反刍动物瘤胃甲烷生成中辅酶F430的功能及其营养调控机制OA

Rumen methane emissions from ruminants represent a significant source of agricultural greenhouse gas emissions and are a key target for advancing carbon reduction in livestock production.Methyl-coenzyme M reductase and its core coenzyme F430 play essential roles in methane synthesis,serving as critical sites for regulating ruminal methanogenesis.This review focuses on the mechanisms of rumen methane production,systematically summarizes the regulatory functions of MCR and F430 in methane synthesis,and analyzes the impact mechanisms of nutritional interventions—such as seaweed,3-nitrooxypropanol and nitrates—on F430 functionality.The aim is to provide insights for methane mitigation in ruminant production under the"dual carbon"goals,while identifying novel nutritional targets for controlling rumen methane emissions.
