Farmed Pig Pain Indicators and Stockperson Training

Recognising pain in pigs requires training stockpeople to read subtle behavioural and postural cues. Validated assessment tools combined with clear treatment protocols reduce the time pigs spend suffering from treatable conditions.

Key Facts

The Pig Grimace Scale uses orbital tightening, nose bulge, and cheek tension to score acute pain 0 to 2
Lameness in pigs is frequently under-treated; surveys show fewer than 40 per cent of lame pigs receive analgesia
Tail biting wounds, foot lesions, and shoulder sores are among the most common pain sources in commercial systems
Long-acting meloxicam formulations reduce cortisol and improve activity levels in pigs with confirmed lameness
Stockpeople who receive pain recognition training intervene 50 per cent faster than untrained peers in controlled studies

Welfare Considerations

Pigs experiencing chronic pain reduce feed intake, lose body condition, and withdraw from social interaction — signs that experienced observers can detect but casual observers miss. Regular pen-walking with explicit pain assessment checklists improves detection rates significantly. Welfare-centred farms integrate pain assessment into daily health rounds, maintain a treatment log, and involve the vet in setting clear trigger thresholds for analgesic use. Addressing the root causes — adequate space, enrichment, dry bedding, and floor quality — reduces the incidence of pain-causing conditions.

What You Can Do

Support pig welfare organisations developing and distributing free pain recognition training to farmers
Ask pork retailers to require evidence of stockperson welfare training in their supply chain audits
Encourage veterinary surgeons to include pig pain scoring in practice-led herd health programmes
Advocate for mandatory analgesia requirements for tail docking and other surgical procedures on farms
Choose pork from higher-welfare certified farms that publish stockperson training standards
