| 摘 要： | 本试验旨在探讨青贮玉米籽实对蛋鸡生产性能、蛋品质和肠道内环境的影响.试验选用55周龄海兰褐蛋鸡200只,随机分成4组,每组5个重复,每个重复10只鸡.4组蛋鸡分别饲喂含0(对照组)、1％、2％和4％青贮玉米籽实的饲粮,试验期为7周.结果表明:与对照组相比,2％和4％青贮玉米籽实组产蛋率、平均日产蛋量、蛋壳颜色、哈夫单位均显著提高(P＜0.05),料蛋比显著降低(P＜0.05),盲肠和空肠中大肠杆菌数量显著降低(P＜0.05)、乳酸杆菌数量显著提高(P＜0.05)；1％青贮玉米籽实组平均日产蛋量、哈夫单位、空肠与盲肠中乳酸杆菌数量显著提高(P＜0.05),空肠中大肠杆菌数量显著降低(P＜0.05)；4％玉米籽实组空肠和盲肠pH显著降低(P＜0.05).以上结果提示,饲粮中添加适量青贮玉米籽实能够提高蛋鸡的生产性能和蛋品质,改善肠道内环境,综合各项指标可知,添加2％青贮玉米籽实效果最好. |

| Abstract: | This experiment was conducted to study the effects of silage corn seeds on performance,egg quality and intestinal environment in laying hens.Two hundred 55-week-old Hy-Line laying hens were randomly divided into 4 groups with 5 replicates per group and 10 hens per replicate.The laying hens in the 4 groups were fed the basal diet with 0(control group),1%,2% and 4% silage corn seeds,respectively.The experiment lasted for seven weeks.The results showed as follows: compared with the control group,laying rate,average daily egg production,eggshell color,Haugh unit and the number of Lactobacillus in jejunum and caecum of laying hens fed the diets containing 2% and 4% silage corn seeds were increased significantly(P<0.05),while feed to egg ratio and the number of Escherichia coli in jejunum and caecum were decreased significantly(P<0.05).Average daily egg production,Haugh unit,the number of Lactobacillus in jejunum and caecum of laying hens fed the diets containing 1% silage corn seeds were increased significantly(P<0.05),while the number of Escherichia coli in jejunum and caecum was decreased significantly(P<0.05).pH of jejunum and caecum of laying hens fed the diets containing 4% silage corn seeds was decreased significantly(P<0.05).It is concluded that silage corn seeds can improve performance,egg quality and intestinal environment of laying hens,and the addition of 2% silage corn seeds to the diet is ideal. |
