摘要
反刍动物胃肠道发育与微生物区系的演变都呈现一定规律,而且胃肠道发育与微生物定植的关系表现为相辅相成;然而,幼龄反刍动物胃肠道发育不完善,随着日龄增长和外界因素的刺激,逐渐由非反刍阶段向反刍阶段转变;本文概述了幼龄反刍动物胃肠道发育规律与微生物区系演变过程,从饲粮形态及营养水平、添加剂、饲养管理以及微生物移植等方面综述了幼龄反刍动物胃肠道发育及微生物区系的调控进展,旨在为深入开展幼龄反刍动物相关研究提供基础。
The evolution of gastrointestinal tract development and microbial flora of ruminants show a certain regularity,and the relationship between gastrointestinal tract development and microbial colonization is complementary.However,the gastrointestinal development of young ruminants is imperfect and requires the stimulation of external factors to complete the transformation from non-rumination stage to rumination stage.This paper summarized the development of gastrointestinal tract and the evolution of microlflora of young ruminants,explained the regulation of gastrointestinal development and microflora of young ruminants from the aspects of dietary morphology and nutritional level,additives,feeding management and microbial transplantation,aimed to provide suggestions for further study of young ruminants in the future.
