摘要
反刍动物的甲烷排放量约占全球人为甲烷排放量的 22%,其温室效应潜能值达二氧化碳的28 倍,已成为应对全球气候变化的核心议题.近年来,基因组学、微生物组学及饲料添加剂等领域的突破性进展,为开发多路径减排方案提供了科学依据.本文系统梳理了反刍动物甲烷生成机理、微生物群落调控机制、基因编辑技术、日粮营养优化及新型饲料添加剂研发等领域的研究进展.深化反刍动物甲烷减排技术研究,为应对全球气候变暖、提升畜牧业可持续发展水平、实现生态环境保护与畜牧产业协同发展提供参考.
Abstract
Ruminant methane emissions constitute 22%of the global anthropogenic methane sources,with a global warming potential 28 times that of carbon dioxide.This positions methane mitigation as a critical challenge in addressing climate change.Recent advancements in genomics,microbial ecology,and feed additive development have enabled multiple strategies for emission reduction.This review examines methane production mechanisms in ruminants,microbial community modulation,genetic engineering applications,dietary interventions,and feed additive innovations.Developing effective methane mitigation technologies holds significant importance for climate change mitigation,enhancing livestock production sustainability,and fostering synergy between agricultural development and environmental protection.
