Understanding Methane Production in Livestock

Methane emissions from livestock, secularly ruminants such as cattle, sheep, and goats, diment a signitant contributor to global greenhouse gases. Methane has a global warming potential approximatele 28 times that of carbon dioxide over a 100- year period, making its reduction a criticaat target for climate change compation. The primary source of methane in livestock is enteric fermentation, a digette process thatt existins ithe rumen - the largeste comment of the rumint.
