植物多酚调控幼龄反刍动物瘤胃发育的作用机制及应用研究进展OA

Ruminants,as important sources of high-quality protein,have a close relationship between their production performance and rumen development,and the young stage is a critical period for rumen function improvement.Plant polyphenols,as secondary metabolites of plants,have characteristics such as antioxi-dant,anti-inflammatory,and regulation of microbial activity.They can significantly promote rumen develop-ment in young ruminants by optimizing rumen fermentation parameters(such as adjusting volatile fatty acid ratios,stabilizing pH values,and reducing ammonia nitrogen concentrations),promoting beneficial bacterial proliferation,enhancing rumen epithelial development(such as improving nipple morphology and barrier function),and regulating digestive enzyme activity through multiple pathways.This article systemati-cally reviews the mechanism and potential applica-tions of plant polyphenols on rumen development,providing a theoretical basis for improving the pro-duction efficiency of ruminants,reducing breeding costs,and promoting sustainable development of animal husbandry.
