Which of the following describes a male pig?

A male pig is referred to as a boar. This term specifically identifies an intact male pig that is typically older and can be used for breeding purposes. Understanding the classification of pigs is important in livestock management, as it helps in determining the reproductive capabilities and the appropriate care for each type of pig.

The other terms used for pigs pertain to different classifications: a sow is a female pig that has given birth, a gilt is a young female pig that has not yet farrowed, and a barrow is a castrated male pig, which is typically raised for pork production due to the absence of testosterone-related behaviors and traits. This distinction helps farmers and breeders manage their herds effectively according to the roles different types of pigs play in production systems.
