Sheep Transport Welfare: Science & Best Practice

Sheep Transport and Welfare

Transport is one of the highest-stress periods in the lives of sheep. Unfamiliar environments, motion, vibration, noise, temperature extremes, and the disruption of social groups create a complex stress challenge. UK and EU law regulates transport conditions; science provides evidence for best practice that goes beyond legal minimums.

The Transport Stress Cascade

• Loading: Handling and movement into unfamiliar vehicle causes acute cortisol elevation and heart rate increase
• Journey: Vibration, temperature changes, noise, motion sickness, and social disruption cause sustained stress
• Unloading: Further handling stress; unfamiliar environment at destination
• Lairage: Rest period before slaughter or further movement; social disruption from mixing unfamiliar groups

Legal Requirements (UK)

• Animals must be fit for transport — no injured or sick animals unless for veterinary treatment
• Space allowances per animal (floor area kg/animal) specified for different journey categories
• Journey time limits (8 hours for unimproved sheep without water access; extended journeys require rest, water, feed)
• Temperature management and ventilation in vehicles
• Experienced handlers and appropriate vehicle equipment

Welfare-Positive Practices

• Pre-transport preparation: Withholding feed (reduces travel sickness) while ensuring adequate water before loading
• Mixing avoidance: Keep established groups together wherever possible; mixing unfamiliar sheep increases aggression stress
• Low-stress loading: Race and ramp design, appropriate lighting, calm stockmanship, and avoiding electric goad use
• Stocking density: Adequate space for all animals to lie simultaneously; overcrowding reduces welfare significantly
• Temperature management: Ventilation to prevent heat stress; bedding in cold conditions
• Journey time minimisation: Shortest practical routes; minimising stoppage time

Indicators of Poor Transport Welfare

• High mortality rate during or after transport
• Bruising and injury at slaughter (Dark Firm Dry/DFD meat — stress indicator)
• Injuries from poor vehicle design or loading
• Respiratory disease outbreaks post-transport

Key Takeaways

Transport is an unavoidable but manageable welfare challenge for sheep. Low-stress handling, appropriate social grouping, correct stocking density, temperature management, and minimising journey times significantly reduce the welfare burden of transport on one of the most commonly moved farm animal species.
