瘤胃氧化还原电位研究进展

Research Progress of Redox Potential in Rumen

氧化还原电位(Eh)是瘤胃内环境的重要理化参数之一,是瘤胃细菌活性的指示剂,也是衡量瘤胃发酵动力学的基本参数。在瘤胃发酵过程中,瘤胃Eh与挥发性脂肪酸(VFA)的合成存在密切联系。本文主要针对瘤胃Eh的作用机制、影响因素、测定方法以及其对瘤胃微生物组成和纤维素降解的影响进行综述,旨在为进一步研究瘤胃发酵和瘤胃微生态系统提供参考。

Redox potential(Eh)is one of the important physicochemical parameters of rumen environment,an indicator of rumen bacterial activity,and a basic parameter to measure rumen fermentation kinetics.Rumen Eh is closely related to the synthesis of volatile fatty acid(VFA)during rumen fermentation.In this paper,the mechanism of action,influencing factors,determination methods of rumen Eh and its effects on rumen micro-biota composition and cellulose degradation were reviewed,aiming to provide references for further research on rumen fermentation and rumen microecosystem.
