Hot-iron branding causes significant acute pain and is used for permanent cattle identification despite less painful alternatives being available. Welfare considerations are driving debate about branding practices.
Hot-iron branding is among the most clearly painful routine cattle procedures, causing third-degree burns and demonstrable behavioral pain responses. The welfare justification for hot-iron branding is weakened by the availability of alternatives including freeze branding, RFID identification, and microchipping. Transitioning to less painful identification methods represents a meaningful welfare improvement without loss of management functionality.
