Genomic testing in cattle enables faster selection for health and welfare traits, accelerating population-level welfare improvements through precision breeding.
Genomic testing provides welfare-relevant breeding information at unprecedented accuracy and speed. Health traits including mastitis resistance, lameness susceptibility, and longevity can be selected for with more precision than traditional estimated breeding values. The shortened generation interval means welfare improvements can permeate populations faster. Farmer adoption of health trait weighting in sire selection decisions directly translates genomic welfare science into farm welfare outcomes. Welfare-focused genomic selection represents a long-term investment with compounding returns as welfare-improved genetics become predominant in national herds.
