Objectives: There are many hazardous agents at livestock farms. In particular, gases can be detrimental to bothworkers and animals. This study evaluated ammonia and hydrogen sulfide concentrations in broiler hen barnsand beef cattle barns according to sampling location and height. Methods: Three broiler hen barns and three beef cattle barns were selected for gas monitoring in this study. Ammonia and hydrogen sulfide concentrations were measured using a direct-reading instrument which couldmeasure the target gases simultaneously. Gas monitoring was conducted at human breathing height and animalbreathing height at three points in each livestock farm. Results: Ammonia concentrations at the broiler hen barns ranged from 3.3 to 12.5 ppm by sampling locationand height, but hydrogen sulfide was not detected. In the beef cattle barns, ammonia ranged from 3.1 to 16.3ppm and low concentrations of hydrogen sulfide were detected at some animal breathing heights. The gasconcentrations detected at each livestock farm were significantly higher in the animal breathing zones thanin human breathing zones (p<0.0001). Conclusions: We found a difference in gas concentrations between human breathing zones and animal breathingzones. Gas monitoring should be conducted to improve the related environment considering both workers’ andanimals’ health and safety.
