The pigs were transported from the PSC Elstow Research Farm, and involved approximately 8 hours of travel to the Maple Leaf plant in Brandon. Pigs were loaded in the evening and transported overnight to arrive at the packing plant at 6 am. Trials were conducted in both winter and summer. The truck used for transportation was a three-deck dual (cattle and pigs) purpose, pot-belly trailer. The temperature conditions pigs are exposed to during transport vary considerably between seasons and among compartments within a vehicle. It was found that it may be possible to better standardize these temperature variations by changing ventilation and insulation values in each section/compartment of the trailer. The results found in this study will provide direction for important studies in the future.
