $3000 per ton  of  daily capacity and operating costs of $5.00
per ton in 1968.  It is presumed that this estimate assumes manure
of about 30 percent water  content, which is about that found in
municipal solid waste.

Use of manure as a boiler  fuel would permit recovery of energy in
manure as electrical power.  A 110-megawatt electrical power station
could be fueled by the manure from 600,000 beef feedlot animals,
assuming 7.2 pounds of dry matter having a heating value of 6,000
BTU per pound per animal,  and a thermal efficiency of 35 percent.
Larger plants could be built by employing both coal and manure for
fuel.  Being equipped  to  burn varying ratios  of manure and coal
would give the plant considerable flexibility.  Since manure is a
low-sulfur fuel, it would  be possible to burn relatively high sulfur
coal and still meet standards for sulfur dioxide emission.

Combined firing of coal and municipal solid waste is now being
tested in St. Louis with  considerable success as cited by HORNER
and SHIFRIN, INC. [1972].  Only about ten percent of the energy
is being supplied by refuse and 90 percent by coal.

There has been no information published regarding combined firing
of coal and manure under  boilers.  Initially two major technical
                                     59

-------
questions can be raised.  Firstly, would organic nitrogen in the
manure create nitrogen oxide concentrations significantly beyond
those expected from combustion of coal alone?  Secondly, would the
ash from manure create problems in boilers and fly ash recovery
systems beyond those of having to process more ash per unit of
electricity generated?  These questions should first be answered
for conventional firing of pulverized coal.  If the answers were
not favorable, fluidized beds should be considered as should the
use of char from pyrolyzed coal and manure mixtures.  This latter
option would also permit the production of oil from manure and coal.

As an example of the kind of problems to be encountered, consider
the presence of salt in manure.  Sodium and potassium chlorides
greatly increase the corrosion of boiler tubes, particularly when
high steam temperatures are desired.  For a given chloride content,
coals with high ash are less corrosive than coals with low ash as
cited by WYATT and EVANS [1963].  Since manure is high in both
chlorides and ash, its corrosion potential is not obvious.  A
further complication is that the salt content of manure can vary
widely depending on the amount of salt fed the animals.  For a
ration with one percent salt, the sodium content of the manure was
0.86 percent.  If no salt were intentionally fed to the animals,
the sodium content was only 0.15 percent [KLETT et al, 1972-1080].
It should be noted that animals fed no salt gained just as effi-
ciently as animals fed varying amounts of salt up to the one percent
level.

The preceding paragraph illustrates the interrelatedness of many
factors in considering the possibility of manure as a boiler fuel,
from the nutritionist who determines the rations for the feedlot
animals to the metallurgist who specifies alloys for the boiler
tubes and predicts the expected amount of corrosion.

A large electric power generation facility designed to burn combi-
nations of coal and manure would have political problems as well
as technical problems.  Several independently owned feedlots, a
utility company, and federal and state agencies responsible for
different aspects of the facility would have to enter into design
and operation of the facility in a spirit of cooperation.
                                PYROLYSIS
BATCH PYROLYSIS OF MANURE
Pyrolysis is simply a chemical decomposition of organic material
by means of heat.  Pyrolysis provides a direct means for converting
manure into four products:  char, oil, fuel gases, and water con-
taining dissolved organic compounds.  The potential utility of
these streams is discussed earlier in this chapter.
                                    60

Several authors have reported yields for batch pyrolysis of manure.
WHITE and TAIGANIDES [1971-1260] pyrolyzed swine, beef, dairy, and
poultry manure.  The results for pyrolysis of each of these materials
were similar.  These authors did not report the composition of the
manures employed prior to pyrolysis, so it is not possible to relate
pyrolysis yields to the original manure composition.

GARNER and SMITH [1973-1011] have pyrolyzed steer manure under care-
fully controlled conditions.  Their emphasis was on composition of
the liquid products.  Many oxygenated and nitrogenous organic com-
pounds were identified, but none was present in sufficient concen-
tration for profitable separation.  These same authors reported
differential thermal analyses and differential gravimetric analyses
for manure.  They estimated the cost for disposal of manure by
pyrolysis to be rather high  $5.60 per ton.  It should be stressed
that their calculations were for manure containing 80 percent
moisture.

Bureau of Mines personnel have pyrolyzed a wide variety of municipal,
industrial, and agricultural wastes, in facilities originally
employed for testing coal [SCHLESINGER et al, 1972-1137, 1138;
SANNER and WOLFSON, 1971; and SANNER, et al, 1970-1082].  One set of
their data is given in Table 5.

It should be stressed that yields for pyrolysis of manure are a
complex function of many variables.  These variables include manure
composition and particle size, heating rates, maximum temperature,
and pressure in the pyrolysis chamber.  For particular pyrolysis
schemes other factors may also influence the product yields; among
these are the purging of the reacting chamber with gases or the
allowing of liquid products to reflux back into the pyrolysis chamber.
For these reasons considerable judgement must be exercised in drawing
conclusions from published data for batch pyrolysis of manure.
CONTINUOUS PYROLYSIS OF MANURE

Superficially, pyrolysis of manure or any other material is a simple
process:  heating in the absence of air at a sufficient temperature
for a sufficient time to decompose the organic material present,-
then cooling.  When one attempts to plan an economical commercial
pyrolysis plant with minimum pollution potential many major design
problems arise, some of which have not been solved.  It should be
noted that currently pyrolysis of solids is employed only for
preparation of activated charcoal and specialty fuels such as
charcoal and coke.  Commercial pyrolysis of coal or oil shale for
fuel is not currently economical in the United States.  The energy
crisis and pollution control may, however, make large scale pyrolysis
of coal, oil shale, or even manure practical in the near future.

The central problem in the design of a continuous manure pyrolysis
facility is the transport of heat to the manure and, if possible,
the recovery of the heat from the products.  On a laboratory scale,
this is readily accomplished by external heating of the retort
containing the manure, but to extrapolate this concept to a commer-
cial scale or even to a pilot plant scale becomes difficult.

To increase the rate of heat transfer to the manure contained in a
retort, an obvious solution is to stir the manure within the retort.
Injected gases may be used to mix the solids within the retort to
cause increased heat transfer rates from the heated wall, either as
a fluidized bed or while the solids are being entrained through the
retort by the gases.  This latter method has been attempted on
municipal solid wastes but solids feeding problems frustrated efforts
to obtain a significant amount of data on the pilot unit [McFARLAND
et al, 1972-1106].  An externally fired 30-inch diameter fluidized
bed reactor is shown for pyrolysis of noncontestable wastes in the
Hercules waste disposal system.  [WINER, 1971, as reported by BAILIE
and BURTON, 1972].

Another procedure for supplying energy for pyrolysis of organic
solids is to mix hot inert solids with those organic solids being
pyrolysed.  BAILIE and ISHIDA [1972] have considered this procedure
in which fluidized beds were employed both to heat the inert solids
and to mix the hot inert solids with the municipal solid waste to be
pyrolyzed.  The TOSCO oil shale retort mixes hot ceramic balls with
the organic material to be pyrolyzed.  These balls must then be
separated from the spent char, reheated in a separate furnace, and
then mixed with additional material being pyrolyzed.  This rather
complex retorting method has recently been tested with coal [CARLSON,
et al, 1973-1005] and presumably could be employed with manure.

Still another approach for the transport of heat to the solids being
pyrolyzed is to mix preheated gases into the solids either as a
fixed bed, a fluidized bed, or while entrained in the heated gas.
While this approach is mechanically simple, large volumes of gas
must be both circulated and heated resulting in a considerable
investment for compressors and either furnaces or heat exchangers.
The use of furnaces to heat the gas employed to retort oil shale in
a moving bed retort has been reported [CAMERON, 1964].

The cost of furnaces to preheat the gases used to pyrolyze organic
solids can be avoided by burning fuel or a portion of the solid
waste with air, then using the hot combustion gases to pyrolyze
manure or other organic materials.

The general concept of partial combustion to energize the pyrolysis
reaction can be applied to many types of retorts.  Monsanto has
employed a rotating kiln in the "Landgard" system for management
                                    63

of municipal solid wastes [MALIN, 1971].  Workers at the University
of West Virginia have stressed the utilization of fluidized beds
both for pyrolysis and for incineration of municipal solid wastes
[BAILIE and ISHIDA, 1972; BAILIE and BURTON, 1972].  The only
continuous manure retort reported in detail has employed air injec-
tion to energize oyrolysis reactions in a moving bed [MASSIE and
PARKER, 1973-1020}.  Figure 1 illustrates this recently developed
retort.  Manure enters the top of this retort and char is discharged
from the bottom.  Counterflow circulation of gases serves to trans-
port heat upward in the retort to form manure drying and pyrolysis
zones in the upper section of the retort.  Two gas injection cycles
are employed.  Air is injected to generate heat at a combustion front
which moves downward in the retort when the lower portion of the
retort is cold.  The injected air is diluted with oxygen-free gas to
lower the temperatures at the combustion front, so that the ash in
the manure cannot fuse and form clinkers.  When th3 combustion front
nears the bottom of the retort where the associated high temperatures
might damage the grate, air injection is stopped and only oxygen-free
gas is injected.  The oxygen-free gas cools the lower portion of
the retort and continues the pyrolysis and drying of manure in the
upper portion of the retort.  When the lower half of the retort has
cooled, air injection is again resumed.

Feasibility of this retort has been demonstrated in a 6-inch pilot
model.  Table 5 reports the yield of products from this retort.
A major difference in the list of observed pyrolysis products from
the continuous retort and that reported for batch pyrolysis of
manure is the yield of liquid organics.  The continuous retort
yielded about one barrel of oil per ton of manure processed in con-
trast with the 0.3 barrel  per ton reported for the batch pyrolysis.
These data show that manure pyrolyzed in the continuous retort pro-
duces more oil per ton than is reported for average Colorado oil
shale (20-30 gallons per ton).  The increase in oil yield over that
of batch pyrolysis is due to the rapid.removal of pyrolysis products
from the retort by the circulated gases.  A similar high yield of
over 50 gallons per ton was reported when a helium purge was employed
in a simulated continuous manure pyrolyzer [GARNER and SMITH,
1973-1011].

Conceptual process flow sheets have been prepared for a commercial
plant using the Texas Tech University retort and costs estimated
by PARKER et al [1973-1025].  For a plant processing 2,000 tons per
day of 30'percent moisture manure an investment of 14.7 million
dollars has been estimated.  When credit is taken for electric power
generated and ammonium sulfate produced by this plant, the annual
income exceeds the operating expenses, including maintenance, by
$846,000 if. the manure entering the plant be considered to have
zero value.  If no credit be taken for oil and char produced, the
cost per ton of manure processed is $3.71 for a 14 percent rate of
                                    64

return on industrial economics and $0.70 for municipal economics as
described in Table 6.

The preceding pyrolysis methods, with energizing by partial combustion
of the solids being pyrolyzed, result in pyrolysis gases which are
diluted with nitrogen and combustion gases.  For a price, dilution
with nitrogen can be avoided by using oxygen instead of air to oxi-
dize the fuel as has been proposed for several coal pyrolysis and
gasification methods.  Cyclic operation of the pyrolysis processes
can also be utilized to produce pyrolysis gases not contaminated
with nitrogen or combustion gases.  An alternative approach is to
limit the nitrogen content of the mixed pyrolysis gases and combus-
tion gases so that the resulting gas mixture is suitable for con-
version to ammonia synthesis gas.  This approach was proposed by
HALLIGAN and SWEAZY [1972-1060] and is being tested in the laboratory
[HERZ06 et al, 1973-1013].  Their results have established that
manure pyrolysis can be energized by the air which supplies the
nitrogen required in ammonia synthesis gas.  This is a significant
conclusion, but considerable more research will be required to scale
up this process for converting manure to ammonia synthesis gas, and
to estimate its economics.
APPRAISAL OF MANURE PYROLYSIS METHODS

The preceding section illustrates that there are many ways to pyro-
lyze manure.  There are insufficient experimental data and process
economics to identify any one procedure as being the most desirable.
This determination can not be made final  until after commercial
pyrolysis plants have been built and operated.  It is appropriate
now to make some tentative judgements regarding desirable tyoes of
pyrolysis processes to facilitate future research.  One way to make
this appraisal is by analogy with other pyrolysis industries.

Oil shale retorting has been investigated since the early 1800's,
and there has been occasional production of shale oil prior to the
availability of crude oil or when there was an anticipated shortage
of crude oil.  Two of the most intensively researched modern oil
shale retorts, the Union Retort and the Bureau of Mines Gas Combustion
Retort [MATZICK et al, 1968], employ a moving bed type pyrolyzer with
combustion of a portion of the spent oil  shale supplying the energy
for the reaction.  This analogy would suggest that the retort shown
in Figure 1 or a similar retort would be a desirable manure pyrolyzer.
It should be noted that the retort does not have internal gas
distributors as employed in the gas combustion oil shale retort.
These internal gas distributors have been a major problem in gas
combustion retort scale-up studies by the Bureau of Mines and later
by a group of six major oil companies [RUARK et al, 1971].
                                    66

-------
Manure is more easily ground to the small particle sizes required in
a fluidized bed than is oil shale.  For this reason, fluidized bed
pyrolyzers energized by injected air or oxygen should also be given
active consideration in current research.  Whether the product
obtained from the fluidized bed pyrolyzer should be high-BTU gas for
conversion to substitute natural gas, low-BTU gas for use as indus-
trial and utility fuel, or a gas suitable for ammonia synthesis gas
will require detailed economic analysis.  There is considerable
attractiveness to the ammonia synthesis gas concept since this would
release natural gas, now used for making ammonia, for other purposes.

The limiting parameters in the design of commercial manure pyrolysis
plants may be mechanical factors such as particle agglomeration and
elutriation in fluidized beds, crushing of manure fragments in large
retorts, and gas-solids contacting efficiency in both types of
pyrolyzers.  These problems and perhaps other unanticipated problems
must be defined by additional research before profitable commercial
plants can be built.
             CONVERSION OF MANURE TO OIL AND GAS BY REACTION

                    WITH HYDROGENTOR- CARBON MONOXIDE

Conversion of manure  to either  liquid or gaseous hydrocarbons is an
appealing way to  upgrade solid  wastes into desirable products.  The
need for hydrocarbon  fuels has  been emphasized by the present energy
crisis.  This conversion of manure into convenient fuels has been
accomplished in the laboratory.  Commercial large scale application
of these techniques is slowed by a combination of anticipated costs
and technological  problems.  Much of the technology developed for
conversion of coal and oil shale into convenient fuels can also be
applied to the conversion of manure.

A conclusion reached  by Bureau  of Mines personnel is that organic
materials having  a cellulosic structure such as manure were more
effectively processed into oil  by treatment with carbon monoxide and
water  than with hydrogen.  FRIEDMAN et al [1972-1047] have compared
the action of carbon  monoxide and hydrogen on manure and have
suggested a reaction  mechanism  which involves the formation of the
formate ion, which then reacts  with carbohydrate-like materials to
produce oil.  The formate ion can exist only in liquid water;
therefore, high pressures are required to prevent water vaporization
at the temperatures required for the reaction to proceed.  Typical
reaction conditions are 660F,  3,600 psia and a reaction time of one
hour.  Carbon monoxide consumption is 0.4 to 0.7 pounds per pound of
manure, and the oil yield is about two barrels per ton of manure.
To produce the carbon monoxide  needed by the process, and the energy
needed by the processing plant, another ton of manure might be
                                    67

-------
required, reducing the net yield of oil per ton of total manure pro-
cessed to about one barrel.  This is the same oil yield reported for
the continuous pyrolysis of manure.  Most experimental work to date
on this process has been in batch autoclaves, with only data for
sucrose and municipal solid waste having been reported for a small
continuous unit as cited by FRIEDMAN et al [1972-1047],  All processes
which treat solids at high pressures can be expected to have problems
with the feeding of the solids into the high pressure reactor on a
commercial scale.  In addition, this process may encounter difficul-
ties in separation of manure ash from the oil produced.

FRIEDMAN et al [1972-1047] estimate that a plant converting manure
from 200,000 beef feedlot animals into oil valued at $4.00 per barrel
would have to charge $5.00 per ton of manure processed to break even.
Their calculation did not consider income taxes and interest.  If a
ten percent discounted cash flow is required on the invested money
and 48 percent income taxes are paid, a charge of $18.80 must be paid
per ton of manure processed.  Other economic data for this calculation
are given in Table 6.

Steps have been taken to reduce these costs as noted by FU et al
[1972-1048].  One major step is utilization of a carbon monoxide and
hydrogen mixture instead of pure carbon monoxide for the reaction
gas.  Another proposed improvement is the reduction of the operating
pressure and heat requirements by using a low-vapor-pressure oil to
transport the manure into the reactor and supplying only enough water
to facilitate the reaction.  Even with these improvements it is
expected that disposal of manure via reaction with carbon monoxide
will be costly.

Natural gas is becoming scarce, therefore the production of methane
from manure may appear desirable.  There are three ways to accomplish
this conversion.  The method used in the past has been anaerobic
digestion of manure as discussed earlier in this report.  Although
possible, it does not appear economic or more applications of the
method would have been made since this is a well-known process.
Another route is gasification of manure or manure char.  There have
been no experimental results reported for high temperature gasifi-
cation of manure, but presumably the results from manure could be
similar to results from coal,,with appropriate allowance for manure's
high ash content and low heating value.  The third approach to
production of methane from manure is hydrogasification which is the
process of hydrogenation of organic materials at sufficiently high
temperatures and pressures to convert them to gases.  No catalyst is
required.

FELDMANN [1971-1088] reported three hydrogasification experiments on
municipal solid wastes, then proceeded to adapt previous experimental
work and cost estimates for hydrogasification of coal and oil shale
to gasification of municipal solid wastes.  HALLIGAN and SWEAZY

[1972-1060] extended the maximum methane yield calculations of
FELDMANN to manure and they have estimated that 600,000 feedlot
cattle could produce sufficient manure to produce 17 million cubic
feet of methane per day.  Their calculation includes using manure
to manufacture the needed hydrogen and to energize the whole process,
It was intentionally based on 4000 BTU/pound, a very conservative
heat of combustion for manure.

Production of methane from manure will be greatly influenced by
competition from other sources of organic solids, as discussed
previously.  The choice of methods for methane production, gasifi-
cation versus hydrogasification, is also undecided.  The first
commercial coal-to-methane plants in the United States will be
gasification types.
         HYDROLYSIS, WET PYROLYSIS, AND WET COMBUSTION OF MANURE

This section considers the thermochemical processing of manure while
it is still in a water slurry, thereby avoiding the need for drying.
Superficially this is an attractive concept since artificial drying
is expensive, and natural drying is dependent on weather conditions
except in near-desert areas.

The natural substances occurring in manure can be decomposed by
hydrolysis (reaction with water).  With an acid catalyst, cellulose
is hydrolyzed to glucose.  Water, heat, and various chemicals will
disperse lignin found in manure, as is practiced., in making wood pulo
for use in paper production.  Proteins hydrolyze to ami no acids.
Another reaction is between oroteins and lignins to form humus.  There
appears to be no reasonable way to produce marketable products from
this group of possible reactions of manure in water.  If there were a
marketable product in the hydrolyzed manure mixture, its separation
and drying would probably make its cost prohibitive.

One possible exception to this generalization is cooking of manure
prior to refeeding, either for biological sterilization, improved
digestibility, or to facilitate further processing.  Cooking for
refeeding is discussed in Chapter V.  In spite of the limited
potential for thermochemical treatment of manure slurries, work
done in related fields, principally treatment of domestic sewage
sludges, will be discussed in this report for the sake of completeness,

Thermal treatment of manure slurries is limited to temperatures
below the boiling point of water unless elevated pressures are
employed.  With increased pressures, temperatures up to the critical
temperature of water, 705F, might be considered for thermal treat-
ment of manure, but an operating pressure of 3,200 psia would be
required.  Up to this limit the designer of facilities for thermal
treatment of manure slurries is free to choose any temperature he
                                     70

-------
desires then employ the pressure necessary to prevent water evapo-
ration (400F246 psia, 500F680 psia, 600F-~1,543 psia).

Elevated pressure cooking processes are utilized to condition sewage
sludges, that is to make it easier to separate solids from water by
gravity settling and filtration.  BROOKS [1970] has reported on
extensive laboratory heat treatment tests on various sewage sludges.
KRONEBERGER [1972-1086] has described commercial equipment for heat
treatment of sewage sludge.  In this process steam is injected into
a reactor containing the manure slurry to heat it.  A heat exchanger
is used to preheat the incoming manure and to simultaneously cool
the cooked manure leaving the reactor.

The cost to heat treat 600 gallons per hour of pig manure slurry to
380F, hold it for one hour, and cool it has been estimated by the
authors, to be $7.15 per 1000 gallons if a ten percent rate of dis-
counted cash flow is expected on the investment.  Other economic
data for this calculation are given in Table 6.  After heat treat-
ment, something must still be done with the resulting manure slurry.
Based on experience with sewage sludge, the solids will be sterile
and nonputrescible, but the water phase will have a high BOD.  In
some ways thermal treatment of manure could be considerd a substi-
tute for treatment in an anaerobic digester.

T. ALLEN with Envirotech Systems, a firm which produces these heat
treatment units commercially, states that testing has begun with one
of these units as one step in the experimental manufacture of a pro-
tein cake from manure.

In the heat treatment process discussed above, the usual source of
energy is in steam injected into the hot sludge holding tank.  The
need for fuel and for investment in a steam boiler can be avoided by
injecting air into the holding tank.  At high temperatures, above
300F, rapid liquid phase oxidation of the manure will take place
to release the heat needed for the process.  Laboratory tests on
various sewage sludges have been reported for this procedure by
HURWITS et al [1965], but use of wet oxidation to condition sewage
sludge has not been further reported.  Costs may not be greatly
different from the $7.15 per thousand gallons estimated for manure
slurries.  If serious consideration were to be given to thermal
treatment of manure slurries, both steam heating and air injection
should be evaluated.

To provide more complete disposal of manure slurries, sufficient air
could be injected into reactors to oxidize most of the organic
material present.  This is the Zimpro process for oxidizing most
organics in sewage sludges or other organic wastes.  A general review
of this process is given by TELETZKE [1964].  Because air require-
ments are proportional to organic solids content, air compression
costs would be expected to be rather high when this process is
                                 71

applied to concentrated manure slurries.  LUDINGTON [1971] reported
a cost of $12.38 per ton of dry solids for processing poultry manure
by this method.  His information came from a 1967 paper, which was
not available for this report, prepared by the developers of the
process, the Zimpro Division of Sterling Drug.  Since the economic
assumptions behind the cost quoted above were not given, it should
be used with caution.
        CONCLUSIONS REGARDING THERMOCHEMICAL PROCESSING OF MANURE

UNCERTAINTY OF COST ESTIMATES

The basis on which conclusions are drawn regarding thermochemical
processing of manure should be cost or, more hopefully, profit per
ton of manure processed in an ecologically acceptable manner.  These
costs cannot be uniquely determined for the reasons listed below and
discussed in the following paragraphs:

     1.  Economic environment in which the manure processing plant
will function.

     2.  Value of products produced.

     3.  Uncertainties regarding processing plant investment and
operating costs.

The competitive position in which a thermochemical manure processing
plant would operate would depend to a considerable extent on the
interest rates and income tax structures faced by the owner(s).  If
the processing plant were owned by a governmental or public entity
which paid no income tax, and could issue low-interest bonds to
build the plant, costs would be much lower than for a private
corporation.  PARKER et al [1973-1025] have shown that in one case
the cost to process manure in these two economic environments
differs by a factor of  five--$0.71 versus $3.71 oer ton of manure
processed.  The desirability and legality of a county or a manure
disposal district owning and financing a manure processing plant
needs to be explored in a locally coordinated effort by the concerned
governmental agencies and the feedlot industry.

An associated problem regarding public and private economic environ-
ments is that processing costs quoted for different processes
cannot be compared unless they are based on the same economic
assumptions.  Table 6 gives two sets of economic assumptions
employed by PARKER et al [1973-1025].  These data have been used
several  times in this chapter to put various costs on a common
basis.
                                     72

The market value of standard products made  from manure, such as
ammonia and electricity, can be readily  determined.  The value of
oil,or char manufactured from manure is  not obvious  since these
products are different from materials 'now being marketed.  As an
extreme example, if manure char were u,sable as an activated carbon,
and its availability did not depress market prices,  it might have
a value of over $100 per ton; whe;reas , if the char must be sold as
a rather high-ash boiler fuel its; val ue  could be under $3.00 per
ton.

Another problem in calculating manure processing costs is that the
various thermochemical processing methods discussed  have been
tested on a small scale only.  These small-scale results must be
used along with much engineering judgment to determine the size of
commercial scale equipment; and than more judgment must be exer-
cised in estimating investment and  operating costs for the plant.
These estimates are frequently bia.sed with  considerable optimism
by  personnel associated with the particular process.
RANKING OF THERMOCHEMICAL METHODS.

The presently available knowledge is  too  limited  to unambiguously
rank thermochemical processing methods  for  manure.  That ranking
will occur automatically five to 25 years into  the future as second
generation manure processing pl/ants are built.  At this point it
will be helpful to tentatively  rank methods for manure processing
based on the author's judgment.,  even  though other individuals may
rank them in a different order .

First  choice is given to burning air-dried manure in utility boilers
as a portion of the fuel.  Coztl  would also  be burned so that a plant
of economic size could be bui'lt.  The incremental investment required
to handle manure instead of coal should be  small  relative to invest-
ment costs required for other1  thermochemical manure disposal methods.
An intensive effort to obtain  the data  necessary  to assess the feasi-
bility and economics of this method ought to be made immediately.
If negative answers are obta.ined in this  investigation, more stress
could then be placed on othe^r  methods for manure  disposal.

Production of ammonia, usir/g  synthesis  gas  derived from manure as
an intermediate step, is given second ranking.  These plants could
be built in economically competitive  sizes, and the ammonia marketed
near the point of production.   A significant research program,
supported by both EPA and  private industry, has been undertaken
to develop this process [HERZOG et al,  1973-1013].

Continuous pyrolysis of manure in retorts modeled after oil shale
retorts is given third rank.   The primary reason  for this lower  rank
is that sufficient imanure  is  not available  in one location to build


                                     73

-------
a retorting plant of sufficient size to compete with oil shale
retorting plants and coal  processing cilants which might be built
in the future.  If it were necess-ary to produce liquid hydrocarbons
from manure, this method is preferred over those which required
elevated pressures.

