Bioavailability of Phosphorus in Two Cultivars of Pea for Broiler Chicks.
The aim was to determine the relative bioavailability of phosphorus (P) in peas for 21-day old broiler chickens using slope-ratio assay. One hundred and sixty eight male Ross 308 broiler chicks were divided into 42 groups 4 balanced for body weight and fed 7 diets in a completely randomized design (6 groups/diet) from day 1 to 21 of age. The diets were a corn-soybean meal basal diet, and the co...
متن کاملDetermination of bioavailable nitrogen and phosphorus from pelletized broiler litter
Improved methods for broiler chicken (Gallus gallus domesticus) litter utilization are needed to alleviate potential impacts of pollution around broiler production operations. Pelletization may constitute one improved method for handling broiler litter. The objective of this study was to determine the change in nutrient concentration from pelletizing broiler litter, and determine availability o...
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 کاملProspects for phosphorus recovery from poultry litter.
Land disposal of poultry litter is an environmental concern often associated to excess phosphorus (P) in soils and potential water pollution in regions with intense poultry production. Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new litter management alternatives are needed ...
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...
