List of Reports of Experiments Conducted July 1, 1966 - 24 December 31, 1968 in ------- INTRODUCTION The United States Atomic Energy Commission (AEC) on July 1, 1963, awarded a contract to the Southwestern Radiological Health Laboratory (SWRHL), U. S. Public Health Service (USPHS), to study the transport of i radioiodine from the environment to man by the air-forage-cow-miIk-man system. To initiate this study Bioenvironmental Research (BER) was established within SWRHL to develop field and laboratory research protocols. An experimental dairy farm was required in order to study the passage of radioiodine through the human food chain under field conditions. Criteria for the farm site were determined and in 1963 a site was selected in Area 15 of the Nevada Test Site (NTS), 110 miles north of SWRHL. The criteria are covered in a previous report ^ '. The history and status of the herd and facilities for the period May 22, 1964, to July 1, 1966, was presented in SWRHL Report No. 55r The animal husbandry methods, i.e., feeding methods, milking procedures, identification and record systems, experimental procedures, etc., are all covered in that report and will not be repeated. This report covers the period July 1, 1966} through December 31, 1968, and reports changes in the facilities or dairy practices and documents the milk production, reproduction, veterinary medicine, and experiments of this period. ------- FACILITIES AND EQUIPMENT The basic facilities were described in SWRHL Report No. 55r. There have been minor modifications and additions to the facilities made since that report as shown in Figure 1. The original floors of the milk room and milking parlor,of the Area 15 facility were unsatisfactory as they had inadequate slope to the drains and were too smooth and slippery. In-July of 1966, the floor drains were lowered five inches and the slope of the floor increased to approximately 1/2 inch per foot. The floors were then surfaced with an epoxy and silicone-sand mixture that is easy to clean and furnishes good traction for the cows. In August of 1966, an asphalt parking apron was laid on the north side of the milking barn. A concrete pad was poured on the south side of the building to furnish a foundation for a grain storage building and to provide a hard surfaced entry way for the cows. These changes have helped decrease the amount of soil blown or tracked into the building. Also in August of 1966, a 1,128-bushel capacity, circular steel grain storage building was erected on the concrete pad. It is used for storage of the grain concentrate, salt, mineral supplements, and other feed supplies. The holding pen was enlarged by removing the loading chute and extending the fence several feet to the south. Two head holders were incorporated in the south fence. Drainage was .Improved by lowering the floor drains and pouring a new drainage basin in the holding pen. Two acres, to the south of the complex, were fenced with an electrically charged single strand wire, providing a much larger exercise area for the ------- TRANSFORMER PAD.

The extra area aids in keeping the cows cleaner and there are fewer foot problems as the exercise keeps the hooves worn short. A concrete pad for 12 individual 9' X 9' experimental feeding pens was constructed during the summer of 1967. These pads provide drainage and are easily cleaned, however, some cows became lame after being maintained on them for several days. Most of the pens have since been surfaced with TarTarr^ which is manufactured by the Minnesota Mining and Manufacturing Company of St. Paul, Minnesota. No lameness has occurred on these new surfaces. A mobile self-contained field milking barn and sampling laboratory was designed in 1967. This 30' X 8' X 10' semi-van trailer contains a two- cow milking parlor, a combination work and sampling room, a 550-gallon water storage tank and a utility room. The trailer is a single axle, drop frame model constructed of aluminum and steel which is riveted and welded into a semi-monocoque unit. The construction contract was awarded to the Aluminum Body Corporation of Montebello, California. The trailer was delivered in November of 1967. With the growth of our farm facility, additional storage buildings were required to protect the machinery and equipment from the elements and to provide shop space for maintenance. Construction and installation of an adequate commercial building was estimated at $50,000 to $60,000. A survey of available surplus buildings was made and two 20' X 48' Quonset huts were located at Camp Desert Rock. REECo, the NTS support contractor to the AEC, was consulted and an extensive plan for modification was devised which would cost $36,000. To conserve costs, the Farm Support Section (FSS) personnel surveyed, leveled, and packed two pads for the buildings. On April 25, 1968, the buildings were moved to the farm in "as is" condition at a cost of $2,448.60. ------- FSS personnel then developed their own plans for conversion and consulted with Area 12 maintenance. The cost of the modifications of the buildings was approximately $5,000. This price included new doors, lights, power panels, repair of walls and ceilings, and installation of a 4" X 20' X 50' cement pad for the shop Quonset. To keep the modifi- cation cost this low, FSS personnel built the steel frames and double 4' X 8' metal entrance doors, cut and graded the area for the concrete pad, and removed the existing plywood floor and backfilled it with three inches of gravel, trenched the ground for the electric cable, installed the water