What is the term for a pig that weighs less than 130 lbs?

The term "pig" is used to describe a young swine, particularly one that weighs less than 130 lbs. In the agricultural context, swine classifications differentiate based on age and weight; a pig is typically considered any young animal and often refers to those that haven't reached significant weight milestones. This terminology is important for understanding livestock management, breeding, and market classifications.

The other terms refer to specific types and classes of swine. A "hog" is generally a term used for larger, older pigs, often weighing over 130 lbs. A "barrow" is a castrated male pig, while a "boar" is a fully intact male pig. Therefore, the most accurate term for a pig weighing less than 130 lbs is simply "pig."
