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。

摘  要:
Young ruminants are the reserve forces for the cattle and sheep. Early rearing of young ruminants directly influence subsequent production performance of adults and quality of livestock products. Three aspects were summarized in this paper, which are growth rate, digestion, rumen development, microbiota and epigenetics. Growth rules, physiology characteristics and relationship between early rearing and gene expression in young ruminants were systematically introduced. It will provide theoretical basis for the establishment of a scientific early rearing system.
