摘　　要：通过在饲料中添加红车轴草(Trifolium pretense L.)异黄酮,研究其对AA肉鸡免疫器官、免疫球蛋白及抗氧化性能的影响。选用180羽1日龄AA肉仔鸡分成3组,即对照组、处理Ⅰ组、处理Ⅱ组,分别饲喂基础日粮、基础日粮+红车轴草异黄酮(10 mg.kg-1)、基础日粮+红车轴草异黄酮(20 mg.kg-1)。结果表明:处理组的肉鸡日增重和免疫器官指数均高于对照组,饲喂21 d后,处理组血清IgM的含量显著高于对照组(P<0.05),49 d后,处理Ⅰ组肉鸡血清IgG含量显著高于对照组(P<0.05);红车轴草异黄酮提高了血清中谷胱甘肽过氧化物酶(GSH-PX)活性,降低了丙二醛(MDA)含量,处理Ⅰ组和处理Ⅱ组之间差异不显著。红车轴草异黄酮能够明显改善肉鸡生产性能、调节免疫和提高机体的抗氧化性。The effect of red clover isoflavone on Immune Organs,Igs and Anti-oxidation Activity of Broilers was investigated.One-day-old AA broiler Chicks were randomly assigned to three groups（control,group 1 and group 2）.Basic diet,basic diet＋red clover isoflavone（10 mg·kg-1） and basic diet＋red clover isoflavone（20 mg·kg-1） were fed to three groups respectively.Results indicated that red clover isoflavone increased daily weight and immune organ indexes.IgM contents in serum of both group 1 and 2 on 21 days after feeding were higher than control（P0.05）.IgG contents in serum of group 1 were higher than control on 49 days after feeding（P0.05）.Red clover isoflavone also enhanced GSH-PX activity and reduced MDA content in serum.Group 1 and group 2 had no significant difference.These results showed that red clover isoflavone could modulate growth performance and immunity of broiler chicks as well as increase anti-oxidation activity of broiler chicks.
