摘要：Airborne bacteria and particulate matter (PM) emitted from animal houses may harm the environment and threaten on-farm and off-farm bio-security. Airborne transmission of PM and bacteria occurs more easily between double-tunnel ventilation layer hen houses with side-to-side arrangement due to the layout of inlet and outlet, and the accumulation of airborne contaminants in the intermediate region. This study practically applied shading nets for covering exhaust area and water disinfection for evaporative cooling system to prevent airborne transmission of PM and microbial aerosols between layer hen houses.
