Evaluation of Ammonia Emissions from Broiler Litter
Ammonia (NH3) emissions from poultry litter results in air pollution and can cause high levels of NH3 in poultry houses, which negatively impacts bird performance. The objectives of this study were to: (1) conduct a nitrogen (N) mass balance in broiler houses by measuring the N inputs (bedding, chicks, and feed) and N outputs (birds marketed, mortality, litter/cake, NH3 emissions, and nitrous o...
متن کاملBroiler Litter in Ruminant Diets -implications
Use of byproducts in ruminant diets can decrease production costs and increase total production. Chemical and physical characteristics of byproduct feedstuffs and animal nutrient requirements determine most appropriate means of use. Broiler litter is high in ruminally degraded crude protein and moderate to low in available energy concentration; therefore, most efficient use is as a crude protei...
متن کاملPhosphorus Dynamics in Broiler Litter-Amended Soils
Because land application of broiler litter is commonly made in the spring before cropping season and in the fall, it is essential to understand how environmental variations, such as temperature, affect the phosphorus (P) dynamics. A laboratory incubation study was conducted at Waste Management and Forage Research Unit, USDAARS with the objective of determining the effects of temperature and soi...
متن کاملFeeding Broiler Litter to Beef Cattle
an annual rate of 7 percent since 1986 with 371 million broilers produced in 1994. Broiler litter (mixture of poultry excreta, bedding material, wasted feed and feathers) is usually removed from the poultry houses on an annual basis. Because of its high nutrient content, poultry litter is usually applied to agricultural land as fertilizer with an economic value of $20 to $30/ton. Broiler litter...
متن کاملLaboratory and field evaluation of broiler litter nitrogen mineralization.
Two studies were conducted for this research. First, a laboratory incubation to quantify broiler litter N mineralization with the following treatments: two soil moisture regimes, constant at 60% water fill pore space (WFPS) and fluctuating (60-30% WFPS), three soil types, Brooksville silty clay loam, Ruston sandy loam from Mississippi, and Catlin silt loam from Illinois. Second, a field incubat...
