Thus, in 1994, Tallman created the Rodeo Stock Registry (RSR) as a genetic database. The intent was to allow breeders to track the pedigrees of notable bucking bulls, and thus prove parentage of offspring. When the RSR became available, breeders such as Wilfong started using it to register his bulls and manage his program. He used the RSR to calculate that he had 16 different bloodlines in his pedigrees.
