Pig Transport to Slaughter: Reducing the Last Journey Welfare Cost

Transport to slaughter is one of the most welfare-challenging phases in commercial pig production, involving unfamiliar confinement, social mixing, thermal stress, and the cumulative stressors of a journey that ends in slaughter.

Key Facts

Pigs transported for slaughter show elevated cortisol, skin lesions from fighting, and metabolic changes indicating significant acute stress during the journey
Mixing unfamiliar pigs during loading causes fighting that produces skin injuries affecting both welfare and meat quality — all-in all-out transport with established groups reduces this significantly
Journey time limits for pigs vary significantly between jurisdictions — the EU limits most journeys to 8 hours, with extensions permitted under specific conditions
Lairage — holding pens at slaughter facilities — represents another welfare risk phase where temperature, space, noise, and social disruption all affect stress levels
On-farm slaughter eliminates transport stress entirely — growing availability of mobile slaughter units makes this option accessible to a wider range of producers

Welfare Considerations

Transport welfare improvement requires action at every stage of a multi-phase journey: careful loading that minimizes mixing and rough handling, appropriate vehicle conditions during transit, and well-managed lairage upon arrival. Each phase has documented welfare solutions — the challenge is achieving consistent implementation across a supply chain with many operators and limited oversight. Regulations that specify maximum journey times, vehicle standards, and lairage conditions provide a floor below which welfare cannot fall, while certification schemes drive performance above this minimum.

What You Can Do

Support pork from producers who use short transport journeys and documented welfare-conscious transport protocols
Advocate for maximum journey time limits that reflect pig welfare science rather than economic convenience
Support on-farm slaughter infrastructure development as a high-welfare alternative to long-distance transport
Choose welfare-certified pork from schemes that audit transport and lairage conditions alongside farm welfare
