The tongue of the pig functions as an aid in simple tasks, such as suckling and eating. The tongue also contains taste buds that support the animal's sense of taste.
For a newborn pig, the tongue is critical for survival, as it helps create pressure in the mouth so the piglet can suckle properly. Pigs of all ages utilize their tongues for moving food in their mouths to aid in chewing and swallowing. Taste buds are found on the tongue, and pigs have more taste buds than humans. Studies of food palatability have shown pigs prefer certain foods, just like humans.
