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

The term for a female swine that has not yet given birth is "gilt." This terminology is used in the swine industry to specifically differentiate between female pigs based on their reproductive status. A gilt is a young female, usually younger than a year, that has not yet produced piglets.

In contrast, once a female swine has given birth, she is referred to as a "sow." A "boar" is a male pig, while a "filly" pertains to young female horses, further highlighting the importance of context and specificity in agricultural terminology. Understanding these definitions is crucial for effective communication within the industry, whether in breeding, farming practices, or livestock management.
