About IYAK

International Yak Association

The mission of the International Yak Association:

·  To record yak pedigrees in the North American Yak Registry (NAYR)

·  To preserve and protect the genetic integrity of yak in the Herd Book

·  To advance awareness of yak

·  To educate its members in best management practices

IYAK and the North American Yak Registry (NAYR) were formally organized in 1992. IYAK was incorporated in the State of Oregon in 1995 and is a 501(c)(5) corporation. The first Certificate of Registration in the NAYR herdbook was issued in 1992 with the designated number of C001. There are now more than 1,700 registered yaks in the herdbook.

IYAK holds its annual meeting in January at the National Western Stock Show in Denver, Colorado. Members from around the world gather to compete in shows, attend seminars, share in the camaraderie,  and meet new friends.

Yak Registration

IYAK’s primary mission is to maintain and register yaks to the NAYR herdbook. Offspring of registered Foundation yaks may be registered to the Foundation herdbook via application to the registrar. Yaks from unregistered parents may be registered to the Foundation herdbook if approved by the Registration Committee.


DNA samples are required from all animals.DNA testing is used to fingerprint the animal, verify parentage and determine if the animal is a hybrid and therefore not eligible to be registered in the NAYR herdbook.
