摘　　要：为探讨壳聚糖铜(CS-Cu)对断奶仔猪生长性能、血清生化指标和血清激素的影响,选择120头体重(7.8±0.2)kg的"杜×长×大"三元杂交断奶仔猪随机分为4组,对照组饲喂基础日粮,各试验组分别在基础日粮基础上添加50、100 mg/kg CS-Cu和200 mg/kg硫酸铜,预饲期7 d,试验期30 d。结果表明:与对照组相比,50、100 mg/kg CS-Cu组和200 mg/kg硫酸铜组仔猪日增重显著提高(P<0.05),料重比显著降低(P<0.05),但是100 mg/kg CS-Cu组和200 mg/kg硫酸铜组差异不显著(P>0.05)。与对照组相比,100 mg/kg CS-Cu组血清铜蓝蛋白含量、总铁结合力、碱性磷酸酶活性、胰岛素水平显著提高(P<0.05)。结果提示,日粮中添加100 mg/kg CS-Cu与200 mg/kg硫酸铜对提高断奶仔猪日增重和降低料重比具有等同的效果。The study was conducted to observe the effects of chitosan- copper（CS-Cu）on growth performance,serum biochemical and hormone indices of weaning piglets.One hundred and twenty DurocxLandraeexYorkshire piglets with（7.8±0.2）kg body weight were randomly divided into 4 treatment groups and fed with basic diet or basic diet supplemented with 50 mg/kg CS-Cu, 100 mg/kg CS-Cu and 200 mg/kg CuSO4 respectively.Feeding trial lasted 30 days.The results showed as follows：compared with the control group, the average daily gain （ADG）of two CS-Cu groups and 200 mg/kg CuSO4 group significantly increased （P 〈 0.05）and the feed gain ratio （F/G）significantly decreased （P 〈 0.05）,but there was no significant difference between the 100 mg/kg CS-Cu group and 200 mg/kg CuSO4 group.100 mg/kg CS-Cu group significantly increased（P 〈 0.05）the ceruloplasmin content,total iron binding capacity, alkaline phosphatase activity and insulin activity.The results indicated that efficiency of 100 mg/kg CS-Cu group was similar as 200 mg/kg CuSO4 group.
