The hatchery should be equipped with a well-designed ventilation system to ensure clean and fresh indoor air. It is recommended that the washing rooms and walkways operate under negative pressure to prevent contamination from spreading to other areas. However, for most other rooms, positive pressure ventilation is preferable, as it helps maintain a controlled environment and prevents external contaminants from entering. Negative pressure ventilation should generally be avoided except in specific zones where it is necessary.
The hatching area and incubation room should be considered as a separate unit, each requiring its own dedicated ventilation system to maintain optimal conditions. For facilities with better resources, a positive pressure filtration ventilation system is highly recommended. This type of system ensures that incoming and outgoing air do not mix or contaminate each other, maintaining a hygienic and stable environment throughout the hatchery. Proper ventilation is crucial for disease prevention, air quality control, and overall operational efficiency.
