Validated pain assessment tools now exist for cattle, sheep, pigs, and horses. Using these tools improves welfare by enabling earlier recognition and more effective treatment of animal pain.
Untreated pain is both a welfare failure and an economic problem. Animals in pain eat less, grow more slowly, and are more susceptible to disease. The development of validated pain scoring tools has transformed veterinary and farm practice by providing objective, repeatable measures that remove the guesswork from pain recognition. Despite this, surveys consistently find that pain relief is under-used in farm settings — particularly for procedures like castration, dehorning, and lambing complications. Training farm staff to use pain scales and creating protocols for proactive pain management address both welfare and production goals.
