Long-distance transport of farm animals is a significant welfare concern, involving prolonged confinement, thermal stress, hunger, and social disruption. Evidence for reducing journey times has driven regulatory reform.
Farm animal transport welfare is determined by the interaction of journey duration, vehicle conditions, loading practices, and animal vulnerability. Short journeys in appropriate vehicles during moderate weather have limited welfare impact. Problems accumulate with duration: metabolic acidosis develops in stressed cattle and pigs over extended journeys; heat stress during summer transport can cause heat stroke and death; prolonged standing without rest increases limb injury and fatigue. The 2021 UK government consultation on live animal exports identified reducing journey times as the primary evidence-based intervention. Slaughter closer to the farm of origin is the welfare-optimal solution, reducing transport and allowing animals to be killed in familiar-species company. The ongoing debate over live export versus carcass trade has animal welfare at its centre: live export subjects animals to the full journey and conditions at destination slaughterhouses, which may be below UK standards.
