Transport to slaughter is one of the highest-risk welfare events in a pig's life, involving loading, motion, mixing, and environmental extremes that cause significant stress.
Pigs loaded in unfamiliar groups onto transport vehicles experience fear, aggression from mixing, and motion sickness. Long journeys compound these impacts. The highest-risk phase is loading when falls, injuries, and stress peaks are greatest. Investing in good loading facilities, trained drivers, and temperature-controlled vehicles significantly reduces transport welfare incidents.
