Odour and gas emissions from swine operations have been known to be a nuisance to nearby residents. Since most pig barns in Canada have outside manure storage, there are two sources of odour and gas emissions. The possibility of keeping the manure inside the building would reduce the odour and gas emission sources to one. The objective of this study was to develop a two airspace building concept where pigs dung in an enclosed dunging area (EDA) above the slats which could result in an improvement of barn air quality as odours and gases would be contained in the EDA. Air removed from the EDA would be treated with a biofilter to reduce the overall emissions from a swine operation. Four types of openings for the EDA openings were investigated as well as the use of biofiltration for odour removal, pig behaviour and ventilation system. The use of an EDA with a full curtain opening was successful in reducing odour and ammonia concentrations by 20-40% respectively. Further steps to complete this project include full data analysis of the pig behaviour and odour and gas measurements based on the results obtained at the PSCI.
