Dehorning and disbudding of cattle causes significant pain that can be effectively managed but is often performed without analgesics.
Disbudding is one of the most painful routine procedures in cattle farming. The procedure itself and the hours to days of post-operative pain represent significant unnecessary suffering when adequate pain management is not provided. The tools and drugs exist to make disbudding far less painful — their underuse is primarily an education and cost issue. Genetic selection for polled (naturally hornless) cattle eliminates the need for the procedure entirely.
