摘　　要：微量元素(主要包括铁、锌、硒、铜、锰、碘)对牦牛的生长发育极其重要,如果牦牛缺乏微量元素会导致生长缓慢、免疫功能下降,最终影响健康及生产力,严重缺乏还会导致死亡。笔者综述了微量元素对牦牛瘤胃发酵、生产性能的影响及土壤、牧草、牦牛机体中微量元素之间的关系和微量元素在牧草中含量的变化,探讨了牦牛补充微量元素的途径,以期为开发牦牛微量元素补充剂提供参考。Trace elements(including iron,zinc,selenium,copper,manganese and iodine)are extremely important for yak growth and development.Trace elements deficiency in yaks can lead to slow growth,reduced immune function,and ultimate impact on health and productivity.Severe deficiency can also lead to death.The author reviewed the effects of trace elements on rumen fermentation and production performance of yaks,the relationship between trace elements in soil,herbage and yak body,and the changes of trace elements content in herbage.The way of supplementing trace elements in yaks was discussed in order to provide reference for the development of trace elements supplement in yaks.
