【摘要】 新生仔猪存活率和生长状况是影响养猪生产经济效益的关键因素之一。肠道微生物的早期定植对新生仔猪的肠道发育、营养吸收以及免疫调节均具有重要作用。本文系统综述了仔猪肠道微生物早期定植规律、影响因素及其调控的研究进展,以期在理解新生仔猪肠道微生物定植规律的基础上比较不同调控方式的效果与机制,为生产实践中改善新生仔猪生长性能和存活率提供理论依据与应用措施。更多还原

【Abstract】 The survival rate and growth performance of neonatal piglets significantly affect the economic benefits of pig production. Early-life gut microbiota colonization plays an important role in intestinal development, nutrient absorption, and immune regulation of neonatal piglets. This article reviews the research progresses on the early-life gut microbiota colonization of piglets, as well as the influencing factors and its regulation. Meanwhile, based on the understanding of gut microbiota colonization succession, the mechanisms and effects of different regulating methods were compared to provide theoretical basis and application measures for improving the growth performances and survival rate of neonatal piglets in pig production.更多还原
