According to knowledgeable people, it is most accurate to touch the tip of the ear, the tip of the tail, the nose and the four hooves (at the hoof fork) when a pig has a fever. When a pig has a fever, the temperature of the tip of the ear, the tip of the tail, the nose and the four hooves (at the fork of the hoof) are hot, but the ears and tail are cold, and the pig nose mirror (at the upper mouth) is dry and even chapped, so I like to lie down.
