Huge, genetically modified cows that were created using rat genes have brought howls of protests at a local farm.
Standing at over three metres tall and weighing as much as five tonnes, each cow can produce around 180 litres of milk a day.
The mega cattle were initially conceived to get round EC milk quotas, which are based on the number of heads in a herd. But despite quotas being phased out the moo-sive cows are gaining popularity, this time as a simple show of farming might.
The cows were produced by China’s burgeoning biotech sector, combining genes from a regular Holstein-Friesian cow and a rat. “Rats have an amazing property: they never stop growing”, explained head of research at Deng Bio, Dr Wei Tsao. “By combining this trait with the highly productive Holstein, we have created an enormous cow with lucrative udders.”
