摘 要:有机微量元素是一种高效、安全、无残留、低污染的添加剂。由于无机微量元素存在性质不稳定、利用率低等缺点,近几年来人们开始关注有机微量元素的研究。目前国外已经有大量研究表明有机微量元素在一定程度上可以促进犊牛健康和免疫能力,利于后备母牛生长,提高泌乳奶牛免疫力和抗应激水平,改善产奶量和乳成分,对预防乳房炎和蹄病也起到有益作用。文章综述了有机微量元素在奶牛不同生理阶段中的作用,为其在奶牛养殖生产中更广泛的应用提供理论基础。Organic trace element was a kind of additives of high efficiency,safety,no residue and low pollution.As for unstable properties and low utilization rate of inorganic trace elements,the organic trace elements were began to pay attention to research in recent years.At present,a lot of studies at abroad have shown,organic trace elements can promote the health and immune ability of calves.They are beneficial to development of young cows,and can improve the immunity and anti-stress level of lactation cows,as well as improve the milk production and milk composition,and play a beneficial role in the prevention of mastitis and hoof disease.This paper reviewed organic trace elements effection in different physiological stages.A lot of theory were provided to dairy production.
