摘　　要：本试验旨在研究不同替代水平辐照豆粕对肉鸡生产性能、血清生化指标及免疫器官指数的影响，以确定辐照豆粕在肉鸡日粮中的适宜添加水平。试验选取体重相近且健康状况良好的1日龄肉仔鸡560只，随机分成4组（每组4个重复，每个重复34只）：对照组饲喂基础饲粮，试验组在基础饲粮的基础上用辐照豆粕替代普通豆粕，辐照豆粕占日粮的比例分别为0％、5％、10％、15％的辐照豆粕替代普通豆粕。试验期42天。结果表明：（1）试验前期（1～21天），辐照豆粕对肉鸡生产性能无显著影响（P〉0．05），但从后期（22～42天）及整个试验期看，辐照豆粕能够显著降低肉鸡饲料增重比（P〈0．01）；（2）10％、15％辐照豆粕均能够显著提高肉鸡血清总蛋白浓度（P〈0．05）；（3）10％、15％辐照豆粕均能够显著提高肉鸡血清T—SOD活力（P〈0．01）；（4）10％辐照豆粕能够显著提高肉鸡胸腺指数（P〈0．05）。由此可见，辐照豆粕替代普通豆粕后，有助于促进肉鸡生长，提高其免疫力与抗氧化能力。To determine the optimum supplemental level of irradiation-soybean for broiler diet, this experiment was conducted to investigate the effects of irradiation-soybean on performance, serum biochemical indexes and the immune organ index in broilers. 560 healthy broilers with near weight were randomly allocated to 4 groups with 4 replicates per group and 34 chickens per replicate. Control group was fed a basal diet, and test groups were fed the basal diet replaced some of common soybean meal with 5%, 10% and 15% irradiation-soybean meal, respectively. The experiment lasted for 42 days. The results showed as follows： （1） The average daily gain and average daily feed intake of broilers among groups were not different significantly （P〉0.05） during 1-21days. The feed/gain of groups fed irradiation-soybean was significantly reduced during 1-42 day （P〈0.01）. （2） Compared with the control group, the total serum protein of broilers with diets supplied 10% and 15% irradiation-soybean increased significantly （P〈0.05）. （3） The diet with 10% and 15% irradiation-soybean can significantly improve the serum T-SOD activity （P〈0.01）. （4） The thymus index of broilers in group supplemented 10% irradiation-soybean was higher（P〈0.05）. It is concluded that the irradiation-soybean supplementation in the basal diet can promote the growth of broilers, and improve the immunity and oxidation resistance.
