摘要
微量元素在奶牛生产中的重要作用已逐渐被人们认知,但如何正确、合理使用仍是有待研究的问题。本文对奶牛生产中常见的微量元素铜、锌、锰、钴的作用,缺乏及添加过量的危害,以及不同使用形式(有机、无机)对奶牛泌乳性能的影响进行了综述,以期为养殖生产者合理使用微量元素提供理论依据。
The important role of trace elements in dairy production has gradually been cognitive, out it 1s me issue that how to correct and rational use of them. In this paper, the role of common trace elements（including copper, zinc, salt, cobalt） in dairy production, the hazards of lacking and adding excessive, and the effects of different forms（organic or inorganic） on dairy production performance were reviewed, in order to propose theoretical basis for the reasonable use of trace elements for dairy production.
