Zoologists in Tibet have launched an embryo transplant program to preserve and improve the genetic quality of yaks, a species native to the Qinghai-Tibet plateau, China Radio International reported on Monday.

   
The Tibet Regional Academy of Agriculture and Animal Husbandry is using cutting-edge technology to transplant embryos from top quality female yaks specially raised in the wombs of other yaks to ensure the quality of the calves.
   
Dr. Ji Qiumei, who heads the research program, says it is the first time for embryo transplant technology to be used on yaks. It has already been used to reproduce oxen, sheep and goats in China.
   
She expects the research will help preserve the rare highland species, improve its pedigree and thus boost local animal husbandry.
   
The Qinghai-Tibet plateau, known as the "roof of the world", is home to about 14 million yaks, 95 percent of the world total.
   
The Tibetan yak, formerly used for transportation, is now raised more for the wool, dairy and meat processing industries.