Other methods for thermochemical  processing of manure are given
lower probability of commercial success.  Wet oxidation and/or
pyrolysis is ranked low because marketable products are not produced.
Reaction with hydrogen or carbon  monoxide is ranked low because of
the anticipated high investments  required for these plants which
require feeding solids into a reactor at a high pressure, and the
costs of producing the reactive gaseis, hydrogen or carbon monoxide.

                             ACKNOWLEDGEMENTS
A report of this magnitude is not assembled without the cooperation
of a large number of knowledgeable people who have contributed their
advice and time.

The authors are particularly grateful for the continuing consulta-
tion freely extended by their colleagues Robert M. SWEAZY and James E.
HALLIGAN from the preparation of the proposal through the final com-
pletion of the report.

The work of Russell R. GRAHAM, originally co-investigator in the
project, established much of the framework and provided realistic
schedules for the completion of a well-integrated team effort.

Craig B. FOWLER and Gary M. PETTIT, graduate students in Chemical
Engineering and Civil Engineering, respectively, contributed signifi-
cantly to the venture through their conscientious competent pursuit
of reference material.

Ernst W. KIESLING and George F. MEENAGHAN, Chairmen of the Civil
Engineering and Chemical Engineering Departments at Texas Tech,
eased the tasks of the investigators by considerate scheduling of
other duties and by provision of many services.

Mrs. Gloria LYERLA, Interlibrary Loan Librarian at Texas Tech, went
far beyond the line of duty in pursuit of material requested.  Many
of the more elusive items abstracted are there because of her tena-
cious good will.

Miss Sharon ASHLEY made a tremendous contribution to the project in
her typing of the very bulky manuscript, maintaining uniformity of
style despite a raw input which frequently departed from it.  Her
unfailing cheerfulness and competence were an inspiration at all times.

Arthur L. JENKE and Charles D. REESE, Project Officers for the Non-Point
Source Control Branch, Environmental Protection Agency, Washington,
D. C., were most helpful in expediting the project.  Their contributions
are sincerely appreciated.

In addition to the "team" which worked with the project day by day, a
number of people supplied materials requested, discussed the problems,
and displayed research they had underway.  This assured a greater
breadth of understanding of the very diverse circumstances in which
wastes may be utilized or disposed.  Space does not oermit individual
detailing of their contributions, but the authors wish to record their
gratitude to the following:

                        ANNOTATED BIBLIOGRAPHY
Literature on manure seems to be piled as high in the library as
manure is on the guano-rich islands of the South Atlantic.  The
following abstracts represent a useful sampling of some of the best
of the literature but are not a "true" or "valid" sample in the
statistical sense for several reasons.

1.  The early literature, applicable to a period of dispersed grazing
animals in a pre-suburban rural setting, stressed the fertilizer
value of manure.  Its return to the land was considered to be an
obligation to Nature.  Such a solution is increasingly less appli-
cable in the modern context.  In consequence, many of the older
contributions were left unread and unreported in this bibliography.
References to them can be found in the papers abstracted here, in"
the Biological Abstracts, the Journal of Animal Science, Poultry
Science, the publications of the various Agricultural Experiment
Stations, and the popular farm press of the time.

2.  The quirks of lagoons have been analyzed to a far greater extent
than might be judged from a counting of these abstracts.  Good
papers giving sound design specifications for lagoons are apt to be
on the shelf of almost anyone reading this report.  Thus, under the
pressures of time and space, many references found to such papers
were not followed up -- and many an author is due an apology --
which is hereby sincerely extended.

3.  The more exotic solutions or proposals are included to an
extent well beyond their actual proportion in the literature and,
probably, beyond what they deserve when evaluated on abstract merit.
This was done deliberately.  It was the goal of this report to
present an evaluation of the state-of-the-art of manure management
not as a textbook or design manual of approved current practice,
but rather as a compendium of concepts which might aid some inno-
vator by bringing to his attention similar work which might serve
to bolster his solution.  As one means of accomplishing this, a
large number of news-note type papers, often anonymous or authored
by a staff member of the journal in which they appear, are included.
They frequently contain hints of developments well before formal
papers on them have been prepared by the investigators, have run
the gamut of review committees, and have served their time in the
queue awaiting space availability.

The abstracts are grouped by year of appearance and arranged
alphabetically by author within each year.  The numbering system
employed uses the year of appearance followed by a serial number
                                A-l

-------
beginning with '1001'  for each year for papers abstracted in Appen-
dix A, and beginning with 'COOT'  for those in Appendix C.  In some
cases confusion may result in that abstracts or oral presentations
may be cited a year or two previous to formal publication.

Reference is given, where applicable, to abstracts appearing in the
Selected Water Resources Abstracts published by the Water Resources
Scientific Information Center.  This is done by employing the serial
number (consisting of W, a 2-digit designation for the year in which
the abstract was published,  and a serial number within that year)
assigned by that organization.

Five volumes of "Solid Waste Management:  Abstracts from the Literature"
prepared for the U. S. Environmental Protection Agency by John A.
Connolly and Sandra E. Stainback have appeared.  These should be
consulted since they contain abstracts of many papers not included in
this volume.  Where duplication of citation does exist, reference is
made by the notation "C & S" followed by their assigned serial  number.

A very comprehensive annotated bibliography on all  aspects of animal
wastes was prepared by J. B. McQuitty and E. M. Barber of the University
of Alberta and published by  Environment Canada.  Again, many papers
which they abstracted are not included in this volume.  Reference to
their abstracts where duplicate citation exists is made by the
designation "McQ & B" followed by their assigned serial number.

A list of abbreviations used, an author index, and a subject index,

Coprophagy in the Rabb it       ,

Rabbits produce two types of feces:  the familiar dry pellet type
during the day, and a  soft, mucus type "rarely observed because the
animal collects them  directly from the anus and swallows them again"
at night.  Experimental observations indicate that a rabbit may eat
from 54 to 82 percent  of its total fecal production.

 More riboflavin has been found to be present in the feces of fowl
 than in their fe.ed.  Measurements reported in the paper indicate,
 however, that the  increase occurs after defecation.  "The rapid
 synthesis of riboflavin in feces  following defecation makes it
 important that  coprophagy  be prevented in experiments concerning

Precautions  in the Use  of Karroo-Manure

to-day because of its low price and the reduced railage rates on
manures and fertilizers, as well as the scarcity and increased cost
of fertilizers."  Karroo manure, while rich in nitrogen, potassium,
and phosphoric compounds, often has a rather high sodium content
and, thus, may have a deleterious effect on soil.  Its use on
non-sandy soil should be avoided, and on sandy soil should be minimal
Since its chemical content varies widely, karroo manure should be
analysed, batch by batch, before use.  Samples of soils on which it
is used should be checked periodically.

Cow Manure as a Source of Certain Vitamins for Growing Chickens
Poultry Sc1. 21: 554-559

It has been demonstrated that contents of cow rumens may be higher
in vitamins than was the feed.  The feces may concentrate this
several hundred times.  Four experiments in feeding chicks rations
which contained dried cow feces or extracts from them in alcohol or
water are reported.  It was concluded that "cow manure has a marked
beneficial effect on growth in chicks if it is added to a diet defi-
cient in riboflavin.  Cow manure has no deleterious effect on the
growth of chicks if it is added to a complete and balanced diet.
Cow manure contains a factor that stimulates comb growth in both
male and female chickens."

 In experiments on chick nutrition at Beltsville, it was observed
 that precocious  comb and wattle growth resulted when either dried
 cow feces or a 60-percent-alcohol extract of dried cow feces was
 included in the  chick diet.  Further experimentation, reported in
 this paper, indicated that the development of testes and ovaries
 was retarded when chicks were fed dried cow feces, but not when fed

While hatchability has been shown to vary with amount of sunlight and
source of protein in the diet "greater improvement was brought about
by feeding the feces of other birds kept in the battery and fed the

appears that ingestion of feces might help to explain the good hatch-
ability maintained by birds in open-front houses in spite of a low-

Fresh cow manure and cow manure dried at 47C, 80C, and 120C were fed
to poults as 10 percent of their diet as substitutes for alfalfa leaf
meal in a diet already adequate in vitamin A and nearly so in riboflavin,

Livability, growth rate, and efficiency of feed utilization were
unimpaired.  Drying at 80C to 120C is preferable since bacteria patho-
genic to turkeys are destroyed at these temperatures without impairing
nutritive values of the cow manure.

The l>se of Karoo Manure
Farming in South Africa 20: 87-88

Karoo manure tends to produce a brak [alkali] soil which expands
when irrigated and shrinks, forming cracks, when dry.  In a period
of fertilizer shortage, it may be better than no fertilizer.  If
used, it should be restricted to well-drained sandy soils and to
plants tolerant of alkali and salt.  It is safe for most vegetables,
but it should not be used on beans, peas, or trees.

In tests at Beltsville, a soybean oil meal diet was found to be

Jnl. Biol. Chem. 163: 387-400

Cow manure contains a factor shown by a series  of experiments des-
cribed in the paper to be something other than  the vitamins or other
factors previously reported.  It is the only such factor which has
improved the growth-promoting properties of the basal  diet.

The factor is soluble in water or ethyl alcohol and may be extracted
for supplementing rations.  Hens fed dried cow  manure  or fish-meal
transmitted enough of the substance to their chicks to permit them
to grow well on the basal diet.

Cow manure and urine-free hen feces contain a growth factor, appar-
ently synthesized in the digestive system since it appears even when
lacking in the hen's diet, which is neither protein nor chemically-
characterized vitamins.  When corn was replaced by an equal weight
of manure, the following results were obtained for the average
weights of chickens at six weeks (grams):  control 359.5, 5 percent
cow manure 450.8, and 5 percent urine-free hen feces 451.8.

In feeding tests at Beltsville, the addition of 8 percent of cow
manure, dried for 24 to 48 hours at 45C, to an all-mash ration
seriously impaired egg production in a 48-week test.  When, however,
the cow manure was dried at 80C for 24 hours, an 8 percent inclu-
sion had no effect on egg production.  Hatchability was good in
both programs.  There was no effect on body weight or egg size.  It
was concluded that the higher temperature destroyed the androgenic

Tests with groups of laying hens on a corn-soybean meal diet showed
seasonal variation of hatchability when the hens were confined in
open-front houses.  The addition to the diet of the unidentified
dietary factor  of cow manure improved hatchability and eliminated
its seasonal variation.  "It is believed that the improved hatch-
ability of the  low hatching group was due to coprophagy, conditions
being more favorable for the synthesis of the essential dietary fac-
tor in the voided feces during the warmer than during the cooler
portions of the year."

The riboflavin content of chicken feces at the time of voiding is
essentially that of the chickens' feed.  The content will increase
by 100 percent in feces kept at room temperature for 24 hours and
by 300 percent in those kept a week.  Thus bacterial action is
indicated.   Built-up floor litter serves as a potent source of

The Composition and Use of Karoo Manure.  II. Value of Karoo Manure

Farming in South Africa 23: 317-323

Prices in South Africa of Karoo manure and other fertilizers are
tabulated for 1939, 1941, and 1946.  For crops and soils for which
it is suitable, crude Karoo manure may be the best buy in fertilizer.
On the basis of equal dry weights, Karoo manure is preferable to
either farm or municipal compost in fertilizer value.

"In the United States, sheep manure is no longer available for sale
in significant quantities and the price has risen to such an extent
that it is to-day by far the most expensive form in which nitrogen
and phosphate can be bought.  In Texas, the cost per Ib of N and
P205 in 1945 was 9.0 and 5.80 cents when bought as ammonium nitrate
and superphosphate respectively, but in the form of sheep manure
the cost per Ib was 68 cents for nitrogen and 36.5 cents for PzOs,
so that the price of the manure is prohibitive for ordinary farming
purposes."

The subheading, "Its use in sewage effluents, as a trapper of salts
and a water purifier," indicates the importance attached to this
rapidly growing weed considered primarily to be a menace to
navigation.  The author cites its high efficiency in removing nutrients
and considers it to be especially suitable for effluent lakes.  An
acre will produce 1100 tons of plant per year, of which 66 tons is
dry matter.  Cropping is simple.  Use as a compost is suggested.

In the Sudan Gezira the rainfall varies from 100 mm to 500 mm.   The
soil is cracking clay low in nitrogen.  The paper reports studies
of the value of dung from sheep, goats, a dry cow, and a tillage bull
in supplying nitrogen.  Such value was found to be highly dependent
upon the feed.  Urine, rather than dung, is high in nitrogen.
"Animal manure finds a secondary use as fuel, and convenient accu-
mulations are frequently burnt.  The practice is readily understandable,

VAN VUREN, a South African who bases much of his philosophy on

of sewage and animal wastes (p. 149-165) by composting and spreading.

Karoo manure, the droppings of sheep and goats which had been con-
fined nightly in the same kraals (pens) for periods of up to a cen-
tury, is hauled by rail and sold for up to 50 shillings per ton.
Guano, collected from 17 islands in the Atlantic with a total area
of 400 acres, is sold only to bona fide farmers for use on specific
crops.  The 6000 to 9000 tons harvested per year sells for  10
per ton.  "South Africa could easily use ten times the available
quantity."  Bat guano, of an inferior quality, sells for up to  6
per ton.

Methods of preserving barnyard manure to maximize its fertilizing
value are discussed.

with cow manure sun-dried in the open air.  At the 5 and 10 percent
levels both oven-dried and air-dried manure satisfactorily supported
egg production, egg weight, body weight, hatchability, and feed
consumption.  The 15 percent ration of air-dried cattle manure, when
supplemented with herring meal, supported all items except body weight
in the previous list.  The 15 percent ration of oven-dried manure,
without the herring meal supplement, depressed egg production after

Poultry Sci. 33: 1063-1064

Chickens fed the same all-plant diet with added riboflavin had good
hatchability (85 percent) of fertile eggs when on old compost litter,
but only 51 percent when on fresh litter.  "The compost litter pro-
vided adequate vitamin B]2 for maximum hatchability of eggs."  Disease
losses during the first twelve weeks were 14 percent on fresh litter
and 7 percent on compost litter.  "Of 12 consecutive broods, each of
200 chicks, raised on the same compost litter in continuous use for
five years, the disease loss averaged 5.7 percent versus 10.8 percent
of corresponding broods started on fresh litter."

The Use of Ground Chicken Litter as a Source of Nitrogen for Gestating-

Jnl. Animal Sci. 14: 860-865

"Feeding trials were conducted with both gestating-lactating ewes
and fattening steers in which ground chicken litter was used to re-
place conventional protein concentrates.  In the ewe trial the group
fed ground chicken litter performed as well as those fed soybean meal.
Both of these feeds produced results superior to ammoniated molasses
when fed as a source of supplemental nitrogen.  Fattening steers fed
ground chicken  litter did not gain as rapidly as those fed cotton-
seed meal when  both groups were pair-fed for equal feed intake.  By
increasing the  total feed intake of the chicken-litter-fed steers
by 15 percent the rates of gain nearly equalled those fed cotton-
seed meal.  No  digestive disturbances or excessive feed refusals
were noted in either of the  two feeding trials."

Poultry litter is reportedly being fed to beef cattle throughout
the South.  Hogs and dairy cattle also do well  on it.  Feeding costs
have been cut as much as 60 percent.   "No trouble has shown up --

Reprint:  Poultry Digest 15: 272

Worms raised on a ration of peat moss, commercial  laying mash, corn
meal, and a small amount of molasses produce a compost by adding
their excrement.  Broilers raised on the compost reached 3-1/2 Ib
weight in eight weeks.  The other half of the same flock, raised on
regular commercial broiler feed, required ten weeks to reach 3 Ib.
Vitamin B]2 antibiotics, and minerals are assumed to be the
explanation.

WINTERS, a South African farmer, discusses the design and construction
of his plant which successfully produces sufficient methane gas to
operate his farm.  Temperatures are critical in the functioning of
methane-producing bacteria.  At their optimum temperature, 86F,
they can compost cattle manure in 21 days.  Up to five months may be
required at lower temperatures with no significant activity occurring
below 60F.  Pig manure is twice as productive of methane as is
cattle manure.

Engineering Principles  in Handling Liquid Materials
Agr. Engrg. 39: 546-551

Use of liquid manure declined because of back-breaking labor and
inefficiencies  inherent  in separate handling of urine and feces.
Dilution of total waste  followed by pumping for irrigation, as done
in Germany, would be unacceptable here.  "Perhaps the crux in the
handling of liquid manure is the type of pump required to move the
manure from one area to  another."  

Questions  to be answered by an operator contemplating use of liquid
manure include  those on  economics, effect on milk and meat produc-
tion, optimum amount of  water, time requirements for handling stock,
freezing weather, labor, and structural design.

Cattle, being able to convert non-protein nitrogen, can extract up
to 25 percent of the nitrogen present in fowl  manure as protein.
Other nutrients and spilled feed in the manure are also valuable
in cattle feed.  Oxen on a test at Potchefstroom College found a
ration containing 24 percent fowl  manure as a  supplement to mealie
cobs unpalatable at first, but soon acquired a liking for it.   Fowl
manure may also be used with roughage to tide  oxen over a winter.

Only about one-half of the crude protein of hen manure and slightly
more than one-third of that of broiler manure exists as true  protein."
The presence of unidentified growth factors in litter renders  it
"nearly equal to a combination of fish solubles and dried distiller's
solubles and superior to either alone in supplementing corn-soybean
oil meal type rations containing no other recognized source of
unidentified growth factors."

Pig Farming Magazine [Great Britain]
Reprint:  National Hog Farmer v. 6, Mar.  p.  35-36 (1961)

The author describes a power plant he built in South Africa in 1958
in which an anaerobic digester produces sufficient methane gas from
the dung of 700 pigs, about 1600 Ib daily, to power the farm and three
houses free of all fuel costs.  The residue is a soupy black fluid
with a slight ammonia odor which constitutes  a fly-free, easily-
spread fertilizer.  "There is no better fertilizer than the natural
one, and here it is in full strength, neither leached nor bleached,
as it is in composting."

The digester is heated by running the cooling water piping from the
high-compression engine through the digester.  Methane is a clean,
safe fuel which could be compressed for use in tractors, trucks, or
cars.  The cost of the compressor is such, however, that this would
be uneconomical.  Frey's system would work in any climate.

Organic wastes may be decomposed by aerobic bacteria whose oxygen
supply is provided by algae.  The algae may be harvested at short
intervals to feed animals which, in turn, provide more organic
waste.  Studies are under way on the effect of the included bacteria
on the health of the animals.

At Richmond, California, algae production can average about 30 tons
per acre per yr (5 in Dec, 60 in July).  This is 2 to 10 times the
peak yield of commercial crops.  The protein production of algae
is 12 tons per acre per year, of soybeans (the best vegetative source)

Field tests under a variety of conditions established the effective-
ness of controlling flies in manure under cages by permitting
cockerels to scratch for and eat the pupae and larvae.  Management
suggestions are given in the paper.  The manure should be kept as
dry as possible and feed spillage should be avoided.  The number of
larvae and/or pupae consumed per day increases from zero at one or
two days old to 100 on the third day and 8250 in the 20th week.  A.
15-week-old cockerel will consume about 200 grams of flies per day;
this is higher than the free-choice consumption of grain or mash.
All cockerels seemed healthy on the diet.

WATERFALL, C. E.
Farm Drainage - Control of Farm Effluents
Effluent and Water Trtmt. Jnl.  2: 560-561

Legislation in the United Kingdom in 1961 had classified farmlands
as  industrial premises whether operated for profit or not and denied
them access to sewers.  The author recommends "Guile farming" as
practiced on the continent for some years.  This consists of pumping
diluted wastes, as a slurry, from a storage tank to the fields to
fertilize and irrigate.  Some concern is expressed at the loss of
runoff to streams.

"Quite clearly in the interests of good husbandry farm wastes should
be  returned to the land."

Some Problems Remaining in Algae Culturing
Symposium:  Algae and Man.  p. 120-137

Algal activity in the purification of wastes depends on having the
correct species present in a polluting environment tolerable to them.
Ideally, some preliminary decomposition of strong wastes should
occur and the modified wastes should then flow, after being supplied
with oxygen, to algae cultures for final purification.  Such is the
pattern of stream self-purification.

"There are many algae which are a nuisance in natural waters.  Others
are useless:  Though they produce some oxygen during their life, they
become dangerous after their death by the oxygen absorption they may
suddenly occasion, and the production of mud by their mass development,
Most, however, are useful, being at the beginning of life in the
waters, as food for every kind of animals living in the waters."

Sludge digestion as a means of stabilizing manure was studied at the

obtained with domestic sewage sludge.  There are, however, differences.
There is little benefit from, or need for, digestion of dairy manure.
The digestion of chicken manure is feasible and desirable.  Costs are
reasonable.  The digester for a 10,000-hen operation could have a

At a chicken ranch at San Marcos, California, manure, except for a
dry 6-in layer at the bottom, is removed semi-annually and piled
to complete composting.  This requires four to five weeks.  The chicken
ration is controlled to secure a dry manure and ventilation
is optimum.  The ranch has completed three years of successful,

Controlled digestion of manure offers a safe and completely
mechanized system of liquid manure treatment and disposal  with the
following advantages:

     1.  The organic content of the waste is reduced by 50 to 70
percent.
     2.  The waste is well stabilized and ready for final  disposal
in a lagoon or by field spreading for fertilizer.
     3.  The digested waste is a thick, free-flowing liquid without
offensive odor.
     4.  Rodents and flies are not attracted to the end product.
     5.  The fertilizing constituents are preserved.
     6.  Combustible gases with commercial value result.

After discussing the fly problems associated with poultry production
in Orange County, California, the author considers the general  topic
of composting.  Poultry wastes are too wet, too fine-grained, and  of
improper carbon-to-nitrogen ratio for composting alone.  By adding the
proper amount of sawdust, however, the properties of the mixture are
excellent.  Composted manure may be stored without odor for land
spreading when convenient.

Just How Effective are Lagoons?
Compost Sci. 4(3): 25-29

Lagoons for municipal and industrial treatment depend upon algae
and aerobic bacteria.  They are shallow and have a large area.  They
are inapplicable for animal wastes because of the size required  (one
acre per 1200 chickens or 50 hogs), the need for makeup water  to
compensate for seepage and evaporation, and the impossibility  of
getting a uniform mixture of diluted waste.

Farm lagoons, indoor or outdoor, are anaerobic.  They should be
primed with sludge from a municipal plant.  Odor problems may
develop.  Aeration is of no help.  The overflow is highly polluting.

A sealed anaerobic lagoon is a digester.  It has a high capital cost,
requires maintenance and supervision, and involves some risks  of
explosions.  It can, however, produce methane gas utilizable for  fuel
or electricity and the residue is an odorless fertilizer.

An anaerobic lagoon with the supernatant flowing to an aerobic
lagoon is an excellent combination.

The Behavior and Ecology of Various Flies Associated with Poultry
     Ranches in Northern California
Proc. 32nd Ann. Conf. Calif. Mosquito Control Assn.  p. 30-34

Flies on poultry ranches have many natural enemies.  Parasitic
wasps, earwigs, beetles, and mites feed on fly eggs and/or larvae.
Spiders and birds feed on adult flies and/or larvae.  Fungi kill
many flies.  The larvae of the black garbage fly, Opkyna. l&uco&toma,
attack and feed on other fly larvae whenever the latter are present.
"When contained with a superfluous number of prey they always killed
many more per day than they could possibly eat.  The beneficial
result of this behavior is that the superfluous prey larvae killed
by Opkyna. are eaten by the remaining living prey species.  House
fly larvae, for example, in preference to other food in their
developmental medium, are rapidly attracted to and devour members
of their own kind which have been killed and left by Ophyjia. larvae.
Insecticides should be used where only flies congregate rather than
where their predators might be wiped out.

HART set out to determine how thick a layer of slurry (10 to 20 percent

producing fly breeding or other sanitary problems.  A daily layer
1/8-inch thick seemed optimum for summer spreading at Davis, California,
Modifications for different climates and different uses are discussed.
On this basis, one acre of land would serve 230 cattle or 60,000 hens.
Lagoons will accomodate 10,000 to 20,000 hens per acre.  It is
possible, but not practical, to spread the slurry by fire hose and
nozzle from peripheral roads.  Odors were frequent and intense.

Success has been reported in Maine in raising cattle on a ration
of 1800 Ib poultry litter; 200 Ib of corn hominy, minerals and vita-

sheep a ration of 1600 Ib poultry litter and 400 Ib of broken white
bean waste (from a cannery) has been successful.  Poultry litter is
high in protein (14.38 percent to 32.66 percent in tests at the
University of Maine) and fiber but low in energy, vitamins, and avail-
able phosphorus.  "As most of the protein comes from bacteria,
sterilization of the litter would obviously destroy any value the litter
had as feed.  .  .  Drug residues are no problem, due to dilution and
dissipation.  No broilers are currently fed drugs which could be harm-
ful to cattle.  . .  According to spokesmen for Canada's Health of

Standard composting procedures can be improved by provision of forced

sized holes.  It can distribute air uniformly, continuously or
intermittently as desired.

The sheets of plastic should have exhaust spaces left between them.
They prevent top drying by sun and wind, and wetting by rain and
snow.  They prevent fly breeding and odors; they appear neat and tidy.

Mixtures of commercial fertilizers and manure have proven to give
higher yields of crops than manure alone.  The author concludes that
the principal value of manure is in improving soil structure, aera-
tion, nutrient status, organic matter content, and biological
activities.

Composting at a Washington feedlot carrying 5500 steers and at two
million-bird chicken operations in California is described.

The steer manure, mixed with meat packing wastes and blood, is piled
in windrows and turned six times in six weeks.  The compost is bagged
and sold.  The chicken ranches each use rotary drums.  One blends the
manure with an equal amount of sawdust, hay, rice hulls, or cotton
gin trash to improve moisture content.  The other, unsuccessful  to
date, is attempting to operate on straight manure.

Manure as Pullet Feed
Pennsylvania Farmer, 14 Mar.
Reprint:  Poultry Digest 23: 269

Texas Tech experiments with substituting poultry manure for milo in
pullet feeds indicated that as the fraction of the ration consisting
of manure went from 10 percent, to 25 percent, to 40 percent, the
gain for birds was 1.17 Ib (control), 1.19 (on 10 percent), 1.24 (on
25 percent), and 1.27 (on 40 percent).  Feed used per Ib of gain on
these rations was 4.50, 4.77, 5.64, and 6.04 Ib, respectively.  New
trials will substitute manure for protein components, rather than
energy components, of the ration.

