Research Progress on Effects and Mechanisms of Iron on Intestinal Barrier in Livestock and Poultry
The intestinal barrier integrity is essential for the health and performance of animals.Iron,as an es-sential trace element,not only plays a key role in maintaining normal physiological functions,but also is close-ly related to the integrity of the intestinal barrier.Moderate iron intake has a protective effect on the intestinal barrier,while both deficiency and excess of iron may adversely affect the integrity and function of the intestinal barrier.In this paper,the biological functions of iron,its effects on intestinal barrier and the possible mecha-nisms involved were reviewed,so as to provide theoretical reference for rational use of iron preparations in pro-duction.[Chinese Journal of Animal Nutrition,2024,36(9):5535-5544]
