Bucking horse

Roughstock breeders have long established strings of bucking horses with broodmares and stallions that have been bred and crossbred to more consistently produce the desired temperaments and athletic ability needed for bareback and saddle bronc competition.

The term comes from the Spanish language word bronco meaning "rough" (adj), or "gruff" (n), which in Mexican usage also describes the horse.

Some are specifically bred for bucking ability and raised for the rodeo, while others are spoiled riding horses who have learned to quickly and effectively throw off riders.

Informally, the term is often applied in a joking manner to describe any horse that acts up and bucks with or without a rider.

While researching, he noticed the recurrence of Sankey's foundation bucking horse sire, "Custer", who died in 1994.

[17] Stone also discovered that some 30 head of the bucking horses used for the 1996 National Finals Rodeo (NFR) were descendants of Custer, and at least 15 were provided by Sankey.

Custer was thought to be sired by Gray Wolf, one of the stallions in the Tooke's bucking horse string.
