摘要
温室效应引起的全球变暖,冰川融化,海平面上升,是全世界面临的问题。在畜牧业中,反刍动物的甲烷排放量最大,甲烷属第二大温室气体。文章综述了甲烷排放的机理,测定甲烷排放的方法、甲烷排放对瘤胃pH、NH3-N浓度和瘤胃微生物结构的影响,旨在阐明日粮结构与瘤胃发酵机制的关系,为甲烷减排和改善瘤胃发酵提供理论依据。
The issues of global warming caused by the greenhouse effect,the melting of glaciers,and rising sea levels are what the whole world is facing.In livestock husbandry,ruminants have the largest methane emissions and methane is the second largest greenhouse gas.This paper reviews the mechanism of methane emission,the method of determining methane emission and the effects of different concentrate ration of methane emission on ruminal pH,NH 3-N concentration and rumen microorganism structure,in order to clarify the relationship between diet structure and rumen fermentation mechanism and to provide a theoretical basis for methane emission reduction and improvement of rumen fermentation.
