Abstract: Flavonoids are a class of active ingredients derived from natural plants, which has excellent pharmacological effects such as antiox idant, anti-inflammatory, reducing oxidative stress, improving the structure of intestinal flora, protecting intestinal mucosa, regulating immunity and promoting growth. This paper provides a systematic review of the role of flavonoids in animal intestinal health and barrier protection, briefly describes their unique physicochemical properties, summarises their digestive, absorptive and metabolic pathways in living organisms, focuses on the interactions between flavonoids and gut microorganisms, and provides insight into how flavonoids can influence the physiological function of the intestinal barrier by mediating the intestinal microbiota and generating key metabolites, such as short-chain fatty acids, bile acids and their receptors and tryptophan and other key metabolites to influence the physiological function of the intestinal barrier. The aim is to lay a solid theoretical foundation for the development and utilization of plant-derived flavonoids in animal feeding and production practices, especially in the study of intestinal health in young animals.

Key words: flavonoids, intestinal barrier, gut microflora, short-chain fatty acids, bile acids, tryptophan
