Including temperament, disease resistance, and longevity in cattle breeding goals alongside production traits offers a pathway to improving lifetime welfare across entire cattle populations.
Genetic selection creates lasting and cumulative change in animal populations. Selecting against temperament extremes reduces handling stress and injury risk for both cattle and humans. Selecting for disease resistance reduces lifetime disease burden and associated suffering. Including longevity in breeding goals reduces the proportion of animals culled early due to health failures. These welfare improvements persist and compound across generations. Conversely, failing to include welfare traits in selection means breeding pressure inadvertently moves populations toward greater welfare problems, as has occurred with dairy cow metabolic disease.
