Using modern plant-breeding methods to find new diets for cows that make them belch less is a way to reduce greenhouse gas emissions, scientists reported this week.

He noted the average dairy cow belches out about 100 to 200 litres of methane each day, making diet changes a key potential factor in reducing this greenhouse gas.

"There is a common misperception about how methane gets into the atmosphere," he said. "It is actually through belching rather than the other end."
