Water cooling must be combined with strong ventilation to achieve the desired effect, otherwise it will cause high temperatures and high humidity, which is counterproductive.
- The spray cooling is applicable to the breeding gestation house, the growing house and the barn, and spraying water for 3 minutes to 5 minutes every 40 minutes.
- Cooling dripping is applicable to the limit bar and high slotted delivery room. It is best to use neck dripping to cool nursing sows. It is best to be automatically controlled. Drop every 15 minutes for 30 seconds to 1 minute. Dropping temperature can make nursing sows The feed intake increased by 20%.
- Flush shower cooling applies to fattening pig houses, breeding houses and boar testicles local cooling, shower 2 times a day, avoid spraying cold water suddenly pig head, boars within 1 hour after the end of the species with the prohibition of showering.

The open boar should be adopted in the south boar, pregnant sow house, and growing house.
- The roof of the pig house, the wall and the floor of the barn are made of materials with good thermal insulation properties, such as shavings or foam under the roof tiles, hollow bricks for the walls, insulated cement or slatted floor for the porch floor.
- Extend the width of the roof of the pig house to reduce the absorption of heat; Raise the shade of the sun screen on the roof of the pig house and on both sides of the direct sunlight to avoid direct sunlight.
4. Wet curtain cooling or air conditioning cooling:
conditional pig farm delivery room and nursery can use wet curtain cooling system, generally reduce the temperature 5 °C ~ 8 °C; breeding pig farms and the use of artificial insemination farms can be Installation of air conditioning.
