摘要 试验以AA肉鸡为研究对象,研究在日粮中应用微生态发酵蛋白饲料对肉鸡生长性能和肠道微生物菌群的影响。选择1日龄AA肉仔鸡360羽,随机分成对照组和试验I、Ⅱ组3个处理组。每组3个重复。每个重复40羽。对照组饲喂基础日粮,试验Ⅰ、Ⅱ组分别用5%和10%微生态发酵蛋白饲料替代基础日粮中的等量豆粕。结果表明:1~21日龄和1~42日龄阶段的平均日增重,试验Ⅰ、Ⅱ组比对照组分别提高5.0%,9.6%和7.0%,11.5%(P<0.05);1~21日龄和1~42日龄阶段的料重比,试验Ⅰ、Ⅱ组分别比对照组降低9.0%,10.2%和8.1%,12.1%(P<0.05);应用微生态发酵蛋白饲料可使1~21日龄和21~42日龄肉鸡,大肠杆菌数量分别降低4.37%、5.26%和13.1%、12.6%(P<0.05);提高肠道双歧杆菌和乳酸杆菌数量10.2%、9.6%、6.3%、9.2%和7.8%、9.2%、13.2%、13.7%(P<0.05)。