Rations designed to equalize crude protein, crude fiber, calcium,

and 100 percent of the soybean protein nitrogen were fed to sheep.
"The data presented indicate that poultry litter nitrogen can be
utilized efficiently by ruminants, especially when the level of
litter nitrogen does not exceed 50 percent of the total  nitrogen
intake.  In important poultry producing areas, litter may represent
an economical source of nitrogen for ruminants.  Before using this
nitrogen source, however, feeders will have to consider the possi-

Research in Virginia, Texas, Georgia, and Arkansas is reviewed
briefly.  While no diseases or drug poisonings have been reported,
the potential danger exists.  Wire scraps or other metal should be
removed by magnets.  The legal status should be investigated at the
time and place of feeding.

Litter is highly variable; each batch should be subjected to chemical
analysis.  Keep the nitrates below one percent.  Feed only loose,
dry, non-dusty litter.  Rice hulls or other plant bases are better
than sawdust or shavings.  Avoid chemical residues, scrap metal, and
glass.  If potability is a problem, the addition of molasses may
help.  Add vitamin A.

The principal contribution of organic manures to crops is nitrogen.
"Organic material is not essential for the growth of green plants."
While decayed organic matter can improve soil texture, "an incom-
pletely decomposed farmyard manure or compost can in fact diminish
the supply of N to the crop because all its own N, and some soil N,
is used by the micro-organisms which rot the straw."

CLARK reports on visits to hog raising facilities in Illinois about

to be unjustified."  Land spreading creates nuisances and is
uneconomical.  Digestion is subject to process failure caused by anti-
biotic effects of hog feed, temperature changes, or shock loads.  The
gas produced has a low production rate and a low BTU value.   Lagoons,
when properly designed and maintained, work.

McKINNEY points out size limitations for lagoons which restrict their
use to small or moderate operations.  For a 10,000-hog-per-year

Producing Algae in Lagoons

Abst:  McQ & B B-010

The production of algae for livestock feed is feasible only in a
completely aerobic lagoon.  The harvesting involves a series of three
difficult steps:  concentration, dewatering and final drying with
costs of 1.3, 1, and 1.5 to 2 tf/lb of dried algae.  Thus, the cost
is more than that of soybean meal.  Algae ponds are sensitive to
overloads.  The supernatant from a digester would be acceptable;
manure would not.  The process is not currently economically feasible
in the U. S., but could ultimately become so.

"Manures are not sewage, and are really not very similar to sewage
solids."

The lagoons proved to be effective in stabilizing organic matter and
in reducing fly problems.  Biological sealing of the bottoms did not
occur to any appreciable extent.

"Infiltration may well control whether a lagoon can be used for manure
disposal. . .  If infiltration does not control the existence of
a lagoon, then odors will be the major factor which will control its
loading rate."  Lagoons should be designed on the basis of BOD per
unit volume translated into lagoon volume per animal.  Lagoons should
be deep and the influent should be discharged near the bottom to
encourage mixing with the digested sludge.  Lagoons must be cleaned
periodically to restore their volume.  Expect no miracles.

This survey of American practice found no single best-solution to
poultry manure disposal.  In the South and Southwest, fly control
can create more problems than manure disposal.

Lagoons can be aerobic only if they have large areas -- 1000 to 1500
hens/acre of lagoon in the North and 2000 hens/acre in the South.
Anaerobic lagoons have odor problems.  Lagoons on porous soil may
cause groundwater pollution, and lagoons subject to freezing may be
ineffective.  They require competent management.  Liquid manure from
lagoons should be spread on land.

Composting is restricted by lack of markets for the product.
Dehydration is generally unsatisfactory due to odors and to difficulty
of producing a uniform marketable product.

The generation of electricity by utilizing the fuel value of gases

handling is simplified since the anaerobic lagoon may be located near

lagoons are preferable.  The effluent from the aerobic lagoon may
find application for non-potable uses.  The two-lagoon system facili-

The exploratory development of formulae for treating cattle wastes

13 tabulations of pertinent data, ANTHONY describes successful pre-
liminary tests feeding 40 parts of washed fecal residue blended
with 60 parts of basal feed.  Later, residues retained on screens
were mixed with basal feed for experiments with a few head of cattle.
"The preliminary tests revealed that the excreta of feedlot cattle
contains valuable nutrients in reasonably large amounts and that
cattle will consume this product when it is combined with other feed
ingredients."  Commercially available screens having been found to be
inadequate for a larger-scale test, a mixture of 40 parts fresh
manure combined with 60 parts concentrate was prepared daily, held
in cans overnight, and fed the next day.  "Results of this test
revealed that combining fresh, unwashed manure with concentrate feed
was not a satisfactory practice in terms of animal gain and carcass
grade."  Either washing or heat treatment was found to be effective
in improving the feed.  Still later tests with an ensiled mixture
of 57 parts manure and 43 parts coastal bermudagrass hay (89 Ib)
blended with 52 Ib ground shelled corn and 1 Ib of Auburn - 65 (urea -
CSM mixture) led to excellent results.  "The coastal-manure haylage
had a pleasing, silage odor.  Animals readily consumed it.  Based
on the results of this study, combining offers the cattle feeder a
challenging opportunity to improve feed efficiency and at the same
time reduces the cost of removing manure from feeding pens."  A

Trickling Filters as a Dairy-Manure Stabilization Component
Proc. Symp. Mgmt. of Farm Animal Wastes  p. 66-68

As a means of producing an effluent of good enough quality for release
to streams or for recirculation as flushing water in a milking parlor
the authors investigated treatment of diluted dairy manure by trickling
filters.  The results of their research indicated that almost any
desired quality of effluent could be secured by appropriate selection
of the loading rate.  To produce an effluent BOD of 200 ppm from 346
to 391 cu ft of tanks per cow would be required.  No cost data are

"There appears to be  no one manure handling system that is optimum

Large poultry facilities in an urban setting cannot employ land
spreading as a method of manure disposal.   The ultimate disposal
techniques apparently available include burial, incineration, wet
oxidation, fluidized bed oxidation, conversion to soil  conditioner
or animal feed supplement, and barging to  sea.  For all these
procedures it is advantageous to have drier manure with its smaller
volume and reduced weight.  Vacuum filtration has been  employed
in the treatment of sewage sludges.  With  appropriate substitution
of chemicals, it is also effective for dewataring poultry manure.
Extensive laboratory testing is reported.   An economic  analysis has
not been completed.

Slurry irrigation has been practiced in Switzerland, Austria, and
Germany for years (Guile System).  In a three-year test in the UK
marked reductions of yield occurred in the second and third years as
the percentage of clover present decreased.  The nitrogen efficiency
as a fertilizer was directly related to the proportion of N^-N
in the total nitrogen.  Because of this,  100 percent urine was several
times as effective in the production of dry matter as 100 percent

In stall housing of dairy cattle, very little bedding is mixed with
the manure but the sloppy material is difficult to handle and to keep
free of fly breeding.  If liquid manure is disposed of by sprinkler
irrigation, a follow-up application of water is important to a)  make
the pastures more palatable to the animals, b) get the fertilizer
into the root zone promptly, and c) flush the irrigation pipe.
"Lagoons appear to be satisfactory provided odors are not obnoxious
to the community, no seepage occurs to contaminate water supplies,
and the fertilizer value can be sacrificed."

Jnl. Agric. Sci. 67: 337-343
Abst:  McQ & B B-448

In fertilizer tests on grassland, applications of a) diluted cattle
urine containing 0.26 percent N and 0.44 percent K supplying 0, 100,
and 400 Ib N and 0, 174, and 697 Ib K/acre, b) fertilizer nitrogen
supplying 0 and 200 Ib N/acre, and c) potash fertilizer supplying 0
and 166 Ib K/acre, were evaluated.

Liquid manure and/or potash fertilizer increased the potassium and
decreased the sodium, calcium, magnesium, and phosphorus contents of
both grass and clover.  Nitrogen fertilizer has a slight effect in
the opposite direction.

Liquid manure increases the ratio K/(Ca + Mg), thus tending to cause
hypomagnesaemic tetany in grazing cattle.

Coprophagy has been observed in cattle fed limited quantities of an

laying hens were fed a ration of which 10, 25, or 40 percent was
manure from cattle fed on the all-concentrate ration slightly fewer
eggs resulted at 25 and 40 percent, and more at 10 percent than in
the control ration with no manure.  Digestibility of dry matter
decreased as the percentage of manure increased.  No differences
in fertility among incubated eggs were observed at the four rations.

Catfish responded well to all-concentrate cattle manure as long as
care was taken to prevent oxygen depletion in the ponds.

 Results of testing three centrifugal, a positive displacement, and

 reported.  At low solids content, pipe friction losses were less than
 for water, but when the slurry became thick, frictional losses were
 much greater than for water.  Pumps should be selected on the basis
 of actual tests with the material to be pumped rather than by extra-
 polating tests with water.  Since manure pumps are designed to be
 non-clogging, efficiencies are low.  The authors recommend a slurry
 with solids content between 1 and 3 (or perhaps 4) percent for all
 manures.  This may simplify manure moving at the expense of manure
 disposal.

 Marine algae have been used for iodine, fertilizer, and feed for
 livestock.  The nutritive values of unicellular algae grown on
 sewage have been studied previously for rats and chicks.  This paper
 reports feeding tests for pigs, cattle, and sheep.  Algae have a high
 crude protein value, about equal to that of soybean or cottonseed
 meal, but with considerable ash.  The digestibility of the cell walls
 is low.  Algae must be pelleted with tasty components or animals will
 avoid them.  Algae appear, however, to have potential as a livestock
 feed, particularly for ruminants, "because of the high content of
 protein, plus significant amounts of carotene, phosphorus, calcium
 and trace minerals."

poultry litter may be composted in place with the resulting composted
litter being dry, odorfree, and unattractive to flies.  The process
may be repeated several times by adding more inoculum and water and
then remixing mechanically.  Such treatment of litter permits the
maintenance of optimum humidity for poultry health without employing
damp litter with its potential for producing ammonia in quantities
toxic to poultry.  The process can restore litter which has been

Land disposal is regarded as being the only acceptable destiny of

Neither aerobic nor anaerobic biological treatments are ideal.

of bacteria normally considered as indices of sanitary quality.
Concrete-surfaced lots produce more pollution than unsurfaced lots
under similar conditions.

Economics of Liquid-Manure Disposal from Confined Livestock

Fertilizer economics are based primarily on N, P, and K values.   These
may decrease severely with storage or with spreading at an unfavorable
time of year-   It is seldom that fertilizer value will  equal  nandling
costs.  While manure has use as a feed, a source of combustible  gases,
a nutrient for  algae, a source of fibers which might be useful  in
oaper manufacture, fuel or a component of adobe building,  none  of
these uses would appear to hold much promise for making manure
economically attractive.

"Manure, even at the lowest rate applied, was more effective than the
highest rate of fertilizer in forage production, apparently because
of the extra N being supplied by manure. . .  Fertilizer influenced
yields only at the first harvest; whereas manure was effective
throughout the growing season."

Either fertilizer or manure caused the clover to vanish within three

Wet poultry droppings produce more odors, promote greater fly pro-
duction, and are more repulsive to handlers than are drier droppings.
Under conditions at Bryan, Texas, baffle boards decreased moisture
content of droppings nearly 50 percent and decreased fly hatch from
70.5 flies per 32 cu in of droppings to 2.5 flies.  Feeding of
bentonite or clay at 2.5 and 5 percent levels of the diet improved
body weight of the hens and increased egg size while reducing moisture
content about 2.5 and 5 percent.  Genetic selection of breeds with
drier feces appears to be a further possibility.

"In truth, there is only one problem with muck, it is just not fashion-
able any more.  It is far easier to say 'it's cheaper to use artificials'
than to attack the problem.  The fact is that among all  concerned,
whether on the farm or off, nobody is very interested."  Such was the
situation in the UK in 1966.

Troubles were largely related to the nearness of neighbors and their
objection to odor.  Trends were away from hydraulic handling to dry
storage awaiting effective land distribution.  Only a few producers
were employing drying and little increase in the practice was
anticipated.

"This paper is concerned with various physical properties of chicken
and dairy cow manure that have a relationship to handling."  The
properties in question are a) basic physical composition (moisture,
total solids, volatile solids, and fixed solids), b) particle density
and bulk density, c) production, d) particle size and distribution,
e) dilution, f) settling rate, g) suspended and dissolved solids,
h) flowability, and i) freezing point.  Laboratory procedures for the
determination of these properties are described and discussed.
Variations due to different feeds, environments, and animal breeds
make the obtaining of a typical sample difficult.  Published values
are scattered widely.  The properties vary so widely that no single
method of manure handling is universally best.

Manure is not sewage and should not be measured by the same yardstick.
Physical characteristics depend strongly upon the ration fed and the
environment.  Old data usually include bedding material and are
oriented toward plant nutrient value.  Chemical and biological
characteristics of major interest are BOD, COD, and PE (population
equivalent).  This latter is defined in several contradictory manners

The effect of manure on soil conditioning and crop yield depends on

carbon to nitrogen, and c) the available nitrogen portion of the total
nitrogen.  "Depending on different arrangements of these three factors,
different effects on crop yield are to be observed, ranging from
depressing to very high.  According to this scale, only liquid manure
has a high or very high yield effect."  Experiments with guile manure

allow a minimum of 1 cu ft of lagoon water volume per pound of total
animal weight confined in a hog-finishing building, plus additional
lagoon volume for sludge storage.  2) For lagoons which will receive
non-uniform and intermittent loadings:  allow a minimum of 2 cu ft of

Animal wastes supply humus to the soil and optimize the utilization

studies on aerobic, facultative, and anaerobic bacteria indicate that
lagoon flora are generally well balanced to carry out decomposition
of a highly-nitrogenous waste.  Land application of liquid manure is

Lagoon systems combining anaerobic and aerobic lagoons may solve
groundwater contamination, odor5 and sludge problems often found with
simple lagoons.

The family farm is being replaced by agribusiness, with an industry's
responsibility for the pollution problems which have resulted.  Despite
the difficulties involved when livestock and crop producers are distinct,
with the crop producer able to use commercial fertilizers at less cost
than "free" manure, ". . . the application of manure to soils is well
justified and desired."

"Generally, the farm animal waste disposal problem is one of collecting
and holding manure until it can be distributed on the land, this being

generally in the spring and fall depending upon the crops being grown.
The difficulties arising  in such a waste  disposal method involve the
size of  tank  required  to  store  the manure, the odours and gases
released, and  in some  cases,  the difficulty of mixing the contents
before disposal on  the land.  .  .  Basically,  treatment and disposal must
ensure four things:  that there is no  hazard  to the health of farm
animals  if disposal  is to farmland;  that  treatment facilities are
flexible in design  and operation to  allow for the various types and
quantities of wastes,  some being produced continually and others
infrequently;  that  the oerformance of  the treatment plant justifies
its capital and operating costs; that  ground  and surface water pollu-
tion are minimal."

Advantages and disadvantages of composting, anaerobic digestion
(too expensive and complicated  for farm use), lagooning,  and aerobic
treatment are discussed.   "... the methods of disposal  available to
the farmer may well control the location  and magnitude of his enterprise
in the future."

The major problems associated with animal waste disposal  are excessive
nitrogen and odors.  Manure may be stored in pits until  opportunity
for spreading occurs or may be handled in anaerobic-aerobic or aerobic
lagoons.  Lagoons are a poor choice in Ontario.  Composting or dehy-
dration depend upon a non-existing market for their feasibility.   Algae
production with feeding of the harvested algae to livestock may have
future potential.  In summary,

     "1.  There is no economical way at present to treat fresh un-

determine its continuous availability, get clearance from the local
health service, contract for dry litter and other ingredients, and
compare costs.  Begin with small amounts watching closely for diarrhea

Effluent Quality from Anaerobic Lagoons Treating Feedlot Wastes
WPCF Jnl. 39: 384-391
Abst:  C & S 67-0345; McQ & B B-070; W71-05423

The functioning of anaerobic lagoons is analyzed.  Their performance
depends on temperature, dilution by washwater or runoff, evaporation,
seepage, and type and amount of loading.  The process is essentially
that of a septic or Imhoff tank.

Land disposal of the sediment is acceptable.  It should, however,
not be permitted to drain to streams without further treatment.
"Anaerobic lagoons are not the complete answer to avoiding the
pollution of natural waters by livestock and feedlot wastes.  When
used in combination with subsequent units to treat the effluent from
the lagoons, anaerobic lagoons may be a useful component process for
livestock and feedlot wastes that have a high solids content."

"While many possibilities for treatment and disposal of animal wastes
exist, few are feasible or realistic."  The authors advocate three
lagoons in cascade:  anaerobic, aerobic, and polishing.  The feedlot
should 'be diked to prevent inflow of surface runoff.  The lagoons
should have sufficient freeboard to hold storm runoff from the feedlot.
The advantages cited are:

     1.  the cost of excavation and bottom sealing is moderate,

     2.  solids handling is simplified by having the upper lagoon
adjacent to the feedlot,

     3.  sludge from the upper lagoon may be disposed of at the
operator's convenience and by pumping as a slurry for field spreading,-

     4.  lagoons may be sized for small area, as deep as possible (the
aerobic and polishing lagoons should have small inflows),

     5.  the effluent should meet most stream quality standards or
may be used for non-potable purposes, and

     6.  the runoff to streams is controlled, and occurs from the
polishing lagoon.

In the discussions TAIGANIDES suggested that odor control problems
"will limit the general application of the system proposed."  DAGUE
recommended the placing of a sedimentation basin ahead of the anaerobic
lagoon, separation of manure and runoff, land spreading of sludge, and
irrigation with the lagoon effluent.  BAFFA proposed pumping to or from
the lagoon to maintain optimum dilution.

In this broad survey of the sources and quantities of nitrogen and
phosphorus which reach surface or ground waters in the United States,
farm animal wastes (p. 354) are cited in terms of population equivalents,
and the contributions of nitrates to groundwater in the vicinity of
feedlots is cited.  The estimated 100 million wild waterfowl (p. 355)
contribute 2 to 5 lb of nitrogen and 0.9 to 2 Ib of phosphorus each

waterfowl may have a bearing on localized eutrophication, their actual
net contribution of total nitrogen and phosphorus to waterways is
perhaps negligible."

Poultry Digest 26: 100-101

An anaerobic digester in a 20-ft-deep well 7 ft in diameter handles
the waste from 500 chickens.  It produces methane gas used for power
and domestic cooking.  The dried effluent is an excellent fertilizer
inasmuch as it contains well-balanced nutrients, provides valuable
humus, and has excellent storing qualities without deterioration.

For start-up a new digester requires "seeding" with the contents of
an operating digester or a period of time for its own bed to become

To test the hypothesis that moisture conditions were likely to be more

authors measured reactions in both over a period of 24 weeks.  They

European and Indian practices which might well receive study in the

     (1)  Spreading by Irrigation.  India mixes sewage and manure,
then pumps the mixture to fields for irrigation-fertilization.  Reuse
of municipal effluent is common.

     (2)  Oxidation Ditches.  Holland is successful with combined
sewage and dairy plant waste water.  More research is needed for
treatment of manures.

     (3)  Digestion of Waste With Gas Utilization.  Germany installed
many plants after World War II.  Most have been abandoned because of
maintenance problems.  India has about 2000 digesters and is planning
to add 9000 more in the next four years.

     (4)  Composting.  May merit study.

Canadians Explain Advantages, Problems in Feeding Poultry Litter

Poultry litter analyzed at the University of Alberta had ranges  in
water content from 9.4 to 18.7 percent, in protein of 13.0 to 29.6
percent, in crude fiber of 6.7 to 22.4 percent, in calcium of 1.05
to 2.33 percent, in phosphorus of 0.59 to 1.79 percent,  and in nitrate
of 0.08 to 0.97 percent.  Rather extensive use is made of litter in
cattle rations in Alberta.  "The enthusiasm for feeding  litter comes
from the decreased cost of the ration rather than from the increased
gains."  Problems encountered in the feeding of litter are heating
(with resultant loss in nutritional value) during storage, cost  of
litter and of mixing in small batches, dustiness, digestive disorders,
scrap metal in the litter, odor, and public aversion.

could be seeded with beneficial bacteria during a holding period
to decompose  the litter material, thereby increasing the feeding value
and  at the same creating an unfavorable environment for the survival

able material.  The project will involve a detailed study of the basic
characteristics of an integrated anaerobic fermentation and algal
growth system for agricultural solid and liquid wastes on a small
pilot plant scale.  To be studied are the reaction kinetics and over-
all performance of an anaerobic reactor or pond followed by an algal
growth reactor or pond.  Recirculation of algal-free effluents will
be employed for odor control in the anaerobic pond and for nutrient
transmission into the algal growth pond.  Area and volume requirements
per unit weight of waste and waste yields of algae per unit weight of
waste will be determined."

An early finding is that the treatment plant should be located near

temperature.  When remoistened, dry manure regains its pollutional
potency.

A feedlot should be designed in such a  way that no surface water flows
into the lot or from one pen to another within the lot.   Runoff should
be detained in a pond and not allowed to reach the natural drainage
courses.  Ideally, such a pond would provide aerobic decomposition.
Practically, in an arid area particularly, evaporation and seepage
may empty the pond before much treatment occurs.

Pond water, diluted from some other source,may be used for irrigation.

A Report on the Engineering and Biological Aspects of Cattle Feedlot
     Runoff Pollution Control
Texas Tech iii + 23 p. processed

This is a report of an investigation of the effects of ration on
quantity and composition of wastes, of the pollutional  character of
runoff, and of the possible methods of control  to prevent pollution
of surface waters.  "It was concluded that the only practical way of
controlling pollution resulting from feedlot runoff is to provide
facilities for retaining the runoff that occurs.   If land is avail-
able, the accumulated runoff can be utilized as irrigation water,
or the land may be utilized simply as the final step in treatment
and disposal of the waste.  If no land  is available for final dis-
posal, retaining ponds must be sufficiently large to allow accumulated
liquid runoff to evaporate."

The authors review the literature on the relative merits of various
litter materials, observing that increased demand and increased
difficulty of disposal would seem to indicate investigation of an
unconventional litter with further reuse value.  Tests indicated
"that poultry litter containing citrus pulp is an excellent feedstuff
for use in ruminant feeding."  While citrus pulp meal is toxic to
chicks when it exceeds about 30 percent of the diet, this is not,
considered to be an actual problem.  FDA restrictions would prevent
such use at present.

"After an initial buildup period, the feces and substrate was inoculated
with aerobic bacteria and aerobic conditions maintained by disturbing
the surface cake at weekly (winter) or twice weekly (summer)  intervals. .
Odors  and flies  have been largely eliminated. . .  The bulk of the fecal
pile was less than half the volume of the control plots due to stabili-
zation of nitrogen and  water losses.  Feathers were digested if they were
incorporated into the fecal pile and the resulting material was a homo-
geneous, odorless fertilizer which has been used in urban gardens.  .  ."

Aerobic Digestion of Cattle Waste
ASAE Trans. 11: 757-761  [ASAE Paper 67-931]
Abst:  McQ & B B-030, G-032; W71-03576

The governing equation for aerobic biological growth is

     organic matter  +  02  + NH3  =  sludge cells  +  C02  +  H20.

That for aerobic digestion is

     sludge cells  +  02  =  C02  +  H20  +  NHg.

A laboratory study of digestion of wastes from dairy and beef cattle
is described.  It was concluded that less emphasis should be placed
on COD, VS, and FS and that more should be placed on BOD as a measure
of pollutional strength.

Anaerobic Lagoons:  Considerations in Design and Application
ASAE Trans. 11: 320-322, 330
Abst:  McQ & B B-026; W71-08220

An anaerobic lagoon may function as a primary sedimentation tank
with the solids left in the unit to degrade until removed periodically
usually when field spreading is convenient.

A deep tank with a small surface area is preferable.  A detention time
of three to five days may be sufficient.  The scum cover which usually
forms is beneficial.  Alkalinity, pH, temperature, and mixing are more
important than rate of loading.  A balance should be maintained bet-
ween acid forming and methane forming bacteria by adding alkalinity
as needed and cushioning abrupt changes.

Seepage should be prevented.  Disposal of effluent and solids is re-
quired, and noxious odors can occur when the balance is disturbed.

This excellent state-of-the-art survey of the pollutional implications
of animal wastes as evaluated in 1967 should be read in its entirety
by any serious student of the subject.  LOEHR summarized his recommen-

Two pertinent quotations from the summary of Part 6 follow:  "The
entire problem of the ultimate disposal of solids remains untouched.
Land application of waste liquids and solids has been used for centuries
but few data have been accumulated on the optimum amounts of material
that can be placed on the land, on proper management techniques, on land
disposal of wastes with  different qualities, on subsequent pollution
that may occur, and on changes in soil conditions that may result.
Major emphasis to date has been on crop response which, while valuable,
provides little information on disposal techniques."

"At present, there is no profitable method of livestock manure utili-
zation and it is unlikely that one will be developed.  Animal waste
handling, treatment, and disposal will cost something.  This must be made
clear to those that produce the animals and the public that consumes
them.  The cost of satisfactory waste treatment will be related to the
desires of the public to minimize pollution from these sources, to the
willingness of the consumer to accept higher meat prices to pay for the
treatment, and to the ingenuity of those in all professional disciplines
in developing suitable treatment systems."

Methods discussed are:

1.   The Deep Pit System.  A depth of 6 ft, 6 in, with cleaning at
     annual intervals or longer is common.  Forced ventilation carries
     the animals' heat over the manure for drying.

2.   Fresh Manure from Laying Battery Cages.  Provide a chute to a
     honeywagon and spread frequently.  Trouble-prone.

3.   Hydraulic Disposal.  A vacuum tanker and/or pipeline may be used.
     Excess weight must be handled, odor problems arise, and land must
     be available.

4.   Poultry Lagoons.  Used in U. S. A. in temperate climates.  Doubtful
     value in Scotland.

5.  Oxidation Ditch ('Pasveer' System).  Little experience yet, but
     promising.

6.   Anaerobic Digestion under Control.  Not perfected for general
     use yet.

7.   Drying.  Successful for large producers.  High capital costs.

8.  Disposal into Main Sewers.  Permission is required.  Slug flow

Lambs were fed a commercial high-energy diet with roughage consisting
of ground corn cobs or wheat straw.  The undigested fiber fraction
from the feces on the first trial was recovered and refed at the same
level as the original roughage.  Performance on the two roughages
differed significantly.  For the corn, of which 10.66 percent consisted
of acid resistant hemicellulose (ARM), 75.5 percent of the acid
hydrolyzable hemicellulose (AHH) and 83.3 percent of the ARH was
digested on the first feeding.  The figures were 0.5 percent of AHH
and 43:4 percent of ARH on refeeding. 'For the chopped wheat straw,
of which 3.45 percent consisted of acid resistant hemicellulose the
percentages digested on first feeding were 65.4 (AHH) and 40.9 (ARH).
Those on refeeding were 9.8 (AHH) and 35.1 (ARH).

