"Methane emissions per animal from this assessment are comparable to figures
obtained by Schils et al. (2007b), Cederberg et al. (2009) in OECD countries (ranging from 110 to 130 kg methane per cow per year) and by Herrero et al. (2008) in Africa (ranging between 21 and 40 kg methane per livestock unit per year)."
This source has also mentioned how incomplete studies have been on the actual methane production of cattle because of the various changes in feed, feed type, individuality in cattle, as well as the emissions from manure. Methane is a natural gas in the Earth, and the amount that comes from cattle is actually more insignificant than that naturally produced from such sources as volcanoes, the oceanic floor, swamps, etc.

how much methane gas can we get from 10 Kg cow dung.

Methane if i splet it write
Cows don't produce methane - the bacteria in their rumens produce methane. This is through anaerobic fermentation of grains, grasses and legumes that the cows eat. The belch is simply the release of that gas, which the cow has no use for.
A cow releases between 70 and 120 kilograms of methane a year.

the gas produced in a cows stomach is methane.
Cows emit the majority of their methane gasses through belching. Studies vary, but it is said that one cow can produce between 100 liters and 500 liters of methane gas per day.
