Ventilation is an important factor that controls the productive performance of birds. Poor ventilation leads to low weight and food conversion rate, as well as respiratory diseases that increase the mortality rate, reduce the immunity of birds and make them susceptible to bacterial and viral diseases and eventually develop respiratory disease Chronic Respiratory Disease (CRD), which is difficult to treat and causes significant economic losses, and poor ventilation leads to increased incidence of Hock Burn.

What are the main importance of ventilation in poultry houses?
1. Elimination of many harmful gases in the respiratory system of the bird, such as ammonia and gases resulting from the operation of heaters and replace the proportion of carbon dioxide gas by oxygen to allow birds breath well.
2. Heat distribution inside the poultry houses and get rid of excess heat.
3. Distribution of moisture inside the poultry houses and disposal of excess moisture.
4. Get rid of bad dust.

Effects of poor ventilation on the chickens
1. A lot of respiratory problems such as mycoplasma and many more.
2. Inflammation of the membranes of the eye due to the high proportion of ammonia inside the poultry house for poor ventilation.
3. Stressed strong on the chicks and thus cause the decline of immunity and face diseases and underdevelopment.
4. Little feed intake and idle on the farm.

5. High Humidity Within the house and the fungal problems of coccidiosis begin to appear inside the farm.
6. Efficiency of the rate of conversion and food is low and, therefore, we get the weight of a discount.
Effect of good ventilation on the chickens
1. We do not find respiratory problems.
2. Increase the appetite of the bird.
3. Disappearance of the smell of ammonia in the house and reduce the problems of the eye.
4. In the end, the efficiency of the conversion rate rises and we get high weights.
