Odors emitted from pig houses have been a constant root of legal issues in pig farming. These gases are among the main causes of health and mentalstresses to nearby communities, so policymakers and researchers continuously study to reduce the concentration of odorous gases from pig facilities. A continuous field experiment proved that the concentration of odor emissions inside the pig houses is highly dependent on ventilation rate, breedingdetails, and animal activities. However, the standard odor emission rate worldwide widely varies due to differences in pig house designs and ventilationrequirements. Thus, this study aimed to measure the odor emission rates, considering the actual condition of selected Korean pig houses, through fieldmeasurement. The odor measurements were performed at three different pig production facilities without odor abatement technologies. The targetexperimental pig houses were buildings for weaning, growing, and fattening pigs. Results showed that the actual ventilation rate in target pig housesfalls below the standard ventilation requirement of pigs, resulting in high odor concentrations inside the pig houses.
