Genomic selection is transforming cattle breeding, enabling selection for disease resistance, temperament, and welfare-relevant traits alongside production performance. Understanding how breeding tools can be applied to welfare outcomes offers new possibilities for systemic welfare improvement.
Selective breeding is among the most powerful tools available for systemic welfare improvement because genetic changes persist across all subsequent generations without requiring ongoing management intervention. Breeding for mastitis resistance reduces the incidence of one of the most common and painful dairy diseases. Breeding for lower lameness susceptibility reduces the most prevalent welfare problem in the sector. Breeding for calmer temperament improves welfare during handling and reduces injury to both animals and handlers. The welfare opportunity in genomic selection is substantial, but it requires welfare traits to be explicitly valued in selection indices, which in turn requires welfare researchers and animal breeders to work in partnership. Consumer demand for welfare-certified products provides the market signal that justifies inclusion of welfare traits in commercial breeding goals.
