Abstract

Optimising the supply of dietary phosphorus (P) to animals requires sound knowledge regarding the availability of P from feed raw materials. Different definitions of available P have been proposed and various approaches are in use to determine P availability. These differences make it difficult to compare published data and to compile comprehensive feeding tables for use in the industry. This is disadvantageous in regard to feeding costs and sustainable handling of the limited global phosphate reserves. Working Group No 2 (Nutrition) of the European Federation of Branches of WPSA has developed a standard protocol for determination of available P in broilers. It is based on precaecal P digestibility and the details of this proposed protocol are explained in the following paper. Unresolved questions in regard to the determination of available P are also addressed. Researchers are encouraged to implement this standard protocol in future P availability studies and to contribute to its further improvement.
