Scientists cook up cure for cow flatulence

Cows belching and breaking wind cause methane pollution but British scientists say they have developed a diet to make pastures smell like roses, almost. “In some experiments we get a 70 per cent decrease (in methane emissions), which is quite staggering,” biochemist Dr John Wallace told Reuters.

Dr Wallace, the leader of the microbial biochemistry group at the Rowett Research Institute in Aberdeen, says the secret to sweeter-smelling cows is a food additive based on fumaric acid, a naturally occurring chemical essential to respiration of animal and vegetable tissues.
