London:  Now cow milk having the same nutritional value as that present in human milk has been made possible by a group of scientists of China Agricultural University.

They for the first time have produced genetically modified cattle which milk has the same properties as human breast milk.

This team of scientists has successfully introduced human genes into 300 cows to produce "human" milk which is known to contain high quantities of key nutrients that can help to boost the immune system of babies and reduce the risk of infections.

Milk from these genetically modified cows could provide an alternative to human breast milk.

Proffesor  Ning Li, the scientist who led the research has said their work has shown it was possible to "humanize" cows' milk which would be as safe to drink as milk from ordinary dairy cows.

“The 'human-like' milk will provide much higher nutritional content. It tastes stronger than normal milk. We aim to commercialize some research in this area in coming three years,” he said.

In their research, the team used cloning technology to introduce human genes into DNA of Holstein dairy cows.

They said they were able to create cows which produce milk containing a human protein called lysozyme which protects infants from bacterial infections.

The scientists have also claimed that they have boosted milk fat content by 20 percent and have also changed levels of milk solids.

Helen Wallace, Director of biotechnology monitoring group GeneWatch UK, said, "We have major concerns about this research to genetically modify cows with human genes. There is a question about whether milk from these cows is going to be safe from humans."
