Chinese scientists gave birth to a cloned yak by Caesarean section

A cloned yak was born by Caesarean section at a yak breeding center in Damxung County, Xizang Autonomous Region, southwest China .

According to researchers, the calf, born on Thursday, weighed 33.5 kilograms (75 pounds), making it heavier than most yak calves. The calf, which has a completely black coat, was able to walk a day after birth and appeared to be in good health.

The cloning project, a joint effort between Zhejiang University, the Damxung County government, and the Xizang Autonomous Region Plateau Biology Institute, was launched in July 2023. Scientists successfully produced cloned yak using whole-genome selection and somatic cell cloning technologies.

Cloning technology will play an important role

Fang Shengguo from Zhejiang University, who led the project, said cloning technology will play an important role in improving yak breeds and establishing a sustainable breeding system in high-altitude areas in Xizang.

Yaks, which live only on the Qinghai-Xizang Plateau, are not only the main source of livelihood for herding communities in the region but are also considered an indispensable part of the ecosystem.
