Methane production and estimation from livestock husbandry: A . . . Wall et al , 2010 modeled that 21% less CH 4 emissions per kg of milk production would be possible after selecting a cow herd having 17% higher yield per lactation, and 14% higher gross efficiency Likewise, increasing the efficiency of meat production decreases emissions per unit of yield
6 Pressing Questions About Beef and Climate Change, Answered If ruminant meat consumption in high-consuming countries declined to about 50 calories a day, or 1 5 burgers per person per week — about half of current U S levels and 25% below current European levels, but still well above the national average for most countries — it would nearly eliminate the need for additional agricultural expansion

This Swiss cow feed could cut livestock emissions | World . . . A single cow produces the equivalent of about three tonnes of carbon dioxide per year, says Agolin, based in Biere near Lausanne Co-founder and managing director Kurt Schaller told Reuters its specialist feed can reduce that by 10 percent
Methane - Climate Change: Vital Signs of the Planet A molecule of methane traps more heat than a molecule of CO 2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO 2 can persist for hundreds of years or more Methane comes from both natural sources and human activities An estimated 60% of today’s methane emissions are the result of human activities
Gassy Cows Warm The Planet. Scientists Think They Know How To . . . Cattle pass a lot of gas, and the methane from their flatulence and especially, their belches, is an expanding burden on the planet The greenhouse gas has a warming potential 25 times that of carbon dioxide Livestock account for 14 5 percent of all greenhouse gas emissions, with over half of that
