Dietary manipulation and litter amendments can substantially lower ammonia (NH3) emissions from poultry houses or manure storage. Recent lab and field studies involving laying hen and broiler manure from control or experimental diets showed a decrease (30-60%) in ammonia emissions for the experimental diets containing corn dried distillers grains with solubles (DDGS), a mixture of zeolite and gypsum (EcoCal), and enzyme production. A study to evaluate the effects of feeding diets containing different feed additives on NH3 emissions, laying-hen production performance, and economic returns has been conducted at the farm scale. In addition to dietary manipulation, repeated application of litter amendments provides a means to reduce ammonia production from broiler litter, thus improving air quality and reducing ammonia emissions. A study to evaluate the effects of repeated PLT application on NH3 emission from broiler chickens is being conducted using environmentally controlled chambers. Two different application rates and schedules are evaluated.
