Pathological Manifestations Rendering Pigs and Cattle Unfit for Transportation in Denmark.

EU regulations concerning the evaluation of animals' fitness for transportation are in several ways rather vague, which leaves room for individual interpretation of the legislation with a potential negative impact on animal welfare. In order to guide interpretation of the unclear statements within the legislation, all forensic case files handled during a 10-year period (2014-2023) on Danish pigs and cattle that had been declared unfit for transportation and subsequently reported to the police, were evaluated. A total of 327 case files addressing 428 animals were examined. Most pigs were declared unfit for transportation due to the presence of severe open wounds, whereas lameness was the main reason for cattle being deemed unfit. In conclusion, most wounds rendering both pigs and cattle unfit for transportation measured at least 3 cm in diameter, apart from those located in sensitive areas, e.g., tails. Manifestations rendering pigs unfit for transportation due to lameness were primarily joint lesions, whereas fractures were the dominant cause of lameness in cattle. Therefore, the focus should be on these manifestations when assessing animals for transport fitness.
