Polled genetics — natural hornlessness — offer a long-term solution to the dehorning welfare problem, with adoption accelerating through precision breeding.
The dehorning welfare problem has a genetic solution that is technically available but only partially implemented. Polled (naturally hornless) genetics eliminate the need for dehorning entirely, removing a significant repeated welfare cost from the cattle production cycle. Traditional breeding for polled traits is feasible but slow in dairy breeds. Precision breeding using gene editing offers a faster path to polled genetics, with edited bulls now disseminated in some dairy systems. Consumer acceptance of gene-edited livestock products and regulatory frameworks are factors in adoption. The welfare case for accelerating polled genetics adoption is compelling — it replaces a recurring painful procedure with a one-time genetic modification.