Disposal  of untreated slurry on land produces  objectionable odors
and possible health hazards.  Composting first is desirable.

Treatment by lagoons, anaerobic digestion, biological  filtration, and
several versions of activated sludge methods is discussed.

"A digester in continuous operation for 1000 pigs could be expected
to produce 10,000 cu ft of methane per day, equivalent to 6.5 million
BTU.  Of this, 75 percent would be available for useful  power, the
remainder being used to maintain the temperature at 35C."

Biological filtration is expensive.  Tests on  a Pasveer oxidation ditch

Waste from laying hens "has higher NPK values than any other agri-
cultural waste but, because it is  sticky  and difficult to handle, it
is the least appreciated."  Properties are discussed.   Usual disposal
is to land.  Odors may create problems.

Eight different makes of heat dryers are  available on  the UK market.
Lack of marketing experience may be slowing adoption of drying.   Based
on cash return the most promising  markets are (1)  home gardens;
(2) mushroom composting, hop growing, and animal and fish feeding; and
(3) bulk sales to agriculture, horticulture or industry.

Traditional sewage disposal methods are unsuitable for poultry manure.

Animal feeding "might achieve a greater prominence in  the future, but
the quality of the litter and questions of disease control and trans-
mission within animals would be of great  importance."

Animal wastes are neither fluid enough to be pumped, nor dry enough
for bulk transport.  Addition of water or bedding increases volume
to be handled.  Manure is non-competitive as a fertilizer, but has
value as a soil conditioner.  Present disposal methods, discussed
briefly, include anaerobic lagoons, anaerobic digestion with production
of methane gas, oxidation ditches, hydration, coprophagy, composting,
and field spreading.  In the next five to ten years improvements  can
be anticipated to reduce labor, nuisance, and unsanitary practices.
The total system should be optimized in selecting a disposal procedure.

This well written and well documented  (139 references) survey points
up the inadequacy of present knowledge to deal economically with animal
wastes.  More  research is needed.  With concentrations of animals,and
with economies of production of  fertilizers from atmospheric aitrogen,
manure has passed from a valuable commodity to a nuisance1 of wbich. the
cost of transportation exceeds the value as fertilizer.  Lagoons'
provide a questionable alternative means of disposal since 'tfte'y iare
often plagued  by overloading with attendant conversion from an aerobic
to an anaerobic condition, floating  litter, intermittent operation,
aquatic weeds, and sludge buildup.

Anaerobic storage of manure is effective in preserving its fertilizing
value and reducing pollutional potential.  Liquid from piled manure should
be captured.  Manure should not be applied to frozen ground; the run-
off from snow melt carries much of the nitrogen and phosphorus into
streams.  Excessive applications of nitrates may affect groundwater.

and disposal by burning, lagooning, burying, or other methods.

Specific research goals cited are to:

     (1)  Identify and destroy odor-producing bacteria present,
     (2)  Treat manure to make it less attractive to flies and vermin,
          and
     (3)  Develop better procedures for application to cropland,
          avoiding odors and water pollution in the process.

Performance of ewes, heifers, and steers  on  tests of 389, 332, and 126
days respectively are described briefly.   "At the end of the study, the
wastelage-fed ewes were more vigorous and appeared healthier than the
hay-fed ewes."  The wastelage-fed pen of  steers gained 2.57 Ib per day;
those on standard ration gained 2.42.  "Of utmost importance is that
manure fed to cows is fermented by rumen  microbes so that it is
changed into the usual products of digestion, just as conventional
feeds.  Not only do the rumen microbes change the products of manure,
but they prevent the growth of harmful bacteria in the rumen."

Cattle Manure:  Re-Use Through Wastelage Feeding
Cornell Univ. Conf. on Agric. Waste Mgmt.   p.  105-113
Abst:  McQ & B C-107; W71-02715

"Organic waste from cattle reared in confinement can readily be
eliminated as a noxious pollutant and converted to a valuable feed
for animals through wastelage or modifications thereof.   The waste-
lage plan provides two primary advantages:  (a) sanitary disposal  of
organic waste and (b) improved efficiency in feed used for livestock
production. . ."

"Organic waste from ruminants has a chemical constitution similar to
the feed ingested and, in addition, is enriched by the presence of
an abundance of rumen microbial  matter.   Organic waste as it is voided
by ruminants is a fermentation product biologically safe for animals
and it has none of the characteristics of organic waste products
generally classified under the heading 'filth'."

A testing and development period of several  years at Auburn University
is described.   The excess of manure not recycled to steers may be fed
to ewes and beef cows.  If they are on pasture, they provide land
spreading services.  If not, a process of yeast production, still
under investigation, may provide the answer to complete disposal.

Solubilisation of Low Rank Coal with Carbon Monoxide and Water
Chemistry and Industry  1969:  1703

At 4500 psi and 380-400C, lignite underwent a 90-95 percent conversion,
Bituminous coal at the  same pressure and 375-425C underwent less than
75 percent conversion.  Conversion increases sharnly with pressure to
about 1000 psi, and  increases gradually thereafter.  Conversion in-
creases with water content to a 1:1 ratio.  The process is ranid.

Biological Treatment of Poultry Manure Collected from Caged Laying
     Hens
Compost Sci. 10(3): 18-21

Manure was collected from tanks of water and from dry floors beneath
hen cages.  The liquid manure was subjected to primary treatment which
separated it into supernatant, fine sediment and coarse sediment.
Even after 13 days forced aeration, the liquid portion was unacceptable
for discharge to water courses,  The fine sediment concentrated the
odor.  After 30 days in an anaerobic digester, it was unacceptable for
surface spreading.  The coarse sediment, after 14 days incubation at
55PC, was good compost.  Moral:  The manure should not be diluted.

Manure as produced is too moist, too rich in nitrogen, and too fine-
grained for composting.  By adding ground corn cobs, one half pound
of cobs per pound of manure, a mixture resulted which behaved well
on two scales of laboratory testing.  A field test is under way.

Lagoons provide a solution to waste disposal problems low in cost of
construction, operation, and maintenance.   Performance of a chain of
three lagoons on the campus of Washington  State University is described.
With a total area of about one acre the lagoons receive about 20 percent
of the manure from a dairy herd of 100-150 head housed on a concrete-
paved lot.  The balance of the manure is hauled to a storage area.
Effluent from the third lagoon, when such  occurs, is pumped to hay -
fields.  Its possible use as flushing water is suggested.

Land spreading involves smell and the possible presence of toxic
and/pr pathogenic matter.  It is unpleasant labor, subject to severe
climatic limitations and to mechanical breakdown.

Various extended aeration systems -- oxidation ditches, oxidation
tanks, lagoons in series, and lagoons with effluent being treated in
oxidation ditches -- operating in the Netherlands, the UK and the U. S.
are described.  Costs are considered to be reasonable and a good quality
effluent can be produced.

For poultry manure, drying is recommended.  "The end product could be
worth 6 to 11 per ton."  Smell is a major problem.  While scrubbing
can prevent smell, it may not be economical.

Microbiological and Chemical Changes in Poultry Manure Associated
     with Decomposition and Odor Generation
Cornell Univ. Conf. on Agr. Waste Mgmt.  p. 271-291
:Abst:  McQ &B C-l26; W71-02734

Abst.by authors:  "Changes in the microbial and chemical compo-
sitions of batch lots of 'dry' and 'liquid1 poultry manure during
decomposition were related to the production of offensive odors.
The decomposition of uric acid by both aerobic and anaerobic uricolytic
bacteria appeared to be related to the formation of significant
quantities of ammonia.  The number of sulfate-reducing bacteria,
including DuuJL^ov^b^Lo species, increased during the course of
decomposition of liquid poultry manure.  These organisms were impli-
cated as producers of some of the hydrogen sulfide in liquid poultry
waste.  There were apparent correlations between an increase in odor
intensity of liquid manure with increased storage time and the concen-
trations of volatile organic acids, ammonia, and sulfides."

The paper contains a comprehensive literature review with 53 references.

"A study was conducted to determine the maximum number of house flv
pupae that will develop in poultry manure, the effect of this develop-
ment on the physical properties of the manure, and the nutritive value
of the fly pupae.

"Fresh hen feces will support the growth of 3 pupae per gram at a
temperature of 23 to 26C.  At this temperature the feces lose about
20% more moisture than feces without pupae.  Feces with pupae are
essentially odorless, loose, and crumbly in texture and have a moisture
content of about 46%.

"An experiment was conducted with dried, ground pupae (63.1% protein)
diluted with cellulose to contain 50% protein, to determine if this
material would support chick growth.  This protein source was equal
to soybean meal (50% protein) in supporting growth in the chick
through the first two weeks of life."

"Increasingly, atmospheric pollution is being traced to liquid manure
handling systems."  To reduce this, mechanical aeration, even in amounts
well below those found necessary for stabilization of the waste, has
been found effective.  Air pollution from liquid manure under confined
conditions has resulted in suffocation of humans and animals.

Water pollution from runoff is mentioned.

Means of utilizing nitrogen under Canadian conditions are discussed
in some detail.  Corn, potatoes, hay, and pasture have proved to be
effective in Ontario.  In Western Canada, grains, especially where
significant quantities of straw are left at harvest, should not receive
heavy applications of manure.

The authors conclude that the system is odorless, that it provides a
place to dispose of wastes at all times, that nutrients are saved and
returned to the land, that runoff into streams and ditches is minimized,
that pollutional characteristics of all wastes are greatly lowered,
that costs are not excessive, and that little labor is required.

The composition and quantity of wastes on a cattle feedlot are func-
tions of ration fed, of moisture content, and of animal size.
"Accumulated feedlot wastes may undergo practically no change  in the
feedlot other than dehydration, or they may be almost completely
stabilized by composting action on the feedlot floor."  Sprinkling
to promote composting would "undoubtedly result in increased problems
from fly infestation and odor production."

Quantity and quality of runoff is affected by amount and intensity of
precipitation, surfacing material of the feedlot, land slope,  depth
and moisture content of waste accumulation, topographic layout of
the feedlot, and composition of the ration.  Studies on a feedlot at
Lubbock, Texas, are reported and analyzed.

The composition and quantity of wastes on beef cattle feedlots vary
considerably with animal size, climatic variation, and ration  fed.
Cattle wastes, when moist, are readily degraded by microorganisms and
are relished by many insects, particularly flies.

The amount and quality of runoff is affected by the amount and inten-
sity of precipitation and by the antecedent moisture content.   Dry
manure is subject to prompt runoff with erosion; moist manure  tends to
hold further moisture.  More and stronger runoff occurs from paved
than unpaved lots.  Land slope and depth of manure accumulation ob-
viously affect runoff.  While deep layers tend to stabilize, the amount
of fresh manure remains relatively constant.  Dehydrated manure, when
wetted, regains its original potency.  The feedlot layout and  ration
fed also affect runoff.

Design criteria for oxidation ditches have been under study at the
University of Illinois since 1966.  Problems encountered are foaming
(particularly shortly after startup), ammonia odors, and poor
treatment.  These may be minimized by maintaining an adequate velocity
in the ditch by submerging the rotor to about one-third the liquid
depth and using a detention time of 50 days.  The effluent is not
fit for discharge to surface water.

     3)  aerobic systems:

             a.  oxidation ponds,

legislated in 1961 in a fashion which would not merely control  but
prohibit the discharge of many farm wastes, but without having  any
clear idea of what farmers were expected to do to survive."   Resulting
political jockeying by the National  Farmers' Union is described.

The authors, president and consulting engineer respectively for Hupsi
Corporation, describe a process of salvaging poultry manure for ferti-
lizer and feed on which the corporation has a patent pending.

"We propose that troughs of suitable material be placed under the
chickens and that a flow of weak phosphoric acid solution be maintained
in these troughs.  Droppings will be immediately stabilized, denatured
and deodorized upon falling into this solution."

"We intend to do further study of the possibility of extracting pro-
teins, carbohydrates and any other material of animal food value from
the phosphoric acid solution before preparing as fertilizer. .  .  These
materials are preserved in the acid state much as sauerkraut or ensilage."

"By refrigerating the solution flowing under the chickens, the chicken
house is completely and perfectly air-conditioned."

Gross profit is estimated to be $14.50 per ton of dried manure.

The paper describes an  economic  analysis of the costs of land disposal
of poultry wastes  in  a  resort  region of the Catskills where some
relatively long hauls are  involved.  Fertilizer-equivalent values are
attributed to  the  manure with  penalties for the diseconomy of spreading
at the wrong season of  the year  for most effective fertilizer use.
Alternatives (stated  without discussion to be dehydration, incineration,

Animal Wastes -- A National Problem
ASCE Proc. 95: SA 2: 189-221
Abst:  McQ & B B-092; W71-05420

This paper, with its 86 references, is an excellent summary of the
state of the art as of August 1967.  Emphasis in the past has been
upon return of wastes to the land.  With confinement feeding on small
areas, the value of the fertilizer is often substantially less than
the cost of collecting, conveying and spreading.  Moreover, caution is
required to avoid runoff from spread manure and possible infection to
man and livestock.

Methods of handling and disposal discussed include:

     a)  anaerobic digestion (affected by temperature; the effluent
requires further treatment);

     b)  aerobic treatment (extremely large surface areas and volumes
involved if this is the sole treatment used);

     c)  anaerobic lagoons (effective, but should not extend to the
area under slotted floors of confinement sheds);

     d)  anaerobic-aerobic systems (often satisfactory if ultimate
discharge does not reach streams);

     e)  land disposal (to avoid runoff, incorporate soon after spreading;
confinement feeding has altered the feasibility of this method);

     f)  incineration and drying (reduce total volume and minimize
pollution potential); and

     g)  miscellaneous processes ("Because of technical or economic
difficulties, these processes have not found wide application").

The latter include composting (for which a market is required), vacuum
filtration, lime and chlorine treatments (for odor control primarily),
conventional sewage treatment processes (for dilute wastes only),
and feeding of dried manure as a portion of the ration to the same or
other animals.  "At present, there appears to be no profitable method
of livestock manure utilization and it is unlikely that one will be
developed."  Research needs are indicated.

Land disposal of animal wastes has become "doubtful from a profit
standpoint."  Operators with too little land are faced with social  and
legal restrictions on disposal of low-value waste.  Better location
planning of facilities will be required to minimize runoff and odor.

Waste management must be integrated to minimize overall  animal  management.
"The problems we are discussing today have arisen because of rapid
progress in efficiency of animal production without enough anticipation
or understanding of the difficulties that would occur with waste treat-
ment and disposal."

Cost analyses are needed.  Research areas are listed.

Treatment of Wastes from Beef Cattle Feedlots -- Field Results

This paper reports the behavior of a field demonstration complex of an
anaerobic lagoon followed by an aerobic lagoon and a polishing (also
aerobic) lagoon for the treatment of beef cattle feedlot wastes and
runoff.  The ability of such a battery of lagoons was demonstrated.
For most effective use of such a system, it would be preferable to
handle solids semi-dry rather than treat them, the characteristics  of
the lagoons should be understood by the operators, feed should be as
continuous as feasible, and at least half the solids in the anaerobic
lagoon should be left as "seed" at any cleaning.  The final effluent
is not acceptable in a watercourse.

Nitrogen was supplied as soybean oil meal, as hydrolyzed poultry waste
(pressure cooked with 30 Ibs of steam, 30 min), and as cooked poultry
waste (30 min at atmospheric pressure) in isonitrogenous, equicalorie
rations to lambs.  After processing, the poultry waste was dried and
large particles were removed.  Palatability was low.  Performance was
comparable on all diets.

When fed to beef, hydrolyzed poultry wastes gave the best tasting beef,
and dried poultry wastes the poorest in a four-ration comparison.
Results are tabulated.

WPC R$cH>,Snies, QAST-26, 13040 EYX, Chap. 17.  p. 241-255

The value of the nutrients in manure is slightly greater than $1 per
ton.  Some constituents, such as ammonia, are toxic in excessive
applications.  The value of manure as a soil  conditioner has probably
been overrateti. '   <

Manure will decompose in a feedlot with significant losses in nitrogen,
volatile sdlids, and carbon.  Under heavy applications and/or in wet  
soil .manure may become anaerobic.  Denitrification then occurs and the
manure, releases products detrimental to plant growth.

application.  It is concluded that the hydrolysis-fermentation approach
has promise, though the calculated costs of producing Torula yeast from
hydrolyzed solid wastes place this source of protein "at best at the
high end of the current high protein supplement price range."

In an appendix the "City Farm Concept" is sketched.   It is contemplated
that animals would convert municipal wastes to meat with the manure

Biological Digestion of Manure by Diptera

A breeder stock of house flies may be developed from a disease-free
stock.  Fly eggs, deposited on manure available in the fly cages, may
be picked up daily and transferred to fresh manure.  After hatching,
the larvae feed on the manure reducing its moisture content by 60
percent and stabilizing it.  After pupation, two or three days are
available as harvest time.  The pupae provide an excellent source of
protein for chicks.

"Possibly the most practical method of harvesting may be to permit
the flies to emerge as adults under controlled conditions,  they could
then be killed by heat and utilized as a feedstuff."

Diptera which can develop from egg to pupa in five to six days at

harvested by spreading the manure thinly on a screen under an intense
light source.  In avoiding the light, the larvae will crawl through
the screen.  Pupae can be separated from manure by flotation.

In tests larvae removed 80 percent of the organic matter and reduced
the moisture from 75 percent to 50 percent.  About 25 to 30 g of larvae
were produced from each kg of fresh poultry manure.

Livestock Operations and Field-Spread Manure as Sources of Pollutants

Potential pollution sources discussed include runoff from range and
pasture, from cropland following manure application, and from feedlots
and similar unroofed enclosures.  The first is usually negligible, the
second tends to be critical only when spreading occurs on frozen ground
or snow-covered surfaces, and the third required control because of
high-strength wastes with a slug effect due to their entering streams
only as storm runoff.  Diversion channels, settling basins, and
detention ponds are useful as means of control.  Evaporation or
irrigation may be effective for disposal of liquids.

Ground water may be polluted by percolation from feedlots, disposal
areas, or field-spread manure,  the capacity of the soil for absorbing
and transforming nutrients should not be exceeded.

Animal Waste Management to Minimize Pollution
WPC Rsch. Series, DAST-26, 13040 EYX, Chap. 20.  p. 286-297

Management of manure consists of four steps:  collection, storage,
treatment, and utilization or disposal.  Collection may be by wet
methods, which have the advantage of easy mechanical handling by pumps,
or by dry, which have the advantage of minimizing the volume to be
handled.  Storage is used to preserve nutrient value and minimize
pollution until further handling is convenient or appropriate.
Treatment may be by dry systems (drying, dehydration, incineration, or
composting) or by wet systems.  These latter may involve primary
treatment (screening and sedimentation), secondary treatment (anaerobic,
aerobic, or both), and in the future may be extended to tertiary treat-
ment (nutrient removal).  Utilization and disposal is primarily to the
land.  A list of 35 references is included.

these wastes and (c) maintain an acceptable nuisance level."   Digestion
is minimal at low temperatures and foaming is often severe.   Oxidation
ditch effluent should not be released to public waters.

volume of manure, would be more economical than wet handling after
dilution.  Costs ranged from one to ten cents per pound depending on
process chosen and size of lot.  Continued research is necessary.

Land spreading may well be the least-cost method of disposing of poultry
manure.  To minimize risk of pollution and nuisance the spreading must
be properly timed.  This requires storage.  Solid or liquid handling may
be preferable depending upon circumstances.  In any case, good house-
keeping and concern for neighbors must be paramount.

Some Physical and Economic Aspects of Water Pollution Control for

With assumed costs appropriate to the High Plains of Texas, and using
historical precipitation and evaporation records for the area, calcu-
lations are made for the cost of handling runoff vs the risk of over-
flow of the system.  Mechanical (pumping to irrigation or playa lakes)
and evaporative (with provision of an adequate holding pond) systems
are compared.  Secondary considerations such as detrimental effect of
undiluted effluent on crops and possibility of groundwater pollution
are mentioned.

Modified environmental feeding on slotted floors with continuous, rather
than batch, manure disposal would have advantages in increased rate of
gain, reduced uncertainty, better animal health, reduced labor require-
ments, elimination of air pollution, and simplified waste treatment or
disposal.  The disadvantages would include tripling of capital costs,
forfeiture of natural climatic advantages where they exist, and increased
annual operating costs.

Reporting primarily on practice in Holland, the author emphasized the
necessity of avoiding discharge of farm wastes to rivers because of the
high BOD present.  "The usual way to dispose of farm wastes has been
and still is to use them as an organic fertilizer on farm land."  Lack
of balance between production and demand for fertilizer has led to
experimentation with oxidation ditches.  Construction is described and
cost data given.

Swine Wastes, Characterization and Anaerobic Digestion

The optimum conditions for anaerobic treatment of hog wastes have been
shown to require expensive facilities and close supervision.  Where
partial treatment will suffice, as in the liquification of the wastes
to permit reuse as flushing water and to ease handling prior to
ultimate land disposal, anaerobic treatment may be effective at moderate
cost.

A Method for the Treatment of Animal Waste to Control Ammonia and

Abst:  McQ & B B-282; W71-00332

"Flake paraformaldehyde as it disintegrates has the unique ability to
neutralize ammonia gas produced by animal wastes by a direct chemical
reaction.  Because flake paraformaldehyde liberates formaldehyde gas
slowly, it has an antimicrobial action that destroys a variety of
organisms capable of producing noxious gases, thus minimizing odors
that accompany decaying animal wastes for a prolonged period.  Tests
show that because of its action the treated animal wastes retain
nitrogen at a much higher rate than untreated wastes."

The advantages of removing water from manure are a) a change in
handling characteristics,  b)  a reduction in  weight and volume, and
c) a reduction in offensive odor.  Water may be removed mechanically,
thermally, or by absorption in litter or bedding.  Mechanical  means
are ineffective and/or expensive.  Thermal removal by natural  evapo-
ration is, slow, the rate of water loss from  a manure surface being
less than that from a free water surface.  Time requirements vary
widely from sample to sample.

The findings of a 1968 survey are presented.  In Ontario, land spreading
is universally practiced but difficulties are anticipated as confinement
feeding on small land holdings becomes more general.  Storage of up to
six months is required to avoid spreading on frozen ground or snow.
Treatment for release to water courses would be uneconomical.  All
lagoons in the province have produced more or less  odor.

"This status report estimates the pollution potential  of farm animal
wastes; outlines the present methods of handling liquid manure from
confinement operations; tabulates animal waste characteristics, loadings,
and population equivalents; gives field data and experiences on typical
water pollution control facilities; and concludes with guidelines on

A series of experiments with an oxidation tank handling diluted
poultry manure indicate that such an installation would be practical
for a farmer in that it is reliable, requires a minimum of maintenance
and operation, and produces a nuisance-free effluent in that it has no
odor and does not attract flies.  The effluent is still too potent for
stream discharge.  Liquid and solids in the slurry are easily separable
and may be disposed of by land spreading.

Studies at Guelph, Ontario, were undertaken to provide guidelines  for
determining the optimum application of manure to fertilize crops and
the maximum safe application without polluting surface or ground water.
Crops vary in their use of nitrogen.  Corn, potatoes, hay, and pasture
grasses, particularly on coarse-textured soils, use large quantities
of nitrogen.  Enzymatic denitrification, a biological process accom-
plished by facultatively anaerobic bacteria, may be employed to dispose
of nitrogen provided proper nutrients and temperatures are available
for the bacteria.

Aerobic Decomposition of Solid Wastes from Cattle Feedlots

Aerobic composting is an effective means of handling wastes from beef
feedlots in the semi-arid High Plains of Texas.  The fresh manure may
be placed in piles and turned weekly.  Fly larvae deposits may be
intense the first week.  They cannot survive the temperatures which
develop within a pile, and the weekly turning period provides adequate
fly control.

Experiments with a SB-gallon drum rotating at 3/4 RPM and stationary
except for two revolutions twice per day indicated "that stabilization
points at which insects are no longer -attracted to the mass, bacteria
of purification can no longer be actively supported, coliform bacteria
are no longer detected, and high internal temperatures can no longer
be maintained are reached at compost time periods of less than ten
days."

Laboratory and field investigations on concrete and dirt feedlots led
to the following conclusions and recommendations:

     1.  Conventional aerobic treatment processes are not economically
feasible.

     2,  Undiluted or untreated runoff from feedlots is not suitable
for direct application as irrigation on most field crops.

     3.  Anaerobic treatment processes would appear to offer the best
hope for treatment of feedlot runoff.

     4.  The potential pollution hazard to groundwater needs thorough
investigation.

The findings are applicable to the conditions  of the High Plains of

Laboratory and field tests of the response of a number of varieties of
plants to irrigation with the runoff from concrete or dirt-surfaced
beef cattle feedlots are reported and discussed.  Runoff from the
concrete surfaces was more damaging than that from the dirt lots.  It
was.concluded that "runoff from feedlots operated in a conventional
manner does not appear to be suitable for direct application as
irrigation on most field crops.  It appears that such runoff should
be applied in limited amounts only to crops with a high salt tolerance
and that it should be diluted with fresh water to the maximum possible
extent."

Concern was expressed that groundwater might be polluted under unlined
ponds or agricultural land irrigated with feedlot runoff.

Problems overcome in preparing dried poultry manure as an acceptable
(25-50 percent of ration) feed for ruminants in England were the
assuring of a sterile product free of bacteriological contamination or
extraneous matter with no trace of burning or charring.  Unpleasant
smells during the processing were reduced and a market was developed
for the feathers which were removed, dried, and cleaned.  The product,
called "Toplan," sells for $28.80 per ton, thus saving 30 percent on
feed costs.  The contents are crude protein 26.6 percent, carbohydrates
38.7 percent, ash 15.24 percent, moisture 7.68 oercent, and oil,

This is a good brief summary of the state-of-the-art in beef feedlot
waste disposal with citation of many original papers.  Practice in
Southwestern feedlots is generally to stockpile manure, often after
preliminary spreading for drying, until it is convenient to transport

either pumped to fields for  irrigation or to lagoons for evaporation.
When used for irrigation, feedlot runoff is diluted with well water.

Fresh poultry manure -- with a moisture content near 75 percent, a
carbon-to-nitrogen ratio near 10, and a structure consisting of many
fine particles -- must be mixed with drier, coarser material with a
higher carbon-to-nitrogen ratio to provide good raw material for
composting.  In the experiments reported, kiln-dried corncobs ground to
pass a quarter-inch screen were mixed with the poultry manure in the
ratio of two parts manure to one part corncobs.  Laboratory studies
indicated that optimum aeration rate for the production of a stable
sanitary compost was four litres of air per sq m per min for every 10 cm
depth of composting material up to a maximum depth of about 2.4 m.

