摘　　要：本文研究了日粮中添加不同水平的豆粕提取物对肉仔鸡免疫机能和抗氧化能力的影响,为其在生产中的应用提供科学依据。150只1日龄艾维茵肉仔鸡随机分为5组,每组设3个重复,每个重复10只,对照组饲喂基础日粮,I-IV处理组在基础日粮中分别添加250 mg/kg、500 mg/kg、750 mg/kg、1000 mg/kg的豆粕提取物。试验期49 d。试验结果表明:豆粕提取物可显著提高肉仔鸡的胸腺指数和法氏囊指数(P<0.05),显著提高肉仔鸡的血清免疫球蛋白Ig A、Ig G和Ig M水平(P<0.05),显著提高肉仔鸡血清中的SOD和CAT含量(P<0.05)并降低MDA含量(P<0.05)。结论:豆粕提取物可显著提高肉仔鸡免疫机能和抗氧化能力,尤其是750mg/kg添加水平作用效果最明显。The experiment was conducted to study the effect of different adding levels of soybean meal extracts （SME） on the immune function and antioxidant capacity in broilers＇ diet in order to provide a scientific basis for its application in production. 150 1-day-old Avian broilers were randomly assigned to 5 groups, with three replicates per group. The control group was fed with basal diet and trial groups was added to soybean meal extract at four concentrations of 250 mg/kg, 500 mg/kg, 750 mg/kg and 1000 mg/kg, respectively. The experiment lasted for 49 days. Results showed that SME increased thymus index and bursa of Fabricius index significantly （P〈0.05）. SME obvious- ly improved broilers＇ serum immunoglobulin IgA, IgG and IgM level （P〈0.05）. SME increased SOD and CAT con- tent and decrease MDA content in serum remarkably （P〈0.05）. In a word, SME increased the immune function and antioxidant capacity of broilers, especially 750 mg/kg supplementation of SME had the most obvious effect.
