Pigs wallow in mud to keep themselves cool in the summer because they don't have sweat glands. This summer, watch for signs of heat stress in your pigs, such as increased panting, additional water intake and loss of appetite.
Consequently, how do pigs regulate their body temperature?
Ways that pigs control their heat loss is by regulating their blood flow, huddling together in groups or burrowing into the bedding. Temperature control is important for production. Above all, pigs cannot thrive outside of the TNZ. A pig's inability to maintain its body temperature could result in its death.
Furthermore, how hot is too hot for a pig?
Heavy pigs most vulnerable Heavier pigs produce more body heat and are most susceptible to heat stress. The real danger is when the temperature is greater than 30 °C (86°F). If the deep body temperature of the pig reaches 43°C (109.4°F), it dies - from heart failure.
Remember, Pigs don't sweat and can easily overheat very quickly. Please read the following section to determine what symptoms to watch for that can indicate your pig may be overheated. Without sweat glands, pigs cool down by laying on the cool ground, laying in mud holes or taking a dip in a kiddie pool.
