To ensure the tightness of the house

The premise of effective ventilation is that the house must be kept airtight, allowing fresh air to enter the house from the side wall vents or the curtain at the front of the house. Therefore, it is required to inspect and test the tightness of each chicken house in the farm area. The internal pressure in the AC2000 system can be used for testing. All the air inlets in the house should be closed. Only one fan should be turned on to check the static pressure in the house. Standard comparison, the internal static pressure within the standard range indicates that the house is well closed, and the lower the static pressure in the house, the worse the tightness of the house.

For houses with poor airtightness, places where the air leakage is severe should be located, especially in front and rear doors, dung boards, and curtains. In addition, vertical ventilation systems are mainly used in high temperature periods, and wet curtain cooling systems are used.

Secondly, ensure the matching of demand and ventilation in the chicken house

Conditional chicken farms can install exhaust fans (fans), using negative pressure ventilation, increase the wind speed inside the house, increase the average airflow speed within the house, speed up the discharge of heat within the house, and ensure the ventilation effect.

The use of three air inlets and curtains must match the fan

The size of the air inlet opening should be matched with the fan. The purpose is to make the coop's ventilation even and effective, and the static pressure in the house is appropriate to ensure the wind speed of the house. The basis for adjusting the air inlet size in the house is mainly determined by the wind speed inside the house, but the air inlet must be opened symmetrically. At the same time, the deflector must be installed, and the angle of the deflector should be parallel to the angle of the roof, in order to make it enter the chicken. The fresh air in the house reaches the middle of the roof of the chicken house, and after thorough mixing, it is evenly blown to the flock and avoid blowing the flock.

At the same time, the wet curtain opening size and opening time should be set according to the temperature of the chicken house, and the corresponding ventilation series should be set, and the internal static pressure parameters should also be set. During the use of vertical ventilation and wet curtains, it is necessary to ensure that the temperature difference between the front and rear of the house is less than 6°C and the temperature within the house is even; the cold wind at the wet curtain at the front of the house cannot be directly blown to the flock to avoid cold stress of the flock; The pressure must be within the standard range and must not be so large as to avoid damage to the ventilation equipment.

create a suitable body temperature

Whether the ventilation of the coop is effective and whether the chickens are comfortable can not just look at the temperature displayed by the thermometer and the thermostat, it must be judged according to the temperature of the chicken's body and the performance of the flock: that is, according to the flock's feeding, drinking, and tweeting. Mental status and other aspects are normal to understand the comfort level of the flock. The somatosensory temperature of the flock is different from the temperature measured by the thermometer. The absolute temperature of the flock must be considered in conjunction with the air flow rate, the age of the flock, the gender, and the environmental conditions of the house. The higher the wind speed of the coop, the lower the temperature of the chicken's somatosensory temperature, and the greater the discrepancy between the recorded value of the chicken and the thermometer, and the smaller the age of the chicken, the more pronounced the air-cooling effect caused by the wind speed.
