Pain Recognition in Farm Animals: Tools and Training

Recognising pain in farm animals is fundamental to welfare but challenging, requiring validated assessment tools and trained stockpeople.

Key Facts

Farm animals evolved to conceal pain as protection against predation
Facial Action Units (grimace scales) have been validated for pigs, cattle, sheep and horses
Locomotion scoring provides standardised assessment of lameness in cattle and pigs
Stockpeople trained in pain recognition identify and treat animals more effectively
Financial incentives aligned with welfare outcomes improve proactive pain management

Welfare Considerations

Pain recognition is the foundation of all welfare intervention. Animals suffering pain that is not identified receive no treatment, resulting in prolonged unnecessary suffering. Grimace scales validated using physiological pain markers allow rapid visual assessment of pain levels without specialist equipment. Implementing pain recognition training alongside financial incentives for early reporting and treatment creates systems where animal pain is detected and addressed promptly, dramatically reducing suffering duration.

What You Can Do

Support training programmes in livestock pain recognition for stockpeople
Advocate for mandatory pain recognition competency in farm assurance standards
Use validated grimace scales and locomotion scoring in farm management
Support certification schemes that audit pain management protocols
