中文摘要：

鸡肠道中生存着丰富的微生物,这些微生物在宿主的营养代谢与免疫方面有重要作用。高通量测序技术的发展为肠道微生物的研究提供了新的思路,文章简要介绍了宏基因组学,阐述肠道微生物结构变化对宿主的影响及不同饲养条件、宿主生理特征改变对肠道微生的影响,并重点从宏基因组的层面透析鸡肠道微生物菌落结构、营养代谢特征、免疫功能与鸡的健康生长之间的关联性,以期为鸡肠道微生物的研究提供思路。

英文摘要：

There are abundant microorganisms in the gastrointestinal tract of chicken,which play important roles in the metabolism and immunity of the host.The development of high-throughput sequencing technology for intestinal microbial research provides a new way of thinking.The article elaborates that metagenomics and effects of changes in intestinal microbial structure on the host and different feeding conditions,host physiological characteristics effect on intestinal microbial.This article focuses on the analysis of correlation between the intestinal microbial colony structure and characteristics of nutrient metabolism,immune function,and healthy growth of chicken on the level of metagenomics,and we hope to provide ideas for the study of intestinal microbial.
