Most bulls are castrated to prevent any inferior genetics from being passed from him to the cowherd. Bulls that are inferior as far as ADG ability, temperament, forage convertibility, and conformation is concerned, should not be used for breeding. Also they can be quite aggressive and quite dangerous because of the testosterone levels.
You don't have to castrate them because they are genetically infertile, or cannot produce offspring.
Right away.
Bull calves. When they are weaned and/or reach around 10 months of age they are referred to as bulls or young bulls.
Calves are offspring of mature cows and bulls.
You can castrate a buck kid when you feel both testicles in the scrotum usually at four weeks of age.
