How to keep chickens warm in winter? Management of chickens in winter

For the breeding industry, warming in winter is very important, and the same is true for the chicken industry. However, if the environment is too closed, harmful gases may exceed the standard and damage the health of the chicken, then what measures should be taken in winter? Does the chicken stay warm without affecting its health? Here is an introduction for everyone.

1.Enhance the ventilation of the chicken house in winter
  Modern chicken farms must do a good job of preventing cold and heat in order to bring the most suitable environment to the chicken flocks and exert their best productivity. Strengthening the ventilation of the chicken house in winter can make the temperature in the house even, and prevent the harmful gas from exceeding the standard. Studies have shown that ideal ventilation conditions should be uniform air supply through ducts, air intake by skylights or hoods, and pre-heating the cold air outside the chicken house in the form of airflow and evenly distributed to the inside of the chicken house. It has a good effect on raising the average temperature in the house, improving the humidity and carbon dioxide distribution in the house, avoiding cold stress, and increasing the egg production rate of the flock. The temperature of the chicken house in winter cannot be less than 8 ℃, otherwise the egg production rate of the hen will be greatly affected.
  At present, most chicken farms do not know enough to control the ventilation volume in winter chicken houses. The lack of understanding of the concept of actual exhaust volume has resulted in a large difference between the ventilation volume and the required ventilation volume in the henhouse, resulting in heat loss. At the same time increased energy consumption. Therefore, in order to meet the ventilation requirements, the wind speed in the chicken house should be ≤0.3 m · s-1.
  2. Appropriately increase the light in the hen house
  In the cold-proof and heat-preservation work of the chicken house in winter, the light management of the house is particularly important. Properly increasing the light of the house can not only effectively kill some germs, maintain the sanitation of the house, but also increase the temperature of the house, such as in sunny At noon in winter, the roof of the chicken house can be opened to direct sunlight, which can not only improve the laying rate of laying hens, but also increase the growth rate of chickens, and bring considerable economic benefits to the farm.
  3. Properly increase the feeding density of the chicken house
  It is generally believed that properly increasing the feeding density of the henhouse can increase the temperature of the henhouse, which is conducive to the cold-proofing and thermal insulation work of the henhouse in winter, but the feeding density should not be too high. The experiments show that when the feeding density of each cage is less than 4.2, it can maintain the high productivity of laying hens, and at the same time, it has a positive impact on the cold protection and insulation work of the chicken house. Therefore, in the winter, the feeding density of the chicken house can be appropriately increased to increase the temperature of the chicken house, which brings considerable economic benefits to farmers and reduces energy consumption.
  4.Add insulation equipment
  The temperature-increasing technology of chicken coops in winter is mainly fire heating, plumbing or electric heating. Generally, heating equipment needs to be configured according to the geographical environment and climate of the breeding site. For example, in the north, winter is usually dry and lasts a long time. With wind heating effect is better. Plumbing mainly uses the characteristics of large specific heat capacity of water. The water distributed in the warm aluminum flakes in different positions of the chicken house is heated by a boiler, and heat is transferred to the chicken house through heat conduction to increase the temperature in the chicken house. This method uses energy. High, cost-saving and widely used. The temperature in winter is relatively high in the south, so it is suitable to use energy-saving hot-air stove. The hot-air stove is mainly used to blow warm air directly into the chicken house to increase the temperature. Experimental research shows that the use of a hot air stove can effectively increase the temperature in the chicken house, combined with the regular ventilation function can also significantly improve the air quality in the house, which is welcomed by the majority of farmers. In some European countries, plastic storage tanks are usually used, and at the same time, heat insulation design is used to maintain the temperature in the chicken house in winter.
  5.Improve the enclosure structure of the chicken coop
  According to the climatic data of each region, and according to the calculation method of general building thermal engineering, it was found that when the temperature of the chicken house is 10 ° C, the production capacity of the laying hens is maintained at an optimal level, and the temperature of the chicken house is best maintained at this level in winter . Since the heat loss is directly proportional to the heat loss area, it is required that when determining the area of ​​the chicken house, comprehensive consideration should be given to the breeding scale and the use of machinery and equipment to minimize the outer protective area.
  After the enclosure structure of the henhouse is determined, the heat balance of the henhouse must be considered. When the total heat output of the henhouse is balanced with or loses heat, the temperature of the henhouse must be ≥10 ℃. The main sources of heat generation in the chicken house are the free heat emitted by the chicken body, the radiant heat emitted by the sun through the doors and windows, the heat generated by the lighting lamps, and the heat generated by mechanical operation. Heat dissipation from the ground, etc. Therefore, the construction of the chicken enclosure should be reasonably improved during the construction of the chicken coop, and as far as possible, some materials with large thermal resistance and good thermal insulation performance should be used to reduce heat loss and increase the temperature of the chicken coop. In addition to considering the creation of a good environment in the hen house, it should also pay attention to the plant environment and provide an ideal microclimate. Strengthen the cold-proof and thermal insulation performance of the hen house in all aspects to better ensure that the laying hens in winter have good production. Egg rate.

  The above are the suitable means to keep the chicken house warm in winter. Do you remember? No matter what season it is, the ventilation of the chicken house is very necessary. Don't give up the ventilation to keep warm. If it causes disease, it will cause greater losses.
