摘　　要：磷(P)是动物体内必需的矿物质元素,具有重要的生物学功能。但是,磷的过多又会造成浪费和环境污染。只有磷的真消化率才能够更准确、真实地反映动物对磷的消化吸收情况。因此准确测定内源磷的排泄量和准确测定磷真消化率已经变得至关重要。本文介绍了几种测定内源磷和磷真消化率评定方法。Phosphorus is an essential mineral element for animals,it has important biological function.Phosphorus would be wasted and environment would be polluted,if phosphorus in diet exceeded the requirement of animals.Only the true digestibility of phosphorus can reflect the case of phosphorus digestibility and absorption.So,Several methods about determination of the true digestibility of phosphorus were introduced.
