Major breakthrough made in panda breeding technology

THE world's first panda cub bred using a new freezing technique in artificial insemination was born yesterday in Sichuan Province, marking a major breakthrough in breeding technology for the endangered animal.

You You, 11, gave birth to the cub at Wolong Giant Panda Nature Reserve around 7.40am yesterday. It was the seventh panda cub born this year at the reserve and the 10th in the world, West China City Daily reported today.

The cub is doing well, researchers told the newspaper.

Researchers artificially inseminated You You on March 20 with semen from Lu Lu, a male panda at the reserve. The semen had been frozen for a period of time and then thawed for the procedure. You You was confirmed pregnant in early June.

Researchers told the newspaper artificial insemination is often used to breed giant pandas as the species has trouble reproducing, but that in the past they always used fresh semen.
