The Texas Longhorn is a cattle breed which is distinguished by its exceptionally long horns and its ability to survive in hot, sparse terrain with little supplemental feed. The Texas Longhorn was developed in southern Texas in the early 1800's, and is a descendant of Spanish, English and Mexican cattle.
Crossbreeding Texas Longhorns and Herefords is done to increase hybrid vigor and to improve calving.
