Feeding 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 کاملEvaluation 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 کاملImpact of salinomycin on the intestinal microflora of broiler chickens
BACKGROUND The ionophoric coccidiostat salinomycin is widely used in chicken feed. In the near future the use of ionophore coccidiostats may be banned as has been the case for other antimicrobial growth promoters. This study was conducted to examine the effect of salinomycin on Campylobacter jejuni infection and on the composition of the caecal microflora in broiler chickens. METHODS An exper...
