By modifying cows to burp and fart less, scientists hope to cut the amount of methane emissions from cattle.
Methane, a greenhouse gas, is a large problem in the agricultural industry and the contribution from digesting cattle is a major source.
The rate of methane gas production has been linked to inherited gut microbes and if cattle were bred with these microbes in mind the cows would produce less methane.
Scientist John Wallace told Newsweekover 90 percent of the methane is burped. He went on to say there is the possiblity of cutting methane production by half.
