How to prevent heatstroke and cool down the chicken house in summer How to cool down the chicken house in summer
1. When the temperature in the chicken house is 1-4 degrees Celsius higher than the set temperature, consider strengthening ventilation and using the air cooling effect to cool down; when the temperature in the chicken house is more than 5 degrees Celsius higher than the set temperature, consider using Wet curtain cooling.
2. Everyone should first understand one issue: opening the wet curtain is not only for cooling, but also to control the temperature in the chicken house within a relatively reasonable temperature range.
Under normal circumstances, after the wet curtain is opened, the temperature is maintained within a range of 1 degree Celsius. For example, the temperature when the wet curtain is opened today is 30 degrees Celsius. After the wet curtain is opened, the temperature can be maintained at 29-30 degrees Celsius. The temperature must not be lowered too much at once. In a short period of time, if the temperature difference exceeds 5 degrees Celsius, the chickens may catch a cold.
3. Open the wet curtain, ranging from small to large, first use the two side walls, and finally use the gable wet curtain, and finally install a windshield curtain in the chicken house to reduce the cross-sectional area of the chicken house and increase the wind speed. .
4. Under normal climate, the temperature when opening the wet curtain should be lowered by 0.3-0.5 degrees Celsius every day. When the temperature when the wet curtain is opened drops to 26 degrees Celsius, there is no need to lower it further.
5. After opening the wet curtain, be sure to avoid cold wind blowing directly on the chickens.
For farms with wet curtain panels, the slope of the wet curtain panels can be used to guide the wind direction; for farms without wet curtain panels, plastic paper or bags can be used to guide the wind direction.
6. After opening the wet curtain, pay attention to the temperature difference between the two ends of the chicken house to be controlled within 2 degrees Celsius. Reasonable use of the number of fans to control the temperature difference. If four fans can control the temperature difference well, don't turn on five; if five fans can control the temperature difference well, don't turn on six to minimize the impact of the air cooling effect on the chickens.
7. After turning on the wet curtain, you must grasp the time of opening and closing the wet curtain.
After turning on the wet curtain, be sure to grasp the time of the wet curtain switch. It can be turned on for 3 seconds and not turned on for 5 seconds, and it can be stopped for 10 minutes and not stopped for 8 minutes.
The water curtain opens intermittently: The time when the water curtain water pump is turned off is more important than the time when it is turned on. Wait until the water curtain paper is completely dry before starting the water pump to supply water. The water curtain must always be in a cycle of gradually drying and getting wet. in order to achieve the best effect of water vapor evaporating from the surface of the water curtain paper.
8. If the chickens are younger than 25 days old, mixed ventilation can be used (wind windows, doors and wet curtains are opened at the same time); for older chickens, the wet curtains can be opened Finally, check whether the small air inlet window is closed tightly to prevent local chickens from being overheated due to lax closing of the small window.
9. After opening the wet curtain, check whether there are any ventilation dead spots in the chicken house. If so, the chickens there should be driven out.
10. When opening the wet curtain, pay attention to the external humidity.
When the outside humidity is lower than 50%, try to avoid opening the wet curtain, because opening the wet curtain will cause a great cooling effect; when the outside humidity exceeds 80%, it is what we call sauna weather. This At this time, the cooling effect of the wet curtain is not obvious. At this time, you must turn on as many fans as possible to use the air cooling effect to cool down.
