Why Do Piglets Huddle Together?

When piglets are cold, they may huddle together: this reduces the body surface exposed to cold air and helps conserve heat. Studies have observed this clustering during cold conditions, and physical contact also affects where piglets settle. “For safety,” however, is too definite an explanation: closeness may be social behavior, but the cited studies directly support thermoregulation more clearly than a protective motive. Piglets do not always sleep pressed together; behavior also depends on temperature and housing conditions. The illustration is AI-generated.
