The Importance of Proper Ventilation in Poultry Houses

Effective ventilation in poultry houses is crucial for ensuring the health and performance of the flock. Mark Cook, the National Sales Manager for Cumberland, a leading supplier of poultry production equipment, outlines essential practices to create an optimal environment for poultry.

The Impact of Minor Environmental Changes

Cook explains that minor adjustments in temperature, wind speed, or humidity can profoundly affect flock performance. “Even under-ventilating by a few thousand cubic feet every five minutes can lead to increased ammonia levels, damp floors, and high humidity,” he warns. “These factors are detrimental to bird health and productivity.”

Maintaining peak fan performance and minimizing air leaks around vents and tunnel doors are foundational to mitigating these issues. “A well-sealed building with appropriate static pressure is key to a successful poultry environment,” he adds.

Temperature, Humidity, and Airflow Guidelines

When it comes to young birds, Cook emphasizes the necessity of sealing vent and tunnel doors to direct airflow within the poultry house. “Getting them off to a good start and maintaining ideal house conditions is vital for achieving optimal performance throughout their lifespan.”

As birds mature, the need for increased airflow becomes more pressing. “Ensuring wind speed in the building serves as a cooling mechanism, which can be achieved through well-maintained belts, clean shutters, and efficient fans,” Cook advises.

Identifying Cold and Hot Spots

Air leaks are a primary cause of cold spots within poultry houses. Cook notes that improper placement of temperature probes can lead to misleading readings, as probes placed too close to heaters may misrepresent the actual temperature. “It’s crucial to correctly locate temperature probes and regularly maintain them to ensure accuracy,” he states.

During the summer months, air typically enters through the evaporative cooling system and is expelled by fans. “In this case, while hot spots may be less common, inadequate wind speed can cause temperature build-up, making it essential to enhance fan performance,” he elucidates.

To improve existing fan efficiency, Cook recommends replacing worn belts, cleaning fan shutters, and assessing evaporative cooling pads for dust and mineral accumulation.

Responding to Environmental Challenges

In cold weather, he suggests recalibrating or replacing temperature probes, cleaning heat reflectors, and checking gas pressure to determine if older heating units require replacement.

Spotting Environmental Problems Early

“Reading the birds is essential,” Cook says. “If they are huddled in the center of the house, it’s likely too cool; conversely, if they are gathered against the walls, it could be too hot.” Monitoring daily water consumption can provide additional insights into bird health, as a sudden decrease might indicate sickness or other issues.

“Check for caked or wet litter,” Cook advises. “Damp floors usually signal insufficient ventilation, necessitating the operation of fans to introduce more air. Additionally, it’s important to remove excess carbon monoxide, humidity, and ammonia to ensure adequate airflow over the birds for cooling.”

Cook concludes that effective ventilation is perhaps the most significant factor in maximizing flock performance. “Producers generally grasp this, but remember, each day presents unique challenges requiring tailored approaches,” he notes.
