The swine industry has progressively adopted a segregated early weaning management system, necessitating the transport of piglets at 14-21 days of age. Transportation can be a severe stressor especially for young piglets, which show weight loss due to dehydration and food withdrawal. The responses and tolerances of SEW piglets to transport are not well understood. Most previous transport work focused on slaughter hogs. Weaning itself, especially at an early age, affects the piglets performance as they are slow to develop normal feeding patterns and consequently have a compromised feed intake. When weaning coincides with transport, the stressors are additive, increasing the detrimental effects on post-weaning performance. Transport induces fatigue, dehydration and altered behavior patterns in all seasons and can add to the stress of weaning. Each season affects the piglets in different ways and to different degrees. The cold temperatures during winter transport changed piglet behavior and physiology, encouraging lower levels of activity and decreased ear and rectal temperature. The lower piglet density changes were most apparent after 12 hours of transport were exacerbated. Higher levels of resting, indicative of fatigue, were noted for 3 days post-transport. Average daily gain (post recovery) was lowest in winter and 76 % of “poor doers” (less than weaning weight after 7 days) were observed in the winter. Piglets transported in the summer were also observed to rest more frequently into day 2 post transport, indicting that hot summer transport also induces fatigue. Fall transport, possibly because of the large range in temperature produced the greatest changes in behaviors indicative of stress. Sitting was more frequently observed in the fall and higher drinking frequencies were extended into day 2 indicating that the piglets were not able to meet their water consumption needs on day 1, unlike piglets observed in other seasons. Transported piglets, irrespective of duration of transport and season showed some behaviours associated with transport stress including increased resting, sitting and drinking.
