Abstract: The gut and reproductive tracts of hens are colonized by vast and complex microbial communities.The dynamic processes of this microbiome development are closely associated with different developmental stages of the host,which play significant roles in the host’s immune function,nutrient absorption,endocrine regulation,reproduction and hatching processes,as well as egg quality.The balance of gut and reproductive tract microorganisms is crucial for the health and reproductive performance of hens,and chicks may be influenced by the gut and reproductive tract microorganisms transmitted by hens during hatching.However,the current research on the mechanism of the impact of gut and reproductive tract microorganisms on reproduction and hatching in hens is not yet in-depth and systematic.The author mainly introduces the dominant microorganisms in the gut and reproductive tracts of hens at different stages,as well as the colonization patterns of microorganisms in different segments of the gut and reproductive tracts.At the same time,the relationship between gut and reproductive tract microorganisms,and the impact of gut and reproductive tract microorganisms on egg quality are also discussed.And the impact of microorganisms on the reproductive and hatching process,the pathways of microbial transmission between parents and offspring,the microbial community structure at different developmental stages of chicken embryos,and the relevant factors affecting the hatching process are explained.The aim of this article is to identify the core microbial communities of hens that regulate the reproductive process and affect hatching rate as a unique identifier for selecting high hatching rate breeders,to gain a deeper understanding of the functional structure of gut and reproductive tract microorganisms in poultry and provide insights into improving poultry production and reproductive efficiency.

Key words: gut microorganisms; reproductive tract microorganisms; hatching rate; chickens
