Located in the Violet Crown of Texas, on the rolling hills and prairies of Lampasas County, The Swannderosa (SDR) Ranch is family-owned and specializes in high-quality Santa Gertrudis cattle. We take great pride in breeding and raising our cattle, applying modern science to an old profession in order to improve the Santa Gertrudis breed. All of our breeding stock is DNA tested to help ensure the accuracy of the Expected Progeny Differences (EPDs), and we utilize this information in our breeding program.
