摘　　要：为了提高生长性能,减少抗菌化合物的使用,开发新的饲养管理与营养策略来刺激断奶仔猪肠道发育对养猪业的长期可持续性至关重要。营养和能量摄入不佳、微生物群不平衡、免疫功能不成熟和受损、断奶引起的应激等都可能通过损伤黏膜和紧密连接完整性而影响消化吸收效率和肠道屏障功能。因此,断奶期仔猪对可能由血清型产毒大肠杆菌引起的致病性肠病(如断奶后腹泻)高度敏感。许多饲料成分(如蛋白质、纤维、饲料添加剂和矿物质)会影响胃肠道中的微生物生长,进而影响猪的生长和健康。目前抗生素在猪生产限用和禁用,某些饲料添加剂被视为抗生素的替代品,并在猪的营养中发挥重要作用。To improve growth performance and reduce the use of antimicrobial compounds,the development of new feeding management and nutrition strategies to stimulate intestinal development and health in weaned piglets is critical to the long-term sustainability of the pig industry.Poor nutrition and energy intake,microbiome balance,immature and impaired immune function,and physical and mental stress caused by weaning may affect digestion and absorption efficiency and intestinal barrier function through mucosal damage and tight junction integrity.Therefore,weaning pigs are highly sensitive to pathogenic bowel diseases(such as post-weaning diarrhea)that may be caused by serotype toxigenic escherichia coli.Many feed ingredients,such as protein,fiber,feed additives and minerals,affect the growth of microorganisms in the gastrointestinal tract,which in turn affects the growth and health of pigs.In the context of global restrictions and prohibitions on the use of antibiotics in pig production,certain feed additives are seen as substitutes for antibiotics and play an important role in the nutrition of pigs.
