Bullnanza Stud Services is proudly owned by Kolten Thigpen and Jason Holder. Jason was the visionary behind the business. Having provided the Sweetwater, Tx area with semen sales and club calf sales in recent years, Jason saw the need for a bull collection facility in the area. His employer and Kolten's Father-in-Law, Tom Rees, had the perfect facility in the perfect location.  So when Reproduction Enterprises Inc reached out to us about being a semen processor for our facility, the business began! We are proud to be your West Texas source for everything bulls; whether it be semen collecting, semen sales, or bulls sales and leases, we are here working for you. We maintain an unrelenting standard of excellence, to help your program reach its goals. Bullnanza Stud Services, where dreams are conceived.
