EVERYDAY SCIENCE

Detailed explanation-1: -with an uncertainty of about 15%. Of this, cattle contribute about 74%. Buffalos and sheep each account for 8-9%, and the remainder stems from camels, mules and asses, pigs, and horses. Human CH, production is probably less than I Tg per year.

Detailed explanation-2: -Cows burp major amounts of methane, a greenhouse gas that is dozens of times more potent than carbon dioxide. Their digestive system makes them produce considerably more methane than pigs, chickens or turkeys do, Eshel said. The manure used to grow feed for cows also releases methane, as does their own bodily waste.

Detailed explanation-3: -The agricultural sector accounts for an estimated 40 percent of human-caused methane emissions. Reduction strategies include preventing the burning of fields after harvests, adjusting feed for livestock so that they release less methane, and regularly draining rice paddies. Fossil fuels.

Detailed explanation-4: -Grinding and pelleting of forages increases passage rate and reduces methane emitted by the animal. Fats are a high energy source that can be included as part of the diet and have been shown to have an inhibitory effect on methane production as fat can be toxic to methane producing microbes.
