Dehorning and disbudding cause significant pain in cattle but are widely practiced for safety reasons. Proper analgesia and technique can dramatically reduce suffering.
Dehorning and disbudding represent an ethical paradox in dairy farming: they are performed to prevent injury (a welfare goal) but cause significant pain (a welfare harm). The resolution lies in ensuring that when these procedures are necessary, they are performed with appropriate analgesia. Research unequivocally demonstrates that cornual nerve blocks eliminate acute procedural pain, and NSAIDs (meloxicam, flunixin) address post-procedural pain for 12-24 hours. The combination provides substantially better welfare than either alone. The longer-term welfare solution is to eliminate the need for dehorning through breeding for polled genetics, a strategy increasingly adopted in progressive dairy systems. Some certification schemes and retailers already require polled genetics breeding programs as part of their welfare standards. Until horn-bearing genetics are phased out, mandatory analgesia should be a universal requirement.
