摘　　要：肉鸡肠道微生物群在维持肠道健康方面发挥着关键作用,具有维持肠道内环境稳定所必需的生理调节功能,可以通过竞争性排斥有害微生物和病原体,同时发酵养分提高宿主生产性能。肠道微生物稳态易受鸡舍环境、营养和宿主等因素的影响,并且很难确定能稳定影响肉鸡免疫和生产性能的特定种群及丰度。文章综述了影响肉鸡肠道微生物群定植过程的主要因素、与宿主免疫稳态的相互作用及其对肠道健康和生产性能的影响,以期为肠道微生物群在肉鸡健康生产中的合理应用提供理论依据。The intestinal microbiota of broilers plays a key role in maintaining intestinal health.It has the physiological regulation function necessary to maintain the stability of intestinal environment,harmful microorganisms and pathogens can be competitively excluded.At the same time,it can ferment nutrients to improve host production performance.The intestinal microbial homeostasis is easily affected by factors such as chicken house environment,nutrition and host,and it is difficult to determine the specific population and abundance that can stably affect the immunity and production performance of broilers.This paper reviewed the main factors affecting the colonization process of broiler intestinal microbiota,the interaction with host immune homeostasis,and its impact on intestinal health and production performance,in order to provide a theoretical basis for the rational application of intestinal microbiota in healthy production of broilers.