Disposal should be a short-range objective.  Composting, now more an
art than a science, deserves study.  Further investigations of two-layer
lagoons with, perhaps, water from the top (aerobic) layer being used
for poultry shed flushing; of lagoon liner requirements as a function
of permeability; and of aeration capacity required for odor control  as
a function of climate are needed.  Would a plastic bubble over the
lagoon permit the capture of methane gas?

In the longer run, manure should be salvaged.  The value of U. S.
poultry manure, based on 8 /lb for N and 6 $ per Ib for P and K, is
$40,000,000 per year.  Trace elements which may be absent in chemical
fertilizer would increase the figure.  Work at Michigan State, Penn
State, and elsewhere on the pasteurization and processing of wastes
for livestock feed holds much promise.

matter undergoes breakdown with little reduction in BOD or COD;  in the
second, methane and C02 are released and the waste stabilizes.

Design criteria are empirical.  The functioning is similar to that of
a sludge digester.  A starting-up is facilitated by seeding with
methane-producing bacteria,  temperature must be above 15C, thus
regional connotations occur in design specifications.   Research is
needed to enhance the performance of this very effective process.

Value of Processed Poultry Waste as a Feed for Ruminants
Jnl. Animal Sci.  31: 107-111
Abst:  McQ & B B-226

Interest in the feeding of waste products arises from the possibility
of disposal of the waste in a beneficial and economical  manner, from
the avoidance of pollution, and from the resulting freedom to shift
crop land from feed production to food production.

Trials are described in which autoclaved, cooked, and dried poultry
wastes were fed to sheep and steers.

feces attracted the most species of coprophagous beetles.  While some
beetles serve as intermediate hosts of various helminths of domestic
and wild animals, their service in preserving the nitrogen value of
dung by prompt burial is valuable.  Because of inadequate numbers of
dung beetles in Australia, cattle dung remains on the ground surface
for years "and has an effect on the pasture somewhat like a noxious
weed because cattle will not graze on the rank growth around these
dung pads."  The paper lists 20 references.

 Iowa Beef Packers  at Denison,  Iowa, began  testing confined cattle
'feeding over  an oxidation  ditch  in November,  1969.   First year results
 were most promising.  Cattle in  confinement had better winter and sum-

 redesigned to be  continuous rather than to consist of two "racetracks"
 side-by-side.   Aerators were moved to  the  center to  avoid centrifugal
 interference with  uniform  action.  Water was  added to compensate for
 evaporation when  necessary.  Empirical adjustments were made to secure
 optimum functioning  of  the ditch.

During the first year (1966-67) of a comprehensive study of solid waste
management by the University of California under the sponsorship  of the
Bureau of Waste Management, USPHS, a bibliographic search was  conducted
and investigations were launched in socio-economic studies and in the
processes of incineration, pyrolysis, composting, treatment of wastes
as components of sewage, wet oxidation, and biological  fractionation.
Particular importance was attached to this latter method inasmuch as it
would provide a return to the natural equilibrium of recycling of wastes
through the activities of microorganisms.  Primary emphasis is placed
on the management of municipal solid wastes.  One hundred sixty-eight

During phase II (June 1967 to September 1968) of the intensive study
of solid waste disposal in the San Francisco Bay area emphasis continued
to be placed on the transportation and ultimate disposal of municipal
and industrial wastes.  Land spreading of animal  wastes, while not
unobjectionable, left them much less pressing a problem than municipal
and industrial wastes.

The economics and technology of five processes were treated extensively.
While animal wastes were considered only to the extent of observing
that chicken manure is an excellent source of the nitrogen required in
anaerobic digestion, the discussions are of transfer value in animal
waste studies.  The methods, with page citations for economics and

While fresh  manure  has  the best fertilizer value, it may be necessary
to store manure while the ground  is frozen or in crops.  For best nitro-

Liquid handling is not considered to be a satisfactory  long-range
solution for poultry waste disposal.  Fan-drying of manure in the
poultry shed with cleanout about every five days produced a semi-solid
(28-35 percent moisture) product which was easy to handle, had little

no great labor problems, and has some as yet unestablished value.  The
cost is about 1/3 $ per dozen eggs.

On the feedlots of the High Plains of Texas manure is usually allowed
to accumulate in place with removal occurring once or twice per year.
In the dry climate dehydration occurs with resulting cessation of
decomposition.  Precipitation restores the manure to essentially its
original condition thus creating a high pollution potential.  The report
considers quality and quantity of runoff in comparing laboratory deter-
minations with field results.

"The quantity of runoff from a wet manure pack is independent of its
depth.  Runoff quantity from dry manure is partially dependent on manure
depth", feedlot slope, and rainfall intensity.  The quality of feedlot
runoff is primarily a function of the moisture content of the manure,
the rainfall intensity, and the feedlot slope."

"Properly treated, animal wastes have been demonstrated to be a bene-

however, most investigators have been reluctant to really delve into
this area of research mainly for two reasons:  (1) the checks and

bic tank followed by aerobic tank.  Systems 4 and 5 are in-house:
oxidation ditches and deep pits.  System 6 involves separation of
wastes into liquid and solid components.  Systems 7, 8^ and 9 are

intercepted in retention ponds and kept out of streams by land spreading

Refeeding holds much promise.  Some problems remain to be investi-

Incineration and pyrolysis may provide solutions in some locations.

"Land disposal always will be a most important aspect of agricultural
solid waste disposal."

Solutions must have technical merit and must integrate into the  full

Agricultural Waste Research Needs
Proc. Conf. Agr. Waste in an Urban Environment  p. 218-220

Disposal must not be the sole research aim.  Biological resources
should be conserved and returned to nature by techniques other than
land spreading.  The best methods of doing so remain to be determined.
With composting, drying and dehydration, and incineration the volume
is reduced prior to returning the wastes to the soil.  Faster processes
and/or odor reduction are needed.

Cost analyses of the processes, reuse values, and potential markets need
to be explored.  The author states without amplification that "re-feeding
of animal wastes is the least desirable reuse technique."

Collection and Disposal of Farm Wastes

Abst:  McQ & B A-227; W71-04486

Practices in Northern Ireland are summarized.  "At present practically
all the slurry collected in the British Isles is disposal of by direct
application to the land after a relatively short, 1  to 13 weeks,
storage period."  The usual problems of odors, excessive nutrients in
areas over-loaded with manure, and potential health hazards are
discussed.  Earthworm kills by excessive applications of slurry have
been observed; in such cases, however, the reduction in earthworms
has proved to be temporary and a rapid increase to or beyond the
original  numbers occurs.

The advantages of oxidation ditches include odor reduction in buildings
and during transport and spreading.  The total  waste volume is reduced,
the manure is rendered unattractive to rodents  and insects, the winter
ventilation requirements are lowered, and the operation is simple.

Disadvantages include higher capital  and operation costs.   Down-time
can be catastrophic in that toxic gases can accumulate.  Major construc-
tion is required in adapting existing buildings for oxidation ditches.
Foaming can be a problem.

Design and operation are discussed.  Cost data  and a sample design are
included.  Final disposal must not be to a stream.  A lagoon and

The historical development and present (Feb. 1971) status  of larvi-
cides for control of fly species in domestic animal manures are
reviewed.  Addition of the larvicide as a feed  additive has the advan-
tages of relative simplicity of mixing a determinate amount into a
poultry ration or the concentrate portion of a  cattle ration, the
economy of avoiding manure spraying, and the potential for treating
droppings of cattle on range.  However, the compound must be palatable,
must have no detrimental effect on the animal to which it is fed, and
must leave no injurious residue in tissue, milk, or eggs.  "Few insec-
ticides have all the above characteristics."  Seek current information
before feeding any larvicide.

"The obvious answer to shrinking profit margins is volume production."
This leads to mechanization which requires confinement.  "The population
equivalent figures, so common in the popular press, only distort the
actual picture."  "Among the problems associated with a more sophis-
ticated disposal scheme is manure collection.   The collection of manure
from an open feedlot has not proved amenable to traditional solid
handling techniques. . .  Odor control technology has not kept pace with
technology in confinement livestock production."

Based on research in Wisconsin, the authors favor land spreading of
wastes subject to specified precautions.  "Lagoons are currently not
considered generally acceptable for farm waste disposal."  Among the
conclusions stated were that nutrient losses in surface runoff from
plots having manure applied in summer and incorporated into the soil
were less than those from check plots which received no manure.
Manure should be spread only when the ground is not frozen and should
be incorporated into the soil as soon as possible.  Facilities for
winter storage of manure would be required.

In fermenting cattle manure anaerobically, the pH drops from 6.25 to
4.0 within 16.5 hours when the manure is incubated at 37C.  By adjust-

may be raised from 16.99 percent to 43.26 percent and the ami no acids

Improved rations can be expected to produce a richer manure.  This may
be refed or the nutrient, antibiotic, and vitamin content may be
salvaged.  Livestock may well be raised in complete confinement with no
runoff.  Zoning with several miles of cropland, partly irrigated with
animal wastes, separating town and feedshed is to be anticipated.
"When land is at a premium, the Southwest may become the livestock
center of the United States."

Lagoons may well be replaced by digesters, with these latter being
warmed by burning the gas they generate.  "Work on today's problem

Biodegrading Poultry Excreta with House Fly Larvae:  The Concept and
     Equipment
USDA ARS 33-136  3 p.

The ability of house fly  larvae to biodegrade chicken manure into a
fertilizer or soil conditioner and a feed supplement is under study
at Beltsville.   "The house fly larvae were selected for testing because
they can develop in organic wastes.  Fly eggs placed on fresh waste
hatch within 24  hours, and the young larvae immediately begin feeding
and tunneling into the medium.  Then after 6-7 days the larvae migrate
to a drier site where they pupate."  Equipment adequate for the process
is described and illustrated diagramatically.  The excreta from 100,000
hens could produce between 500 and 1000 pounds of pupae daily.  Dried
pupae have been  shown by  CALVERT et al [1969-1017] to be a satisfactory
source of protein for growing chicks.

The biochemical transformations consist of two distinct steps:  acid
fermentation and methane fermentation.  The acid fermentation is an
essentially constant-BOD process.  Stabilization of the waste occurs
only with the release of methane.  Similarities to the operation of a
rumen are cited.  "The anaerobic lagoon system, has definite advantages
in terms of costs over many other wastewater treatment systems.
However, its application is not universal.  There are many wastewaters
that should not be treated by this system.  The toxicity problems
resulting from heavy metals, sulfides and ammonia are not easily
controlled in this system.  Also the odor associated with hydrogen
sulfide release may be unacceptable.  The effect of temperature on
methane fermentation must be considered."

Handling of farm wastes in the UK is usually by one of the following
methods:

     1.  Solid - Use bedding to absorb the liquid.  Store the wastes
in a pit (lined or unlined) six to nine months.  Spread on land
semiannually.

                                 A-157

-------
     2.  Semi Solid - Handle manure, without use of bedding or dilution
water, by use of a spreader.  Odors and muddy fields cause problems.

     3.  Liquid applied by tanker - Storage is required.

     4.  Organic irrigation - Liquid applied by spray nozzle.

There is a tendency to return to solid handling.  Temporary aeration of
slurries by use of blowers has promise of eliminating odors during
spreading.  Refeeding, wet oxidation, and incineration have long-range
potential.

Quality of runoff from a 12,000-head commercial cattle feedlot in a
pond and in a reservoir to which overflow from the pond could drain
through a two-mile grass-grown ditch are discussed and tabulated.
Extraneous drainage was diverted around the feedlot and comparisons
were possible with a second reservoir of approximately the same age,
size, and drainage basin area without feedlots on its watershed.

The concentration of organic matter, solids, and nutrients in the feed-
lot runoff was high, but variable.  The pond reduced sediment, BOD, and
COD by 80  to 90 percent.  The ditch had little additional effect.   Fish
kills in the reservoir were due primarily to low levels of dissolved
oxygen, though ammonia was a contributing factor.  Algal blooms supplied
oxygen during hours of high light intensity but created additional
oxygen demands at night and when the sky was overcast.

Despite the effective capacity which ruminants have for digesting the
cellulose and hemicellulose of plant walls, some 40 and 60 percent of
this potential energy source escapes digestion and appears in the
feces.  Laboratory studies have demonstrated that some chemical
treatments are effective in enhancing the digestibility of these
residues.  "Sodium hydroxide is by far the most economical for treat-
ment of fecal cell walls even if the hydrolysed fraction of the cell
wall  is not recovered or utilized in fermentation.  Separation of
the soluble fecal dry matter from cell walls orior to treatment with
sodium hydroxide is not necessary to obtain significant responses."

For conditions in Ontario where most feedlots contain 300 head or less

to remain the preferred method of handling animal  wastes.  Mechanical
aeration is considered to be an effective means of controlling odor.
"Other methods of farm waste disposal have been suggested including:
(a) composting with or without municipal garbage;  (b) incineration;
(c) disposal in sanitary landfills; (d) liquid waste treatment systems;
and (e) reuse as animal feed. . .limited technology and present agri-

Control of Water Pollution from Southwestern Cattle Feedlots

Abst:  W71-05412

Groundwater from a shallow aquifer constitutes the principal water
supply for the High Plains of West Texas.  To protect the aquifer from
possible contamination from feedlot runoff, laboratory and field tests
were conducted to determine the characteristics of the liquid and solid
portions of the wastes and of the runoff resulting from precipitation
on feedlots.  Agronomic studies explored the feasibility  of  employing
the runoff for crop irrigation.

The study concluded that quality of runoff is not materially affected
by ration fed or by quantity of precipitation, that treatment of runoff
by conventional methods is not feasible, that direct application of
undiluted runoff to crops is detrimental, that storage in unlined
ponds risks groundwater pollution, and that liquid handling systems
for cattle feedlot wastes are thus not feasible.

Pennsylvania alone uses 250,000-300,000 tons of solid waste per year
as a basic material for compost.  This consists of horse manure, mulch
hay and corncobs.  Some poultry litter is also added.  For a crop of
about 125 million pounds, the spent compost to be replaced weighs about
400,000 tons.  This compost can be processed to produce organic

The Dry  Deep Pit System
Poultry  Tribune 77: Apr.  p. 26, 28

Odors, flies, and nutrients in water courses are the typical  pollution
problems associated with poultry.  All can be eliminated by use of a
deep  (8  to 10 ft) pit under the poultry house if it is kept dry.
Install  and maintain a proper watering system.  Mechanical  ventilation
will  be  required for high-density chicken populations.  The pit may
never require cleaning.

Drying Manure Under  Cages

Drying depends on  rate of air movement, amount of moisture in the air
and to be  removed, and air temperature.  To aid in drying, open chicken
houses in  warm weather,  increase the exposure of droppings, and retain
a dry pad  of manure  after cleanout.

Continuous disposal of cattle wastes, without pretreatment, on irrigated
croplands and pastures of Southern California, has built up concentra-
tions of salt and N03~ in the soil.  The Chino-Corona Basin between
Riverside and Los Angeles carries 122,000 dairy cows in 40 sq mi.  The
manure load is about ten cows per acre whereas equilibrium can be main-
tained only below about three cows per acre.  A partial solution would
be to volatilize the ammonia before incorporating the manure into the
soil.

Soil Conservation Service design criteria involve the compliance with
Texas Water Quality Board regulations including the by-passing of inflow,
the trapping of outflow, and the ability to dewater the retention pond
without releasing water to streams or draws.  Site selection for feedlot,
detention ponds and spreading fields is of basic importance.  Standard

$170 Per Head  But It Pays!

Gypsy Hill Farms in Southern Illinois feeds cattle on open lots ($20
per head), in a three-wall confinement barn with sawdust and straw on
dirt ($35), and in a similar structure with slatted floors and an oxida-
tion ditch ($170 as installed, but $125 estimated if redone  with present
knowledge).  Summer performance is about the same for the three
installations.  The open lot and the dirt-floor barn have similar winter
performance, affected by mud.

Drainage from the oxidation ditch is to an anaerobic lagoon  26 ft deep,
100 ft in diameter.  Overflow is to a one-acre aerobic lagoon 34 inches
deep.

The owner plans to convert the dirt-floor barn by installing another
oxidation ditch.

Converting Organic Wastes to Oil
USDI Bur. of Mines Rpt. of Investigations 7560.   20 p.
Abst:  McQ & B E-133

"The Bureau of Mines is experimentally converting cellulose, the chief
constituent of organic solid waste, to a low-sulfur oil.   All types of
cellulosic wastes, including urban refuse, agricultural wastes, sewage
sludge, wood, lignih, and bovine manure have been converted to oil by
reaction with carbon monoxide and water at temperatures of 350 to 400C
and pressures near 4000 psig, and in the presence of various catalysts
and solvents.  Cellulose conversions of 90 percent and better (correspond-
ing to oil yields of 40 to 50 percent) have been obtained."

Experimental procedures are described and the effects of varying tem-
perature, pressure, and water content, and of using various solvents
and catalysts are discussed.  Continuous, rather than batch, operation
has been limited to solutions of sucrose to date.  Concurrently special
slurry feed pumps are being tested.

It is concluded that "a significant part of the energy demand of the
Nation can be obtained on a renewable basis by converting nearly every
kind of organic solid waste to a low-sulfur oil  by treatment under pres-
sure with carbon monoxide and water.  Methods for lowering carbon
monoxide consumption and for operating at lower pressures have been
found; these offer the- potential of low processing costs  for converting
cellulosic wastes to oil."

A two-pond system is advocated in which "settled liquor is drawn from
the deep section by a centrifugal pump and sprayed over the shallow
section to aerate it with inspirated air.   The overflow passes back over
a weir into the deeper section."  Effluent disposal  is to some convenient
point at least fifty yards from a watercourse.

Oxidation ditches are effective if properly maintained.  A sludge con-
taining barley husks and hair may block ditches used for pig manure.
"One use of this material could be as a replacement for horse manure
used by the mushroom industry, which is now in short supply."

Low-Volume, Surface-Layer Aeration - Conditioned Manure Storage

Long-term storage of manure is required in much of the dairy area  of
North America.  Since waste should be returned to the soil  before  plant-
ing or after harvest, and not on snow, mud, or frozen ground,  six  months'
storage capacity is commonly used.  A manure storage lagoon is described
in which the surface liquid layer is aerated to reduce odor and prevent
scum formation.  "The advantage of aerating only a surface  layer is  to
reduce operation cost, improve nutrient recovery and allow  reuse of
supernatant in the waste handling system."

For composting, a mixture of garbage and manure has better qualities

Offensive odors of poultry manure are caused by the accumulation of

A high-rate composter consisting of a reinforced-concrete horizontal

which required removal of frozen compost from the walls with chisels

Concluded, however, that 1) broiler manure can be composted outdoors
in a Canadian winter without auxiliary heat, 2) a forced aeration sys-
tem is essential for high-rate composting of broiler manure, 3) loading
should be daily (seven days per week), 4) the composter should be roofed
to avoid excessive wetting of the contents by rain, and 5) the addition
of a blending material, preferably ground garbage, to raise the carbon-
to-nitrogen ratio  well above its value of 14.3 for broiler manure would
be advantageous.

Effluent Discharge Guidelines and Animal  Waste Management Technology
Proc. Natl. Symp. on Animal  Waste Mgmt.   p.  69-83
Abst:  McQ & B C-338

Runoff from a feedlot is intermittent (caused by rain or snow melt)
and variable in quality.  Its characteristics are such, however,  that
it is inadmissible in a watercourse.  Lagoons are unlikely to be  a
lasting solution; their effluents are also unacceptable in streams.
Water quality standards will require "zero discharge", by which is
meant no direct runoff from feedlots or overflow from lagoons.  While
land spreading of manure and irrigation with effluent may introduce
some pollution, it is considered to be manageable in a stream.

Acceptable methods of handling animal wastes include land spreading,
use of oxidation ditches with land spreading of the effluent, barriered
landscape water renovation systems [ERICKSON, et al, 1972-1043],  compost-
ing, and "complete treatment."  Waste recycling holds much promise for

Since the intestinal microflora of domestic animals include many
bacterial species that are similar to those in man's intestine,  incor-
porating such antibiotics as tetracycline into animal  feeds may  result
in permanent drug resistant populations  in man because of transferable
drug resistance between similar genera.   These resistant organisms may

in man and his  domestic animals."

Such resistant  bacterial isolates were common in samples from solid

Evaluation of Beef Feedlot Waste Management Alternatives
Proc. ISLW  p. 66-69, 72
Abst:  McQ & B C-230

For alternative means of handling solid wastes or slurries from open
feedlots or confinement buildings of several designs, costs per head
are discussed and represented on diagrams.  Optimum choices depend  upon
number of cattle fed, days of operation per year, climate, feedlot
drainage area, length of haul of waste for final disposal, etc.  The
authors conclude that "a manure-irrigation system for handling slurry
and flushed wastes costs about half as much as other waste handling
methods."

carried or liquid flush methods applied to each.  Treatment and
ultimate disposal are each accorded a chapter.  The methods of ultimate
disposal discussed are land disposal, irrigation, evaporation, and
incineration.  Economic considerations govern the choice among the
non-polluting alternatives.  Incineration involves risk of air pollution.
Use of manure as a fuel is cited-as a "promising method,"

FDA approval, quoted pertinent references to them in the literature,
and ventured an opinion on  their prevalence and toxicity.   Pellet
binders, flavoring  agents,  and enzymes would appear to pose little
threat.  Antibiotics, arsenicals, and nitrofurans fed at low level as
growth adjuvants should be  carefully evaluated as possible pollutants;
more information is needed  than is presently available.  Antifungal
additives would appear  to be safe.  Medications for specific diseases
require analysis oh an  individual basis.

to change its characteristics, if the larvae could be harvested
efficiently, and if larvae or later stages could be used as protein
sources for chicks.

Experiments are described and an analysis of the composition of dried

process or biodegrade caged laying hen manure.  The degradation
removes obnoxious odor, reduces moisture and volume of the manure.
The larvae, after pupation, or emergence as adult flies, can be used

areas entails risks of severe salt damage.   The conclusions of the
first interim report [1969-1087] were reaffirmed and four additional
conclusions and recommendations were added:

     1.  With proper management and judicious timing, runoff from feed-
lots can be used to advantage for the irrigation of some field crops.

     2.  Cattle feedlot runoff should never be applied as a prep!ant
irrigation or as an irrigation treatment on seedling crops.

     3.  Feedlot runoff can have a beneficial effect on cotton and
bermuda grass.

     4.  Additional research on both runoff and solid waste disposal
is called for.

Disposal of Dairy Cattle Wastes by Aerobic Digestion

A combination of aerated lagoons and irrigation appears to be an
excellent method of disposal for dairy cattle wastes.  It is essentially
odorless; it provides a place to dispose of wastes at all times; it
provides for the returning of a large part of the nutrients to the land;
with proper management, it minimizes runoff; it lowers pollutional
characteristics; and it has moderate costs of installation, operation,
and labor.

Status of Dairy Cattle Waste Treatment and Management Research

DALE summarizes dairy operations.  In general, small herds with adequate
land holding for spreading exist.  Sanitarians tend to approve return to
the soil and to view oxidation ditches and aerated lagoons with suspicion.
Anaerobic lagoons are even less reputable.

Composting and drying have some advocates, especially in warm, arid
settings.  Direct irrigation is used in some places.  Pyrolysis and
incineration have received little consideration though they have the
advantages of "volume reduction and production of dry and innocuous
residue."  Direct recycling "has been accomplished by ANTHONY with some
relative good results.  At least it did not appear to be detrimental
to the dairy cows."

Other methods listed without comment or reference are:

     "1.  Making into building blocks with glass
      2.  Squeezing into oil
      3.  Using hydroponically to produce plants
      4.  Synthesizing into proteinaceous materials and other products
      5.  Transported by beetles to soil
      6.  Placing in landfills
      7.  Feeding fish
      8.  Growing algae
      9.  Producing methane and other gases.

Each method has some merits but most of them do not offer an economically
sound method for treatment, handling and disposal.  Of course, as the
size of operation increases, some of these methods may become more
feasible.  However, until that time, the direct or indirect return of
wastes to the soil  to support plant growth appears to be the more
feasible way to handle dairy cattle wastes."

The results of feedlot runoff reaching a farm pond and a reservoir were
disastrous to the biological populations due to oxygen exhaustion and

chemical compositions and populations of aquatic organisms following
several runoff events.  Their recommendations are

     "1.  Present volumes of rainfall runoff, draining to surface waters
from feedlots, should be significantly reduced.

      2.  Feedlot waste management practices which would reduce the
concentration of pollutants in rainfall runoff should be established.

      3.  In addition to considerations such as availability of feed,
animals, and markets, future establishment of feedlot operations should
require incorporation of geographical and topographical features which
are conducive to efficient control of wastes and runoff drainage.

      4.  Waste treatment methods should be developed and tested for
application to feedlot rainfall runoff which drains to surface waters."

For a small barnyard in east-central Ohio from which drainage to a creek

FELDMANN, H. F.
Pipeline Gas from Solid Wastes
AIChE, 69th Mtg., Paper 6d  18 p.

Among the potential advantages of converting municipal solid wastes
(MSW) into pipeline gas are that:  (1) the large metropolitan areas
generate the waste and require the gas, (2) garbage is in abundant
supply while gas is short, (3) MSW has the chemical composition to be
a good feed material for a pipeline gas plant and to have a negative
price, (4) the high value of pipeline gas justifies the capital ex-
penditures for plant, and (5) environmental gains would result from
converting solid waste to a much smaller volume of sterile residue
and a clean burning gas.

Garbage can be supplemented with manure to advantage.  "Conversion of
this manure [U. S. total production of 1.3 billion tons/yr (dry basis)]
to methane could supply the entire United States consumption of natural
gas (based on 1966 figures)!"

Think Disposal -- Not Control!
Beef 7: Apr.  p. 4-5

Dumas Cattle Feeders of Dumas, Texas, have developed a sound waste
handling system.  They divert inflow around the feedlot and drain the
feedlot to a lagoon in an abandoned quarry.  Water from the lagoon,
diluted by recaptured irrigation tailwater and whatever well water a
farmer wishes to add is used for irrigation.  When the lagoon is dry,
the solids are removed and sold for fertilizer.  By controlling the
cattle feed, the manure is free of weed seeds.

Proc. ISLW  p. 301-304

Broiler litter has traditionally been used as a fertilizer,  but its
value for this purpose does not justify the cost of handling.
"Possibly, a more economical approach to disposal of broiler litter
would be to use this waste as animal feed."

