Does livestock produce methane?

Ruminant livestock can produce 250 to 500 L of methane per day. This level of production results in estimates of the contribution by cattle to global warming that may occur in the next 50 to 100 yr to be a little less than 2%.

Can you stop cows producing methane?

Many plant secondary compounds such as tannins, saponins or essential oils have been shown to directly reduce methanogens and hydrogen production in the rumen. Some oils such as linseed, coconut, garlic and cotton oil are considered to be amongst the most effective additives for methane mitigation.

Which animal produces the most methane?
