Decide whether to breed for your bulls or to purchase as calves. If you plan to breed, research the bloodlines of available bulls and have your cows bred to the bulls of your choice. If you plan to purchase the calves, attend livestock auctions or approach known breeders to buy desired animals.
Turn calves out on pasture or available land, making sure they receive proper nutrition and exercise. Adequate exercise will be a priority for bulls throughout their competitive careers, just as with any athlete.
Begin to chute train bulls around two years of age. According to Allan Jordan, a Pro Official with the PRCA and former livestock manager Rodeo Stock Contractors, you should bring young bulls into the chutes and begin to handle them so that they become accustomed to standing in chutes and being touched. Turn the bulls loose into arena and move them from arena to holding pens. Continue to work the bulls until they are comfortable with the process and not so wild that they could injure themselves. During this process, flank the bull for the first time. The flank is a piece of rope tied loosely around the flank area of the bull to encourage a higher buck.
Buck the bulls using mechanical dummies once they are comfortable with arena procedures. Dummies are strapped to the back of the bull and released using a remote. A dummy should be released as soon as the young bull makes a good move to reward him and help teach him how to buck.
Buck young bulls with a real rider at home if your arena conditions allow. Bulls should be about four years old before riders are used to ensure they are big enough to carry the weight.
Haul young bulls to competitions. There are many competitions for young bulls today using mechanical dummies. Using bulls in actual bull riding competitions with riders is useful as well in limited outings.
Judge the ability of the bull when it is about 4 or 5 years old. For pure economics, your herd should be culled to just the best bulls. To continue on to rodeos and bull riding events, the bull must prove his worth to the stock contractor or producer of the events. Develop relationships with these individuals to continue to have venues where you can buck your bulls once they grow past aged events.
