Long-distance transport causes significant welfare harms to livestock including dehydration, exhaustion, injury, and disease.
Transport stress involves multiple simultaneous stressors: social disruption, novel environments, motion, food and water deprivation, thermal extremes, and restraint. Cattle deprived of water for 24 hours show severe dehydration. Mixing groups causes aggression and injuries. Pneumonia after transport is extremely common due to immunosuppression. Short journey times, proper lairage, and carcass meat trade over live animals significantly reduce welfare harms.
