本试验旨在研究蒙脱石 (MMT) 、枯草芽孢杆菌 (BS) 及其互作对蛋鸡血浆激素含量、卵巢繁殖相关基因表达和肠道微生物的影响.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+5×108CFU/kg BS (BS组) 、基础饲粮+0.5 g/kg M M T+5×108CFU/kg BS (M M T+BS组) .预试期7 d, 正试期70 d.结果表明:1) 与对照组相比, 添加MMT显著降低了蛋鸡血浆皮质醇和促肾上腺皮质激素含量 (P

This study was conducted to evaluate the effects of montmorillonite (MMT) ,Bacillus subtilis (BS) and their interaction on hormone contents in plasma,reproduction related genes expression in the ovarian and intestinal microflora of laying hens. The trial used a 2×2 factorial random design. A total of 360 healthy 29-week-old Lohmann hens were randomly arranged into 4 groups with 6 replicates per group and 15 hens in each replicate,and the hens in those 4 groups were fed a basal diet (group control) ,the basal diet+0.5 g /kg MMT (MMT group) ,the...
