摘　　要：文章旨在研究日粮添加杜仲叶粉对断奶仔猪生长性能、血清抗氧化指标和免疫功能的影响。试验选择体重相近[(6.71±0.15)kg]、体况良好的24日龄断奶仔猪320头,随机分为4组,每组8个重复,每重复10头。对照组饲喂基础日粮,试验组分别向基础日粮中添加300、600和900 mg/kg的杜仲叶粉。试验共41 d(其中预饲期6 d,正试期35 d)。试验结果表明,随杜仲叶粉添加量的提高,断奶仔猪平均日增重和终末体重显著提高(P <0.05),料重比显著降低(P <0.05),600和900 mg/kg处理组仔猪的生长性能最佳,显著优于0和300 mg/kg组;此外,日粮添加杜仲叶粉对断奶仔猪平均日采食量无显著影响(P> 0.05)。日粮添加杜仲叶粉对断奶仔猪肝脏指数、肾脏指数、脾脏指数和腹股沟淋巴结指数均无显著影响(P> 0.05)。日粮添加600和900 mg/kg杜仲叶粉可显著提高断奶仔猪血清免疫球蛋白IgA、IgM和IgG含量(P <0.05);日粮添加600和900 mg/kg杜仲叶粉可显著提高断奶仔猪血清GPX活性(P <0.05);日粮添加杜仲叶粉可显著提高断奶仔猪血清T-SOD和Cu-Zn SOD活性(P <0.05),此外,日粮添加杜仲叶粉对断奶仔猪血清CAT活性无显著影响(P> 0.05)。总之,本试验结果表明,日粮添加杜仲叶粉可以提高断奶仔猪生长性能,改善机体血清抗氧化指标和免疫功能,在本试验条件下,断奶仔猪日粮杜仲叶粉最适添加量为600 mg/kg。The aim of this study is to investigate the effects of adding Eucommia ulmoides leaf powder to the diet on the growth performance,serum antioxidant indicators,and immune function of weaned piglets.320-24 day old weaned piglets with similar body weight[(6.71±0.15)kg]and good physical condition were selected and randomly divided into 4 groups,with 8 replicates in each group,with 10 piglets per replicate.Add 300,600,and 900 mg/kg of Eucommia ulmoides leaf extract to the basic diet as the experimental feed.The experiment lasted for a total of 41 days(including 6 days of pre test and 35 days of trial).The experimental results showed that with the increase of Eucommia ulmoides leaf powder addition,the average daily gain and final body weight of weaned piglets significantly increased,while the feed to weight ratio significantly decreased(P<0.05);The growth performance of the treatment groups with an addition of 600 and 900 mg/kg was the best,significantly superior to the 0 and 300 mg/kg groups;In addition,the addition of Eucommia ulmoides leaf powder to the diet had no significant effect on the average daily feed intake of weaned piglets(P>0.05).The addition of Eucommia ulmoides leaf powder to the diet did not significantly affect the liver index,kidney index,spleen index,and inguinal lymph node index of weaned piglets(P>0.05).The addition of 600 and 900 mg/kg Eucommia ulmoides leaf powder to the diet significantly increased the levels of serum immunoglobulin IgA,IgM,and IgG in weaned piglets(P<0.05);The addition of 600 and 900 mg/kg Eucommia ulmoides leaf powder to the diet significantly increased the serum GPX activity of weaned piglets(P<0.05);The addition of Eucommia ulmoides leaf powder to the diet significantly increased the T-SOD and Cu Zn SOD activities in the serum of weaned piglets(P<0.05).In addition,the addition of Eucommia ulmoides leaf powder to the diet had no significant effect on the serum CAT activity of weaned piglets(P>0.05).In summary,the results of this experiment indicate that the optimal amount
