Scope of dairy goat production in India Methane in the atmosphere has doubled due to human activity during the last 200 years. Methane is thought to be responsible for 23% of all greenhouse gas-induced warming, making it the second-largest contributor to global warming after carbon dioxide (CO2). CH4 emission from Indian livestock was 15.3 Tg in 2012. One of the major human-caused producers of methane (CH4) in the world is livestock farming in India. The largest source of naturally occurring methane is wetlands, and it is estimated that agriculture accounts for 27.3% of all methane emissions. One of the most significant GHGs, methane has a 28-fold greater potential to cause global warming than carbon dioxide. To diminish methane reduction various strategies can be used like the use of bacteriocins, change in dietary profile, defaunation, vaccinations against microbes or monensin as an antibacterial
