How to control the temperature and humidity of the duck house?

1. Temperature control of duck house by duck raising equipment
The temperature of ducklings: 35-33 ℃ for 1-2 days, 33-32 ℃ for 3-7 days. After that, the temperature of ducklings decreased by 21-18 ℃ for 5-6 weeks. Besides the thermometer, the behavior of ducklings should also be observed. For example, when the temperature is normal, the ducklings are lively in spirit, good appetite, moderate in drinking water, quiet in sleep, comfortable in sleeping posture, mostly lying on the bed, and the ducklings are evenly distributed in the whole nursery; when the temperature is high, the ducklings are far away from the heat source, their wings are extended, their necks are extended, their mouths are opened, and their appetite is not good; when the temperature is low, the ducklings are dense and close to the heat source as far as possible, crowded and clustered, shivering Shake, send out the "chirp" sound of afraid of cold, loss of appetite. Ducklings are sensitive to cold and warm, so special attention should be paid to prevent the temperature from rising and falling, and try to keep the temperature balance as much as possible. When mastering the temperature, the temperature should be higher at night or in rainy and snowy days; the temperature of ducklings should be lower when they are active in the daytime; the temperature of weak nestlings should be higher and the temperature of healthy nestlings should be lower.

2. Duck raising equipment to control humidity of duck house
Humidity is closely related to water evaporation, heat emission and sanitation of duck house.
① In high temperature and low humidity, the water loss in the duck body is too much, which is easy to cause dehydration of the ducklings. In addition, due to the dry and dust in the house, it is easy to induce respiratory diseases.
② When the temperature is high and humidity is low, the house is cold and humid. The duckling is easy to catch cold, which causes damp bedding, and gastrointestinal diseases and coccidiosis.
③ When the temperature is high and humidity is high, the heat in the body of the duckling is not easy to radiate normally, it is stuffy, the appetite is decreased, the growth is slow, and the resistance is weakened. Normally,
When the humidity of duck house is controlled by the equipment, it is better to keep dry, which can prevent bacteria from propagating and infecting, but the relative humidity should not be less than 40%. Suitable relative humidity: 60% - 65% before 10 days old, 50% - 60% after 10 days old. When the humidity is not enough, water can be sprinkled on the corridor, ground, surrounding walls or flue in the house, or water can be put on the heat source to evaporate water vapor, so as to increase the humidity in the house; when the humidity is too high, a moisture-proof layer can be laid on the ground of the duck house, the temperature in the duck house can be increased appropriately, ventilation and air exchange can be strengthened, bedding materials can be changed frequently in the flat duck house, and wet feces and bedding materials in the house can be removed in time to prevent leakage of the water dispenser Water and so on.
