In the process of raising chickens, many farmers are not aware of the importance of ventilation, and it is considered that feeding and temperature and humidity management are more important. However, if the chicken house does not reach reasonable ventilation, some harmful gases in the house will not be discharged, and fresh air will not enter, which will cause some diseases in the flock. Fans are common chicken ventilation equipment used by farmers. If the farmers use them improperly, the effect will be unsatisfactory. So the following author will talk about the details of using the fan of the poultry farming equipment.

1. Use fan equipment for ventilation, farmers must pay attention to the tightness of the house, the better the house is sealed, the better the ventilation effect. However, to leave a few small windows, the minimum opening distance of the fan ventilation window is: 2.5-75px.

2. When the farmer purchases the fan equipment, the number of required fans should be calculated according to the area of the house. Pay attention to the size and quantity of the house to avoid excessive negative pressure, resulting in lack of oxygen in the house.

3. If the farmer adopts longitudinal ventilation, it should be noted that when the wind speed is very low, it is necessary to check whether there is any air leakage. Is the belt of the fan loose, the curtain is dirty or clogged, and the number of fans is appropriate.

4. For the number of opening of small windows, the farmers should determine according to the temperature inside the house and the number of fans. If it is more than two, when the side fan is running for a long time, it is necessary to consider all the small windows. If it is lower than two fans, you should consider closing half of the small window.

5. Many farmers have a common misunderstanding. The higher the wind speed, the better the ventilation effect will be. In fact, the higher the wind speed, the better. Generally, the longitudinal ventilation speed in summer is no more than 2.5 m/s. Scientific research has shown that the wind-cooling effect is no longer enhanced even if the wind speed exceeds 3 meters and the wind speed is increased.

6. Farmers should also pay attention to the fact that chicks are more aware of the wind speed when ventilating the chicks. Therefore, farmers should remember that at the same temperature and wind speed, chicks have twice the somatosensory temperature than adult chickens.

The above six points are some details of the attention of the farmers in the process of using the fan equipment for breeding laying hen poultry equipment. I hope that the above description can help the farmers. In addition, farmers should pay attention to the fact that the fan equipment should be regularly maintained and maintained, which can extend and maintain the service life and efficiency of the equipment.
