Founded in 1853 in South Texas, King Ranch spans 825,000 acres and has been a pioneering force in livestock genetics and agribusiness for over 170 years. It developed the Santa Gertrudis cattle breed, the first beef breed created in the U.S., known for heat tolerance and adaptability, which has influenced global cattle breeding. The ranch also created other notable breeds like Santa Cruz and American Red, combining traits for productivity, heat resistance, and meat quality. King Ranch’s integrated operations include cattle ranching, Quarter Horse breeding—highlighted by influential sires such as Old Sorrel—and large-scale agriculture, producing cotton, citrus, grains, and more, ensuring economic stability and continuous innovation.

King Ranch’s impact extends beyond genetics to shaping livestock production systems and environmental conservation practices. Its Quarter Horses are renowned for their strength and versatility in ranch work and competitive disciplines. The ranch’s data-driven genetic programs have improved fertility, longevity, and profitability, with many animals achieving top USDA meat quality ratings. As a historic and technical benchmark, King Ranch continues to influence modern agribusiness while preserving traditions established over nearly two centuries.
