pig, hog

Definition

A pig or hog is a type of four-legged, hoofed animal that is raised for meat. Its meat is referred to as pork.

God told the Israelites not to eat pig meat and to consider it unclean. Jews today still view pigs as unclean and do not eat pork.
Pigs and hogs are raised on farms to be sold to other people for their meat.
There is a kind of pig or hog that is not raised on farms but rather lives out in the wild; it is called a "wild boar." Boars have tusks and are considered to be very dangerous animals.
