Description: Dust and ammonia (NH3) emissions from confined swine operations are major concerns to the industry and to the public. Various measures to control emissions have been proposed in the literature but very little work has been done to correlate the effect of these measures on the reduction of emissions to the actual reduction of worker exposure. Four different engineering and management measures, including low crude protein diet, canola oil sprinkling in building air space, stored manure pH manipulation, and high-level of cleaning of production room, were evaluated for their effectiveness on reducing NH3 and respirable dust concentrations in swine production rooms. Their impacts on actual exposure of barn workers to these airborne contaminants, as well as on pig performance were also assessed. The study was carried out in six grow-finish rooms located at Prairie Swine Centre Inc. Four rooms were used as treatment rooms while the other two served as control. Five trials were completed, with each trial running for 16 weeks. During each trial, NH3 and respirable dust concentrations were measured every three weeks, both by area and personal sampling. Area sampling was conducted by installing the samplers at fixed locations in the rooms. Worker exposure to dust and NH3 were monitored using a personal sampling gear outfitted on the workers while they perform their normal tasks in their assigned rooms. The results indicated that the canola oil sprinkling could significantly reduce the respirable dust concentrations compared with the control. The NH3 concentration of the rooms fed with low crude protein diet was significantly lower than the control.
