3 'super cows' that can each give 100,000 litres of milk cloned, claims China

China has claimed successfully cloning three 'super cows' that could give 100,000 litres milk each in their lifetimes. The three calves, bred by scientists from the Northwest A&F University, were born in China's Ningxia region. Only five in 10,000 of common cattle breeds in China can produce as much milk as a super cow, the scientists said.
