Abstract | External and internal air temperatures were measured continuously for one year (between January 1999 and December 1999) in 48 piggery buildings in South Australia using self contained data-loggers with built-in sensors. Data was consolidated to correspond with the four seasons. Regression values between the external and internal temperatures were calculated for individual buildings for each season. Data was also collected on major housing features, including configuration of the buildings and management factors employed in them. The information collected was then analysed to quantify the effects of housing and management factors on the resulting environmental control using a multi-factorial statistical model. The overall mean air temperatures in all buildings corresponding to the four seasons were; 24°C (summer), 20°C (autumn), 18°C (winter), 21°C (spring) across all buildings. The regression values between external and internal temperatures were affected by the season, type of insulation material used in the buildings, the availability of extra heating or cooling equipment, height of buildings, roof pitch (angle), type of ridge ventilation control employed, stocking density, age of buildings and number of pigs housed per building. The effects of housing and management factors on thermal control capacity of buildings were quantified. These findings should aid the construction of better designed livestock buildings resulting in improved welfare and production efficiency in piggery buildings. |
