The ventilation system in a broiler cage is critical in maintaining a comfortable working environment for the broilers. It is responsible for the removal of spent air, moisture, and scheduled gases like ammonia from the cage. This system will also control the temperature and humidity in the cage at optimal levels for the well-being of the birds. A good ventilation system is capable of minimizing respiratory disease challenges and enhancing the growth rate of the broilers. There are different types of ventilation systems such as natural ventilation and mechanical ventilation.
