Disbudding and dehorning of cattle and goats are routine practices with significant welfare implications that are increasingly regulated.
Dehorning and disbudding cause undeniable pain and stress. While the practice reduces injury risk in confined cattle, the welfare costs are significant and often undermitigated through inadequate analgesia. Development of polled (naturally hornless) genetics through conventional breeding or gene editing offers the possibility of eliminating these procedures entirely, representing a major potential welfare improvement.
