粗饲料对幼龄反刍动物瘤胃发育的影响及其作用机制
Effects of Forage on Rumen Development in Young Ruminants and Its Mechanisms
摘要
Abstract
The rumen of young ruminants is non?functional with un?complete structure, and its microbiota has not yet been established. Structure and function of rumen undergo great changes in the first few months after birth. Meanwhile, functional rumen is vital to promote performance in adult life. Recent studies have shown that feeding young ruminants with only concentrate feeds reduced rumen fluid pH and caused ruminal papillae clumping and hyperkeratinization. However,supplemented feeding forage early in life can increase rumen fluid pH, stimulate the development of muscular layer of the rumen, and maintain healthiness of the rumen wall. This paper mainly reviewed effects of source, level and particle size of forage on regulating ruminal structure and morphology, microbiota, fermentation parameters and epithelium function of adsorption and transporta?tion,and the potential mechanisms were also reviewed,aiming to provide references for the application of for?age in feed of young ruminants.关键词
