Beefalo are the fertile offspring of (usually) a domestic bull and an American bison cow. While crossing a domestic cow and a bison bull can produce offspring, they are few in number.

The beefalo is a fertile hybrid of beef cattle and American bison (buffalo), with the result being mostly cattle in appearance and genetics. Its origin was the cattalo of Charles “Buffalo” Jones who created the first bison hybrid. The intention was to make hardier cattle to survive harsh winters as well as to preserve bison, most of which today have a small percentage of cattle genes. Beefalo color takes after the cattle which can be any of the breeds used for the crossing, and the result is better milk than that of the bison and meat which is leaner than that of beef.

4 Incredible Beefalo Facts!

• Full Beefalo must have exactly 3/8 American bison genetics; if higher, it’s a bison hybrid.
• The origin of the Beefalo was the first fertile hybrid bull from a domestic bull and an American bison cow, which produced several offspring with fertile females but rarely-fertile males.
• Beefalo meat is lower in calories, fat, cholesterol and saturated fat and higher in protein than beef.
• The origin of hybrid bovids was in 1749 with the accidental crosses of cattle and American bison in the southern United States, but intentional crosses began in the mid-19th century.

Beefalo Scientific Name

The scientific name for Beefalo is Bos taurus × Bison bison. Like both domestic cattle and American bison (buffalo), it is in the family Bovidae, subfamily Bovinae, tribe Bovini, and subtribe Bovina. Domestic cattle are Bos taurus and American bison are Bison bison, with subtribe Bovina containing the two living genera Bos and Bison. Bos is the genera for wild and domestic cattle and contains 5 species, while the genera Bison contains 6 extinct and 2 extant species. Although American bison and domestic cattle are from both a different genus and a different species, they have enough genetic similarities for several domestic cattle breeds to produce fertile offspring with American bison.

Beefalo Appearance

Beefalo can come in a variety of colors, with the color taking after the domestic cattle used to cross with the American bison. There is no standard color, but a dark black/red to light fawn is common. Its size and appearance resemble the cattle while the cattle also predominates its genetics, weighing 900 to 2,000 pounds and reaching up to 55 inches in height. It is classified as a USDA-recognized cattle breed and is different from a Bison Hybrid or Cattalo, which both have more American bison genetics. Hereford, Angus, and Holstein cattle are common in crossing with bison, but the cattle parent can also be a mix of different breeds, including breeds from other countries, in order to promote genetic diversity.

Beefaloes differ from bison in that they lack the hump. They have fine, dark hair evenly covering their bodies. Bison are hairier and have curved, larger horns, but beefaloes may be either horned or polled. If they are horned, the horns are long, tapering, and pointed upwards.

Beefalo Behavior

The behavior of American bison-cattle hybrids depends on the amount of bison genetics they contain. For beefalo, they are most similar to cattle in appearance, behavior, and genetics. If they further interbreed with American bison, the resulting offspring will behave more like the bison parent. Bison are more aggressive than cattle and wander more, whereas cattle stay around trees and water sources. Beefalo are more docile and have about 12 members in a herd. Whereas bison naturally group together cows and calves with bulls in a separate herd, beefalo farmers separate bulls from cows and calves until breeding time. The breed of domestic cattle parent the beefalo can also determine behavior, as heavier milk cattle are dominant to lighter milk breeds, and lighter meat cattle are dominant to heavier meat breeds.

Beefalo Habitat

Beefaloes live in North America. However, they are only available from farmers registered with the American Beefalo Association. Although they originated in Kansas, which has extremely cold winters, they can handle both extreme heat and cold.

Beefalo Diet

Unlike cattle, beefaloes need little to no grain feeding. They can survive on a wide variety of grasses in both very hot and very cold weather and less grass than cattle, making them ideal for both harsh weather and rough or weathered vegetation.

Beefalo Predators and Threats

The beefalo is far hardier and disease-resistant than domestic cattle, being resistant to Bovine Viral Diarrhea, Bovine Respiratory Complex, and Blackleg. They do not need to be vaccinated as often as cattle, either. Humans are its only natural predators as they developed the beefalo under-managed breeding programs for consumption of milk and meat and use of manure.

Beefalo Reproduction and Life Cycle

The beefalo parents of American bison and cattle are bred in managed breeding programs to create hybrid offspring. Fertile cow hybrids are then bred with fertile bull hybrids.

Beefalo can be produced naturally or artificially (via insemination or insertion of a fertilized embryo). The gestation period is between 279 to 287 days with an average of 283 days, with bull calves having gestation periods that are a little longer than heifer calves. Beefalo calves are very small after being born and weigh an average of 40 to 60 pounds, but grow to weigh 800 to 1,000 pounds at 9 to 12 months instead of the 12 to 14 months of the cattle. They reach sexual maturity a little later than domestic cattle while being able to reproduce until 25 years of age compared to 8 to 10 years. Beefalo calves are weaned at 205 days and reach sexual maturity within 6 to 15 months.

Unlike cattle, beefaloes have no calving problems and they grow faster, needing no growth hormones thanks to the bison genetics. They also produce more and richer milk than either cattle or bison, being richer in butterfat and with a sweeter, creamier taste. Their meat is also just as flavorful and tender, making them equally good for milk and meat.

Cattle can live up to 25 years and bison can live up to 20 years. The beefalo’s lifespan is at least 20 years, with its hardiness making it likely to live 25 years or more.

Beefalo Population

Beefalos are considered an invasive species as they behave more like cattle and can pollute water sources, negatively affecting biodiversity and the cleanliness of their environments. They can also naturally cross with bison to create more aggressive bovid hybrids and pollute the gene pool of the few remaining pure bison herds.
