Cold insulation is an important part of laying hens. The most suitable temperature for laying hens is 13°C~20°C, and the temperature in winter is low and the cold current is frequent. Therefore, we must pay attention to cold and warm work, the need to use insulation material to close the doors and windows of chicken coops, or hanging in the outside of the doors and windows hanging cotton curtain, etc., and increase the housing density of the chicken house, try not to leave empty cages, use body heat to increase the temperature; Heating equipment such as coal stoves, hot air stoves, etc., thick mats of dry materials, hay, timely removal of accumulated manure, and frequent diligent littering.
Ventilation ventilation is an important measure to ensure the health of chickens and improve the performance of laying eggs. Winter chickens often pay attention only to the cold and warmth of the chicken house and neglect the ventilation and ventilation, resulting in an increase of harmful gas in the chicken house. Especially when the concentrations of ammonia and hydrogen sulfide increase, the chickens are susceptible to respiratory infections. Therefore, it is necessary to promptly remove the excrement in the henhouse, and to pay attention to the discharge of pollutants and humidity during the preservation of the house. In the winter, vents can be provided with a wind deflector, which is usually located above the house. The windshield is used to allow the incoming cold air to be blown upwards, mixed with warm air in the house, and then blown onto the chicken.
Moisture-proof and dehumidification Under normal conditions, the relative humidity in the house should be maintained at 60% to 70%. Humidity over the General Assembly to create conditions for the proliferation of bacteria and parasites, while also increasing the heat, can not reach the effect of chicken house insulation. Therefore, we must pay attention to keep the house clean and dry, as long as it can maintain a more appropriate temperature can increase ventilation to dehumidify. If ventilation is difficult to solve, powdered quicklime can be sprinkled around the house. This will serve two purposes, both moisture and disinfection.
