What is the term for a female pig that has not yet given birth?

The term for a female pig that has not yet given birth is "gilt." This designation is important in agriculture and animal husbandry as it differentiates between female pigs based on their reproductive status. A gilt is typically young and still developing, while a "sow" refers to a female pig that has already farrowed, or given birth.

Understanding these terms helps in managing breeding programs and livestock classifications effectively. In contrast, a "boar" is a male pig capable of breeding, and a "barrow" is a castrated male pig, neither of which pertains to the reproductive status of a female pig. Knowing these distinctions is crucial for anyone involved in pig farming or swine production, as it influences breeding decisions and herd management.
