影响羔羊肠道发育因素研究进展

Research Progress on Factors Affecting Intestinal Development of Lambs

羔羊时期肠道发育直接影响成年后的生产性能。羔羊肠道发育受多种因素影响,如母体营养水平,饲粮能量、蛋白质和纤维物质,以及肠道微生物等,其中饲粮能量和蛋白质是主要的影响因素,早期能量和蛋白质缺乏会抑制肠道组织生长。本文综述了羔羊肠道的结构和功能,以及影响羔羊肠道发育的主要因素,为羔羊的早期科学饲养提供参考,并对羔羊肠道的研究方向提出展望。

Intestinal development during the lamb period directly affects the performance of adulthood.The development of lambs’ intestines is affected by a variety of factors,such as maternal nutrient level,feed energy,protein and fiber substances,and intestinal microorganisms,the feed energy and protein are the main influencing factors,and early energy and protein deficiency will inhibit the growth of intestinal tissue.This paper reviewed the structure and function of lambs’ intestines,and the main factors affecting the development of lambs’ intestines,provides a reference for the early scientific feeding methods of lambs,and puts forward prospects for the research direction of lambs’ gastrointestinal tract.[Chinese Journal of Animal Nutrition,2022,34(11):6894-6903]