lines, and built and installed all partitions, work benches, and shelves in the shop area. In July of 1968, three additional pens were constructed west of the hay shed. These were constructed of 6" X 6" posts, strung with cables under spring tension and are used to house the bull and to provide pens for experimental cows when they are handled as a group. Power outages, both scheduled and accidental, frequently occur in this area. As the water supply and milking equipment depend upon electricity, personnel were often forced to haul water, delay milking, or milk by hand. To prevent this, a s.tandby generator, with automatic controls, was installed during December of 1966. All wooden fence posts, mangers, and feed bunks are sprayed with linseed oil annually. This prevents deterioration from the excessive dryness and heat of the summer. FSS personnel provide normal preventive maintenance and repairs for the milking system. A factory representative conducts a complete survey annually to insure that the equipment is functioning properly. ------- ANIMAL HUSBANDRY A. Background As stated in SWRHL-55r, the original herd consisted of 17 grade Holstein cows purchased by the AEC in the spring of 1964. Eighteen registered Holstein cows were purchased from various sources during 1964 and 1965. Twelve animals were culled, sacrificed, transferred to other government agencies, or died so that the herd consisted of 12 registered and 11 grade animals as of June 30, 1966. Since that time five additional registered cows have been purchased and six animals have entered the milking string via our breeding and replacement program. Eight animals have died or been transferred so as of December 31, 1968, the herd consisted of 10 grade and 16 registered Holstein cows (see Appendix I). Of the'original 17 cows, 5 are still in the herd. The lactating herd and the bull are maintained at the Area 15 Farm while the dry cows, replacement heifers, and newborn calves and nurse cow are maintained at the Well 3 facilities '2'. The record-keeping system, identification system, and routine and experimental milking procedures were detailed in SWRHL-55r and remain unchanged. B. Nutrition The cows, like most dairy cows in the Great Basin states, are maintained in a dry lot. They are not allowed to graze on pasture or the range. All roughage is brought to them. The basic roughage is alfalfa hay. This is supplemented with fresh green chop during the growing season of April through October. ------- Both the hay and green chop are fed free choice and are placed in the mangers twice a day. Consumption of hay is 35-40 pounds (16-18 kg) per cow per day, and that of green chop is 60-65 pounds (28-30 kg) per cow per day. All of the green chop (rye in April, May, and June and alfalfa for the rest of the growing season) is harvested from the Area-15 crop lands. Although these lands also produce over 60 ton of hay annually *• , additional hay is required. This is purchased under contract from various local vendors. Samples of hay (both purchased and produced on the farm) are taken periodically. These are submitted to a commercial laboratory for analysis. (See Table 1 for selected nutritional ingredients.) As the hay produced in desert areas is consistently high in protein, it was decided to feed 14 percent protein supplement rather than the 16 percent fed previously.. The supplement is fed at each milking. Average consumption of this is 12 pounds (5.5 kg) per cow per day. However, the amount fed each cow is proportional to the level of milk production of the individual cow. Trace mineralized salt is fed free choice to all the dairy cows. As this geographical area is extremely low in phosphorous and high in calcium, a special high'phosphorous-low calcium mineral supple- ment is also given free choice. C. Reproduction The ideal reproductive cycle for a dairy cow is to produce a calf annually. She is bred from 50 to 70 days after calving, milked for 305 days and then rests for 60 days before calving. Our herd, like most commercial dairies, falls somewhat short of this ideal (see Appendix II). ------- Table 1.

During this reporting period, the average number of days open for each cow was 117 days. This extended open period probably results from failure to detect estrus (heat) as the average cow in the herd conceives after only 1.8 breedings. This problem is intensified during the summer months as the high temperatures seem to depress the sexual vigor of the cow. Also, many estrus periods occur during the evening hours when the cows are unattended so the heats are undetected. Heat will not be detected if it occurs during experimental periods when the cows are restrained in individual feeding pens. (R1 In order to aid the detection of cows in heat, Kamar* heat detectors are now placed on the rear quarters of eligible animals. When the cow enters into estrus she will stand for other cows to mount. The pressure from the brisket of the mounting animal turns the detector red. This color change requires three seconds of pressure and only an animal in estrus will allow herself to be mounted for this length of time. This system has aided tremendously in the detection of heats. If a truly anestrus animal is found (no heats detected for 3-4 months) she is treated with 50,000 international units of EstrovariarV^ which usually initiates a regular estrus cycle. It is intended that replacement heifers will enter the herd from our breeding program. (See Appendix III.) In order to improve the quality of the herd, semen from superior bulls is selected from the