Long-distance livestock transport causes significant welfare harm, with the EU and UK debating reforms to maximum journey times and rest requirements.

Live export for fattening or slaughter subjects animals to the longest and most welfare-compromising journeys, and has been banned for slaughter animals in the UK.
