本试验旨在研究饲粮添加蒙脱石( MMT)和枯草芽孢杆菌( BS)对产蛋鸡盲肠菌群和肠道通透性的影响.采用2×2双因子随机设计,选择360只29周龄健康的罗曼粉壳蛋鸡,随机分为4组(每组6个重复,每个重复15只) ,分别饲喂基础饲粮(对照组) 、基础饲粮+0. 5 g/kg MMT( MMT 组) 、基础饲粮+5×108 CFU/kg BS ( BS 组) 、基础饲粮+0. 5 g/kg MMT+5× 108 CFU/kg BS( MMT+BS组) .预试期7 d,正试期70 d.结果表明:1) BS组测序获得的有效序列显著多于其他各组( P＜0.05) ,试验组测序获得的优质序列较对照组均有一定增加( P＞0.05) . 2)在门水平上,与对照组相比,MMT组梭杆菌门相对含量有降低的趋势( P＝0.072) , MM...

This study was conducted to evaluate the effects of dietary montmorillonite ( MMT) and Bacillus subtilis ( BS) on cecal microflora and intestinal permeability of laying hens. The trial used a 2×2 factorial ran﹣dom design. A total of 360 healthy 29﹣week﹣old Lohmann pink hens were randomly arranged into 4 groups with 6 replicates per group and 15 hens in each replicate. The hens in 4 groups were fed a basal diet ( control group) , the basal diet+0.5 g/kg MMT ( MMT group) , the basal diet+5×108 CFU/kg BS ( BS group) , and the basal diet+0.5 g...
