Animals transported to slaughter face significant stress from crowding, loading, temperature extremes, and journey duration, with welfare impacts proportional to transport time.
Livestock transport is among the most welfare-compromising phases of farm animal life. Animals that have never previously been in vehicles experience loading as an extremely stressful novel experience. Mixing of unfamiliar animals causes aggression. Temperature extremes during transit cause heat stress or hypothermia. Long journeys without rest, water, or food cause exhaustion and dehydration. Journey duration limits and vehicle welfare standards are among the most effective regulatory interventions.
