Swine Production and Environmental Stewardship
Management of manure and other by products of livestock production is a complex environmental issue. Manure and
livestock by products can have both positive and negative environmental consequences. Manure can produce substantial
benefits and/or result in severe environmental degradation. The actual environmental result depends upon choices that
the producer makes.
The swine industry faces growing scrutiny of its environmental stewardship. The potential impact of an individual
operation on the environment varies with animal concentration, weather, terrain, soils, production and waste management
strategies, and numerous other conditions.
• What are your highest risk situations or practices for your livestock operation?
• Are you developing plans and investing resources to address the highest risk situations?
• Are you an environmental steward?
It is hoped that this pictorial review of management practices found in swine production will benefit you in identifying and
implementing best management practices and being an environmental steward.

Managing Storage
Manure and wastewater can be managed and stored to protect water
quality.
A lined lagoon with adequate storage capacity
protects ground and surface water.
Depth markers gauge wastewater levels and help
avoid capacity issues.
Well maintained earthen lagoon facilitates proper
operation and maintenance.
Improperly stored and managed wastewater could pollute surface or ground water.
Improperly managed manure and wastewater could Overflowing lagoon has exceeded its capacity.
negatively impact water quality.
Lack of proper operation and maintenance results in
a failed berm.

Land Application and Nutrient Management
• Properly applied manure is a valuable source of plant nutrients that improves the quality and
productivity of soils.
• A Nutrient Management Plan allows efficient use of nutrients and protects water quality.
Even field application by incorporation reduces runoff
and odor.
Creating and following nutrient management plans
could improve the quality of soils.
A calibrated tank spreads manure evenly.
Some application practices could cause problems.
Non-calibrated sprayers can result in excessive
application of manure.
Manure from spray irrigation applied directly to a
drainage ditch.
Application to saturated soils could result in runoff.

Public Perception
Well maintained swine facilities can be managed to benefit the
environment and improve public perception of the industry.
Grass filter strips protect surface water from manure
and wastewater application.
Waste deposited under the surface of a lagoon could
help reduce offensive odor.
A well maintained facility with sufficient acreage for
land application of manure.
Some practices could harm the environment and affect public opinion.
Poor lagoon border management could result in
stability, pest, and odor problems.
Undersized and poorly managed lagoon.
Poorly managed facilities could affect public opinion.

Swine Confinement Areas
Best Management Practices can be applied to swine confinement areas.
Well designed and maintained swine units.
Fly paper or index cards could be used to determine
insect population and density.
Slotted floors facilitate waste handling and the recycling
of wastewater.
Some practices should be avoided.
Poorly designed and maintained facility.
Lack of insect control leads to animal stress, could
increase the spread of disease and be a nuisance to
neighbors.
Spilled feed wastes money and increases nutrient
content of manure.

Other Practices
Management Practices showing a concern for environmental health and
safety.
Securing facilities prevents accidents, vandalism, and
is a biosecurity precaution.
Precision feed management and the addition of
phytase promotes animal health and nutrient
management.
Develop an emergency management system.
Testing soils helps determine nutrient levels and plan
for land application of manure.
Swine raised on pasture rotation system.
Testing manure promotes proper nutrient
management.