semen bank of the Cache Valley Breeding Association, Logan, Utah. The cows are then bred by artificial insemination. A registered Holstein bull (No. 70) is also used on first calf heifers> on cows that have failed to settle after two breedings and when the insemination technician is Kamar, Inc., Box 26, Steamboat Springs, Colorado 80477 2 Warren-Teed Pharmaceuticals, Inc., 582 West Goodale Street, Columbus, Ohio 10 ------- not available. It is planned to train another herdsman so that a trained technician will be available seven days a week. As of December 31, 1965, six heifers have entered the lactating herd through our breeding replacement program. Five of these have proven to be acceptable replacements. Since July 1, 1966, there have been 68 calves born in the herd (see Appendix IV). Of these calves, ten were stillborn or died shortly after birth. Two of the stillborn calves were premature twins, two from cows that were affected with parturient paresis prior to parturition, and three (one set of twins) from cows that suffered from prolonged dystocia. The other three were born in the evening hours during inclement weather and probably succumbed because of exposure before aid could be rendered. There were six sets of twins during this period. All surviving calves have been large, vigorous, and have shown excellent growth. There have been two abortions reported. The first occurred during the terminal stages of the life of Cow No. 5 who died from traumatic pericarditis. Cow No. 39 aborted in December 1968. No cause was deter- mined as the fetus could not be found. However, she was negative for brucellosis and was apparently in good health and showed no clinical signs of illness or disease. In January 1968, it was decided that male calves, freemartins (sterile female twin of a male), and crossbred calves were of no value to the program and were too costly to ;raise to an age where they could be transferred tc another agency. Since that date, these calves have been euthanized within a day or two of birth. Euthanization is performed, by the intravenous injection of sodium pentobarbital at the rate of 300 mg/10 pounds of body weight. 11 ------- In 1968, Cow No. 35 became a nymphomaniac because of the formation of a large cyst on the left ovary. The cow was treated with 2500 units of chorionic gonadotrophin intravenously on several occasions and the cyst was manually ruptured. It is hoped that this regime of treatment will return her to a normal estrus cycle. D. Production Between July 1, 1966 and December 31, 1968, there were 58 complete lactations recorded. The average length of .lactation was 272 days and 13,330 pounds of milk was the average production (see Appendix II). For the period of May 1964 to July 1, 1966, our average production was 12,385 pounds in 303 days. The average butterfat percentage was 3.4 percent for both periods with 439 pounds of butterfat per cow produced in-the ,1964-66 period and 449 pounds per cow produced in the 1966-68 period. Although these statistics indicate that the herd production has continued to improve it is likely that the herd is near its maximum level of production. Despite an average age of 7.5 'years, most of the cows are either under four years (four cows) or over eight years (seventeen cows) of age. Production is usually relatively low for both age groups as the period of maximum productivity is from 6-8 years of age. Also because of AEC regulations (see Appendix III), it is extremely difficult to dispose of inferior animals by placing them on the commercial market. As a result we are forced to keep animals that would be culled from the herd under commercial standards. The Holstein-Friesian Association of America reports the following production figures based on :a twice-a-day-miIking, 305-day, mature- equivalent average of all reported DHIA records, 1956-1959. 12 ------- Hoi steins Milk (Ibs) Butterfat (Ibs) Registered 12,560 . 460 Grade 11,567 424 The Washington County, Utah, Dairy Herd Improvement Report of November 1965 lists the following figures: Number of Herds 8 Cows per Herd 84 Average Ibs of Milk .....; 12,241 Average % of Fat 3.5 Average Ibs of Fat 433 It is apparent that the herd compares quite favorably to the milk production of other commercial dairy herds. Our production is now fairly constant throughout the year as is shown in Figures 2 and 3. The average production (Figure 2) was 46.5 pounds of milk, per cow, per da,y.,. The. tpta.1 production per month averaged 25,370 pounds. The butterfat content of the milk is directly affected by heredity, type of feed, sudden changes in diet and stage of lactation. The erratic results in the herd (Figure 4) are due, in part, to a large percentage of animals being on field test and on different types of feed; e.g., green chop and hay, green chop only, or hay only. However, the fluctuations in the herd butterfat values are not consistant from year to year when similar feeding and weather conditions prevail so other factors must be involved. Some of these factors may be delays in analysis or variations in the methodology used in performing the tests. Milk samples are collected from each cow on the 29th of the month and are delivered to the Virgin Valley Dairy Herd Improvement- Association fieldman on the 1st of the next month. The same fieldman performed the test for the last four years. The DHIA-recommended preservative, potassium dichromate, is added to the sample at time of collection. 13 ------- 25 JUL AUG SEP OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC 1966 1967 1968 Figure 2.

