A bucking bull is a bull used in rodeobull riding competition. They are usually a Brahman crossed with another breed, weighing 1,500 pounds or more, selected for their tendency to "leap, plunge and spin" when a human is on its back.Шаблон:Sfn Circa mid-20th century breeders began selecting bulls for bad temperament, that would buck when ridden.Шаблон:Sfn
Many of the best bucking bulls trace their lineage to bulls owned by Charlie Plummer of Oklahoma. These are known as Plummer bulls.Шаблон:Sfn
Bucking bulls are viewed as athletes. They usually are started in their bucking career at the age of two or three, reach their athletic prime at age five or six, and if they remain healthy, can continue bucking at least until the age of 10, sometimes longer.[1]
In some competitions between bulls, with a purse amounting to tens of thousands of dollars per event, the bulls are ridden by electronic dummies, not rodeo bull riders.[2] Good performing bulls attain a celebrity status and can be considered a star athlete in their own right, and a valiant competitor on the field against the human rider.Шаблон:SfnШаблон:Sfn
The first sale of breeding cows out of champion bucking bulls was in 1999.[3]
The percent of top professional riders staying on the bull for a full eight second "out" had dropped from 75% in the early 1990s to 35% circa 2014. This has led to criticism that the breeding has resulted in excessively aggressive and dangerous animals.[4]
