摘要
甲烷是仅次于CO2的全球第二大温室气体,其中,反刍动物年产CH4约7.7×107 t,占大气中的CH4总量的25%,而且每年还以1%的速度递增。因此研究反刍动物瘤胃甲烷的营养调控对甲烷的生成影响有重要意义。本文综述了瘤胃甲烷的产生机制、瘤胃产甲烷菌与瘤胃微生物的关系和反刍动物瘤胃甲烷的营养调控措施。
Methane is the second largest greenhouse gas in the world,whose percent is only less than that of CO2.Among them,the production of methane from ruminant animal is about 7.7×107 t every year,which takes up 25% of CH4 in the atmosphere and still increase by 1% annually.So,it has important significance to study on the influence on the formation of methane from nutritional regulation of rumen methane production in ruminant animals.This article reviews the mechanism of rumen methane production,the relationship of ruminal methanogens with rumen microorganisms and the nutritional regulation of rumen methane production in ruminant animal.
