Ventilation and cooling systems are among the most important aspects of poultry farming. In poultry houses, ventilation is essential not only for removing ammonia, carbon dioxide, moisture, and gases produced by the birds, but also for bringing fresh air that is needed. In hot climates or summer months, cooling systems like fans, evaporative coolers, or air conditioning units are needed to reduce heat stress on the birds. Good cooling and ventilation systems help to enhance the comfort as well as health of the birds, making them grow faster and healthier, produce more eggs, and live longer
