Dehorning and disbudding of cattle is among the most common painful procedures in livestock farming, yet pain management at the time of procedure remains inconsistent, causing preventable suffering in millions of calves annually.
Disbudding and dehorning cause acute pain that, without adequate analgesia, persists for many hours. The stress response to the procedure involves measurable cortisol elevation, behavioral pain indicators (head shaking, ear flicking, reduced feeding), and physiological changes consistent with significant pain experience. Local anesthetic reduces the acute procedural pain but does not address the post-procedural inflammatory pain that persists for days. NSAIDs (meloxicam) combined with local anesthetic provide superior pain control. The availability of effective pain management makes inadequate analgesia a welfare failure by choice - there is no justification for performing these procedures without appropriate pain relief.