"Experiments were conducted to:  (a) develop a processing method(s)
that will destroy pathogenic organisms in broiler litter; (b)  study
the effect of sterilizing methods on the nutritional value of litter;
(c) study the variation in chemical composition of litter; (d) determine
the palatability of rations containing different proportions of broiler
litter and (e) assess the magnitude of pesticide residues in broiler
litter."

"Broiler litter can be rendered free of pathogenic organisms by heat
treatment.  There is no serious pesticide residue problem from feeding
broiler litter.  Perhaps, the only major area of research which needs
to be pursued before poultry litter is considered safe as a feed for
cattle and sheep is the problem of medicinal drug residues."

The major items associated with swine production are antibiotics,
arsenicals, copper, m'trofurans, sulfonamides, and hormones.  Little
information is available on the potential buildup of antibiotics in
plants fertilized with swine manure.  Arsenicals are commonly used
but pose little hazard since they are not an accumulative poison
except in rats and the margin of safety is quite high.  Copper is an
effective growth stimulant at beneficial levels, but is toxic at higher
levels; present knowledge is inadequate.  There is a void in infor-
mation on the uptake of excreted m'trofurans by plants, and possible
entry into animals.   Hormones would appear to pose few threats.

The objectives of the research reported are "to develop a process for

sawdust initially as a source of carbon to produce a valuable soil
amendment."  Laboratory studies of combinations of manure and sawdust
with carbon-to-nitrogen ratios of 25:1 to 40:1 found them to be nutri-
tionally balanced for microbial growth.  The compost has proven to be
a valuable soil conditioner.  Swine manure may also be composted satis-
factorily with sawdust although the mixture required a week to become
thermophilic as opposed to one to two days for the poultry manure.

Velocities of runoff should be reduced to permit settling.  This was
accomplished by a batch method utilizing a detention reservoir to trap
all flow until settling had occurred; the supernatant was then pumped
out.  Alternatively, a chain of porous dams accomplished the same
objective with continuous flow.  With either system basins must be
cleaned out and the sludge disposed of.  This appears to be more easily
accomplished with the chain of porous dams.

The Disposal of Agricultural Wastes

Basic British law on disposal is reviewed and methods of disposal are
discussed in some detail.  Disposal to land, particularly in England's
damp climate, risks runoff to streams, muddy conditions limiting
spreading, and storage problems caused by mud and freezing.  Discharge
to public sewers, particularly of supernatant, may often be economical.
It provides for point-source supervised return to streams.  "The
implications of this are examined in relation to the assessment of
charges for treatment, and the economics which may be effected by pre-
treatment on the farm."

"Anaerobic treatment has rarely been found to be commercially effective
in respect of farm wastes. . .   Whilst the methane gas production is of
value, BOD/solids reduction is practically and economically difficult.
Full anaerobic degradation of farm wastes as a possibility, is still
only at the research and development stage."

An almost closed system for the transport of manure could result from
the employment of screens for removal of coarser material from dairy
cattle slurry, with some liquid being returned for flushing and the
excess being used for irrigation.  Very concentrated slurries have
poor settling characteristics and form scum mats and sludges when flow
ceases.

Solids removed from the screen and allowed to drain did not develop an

Feedlots are a viable industry in arid lands.  The greatest threat they
pose to an arid environment is probably localized pollution of shallow
grouhdwater rather than runoff to surface streams.  "Treatment of
feed-lot wastes by lagooning or other methods is not normally required
in our region. .  .  Returning the manure to agricultural lands appears
to be the best solution to the problem, particularly if manure can be
thinly spread."

Problems envisioned with recycling are 1) cost, 2) possible disease
spread, and 3) effect on the animals.  Costs will  usually exceed
nutritive value; they may be less than alternative disposal.  Poultry
manure is not recommended because of risk of salmonellosis.  Questions
of build-up of drugs, hormones, and antibiotics remain unanswered.

Animal Waste Reuse May Ease Disposal Problems
Wallaces Farmer 96: 11 Sept.  p. 131

Recycling of manure for fertilizer or by refeeding deserves intensive
studies in economics, in disease potential, and in "carry-over"
effects of additives.  Solutions having least net cost will vary
from place to place and in time.  Salmonellosis in poultry litter is
typical of problems which may arise.  The effects of drugs, hormones,
and antibiotics on the health of the second animal and the potential
of build-up in the meat have not been fully evaluated.

Chemical analyses of soil following the incorporation of poultry litter
show that rather drastic changes occur.  These vary considerably from
one soil type to another.  Poultry litter is a valuable source of
potassium, but the supply may be so great as to inhibit germination
and growth.  Analyses of three soils under various loadings at desig-
nated time intervals are represented by charts.  In general, an
incubation period is needed before planting a crop.

Among the advantages of confined feeding are the elimination of
surface runoff, maintenance of fertilizer value of manure by protecting
it from sun and rain, and saving in labor in manure handling.   An
oxidation ditch under the barn helps eliminate odors, but may have
high operating costs and be subject to overloading and mechanical
failure.  Land spreading with incorporation of the manure into the soil
is effective.  Chemical control of odors may be perfected.

Improving Water Utilization Efficiency in Automatic Hydraulic Waste
     Removal
Proc. ISLW  p. 154-158

In an attempt to secure better matching of scour and transport capacity,
the authors reviewed the literature of sediment transport and studied
behavior of model and prototype gutters.  Animal behavior patterns are
important to the success of water-economizing flushing.  Hence, it was
recommended that funds be made available for short-term facility
evaluation and, perhaps, modification.

"Automatic hydraulic waste removal could reduce initial capital and
operating costs, provide a better livestock environment and cut waste
management costs.  With the current farm cost-price situation and

Glenn BRESSLER considers the deep pit to be the worst oossible "solution"
to poultry manure disposal.  When the day of cleanout finally arrives,
the sticky, odiferous mess will have lost its fertilizer value.  Liquid
handling pollutes large volumes of waters with resulting higher costs
for low-pollution disposal.  Two-stage drying, with the first stage
occurring in place and reducing the moisture content from 75 percent to
35 percent, is advocated.  Cost data are cited.

required for the effluent.  Cooperation with operators, state, and

Cost of Maintaining Specified Levels of Water Pollution Control for

On the Southern High Plains, runoff from feedlots can be spread on open
fields or diverted to playa lakes to be disposed of by evaporation.
Evaporation from ponded liquid manure tends to be much less than from
open water and risks of ground Water pollution occur.  Periods of
intense storms cause overflow.

Covered pens to exclude rainfall would increase the capital investment
in feedlots by a factor of three and would necessitate abandonment of
present lots.  Better efficiency and reduced cost of manure disposal,
however, should repay the added costs in about 45 months.

Disposal by dilution with fresh water and use for irrigation is advocated,

Droppings caught in a wet pit decompose anaerobically.  When spread,
they have a noxious odor and may pollute runoff.  Aeration or drying
followed by land disposal is feasible; treatment for disposal to
water is unrealistic.  Drying is feasible if a market exists for the
product.  Some nitrogen removal  can be accomplished in an oxidation
ditch.  "... determine overall rather than piecemeal solutions."

Animal Waste Management -- Problems and Potential  Solutions
Proc. Agr. and Pollution Seminar, Univ. of Ariz.   n.  1-17

After an introduction sketching the development of the problem of
animal wastes with its social and legal constraints,  LOEHR examined
treatment and disposal methods.  Liquid manure handling contaminates
more volume of material, but eases handling problems.   "The use of
aerobic systems is increasing to avoid the odor problems that can
occur with anaerobic holding tanks."  For solid waste  handling,
composting -- often of a combination of manure with sawdust, corncobs,
paner, or municipal refuse -- is technically feasible, but seldom
financially attractive.  Drying, dehydration, and  incineration
eliminate odors and flies and reduce the bulk to be disnosed of.
With inclusion of air pollution control devices, they  tend to be
expensive.  Land disposal with holding tanks and a plow-furrow-cover
or similar method of application will probably remain  the usual
pattern.

Waste disposal should be treated as one element in optimizing live-
stock production.

Oxidation ditches are used in livestock waste management to prevent
and control odor, save labor, and purify waste.  A further advantage
is the ease of incorporation in confinement housing.  Tests of an
oxidation ditch in a poultry house at Cornell, with the ditch stressed
to the maximum to determine limiting adequacy, showed it to be a
"reasonable alternative" method of handling poultry wastes.
Maintenance can be expected to be minimal but necessary.  The
effluent should receive land disposal with proper land and crop

After concluding that there is no profitable method of using livestock
manure and, thus, that low cost methods of waste disposal  were needed,
the authors studied the orderly disposal of wastes onto agricultural
land by the establishment of test plots at a feedlot at Pratt, Kansas,
designed to accomodate 33,000 head on 220 acres.

The objectives stated were to characterize the stormwater runoff from
a feedlot, to characterize the manure generated, and to determine the
influence of runoff and manure loading rates on soil and water charac-
teristics and on yield of corn.  It was concluded, on the basis of the
first year's tests, that "the ratio of land needed for disposal of
feedlot wastes to feedlot area will be determined ultimately by the
permissible accumulation of nitrogen and salts in the soil profile."

organic wastes and marginal land, it may now be feasible to produce
an abundance of beef without using human foodstuffs  the nature
of the ruminant stomach, the genetic flexibility of cattle, and the
worldwide acceptance of beef make this possible.

"2.  Beef may be produced on a large scale, at less than 5 i per
pound, by locating dry-lot breeding facilities and feedlots in and
around cities  at urban fringes and in city dumps -- even the
manure becomes a valuable resource for refeeding, fertilizing, or
producing electricity  a major source of economies are (1) close
proximity for all production inputs to minimize transport costs;
(2) nearness to cheap feeds (garbage); and (3) the production of
beef close to urban markets using devalued land.

"3.  Sufficient organic waste exists in most countries to feed an
abundance of beef -- waste vegetation, industry wastes, paper,
manure, and even sewage, when properly fed and supplemented, can
feed beef."

Requirements of the law on feedlot control are quoted and answers to
questions of interpretation are given.  In particular, for an accept-
able runoff system:  1. Prevent inflow to the lot by locating near a
topographic ridge and/or constructing diversion channels or dykes.
South to east slopes are preferred since they are warmer and they dry
faster.  2.  Divert all roof drainage away from the feedlot surface.
3.  Surround the feedlot with dykes to control runoff and prevent
inflow.  4.  Provide a settling channel or terrace; remove the
deposited solids during dry periods in summer.  5.  Catch the liquid
runoff in a pond with sufficient volume to permit of disposal by
irrigation.

An Assessment of Some Public Health Problems  Resulting from Feeding
     Poultry Litter to Animals. Microbiological  and Chemical Parameters
Poultry Sci. 50: 874-881
Abst:  McQ & B B-297

Summary by authors:  "The feeding of poultry  litter to cattle, sheep,
and swine has opened many questions of public health significance.
The present study was designed to examine (1) whether the heat
resistance of Salmonella and Arizona pathogens  in poultry litter was
similar to that expected for wet or dry heat, (2) whether heat treat-
ment of poultry litter would provide an effective barrier against
disease transmission, and (3) to determine levels of some medicinals,
pesticides, and ultraviolet-light-activated compounds in poultry litter.

"Results demonstrated that salmonella and Mxzona Sp. are not highly
resistant to heat in poultry litter of normal moisture content.   Thus
a heat process for their elimination may be feasible.  The fact that
salmonellae are more resistant to moist heat, however, than are
E. Coti eliminates the use of E. CoLL as an  indicator of the efficiency
of the heating process.

"With the exception of arsenic, the concentration of pesticides  and
medicinals present in the litters assayed in  this study were low.   It
is possible that levels higher than those reported here might be
present in poultry litter.  This possibility  and the unknown effect
of continuous exposure to low levels of pesticides and medicinals
suggest that the present ban on the interstate  shipment of poultry
litter for animal feed is warranted,"

Biological Conversion of Animal  Wastes to Nutrients
EPA Pbln. SW-5r.2, p. 73-74

Fly pupae convert "wet, pasty, odiferous" poultry manure into  an
inoffensive, granular product which retains most of  the  fertilizer
value of the manure.  The dried fly pupae contain sixty  percent
protein and furnish vitamins and minerals when used  in a chick diet,
An optimum crop of pupae has a weight of about two percent that of
the fresh manure.

Fly eggs were placed in fresh poultry manure at a number of different
concentrations, different temperatures, and different humidities in a
series of experiments at Colorado State University.   Optimum produc-
tion of pupae occurred with three g of fly eggs in 4000 g of manure at
27C and 41 percent relative humidity.  At two g eggs per 4000 g manure.
the larvae were significantly heavier.

Three feeding trials in which dried pupae and/or catabolized poultry
manure residue were used as protein components to replace soybean
meal and/or milo in chick starter diets are reported in detail.  The
dried pupae gave results which did not differ significantly from
those of the soybean meal.  The digested poultry manure was signifi-
cantly less desirable than the controls.

Subsurface Distribution of Nitrates Below Commercial  Cattle Feedlots,

Water Res. Bull. 7: 941-950

Core sampling under 80 commercial cattle feedlots ranging in age from
new to 35 years established that "infiltration of feedlot liquid waste
to the water table below feedyards is insignificant in most localities

Infiltration Rates and Groundwater Quality Beneath Cattle Feedlots,

A test drilling program under and near a number of cattle feedlots on
the Texas High Plains established that while concentrations of
ammoniacal, organic and nitrite nitrogens in feedlot runoff exceed
those in the groundwater of the Ogallala aauifer, the nitrate nitro-
gen in the runoff may often be less concentrated.  Infiltration
varies with soil  texture; the bottoms of piaya lakes may present an
effective barrier against contamination of groundwater.  Permeability
is often so low that feedlot effluent reaching the water table is
returned by wells close to the feedlot.  "No regional degradation of
the Ogallala groundwater is expected in the foreseeable future, only
degradation in specific localized areas."

Water Hyacinths to Further Treat Anaerobic Lagoon Effluent

Water hyacinths were successfully grown in Iowa in the summer in
dilute effluent from an anaerobic lagoon treating swine manure.
Evapotranspiration was 3.2 to 3.7 times that from a free water surface.
A production of 84 tons/acre (5 tons/acre dried weight) removed 500 lb/
acre of nitrogen, 82 percent of influent phosphorus, and 88 percent of
influent COD.  The effluent was suitable for discharge to many streams
and could be used on porous ground without difficulty from nitrogen
build-up.in groundwater.

"The economic feasibility and attractiveness of this system demands
that uses for the harvested plants be devised.   Limited use has been

municipal treatment would cost $100 to 200 in capital costs and $4-$7
per year for operating costs per head.

Feedlots in desert conditions are less subject to runoff with result-
ing stream pollution.  "The aim is no outflow, no seepage to ground-
water, and minimum sludge to dispose of, besides avoiding nuisance to
nearby dwellers."

For the conditions at the Imperial Valley Field Station (2-3 in. annual
rainfall, over 100 in. potential evaporation) the authors concluded that
about "60 percent of the organic matter (volatile solids) and 45 per-
cent of the nitrogen was removed by an anaerobic-aerobic manure treat-
ment system at a loading rate of 0.023 Ib organic matter per day per
cu ft.  A liquid surface of about 200 sq ft was sufficient to evapo-
rate the water in the waste from four beef animals.  Investigations of
manure movement, other aeration systems, and sludge handling are
necessary for further development of a satisfactory manure management
system for a desert climate."  Eight references are listed.

It is not feasible to treat swine wastes for release to streams.
Spreading is resorted to more for disposal  than for fertilizer value.
Systems of waste handling currently employed are:

     1.  Wastes from hogs on pasture (may be serious source of
pollution),

     2.  Handling solids (some bedding is required and dilution must
be minimized),

     3.  Slotted floors -- store and haul (should be incorporated in
soil  upon spreading to reduce odors and runoff),

Most lagoons reported upon have a low input volume and long retention

content of less than 0.4 percent and a BOD of 500-1000 ppm, lagoons
have been discouraged.  The paper reports on the first eight months
of a trial with an anaerobic lagoon followed by two aerobic lagoons
and ultimate disposal for pasture irrigation.  Results have shown

 Alternative methods, considered to be financially or otherwise

 Methods involving recycling and reuse are composting (very limited

 followed by filtering (costly, odorous, source of mosquito breeding),
 aerobic algae ponds (experimental to date, but very encouraging),
 refeeding manure (profitable but with potential  for disease

Performance of several groups of pigs on corn-soybean meal rations
with various percentages of the ration replaced by dried swine feces
(DSF) or dried poultry wastes (DPW) is discussed and tabulated.
Among the conclusions stated are that pigs will consume corn-soy
rations containing up to 22 percent of DSF at 90 ,to 95 percent of
full appetite, that rate and efficiency of gain are depressed if
DSF replaces all or most of the soybean meal, that incorporation of
DSF in the ration does not affect the flavor of the meat, and that
DPW is of somewhat less value in swine rations because it is lowin

To prevent odor, keep manure dry or keen it aerobic.  Design criteria

Role of Animal Wastes in Agricultural Land Runoff

Abst:  McQ & B E-086

"The natural pollution load on streams draining agricultural basins
free of farm animals can be appreciable during periods of rainfall and
runoff and should be taken into consideration in water quality
management."  Land spreading is an effective means of preventing
pollution; it should be combined with good soil and water conservation
practices.  Anaerobic lagoons are unsatisfactory as a sole means of
treatment in areas where rainfall exceeds evaporation.

Criteria tentatively recommended for land disposal practices include:
a) apply wastes uniformly; b) govern rate, time, and frequency of
application for maximum nutrient utilization by plants; c) select
disposal areas with low erosion potentials; d) do not apply waste on
grassed waterways or other drainage paths; and e) plow waste under on
barren fields.

"This report summarizes the findings of a two-year study undertaken
to investigate the importance of animal wastes in agricultural land
runoff" from twelve typical agricultural sites in North Carolina.

The natural pollution from land free of animal wastes can be
appreciable.  The soil provides natural treatment for animal wastes;
thus, land spreading can be effective in pollution abatement,
especially if precautions with respect to drainage are observed.
Anaerobic lagoons were unsatisfactory as a sole treatment in that
"the lagoons functioned mainly as traps, i. e., settling and retention
basins, and provided only a limited amount of treatment beyond that
experienced through sedimentation."  Effluents from the lagoons were
potent.

In general, the state of the art was found to be primitive.

Poultry manure as excreted contains about 25 percent solids.  Various
methods of sludge concentration may be used.  In particular, centri-
fugation with a force of 10,000 G (G being the force of gravity at
sea level) will remove all wash water and recover over 95 percent of
the initial solids.  The quantity of water remaining to be removed
by drying is thus reduced significantly.

Reporting on three years of operation of a plant in Germany, the
author concludes that the returns from the sale of dried manure may
exceed the cost of dehydration.  The end product is a powdery,
humus-like material used by florists, vineyardists, and home
gardeners.  Prices are too high for most crop applications.

The essential components of the drying plant are a rotary kiln, a
ventilator, and a cyclone.  Through careful reuse of waste heat and
recycling of flue gas precipitates the efficiency can be improved
significantly.  A properly designed and operated plant releases no
offensive odors.

Some seven million ducks per year are raised on 35 farms on eastern
Long Island.  Most of their 6-to-7 week life is spent on water which
is then treated in aerated lagoons, chlorinated, and released to be
used for recreation and for shellfish habitat.  The phosphorus
content being excessive, a study was made to find a procedure which
would minimize total treatment costs while meeting New York effluent
quality standards.  Operating costs, particularly chemicals and sludge
disposal, were found to be the most significant expenditures.
"Reduction of water usage by duck farms may be the most direct method
of reducing costs."

 Poultry Waste as a Feed
 Egg  Industry 4: June  p. 61-62

 The  major organic substances in poultry manure are listed under the
 headings "Derived from undigested food" and "Derived from metabolism."
 Only about fifteen percent of feed is undigested and a second use by
 chickens is unlikely to salvage much.  Vitamins B and K are produced,
 but  are available from other sources at little cost.  Uric acid
 contains nitrogen, but it is in a form which poultry cannot use.
 Poultry waste is considered to be poor poultry feed.  Ruminants can
 utilize the uric acid, however, and thus may profit from poultry
 wastes as a feed ingredient.

 Measurement of feedlot waste is complicated by variation in moisture
 content, mixing with soil, inclusion of bedding and spilled feed,
 and on-site decomposition.  "Settling basins or debris trans are
 used to retain solids transported by runoff on a feedlot."

 Runoff measurement, particularly for quality determination, is
 complicated by viscous flow and negligible settling in cold weather,
 by the existence of both bedloads and suspended loads, and by inter-
 ference with sediment content by many standard measuring devices.
 Parshall flumes and time-sequenced, rotating dipper, proportional

"Drying systems applied to animal wastes in agriculture often have
the following disadvantages:  high capital investment, high operating
cost, major air pollution hazard, doubtful value of dried product
and significant operating and maintenance problems.  These deficien-

weight reduction in the waste, and the production of a relatively
odorless and stable dry solid.  This paper describes a new drying
system which minimizes the disadvantages mentioned above.  It also
provides unique benefits that greatly enhance drying as an economic
manure treatment method."

The equipment and process are sketched schematically and described.
The manure is preformed into pellets and superheated steam is blown

A Land Recycling Liquid Manure System for a Large-Scale Confinement
     Operation in a Cold Climate
Proc. ISLW  p. 39-43
Abst:  McQ & B C-223

Manure recycling of the cattle and sheep portion of the Greenbelt
Farm facility of the Canada Department of Agriculture's Animal
Research Institute in the suburbs of Ottawa is described.  The ground
being frozen 2.5 months per year and the water table approaching
to within two to three feet of the ground surface, special precautions
in provision of storage and design of storage tanks were required.
Provision was made for one-to-two months storage of liquid manure
within the animal buildings, and for four-to-five month storage in
separate concrete tanks nearby.  Land disposal with an acceptable
maximum of 45 to 50 tons per acre by means of vacuum tank trucks
followed by a plow which covers the manure within seconds is described.
Possible modifications are under study.

"Recycling the waste for re-use minimizes the change in- the balance of
nature which in turn minimizes the potential for polluting the
environment."

"The solution to the problem is to return the solid waste to the land
in'sufficient amounts for near maximum production of crops without
waste of the animal feces resource."

"If runoff cannot be disposed of economically in humid areas, cattle
feeding will be forced westward to drier climates.  A long-range
balance between availability of feed grains and ease of runoff
disposal will likely be established."

Air pollution is considered to be the most serious problem associated
with feedlots.  Zoning may be a partial answer.

     (1972)

Laboratory and field testing of cattle feedlot runoff from concrete-
paved and dirt feedlots on different slopes, with and without cover,
with different cleaning programs, different stacking densities, and
with differences in the cattle feed ration are reported and analyzed.
A good survey of the literature (72 references cited) is included.
In addition, 13 other papers by the authors are listed.

Major conclusions, of which the applicability may in some cases be
restricted to feedlots in a similar climate, are:

     1.  The variations of conditions mentioned are of no real
significance from the standpoint of water quality control.

     2.  Treatment by conventional anaerobic or aerobic processes of
precipitation-induced feedlot runoff is, infeasible.

     3.  Concentration of pollutants from concrete-surfaced lots is
two to four times greater than that from dirt lots.

     4-  Quantity of waste is a direct function of the fraction of
roughage in the ration.

     5.  Treatment by aerobic composting is technically feasible.

     6.  Extreme caution must be exercised if runoff is used to
irrigate crops.  With proper timing, limited quantities may be
beneficially applied to most well-established crops.

     7.  Build up of Na+, Cl~, and other ions in the soil may result
from repeated applications of feedlot runoff.

and 37 acres of land were acquired and two lagoons followed by three
small holding vats were installed.  Effluent from the third vat
flows 250 ft in a boulder-strewn channel for further aeration.  BOD
reduction of 97 percent is obtained.  TS reduction is 32 percent at
10C, 89 percent at 20C, and 96 percent at 30C.  Discharge is to

however, as in portions of New York state, land spreading conflicts
with a predominant resort industry or a pressing suburbia other means
of waste disposal must be found.  "Processing of animal wastes by

     2.  Animal concentration, with attendant problems of waste
control and water pollution, is increasing.

     3.  In the 17 contiguous western states, cattle create more
pollution problems than sheep, swine, or poultry.

     4.  Potential pollution varies widely with precipitation,  land
slope, climate, and soil structure.

     5.  Pollution originating in animal feedlots may affect air and
water quality detrimentally in many ways.

     6.  Many feedlots do not meet present standards.

     7.  In low-rainfall areas relatively simple drainage and
storage provisions will prove to be adequate.

     8.  Opportunities may exist to use animal wastes for gas,  oil,

 Robert C. ALBIN, Texas Tech, found in a series of studies that the
 amount of manure produced by cattle increased markedly with the per-
 centage of roughage fed.  Crowding to below 40 sq ft per head led to
 lower daily weight gains, lower feed consumption, and lower efficiency

Process Converts Animal Wastes to Oil

The U. S. Bureau of Mines Division of Coal has been studying the
conversion of cellulosic wastes to oil.  Manure responds to the
process better than most wastes.  The process consists of placing
the waste in a reaction vessel with carbon monoxide at an initial
pressure of 1200 psi, heating to 380C, and then holding for 20

oil.  The oil is difficult to refine to gasoline, but makes an excellent
fuel oil.  The process is considered to be economically viable.

A Pollution Solution with Built-in Profits

The solution of the title is high-temperature drying to convert
poultry manure into a pathogen-free product suitable as an organic

techniques are loudly proclaiming that liquid manure handling systems
and even the latest rage  deep pits -- are as outdated as scrubbing
boards for doing home laundry.  This school of thought -- which is
drawing converts as fast as an old-fashioned revival meeting  says
dfty^ing jj> tk& ority way-  And the drying must be done quickly with
extremely high temperatures that pasteurize the product, reduce
volume of original manure down to one-third and  with an afterburner
eliminate all odor and emissions."  The article is developed under the

convenience and not on the basis of water purification."

Laboratory investigations of the effects of varying loading rates
and detention times are reported and published data are tabulated.
Tentative conclusions include "the implication tliat lagoons for
solids reduction efficiency should receive loading at rates less
than 12 Ib V. S./1000 ft3/day and lagoons for solids storage
efficiency should be loaded in excess of 12. . .  Longer detention
times could be expected to reduce the rate of sludge accumulation
and to increase the solids reduction rates found thus far in this
study."

Correlating Oil and Odorous Components in Stored Dairy Manure
ASAE Paper 72-950  17 p.

