As a primitive breed unique to the Qinghai-Tibet Plateau, the yak is an important means of production and source of livelihood for the people living in the plateau area. In our country, there are about 14 million yaks, 92 percent of the total world population, distributed mainly over alpine grassland of about 157 million hectares on the Qinghai-Tibet Plateau. Since the end of the 1950s, with Professor Cai Li as a representative, a group of scientists from the Southwest College for Nationalities have conducted scientific research on yaks. They also examined the scientific and technological development of yak production in the alpine pastoral area at more than 4000 meters above sea level. They have achieved important outcomes and won acclaim from all over the world. In 1987, The Southwest College for Nationalities was the first in the country to recruit post-graduates to study ＂yak genetic breeding＂ in order to produce new generations for our yak studies. After 20 years the students have already made outstanding contributions to the development of the breed.
