The Beefalo is a distinct breed of livestock resulting from the crossbreeding of domestic cattle (Bos taurus or Bos indicus) and the American bison (Bison bison). This hybrid was developed to combine the superior meat quality and handling characteristics of cattle with the rugged hardiness, feed efficiency, and disease resistance of the bison. The goal was to produce a more efficient and resilient source of meat that could thrive in varied environments. Beefalo meat is known for being lean, lower in fat and cholesterol compared to traditional beef.
Early and Accidental Crosses
The history of bison-cattle hybridization extends back much further than the registered Beefalo breed, with accidental crosses noted in North America as early as 1749. Intentional crossbreeding began in the mid-19th century, with figures like Robert Wickliffe starting experiments around 1815. These early hybrids were often referred to as “cattalo.” The primary motivation was creating an animal that could withstand severe North American winters, a need highlighted after events like the devastating blizzard of 1886.
Early attempts by settlers, ranchers, and the Canadian government faced significant biological hurdles. The first-generation male offspring were overwhelmingly sterile, severely limiting the ability to establish a self-sustaining herd. The Canadian government’s extensive program, which continued until 1964, had limited success overcoming this infertility barrier. These initial efforts demonstrated the hybrid’s potential but did not result in a commercially viable, fertile breed.
Achieving Genetic Stability
The breakthrough in creating a stable, fertile hybrid occurred in the mid-20th century, marking the true beginning of the Beefalo breed. In 1957, Montanan rancher Jim Burnett successfully produced a fertile hybrid bull. This achievement was important because the sterility of male offspring had been the primary obstacle for decades, and Burnett’s work provided the foundation stock for stabilization efforts.
The most notable progress was made in the 1960s and 1970s by Californian rancher D.C. “Bud” Basolo. Basolo utilized foundation animals, including Burnett’s fertile bulls, in a dedicated, multi-generational breeding program to select for consistently fertile animals. This methodical approach overcame the long-standing fertility issues. Basolo’s success in producing a herd of thousands of hardy, fertile bison-cattle hybrids in the early 1970s established the viable Beefalo breed.
Formal Breed Registration
Once genetic stability was achieved, the focus shifted to formally recognizing and commercializing the new animal. The name “Beefalo” was introduced in the early 1970s to distinguish this fertile, stabilized hybrid from the earlier, often sterile, “cattalo” crosses. The formal registration process began in this era, validating the animal as a distinct, standardized breed.
The establishment of early registry bodies, such as the American Beefalo World Registry, provided the framework for breed standards and documentation. Registration transformed the animal from a generic bison-cattle cross into a defined, commercialized product. This recognition was essential for breeders to establish pedigree and market the animal to the wider livestock industry.
The Genetic Composition
The defining feature of a registered Beefalo is its specific genetic makeup, which is mandated by the breed association. A registered “Full Blood” Beefalo must possess exactly 3/8ths (37.5%) American bison genetics and 5/8ths (62.5%) domestic cattle genetics. This precise ratio is required for the animal to be designated as Beefalo, regardless of the specific cattle breeds used for the remaining percentage.
This 3/8ths bison fraction was determined to be the ideal balance. It retains the bison’s desirable traits, such as hardiness and lean meat, while ensuring the animal is fully fertile and manageable like domestic cattle. Hybrids with a higher percentage of bison genetics are classified as “bison hybrids” or “cattalo,” which are often less fertile and more difficult to manage. The Beefalo designation refers to an animal bred to meet this exact genetic threshold, consistently producing a commercially superior animal.
