家禽肠道黏膜形态结构及其调控的研究进展

摘要

The gut is the primary place for animals to digest and absorb nutrients, and also is the first defense barrier to resist external pathogenic microorganisms. Therefore, it is of great significance to maintain the integrity of intestinal mucosal morphology and functions for poultry health and production. Currently, researches on the functions of the intestinal mucosal barrier have become a hot topic. It was found that some nutrients and additives had positive effects on poultry intestinal mucosal morphology. In this paper, a simple review was made from the recent studies about poultry intestinal mucosal morphology and its regulation.%肠道是机体营养物质消化吸收的主要场所,也是机体抵御外界病原微生物的第一道防线.因此,良好的肠道黏膜形态结构及其功能的完整性对保持家禽健康及维持正常生产性能具有重要意义.目前,肠道黏膜的屏障保护功能研究已成热点,研究发现,许多营养素及添加剂对家禽肠道黏膜形态结构和功能都具有积极作用.本文就家禽肠道黏膜形态结构及近年来对其调控的研究进展作以简单综述.
