酵母培养物调控瘤胃功能的研究进展

Research Progress on Regulation of Rumen Function by Yeast Culture

酵母培养物是一种独特的微生态制品,在特定工艺条件控制下由酵母在特定的培养基上经过充分的发酵后形成。酵母培养物富含蛋白质、小肽、低聚糖、维生素、矿物质、酶和许多未知生长因子,对反刍动物生长性能、免疫功能和瘤胃发酵有着显著的改善作用。本文综述了酵母培养物对反刍动物瘤胃发酵和瘤胃微生物的影响和作用机制,以期为酵母培养物调控反刍动物瘤胃功能的研究提供理论依据,为酵母培养物在反刍动物生产中的应用提供参考。

Yeast culture is a kind of unique microecological product,which is formed by yeast after full fermentation on a specific medium under the control of specific technological conditions.Yeast culture is rich in protein,small peptides,oligosaccharides,vitamins,minerals,enzymes and many unknown growth factors,and has significant positive effects on ruminant growth performance,immune function and rumen fermentation.In this paper,the effects and action mechanisms of yeast culture on rumen fermentation and rumen microorganisms in ruminants were reviewed in order to provide theoretical basis for further research on the effects of yeast culture on rumen fermentation in ruminants.
