The sun radiation disease and heat radiation disease of pigs are caused by high temperature.
Pigs are prone to heatstroke in hot summer. In fact, heatstroke is the general name of solar radiation disease and heat radiation disease, and Chinese veterinarians call it black sweat wind. The causes of solar radiation disease and heat radiation disease are different, but their pathological processes can not be completely separated. Solar radiation disease is due to pigs exposed to direct sunlight for too long, resulting in an increase in physiological body temperature, skin overheating, warming, resulting in skin vascular dilatation.