Monthly Average Butterfat Percentage of Herd 16 ------- VETERINARY MEDICINE As is true of most dairy herds, the most important health problems are concerned with breeding difficulties (discussed in the reproduction section, pages 7-1^, calving complications, and infections of the mammary glands (mastitis). Metabolic diseases and digestive upsets make up the bulk of the other health problems encountered. A. Calving Complications There have been six cases of dystocia that have been successfully resolved. Two cows have been lost because of calving complications. Cow No. 17 suffered a severe dislocation of the right hip while calving on August 22, 1968. As she showed no response to treatments, she was euthanized on August 31, 1968. Necropsy findings are reported in Appendix V. Cow No. 28 suffered from dystocia on June 6, 1968, when NTS activities caused her to be unattended for 24 hours. The calf was in a dorsal- posterior presentation with retained hind feet causing a hip lock that resulted in dystocia. The calf was delivered manually but had been dead for some time as there was epilation of the hair. These complications led to retained placenta and metritis. The cow also suffered from severe mastitis of the right fore and rear quarters. Despite intensive treatment the cow died on June 15, 1968. Cause of death was determined to be a septicemia from the mastitis and metritis which developed subsequent to the dystocia. There have been five cases of retained placenta. These are usually associated with dystocia and/or multiple births. Treatment is with intravenous injections of a purified oxytocin principle, the manual removal of the placental membranes, and the placement of medicated intrauterine boluses. All cases have responded. 17 ------- B. Mastitis The complexity of the etiology of this condition makes solution of the problem dependent upon (1) clinical diagnosis of the specific microblal agent involved, (2) correction of faulty managerial practices, and (3) judicious use of drug therapy. Methods for the detection of mastitis consist of physical, chemical, or microbiological tests applied to the udder or milk. Physical tests include palpation, observation of inflammation of the udder, visual examination of the milk by use of the strip cup. Prior to applying the milking machine, two to three free-flowing streams from each teat are squirted into the strip cup. An abnormal finding i.e., clumps, serum, blood, etc., is classified as mastitis. Chemical tests are limited to a monthly California Mastitis Test (CMT). If the test is positive, i.e., if the leukocyte count is above normal, the affected quarter is assumed to have mastitis. Microbiological tests per se are not done. However, antibiotic sensitivity tests are done if the affected quarter does not respond to standard treatment. All suspects are treated as cases of acute mastitis. As determined by sensitivity tests and prior history,' the antibiotic of choice is infused into the affected quarter following each milking for no less than six treatments. Additional treatment is given as indicated. This may include parenteral antibiotics, fluid therapy, diuretics, hormones and/or rumen stimulants, depending on the clinical response. Spread of mastitis from infected cows to healthy cows is reduced by using separate milking buckets, milking infected animals last, isolation of infected cows, prevention of spilling of infected milk on floors, disinfection of teat cups, and other methods usually employed in strict sanitation programs. When a cow with a history of mastitis is dried up, 30 cc of Furacirr- is infused into each quarter. This is repeated 4-6 weeks prior to Eaton Laboratories, Norwich, New Jersey. 18 ------- parturition. By following this method religiously, the incidence of mastitis has been reduced considerably. As shown in Figure 5, our incidence of mastitis is quite low with an average of 1.2 cases per month. The average percentage of our herd infected each day is .9 percent. (Incidence from May 1964 - June 1966 was 1..7 percent.) However, we'have had four serious episodes of mastitis, which either resulted in permanent damage to the lactating tissue of the mammary gland or in death, as in the case of Cow No. 29. (See Appendix VI.) The mastitis incidence in individual cows is related in Appendix VII. C. Metabolic and Digestive Conditions There are five cows (16, 44, 45, 46, and 84) that usually suffer from parturient paresis (milk fever) at parturition. The standard treatment of intravenous infusion of 500 cc calcium borogluconate, usually controls the problem. However, on September 15', 1966, Cow No. 24 was treated and apparently responded, but during the night she relapsed and was . dead when the livestock workers reported for work on the morning of , the 16th. As a prophylatic treatment, each cow, approaching parturition, is injected with 50 cc of Cal-Gly-Phos& , intramuscularly. This is ad- ministered every seven days until the cow calves. No dramatic decline in the incidence of parturient paresis has been noted, however, the severity of the condition seems to be lessened. There have been three cases of ketosis, all of which have been successfully treated with the standard corticosteroid and glucose therapy. H. C.

