How to increase the temperature in the chicken house in winter

First, install the thermostat

Use the thermostat to control the temperature and ventilation of the house to achieve minimum ventilation management. Usually, the minimum ventilation for broilers on the web is 0.0017 cubic meters per minute. This will not only allow the temperature of the house to meet the normal growth and development of the chicken, but also saves coal, and also reduces the cold wind on the chicken body. Stress.

Second, install the air duct

Install an air duct with a diameter of 16 to 18 centimeters and a length of 35 to 4 meters every 4 meters along the vertical wall on both sides of the coop, and install it along the ceiling. Use plastics, polyvinyl chloride (PVC), fiberglass, and other lightweight materials. The material can help to control the minimum ventilation while avoiding cold air blowing directly to the chicken and reducing the chicken's stress response. This will not only maintain the indoor temperature, but also ensure the quality of air and reduce the occurrence of respiratory diseases. If you take this measure and close the air intake, you can save energy and improve the feeding efficiency.

Third, heating stove heater

Among all the heating methods, the heat efficiency of the heating furnace is the highest, and the temperature rise is fast, which can meet the needs of chicken house temperature to the maximum extent, which will help save the cost. Because the temperature difference between exhaust gas and supplemental fresh air in the winter house can reach 30-45°C, there is also a difference in humidity between the exhaust gas and the fresh air, and waste heat (including sensible heat and a small amount of latent heat) has certain utility value. Therefore, in order to solve the contradiction between ventilation and ventilation, it is possible to use the waste heat heater in the exhaust gas to reduce the energy waste and improve the breeding efficiency.

Fourth, promotion of hanging smoke

If furnace heating is used, the circulation length of the chimney should be extended as much as possible so that the heat generated by coal combustion can be distributed in the chicken house as much as possible to reduce the waste of heat energy. The smoke outlet should not touch the heat, and the length of the chimney is generally. About 20 meters.

Fifth, build a greenhouse

At present, some farmers use the method of constructing plastic film insulation sheds on the front and rear sides of the chicken house to use solar energy. This not only absorbs the heat of the sun, but also reduces the heat loss of the chicken house, and it can save about one-third of energy. Avoid cold wind directly into the coops causing cold stress, this new measure has been recognized by the majority of farmers.
