"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.

Asked in Hydrocarbons
How does a cow produce methane for belching?
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.

How methane is separated from cow dung?
Methane is separated from cow dung by subjecting the cow dung to
a heat source. From there, methane can be used as an energy source
for generating electricity on a farm.

Asked in Cows and Cattle, Dairy Management and Production, Cattle Reproduction
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.

How much cubic meters of waste does a cow produce daily?

Asked in Cows and Cattle, Pollution
Are cow farts worse than humans for the environment?
Cattle and other ruminants produce much more methane in their
intestinal gases than humans as the intestinal bacteria digest
cellulose. (Most of the gas comes out of the cow's mouth!) Methane
is a greenhouse gas and bad for the environment.
