The objectives of this project were to study stressors experienced by market\u00a0pigs during handling and transport, to identify components of these stressors that can be modified, and to assess\u00a0whether modifying these components can reduce stress and\/or improve the ability of pigs to recover. This researched showed that the use of double deck hydraulic trailers resulted in less stress and better meat quality compared to pot\u00a0belly trailers, likely due to the absence of internal ramps and reduced handling stress at loading and\u00a0unloading. In addition, pigs spent more time standing during transport in winter, likely to conserve heat by minimizing contact with\u00a0the trailer floor. Heart rate and internal body temperatures were also higher in winter, suggesting increased\u00a0metabolic rate.\u00a0In eastern studies, hot summer temperatures and shorter transport times resulted in increased stress on pigs\u00a0and higher levels of PSE meat traits, while in\u00a0western studies, long transport times in winter resulted in greater stress compared to summer conditions. Indeed, it was shown that pigs transported long distances in winter showed increased drinking in lairage, indicating dehydration and\u00a0produced more hams with RSE and DFD meat characteristics. Lastly,\u00a0there is significant variation in temperature and humidity conditions between compartments on all trailers\u00a0studied, with upper rearward compartments having lower temperatures and central front compartments\u00a0being warmer.\u00a0Results of this research have implications for industry, regulators and for future\u00a0research to improve transport conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"
