铬对家禽生长性能的影响及其分子机理研究

Research the effect of chromium on growth performance of poultry and its molecular mechanism

铬是动物体内的必需微量元素,是葡萄糖耐量因子(GTF)的重要组成部分。近年来,铬对肉鸡生长性能的影响及其分子机理方面的研究已有较大的进展,本文主要就铬的生物学功能、作用机理、在家禽上的应用及影响铬作用效果的因素等方面作一综述。

Chromium （Cr） is an essential trace element for animals, and it is a significant component of glucose tolerance factor （GTF）. In recent years, the research about chromium on the growth performance of broilers and its molecular mechanism had been made considerable progress. This article made a overview on the biological function, mechanism of chromium, its application in poultry and the factors that affected chromium effect.
