Valley Equine, a horse breeding facility located near Stephenville, Texas, is at the forefront of the performance horse industry. This facility houses a significant number of horses, with over 100 present during a visit in October, a number that swells to over 300 during the peak breeding season. The primary purpose for most horses at Valley Equine is breeding, with the facility handling every stage from conception to birth and the sale of yearlings.
The process at Valley Equine is a sophisticated form of equine artificial insemination, involving the collection of eggs from mares and semen from stallions to create embryos. These embryos are then transferred to surrogate mares. This method is fundamental to the breeding of most competitive performance horses today, including those excelling in cutting, reining, and barrel racing. The genetic material produced at Valley Equine is in high demand globally, with embryos, semen, eggs, and yearlings being shipped to Europe and Australia. General manager Lisa Szwejbka notes that overseas breeding seasons complement the North American season, allowing for year-round activity in the industry.
While October is considered “sales season” and not the prime breeding period in Texas, the facility still hosts numerous horses. Some of these are pregnant mares, fulfilling their role in the breeding cycle. Even horses that are no longer in active training for competitions remain vital to the operation.
A notable resident at Valley Equine is Metallic Cat, the 2008 Futurity champion. His offspring have accumulated over $63 million in winnings, making him the second-highest earning sire, trailing only his own father, High Brow Cat. Metallic Cat’s influence is so significant that the Futurity World Championship is officially named the NCHA Metallic Cat World Championship Futurity. The value of his genetics is immense, exemplified by a Metallic Cat embryo that sold for a record-breaking $64,000 in late December 2024. Szwejbka articulates the business logic behind such practices: “If you know something’s going to potentially win you money and do well and be successful, why would you not create it?”
Valley Equine places a strong emphasis on the genetic health of its horses. Beyond meticulously researching bloodlines, the facility conducts tests for potential genetic disorders. Szwejbka mentions that Quarter Horses and Arabians can be prone to certain issues. To mitigate this, Valley Equine sends samples for an equine disease panel to institutions like UC Davis and the American Quarter Horse Association (AQHA). The results help clients make informed decisions about breeding based on whether the horses are carriers of genetic conditions.
The American Quarter Horse: The Premier Cutting Horse
The stables at Valley Equine primarily house cutting horses, which are almost universally American Quarter Horses. These horses are renowned for their “cow sense,” a crucial attribute for cutting competitions. Szwejbka describes Quarter Horses as not only strong but also exceptionally intelligent, capable of adapting to various situations and even outsmarting their handlers at times. Physically, they are not excessively tall, making them more manageable for riders. Their breeding for cattle handling has instilled in them the trainability, speed, and agility essential for cutting.
A source of great pride for the Valley Equine team is witnessing the success of horses they’ve been involved with from their early stages. Seeing horses they knew as embryos or yearlings compete and win in performance events is a testament to their work. When competitors’ horses bear the lineage of Valley Equine’s stallions or mares, the staff feel a personal connection, referring to them as “our baby.” A significant portion of the recognized successful horses carry their genetics.
