"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 gas does a cow produce in its lifetime?
Not sure, but . . .I can tell you with a high degree of certainty how much a cow produces in a year. Although the amounts vary from cow to cow depending upon many variables, including the quality of the feed given to the animals, a dairy cow cranks out about 142 kilograms of methane per year. (The U.S. EPA says it's more like 100 kg/yr.) Beef cattle don't fart as prolifically, squeezing out only about a little more than half as much methane, 76 kg/yr.Note that those figures DO NOT take into consideration the amount of methane produced by the decomposition of manure.----------Just to be clear, cattle and other ruminants release methane primarily by belching. It is a common misconception that cows are monstrously flatulent.
Are farts flammable?
They can be, depending on your species and what you eat. People have been injured by attempting to light them.
