摘要
在大约克夏×姜曲海生长肥育猪的饲粮中，添加氨基酸螯合铜、硫酸铜，饲喂结果表明，饲粮中添加氨基酸螯合铜，促进生长肥育猪增重、改善饲料转化率和经济效益均优于硫酸铜，且肥育前期优于肥育后期。肝脏中Ｃｕ，Ｚｎ，Ｆｅ的含量高于背最长肌含量。血浆中３种徽量元素含量各组差异不显著。
Feeding experiments were carried out by adding animo acid-chelated copper or CuSO_4 to thediet of Large White×Jiangquhai crossabred growing-finishing pigs. The results indicated that the group ofanimo acid-chelated copper was better than the group of CuSO_4 in average daily gain,feed conversion effi-ciency and economic result, and that it was more obvious for Cu to enhance pig growth during growing periodthan during finishing period.The level of Cu,Fe,Zn in liver was higher significantly than that in longis-simus.Plasma level of Cu,Fe,Zn did not differ greatly between groups.
