摘　　要：在高铜（２５０ｍｇ／ｋｇ）日粮中加铁、锌，可显著（Ｐ＜０．０５）或极显著（Ｐ＜０．０１）地增加血红蛋白（Ｈｂ）浓度，血清铁、锌含量和血清碱性磷酸酶（ＳＡＰ）活性，增强红细胞膜（ＲＢＣＭ）稳定性，减少血清铜含量。当日粮中加铁６０ｍｇ／ｋｇ（日粮铁总浓度１５３ｍｇ／ｋｇ）、锌１０５ｍｇ／ｋｇ（日粮锌总浓度１４２ｍｇ／ｋｇ）时，猪血清铁和锌含量、血液Ｈｂ浓度、ＳＡＰ活性、ＲＢＣＭ稳定性达到最大。在高铜日粮中加铁４０～６０ｍｇ／ｋｇ（日粮铁总浓度１３３～１５３ｍｇ／ｋｇ）、加锌７０～１０５ｍｇ／ｋｇ（日粮锌总浓度１０７～１４２ｍｇ／ｋｇ），能增加猪平均日增重７５．１５％～７６．０７％（Ｐ＜０．０１），提高饲料转化率６０．１１％～６０．７７％（Ｐ＜０．０１）。结果表明，猪高铜（２５０ｍｇ／ｋｇ）日粮中铁、锌的适宜水平分别为１５３ｍｇ／ｋｇ和１４２ｍｇ／ｋｇ。Following the supplementation of iron and zinc in diet containing 250 mg/kg of copper the iron, zinc contents, alkaline phosphatase activity in serum, hemoglobin concentration in blood and the stability of Red Blood Cell membrane increased significantly (P<0 05 or P<0 01), whereas the serum copper contents decreased in pigs. When 60 mg/kg of iron (total amount of iron in diet was 153 mg/kg) and 105 mg/kg of zinc (total amount of zinc in diet was 142 mg/kg) supplemented, except copper contents in serum, the other blood parameters were at the highest level, and the average daily gain and feed conversion efficiency increased by 75.15% 76.07% (P<0 01) and 60.11% 60.77% (P<0 01) respectively. The results showed that the optimum concentration of zinc and iron in diet containing 250 mg/kg of copper for pig should be 142 mg/kg and 153 mg/kg respectively.
