Cold winter weather, laying hen farmers should pay attention to the cold and warmth of the chicken house, to avoid cold stress to the farmers to bring unnecessary losses, especially semi-open chicken house should pay attention to take measures.
Understand and skillfully use the ventilation mode of the sheds for horizontal negative pressure ventilation. Because the fan is installed on the side walls and gables in different positions, the static pressure in the shed, the size of the air inlet, the wind speed, and the direction of the wind are all different. Discrimination.
Prevent cold wind from hitting cold air inside the chicken house may come from cracks in doors, windows, etc. The local wind speed can sometimes reach 5-6 meters per second. It must be blocked tightly. Sometimes the cold wind comes from the manure outlet of the dung ditch. Install the flaps to keep cool.
Set up a wind barrier outside the house Open-style chicken house is best to set up a wind barrier in the northwest to prevent the northwest wind hit the chickens, the chicken house can be sealed north window, to the sheds hanging cotton door and so on.
Pay attention to the ventilation In extremely cold conditions, the small inlet window can be opened one at a time, and the opening is controlled at the lowest level. Appropriate array of gusts during the excrement, each 10-15 minutes. Since the optimum temperature for laying hens is 18-25°C, if the temperature drops below 13°C, the egg production rate will begin to decline, and the duration of hypothermia will be too long, which will also cause upper respiratory tract diseases. Therefore, the open chicken house can open the sunny window after 9am, illuminate the sun, regulate the temperature, and look at the weather in the afternoon to close the doors and windows promptly. In winter, the chicken house is mainly insulated and supplemented with ventilation. During the day, intermittent ventilation can be used according to the air quality in the house. If conditions permit, the temperature controller can be installed in the house, and the opening and closing of the fan and the small window can be adjusted according to the set target temperature, which can effectively solve the contradiction between ventilation and heat preservation.
