American Wagyu began with a bold idea combining Japan’s legendary Wagyu genetics with American ranching expertise. In 1976, the first Wagyu bulls arrived in the U.S., marking the beginning of a decades-long journey to create something extraordinary for the American Consumer..
Through careful crossbreeding with Angus and other American breeds, ranchers worked to balance the tenderness and marbling of Wagyu with the size and efficiency of traditional U.S. cattle. The results were remarkable: beef that carried the melt-in-your-mouth richness of Wagyu and the hearty flavor of Angus that you’ve come to expect.
In 1997, The Japanese Government banned all exports of live animals including semen and embryos after declaring Wagyu a National Treasure. This locked the genetics of the American herds to those imported in the 1976 and the early 1990’s. Because of this ban, these original genetics became even more valuable, pushing breeders to develop new ways of taking those genetics to the next level. By using artificial insemination and IVF techniques, these pure genetics were refined by selective breeding to replicate the most desirable traits to produce superior breeding bulls and heifers and then make available to any breeder the improved strains of the fullblood Wagyu. You find Fullblood breeders whose sole business model is developing the best genetic traits to help farmers and ranchers raise the best Wagyu meat possible, whether they raise Fullblood, American or both.Traits that truly define the quality of American Wagyu.
Today, there is estimated to be around 5,000 Fullblood Wagyu cattle in the county being utilized by American Wagyu breeders to further refine and better their herds. The combination of these two genetics continue to set the gold standard for premium “Better than Prime” beef.
