摘要：The aim of this study was to determine the concentration level of ammonia (NH3), nitrous oxide (N2O), hydrogen sulfide (H2S), and carbon dioxide (CO2) in two different fattening pig houses operated with slatted floor and straw flow system. The field study was performed for three day. One large-scale pig house with capacity of 230 pigs operate with deep litter manure system under the fully slatted floor and one small-scale pig feeding operation with capacity of 200 pigs operated by scraper and straw flow system, located at the Iksan city, South Korea, were investigated in this study. Average emissions of gases on the slatted floor pig house measured were 59.8-70.5 ppm NH3, 0.048-0.78 ppm H2S, 453.1-650.8 ppm CO2 and 0.21-0.68 ppm N2O while the concentrations of these gases at straw flow pig house were determined as 28.17-42.53 ppm NH3, 0.11-0.43 ppm N2O, 0.018-0.043 ppm H2S, 400.2-498.3 ppm CO2. In general, result of H2S, CO2, N2O and NH3 emissions from the straw flow system were lower than values for fully slatted floor systems.
