The results of this study suggest that transporting pigs in pot-belly trailers rather than in straight decks results in an increased incidence of pigs exhibiting indicators of stress on arrival at the slaughter plant and that this increased incidence may, in part, be due to greater difficulty associated with unloading pigs from the pot-belly trailers. However, losses during transport for the two trailer types were similar. The greater distance pigs were moved at the farm prior to loading the higher the incidence of indicators of stress and non-ambulatory pigs at the farm after loading.
