Abstract
Aerial pollutants within piggeries exacerbate endemic respiratory diseases of pigs, e.g. atrophic rhinitis (AR) and enzootic pneumonia (EP). Control of these diseases by medication, vaccination or by eliminating specific pathogens has proved costly and often ineffective. Disease models suggests that a more cost effective control strategy would be to improve air hygiene. This study will quantify the effects of gaseous (NH3, H2S) and particulate (ovalbumin, endotoxin) aerial pollutants on the specific and non-specific defence mechanisms of the upper and lower respiratory tract, and identify and analyse the role of these pollutants in the aetiology of AR and EP. The project will establish air hygiene tolerance limits for maximising health, productivity and welfare.
