While factors such as nutrition and biosecurity are often highlighted, the importance of proper ventilation in poultry houses cannot be overstated. Ventilation is the cornerstone of environmental management, influencing the wellbeing and performance of the flock. Control of Humidity Elevated humidity can foster pathogen proliferation and result in soggy litter, facilitating disease outbreaks. Proper ventilation maintains ideal moisture levels, keeping the litter dry and lowering the chances of infections like respiratory illnesses. Ammonia and Gas Removal Poultry bedding generates ammonia, which can ascend to dangerous concentrations if not adequately controlled. High ammonia levels can harm the birds' respiratory systems, weakening their immunity and hindering growth. Ventilation mechanisms efficiently extract ammonia and other noxious gases, enhancing air quality and avian health. Dust and Dander Control Poultry environments can become laden with dust, with minute particles impacting both the birds and caretakers. Mechanical ventilation systems aid in diminishing dust buildup, thereby elevating overall air purity. Fresher air reduces respiratory complications and boosts the flock's respiratory wellbeing. Regulation of Temperature Avian species are especially vulnerable to shifts in temperature. Excessive heat can cause thermal stress, decrease feed consumption, and even prove lethal. Conversely, during colder periods, insufficient airflow may create moist, frigid environments that make birds susceptible to respiratory ailments. Effective ventilation systems stabilise indoor climates, providing a pleasant setting for the birds. WHY VENTILATION MATTERS VENTILATION
