Abstract

CH 4 produced by ruminants aggravates the greenhouse effect and cause wastage of feed energy, and CH 4 emissions are related to methanogens. According to the current literature, there is a symbiotic relationship between methanogens and cellulolytic bacteria, so reducing methane will inevitably affect the degradation of fiber materials.
