American Wagyu Association

The American Wagyu Association is a breed association for cattle. Wagyu refers to all Japanese beef cattle. In 1976, two Wagyu cattle were imported in the U.S. This was the only importation of Wagyu cattle until 1993.

What are Wagyu?

Wagyu – a Japanese beef cattle breed – derive from native Asian cattle. 'Wagyu' refers to all Japanese beef cattle, where 'Wa' means Japanese and 'gyu' means cow. Wagyu were originally draft animals used in agriculture, and were selected for their physical endurance. This selection favored animals with more intra-muscular fat cells — ‘marbling’ — which provided a readily available energy source. Wagyu is a horned breed and the cattle are either black or red in color.

Wagyu Breed History in Japan

There is some evidence of genetic separation into the Wagyu genetic strain as much as 35,000 years ago. Modern Wagyu cattle are the result of crossing of the native cattle in Japan with imported breeds. Crossing began in 1868 after the Meiji restoration in that year. The government wanted to introduce Western food habits and culture. Brown Swiss, Devon, Shorthorn, Simmental, Ayrshire, and Korean cattle were imported during this period. The infusions of these British, European and Asian breeds were closed to outside genetic infusions in 1910.

The variation of conformation within the Wagyu breed is greater than the variation across British and European breeds. The three major black strains — Tajiri or Tajima, Fujiyoshi (Shimane) and Kedaka (Tottori) evolved due to regional geographic isolation in Japan. These breeding differences have produced a Japanese national herd that comprises 90 percent black cattle with the remainder being of the red strains Kochi and Kumamoto.

Wagyu Breed History in the U.S.

Wagyu cattle were first imported in 1975, when two black and two red bulls were imported by Morris Whitney. In 1989, the Japanese began to reduce their tariffs on imported beef, which encouraged U.S. producers to produce a high-quality product for Japan. In the 1990’s, there were several importations of quality Wagyu. Most were black, but a few were red Wagyu. These cattle have the greatest influence on the U.S. herd and those in many other countries.

Most U.S. production was exported to Japan until 2003, when BSE was discovered and Japan and other countries stopped the import of beef for the U.S. However, chefs and others in the U.S. were aware of the superior eating quality of Wagyu, and the domestic market then and now utilizes much of the U.S. production.

Wagyu Beef — Delicious and Healthy

The unique taste and tenderness of highly marbled Wagyu beef makes for an unrivalled eating experience. That is why Wagyu beef is finding its way into the repertoires of gourmet cooks and fine restaurants across the U.S.

Not only is it a gastronomic delight, but it’s healthy, too. Health experts have discovered the mono-unsaturated to saturated fat ratio is higher in Wagyu than in other beef, and the saturated fat contained in Wagyu is different. Forty percent is in a version called stearic acid, which is regarded as having a minimal impact in raising cholesterol levels. The profile of marbled Wagyu beef is more beneficial and healthier to human health.

Wagyu is also higher in a type of fatty acid called conjugated linoleic acid (CLA). Wagyu beef contains the highest amount of CLA per gram of any foodstuff — about 30 percent more than other beef breeds — due to higher linoleic acid levels. Foods that are naturally high in CLA have fewer negative health effects.

U.S. Wagyu Today

The American Wagyu Association was incorporated in Texas on March 14, 1990, and serves to register Wagyu cattle in the U.S., Canada and other countries. The Association headquarters are based in Post Falls, Idaho. The Association has a vibrant membership base and continues to promote and develop a sustainable industry here in the U.S.

The opportunities Wagyu beef can offer are endless. This industry caters to the breeder/feeder, targeting the high-end restaurant trade with highly marbled beef to the bull producer, supplying the cow/calf rearer a crossbred alternative that will offer calving ease ability and premium carcass quality in a single cross, which no other beef breed can come close too.

The Wagyu breed has a vital role to play in the U.S. to increase the quality of red meat produced in the U.S. that our health conscious consumer of the 21st century is forever seeking.
