Farmed Pig Pain Recognition Behavioural Signs

Recognising pain in pigs requires knowledge of species-specific behavioural indicators - early identification enables faster intervention.

Key Facts

Pigs are stoic animals that may not display obvious pain signs until condition is advanced
Behavioural pain indicators include grinding teeth, altered posture, gait changes, and reduced social interaction
The Porcine Grimace Scale is a validated tool assessing facial expressions for pain assessment
Ear position, body posture, and vocalisation patterns all contribute to pain assessment
Farm staff training in pain recognition significantly improves detection rates
Routine analgesic use for painful procedures including castration and tail docking remains inconsistent

Welfare Considerations

Pain recognition in pigs is a welfare-critical competency for all farm staff. Early identification of pain enables earlier intervention and reduces duration of suffering. Validated tools like the Porcine Grimace Scale provide objective assessment that reduces reliance on subjective observation. Investment in farm staff pain recognition training has direct welfare benefits.
