1. Cover the roof or windows of small and medium-sized pig farms with black shading protective nets to reduce direct sunlight or long-term ultraviolet radiation to achieve the purpose of cooling.
2. Open the doors and windows of the enclosure to maintain air circulation, and increase cooling and exhaust equipment, such as electric fans, exhaust fans, air conditioners, etc.
3. Add water curtain facilities at the door and window of the pig house, so that the cold water can flow freely or form a spray-like cooling effect faster and better.
4. Reduce the density of pigs to achieve the purpose of heatstroke prevention and cooling.
