摘要
通过分析Fe，Zn，Cu，I，Se几种微量元素之间相互作用的关系，说明微量元素营养平衡的重要性。由于微量元素之间存在着强烈的拮抗作用和协同作用，微量元素之间必须保持适当的比例才能提高动物对微量元素的吸收利用率，进而提高饲料转化率、生产力和经济效益。对日粮中的微量元素含量忽略不计的添加方法会造成微量元素不足、过量和不平衡。要达到微量元素间的真正平衡必须考虑基础日粮中微量元素的含量，其不足部分由微量元素添加剂来补充。
The paper states the importance of organic nutrtion balance supplied by Fe, Zn, Cu,Mn, I and Se by analyzing their interactive relations. There are properties of resistant eftect and cooperative effect among them, so proper proportion of them in feeds must be ensured. Neglecting the trace elements content(TEC) of basic day feeds can lead to either lack of TEC or surplusof TEC or unbalance of TEC in organism of livestock and poultry. In order to gain red organism nutrition balance, the TEC of basic day feeds must be included, the deficien amount should be supplemented with trace elements additives.
