What is a male bovine referred to as?

A male bovine is referred to as a bull. Bulls are specifically intact male cattle that are capable of breeding. This distinction is important in cattle management and breeding practices, as bulls are generally used for their reproductive capabilities. They are typically kept for breeding with females to produce calves.

Understanding the characteristics of each term helps clarify why 'bull' is the correct answer. A steer is a castrated male bovine typically raised for beef production. A calf is a young bovine of either sex, usually under a year old. A heifer refers to a young female bovine that has not yet given birth. Therefore, the term 'bull' is specific to intact males that can perform the role of a sire in herds, distinguishing them from other classifications of bovines.
