摘　　要：选用1日龄健康艾维茵肉仔鸡,从7日龄开始,分别进行饲喂基础日粮(对照组)和基础日粮添加大豆凝集素处理,以研究不同大豆凝集素添加水平对肉仔鸡生长性能、小肠发育的影响。结果表明:日粮中添加不同水平的大豆凝集素显著降低了肉仔鸡的平均日采食量(P<0.05);0.05%和0.10%大豆凝集素添加组肉仔鸡的平均日增重、绝对增重和相对增重无显著影响(P>0.05);肉仔鸡小肠长度和重量随着日粮中大豆凝集素添加水平的升高而呈线性增加,日粮中添加0.10%大豆凝集素显著增加了肉仔鸡的小肠长度及重量。研究结果提示,日粮中添加不同水平大豆凝集素,影响了肉仔鸡生长性能和小肠发育,对动物产生了抗营养作用。Fifty-four healthy Avinin broilers at 1 days of old were randomly allocated to three treatments,each treatment containing three replicates with six broilers per replicate. All of broilers were fed the basal diet containing no soybean or soybean products at days of old from 1-6. From the 7th day,the broilers of the control were fed basal diets and the others were fed the basal diet containing 0.05% or 0.10% purified soybean agglutinin respectively to investigate the negative effects of different doses of soybean agglutinin on broiler growth performance and small intestine development. The average daily intake of broiler was significantly influenced by soybean agglutinin added in basal diet（P 〈 0. 05 ）. The average daily weight gain, absolute weight gain and relative weight gain of 0. 05% and 0. 10% treatments were not significantly influenced （ P 〉0. 05 ）. The length and weight of broiler small intestine linearly increased with the increasing doses of soybean agglutinin. The length and weight of broiler small intestine were significantly influenced when the dose of diets was 0.10%. These results indicated that the different doses of soybean agglutinin supplemented in diet influenced the broiler growth performance and small intestine development and caused detrimental effects on broiler.
