Weaning is very stressful for piglets and leads to alterations in the intestinal barrier, a reduction in nutrient absorption and a higher susceptibility to intestinal diseases with heavy economic losses. This review describes the structures involved in the intestinal barrier: the epithelial barrier, immune barrier and the enteric nervous system. Here, new insights into the interactions between feed components and the physiology and morphology of the epithelial barrier are highlighted. Dietary strategies focused on improving gut health are also described including amino acids, phytochemicals and organic acids.
断奶对仔猪来说压力很大，会导致肠道屏障改变、营养吸收减少，以及对肠道疾病的易感性增加，造成巨大经济损失。本综述描述了肠道屏障所涉及的结构：上皮屏障、免疫屏障和肠神经系统。本文重点介绍了饲料成分与上皮屏障的生理学和形态学之间相互作用的新见解。还介绍了专注于改善肠道健康的日粮策略，包括氨基酸、植物化学物质和有机酸。
