摘要
微生物群移植(MT)是重塑动物肠道微生物群的有效方法,将健康成年鸡的肠道或粪便微生物群移植至雏鸡,会影响受体鸡肠道微生物群的早期定殖,提高微生物多样性和丰度。宿主肠道中稳定的微生物群可防止病原菌定殖,改善饲粮消化吸收效率,从而有助于提高生长性能。本文综述了近年来国内外在鸡上开展的MT研究,分析探讨了不同研究中应用MT技术对受体鸡肠道微生物群、肠道组织形态、健康免疫和生长发育的影响,比较了在供受体鸡品种、日龄选择以及MT处理时间上的异同,以期为MT技术在鸡生产中的标准化安全应用提供参考。
Microbiota transplantation(MT)is an effective way to reshape gut microbiota of animals.Transplanting gut or fecal microbiota from healthy adult chickens to chicks could influence early colonization of the recipient chicken’s gut microbiota,and increase microbial diversity and abundance.A stable microbiota in the host gut prevents pathogenic colonization,improves the efficiency of diet digestion and absorption,thus helps improve the growth performance.This article reviews domestic and foreign MT researches conducted on chickens in recent years,analyzes and explores effects of MT technology on gut microbiota,intestinal tissue morphology,healthy immunity,and growth of recipient chickens in different studies,compares similarities and differences in selection of recipient chicken breeds,age,and MT processing time,in order to provide reference for standardization and secure application of MT technology in chicken production.
