Because it's mainly due to how the feed they eat is digested. The digestive processes both from the rumen and from the cecum encourage byproduct which includes methane and carbon dioxide. Since these gases don't have anything to contribute to the health of the animal, they are expelled by belching and flatulence. And methane isn't just from cows: it also comes from humans, pigs, deer, horses, sheep, wolves, lions, etc. It also comes from deep in the earth and is expelled into the atmosphere.
Cows are ruminant animals, that is, they have four compartments in their stomach. When they eat grass, bacteria in the first compartment, the rumen, softens it. The cow can then bring it all back up into its mouth and chew it again (chewing the cud). Because the process of food breakdown is anaerobic (without air) it produces methane, a powerful greenhouse gas. This is mostly belched, but partly farted.
Agricultural scientists are experimenting with different food additives to try to lessen the amount of methane emissions.
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.
Because of their digestive processes. Fermentation in the rumen produces methane which must be released through flatulence or belching. All animals, however, also produce methane gas through flatulence or belching.
cows actually burp methane because they have 4 stomachs.
Yes - the decomposition of human waste is known to produce methane.
Methane is made from waste,such as:sewer gas,rotting food or animals.

No humans cannot breathe in methane
no
hello sonny saunders
78% 0of the air we breathe is nitrogen, same as the amount in the air.
Oxygen is the gas we breathe. It is colorless, odorless, and tasteless. It is essential to humans' survival.
Yes, but it is very dangerous to the human body, in that high enough concentrations in the air can result result in suffocation.
no it is completely different are bodies cant breathe that only pure oxygen(o2). although fish can breathe the dissolved oxygen in water
No it helps them breathe better.
As the atmosphere of Pluto is Methane, If you was suddenly exposed to it yes you would suffocate as there is no Oxygen for you to breathe. Methane by itself is not Toxic to us, but without the presence of Oxygen we cannot breathe.
when you breathe out, plants breathe in.
The main reason is that oxygen is abundant in the atmosphere but methane is not. Air is 21% oxygen but only 0.00018% methane, so there is not enough methane in air to be of any use.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
The same air that we humans breathe in.
Not for humans beings.
They breathe through their mouth and nose and have lungs, just like humans. :)
since humans talk when they breathe out and dogs do it when they breathe in this is the main reason why humans talk and they bark
Because we can't breathe in methane cause we will died.
