Chinese scientists have genetically modified dairy cows to produce human breast milk, and hope to be selling it in supermarkets within three years.
The milk produced by the transgenic cows is identical to the human variety and has the same immune-boosting and antibacterial qualities as breast milk, scientists at China's Agricultural University in Beijing say.
The transgenic herd of 300 was bred by inserting human genes into cloned cow embryos which were then implanted into surrogate cows.
The milk is still undergoing safety tests but with government permission it will be sold to consumers as a more nutritious dairy drink than cow's milk.
"It's good," said worker Jiang Yao. "It's better for you because it's genetically modified."
