However, these vehicles incorporate
both external and internal ramps and a fixed upper deck,
factors that have been associated with increased mortality
rates in Europe (Riches et al., 1996; Barton-Gade et al.,
2007). To date, few studies have examined the effect
of season and truck design on pig welfare, especially
under extreme weather conditions as found in Canada.
Therefore, the objective of this study was to assess the
welfare of market-weight pigs through their behavior
during transport on different trucks in 2 seasons.
