Dehorning causes significant acute and chronic pain in cattle. Pain management protocols and genetic polling alternatives can dramatically reduce the welfare burden of this widespread practice.
Cattle dehorning causes acute, significant pain that is often inadequately managed in commercial practice. The procedure involves destruction of developing horn tissue in calves or removal of mature horns in adult cattle, both of which are painful and associated with measurable behavioral and physiological stress responses. The most welfare-positive long-term solution is the elimination of horns through genetic selection for polled animals — a strategy that is increasingly feasible as polled genetics become more widely available in high-merit breeding populations. Where dehorning continues as a management necessity, the welfare minimum is local anesthesia combined with NSAID analgesia, a combination that substantially reduces the duration and intensity of pain without significant cost or management burden.
