反刍动物甲烷排放现状及调控技术研究进展

Research Progress in Methane Emission from Ruminant and Control Techniques

甲烷是反刍动物消化代谢的产物。但反刍动物胃肠道发酵排放甲烷不仅造成了能量的损失,而且也是导致环境温室效应的重要因素之一。因此,如何调控反刍动物瘤胃甲烷气体的产生,从而减少其排放量,对提高饲料能量的利用效率和提高动物生产力以及改善环境具有重要意义。文章从反刍动物瘤胃甲烷气体的产生机理、影响甲烷合成的影响因子以及调控减排技术研究进展等方面做一详细综述。

Methane is the product of digestion and metabolism in ruminant. However, emissions of methane from ruminant gastrointestinal fermentation not only caused the loss of energy, but also the greenhouse effect in the environment. It is very significant how to reduce methane emission from ruminant rumen,improve animal productivity and improve the environment. This paper reviewed mainly mechanism,influenceing factors of methane emission from ruminant rumen and the measures for reducing itts emission.
