Pig Transportation Welfare and Pre-Slaughter Management

The journey from farm to slaughter plant is a significant welfare event for pigs. Understanding and improving transportation and pre-slaughter management reduces stress and injury at a critical moment.

Key Facts

Transport stress is cumulative — a pig that has been mixed, transported, and held in unfamiliar lairage arrives at slaughter significantly more stressed than a farm-raised pig
Mixing of unfamiliar pigs during loading and at lairage triggers fights that cause skin injuries and elevated cortisol
Stocking density during transport affects welfare — pigs need enough space to lie down during journeys longer than 4 hours
Lairage (holding pens at the slaughter plant) requires appropriate temperature, ventilation, water access, and minimal noise
Stress during pre-slaughter handling increases dark, firm, dry (DFD) pork defects — creating an economic incentive aligned with welfare
Low-stress handling training for transport and lairage staff measurably reduces injury rates and improves animal behavior

Welfare Considerations

Pre-slaughter welfare is often considered separately from on-farm welfare, but it represents the final welfare experience of the animal's life. Pigs that have lived reasonable lives on farms can experience acute distress during transportation and pre-slaughter handling that constitutes significant suffering. Keeping pigs in their established social groups through loading and transport, minimizing journey times, providing appropriate conditions at lairage, and training handling staff in low-stress techniques addresses this welfare bottleneck. Welfare-certified supply chains increasingly audit pre-slaughter handling as a required component of comprehensive welfare.

What You Can Do

Support pork from supply chains that include pre-slaughter welfare monitoring and handling standards
Advocate for journey time limits, stocking density requirements, and lairage welfare standards in legislation
Reduce pork consumption or shift toward certified producers who address the full lifecycle welfare of their animals
Ask retailers about pre-slaughter welfare standards in their pork supply chains
