The microbiota that resides in the digestive tract plays pivotal role in maintaining intestinal environmental stability by promoting nutrition digestion and intestinal mucosal immunity. However, whether the intestinal microbiota in laying hens affects egg laying- performance is not known. In this study, 16S rDNA gene sequencing and fecal microbiota transplantation were used to determine the structure of the intestinal microbiota and the effect of the intestinal microbiota on egg production. The results revealed that Firmicutes were dominant in both the H (high egg laying rates) and L (low egg laying rates) groups, while Bacteroides, Actinobacteria and Proteobacteria were significantly enriched in the L group compared to the H group. The laying rates were weakly affected in H hens transplanted with the fecal microbiota from L hens, except for temporary fluctuation, while the egg laying rates were significantly increased in L hens transplanted with the fecal microbiota from H hens. Therefore, we concluded that the population structure of the intestinal microbiota varied between the H and L groups, and the intestinal microbiota of high-yield laying hens had significant effects on low-yield laying hens performance.
栖息在消化道内的微生物群通过促进营养消化和肠道黏膜免疫，在维持肠道环境稳定方面发挥着关键作用。然而，母鸡肠道内的微生物群是否会影响产蛋性能尚不清楚。在这项研究中，我们使用 16S rDNA 基因测序和粪便微生物群移植来确定肠道微生物群的结构以及肠道微生物群对产蛋的影响。结果表明，厚壁菌门在高（产蛋率高）和低（产蛋率低）组中均占优势，而拟杆菌门、放线菌门和变形菌门在低产蛋率组中明显多于高产蛋率组。从低产蛋率母鸡移植到高产蛋率母鸡的粪便微生物群对高产蛋率母鸡的产蛋率影响较弱，除了暂时波动外，而从高产蛋率母鸡移植到低产蛋率母鸡的粪便微生物群则显著提高了低产蛋率母鸡的产蛋率。因此，我们得出结论，高产蛋率母鸡和低产蛋率母鸡的肠道微生物群种群结构存在差异，高产蛋率母鸡的肠道微生物群对低产蛋率母鸡的产蛋性能有显著影响。
