Pig Welfare and Welfare and Pain Recognition Advanced

Advanced pain recognition in pigs is now achievable through automated tools, validated scales, and trained stockpeople, transforming welfare outcomes.

Key Facts

The Piglet Grimace Scale reliably identifies acute pain in young pigs from facial expressions
Automated grimace scale scoring using AI achieves 85% accuracy compared to trained human assessors
Ear position and tail posture provide reliable welfare indicators in finishing pigs
Lameness scoring in pigs using gait analysis identifies lame animals needing treatment
Multi-parameter welfare assessment combining behavioural and physiological measures is most reliable

Welfare Considerations

Advanced pain recognition enables early identification and treatment of pig pain. Investing in training and technology that improves pain recognition prevents prolonged suffering.
