Abstract
It has long been recognised that many environmental factors affect the prevalence and severity of pig diseases. This is particularly true for respiratory diseases (pneumonia and pleurisy), which are spread not only directly from pig to pig, but also via aerosol droplets. Environmental factors that assist in the transfer of oro-nasal secretions between pigs are therefore likely to increase the transmission of respiratory infections. Among those factors that have been documented as affecting respiratory disease are air quality, ventilation rate, temperature, pen space per pig, air volume per pig, number of pigs per pen and shed section, type of pen wall, floor insulation, dunging facilities, feeder space per pig, and production system (all-in/ all-out; continuous) (Thomas, 1984; Smith, 1991). Most of these factors are inter-related and cannot be taken as separate entities. Considering the effects of stocking arrangements alone on respiratory disease ignores these other factors and the conclusions may be misleading.
