摘　　要：羔羊易发生肠道炎症,主要是因为其胃肠道(gastrointestinal tract,GIT)微生物发育尚不成熟,缺乏抵御病原菌的共生菌群。羔羊GIT微生物群的演替与其对营养物质的吸收及免疫系统的发育密切相关,靶向重建GIT微生物群具有抵抗肠道炎症发生的潜力。早期生命阶段是GIT微生物群建立和发育的关键时期,对动物后期生长性能和免疫系统的发育具有长远影响。因此,深入了解羔羊GIT微生物群的定植规律及影响因素,可为羔羊GIT疾病的预防提供理论依据。文章对羔羊GIT微生物群的定植过程、功能及定植的影响因素进行综述,阐述了羔羊GIT微生物群与营养物质吸收及免疫系统发育之间的相互关系,为羔羊GIT微生物群的相关研究提供参考。Lambs are prone to intestinal inflammation mainly because of less developed gastrointestinal tract(GIT)microbiota and the lack of symbiotic microbiota to resist pathogens in lambs.The evolution of GIT microbiota in lambs is closely associated with its absorption of nutrients and the development of the immune system,and the targeted reconstruction of GIT microbiota has the potential to resist intestinal inflammation.The early stage of the life is critical for the establishment and development of GIT microbiota,which has a long-term impact on the growth performance and immune system development of animals in the later stage of the life.Therefore,a deeper understanding of the colonization patterns and factors influencing GIT microbiota could provide theoretical basis for the prevention of GIT diseases of lambs.This article provides a review of the colonization process,functions,and factors influencing GIT microbiota,and elucidates the interrelationships between the GIT microbiota,nutrient absorption,and immune system development in lambs,providing reference for related research on lamb GIT microbiota.
