Farm Animal Transport Mortality: Monitoring, Prevention, and Welfare Standards

Transport mortality represents the most visible welfare failure in livestock transport, yet rates remain unacceptably high in many systems. Prevention through better management and standards reduces this preventable suffering.

Key Facts

Transport mortality rates vary enormously by species, condition, journey duration, and management quality
Poultry transport has among the highest mortality rates - up to 0.3% of birds die during catching, transport, and lairage
Heat stress during poultry transport in summer significantly increases mortality above annual averages
Pigs are susceptible to transport stress syndrome (porcine stress syndrome) which can cause sudden death
Cattle deaths during transport are often from injuries sustained during loading and unloading
EU regulations require transport mortality to be recorded and reported as part of vehicle records
Dead on arrival (DOA) rates at abattoirs provide a useful welfare monitoring metric for transport quality

Welfare Considerations

Transport mortality is the most visible and undeniable welfare failure in livestock transport - every dead animal represents not just commercial loss but a welfare failure that was very likely preventable. The welfare case for transport mortality reduction is clear, and the commercial case is strong, yet mortality rates remain significant across species. The most preventable causes are well-documented: heat stress in summer poultry transport, loading injuries from poor facility design and handling, and fitness-to-travel failures where compromised animals are transported when they should not be. Monitoring DOA rates as a welfare indicator and investigating causes rather than accepting mortality as inevitable are the foundational management responses. Transport mortality is a welfare emergency that occurs repeatedly and systematically - and that demands systematic prevention.

What You Can Do

Support mandatory reporting of transport mortality data by species and cause as a welfare transparency measure
Advocate for fitness-to-travel requirements to be rigorously enforced - unfit animals must not be transported
Support investment in loading and transport facility improvements that reduce injury during loading and unloading
Encourage poultry transport schedule optimization during extreme heat to reduce heat-related mortality
Choose meat and poultry from suppliers with documented low transport mortality rates as part of welfare certification
