Behind the great flavor.

The International Yak Association exists for the purpose of advancing awareness of the Yak and for benefiting its members through education and communication. As Yaks are still quite rare on a national scale, we rely on our members to come together with their experiences and knowledge so that we may continue to learn about this multi-faceted bovine.

Yaks can fill the market niche of every cattleman, small acreage owner or exotic breeder. They provide a source of breeding stock, crossbreeding stock, meat, fiber, milk and dairy products, hides, horns, and make excellent pack or show animals.

The International Yak Association (IYAK) and the North American Yak Registry (NAYR) were formally organized in 1992 and are dedicated to the advancement of yak breeding. IYAK was incorporated under the State of Oregon in 1995 and is a 501 (c) (5) corporation.

The first Certificate of Registration in the National Association of Yak Registry (NAYR) was issued in 1992 with the designated number of C001. There are now more than 650 registered yaks in the US and Canada and their lineages are being tracked at the NAYR office. Photos must accompany each registration for yak identification and proof of percentage yak. Crossbreds may also be registered under a separate designation.
