Pain recognition in farm animals is a critical welfare skill; evidence-based pain assessment and treatment significantly reduces suffering across all farmed species.
Pain recognition and treatment in farm animals has been transformed by validated assessment tools and improved analgesic options. Grimace scales — identifying specific facial muscle activation patterns associated with pain — provide objective, standardized assessment that does not rely on behavioral interpretation alone. Combined with behavioral scoring (posture, movement, social behavior, feeding), these tools allow confident pain identification and treatment decisions. NSAIDs are effective, affordable, and have reasonable withdrawal periods for most farmed species. The remaining barriers are primarily cultural — the belief that farm animals do not feel pain as intensely as companion animals, and concerns about additional cost. Evidence consistently shows that analgesia improves recovery, reduces mortality, and supports production outcomes, making the business case alongside the welfare case compelling.
