    家畜肠道和粪便甲烷排放研究进展

    Advance in enteric and manure-derived methane emissions from domestic animals

    • 摘要: 家畜采食饲料在胃肠道发酵及其排泄粪便在处理贮存过程中会产生甲烷,目前每年的排放量超过全球甲烷排放总量的1/4。甲烷是主要的温室气体,会破坏大气臭氧层。减少家畜肠道和粪便的甲烷产量对提高饲料能量利用率和改善环境具有重要意义。该文在对目前反刍动物甲烷排放影响因素、肠道甲烷排放量和粪便甲烷排放量测定方法等方面的研究现状进行分析的基础上,就如何减少家畜肠道和粪便的甲烷产量提出了自己的看法。

       

      Abstract: Enteric and manure-derived methane emissions from domestic animals around the world per year now are above 1/4 of total methane emissions. Methane, a principle greenhouse gas, can damage the ozonosphere. Methane emissions mitigation not only can improve utilization of feed energy, but also meliorate environment. This article reviews the influencing factors of methane emissions, methods used to measure enteric and manure-derived methane emissions from domestic animals. On the bases of these, advices on how to readuce the methane emission from enteric and manure are given.
