氨基酸铜在猪生产中的研究与应用

高铜日粮在养猪生产中应用普遍,近些年来对于其危害的报道也比比皆是,氨基酸铜(主要包括复合氨基酸螯合铜、蛋氨酸铜、赖氨酸铜、甘氨酸铜)作为一种有机铜源,其生物利用率高、毒副作用小等特点已经受到国内外越来越多的学者的关注,并进行了大量的试验研究。作者主要综述了氨基酸铜的理化特性,生物学功能及作为一种无机铜的替代产品在养猪生产中的研究与应用。

The Research and Applications of the Copper Amino Acid Chelate in Pigs Production

The high-copper diets were applied universally in the production of pigs. Recently its harm was showed in many reports. As a kind of organic copper,the copper amino acid chelate (mainly includes copper amino acid chelate compound,copper methionine,copper lysine,copper glycine) had heigher bioavailability and smaller toxicity and these characteristics already received more and more scholars, attention from both the domestic and foreign, and massive research experiments had been carried on.This article mainly summarized the copper amino acid chelate physics and chemistry characteristics,the biology function,the research advance and the aplications of the copper amino acid chelate as one kind of substitution of inorganic copper used in the pigs production.
