The determination of retainable phosphorus, relative biological availability, and relative biological value of phosphorus sources for broilers.
A 10- to 21-d chick bioassay was conducted to determine the absolute retention value (ARV) for 2 different defluorinated phosphates (DF-1 and DF-2) and a reagent grade dicalcium phosphate (DCP). The total and test P in excreta regressed on feed P levels were subjected to general straight-line (linear), 1-slope broken-line, 2-slope broken-line, and polynomial regression methods to find the best ...
متن کاملBiological availability of phosphorus in defluorinated phosphates with different phosphorus solubilities in neutral ammonium citrate for chicks and pigs.
Two experiments were conducted to assess the bioavailability of P in five sources of defluorinated phosphate (DFP) that differed in P solubility in neutral ammonium citrate (NAC). In Exp. 1, 384 2-d-old male chicks were fed a corn-cornstarch-dextrose-soybean meal basal diet (1.22% lysine, 1.00% Ca, .45% P) or the basal with .05 or .10% P from monosodium phosphate (MSP), or .10% P from DFP with ...

Phosphorus Losses in Runoff after Application of Litter from Broilers Fed High-Available Phosphorus Corn Feed
Recent efforts to reduce phosphorus (P) content of corn grain fed to poultry have led to the development of low-phytic-acid corn. Research is needed to evaluate the environmental impact of the application to cropland of manure from animals fed low-phytic-acid corn. The purpose of this research was to determine P losses in runoff from a bare Piedmont soil (cecil clay loam; clayey, kaolinitic, th...
