【摘要】 铜是动物体内必不可少的微量元素,在畜禽日粮中添加高剂量铜(高铜)起到改善畜禽生产性能作用,但是,对畜禽产品安全及环境污染应引起高度重视,文章除对高铜在畜禽日粮中的作用外,对不同铜源的在畜禽日粮中的添加进行实验比较。对畜禽日粮中添加有机铜、铜氨基酸鳌合物在畜禽机体吸收、改善生产性能、有机铜、铜氨基酸鳌合物的排泄及环境污染进行综合研究。更多还原

【Abstract】 Copper is the necessary microelement for animal. High dose of copper could improve animal growth performance. But it would bring pollution in some degree. The role of high copper in daily feed was reviewed and the effects on absorbtion,growth performance,evacuating and polluting were compared for organic copper and amino acid chelated copper.更多还原
