Pigs, also known as swine, are domesticated mammals belonging to the family Suidae. They are characterized by their stout bodies, short legs, and a snout that is highly sensitive and used for foraging. Pigs are omnivores, meaning they eat both plants and animals, and they are known for their intelligence and social behavior. Pigs are raised worldwide for their meat, known as pork, which is a significant source of protein in many cultures. They are also used in various agricultural practices, such as truffle hunting, due to their keen sense of smell. Additionally, pigs play a role in scientific research because of their physiological similarities to humans.
