Validated pain scoring systems enable consistent identification and treatment of pain across livestock species, improving welfare outcomes.
Systematic pain assessment is the foundation of effective pain management in livestock. Without reliable scoring tools, pain goes unrecognized and untreated because it does not match human intuitions about how pain should be expressed. The Grimace Scale approach uses facial action units that are measurable, reproducible, and correlate with known pain states. Training farm staff and veterinarians in validated pain scoring significantly increases rates of analgesia provision and improves welfare outcomes. Integrating pain scoring into daily stock checks transforms pain management from reactive to proactive.
