Field Investigation of Airborne Bacteria in Swine House of South Korea-Juniper Publishers
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF DAIRY & VETERINARY SCIENCES Abstract Mean concentrations of airborne bacteria in terms of pig housing type were highest in growing/fattening housing room followed by nursery housing room and gestation/farrowing housing room (p<0.05). The swine house showed the highest levels of airborne bacteria in summer followed by spring, winter and autumn (p<0.05). Overall airborne bacteria which have particle size over 2.1^m (stage1~stage4) accounted for approximately 70% compared to total airborne bacteria regardless of pig housing type. The predominant airborne bacteria in swine house were Staphylococcus spp., Micrococcus spp. and BrevibaciHus spp. Keywords: Airborne bacteria, Pig building, gestation/farrowing, nursery, growing/fattening Introduction Indoor air pollution in swine house by airborne bacteria may be a major cause of decreased pig productivity and respir...
