摘要
地方猪具有耐粗饲的优点,该优良性状在培育民族地方猪种源中发挥着不可替代的作用。肠道微生物是地方猪耐粗饲的重要载体,能够充分利用日粮纤维,具有改善猪群肠道发育,维持肠道健康,调节肠道黏膜屏障的功能。本文从地方猪肠道微生物演替规律、分布规律和影响肠道微生物的因素入手,研究肠道微生物高效利用日粮纤维组份的分子机制,并阐明日粮不同组份条件下肠道微生物动态变化情况和肠道微生物的表观遗传修饰调控模式,意旨为地方猪耐粗饲的生物学机理与开发新型微生物制剂提供技术参考。
Local pigs have the advantage of tolerance to rough feeding,which plays an irreplaceable role in breeding ethnic local pig provenances.Intestinal microbiota is an important carrier for feeding tolerance of local pigs,which can make full use of dietary fiber,play a role in improving intestinal development,improving intestinal health and regulating intestinal mucosal barrier.This paper,from the perspective of intestinal microbiota of local pigs,studied the molecular mechanism of intestinal microbiota's efficient utilization of dietary fiber components.The dynamic changes of intestinal microbiota under different dietary components were systematically elucidated,which was intended to provide technical reference for the biological mechanism of crude feeding tolerance and the development of new microbial agents in local pigs.
