Matters needing attention in ventilation of chicken house

Chicken breeding is a relatively important breeding industry in China, which has a wide range of breeding area. It is indispensable to do a good job in basic management when raising chickens, especially disinfection and ventilation. The ventilation of the chicken house can effectively change the air and avoid the poor air quality affecting the growth of chickens. But there are a lot of things we should pay attention to when we are ventilated. The following editor brings you some precautions when ventilating the chicken coop. Let's take a look!

1. Keep airtight

When ventilating the chicken house, we should first ensure the airtight ability of the chicken house, and let the air carry on the chicken house from the vent of the chicken house, so as to prevent the leakage from affecting the growth of the chicken. We can test the closeness of the henhouse and turn off all the vents in the henhouse and keep a fan. Then observe the data changes of the special testing equipment, the lower the static pressure in the chicken house, the worse the tightness in the chicken house. For this kind of chicken coop, we should check the air leakage in time to make up for it, so as to prevent the chicken from catching a cold and affecting its growth in winter and other low-temperature weather.

2. Demand matching

In the chicken house ventilation should pay attention to observe the number of chickens in the chicken house, the ventilation should be kept in line with the number of chickens, to avoid too much or too little ventilation, will affect the growth of chickens. Some qualified farmers can install exhaust fans and other equipment in the chicken house. Improve the wind speed during ventilation, promote the discharge of poor air and heat in the chicken house, and improve the effect of ventilation. Pay attention to the weather when ventilation, if low temperature and rainy, then we should pay attention to ventilation, reasonable opening of vents, avoid improper ventilation, but also affect the growth of chickens.

3. Suitable temperature

If we want to know whether ventilation is effective and whether chickens can grow normally, we cannot just observe the degree of the temperature apparatus. It should be determined according to the chicken's body temperature and growth, such as observing the chicken's eating, drinking water, activities and feces to judge whether the chicken is comfortable or not. We have to observe the growth of the flock regularly, because the temperature of the chicken is different from that of the thermometer, so it is necessary to record the temperature change of the henhouse, the air velocity and the age and sex of the flock. Then, according to the statistics, the ventilation volume should be reasonably controlled to avoid excessive ventilation leading to temperature discomfort and affecting the growth of chickens.

4. Ventilation equipment

Ventilation mainly depends on fans, vents and other equipment, we should pay attention to the size of the fan when opening the vents. Ensure comprehensive and uniform ventilation, stabilize the static pressure in the chicken house, and control the air flow rate. The number of vents is mainly determined by the air velocity in the chicken coop. To ensure that the ventilation is symmetrical, install the deflector, and ensure that the air on the top of the chicken house is fresh enough. Fully mix with the lower air to improve the air quality in the chicken house and prevent the chickens from being blown directly by the cold wind.

The above is a brief introduction of the matters needing attention in the ventilation of the chicken coop. The ventilation of the chicken house is not just to open the vents. We should grasp the specific ventilation volume and time according to the weather and the age of the chicken. Do not be blindly ventilated, otherwise it will also affect the growth of chickens, leading to counterproductive. That's all for today's introduction. This article is for reference only.