Percent of Mastitis Incidence in USPHS Dairy Herd by Cow Days per Month 20 ------- Tympanites (bloat) has occurred when cows are fed a large amount of fresh alfalfa green chop without a preliminary feeding of hay. All cases of bloat were successfully relieved by administering surface wetting agents and by bleeding off the rumen gas via a stomach tube. When the cows are on green chop, they are fed a bloat preventive containing poloxalene which has eliminated all bloating incidents. There was one case of traumatic gastritis (hardware disease) during this period. Cow No. 5 became sick in early March of 1967; despite . intensive therapy she expired on June 25, 1967. (See Appendix VIII for history and necropsy details.) Because prevention of traumatic gastritis is more important than the medical or surgical treatment of the condition, magnets are placed in the rumens of all the dairy cows. This, for the most part, prevents the penetration of metal particles through the rumen wall into the abdominal or thoracic cavities, In addition to this, there has been a concentrated effort to strip lots and mangers of any pieces of baling wire or other metal objects that could be ingested. Care 1s taken to prevent the placement of wire in the hay manger during feeding. Hay produced on the Area 15 Farm is baled with twine which eliminated another source of hardware. 21 ------- HERD PARTICIPATION IN USPHS EXPERIMENTS The USPHS Area 15 Experimental Farm and dairy herd are used, primarily, for the assessment of radioiodine uptake by dairy cows. There have 131 been four I controlled release experiments conducted at the farm between July 1, 1966 and December 31, 1968. Two of these experiments (SIP and HARE) consisted of dry aerosols of diatomaceous earth tagged 131 with I which was generated over growing forages. One, Rainout, 131 was a I hydrosol which was sprayed on a forage plot and one, MICE, 131 was a release of molecular I9. In addition to these controlled 131 releases, the dairy herd is used for I uptake studies from forages contaminated by the fallout from reactor effluent or Plowshare cratering events. Studies were conducted for one reactor run, Phoebus, and three Plowshare events, Cabriolet, Buggy, and Schooner. Basically the cows were handled the same for all of these experiments. Each cow is assigned a specific forage ration, which may be spread hay, baled hay, chopped baled hay, spread alfalfa green chop, fresh alfalfa green chop, or fresh sudan green chop. The cow is placed in an individual feeding pen and fed a definite weight of the forage on an assigned schedule. A sample of each feeding of forage is collected and submitted for gamma spectroscopy analysis. The amount of uneaten residue is also determined so that the total intake of each cow is known. The total production at each milking is determined and a milk sample is collected for gamma spectroscopy so that each cow's output in the milk is also determined. The standard operating procedures for conduct of dairy cow experiments are listed in SWRHL-55r. 131 In addition to these I feeding experiments, selected cows have been 131 administered I via capsules and then placed in metabolism stalls 131 where the I output in the urine and feces was also measured. The basic objective of these experiments is to provide data which will be used to develop a mathematical.model for the accurate prediction of 22 ------- the amounts of radioiodine whioh will appear in the milk of dairy cows at any specified time after exposure. The details, and results may be found in the technical report for each experiment as listed in Table 2. Appendix IX lists the cows by number and shows their participation in all experiments. Appendix X lists each experiment chronologically and shows the type of exposure of each participating cow. In addition to the above experiments, in August and September of 1966 the -USPHS dairy herd was utilized by Dr. Dewitt 6. Hazzard, Research Branch, Division of Radiological Health, Rockville, Maryland, to determine 134 the in vivo binding effect of various levels of verxite on Cs. The cows each received 0.2 yc of Cs in the afternoon grain for 18 days. Group I cows (5, 16, 21, and 43) received 1.8 pounds of verxite each morning for 23 days; Group II cows (2, 22, 28, and 46) received 1.2 pounds for the same period; Group III cows (12, 13, 18, and 41) received 0.6 pounds^ and Group IV cows (15, 19, 26, and 45) received no verxite. Results of this experiment were published in June 1967, (Vol 50, p. 992) Journal of Dairy Science. The title of the article was "Verxite Flakes T?d for in vivo Binding of Cs in Cows." Since little information is available concerning the uptake, secretion, and metabolism of the isotopes of tungsten, chromium, and iron, a pre- liminary study (Project Checkout) was designed. On January 20, 1967, an oral dose of 80 yCi 50Cr, 45.4 yCi 59Fe, and 608 yCi of 187W was given to Cow No. 43 via a gelatin capsule. Milk samples were collected at each milking for the next six days. Analysis indicated that Cr Was 59 not secreted in the milk; that Fe is secreted in trace amounts; and that W is secreted in the milk with an effective half life of 16 hours. 23 ------- Table 2.

