Abstract: Emerging research focuses on ruminant methanogens due to their emission of methane globally. Methane emission with annual global contribution of 14.5 per cent. Livestock is one of the most important sources of greenhouse gases from agriculture, contributing more than 25% of global greenhouse gases emission. The trend and legal obligation of mitigating greenhouse gas emissions will likely to directly influence improved efficiency of livestock systems, including animal nutrition, productivity, handling and mangement. The development of mitigation strategies and the viability of their practical applications have been researched around the world. In the current review, Microbiology and biotechnological strategies such as emphasizing on animal breeding, genetic merit, unproductive animals, vaccination, immunisation and biological control, chemical defaunation that can be leads to decreasing methane production from ruminant and thereby improving animal production are discussed.
