A young female pig is called a?

A young female pig is correctly referred to as a gilt. This term specifically denotes a female pig that has not yet given birth (farrowed). In the livestock industry, differentiating between various stages of development and reproductive status is essential, and terminology helps convey these important distinctions.

The term gilt is widely used in breeding and farming contexts to identify young females, marking a crucial stage in their growth before they reach maturity and become sows, which are females that have already given birth. This vocabulary is significant for farmers and breeders in managing their herds and understanding animal husbandry practices.

The other terms do not correspond to female pigs. A boar is a mature male pig, a wether is a castrated male sheep, and a sow is an adult female pig that has farrowed, which is a different life stage altogether. Therefore, the use of gilt specifically addresses the young female aspect of swine terminology, making it the appropriate answer.
