摘要
肠道既是动物机体消化吸收营养物质的主要器官,也是体内最大的免疫器官,同时还发挥着重要的屏障功能,因此肠道健康是动物健康的必要条件。锌是动物必需的微量元素之一,对动物生长发育、抗氧化和免疫等生理功能具有重要调控作用。长期以来,饲料中补充营养性锌源以无机硫酸锌为主,近年来蛋氨酸锌、乳酸锌和甘氨酸锌等有机锌源的使用越来越普遍。关于有机锌对动物肠道健康的调控作用已成为锌营养领域研究热点之一。本文从有机锌对肠道黏膜屏障、肠道免疫和肠道生物屏障的影响等方面综述了有机锌对动物肠道健康的调控作用,为有效利用有机锌改善动物健康提供重要的科学依据和理论支撑。
Intestine is the major organ of digesting and absorbing nutrients and plays an important role in protecting body against from bacterial infection.Intestinal health is the guarantee for the healthy growth of animal.Zinc,as an essential trace element,is important in growth,development,antioxidation and immunity.For a long time,inorganic zinc sulfate has been the main nutritional zinc source in feed.In recent years,the use of organic zinc such as zinc methionine,zinc lactate and zinc glycine has become more common.Now the regulatory function of organic zinc on intestine health is a hot topic.Understanding the mechanisms of organic zinc in improving intestinal health has important implications for effective using them.Therefore,the aim of the present review is to summarize the regulation of organic zinc on animal intestinal health based on mechanical barrier,immune barrier and bio-barrier.
