反刍动物胃肠道是甲烷的重要来源之一。降低胃肠道甲烷排放量，对减缓气候变暖和提高饲料利用率有着重要的意义。反刍动物胃肠道甲烷主要来自于瘤胃微生物的发酵。本文综述了瘤胃中的产甲烷菌种类、甲烷合成过程和降低胃肠道甲烷排放的营养调控新技术，期望为进一步制定甲烷减排措施提供参考。

One of the most important sources of methane is from ruminants gut. Reducing gut methane emission is significant to mitigate climate warming and improve feed utilization. Ruminants gut methane is mainly from microbe’ s fermentation in the rumen. This paper reviewed types of rumen methanogens, synthesis processes of methane and new nutritional regulation technologies for reducing gut methane emission, looking forward to pro-vide references for further studies on development of methane emission reduction measures.
