仔猪肠道生理特点特殊，肠道微生态环境极其复杂，研究仔猪肠道微生态环境对指导生产极其重要。本文从仔猪肠道微生态环境的生态学理论及肠道微生物区系的组成及变化、调控因素、研究方法及技术等研究进展进行综述。

As the special physiological characteristics and extremely complex micro-ecosystem of the intestine in piglets, to study the intestinal micro-ecosystem of piglets has become very important for production guidance. In this paper, advances in research on the ecology theory of intestinal micro-ecosystem in piglets, the composition and changes, the regulation factors, as well as the research methods and techniques of gut microbial flora are reviewed.［Chinese Journal of Animal Nutrition, 2010，22（5）:1181-1185］
