Dehorning and disbudding of cattle causes significant acute pain; evidence-based analgesic protocols dramatically reduce welfare harm from these routine practices.
Cattle feel significant pain during dehorning - physiological responses including cortisol elevation, increased heart rate, and behavioral pain indicators are well documented. The combination of local anaesthetic and NSAID provides near-complete pain mitigation during and after the procedure. There is no ethically defensible reason to perform dehorning without analgesia when effective, affordable options exist.
