【摘要】：幼龄反刍动物是成年牛羊的后备力量,其培育的优劣直接影响到成年后的生产性能,并与畜产品品质及安全息息相关。本文从幼龄反刍动物的机体生长、物质消化代谢、瘤胃的发育及微生物区系的建立及表观遗传学在幼畜早期培育的探索等方面进行综述,系统介绍犊牛、羔羊的生长发育规律、生理营养特点以及早期培育与基因表达的关系,为幼畜健康培育提供理论支持。
[Abstract]:Young ruminant is the reserve force of adult cattle and sheep. Its cultivation directly affects the production performance of adults and is closely related to the quality and safety of livestock products. In this paper, the growth, digestibility and metabolism of young ruminants, the development of rumen, the establishment of microflora and the exploration of epigenetics in the early breeding of young animals were reviewed, and the rules of growth and development of calves and lambs were systematically introduced. The characteristics of physiological nutrition and the relationship between early cultivation and gene expression provide theoretical support for the healthy breeding of young animals.
