探讨日粮中添加大豆低聚糖（SBOS）对爱拔益加（AA＋）肉鸡生产性能、免疫功能和肠道菌群的影响，选取1日龄健康的AA＋肉仔鸡720羽，随机分为对照组（基础日粮）、试验Ⅰ组（基础日粮＋0．1％SBOS）、试验Ⅱ组（基础日粮＋0．3％SBOS）和试验Ⅲ组（基础日粮＋0．5％SBOS），每组6个重复，每个重复30只，试验期42天。结果表明：与对照组相比，日粮中添加大豆低聚糖AA＋肉仔鸡平均日增重有一定程度的增加，但差异不显著；能显著降低22～42日龄AA＋肉鸡平均日采食量及22～42日龄和1～42日龄料重比。明显提高21、42日龄的免疫器官指数、盲肠内双歧杆菌和乳酸杆菌的数量。大豆低聚糖适宜的添加水平为0．3％。

The effects of dietary soybean oligosaccharides(SBOS)on the growth performance,immunity function and intesti-nal flora of AA+broilers were studied.Seven hundred and twenty one-day-old AA+broilers were randomly divided into controlgroup (basal diet),treatmentⅠgroup(basal diet+0.1%SBOS),treatmentⅡgroup(basal diet+0.3%SBOS)and treatment Ⅲgroup(basal diet+0.5%SBOS),each group had 6 replicates and 30 AA+broilers in each replicate.The experiment period was42 days.The results showed that:compared to the control group,the average daily gain of AA+broilers supplementation ofSBOS increased to a certain extent,but the difference was not significant;SBOS could significantly decrease average daily feedintake of 22~42 d broilers,and feed to gain ratio of 22~42 d and 1~42 d broilers;and SBOS could significantly increase im-mune organ indexes,the number of Bifidobacterium and Lactobacillus in caecum of 21-day-old and 42-day-old AA+broilers.The suitable addition level of soybean oligosaccharide was 0.3%.
