【摘要】 维生素A是动物为维持正常生理功能而必须从饲料中获得的一类微量脂溶性维生素。维生素A对动物的生长、发育、繁殖、健康等生产性能有重要作用,而生产性能受基因表达的调控。本文综述了维生素A对动物生产性能的影响,以及其对主效基因表达的调控作用,从而更加全面地探讨维生素A对动物生产性能的调控机理。更多还原

【Abstract】 Vitamin A is of the trace fat-soluble vitamins which must be obtained from feed by animals to maintain the normal physiological function.Vitamin A plays important roles in animal’ s growth,development,reproduction and health production performance,which are regulated by gene expression.This paper reviews the effects of vitamin A on animal performance and regulation of main effect ongenesexpression,thus further explore the regulation mechanism of vitamin A to animals production performance.更多还原
