Methane, carbon dioxide, nitrous oxide, same kind of gas any animal lets out if they got flatulence or have to burp.
A cow releases between 70 and 120 kilograms of methane a year.

Yes they do, but they burp much more than they pass gas. As a matter of fact, a cow will eructate (burp) once every minute of every day because of the proximity of the rumen to the mouth. Thus more methane is passed through the mouth than the anus, because it has a much shorter distance to travel outwards. Where the methane only has to go from the rumen to the esophagus and out the mouth, the methane gas would have to go through the abomasum, small intestine, then large intestine (which are quite long when stretched out) then finally the rectum.
Yes. Contrary to popular belief the fart gas form a cow does not contain an abnormal ammount of methane comepared to other mammals. However the gas produced when they burp does contain mehtane. Its interesting to think that if evolution allowed or some sort of ignition system tragons could be created.
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.
