Description: Odour persistence values were determined for seven odour sources: broiler manurelayer manure dairy manure swine manure and exhaust air from. pig gestation, nursery, and finisher facilities. These values were compared to that of a reference livestock odour, n-butanol.Persistence values ranged between -0.87 for stored swine manure and -1.59 for exhaust air from a pig nursery unit.Swine odours and dairy manure odour were the most persistent. The data suggest that odour dispersion models need to includeodour persistence values to determine minimum distance separation (MDS) values for livestock operations.

Keywords: animal odour origin, persistence, concentration, odour intensity
