Chinese scientists have claimed to have succeeded in cloning a cow with genes resistant to mad cow disease.

The 55 kg calf was born in Shandong Province, three years after the disgraced scientist Hwang Woo-suk (South Korea) cloned cows with a protein structure resistant to mad cow disease.

" Scientists at Laiyang Agricultural Science Institute in Shandong said they used gene transfer technology to put these important genes into a calf, cloned from an adult cow cell ," Tan said. Hua Xa reported.

Subsequent tests will test whether the calf is stable and maintains the effectiveness of the transplanted gene.
