摘要/Abstract

摘要： 综述了磷在反刍动物体内代谢及平衡调节过程,同时对内源磷排泄量和磷真消化率的主要评定方法和影响因素进行了探讨。

Abstract: This article has reviewed the phosphorus metabolism and phosphorus homeostasis in ruminants.There arethree main methods measuring the endogenous outputs and the true digestibility of phosphorus, including 32P radioisotope ,linear regression analysis technique and difference assay.Finally the influence of dry matter intake,phosphorus intake,thesecretion of salivary phosphorus and the absorption efficiency on the endogenous outputs and true digestibility of phosphorushas also discussed.

Key words: Phosphorusmetabolism, Endogenousphosphorus, Endogenousoutputs, Truedigestibility, Ruminants
