Dehorning cattle causes significant pain and stress, but genetic selection for naturally hornless cattle offers a welfare-positive long-term solution.
Cattle dehorning causes acute pain that is well-documented by behavioral and physiological measures. Animals show pain responses during the procedure and for extended periods afterward when performed without analgesia. Despite the availability of effective local anesthesia and post-procedure pain relief, many operations still perform dehorning without adequate analgesia. The procedure is done because horned cattle can injure each other and handlers, and facilities designed for horned cattle are more expensive - there are practical reasons for the practice. However, the most welfare-positive long-term solution is breeding polled cattle that are naturally hornless. This eliminates the need for dehorning entirely and represents a meaningful welfare improvement achievable through genetic selection without requiring continuous pain management interventions.