The odor intensity index (Oil) is defined as the number of dilutions
by one-half that are necessary to reduce the odor to a level that is

just detectable.  By means of odor panels, the authors sought corre-
lations of Oil with one or more of the components:  volatile
organic acids (VOA), ammonia (N^), and hydrogen sulfide (^S),
commonly present in liquid manure.  Six regression equations (in
the single variables, VOA with each of the others, and all  three
variables) were deduced.

Handling Mil king-Parlor Waste
Canadian Agr. Engrg. 14 (2): 56-58

Forced aeration of milking-parlor wastes, while producing a clari-
fied effluent much more acceptable than the raw wastes,, does not
produce an effluent acceptable for discharge to streams.   "Although
a septic tank system is quite capable of handling the volume of
waste from a milking parlor, it is unlikely that it can cope with
the high strength of, and wasted milk in, milking-parlor effluents."
A lagoon would have to be sized as an odor-controlling facility and
be pumped out periodically for land spreading.   "... where the
manure is already being handled as a liquid, the most satisfactory
alternative would appear to be combining the milking-parlor waste
with the manure. .  . the watery mil king-parlor waste would tend
to improve the handling characteristics of the manure."

Drying Poultry Manure and Refeeding the End Product
Proc. Cornell Agr. Waste Mgmt. Conf.  p.  289-293

Power costs for a dryer vary with moisture content desired,  but
should be about $6 to 8 per ton of dried  product.   Total  costs
range from $15 to 35 with the largest component often being  the
transportation of the manure from point of deposit to dryer.   The
quality of the end product depends on feed, method of drying,  and
promptness of drying.  Daily drying is preferable, and recycling
of dried manure with wet incoming manure  should be avoided'.

The optimum refeed level for laying hens  is 10 to  15 percent dried
poultry waste (DPW).  It may replace an equal  amount of corn.
"Fair to excellent" gains have been obtained by feeding cattle 25
percent DPW.

Dr. BETHEA reports on a literature survey on the chemical makeup of
odors and possible techniques for their control.  Parallels are cited
in the rendering industry.  He cites 52 references.

"The following methods of control as applied to excreta are discussed
in detail with comparative cost and effectiveness data:  odor
prevention by modification of feed rations; odor reduction by recycle
manure feeding and by improved waste handling procedures; odor
control by chemical reaction, ozonation, gas washing and scrubbing;
and odor elimination by thermal and catalytic oxidation."

The discussers, Thamon E. HAZEN (p. 771-772), and John L. MILLS and

Dehydrated Poultry Waste in Poultry Rations
Poultry Sci. 51: 1502-1511
Abst:  W73-03992

Dehydrated poultry waste, with less than ten percent moisture content,
was fed at levels of five to thirty percent to chicks, broiler stock,
and laying hens in rations calculated to be approximately isonitro-
genous (total N) and isocaloric.  When the DPW was included in a
well-balanced ration, no detrimental effect was observed on the health
of the birds.  Growth and feed efficiency decreased when the DPW

content was increased beyond ten percent.  The economics of the
over-all operation will require much study.  "Even if the poultry
industry had to subsidize the production of D.P.W. to make it
competitive with other ingredients, it would be justified, since
it would allow the poultry men to stay in business with fairly
odor-free premises and at the same time contribute to the improve-
ment of the 'quality1 of the environment."

were to develop design criteria to minimize pollution, facilitate
handling of wastes, and minimize costs consistent with effective
waste disposal.

Variations of open feedlots and confinement buildings are discussed

Air moving in the pit under a poultry house 24 hrs per day is
effective in removing moisture, thus in reducing odor and fly
problems and labor in cleaning the smaller volume of more-easily
handled manure which remains.  When cleaning, several inches of
dry manure should be left to absorb moisture.  The savings obtained

Feeding Poultry Manure to Animals
Feedstuffs 44: 31 July  p. 24-25, 27
Abst:  McQ & B F-106

In a good review of recent research, COUCH indicates that broiler
chicks could tolerate five percent of dehydrated poultry waste (DPW).
Growth decreased significantly when the percentage was raised to
ten and twenty due to low energy content.  No effect on egg taste or
storage quality was detectable when laying hens were fed ten, twenty,
or thirty percent DPW.

DPW was recycled in the same poultry through 14 cycles of 12 days
each in some tests.  At 12-1/2 percent no adverse effects appeared,
but at 25 percent the effects of the low energy content were clearly
present.  The age of manure at the time of drying is critical, and
the method of drying is important.  Manure for feed should be dried
daily.

Swine showed depressed feed conversion with as little as five percent
DPW.

Sheep can obtain up to fifty percent of their total nitrogen intake
from DPW without adverse effects.  Approximately forty nutritionists
agree unanimously that "the best place to use dehydrated poultry
waste was in beef cattle rations."

A bunker-type building with 11-foot walls made of 2-by-6 planking
stores manure in northern Wisconsin.  It was used two years before a
roof was added.  Two floor drains lead runoff to a detention pond
used as a source of irrigation water.  By adding manure only two or
three time per week during fly season, enough drying occurs to reduce
the fly problem.- The bunker has less odor than liquid manure, but
the solids when spread should be plowed or disced promptly.

In laboratory-scale investigations at Tuscaloosa, Alabama, it was

in a rotary kiln.  Weight reductions of as much as 90 percent and
volume reductions of 85 percent can be obtained.  The residue is
suitable as a potassium and phosphorus fertilizer and as a lime

This paper describes the pilot plant at the Richmond Field Station,
California, in which an integrated sanitation-waste material
recycling system which treats wastes, conserves water, and reclaims
directly the nutrients in the waste is being tested.  In an aerobic
phase algal activity or mechanical aeration could be used.  If algae
are grown a potential 30 to 40 tons (dry weight) of algae per acre of
pond per year can be obtained.  Algae can be'used as a portion of the
chicken feed with no noticeable effect of flavor or acceptability of
the eggs or on the weight, morbidity, or mortality of the birds.

Cost estimates for a prototype plant are in the range of 1-2  cents/
dozen eggs.

 Schematic diagrams and process data are included in the paper.

Nitrogen beyond the capacity of a crop to utilize it may pollute

it may be desired to conserve the nitrogen content of manure or to
reduce it drastically before spreading or irrigating.  Studies in the

described.

"From the limited data obtained in this study, the oxidation ditch
appears to be a useful device for controlling the ultimate nitrogen
content of the manure before land utilization.  By encouraging the
nitrification-denitrification sequence nitrogen can be removed and,
presumably, by inhibiting nitrification, nitrogen could be conserved.
Further studies are underway to determine the feasibility of nitri-
fication inhibition in the oxidation ditch."

A temperature range of 300 to 400C was used.  This resulted in
pressures of 2400 to 5300 psi.  The effect of using synthesis gas
(H2:CO = 0.9:1) or Ho in place of CO was investigated, as were
catalyst addition and vehicle.  Reasonably good oil yields were
obtained with the synthesis gas in place of CO.  Low operating
pressure and a reduced energy requirement for heating were achieved
through the use of a high-boiling vehicle and by reducing the
waterrmanure ratio to about 0.25:1.  Quantitative results are
tabulated showing percent conversion, percent oil yield, and CO
consumption as functions of temperature for each reactant gas
or H2-CO).  For example, with synthesis gas (^-CO), conversion was

Pyrolysis as a ftethod of Disposal of Cattle
Cornell Agr. Waste Mgmt. Conf.  p. 101-123
Feedlot Wastes
Following a general background on pyrolysis, particularly of wood,
the authors describe the procedures and discuss the results of tests
on three batches of steer manure from steers on different rations
and in different housing conditions.  Costs would vary with the
products sought, these being functions of temperature and pressure.

"The estimated cost/ton of pyrolysing manure (80% moisture) in a
feedlot of 40,000 head capacity is $5.60. . .  Details of the estimate
are presented. . .  Particular worthy of note is the fact that fuel
oil costs ($2.26/ton) are more than the value of recoverable tars
and oils ($1.29/ton)."

The economics of pyrolysis would improve if cattle were fed more
roughage (more and drier manure).  "Also, as oil and other fossil
sources of carbon become scarce, manure pyrolysate may become
competitive with crgde petroleum and coal tar."

"The pyrolysis process has its own environmental liabilities."

Operating costs run 80 i to $1.00 per animal marketed.  Effluent
and sludge must be disposed of.  In northern climates lagoons are
non-functional in winter.

 An Analysis of Beef Cattle Feedlot Designs for Pollution Control
 USDA ARS 42-201  8 p.

 The relative merits and costs of unpaved, paved, and housed feedlots
 are analyzed.  "High labor requirements for manure management and
 apparent cattle discomfort may limit development of outdoor paved
 lots.  .  .  There is little difference between the overall materials
 cost of paved and unpaved feedlots."  Use of an oxidation ditch
 increases  the initial costs of a housed feedlot by about 17 to 20
 percent.   Costs of electricity for operation are estimated at $17.50
 per head capacity.

 "Design of a runoff control facility for beef cattle feedlots should

 farming."  Experiments with batch and continuous runoff systems are
 described  and equations for the design of solids removal systems are

 Recycling can occur by 1) conversion to soil, 2) conversion to a feed-
 stuff directly or indirectly, and 3) conversion to useful chemicals
 by fermentation or by pyrolysis.

 Ponding, anaerobic and facultative, and its refinements -- the oxida-
 tion ditch, the high-rate pond, the trickling filter, and the acti-
 vated sludge process are discussed and evaluated.

Anaerobic digestion "is a rather expensive process to use for treating

Changing from Dumping to Recycling.  Part III:  Composting and

Compost Sci. 13: May-June  p. 5-7

"Composting is the biological decomposition of organic matter under
controlled conditions."  Consideration must be given to aeration,
moisture content, temperature, carbon-nitrogen ratio, and particle
size.  Manure can be composted in 8 to 14 days without undue difficulty,
A mixture of manure and sawdust or straw makes an excellent compost.

Land disposal may be employed directly if the assimilatory capacity
is not exceeded, or may by employed for the sludges produced by the
other methods.

Use of organic wastes in animal feedstuffs holds great promise
provided that the possibility of bacterial and viral transmission is
thoroughly explored, that the concentration of toxic materials is
investigated, and that Food and Drug Administration approval is
secured.

Pyrolysis "is as yet in the research stage."

Assorted fermentations are under investigation.  "At present, the
economics of the processes are highly unfavorable."

Thermochemical Evaluation of Animal Waste Conversion processes
Paper, 72nd Mat!. Htg.  AIChE  21-24 May

On a dry basis cattle manure has a heat content of 4000 to 7500 Btu/lb.
That of coal is 12,500.

Thermochemical calculations for conversion of manure to methane gas,
oil, and synthesis gas are detailed.  On the basis of a manure output
of seven pounds of manure (dry) per day from 600,000 cattle, all
product streams would have values which total about $9000 per day.
The cattle population (600,000) chosen is that within fifteen miles of
a point near Hereford, Texas.

Methane gas production would require oxygen costing $4276 per day on
the basis of the authors' price assumptions.  "As gas prices increase,
this process may become feasible at some locations."  A considerable
amount of further development would be required to make oil production
which requires 380C temperatures and 6000 psig pressures -- economic-
ally feasible.  "The production of synthesis gas suitable for feed to
an ammonia plant appears to have the most promise at this time due to
the simplicity of the process and the value of the product."

In a broad survey of the causes and proposed cures  for rapid eutrophi-
cation of lakes in the Saskatchewan River Basin,  HAMMER observes
that "no particular problem exists with livestock on  the range.   If,
however, they are confined more and more in feedlots  in the name  of
efficiency and profitability, localized problems  exist."  He observes
that regulations on new feedlots are adequate to  control runoff and
suggests that existing lots be modified if necessary.

He objects to winter spreading of manure on frozen  fields followed by
washing into streams in the spring thaw.

"The aim of the current study was to measure  the  nutritive  value  of
solid residue collected from aerobically-maintained swine excrement
present in an oxidation ditch."  It was found to  have nutritive value

Animal Waste Reuse

A feedlot operator should have sufficient land available for land
spreading of his wastes.  They should not be spread on frozen ground
and should be plowed in as spread.  The law requires this in Sweden
and may here ultimately.

Tests with recycling have indicated that manure from cattle with high
grain rations was most effective.  Poultry litter gave fair results
but it is not recommended.  Much nutritional value remains in manure.

HODGETTS, Brian
Animal Wastes in the U.S.A.
Agriculture 79: 98-103

This survey of American practice by an Englishman observes that "land
spreading is still, of course, generally the cheapest, most efficient
and most popular means of disposing of animal  manures, but the economic
cost of doing this may in some cases be so high as to make the system
unattractive."

Aerobic treatment of liquid wastes has advantages; its problems are
foaming, sedimentation and high running costs.  Aerobic treatment of
solids by the  'Bressler' system (fan aeration in pits beneath cages)
involves high capital costs.  Composting is ineffective on poultry
manure alone and, thus, involves blending with some other waste source.

Anaerobic lagoons work admirably in the climate of Southern California
with lagoon water being recirculated for flushing.

Nutrient recycling and manure degrading with fly larvae are discussed.
Fly larvae hold great promise in that "the activities of the young lar-
vae aerate and successfully deodorize the manure in 2-3 days and remove
50 percent of its moisture.  The larvae are allowed to pupate and when
dried and ground the pupae may be used as a protein source for the
growing chick.  The remaining manure may be further dried or pelleted
and can be used as a soil conditioner or fertilizer, or even as a
feed for catfish.  The manure from 100,000 hens is expected to pro-
duce between 500 and 1000 Ib of pupae meal daily."

As a step toward establishing allowable rates of land aoplication,
the authors experimented with a single anaerobic lagoon with effluent
used for irrigation and with two anaerobic lagoons in series.  It
would appear that land application may often be limited by the content
of nitrogen, sodium, or copper.  Copper build-up from swine manure can

form of aerobic treatment of livestock wastes appears certain to be
used in the future in animal production enterprises.  Odor control
alone may be sufficient to make it a feasible operation."  An
oxidation ditch, in addition to providing a nearly odorless operation,
has the ability to handle shock loads, requires little attention or
maintenance, fits well under a slotted floor, and is reasonably
inexpensive.

The effluent may best be used for irrigation.

 Foam control methods presently used are the spraying with water jets
 to break the foam mechanically or the dilution with appropriate

Sodium Levels in Beef Cattle Finishing Rations as Related to Perfor-

Texas Tech University, Reports - 1972 - Killgore Beef Cattle Ctr.,

One-hundred-eight steers were divided equally into six treatments
with three replications of  six steers each and fed rations containing
1.0 percent, 0.5 percent, 0.25 percent, 0.125 percent, 0.0625 percent
and 0 percent salt (NaCl).  Animal performance was measured by 28-day
weights, feed consumption,  feed conversion by pens, and carcass
traits.  Sodium (Na) concentration and build-up in the solid waste was
measured periodically by sampling the feedlot with a coring device.
Sodium concentration in the rations was not significantly related to
average daily gain, feed intake, or carcass traits.  There was a

                                  A-301

-------
significantly poorer feed conversion at the 1.0 percent level, but
the effect was attributed to animal variations.  Data suggested that
Na content of feedstuffs in finishing rations provide sufficient
levels to meet requirements without supplemental sodium.  Sodium
concentration in the solid waste was linearly related to Na intake.
Levels of Na accumulation in the solid waste appeared to be suffi-
ciently low so as not to be harmful in run-off or to croplands if
applied at 10-15 tons per acre every 3-4 years.

Quantity and quality relations for rainfall and runoff from a 12,000-
head cattle feedlot at McKinney, Texas, were studied.  Normal
precipitation is 37 in/yr and class A pan evaporation is 70 to 80 in/yr.
Procedures and findings are discussed and tabulated.

Among conclusions reached were that detention in holding ponds reduced
dissolved solids concentrations by 90 percent and organic pollution
concentrations by 70 percent, accounted for in part by sedimentation
and in part by dilution by rainfall on the pond surface.  Bacterial
counts were higher a day after runoff than they were during the
runoff.  The quality was unfit for discharge to streams.

It was recommended that open, uncovered cattle feedlots be provided
with storage and diversion facilities to prevent runoff to water
courses.  Surface water should not be permitted to enter feedlots.
A series of ponds is desirable.  Effluent from the final pond should
be treated, perhaps by being spread on land by sprinklers.

This is a well organized and clearly presented guide setting forth
the basic considerations of site selection.  A well chosen example
of a site development without and with proper concern for pollution
control adds to the value of the presentation.  Points covered include
regulations with a listing of the responsible agencies in each state.
Spatial requirements for pens, runoff diversion and collection
structures, ultimate disposal areas, and buffer zones are discussed
and tentative formulae are proposed.  Topographic features desired
are 1) a minimum of land contributing runoff to the feedlot, 2) a
slope between two and six percent which will assure drainage without
risking erosion, 3) space with suitable slope and deep soils for
construction of runoff collection and storage facilities, 4) an area
for manure storage which will not contribute to surface or groundwaters,
5) a dry access route with gentle gradients, and 6) a runoff disposal
site with mild gradients well away from natural drainage areas.
Microclimates, soil and geologic structures, and social considerations
are other points discussed.

This paper outlines the various parts of the BSP Heat Treatment
System (Porteous Process) used in conditioning lean sludges so that
they can be easily dewatered.  A broad, rather than an in-depth,
coverage of the topic is given

The main operations of the process include sludge thickening, pressure
pumping to 250 psig for introduction to a reactor, direct steam
heating and agitation for 20 to 60 minutes, followed by depressuri-
zation and dewatering.  The process breaks down the gel structure of
the fine sludge particles so that bound water can be released.  A
general flowsheet is shown and discussed.  Capacities for the units
range from 200 to 9000 GPH.  Operating costs and installed equipment
costs are shown for capacities of 2000, 4000, 6000, and 9000 GPH.
Types of sludge applicable to the process are discussed.  Applications
of the process to industry are outlined and variations of equipment
are described.  An important consideration is that heat from the
process can be recovered by boilers to provide steam for the process.

Storage of Manure Solids by Forming Soil-Manure Pellets
Proc. Cornell Agr. Waste Mgmt. Conf.  p. 201-210

In employing hydraulic transport of manure it is advantageous to
remove coarse sediments by screening.  Storage is often necessary
while awaiting spreading.  To inhibit odor} moisture content and/or
pH may require adjustment.  Mixing with soil and lime and pelleting
can accomplish this and produce a material easily handled.  Experiments
for optimizing the mix of manure, soil, lime, and water are discussed.

A Review of Public and Private Livestock Waste Regulations
Proc. Cornell Agr. Waste Mgmt. Conf.  p. 61-69

Public regulation is generally by some state agency with water pollu-
tion and air pollution usually being under different agencies.  In
general, tolerance levels are established and a permit system is imposed.

Private regulation is by means of civil lawsuits alleging nuisance and
seeking injunction and/or damages.  Technicalities are defined and
distinguished  in the paper.  Means suggested for reducing the likeli-
hood of suits are rural zoning, prudent site selection, prior
operation, caution in entering contracts, good housekeeping, and
compliance with licensing laws.

Nonpoint Rural Sources of Water Pollution

"Animal wastes in confined areas are the most significant stream
pollution sources in rural areas of the state. . .  Within current
technology the most practical means for controlling, handling and
disposing of animal waste in a manner that will minimize stream
pollution involve 1) using a feed ration that will lessen the quantity
of waste and improve its treatability, 2) preventtng uncontrolled
feedlot runoff, 3) providing adequate waste storage facilities, and
4) maintaining a controlled program of waste disposal on the land
surface."

LOEHR, Raymond C.
Agricultural Runoff -- Characteristics and Control
ASCE Proc. 98: SA 909-925

Soil conservation practices are valuable in controlling pollution in
that runoff contains organic matter and chemicals as well as silt.
Manure is not a serious pollutant until it reaches surface or ground
water.   Confined housing, in reducing quantity of diluted manure,
reduces  pollution hazard.  The quality of feedlot runoff is sensitive
to the intensity of precipitation, the initial moisture of the manure,
and the  type of surface, but is not particularly sensitive to the
quantity of manure on the lot.

Typical  constituent analyses of feedlot runoff and empirical rainfall-
runoff relations are cited.

A rational program of pollution control for feedlots consists of using
dikes and levees to prevent inflow to the lots and to impound outflow
from the lots.  Roofs should have gutters, and the roof runoff should
be led outside the dikes.  Settling basins ahead of combinations of
lagoons, oxidation ponds and aerated systems are useful.  Evaporation
ponds should be used where applicable.  Land spreading of solids and
irrigation with liquids is advocated.  Incorporation of manure into the
soil after spreading and recovery of tailwater are advisable.  Avoid

Removal of Phosphorus from Liquid Animal Manure Wastes
Proc. Cornell Agr. Waste Mgmt. Conf.  p. 411-427

Phosphorus removal from effluents is desirable to control  algal growth.
In general, it would seem to be preferable to utilize the phosphorus-
removing properties of soil by spreading animal waste effluents on
land rather than to attempt chemical removal.  In a few cases,'such as
in disposal of duck wastes on Long Island, treatment may be resorted
to.  Laboratory studies indicate that the addition of lime or alum
may be effective with lime usually being the least costly.

Odor control for poultry manure can be accomplished by removing
moisture or aerating.  Tests run at Cornell on four systems produced
the ratings indicated on an odor scale in which ten is very offensive:
undercage oxidation ditch 1.1, diffused aeration (forced addition of
air to tank containing manure covered with water) 1.1, undercage
drying by forced air 3.7, and undercage drying by use of fins 4.4.
Costs per dozen eggs for the four methods are given as 2-4, 2.7-3.4,

A survey of 17 farms in the UK pointed up the importance of keeping
uncovered yard area to a minimum to avoid dilution of manure from
rainfall.  For effective scraping minimize the area involved, avoid
dilution, preserve straight lines, and avoid obstacles such as
columns.  For slurry storage take advantage of natural slopes, use
slopes above two percent in drains, and avoid straw and fodder
inclusion.  Irrigation or lagoonirig are recommended.

Manure is Food for Protein
Feedlot Mgmt. 14: Oct.  p. 18-22

The process developed by General Electric and being tested at Casa
Grande,  Arizona, feeds manure to a strain of thermophilic bacteria
which convert 1 Ib of manure into 1.5 Ib of protein.  The bacteria
will be harvested and dried to an odorless, tasteless powder which
will be used as a high-protein feed supplement for cattle and other
animals.

Cattle manure was a natural first choice for a test material because
of its ready availability, and the consideration that the pollution
control aspect would help secure acceptance of the concept.

The test facility will operate on manure from 64 head of cattle and
four horses.  "No problems are anticipated from the appetite
standpoint. . .  The organisms are plant life, the manure is their
source of energy, and it is the organisms that are harvested for
refeeding."

Cost studies and design criteria for a full-scale plant will be
obtained.

The authors report the measurement of the build-up of nitrate

at various rates, of cow manure slurry four inches under a sod cover.
The results are highly sensitive to weather, especially to tempera-

cation appears to be "in the range of 500 to 600 Ib of N per acre."

Windrow Composting of Swine Wastes
Proc. Cornell Agr. Waste Mgmt. Conf.  p. 159-172

Composting of swine manure was studied with the objectives of control-
ling odors, finding a rapid procedure, obtaining large volume
reduction, securing a useful end product, and avoiding attracting
flies and rodents.

Odors occurred on startup.  Increased frequency of turning reduced
the duration of odor production.  Adulteration of the manure with
compost or straw reduced both odor and time to stabilization.  The
volume reduction and the quality of the end product were independent
of the amount of mixing.  Composting is considered to be a satis-
factory solution to swine waste disposal in New Jersey.

Continuous flow would be preferable to batching, since it would
eliminate startup.  Daily mixing would be desirable.

Continuous Refuse Retort -- A Feasibility Investigation
Thesis.  MS in ChE, Texas Tech University  54 p.

Most pyrolysis tests reported have been made on municipal refuse,
oil  shale, or coal.  Operation has usually been by batch processes.
Midwest Research Institute and WHITE and TAIGANIDES [1971-1260] have
reported on tests pyrolysing livestock wastes.  "Midwest Research
Institute does not believe manure pyrolysis to be economically
feasible but they based this on an 80 percent moisture content and
a 65 percent thermal efficiency.  If the moisture content were
reduced by normal evaporation and the thermal efficiency increased,
pyrolysis could be economically feasible."

MASSIE reports on four tests in a six-inch diameter pilot retort
and concludes that "a retort ten feet in diameter could process
129 tons per day of cattle manure containing 29.1 percent moisture."

Further studies on the Texas Tech University retort are in progress.

Nutrients are tabulated for various manures and their use on land to
produce crops is mentioned.  Other uses of increasing interest are
the possible production of petroleum and as portions of the feed
ration.  The U. S. Bureau of Mines is investigating processes for
recovering up to three barrels of petroleum per ton of manure.  If
all manure were utilized this would provide one-half the U. S. needs
for petroleum.  Refeeding could use up to sixty percent of the wastes,

Control of water and air pollution can be attained at moderate cost
by good design, maintenance, and operation of collecting facilities.
Mounding of solids for composting, easy drainage, and provision of
windbreaks for cattle protection are recommended.

A Systems Approach to Cattle Feedlot Pollution Control
Paper, 72nd Natl. Mtg., AIChE  29 p.

Very simple and relatively low-cost solutions are available for the
problem of water pollution caused by cattle feedlots.  "Vastly more
complex and difficult problems to solve are the air pollution and
solid waste disposal problems resulting from conventional feedlot
operations."

"Farmers do not generally consider  it to be economically feasible
to use manure as fertilizer.  Hence, about the only option open to
most feedlot operators for disposal of solid waste is to provide a
large tract of land on which the waste can be stored more or less
indefinitely. . .  Veritable mountains of manure exist.  . . these
mountains are frequently ignited by spontaneous combustion, thereby
providing an additional significant source of air pollution."

A nearly ideal feedlot., that of the Green Valley Cattle  Company at
San Marcos, Texas, is described.  It has slotted floors  over pits
cleaned daily, is completely roofed, and provides for irrigation
by means of a 2000-gal capacity honeywagon equipped with chisels
which dispose of the manure below surface thus avoiding  the other-
wise inevitable odor and fly problems.

Turkeys are raised on open range after their first few weeks.
Drainage and retention facilities similar to those required for cattle

poultry manure by flushing the droppings through a grinding and
separation system and  thence through a settling tank.  The supernatant
flowed to an algae pond where oxygenation occurred through photo-
synthesis and/or aeration.  The algae oroduced in photosynthesis
were harvested by means of a continuous centrifuge and used as a
component in the chickens' diet.

"It is estimated that  the cost of operating a system involving photo-
synthesis could be as  much a two cents per dozen eggs.  The value of
recovered nitrogen was not included in this cost estimate, but could
be as much as three cents per dozen eggs where sunlight is adequate
and land inexpensive.  The cost of aeration without photosynthesis is
also estimated to be about two cents per dozen eggs."

