Road transport is inherently stressful for horses; journey duration, vehicle design, loading methods, and post-journey recovery all significantly affect welfare outcomes.
Horse transport stress accumulates through multiple pathways: the confined vehicle space, postural muscle exertion maintaining balance, noise, vibration, and the challenge of eating and drinking during movement. Long journeys without adequate rest cause fatigue and immune suppression that predisposes to shipping fever. Training horses to load calmly and providing adequate rest, water, and hay during journeys significantly reduces welfare costs.
