Why do pigs like mud?
Pigs like mud because they can't cool themselves by sweating. The mud keeps the pig cool from the sun.
To thermoregulate, pigs rely on wallowing in water or mud to cool the body. While many have suggested that pigs wallow in mud because of a lack of sweat glands, pigs and other wallowing animals may have not evolved functional sweat glands because wallowing was a part of their behavioral repertoire.