Dried Poultry Waste As Feed
Poultry Digest 31: 248-249

In European practice poultry manure is dried at lower temperatures
and the exhaust gases are often run through an afterburner.  Both
practices reduce odors.

Drying costs of $6 to $37 per ton have been reported.  Protein con-
tents range from three to 30 percent with low protein content
accompanying high-temperature drying and drying of old manure.

                                 A-316

-------
The value of DPW in the poultry ration is about $18 per ton.  It may
be more valuable for ruminants than for poultry since ruminants can
convert urea as uric acid to body proteins.  Poultry can not.

In an experimental plant in Kiel, .Germany, undiluted liquid pig manure
is treated in a battery of three tanks in series.  Each tank has a
motor-driven impeller providing aeration.  Decomposition would require
lengthy, and uneconomic, aeration.  Some odor and considerable foam
occurs.  The fertilizer qualities of the effluent are somewhat better
than those of raw liquid manure.

Stream Pollution from Animal Production Units
WPCF Jnl. 44: 1536-1544

Analyses of quality of runoff from hog lagoons, of streams into which
animal manure had been dumped directly, of streams draining watersheds
on which land spreading had occurred, and of a stream draining agri-
cultural land free of livestock are reported.  All sites were  in
North Carolina.

It was concluded that anaerobic lagoons were unsatisfactory as a sole
treatment for swine wastes where precipitation exceeds evaporation.
The lagoons functioned mainly as traps with a limited amount of treat-
ment beyond sedimentation.  Direct dumping into streams causes
excessive pollution.  Land spreading, observing reasonable precautions,
is effective.  Natural pollution from agricultural land is often high
even in the absence of livestock.  The state of the art is indeed
primitive.  Meaningful tests are required.  At present total organic
carbon would appear to be the most meaningful single parameter for
quality of animal waste runoff.

Manure-Handling Capacity of Soils from a Microbiological  Point of View
CSAE Paper No. 72-210  18 p.
Abst:  McQ & B G-160

The criterion for handling capacity of a soil  may be taken to be "the
ability of the soil  microflora to assimilate waste without permitting
excessive leakage of nutrients and other undesirable components from
the system."  This ability is affected by temperature, moisture
content, degree of aeration, pH, and initial microbial population.
The components of most concern are carbon, phosphorus, nitrogen,
and pathogenic organisms.  Of these, nitrogen is usually the most
critical.  Due to the complexities of microbial  conversions of
nitrogen in mineralization, nitrification, and denitrification
generalizations are frequently erroneous and many contradictory
results have been reported in the literature.

Methane Recovery from Chicken Manure Digestion
WPCF Jnl. 44: 2349-2354

Tests on an experimental anaerobic digester for the production of
methane gas from chicken manure are reported.  Calculations indicate
that a 60,000-chicken unit would supply enough methane to be self-
sufficient in its total electricity requirement, but at a cost six
times that of its present supply.  Improved technology and the
impending shortage of natural gas should reduce the adverse cost/
benefit ratio.   "The incentive for development of methane production
as a poultry by-product will most certainly be great when poultry
emissions, odor, and wastewater are subjected to controls.  It is
recommended that preliminary designs of poultry production facilities
incorporating alternative types of pollution controls and total
energy systems fueled by anaerobic digestion of chicken manure be
performed."

Pyrolysis of Waste Materials from Urban and Rural Sources

-------
"Municipal, industrial, and agricultural  wastes can be converted to
gas, liquid, and solid fuels by pyrolysis.   These fuels can be
burned cleanly in contrast to the complex combustion of the raw
refuse.  The process is thermally self-sufficient, usually from the
gas produced.  Energy in the feed is almost all recovered in the
product, depending on the feed composition.  For municipal refuse,
typical recoveries are about 85%; they are even higher for more
selective feed stocks such as scrap tires or plastics.  Moisture in
the feed can affect the product distribution by reaction with the
hydrocarbons formed and by participation in the water gas shift
reaction.

"Typical waste materials that are available in large quantities and
have been pyrolyzed include scrap tires, municipal refuse, wood
waste, battery cases, sludge, and manure.  Properly designed units
should vent no offensive products to the environment.  Residue sent
to landfill would be sterile and, in most cases, would be only a
small fraction of the original volume.  Preliminary estimates indi-
cate that the cost will be considerably less than for disposal by
other means.

"Although there are still many unansv/ered questions, the data reported
here give an indication of the anticipated processing conditions and
the products recovered.  Some of the questions concern the yields that
would be obtained in a continuous plant operating at equilibrium
conditions, the control of moisture in the pyrolysis zone, and the
preferred design of the pyrolysis unit."

Dried poultry waste has a low energy content.  When used in a poultry
ration its value is primarily for phosphorus.  Viewed as a manure
disposal method it may be uneconomical since only a decreasing per-
centage of the total manure produced can be refed to the same flock.

Cattle Market Wastes
Water Poll. Control 71: 533-538  Disc. 538-539

Loads from cattle markets, including the results of washing down the
trucks, often find their way to municipal treatment plants in the UK.
The variations in loads attendant upon the short periods of operations
of the markets and the intractability of much of the manure and straw
to sewage-plant biological treatment are detrimental to good operation,

Bedding straw should be removed thoroughly before hosing down; high-
pressure low-volume jets should be employed; fine screens protected
by grates should be employed.  The paper lists 34 references.

Discussers suggested lagoons at the market with supernatant flowing
to the treatment plant, and oxidation ditches.

Recycling Animal Wastes as a Protein Source

This review, of which the typed manuscript is 48 pages long with the last
14 constituting a list of references, discusses the use of animal
waste as a protein source for various classes of farm animals relative
to the diversity of nitrogen compounds in animal waste and examines
some animal recycling systems for efficient utilization.  "Under the
large confinement systems (caged layer operations and beef-feed!ots),
collection is a minor oroblem and an incentive exists for considering
animal waste as a protein source."  Analyses of manure and litter
for various classes of nitrogen content are reported and the effec-
tiveness of these for ruminants and non-ruminants is discussed.

The literature on the feeding of caged poultry manure, beef feedlot
manure, poultry litter, swine manure, and dairy cattle manure is
reviewed in a manner similar to that in chapter V of this report.
Poultry litter is the preferred source of manure-based protein,  and
ruminants are able to make the most effective utilization of a manure
component in their diet. "Methods of handling and processing animal
waste for feeding can result in adverse effects on its chemical
composition and thus possibly on nutritive value."

Sampling of soil near Alberta feedlots and of the Oldman River and

feedlots may be exaggerated.  Immediately adjacent to the lots high
concentrations of nitrate nitrogen, available phosphorus, and potas-
sium are encountered but these drop off rapidly in soil and ground-
water within 400 feet.  "There was no measurable evidence of nitrate
pollution of the nearby surface waters."  A pollution potential is,

Animal Waste Management in Texas
Memo AENG 6, Agric. Ext. Serv. Texas A & M  10 p.  mimeo.

Beef feedlots account for 65 percent of the animal manure (dry weight
basis) in Texas.  Of the total tonnage, 70 percent is from lots which
do not contribute to surface runoff under storms of less than once-
in-25-years frequency.  Other lots are being upgraded toward this
goal.  Land disposal provides fertilizer and soil conditioning
benefits.  No salt build-up occurs with application rates below
300-900 tons/acre.  "To summarize, land disposal of solid beef
feedlot wastes at rates consistent with sound agronomic practice
gives benefit-cost ratios of about 2:1 or 3:1."  Other methods cited
are conversion to a protein source by thermonhilic bacteria (GE -
Casa Grande, Arizona), conversion to building materials by mixing
with glass and heating at atmospheric pressure to 300-400C (Montford
Greeley, Colorado), conversion to fuel oil at 300-400C and 3000-4000

psi, refeeding as a fermented mixture of manure and hay, and pyrolysis
with ammonia recovery.

Turkey feedlots contribute to water pollution.  It is usual in Texas
to move the pens rather than the manure, utilizing the fertilizer
value of the manure where it falls.

Caged layers produce a high-nitrogen waste.  Dehydration and refeeding
appear promising.  SWEETEN urges a cautious approach to this solution.

Broiler manure has value as a fertilizer and in cattle feed rations.

For dairy cattle and swine, liquid manure handling is usual.  Odor
problems arise.  Lagooning provides little economic return.  Slurry
irrigation by pipeline and spray nozzle or by storage pit and honey
wagon is recommended.

"A background in the chemistry of cellulose pyrolysis and hydro-

which cellulosic solid waste is used both to produce process hydro-

for conversion to oil is developed.  The theoretical yield of
hydrocarbon oil from cellulose is 35.7 wt%, or 2.47 bbl/ton at
0.810 sp gr.  An economic process will probably use a reaction medium
of cellulosics slurried in oil and will require a catalyst that
permits operations at pressures below 1000 psig.  The heating value
of refuse is approximately 5000 BTU/lb, on an as-is basis and
9000 BTU/lb on a moisture and ash-free (MAF) basis.  At present,
pyrolysis processes are capable of producing a tar (containing

Nitrogen should not be returned to the land in excess of crop use.

The Relationship Between Animal Waste and Water Quality
EPA  16 p + appendices

The Board held meetings in Colorado 26-29 Oct 71 and in Illinois and
Indiana 24-28 Jan 72 to hear testimony on the animal waste pollution
problem.  Field trips were combined with both meetings.  The paper
summarizes the hearings.  As a consequence of the meetings, the
Board presented ten recommendations to EPA.  That on uses of animal
wastes is:

     "The Board believes that recycling animal wastes back onto the
land is the best practical approach in most situations, particularly
for smaller operators, through the use of catchment basins, lagooning
systems, and/or solid waste handling techniques.  There are also
other possible uses which  should be given full consideration.
Testimony presented to the Board indicates that promising possibi-
lities exist in converting animal wastes into fuels such as oil or
gas, building materials, dry fertilizer, tires, etc., and in recycling
back into animal feeds.   [It is recommended] that the Environmental
Protection Agency give high priority to funding for research and
development projects which may develop practicable and safe alternate
uses for animal wastes."

Ensiling Characteristics of Mixtures of Various Feedstuffs and

Jnl. Animal Sci. 36: 208

Various products were tested for blending with manure from concentrate-
fed cattle in various proportions for the preparation of a cattle
ration.  These included silages, green chopped forage, cottonseed
hulls, peanut hulls, rice hulls, and almond hulls.  Data on initial
and final pH, concentrations in silage of dry matter, crude protein,
ash, and lactic acids are listed.  "Except for excess moisture
ensiling characteristics were generally good.  All hull mixtures
were less satisfactory in chemical  and physical properties than
mixtures made with silages or green chopped rye forage."

In the oral presentation of the paper it was emphasized that the
mixtures used must ferment rapidly to produce acids, preferably
lactic, at a pH of about four, and that if the pH shifts rapidly
toward neutrality in the feed trough, the product will have low
nutritive value.

"Since the dry-matter digestibility of manure is about 60% in the

should be evaluated and hygiene is important.  Refeeding is permitted
in England, but not in the Common Market Countries or the U.  S.

Results of rainfall-runoff measurements on a feedlot  at Bushland,
Texas, are reported.   For the storms monitored, runoff occurred
with a half-inch or more of precipitation and  was  a linear function
of the precipitation.  "After a  lot becomes wet, severe tromninq
creates many deep hoof depressions that can retain significant
amounts of rainfall.   Also, under a heavy stocking rate, the manure
pack is thick and has a very high water-holding capacity."

"The use of playas for impounding feedlot runoff insures that  runoff
will not enter streams, rivers,  or lakes. . .   Very little percolation
occurs through a playa. . .  The potential of  the  feedlot to pollute
the water table appears very slight when a playa is used as the
catchment area."

Feedlot runoff, properly diluted with other runoff or well water,

Ponds in California's Central Valley have been found to be highly

do not contaminate groundwater, and can be pumned for irrigation.
For this latter purpose, blending with other waste is advised.  Ponds

The Disposal of Cattle Feedlot Wastes by Pyrolysis

Even after having postulated that "the criterion for optimization
was the (fcec [italics supplied] of liquid organic compounds which
were produced as water-soluble and water-insoluble oils and tars"
rather than the value, of the resultant products -- liquid, gas,
and/or solid -- the report concluded that "economic pyrolysis might
be feasible if the fresh manure were allowed to dry in an arid
climate."  This, however, would allegedly defeat "the whole premise
of rapid manure disposal."  Moreover, manure pyrolysates, like
"coal tar, soot, and the fumes of broiling meat" are gratuitously
suspected of being carcinogenic.

Laboratory procedures and a computer program for determining an
optimal experimental design system are described.  Appendix D, by

Tentative conclusions on the use of manure  as fertilizer  on the  High
Plains of Texas are that about ten tons  per acre would appear to be
optimum.  Of the nutrients present in manure, only nitrogen is
particularly valuable in High Plains soils.  Excessive nitrogen  leads
to accumulations of ammonia in the soil  and nitrate accumulation in
forage plants.  "When manure is applied  to  the  soil surface,  water
management determines how much manure can be applied without
decreasing yields."

"The soluble-salt content of manure is high and must be considered
carefully when manure is used on cropland.  . .   Even moderate appli-
cations of manure may cause a high concentration of salts  in  the
seeding zone."

A species of Afro-Asian dung beetle, Ontkovkagtu gazela, introduced

manure-breeding flies that affect cattle.  Under optimum conditions,
a cow dropping can be broken down in 24 hours through the cooperative
efforts of about 50 conjugal pairs of beetles.  Onth.opka.guA appears
to be able to survive winter weather and droughts.  The beetle
operates by working beneath the manure, breaking it down and burying
it in underground tunnels.  Being a night flier, it is less subject
to such predators as cattle egrets, meadowlarks, toads, and wild
turkeys.  It is also less apt to become an intermediate host of
parasites than are day crawling insects.

The high-priority research needs in the animal feedlot program are
seen as being:

"(1)  The need to develop techniques for reprocessing and converting
animal wastes into a usable product.  Currently promising processes
include conversion to some type of fuel, feed or feed additive for
animals, or other by-product.

"(2)  The urgent need to make the current information on animal waste
management readily available for widespread use by governmental
agencies, the feeding industry, and researchers in the field.  . ."

The medium-priority needs consist of the control of ancillary
pollutants and nuisances and the optimization of land spreading
practices.

The 23  research projects which  the program has sponsored are
summarized.

 Engineering for a  Mushroom Farm
 AIChE Paper No. 32a-   Detroit,  6 June  8 p.  proc-

 Mushroom compost is based on horse manure.   For the farm  described
 (near Pittsburgh)  the manure is supplied by  local  racetracks  and  (in
 winter)  by  shipment from New Orleans.  A substitute compost can be
 made from chicken  manure.  The  compost is used but once.

Dehydrated Poultry Manure as a Crude Protein Supplement for Sheep
Proc. Md. Nutrit. Conf.  p. 35-44

Studies are reported in which digestibilities, intakes, and body-
weight gains are compared for wethers fed complete-pelleted diets
supplemented with soybean oil meal (SBOM) or dehydrated broiler
manure (DPM).  Since poultry feed generally includes arsenicals,
determinations were made of the amount of arsenic excreted by the
sheep, and of the distribution and depletion rates of arsenic
retained in various tissues after prolonged high-level  arsenic
feeding.  Results, which are tabulated and plotted, include findings
that "nitrogen from broiler manure supplemented diets was not sig-
nificantly less digestible than SBOM nitrogen and was retained  in
the sheep equally well."  While arsenic was detected in all tissues
tested, "withdrawal of arsenic from feed results in a rapid decrease
in tissue arsenic concentration."

Dehydrated Poultry Manure as a Crude Protein Supplement for Lactating
     Cows  (Abst)
Amer. Dairy Sci.  Assn., 68th Ann. Mtg., Pullman, Wash.  24-27 June.

A ration containing 32 percent dehydrated poultry manure (DPM) and a
conventional control ration, both formulated to contain 17 percent
crude protein were fed to lactating Hoi steins.  Cows on the DPM
consumed less corn silage and less concentrate dry matter, gained
less weight, and produced less milk.  "In spite of reduced milk
output, the economics of DPM feeding compare favorably to conven-
tional CP."  [Crude protein].

Future Developments in Feedlot Waste Management
Symp. on Animal Waste Mgmt., Bushland, Texas,  p. 43-50

In summarizing a symposium in which the major emphasis was on ferti-
lizer values of beef feedlot manure, SWEETEN observed that state
legislation in Texas provided for abatement of water pollution, and

                                  A-356

he discussed national legislation and anticipated EPA guidelines.
Other recycling methods cited were the GE thermophilic bacteria
studies, the Montford project for producing building materials
from anaerobically-digested manure and waste glass, and various
thermochemical processes.  He advised caution in adopting any
method other than "our present environmentally acceptable
alternative -- land disposal."  In regard to refeeding he wondered
"if we can generally afford to collect manure as frequently as
would be needed to preserve the feed value and whether cattle feeders
can afford to utilize a feedstuff which, on a large scale, exhibits
such wide variability in protein and ash content."

Animal Waste Management -- Can We Learn from Europe?

Some European countries require an applicant for a permit to show
adequate land for disposal.  Screening, chemical treatment to settle
solids, final filtration, and some treatments adequate to permit
discharge of effluents to streams exist.  Europe has been confronted
with agriculture in an ecology-conscious urban environment.

Converting Hydrocarbons to Protein Sources for Poultry Feeding

The subhead, '^apid development and acceptance of single cell pro-
teins may ease pressure on protein supplies and reduce industrial
pollution," summarizes the paper.  With proper precautions, yeast
may constitute as high as 20 percent of the diet for young chicks.
However, levels above 15 percent may result in sticky droppings
and encrusted litter.  On the whole, algae products have a low
protein quality and poor taste acceptance.  Since chicks have
notoriously poor taste selection, they may be fed algae as a
secondary protein source.

Feeders Scolded for Failing to Learn Their "Manure Economics"
Beef 9: Mar.  p. 43, 66

In a USDA-sponsored symposium at Bushland, Texas, Bob BLISS stated
that the disposal of liquid wastes and feedlot runoff in the High
Plains was relatively simple.  It can be caught in playa lakes and
then pumped to the fields.  Care should be exercised to capture tail'
water for repumping.  Solid wastes should be returned to the land.
Research to determine optimum supplemental fertilizer programs, and
salesmanship to encourage use by farmers were called for.   A barter
system in which the feedlot trades manure free of debris and with a
moisture content under 40 percent for ensilage, grain, or hay was
recommended.

How Much for Waste Disposal?

Cost data are tabulated for a confinement building with slatted floors
over a deep pit which is cleaned twice annually and for an open
feedlot with lagoons.  Both are located in Missouri.  Manure from the
pit is spread by honey wagon.  Effluent from the lagoons is pumped
for irrigation and the solids are removed and spread while the lagoons
are dry.  Costs are 60 $ to $1.40 per 100 Ib gain for the confinement
building and 40 i to $1.40 per 100 Ib gain for the open feedlot.

Increased vigilance on air and water pollution will be required to
prevent imposition of stricter regulation.  Refeeding is possible.
Beef manure contains from five to 25 percent crude protein and can be
fed to cattle unprocessed or in a fermented state.  Greater rates of
gain and feed conversion efficiencies have been obtained by feeding
fermented mixtures of fresh feedlot manure and roughage.  "From a
practical standpoint, however," SWEETEN is quoted as saying, "I
wonder if we can generally afford to collect manure as frequently
as would be needed to preserve the feed value and whether cattle
feeders can afford to utilize a feedstuff which, on a large scale,
exhibits such wide variability in protein and ash content."

Feed Recycling Showing Promise
CALF News v. 11, Jan.  p. 28, 29, 52

The operation of the Feed Recycling Company of Blythe, California,
in which manure is separated into fibrous material and a liquid con-
taining protein, is described.  "Each ton of manure from a convene
tional feedlot brings 400 pounds of protein. .  .  The fibers also
have economic value as a feedback for the cattle, or for the manu-
facture of char or as a fuel."  A unit capable of processing 100
tons of raw manure per day would"have a capital cost of about
$180,000 and an operating cost of not more than five dollars per ton.
The resulting protein and fats should return $600,000 per year.

Another Possible Process for Manure
CALF News v. 11, Jan.  p. 38

Texas Tech professors James E. HALLIGAN and Robert M. SWEAZY are
investigating the economic feasibility of obtaining synthesis gas
from cattle manure, then using the synthesis gas to produce anhydrous
ammonia for fertilizer.  At present, methane gas is used for this
process.  While it is possible to produce methane gas from manure,
several steps in the process can be eliminated by substituting
synthesis gas.

The manure from 600,000 feedlot cattle would be sufficient to produce
1000 tons of ammonia per day.

Hamilton-Standard's studies for the ARS on anaerobic digestion of
manure are described.  "... waste from 5,000 to 7,000 head of
cattle would yield enough methane gas to provide heat and electric
power to operate the process.  The protein feed [produced in the
process] would cost less than its estimated value."

"In the ARS contract studies, manure is slurried, heated and fed
continuously to a fermentation tank.  A mixture of microorganisms
converts it to methane, carbon dioxide, and solid residue, which is
dried as a feed ingredient."  The residue may also be coated with
resin and pressed into board or used as a nutrient for a fungus that
produces a fiber-digesting enzyme which may be used to improve the
digestibility of poultry feed.

In papers at the Animal Waste Management Symposium at Bush!and, Texas,

Another Recycling Venture
CALF News 11: Apr.  p. 15-16

The Hamilton-Standard process employs anaerobic fermentation in the
thermophilic temperature range to convert manure from beef cattle on
a high-concentrate ration to methane and "biomass."  The process is
stable and reliable under variations in input quality, heat, etc.
Advantages of the system include abilities to a) utilize very thick
waste concentrations, b) operate with high process loading rates and
small fermenter volumes, c) have low power requirements, and d)
generate its own fuel energy.  The process is able to double the

-------
crude protein contents of the manure and increase the amino acids
by a factor of four.  The dried biomass can replace soybean meal
and cottonseed meal in the ration.  Economic break-even appears to
be in the vicinity of 5000 to 7000 head.  Capital costs are 2/3,
and operating costs 1/2 those of aerobic processes.

Of the total nitrogen in DPW about one-third is in uric acid,
one-third appears as protein, and the other third is in peptides,

                              APPENDIX C

              THE UNITED STATES DEPARTMENT OF AGRICULTURE'S

             CURRENT RESEARCH INFORMATION SYSTEM (USDA CRIS)


It should come as no surprize that the USDA and, in particular, its
subdivision the Agricultural Research Service (ARS), has been in the
forefront of research on the problems of the utilization and disposal
of animal wastes.  Through the kind cooperation of Robert 6.  YECK,
National Program Staff, Agricultural Research Service, the compiler
of this bibliography secured the pertinent CRIS reports of the USDA
as of 13 Oct 1972.  These are abstracted in this appendix.

A CRIS report is a summary of research, normally consisting of one to
four typed pages, listing for each project the investigators, title,
location, performing organization, agency identification, starting
and terminal dates, and a serial number designation referred to as
the accession number.  Each report states the objectives of the
investigation and the approach proposed.  Progress reports, usually
for annual periods with the latest placed first, follow.  Publications
which have resulted during each period are listed in the progress
reports.  It should be emphasized that the progress reports may be
tentative in nature and must not be interpreted as definitive findings.

Several of the projects abstracted have been initiated too recently
for a progress report to have been issued.  They are, however,
included as indicating valuable sources of information.

Soil as a Biological Incinerator for Animal Manures and Solid Wastes
USDA CRIS Accession No. 0057044  1 p.

SPONSORING ORGANIZATION:  Cooperative State Research Service,
Minnesota

OBJECTIVES:  To "examine the feasibility of utilizing a small area
of soil as a solid waste disposal area."  Drainage waters will  be
collected and analysed, and the lysimeter soil will be examined for
accumulation and/or migration of clay, nitrates, phosphates, and
organic matter.

Integrated Control of Flies and the Role of Dung-Inhabitating Insects
     in Natural Recycling of Dung
USDA CRIS Accession No. 0011709  4 p.

SPONSORING ORGANIZATION:  Cooperative State Research Service,
California

OBJECTIVES:  To determine the role of insects in the natural  degra-
dation and recycling of animal wastes and to determine the best
management system to utilize the insect-degradable dung.

PROGRESS REPORT:  Cattle droppings in four pasture settings were
collected and the insects in them were studied.  Natural  enemies of
flies were given particular attention.  It was observed that "the
use of wood shavings to promote more rapid drying of droppings and
hence reduce fly breeding, does not accomplish the latter."

lagoons with irrigation systems in returning dairy cattle and swine
wastes to the land.

PROGRESS REPORT:  Irrigation from an aerated lagoon was an effective
means of disposal of dairy cattle wastes.  Studies of nitrogen
removal by aeration indicate that one-half the  total nitrogen in
dairy cattle manure may be lost in the form of  ammonia, and one-
third may be converted to nitrates and nitrites.   The harvesting
of microbial protein from cow manure may yield  a  product deficient
in only one essential  amino acid, methionine, which may be refed
as 18 percent of the diet and as one-half of the  supplemental
protein.

STEWART, B. A.
Disposal of Animal Wastes by Agricultural Practices in the Southern
     Plains
USDA CRIS Accession No- 0020803  2 p.

SPONSORING ORGANIZATION:  SWC Research Division, ARS

OBJECTIVES:  To determine the maximum quantity of manure that can be
applied without impairing crop production and to measure pollutants
moving through soil loaded at high rates.

PROGRESS REPORT:  Plots have been loaded with 0, 10, 30, 60, 120, and
240 tons of manure per acre.  Irrigation applied prior to seeding
diluted salts and ammonium concentrations to levels that did not
affect yields except at loadings of 120 and 240 tons/acre.  Nitrate
accumulated in the soil at loadings of 30 tons/acre and higher.
Pollution hazards exist unless the crop utilizes most of the applied
nitrogen.  Playa lakes may be a real asset to the feeding industry
due to their impermeable beds.  Further research on this subject
is required.

OBJECTIVES:  To determine the feasibility of disposing of animal
waste, by means of lagoons in the climatic conditions found in
Louisiana.

PROGRESS REPORT:  Lagoons have performed well on both poultry and
swine wastes.  In a four-year period 5224 hens had been housed over
an aerated lagoon; they had left 36,558 Ib (dry basis) of manure,
or 7 Ib/hen-year, without odor problems resulting.  Two swine lagoons,
based on 35 and 45 sq ft of surface per 100 Ib of hog, operated
continuously for four and five years with little sludge accumulation,
no cleaning, and no odors.  Other data are reported.
