The origin of Mongolian yak
• The paleontological findings related to yak origin , found uptill now, are
30-40 thousand years ahead and it shows that wild yaks have been
distributed from Central Asian platue to North America, covering vast
land.
• Archeological findings have proved that Mongolians have been breeding
yaks since 2500 years ago. Historian G.Sukhbaatar has noted that
Khunnu state had 6 types of livestock one of which was a yak.

• The heat in yak cows lasts for 18 hours. 70-75% of cows
become pregnant after the first heat. A bull serves for 15-20
cows in natural breeding season. A yak sire is used for
breeding for 2.5 – 8 years. An yak cows calve 6-8 time.
• Regarding the yak breeding, herders used to select yak
bulls for breeding purpose by considering their body
conformation and coat color.
• In high mountain region, young sires of dark coat color with
a good body conformation are preferred. The sires with
these features usually do not suffer much from loose of their
liveweight during winter-spring time. To prevent from
inbriding, herders used to exchange sires frequantly.

In high mountain area, yaks and their hybrids, mainly F1 are used as a means of
transportaion (packing and riding in card). (Difficult to reach by car and tractor) In winter
and spring yaks also are rided.

Future development of Yak farm
A plan for supporting the forming of nuclear herds from meat and milk
type yaks in the provinces located in high mountain region is developed.

Yak wool value chain development
1 step: Raw material preparation
• Herders are learning to comb yak down
• Price per kg increased from 1/3 USD to 5 USD in 5 years.
2 step: Brand development

• Represents a production code with no harmful
effects on ecological and social well being of
rangelands and herders.
• 20% of added value profit is distributed to
herders.
• Produced by herders maintaining their pastures
healthy.
• Produced from finest quality camel and yak wool.
