As the weather becomes colder and colder, how to make the environmental conditions in the chicken house relatively stable in the cold season so as to ensure the normal growth of the chicken is a matter of concern to laying hen farmers. Many farmers think of how to keep the chicken house warm and ignore the importance of ventilation. In fact, chickens are very sensitive to changes in the environment, the weather is very cold, the temperature is too low, ventilation is poor, and the concentration of poisonous and harmful gases is too high. This can affect the production of eggs and meat and affect the health of the flock. It even induces various diseases. Therefore, it is very important to do a good job in the environmental regulation of chicken houses. It is better to use vertical negative pressure ventilation in the house, that is, there are air inlets on both sides of the front of the house (with a black cover device). The size of the air inlet can be adjusted with the change of climate and installed at the rear of the house. Mechanical exhaust equipment. The control of the environment is different depending on the stage of chicken development. The brooding hen houses must be fully enclosed to prevent the flow of workers and utensils in poultry houses from crossing each other. There must be heating equipment inside the house and all air inlets should be closed tightly to prevent intrusion of thieves. Before the chicken enters the market, the temperature of the house is raised to about 33°C, and the temperature under the umbrella is 35°C~36°C. The breeder should carefully observe the behavior of the chicken, understand the cold and hot performance of the chicken, and conduct short-term ventilation (up to 2 minutes at a time) according to need. The cold air cannot be directly blown to the chicken body. Later, as the age of the chicken increases, the shepherd temperature should decrease steadily (about 3°C ​​per week). After the chick's fluffy feathers are replaced by young feathers, the temperature can be reduced to about 18°C. The temperature requirement of breeding chickens is not very high. As long as the chicken has a reasonable weight gain, the temperature can be maintained at 13°C~15°C, and the lowest temperature is not lower than 10°C, otherwise it may cause the breeding chicken to delay production. Egg laying hens have very strict temperature requirements. Generally speaking, the shepherding temperature is not lower than 15°C. However, if the ventilation is poor, the air is contaminated, such as ammonia, carbon dioxide, hydrogen sulfide and other concentrations are too high (people feel pungent, tears). It will stimulate the chicken's respiratory system and endanger the health of the flock. Therefore, it is equally important for chickens to maintain heat and ventilation at this time. Our experience is to close some of the air intakes after the weather turns cold. If you use a wet curtain that cannot adjust the size of the air inlet (for summer use), cover the outside of the house with a draper (a woven bag of 2 or 3 layers can also be used), leaving only a small amount of air inlet at the top of the wet curtain; An air deflector is installed on the side of the sheli curtain (obstructed with a wood or cloth curtain) so that the cold air enters the upper layer of the chicken house to reduce the stimulation of the cold air to the chicken body. In addition, the ventilation system is preferably controlled by a temperature controller to set a lower limit temperature (for example, 15°C). Above this temperature, the fan is turned on automatically; otherwise, the fan is turned off. This method is both simple and economical and practical. It completely eliminates the delays caused by human factors. In short, winter is a season of high incidence of various viral diseases. As a manager, after winter, it is necessary to diligently observe the flock, pay attention to the pros and cons of environmental conditions in the house, find problems in a timely manner, and try to achieve environmental conditions in the homes. Smooth transition to avoid stress on the flock as it quenches.
