Deep Litter Ventilation System Biological Mechanism Overview



Deep litter system operates as a controlled biological fermentation environment where manure and bedding materials interact under microbial decomposition. 

Oxygen availability determines whether the system remains aerobic or shifts into anaerobic conditions.

Ammonia emission increases sharply when oxygen transfer drops below 0.18 m³/kg bedding dry matter, causing respiratory stress in poultry flocks.

Air Exchange Control Minimum Ventilation Strategy



Minimum ventilation ensures continuous removal of moisture and gases even during cold climate operation. It prevents ammonia accumulation at bird respiratory height.

Humidity Regulation Litter Moisture Balance Control



Humidity directly affects litter microbial efficiency and ammonia production rate. Excess moisture reduces oxygen penetration and increases pathogen load.

Scientific poultry housing references indicate optimal relative humidity range around 50–70 percent under controlled ventilation environments.
