摘　　要：肠道是营养物质消化吸收的场所,食物中大分子有机物在各种酶的作用下被分解为小分子,并通过肠上皮细胞进入机体内环境,维持各组织、器官和系统的生理功能。肠道也是重要的免疫器官,机体70%左右的免疫细胞位于消化道。食物中的营养素能直接或间接作用于消化道内的免疫细胞,调节机体的肠黏膜免疫功能。因此,通过优化或调整饮食结构,靶向调节消化道免疫功能,有望成为改善猫整体免疫和健康的重要途径。本文综述了蛋白质、小肽、氨基酸、脂肪等营养素对猫消化道黏膜免疫系统的影响及调节作用,为宠物食品的合理配制进而保障宠物健康提供科学依据。The intestinal tract is a place for nutrient digestion and absorption,where large organic molecules in food are broken down into small molecules under the action of various enzymes and enter the body's internal environment through the intestinal epithelial cells to maintain the physiological functions of various tissues,organs,and systems.The intestine is also an important immune organ,and about 70%of the body's immune cells are in the digestive tract.Nutrients in food can directly or indirectly act on the immune cells in the digestive tract to regulate the body's intestinal mucosal immune function.Therefore,targeting the immune function of the GI tract by optimizing or adjusting the dietary structure is expected to be an important way to improve the overall immunity and health of cats.This paper reviewed the effects and regulation of nutrients such as proteins,small peptides,amino acids,and fats on the immune system of the digestive tract mucosa of cats,aimed to provide a scientific basis for the rational formulation of pet food and thus the protection of pet health.