Replacement Cows for the U. S. Public Health Service Dairy Herd 46 ------- INTRODUCTION To keep the herd at the necessary level of production, new cows must replace those that have served a useful purpose but are no longer within acceptable standards. We try to maintain a herd of 18 lac- tating cows. This number of animals can be cared for efficiently with the available staff and is large enough to provide an adequate number of cows per group for our experiments. In order to maintain this number of milking cows, it is necessary to have a herd of from 26 to 28 cows in various stages of pregnancy and lactation. New animals are required periodically to replace aged animals, animals lost through death, and animals whose mammary glands are damaged by injury or by infection. Commercial dairies usually replace one-sixth of the entire herd each year. ' The two major avenues of providing the required replacements are (1) to establish a breeding program and raise our replacement stock or (2) to purchase mature cows on the open market. This report discusses the advantages and disadvantages of the two different procedures. 47 ------- PURCHASE OF REPLACEMENTS The isolation of our research facilities makes the locating of suitable replacement animals extremely difficult and time.consuming. Eligible replacements are usually sold from herds because of some undesirable trait, i.e., low butterfat, poor temperament, difficult or. slow milkers, or because of some physical or metabolic anomaly that makes them prone to lameness, mastitis, milk fever, ketosis, etc. In other words, we are usually purchasing high-grade culls, as most producers are reluctant to sell the better cows. When we purchase cows that meet our standard criteria, transportation becomes a major problem. The animals must be trucked; and, in most cases, this involves a long distance through a desert environment. Since these animals are usually not acclimated to the desert envi- ronment, travel must be atf night in the summer or only during the cool part of the year. Adjustment to the new surroundings is usually slow. Initially, they show weight loss, inappetence, and declining milk production. These characteristics are .undesirable, as data collected during an experiment may not be a true reflection of what occurs in the normal cow. Infectious diseases can exist in any dairy herd—latent or actual. Brucellosis, leptospirosis, infectious bovine rhinotracheitis, tubercu- losis, vibriosis, and trichomoniasis are a few of the diseases that must be guarded against. Despite our precautions to prevent introducing an infectious condition into our herd, the potential still exists. t • ' • An advantage in purchasing an animal, though, is that through the study of her previous lactation records we can determine what type of produc- tion can be expected after she becomes adjusted to her environment. This, of course, is only true of animals purchased ;which have previous records available. 48 ------- RAISING REPLACEMENT HEIFERS Because of possible legal consequences, the AEC does not permit any animal that has been maintained on the NTS to enter commercial marketing avenues. This makes the disposal of surplus calves and cull cows extreme- ly difficult. They must either be euthanized or transferred to another U. S. Government agency. Transfers are expensive and time consuming. As a breeding program is necessary to maintain a dairy herd in full milk production, it seems logical to use the calves for replacement purposes rather than destroying them. Calves raised oh our farm are adjusted to the desert environment and are not greatly influenced by the stresses of the climate when they reach maturity. As time goes on, our herd will become very closely related genetically, and every animal should respond similarly to the same conditions. i Surplus milk is used to feed the calves for the first few months of , their lives so expensive milk replacements are not required. The mild desert climate and isolation of the area reduces health problems to a minimum and expensive housing is not required. During the first three years of our dairy's operation, i.e., from 1964 to 1967, we purchased our replacement cows from dairies in Northern Nevada. Since 1967 we have utilized our own registered Holstein heifers as replacements. Six heifers have entered our milking string and five have proven to be suitable replacements. A major disadvantage of raising replacement heifers is that we must wait 2-1/2 to 3 years before an animal can enter the herd. There is always the risk that after this long waiting period an animal will not be suitable. Through artificial insemination, at a nominal cost ($2.00 per breeding), sires can be selected which will improve the weak points of our herd; i.e., increase the butterfat per- centage, strengthen rear legs, etc. 49 ------- ECONOMICS In this area of the Southwest, the average price paid for registered first-calf heifers of good breeding is $450 to $500. A registered second-lactation cow, with a 305-day production record showing 3.5 percent butterfat and 15,000 pounds of milk, will cost at least.$600. To these basic prices must be added the time required to locate, examine, and select the animals and the transportation cost. Because of the supply and demand, these animals usually meet our minimum standards but are not equal to the average cow in our herd. The average cost of raising a heifer from date of birth to a first calf is approximately $300 to $360.'3' The high cost of labor on the NTS may raise the figure somewhat; but, in this climate, the health and housing costs are held to a minimum. Personnel who milk and care for the dairy cows also care for the calves so little extra labor expense is involved. SUMMARY AND CONCLUSION The scientific advantages of raising our replacment animals are: 1. All animals are genetically similar in the herd. 2. Animals have lived their entire lives in the environment. 3. All age groups are represented. 4. It is easier to maintain a relatively disease-free herd. The economic advantages of raising our replacement animals are: 1. Lower total cost. 2. Elimination of wasteful euthanasia of new calves—male calves can be utilized for terminal experiments, development of ; special surgical techniques, etc. 3. Eliminates the need for searching for replacements. 50 ------- The only clear-cut drawback of raising replacement heifers is the element of risk that a heifer will not be a satisfactory replacement after rais- ing her to three years of age. This risk should be small with the use of proven sires. The same risk exists when buying mature cows on the commercial market, especially when buying first-calf heifers. Under the conditions existing at the NTS and under our operating rules, replacement of cows in our dairy herd by raising calves born to our own cows is more feasible than buying cows on the commercial market.

