Chicken house environment winter control
temperature
It is advisable to keep the temperature at 18~23°C and the minimum temperature should not be less than 15°C. In case of windy weather, the tarpaulin should be shaken (according to changes in the outside temperature, half or all of it should be shaken) to prevent the temperature inside the home from suddenly falling. Every day, the size of the air inlet is adjusted according to the weather conditions and the performance of the flock. The air inlet should be fixed with iron wire or rope firmly to the plastic cloth and plywood, so that the wind blowing upward, do not let the cold wind directly blow chickens, to prevent cold stress caused chicken disease. The exhaust fan cannot be opened and it is easy to cause air pollution in the house. When installing the timed temperature control exhaust fan, select the louvers to be complete. Do not select the north-facing exhaust fan.
Before the winter, clean up the dust from the heater, and make the louver parallel when the heater is first opened, so that the hot air can fill the shed evenly.
ventilation
In the winter season, it is better to use fresh air and slower air flow. Before winter, repair the area that should not enter the wind, especially the exhaust air at the exhaust fan must be handled well to prevent the chickens from being affected due to the partial cold air, the poor ventilation of the house and the low temperature near the exhaust fan. And it affects production. When the smell of ammonia in the house is large, the temperature in the house should be increased first, and then the ventilation volume should be increased. When the air in the house is relatively dirty in the morning, if it is necessary to increase the amount of ventilation, it should be gradually increased, preferably at a high temperature at noon. Each ventilation time can be shorter and ventilation times can be more. Never leave dead corners when ventilating. If you want to increase the number of fans to open, carefully observe the performance of the flock after the increase, and proceed without any adverse reactions.
humidity
Add litter before winter. Winter litter is relatively dry, and it is often sprayed or spray-disinfected. If there is water under the scaffolding, the water under the scaffolding will be released in the autumn when the temperature is high, and then sprinkled with white ash. When the room temperature is appropriate, increase the ventilation. If the water leakage from the drinking fountains is to be dealt with in time, prevent the ammonia smell in the chicken house from being excessive due to water leakage.
