Ventilation systems for poultry farming

1. Role and Importance
Ventilation: Side wall air intakes allow fresh air to enter the coop and exchange with the dirty air in the coop, keeping the air fresh and helping to reduce the incidence of disease in chickens.
Temperature regulation: By reasonably controlling the opening size and number of air intakes, the temperature in the coop can be adjusted to ensure that the chickens grow in the most suitable environment.
Humidity control: Air intakes help to reduce the humidity in the coop, especially during the wet season, which can reduce the discomfort caused by excessive humidity.
2. Design and configuration
Size and shape: The size and shape of the side wall air intakes should be determined according to the size, feeding density and ventilation needs of the chicken house. The common shapes are rectangular, square, etc., and the size is flexibly adjusted according to actual needs.
Quantity and layout: The number of air intakes should be sufficient to ensure even air circulation in the coop. In terms of layout, the air intake should be evenly distributed on the side wall of the chicken house to avoid local poor ventilation.
Material and durability: The air inlet should be made of durable and corrosion-resistant materials, such as rubber products processed by injection molds, to ensure its long-term stable operation.

3. Use and management
Open and close: Open or close the air intakes according to the temperature, humidity and ventilation requirements inside and outside the coop. In the cold season, the opening amount of air intake should be appropriately reduced to prevent cold air from directly entering the coop.
Maintenance and cleaning: Regularly clean the debris and dust near the air intake to ensure that it is unimpeded. At the same time, check the tightness and integrity of the air intake, and repair it in time if there is damage.
Monitoring and adjustment: Use anemometer, thermometer and other instruments to monitor the air flow and temperature changes in the chicken house, and adjust the opening size and number of air intakes in time according to the monitoring results.
4. Precautions
Avoid excessive negative pressure: excessive negative pressure may lead to poor air circulation in the chicken house, affecting the ventilation effect. Therefore, the number and power of the exhaust fan should be reasonably controlled to maintain an appropriate level of negative pressure.
Prevent the cold wind from blowing directly: In the cold season, the cold wind should be avoided from blowing directly to the chickens to reduce the stress response caused by the cold. This can be achieved by adjusting the position and opening of the air intake.
Consider the type of coop: Different types of coop (caged coop, flat coop, etc.) may have different requirements for air intakes. Therefore, when designing the air intake, the type and feeding method of the chicken house should be fully considered.
To sum up, the design and configuration of the side wall air intakes of the chicken house in the farm are very important for the environmental control in the chicken house and the health of the chickens. Through reasonable design, configuration and management, it can ensure that the air circulation in the chicken house is smooth, the temperature is appropriate, the humidity is moderate, and the chickens are provided with a good growth environment.
