China creates world's first genetically modified cow

Chinese scientists have created the world's first genetically modified cow that can give milk rich in Omega-3 fatty acid, Xinhua reported.

"Two embryo-cloned and genetically-modified dairy cows were born June 23 last year. One of the cows has been found to have Omega-3 fatty acid level 10 times higher than a normal cow," said Li Guangpeng, head of the Biological Technology Laboratory at Inner Mongolia University.

"We did not announce the birth of the cows until now because it has taken time to check the cows' effective genetic traces," Li said.

He said it takes 14-15 months for a cow to become sexually mature, and another nine months to produce milk. The cows have been fed with normal cow feed.

Dubbed a "good fat", Omega-3 is an essential fatty acid necessary for human health. But it cannot be made by the human body. It is abundant in walnuts and cold water fish like herring, mackerel and sturgeon.
