Originally started as the Rodeo Stock Registry by Bob Tallman in 1994, American Bucking Bull Inc. is the official DNA registry for the bucking cattle industry. Formed in 2004, ABBI has since realized one of its key objectives of documenting the bloodlines of the most well-known and influential bucking bulls in the world. By preserving the genetic lineages of these elite bucking bovines through future generations, each year ABBI continues to register the descendants of the most famous bucking bulls of all time.
