Study Notes
Livestock and Poultry Waste Management
- Livestock and poultry waste can raise huge clouds of dust, and two possible solutions to reduce dust production are increasing animal density and careful sprinkling with water.
Anaerobic Decomposition of Manure
- Anaerobic decomposition of manure is a complex biological process that produces methane, a greenhouse gas that contributes to global warming.
- Ammonia is also produced, which can deposit on nearby water surfaces, contribute to acid rain, and cause odor problems.
Hydrogen Sulfide and Odor Problems
- Hydrogen sulfide is a toxic gas that contributes to odor problems, which are a major concern for nearby living populations.
- Building farms far away from houses is becoming difficult due to population increase.
Point Source vs Non-Point Source Pollution
- Point source (PS) pollution comes from a pipe or conveyance, while non-point source (NPS) pollution comes from an area and is not directly conveyed.
- Large livestock operations (> 1000 head) are point sources, while smaller enterprises and runoff from cropland are non-point sources.
Livestock Waste and Disease Transmission
- Livestock and poultry wastes contain organisms associated with the gastrointestinal tract, such as fecal coliform bacteria.
- Diseases transmissible from livestock to humans are called zoonoses.
Airborne Discharges from Livestock Waste
- Airborne discharges from livestock waste include dust, reduced gases from anaerobic decomposition, and odors, with odors being the greatest challenge.
- Dust issues arise when livestock are confined in feedlots in arid regions.
Course Objectives and Basic Concepts in Animal Wastes Products
- The course objectives include managing animal wastes in an environmentally responsible manner, highlighting the major impacts of improper waste management, and adopting measures for safe and sustainable animal production operations.
