摘要
微量元素不仅能够满足机体基本生理需求,还能满足动物机体繁殖、免疫、生产性能等特殊需求。微量元素不可以相互转换及替代,虽然需要量极少,但如果缺乏,机体生命活动便不能正常进行。但是目前在使用微量元素过程中,盲目超标现象十分普遍。文章针对畜禽日粮中微量元素应用存在问题,从微量元素添加量与需要量的不平衡、添加进程及高剂量微量元素的潜在危害3个方面综述畜禽日粮中微量矿物元素应用现状。
Meanwhile, trace elements do not only satisfy the basic physiological needs but also improve, reproduce the immune and production capacity. The trace elements can not be transformed and substituted by one another and with precious demand. However, the self stable state will not apply if there was lacking of trace elements. But in the process of using trace elements; the phenomenon was commonly used in high doses. This article mainly reviewed the problem of trace elements application from unbalance of requirement and addition, adding process and harmful effect of trace elements.