She is resting on her sternum with her forelegs normally flexed. The rear legs are extended foreward along the sides of the body. Rear legs are at about a 30° angle from the body. (See sketch) There is a scanty reddish brown discharge from the vulva. PRIMARY INCISION: jhe cow is lying on her left side. A midline incision is made and the forelegs are reflected dorsally with the skin. Much yellow subcutaneous fat is present. There is an edematous area over the right jugular furrow. This area contains a gelatinous mass approximately 18 cm long x 6 cm wide x 3 cm deep. This lesion is probably the result (Continued on attached sheet) 67 ------- HISTORY (Continued) treated for possible parturient paresis or ketosis. She was given 500 cc Dextrosol (Norden) I.V.; 500 cc Calsem-D (Massengill) I.V.; 20 mg Azium (Schering) I.M.; and 900 cc Dilusol (Diamond) I.V. An unsuccessful attempt was made to remove the placenta. She was given 4 sulfa urea boluets intra- uterine and 10 cc Mycillin V, I.M. 25 Aug 67 - cow lifted with tractor - could not stand at all on rear legs. 28 Aug 67 - cow given 500 cc Am Bex (Corvel) I.V. and 500 cc C.P.M.(Cutter) I.V. Although cow continued bright, alert and had good appetite, she remained down. Her rear legs were extended forward in a frog like position. It was decided to euthanize her on 31 Aug 67. She was sacrificed at 9:15 with captive bolt pistol. PRIMARY INCISION (Continued) of a faulty intravenous injection. There are areas of bruising and edematous infiltration over the sternum, in front of the udder and over the hips. These are probably the result of slinging the cow while trying to get her on her feet. There are extensive bruises and edematous areas over the posterior portion of the hips, most probably caused by pressure necrosis resulting from the sitting position she assumed. MISCELLANEOUS (Continued) The head of the femur is pulled out of the acetabulum. The round ligament is completely severed. Musculature over the sternum has a cooked appearance, probably from pressure necrosis. 68 ------- DIGESTIVE SYSTEM: Liver is yellowish in color and rather friable. Rumen contains approxi- mately 35 liters of dry green ingesta. The reticulum is clean with no hardware, gravel or magnets found. The omasum is impacted. There are thin layers of very, very dry ingesta between the leaves. The abomasum contains approximately one liter of brownish fluid. Mucosa is normal. The intestinal tract contains scanty amounts of semi-fluid fecal matter. Mucosa is normal in appearance throughout its length. GENITO-URINARY SYSTEM: No lesions are observed in the kidneys or bladder. The uterus shows little involution and contains approximately 1 liter of brownish red putrid fluid. The cow has metritis from the retained placenta. RESPIRATORY SYSTEM: Lungs are normal with the exception of a few atelectatic lobules on the edge of the diaphragmatic lobes. The left cardiac lobe shows some atelectatic in- volvement. CARDIOVASCULAR SYSTEM: NO lesions observed. MISCELLANEOUS: /\s ^e medial muscles proxinal to the right stifle are reflected, a muscle mass, 5 cm in diameter, shows extensive necrosis for it's entire length. It has a cooked appearance. Another bundle of muscle approximately 6 cm in width has been torn loose from it's medial attachment at the right hip joint. Other adducting muscles show this same necrosis at their attachment on the pubis. The marginal cartlidge of the right acetabulum shows extensive necrosis.

Cow lying on her left side in corral. She is dragged into the Autopsy Room at 1510. There is an abraded area 3 cm in diameter anterior to the teat on the left rear quarter. PRIMARY INCISION: The cow is lying on her right side. A midline incision is made,and the left foreleg and left hind leg are reflected dorsally with the skin. Much yellow subcutaneous fat is present. The peritoneal cavity is incised, and the abdominal musculature is (see attached sheet) ft) ------- Continuation Sheet AHU-29-NTS-68 History: down and did not arise until 0830 hours. Her temperature was 104.4°. Examina- tion revealed that the ventral one-half of both rear quarters were cold and purple. She had a fetid diarrhea, was very uncomfortable, and seemed in pain. She was chomping her teeth and appeared very toxic. A diagnosis of gangrenous mastitis was made with a grave prognosis. Treatment began at 0930 hours—she was given 1,000 cc Polysol (Cutter) I. V., 500 cc Trisulfa (Ann Vet. Sup.) I. V., 10 cc Pyrahistine (Pitman-Moore) I. V., 20 cc A-H solution (Jen-Sal) Sub Q, 12 cc lomycin (Norden) I. M., 5 cc Dihydrostreptomycin (Burns) I. M., 10 cc Dihydrostreptomycin (Burns) Intramammary (RR & LR), and 2 squeeze sets Valsengel (Eaton) (RR & LR). The cow steadily declined,and death occurred at 1400 hours. Primary Incision: reflected dorsally. The omentum contains much yellow fat. The ribs are cut at the costal chondral junction and at the spine. The rib cage is then removed. 71 ------- DIGESTIVE SYSTEM: The rumen is full of bright green ingesta. It is very dry. The reticulum contains a magnet with a fine wire and iron filings adhered to it. No pene- tration is observed. The omasum is normal in appearance. The abomasum is filled with watery, fetid, greenish ingesta. The serosa is a dark red and shows a hemorrhagic enteritis. The intestines are gas filled and contain scanty amounts of yellow-greenish fetid fluid. The serosa is inflamed, and there are scattered areas of petechial hemorrhages throughout the length of the small and large intestines. GENITOURINARY SYSTEM; The uterus contains a normal female fetus of seven-month maturity. No lesions are observed in the kidneys or urinary bladder. The mammary gland, when incised, shows normal tissue and contents in the forequarters. The ventral one-half of the rear quarters is dark red, soft, pulpy, and has a putrid odor. Fluid contents are reddish white. The dorsal one-half of the rear quarters appears normal. There is a sharp line of demarcation between the gangrenous areas and the normal tissue. RESPIRATORY SYSTEM: The ventral tip of the left diaphragmatic lobe is emphysemic. All lobes of the right lung show hypostatic congestion. The right cardiac lobe is slightly adhered to the intermediate lobe. The bronchial lymph nodes appear normal. CARDIOVASCULAR SYSTEM: There is a slight adhesion between the diaphragm and the ventral tip of the pericardia! sac. No evidence of pericarditis observed. The left auricle shows diffuse subepicardial hemorrhages at its borders. Petechial subepicardial hemorrhages are found at the tip of the left ventricle. As the left ventricle is incised, diffuse subendothelial hemorrhage is revealed. The entire endathelial lining has a hemorrhage approximately 1 mm in depth between it and the myocardium. All lymph nodes observed appear within normal limits. MISCELLANEOUS: There are mucoid adhesions approximately 20 cm in diameter between the anterior lobe of the liver and the diaphragm and the reticulum. There are two small hernias in the diaphragm which are approximately 2 cm and 4 cm in diameter. These are located on the midline at the center of the diaphragm. A spherical mass of grossly normal liver tissue protrudes through each hernia. One mass is approximately 5 cm in diameter, and the other is 3 cm in diameter. Each mass is connected to the liver by ' is aPP™1mately -5 cm in diameter.

