The scientist said that after years of tests on mice, they managed to create in 2003 the first cow that could produce milk with the same nutritional properties as human breast milk "but with a taste even stronger and sweeter".
"The genetically modified cow milk is 80 percent the same as human breast milk," said lead researcher Li Ning.
"Our modified cow milk contains several major properties of human milk, in particular proteins and antibodies good for health and able to improve our immune system." Over 300 cloned cattle are now at an experimental farm in Beijing.
The researchers said an affordable form of the milk could be marketed within three years. Before that, however, strict safety tests are needed, Li said.
"In fact, we still need to conduct clinical trials on human beings with volunteers and finally prove that the cow milk is good and safe for the elderly, infants and the ill, especially those suffering from chronic diseases," Li said.
