Dust Net Generation Rate in a Poultry Layer House

Abstract

Dust particle net generation rates, based on the particle concentration data obtained in a commercial poultry facility during a complete laying season of one flock of birds, were calculated and compared to published values. The layer house was mechanically ventilated with a housing capacity for 112,000 caged birds. Two seasonal (hot and cold) ventilation rates were used at different times during the 14 weekly sample periods that are included in this study. The daily lighting scheme in the house consisted of 17 lighted hours followed by 7 darkened hours.
