Do pigs sweat? | Live Science

The phrase “sweating like a pig” can conjure up mental images of streams of sweat pouring down pigskin on a sweltering day, but it’s one of the most misleading idioms in the English language. Pigs have only a limited number of functioning sweat glands, so they sweat very little, and the small amount of sweat they produce doesn’t have much of an impact on their body temperature. So, how pigs cooling down?

Pigs are endothermic, or warm-blooded, meaning they maintain a stable body temperature regardless of the temperature of their environment. In most cases, the body temperature of endothermic animals is warmer than that of their environment. Conversely, ectotherms, or cold-blooded animals, depend primarily on external heat sources, so their body temperature changes along with the temperature of their surroundings.
