Ventilation In Chicken House For Poultry Farming Cage plays a vital role and even affects the survival rate of the whole flock. livi Machinery will take you through the automatic ventilation equipment and the area calculation of ventilation equipment in the chicken house.

Ventilation in Chicken House

In the case of a sealed environment in low-temperature chicken houses, introducing fresh air from outside while expelling stale air from inside the chicken house to improve air quality is called ventilation. Ventilation primarily focuses on the later stages of brooding when the chicks are rapidly growing and require a substantial amount of oxygen. With increased feed and water intake, along with increased waste output, ventilation becomes crucial during this period.

Purpose of Ventilation

Elimination of harmful gases and provision of ample oxygen for chicken growth.

Maintaining suitable temperature and humidity levels inside the chicken house.

Reducing the presence of bacteria, viruses, and other pathogens inside the chicken house.

Example:

The oxygen consumption of 60 chickens is equivalent to that of a 120-kilogram person. Assuming each chicken weighs 4 kilograms, then 60/4 = 15 chickens are equivalent to one person. With 1000 chickens, it would be 1000/15 = 67. Each coal stove emits as much carbon dioxide as the oxygen consumption of 1000 chickens. If there are two coal stoves, it would be 2 × 67 = 134 + 67 = 201 people. Assuming 10 chickens are raised per square meter, then 201/100 = 2.01 people per square meter, equivalent to having 2 people per square meter.

Attention:

Proper ventilation can reduce the incidence of diseases such as ascites, respiratory diseases, and E. coli infections. Ventilation is crucial in controlling the indoor air environment, especially during the later stages of chicken growth. Poor ventilation can lead to hypoxia, which is a direct cause of diseases like viral infections, respiratory diseases, and peritonitis.

Ventilation Control

Ensure adequate ventilation while maintaining temperature stability. Good ventilation should be maintained from the first day of chick placement.

Focus on ventilation during sunrise, as it helps alleviate insufficient ventilation during the latter part of the night and hypoxia caused by chickens’ vigorous activity.

Prevent direct cold drafts from blowing onto the chickens at night to avoid chilling. Ventilation should be uniform throughout the chicken house to prevent dead spots and avoid drafts.

Different ventilation methods should be chosen based on seasonal variations: negative pressure ventilation is preferred during the coldest and hottest seasons, while natural ventilation is suitable for other seasons.

Maintain a consistent airflow inside the automatic chicken house, even in winter, with a recommended airflow velocity of 0.1-0.2 m/s, not exceeding 0.3 m/s, and 0.01-0.05 m/s indicating poor ventilation. In summer, an airflow velocity of 0.5 m/s is optimal, and for open-style coops, 1.0-1.5 m/s is ideal.

Ensure sufficient inlet openings, and direct the guide plates of inlet openings upwards.

Standard Ventilation Volume for Commercial Broiler Chickens

Calculate the ventilation volume for 10 minutes, then determine the exhaust time based on the exhaust volume of the fan, generally not less than 1 minute.

Calculation of Ventilation Volume and Use of Fans:

For example, if there are 4000 chickens with an average weight of 0.5 kilograms, the minimum ventilation volume is: 4000 chickens × 0.5 kilograms × 0.0155 cubic meters/kilogram/minute = 31 cubic meters/minute.
If the exhaust volume of the fan is 17,000 cubic meters/hour, the exhaust volume per minute is 17,000/60 = 283 cubic meters/minute.
In this case, if a fan with a volume of 283 cubic meters/minute is used, the ventilation time required for every 10 minutes is: 31 cubic meters/minute × 10 minutes = 1.1 minutes / 283 cubic meters/minute.
Therefore, for the aforementioned 4000 chickens, a fan with a volume of 283 cubic meters/minute should be used. And the exhaust time should be 1.1 minutes for every 10 minutes to meet the minimum needs of chicken growth.
