Great Plains Breeder Services has been a trusted provider of livestock reproductive services for decades, serving cattle producers with advanced technologies, expertise, and a commitment to improving herd genetics.
Great Plains Semen Service was established in the mid-1970s. After a company reorganization, the Great Plains Breeder Services facility was constructed in the early 1980s to serve seedstock producers across Texas, Oklahoma, and New Mexico. At the time, the closest bull collection facilities were located in Fort Collins, Colorado and Elgin, Texas.
Great Plains Semen Service was established in the mid-1970s. The organization began providing semen collection services for cattle producers across the region.
Dr. Russell Killingworth joined Shamrock Veterinary Clinic as an associate veterinarian. During this time the team began performing conventional embryo transfers and implementing new technologies to improve sample evaluation and recording.
The facility expanded with the construction of an air-conditioned barn to help maintain optimal collection conditions during summer heat. Additional laboratory equipment and evaluation tools were added.
Dr. Jim Bob Nall was hired as an ambitious veterinarian and began overseeing custom collections while the business expanded into international semen shipments and embryo transfer services.
Jim Bob and Diana Nall purchased Great Plains Breeder Services. The company continued expanding services and integrating modern technologies such as IVF, advanced genetics programs, and partnerships with industry leaders.
As cattle breeding technology advanced, Great Plains gained the opportunity to collect and ship genetics worldwide. The organization worked with well-known sires and expanded its services to support producers seeking elite genetics and improved herd performance.
The formation of organizations such as the Professional Bull Riders (PBR) increased demand for genetic collection from bucking bulls, further expanding the company’s role in livestock genetics.
In 2023, a group of industry leaders including Tony Small of Flying Cow Genetic, Kevin Green, and Zeb King joined forces to purchase the company. Their goal is to merge decades of experience with modern technologies such as in-vitro fertilization and advanced data management systems.
Great Plains now serves as an ABS collection facility on the embryo and IVF side, maintaining the highest standards for semen quality and genetic evaluation.
Great Plains Breeder Services continues to build on decades of expertise while embracing the technologies shaping the future of livestock reproduction. The company remains dedicated to supporting cattle producers with reliable services, innovative techniques, and a commitment to excellence.
