Unlike most breeds of cattle, no one set out to develop Texas Longhorn cattle as a breed. Instead, they evolved in North America from descendants of cattle brought into the Americas by the Spanish in the late 1400s and early 1500s (the first cattle were brought into Hispaniola in 1493). However, the cattle did not descend directly from Spanish stock. Rather, the first cattle to be imported by the early Spanish explorers were from the Canary Islands. These cattle, in turn, were imported from Portugal, and the closest relatives of Texas Longhorns among existing European breeds are Portuguese cattle breeds (such as the Alentejana and Mertolenga). These early imports of Iberian cattle from the Canary Islands soon became feral in northern Mexico (which included lands that became the Republic of Texas in 1836, and part of the United States in 1845). These wild herds underwent intense natural selection; the only cattle that could survive were highly disease resistant, could live on harsh range conditions (through droughts, floods, heat, and cold), and could defend themselves and their calves against predators.
During the late 1800s, large ranches began to be established in Texas. Fences were built, cattle were captured and contained, and the days of free-ranging cattle came to an end. Although these ranches originally kept Texas Longhorns, most soon turned to importing "improved" European breeds of cattle. The European breeds produced much more fat than did Texas Longhorns, and tallow was the primary driving force behind cattle prices at the time. However, several ranchers kept herds of the original Texas cattle, either for nostalgia or because they appreciated the abilities and qualities of these cattle. By the 1920s, the longhorned cattle were rare enough that the United States government paid to assemble a herd of Texas cattle at the Wichita Wildlife Refuge in southwestern Oklahoma, to preserve them from extinction. About a half-dozen private herds were also maintained through (or started in) the first half of the 1900s, and most modern Texas Longhorns can be traced back to these seven "families"of longhorns (the Wichita Refuge, Butler, Marks, Peeler, Phillips, Wright, and Yates lines).
In 1964, the Texas Longhorn Breeders Association of America (TLBAA) was founded, and a registration process was established. Thus, Texas Longhorns became a registered breed. Today, Texas Longhorns are bred and valued for many different reasons. Their naturally lean meat is now considered an advantage, and the ability of Texas Longhorns to thrive on natural range conditions (without the use of antibiotics, added hormones, or the use of feedlots) makes them a favorite for the lean beef, range-fed beef, and organic beef markets. They are also widely raised for their beautiful colors and horns, and by people who appreciate the history and qualities of the breed. Texas Longhorn bulls are often used as service sires on other breeds of cattle, because the crosses produce fewer birthing difficulties and calves that grow quickly and have few health problems. At the Double Helix Ranch, we were attracted to Texas Longhorns because of their high genetic diversity and associated high fitness, in addition to their historical interest and their beauty. Traits that stand out in Texas Longhorns are their natural disease resistance, great longevity, high reproductive rate, ease in birthing, ability to thrive under harsh range conditions, and an ability to defend themselves against predators. We have never lost a single Texas Longhorn calf to disease or predation, and they thrive without extensive care or supplemental feeding.
For more detailed information on the history of Texas Longhorn cattle, I recommend T. J. Barragy’s excellent book, Gathering Texas Gold, in addition to J. Frank Dobie’s classic book, The Longhorns.
