A young female hog is called a "gilt." Gilts are typically female pigs that have not yet given birth. Once they have had their first litter, they are referred to as sows.

No. A sow is a female pig or hog (or even a bear, raccoon, etc.), not a domestic bovine.

A young male hog is called a Shoat, and a female is called a Gilt. As a group they are known as piglets.
