Why would you doubt it?

Kangaroos produce no methane. Your average cow produces 200 to 300 litres of methane EVERY DAY.

"As a greenhouse gas [methane is] effectively 20-21 times as strong as CO2. There is a lot less of it of course. But, from Australia's emission perspective, the big source of methane is belching sheep and cattle. And it's something like two-thirds of all the methane produced in Australia comes out of burping livestock. So it's a big deal."

Here is the source. Scientists banging on about how to get cows to stop burping methane:

Lots of degrees but as usual missing the point - there wouldn't be billions of burping cows and sheep if we weren't farming them to eat.
