Solutions for heatstroke prevention and cooling in pig farms What are the solutions for heatstroke prevention and cooling in pig farms?

1. Strengthen ventilation: always remove weeds around the pigsty, open all doors, windows and vents for ventilation as much as possible, and use electric fans and exhaust fans to strengthen air flow in the pigsty.

2, water cooling: water cooling must be combined with strong ventilation to play its due role, otherwise it will cause high temperature and high humidity, which is counterproductive.

(1) Spray cooling is suitable for breeding houses, growing and fattening houses, and male pig houses. Spray water every 40 minutes for 3-5 minutes.

(2) Drip cooling is suitable for limit fences and high delivery rooms that leak rain, and drip cooling is used for lactating sows, so that it can be controlled automatically. Drip cooling every 1 min for 30 seconds to 1 min can increase the feed intake of lactating sows by 20%.

(3) Washing and shower cooling is suitable for local cooling of fattening pig houses, breeding pig pregnancy houses and boar testicles. Take a bath twice a day, and it is forbidden to suddenly spray cold water on the pig's head. It is forbidden to bathe boars within 1 hour after breeding.

(4) Water bath cooling can build a pool on the sports ground, so that boars and weaned sows can bathe freely to cool down.

(5) In addition, there is also water spraying on the roof or artificial water spraying to cool down.

3. Change the structure of pig house or install sunshade curtain to cool down: The male pig house, pregnant sow house and growing and fattening house in the south should adopt open structure.

(1) The roof, wall and ground of pigsty should be made of materials with good thermal insulation performance, such as wood shavings or foam under roof tiles, hollow bricks for walls, and thermal insulation cement or rain leakage ground for pigsty ground.

(2) Expanding the width of the pigsty roof can reduce the heat absorption; Pull a sunshade net on the roof of the pigsty and on both sides of the direct sunlight to avoid direct sunlight.

4. Wet curtain cooling or air conditioning cooling: Wet curtain cooling system can be used in the delivery room and nursery room of pig farms where conditions permit, which can generally reduce the shed temperature by 5℃ ~ 8℃; Breeding pig farms and artificial insemination male pig houses can be equipped with air conditioning.
