The Irish Black Breed Information

The breed that meets the consumer's demand for quality beef...

The Irish Black Breed has its roots in a genetic theory promoted by world-renowned Iowa State geneticist, Dr. Jay Lush, in the 1930s. Dr. Lush maintained that consistent quality would best be achieved through a concentrated gene pool developed in the process of line breeding.

Colorado cattleman, Maurice Boney, studied under Dr. Lush and decided nearly 50 years ago to adopt Lush's genetic theory, in spite of the fact that the beef industry as a whole moved toward crossbreeding practices.

In 1971, Boney imported a purebred Friesian bull from Ireland and mated him to Angus females coming from the Old Revolution bloodline. Old Revolution was known in the 1940s and 1950s as fertile and hardy, with consistent performance. The cattle were also known to possess "feeding capacity," meaning they efficiently converted forage into quality beef. Boney wanted to establish those traits in his own cattle.

In a carefully planned and implemented breeding program, Boney continued to cultivate the best traits in his closed herd, resulting in a herd of cattle that were 98% pure Friesian blood. Consistently high quality carcass traits was one of the outstanding characteristics of the cattle.
