Ease of handling, physiological response, skin lesions and meat quality in pigs transported in two truck types
A total of 1,728 pigs were transported to slaughter using two double-decked trucks, one featuring a hydraulic deck (HD) to load and unload the upper level and the other presenting a fixed upper deck (FD) only accessible by a ramp. The aim of the research was to evaluate the effects of the loading and unloading system of the truck on behaviour, blood parameters (cortisol, lactate and creatine kinase [CK]), skin lesions and meat quality traits. The use of HD resulted in easier and faster loading (P < 0.05 for both) compared with the FD. Blood cortisol levels were influenced by the loading/unloading system, with lower (P < 0.05) levels being found in pigs using HD transport when compared to those using FD transport. Truck type had no effect on the incidence of skin lesions and pork quality in this study (P > 0.05). It can be concluded that the use of the truck model featuring the upper hydraulic deck should be recommended to ease of handling at loading improving animal welfare and reducing the work load of handlers.
