title: Availability of phosphorus from ammonium polyphosphate for growing chickens.
abstract: Phosphorus from ammonium polyphosphate was equivalent in availability to that of other phosphate sources commonly used in broiler rations, and it was more available than that from reagent-grade tricalcium phosphate. Two three-week experiments conducted with broiler chickens showed that growth rate, feed efficiency, viability, and bone calcification were improved to a similar extent by adding an equivalent increment of phosphorus from dicalcium phosphate, defluorinated phosphate, or ammonium polyphosphate. The results of these experiments suggest that ammonium polyphosphate may be a useful phosphorus supplement for practical poultry rations.
