Improving Air Quality in Broiler Rooms Using an Electrostatic Particle Ionization System

Highlights An EPI system reduced PM and bacteria in broiler houses by up to 50% 48%, on average, respectively. The had no significant effect animal productivity. performance of the decreased towards end rearing cycle. Abstract. Air quality poultry operations is important for human health. This study evaluated an electrostatic particle ionization (EPI) improving air mechanically ventilated rooms (11.7 m long, 6.4 wide, 2.9 high), each with 800 birds. impact levels particulate matter (PM), ammonia (NH3), hydrogen sulfide (H2S), as well performance. On fractions (PM1, PM2.5, PM4, PM10, PM15) approximately 50%. Average reductions total were 40% No reduction was observed NH3, measurable H2S detected during entire period. effects feed conversion ratio mortality observed. Reductions culturable over time, which could possibly be due increased contaminant concentration, ventilation rate, accumulated dust collection surfaces Further assessments are required determine if additional units or improve efficiency system. Overall, airborne improved houses. Keywords: Animal performance, quality, Bacteria, Broiler houses, Electrostatic ionization, Particulate matter.
