The aim of this study was to evaluate the odor reduction in swine farms by the application of probiotics. A totalof five farms were selected from the preliminary survey based on the management scale, odor gas concentrationlevel, and production efficiency. The application of probiotics consisted of feeding swine high concentrations ofprobiotics, addition of odor-reducing agents in the slurry pit, and the spraying of swine houses. The concentrationof probiotics given per pig per day was above 107 cfu/g. The odor was measured before and after probioticsapplication for 77 days in the swine farms. With the exception of E farm, the odor concentration decreased infour farms with probiotics application. Ammonia and amine concentrations were reduced by 48.24% and 45.37%on average, respectively. The main causes of odor were hydrogen sulfide, p-cresol, and butyric acid. The totalodor activity value was the lowest in D farm, followed by B, A, E, and C farms, respectively in increasing order. In the case of C farm, hydrogen sulfide accounted for 92% of the total odor activity value. In order to verify thereliability and effectiveness of probiotics at the farm site, appropriate application and monitoring should beperformed continuously on the basis of the product quality evaluation system.
