How to manage the chicken house environment of broilers in winter

In the environmental management of  broiler houses in winter, firstly ensure the normal operation of heating equipment and take early warning measures for emergencies, which is the basic work of winter management. Secondly, the environmental regulation of the chicken house must be based on the feelings of the chickens. The technician must enter the chicken house to observe the state of the chickens and make adjustments to the environmental equipment. loss. This is also not recommended.

So where should we start?

1. Know the local weather forecast for the next 24 hours or a week in advance, make a small plan for the work, and take preventive measures to avoid being caught off guard. The plan should fully take into account the human factor. It is unreasonable to control the plan beyond the scope of human control, and it will only be counterproductive to do what cannot be done. Absolutely ideal environmental conditions (the content of authoritative materials such as textbooks and feeding management manuals) are difficult to achieve, but they must be used as the direction and purpose of regulation.

2. In winter, environmental factors such as temperature, humidity, temperature difference (day and night temperature difference and local temperature difference in the house), air quality and other environmental factors will present various contradictions due to changes in the external environment, such as strong winds or sudden changes in weather. The difficulty and breakthrough of environmental regulation lies in the balance between these major elements. The basis for the balance is the actual feeling of the chickens. The key to the balance lies in ventilation. The setting of relevant parameters of environmental control equipment is an important means to adjust the balance. The opening and use of tubes and small windows is the most important key point and the most important control device. It is important to know that it is almost impossible to achieve a completely ideal state, the key is to balance a variety of factors to make the bird feel comfortable and avoid stress.

3. The transition between de-warming and warming-up is the most difficult detail to grasp. Premature de-warming chickens are more likely to catch cold. By observing the molting speed of the chickens, the dewarming time is determined according to the actual situation of the chickens.

Fourth, chicken house dust is also one of the most important environmental factors. Once the dust exceeds a certain range, airsacculitis and bronchial embolism will follow, because we provide the most convenient means of transportation for bacteria and viruses. The larger the house, the more difficult it is to control dust, as dust particles enter the lungs with breathing, and pathogenic bacteria then reach air sacs throughout the body. When the body’s resistance drops to a certain level, various diseases will break out. At this time, any drug can not achieve the desired therapeutic effect. Therefore, in winter we should focus on dust concentration to avoid the spread of respiratory diseases.
