The cold winter weather has caused many inconveniences to the production of chickens. In particular, the effect of low temperatures on laying hens is very obvious. Wang Jingyu, a professor of animal medicine at Northwest Agriculture and Forestry University, introduced that winter chickens should pay attention to the following aspects to ensure that winter cold does not affect aquaculture efficiency.

Warm and cold
In winter, the temperature is low, and appropriate measures can be taken to increase breeding density, close doors and windows, add straw curtains, drink warm water and stove heating, etc., so as to maintain the temperature of the chicken house at a minimum of 3°C-5°C.
Scientific ventilation
In winter, the temperature is relatively low, and the farmers often close the doors and windows of the chicken house with strict ventilation. The harmful gases such as ammonia gas, carbon dioxide, and hydrogen sulfide produced by chicken exhaust gas and chicken manure fermentation cannot be distributed in time. Therefore, it is necessary to effectively handle the relationship between ventilation and warmth, and timely remove the feces and debris in the chicken house. When the weather is good at noon, the windows should be ventilated so that the air in the house is fresh, the oxygen is sufficient, and the humidity is reduced. In the winter season, the house has a small amount of ventilation, and the evaporation of water is reduced. In addition, the hot air in the house is exposed to the cold roof and the wall will condense into a large amount of water droplets, causing excessive humidity in the house and creating a large number of bacteria and parasites. condition. Therefore, we must strengthen management, pay attention to keep the house clean and dry, timely repair of damaged sinks, avoid overfilling with too much water.
Artificial light
In winter, due to the short night, the lack of light in laying hens caused the egg production rate to decline. In order to overcome this natural defect, artificial supplemental lighting can be used to make up for it. In general, the total daily light time should not be less than 14 hours or 17 hours. For example, the natural daytime light is 12 hours, and it takes 2-5 hours to manually supplement the light every day.
Timely disinfection
Disinfection work should be carried out throughout the entire process of raising chickens. The temperature in winter is low, and the frequency of bacteria activity decreases. However, the winter weather is cold and the chicken's resistance is generally weakened. Disregarding disinfection can easily lead to outbreaks of disease.
Increase energy feed
Chicken feed on the body to obtain heat to maintain body temperature. The lower the temperature of the outside world, the more the chicken consumes the heat of the cold. It has been determined that winter chickens consume 10% more food than other seasons. Therefore, in the winter chicken feed must ensure sufficient energy, in addition to ensuring a certain percentage of protein, should be appropriately increased high-energy feed containing starch and sugar, in order to meet the chicken's physiology and production needs. Appropriately increase the content of vitamins and trace elements in feed. The resistance of chickens in winter has declined. Special attention should be paid to regular vaccination.
