摘　　要：通过在低蛋白质饲粮中补充合成氨基酸,是解决当前养殖生产中蛋白质饲料资源短缺和降低饲料成本的有效途径之一。健全的肠道功能在维持机体健康和生产性能方面发挥至关重要的作用。动物肠道需要一定水平的营养物质来维持肠黏膜的生长以及发挥肠道功能,饲粮蛋白质水平对于肠道结构、消化吸收及免疫功能等具有显著影响。本文综述了低蛋白质饲粮对家禽肠道健康、肠道形态及屏障结构影响的研究进展,旨在为低蛋白质饲粮及相关技术在肠道功能研究和家禽生产上进一步推广应用提供参考。Supplementing synthetic amino acids in low-protein diets is one of the effective ways to solve the shortage of protein feed resources and reduce feed costs in current livestock production.Healthy gut function plays a crucial role in maintaining body health and performance.Animal guts require a certain level of nutrients to maintain the growth of intestinal mucosa and to exert gut function,and dietary protein levels have significant effects on intestinal structure,digestion and absorption,and immune function.We reviewed the research progress on the effects of low-protein diets on the intestinal health,intestinal morphology and barrier structure of poultry,aiming to provide a reference for the further promotion and application of low-protein diets and related technologies in intestinal function research and poultry production.