There is a small amount of blood tinged fluid flowing from the nares. Rigor mortis is present in the rear extremities but is no longer present in the front extremities. -The hair coat is very rough and hair is easily removed. No extensive tympanites is observed, There is edema of the submaxillary space, brisket and ventral portions of the neck. This condition had been observed several weeks prior to death. PRIMARY INCISION: Made on ventral midline. The skin and right front and rear legs are reflected dorsally. Clear fluid flows freely from the edematous areas of the brisket, submaxillary space • and neck. The subcutaneous tissues in these areas are infiltrated with fluid from a depth of 1" to 3". The thyroid is excised and weighed. The right lobe feels fibrous. Edematous gelatinous tracts are found throught the musculature of the hind leg. This 76 ------- HISTORY:(Continued) on 7 April 1967. When in good health she weighed 1300 Ibs. Weight at death was estimated at 850-900 Ibs. PRIMARY INCISION (Continued) musculature has a greenish cast and has a fetid odor indicating that death occurred several hours earlier. As the abdominal cavity is incised, clear blood tinged fluid escapes. It is estimated that the cavity contains at least 12 liters of this fluid. 77 ------- DIGESTIVE SYSTEM: The reticulum is adhered to the diaphragm. Rumen contains approximately one-half bushel of bright green ingesta. Search of reticulum revealed two magnets and two pieces of tie wire. This wire was very sharp but not penetrating at time of autopsy. Site of penetration could not be found. Omasum contains a scanty amount of green ingesta that was moist. Abomasum contains approximately 500 cc's of brown ingesta. Serosa of abomasum had started to slip. ^ENITO-URINARY SYSTlM-with 9as and contains scanty .amounts of ingesta. Extensive postmortem changes in the kidneys - were very pulpy. No adhesions, abscesses or hemorrhages observed. Uterus showed normal involution. RESPIRATORY SYSTEM: The ribs are cut with an axe at the vertebrae and at the costal -chrondral junction and removed. There are extensive adhesions between the rib cage and the right lungs. Small abscesses containing a greyish white creamy exudate are intermingled with the adhesions. The lower three-fourths of all lobes of the right lung appear as a swollen grey sac. Imprint of the ribs may be seen in this mass. As the mass is incised, thin pinkish grey, very fetid exudate flows from it. Large masses of a creamy white, fibrinous, tenacious exudate is intermingled with the fluid. Total amount of exudate is estimated to be 18 liters. The walls of this huge abscess are approximately 3 cm in thickness and contain no recognizable lung tissue. The dorsal portion of the right lung and the left lung are compressed from this abscess and showed interlobular emphysema. Left lung shows hypostatic congestion. It is estimated that the viable portion of the lung has been reduced by two-thirds or three-fourths. CARDIOVASCULAR SYSTEM: Pericardial sac was adhered to the diaphragm and to the rib cage. The pericardial sac was adhered very tightly to the heart and was pulled away with difficulty. Adhesions were fibrinous in nature and contained no abscesses. The heart was very flabby. Right ventricle and auricle were dilated. No valvular lesions were found. The spleen was swollen. When it was incised, bloody fluid flowed from it and left only the capsule. All parenchyma tous XMKgftlXKKKMIXOWXX tissue shows advanced autolysis with only interstitial tissue. MISCELLANEOUS: Pictures were taken of all lesions. The carcass showed advanced postmortem changes so few histopathology samples were taken. A swab of the lung exudate was taken and sent to the laboratory for isolation and identification.
