Livestock Welfare Through Genetic Selection

Genetic selection for welfare traits offers a powerful long-term intervention for farm animal welfare. Selecting against health problems, temperament issues, and welfare-compromising traits improves multiple generations.

Key Facts

Genetic selection against bovine respiratory disease susceptibility has achieved measurable reductions in disease incidence
Selection for maternal behavior in sows improves piglet survival and reduces crushing rates significantly
Residual feed intake selection in cattle has been associated with improved temperament as a correlated trait
Keel bone fracture resistance selection in laying hens is being pursued by several breeding companies

Welfare Considerations

Genetic selection for welfare traits complements management improvements by embedding welfare outcomes into animal biology rather than requiring continuous management intervention. Animals genetically selected for disease resistance, calm temperament, and structural health are more resilient across different management systems. The long-term nature of genetic change requires commitment from breeders, producers, and consumers, but the welfare impacts persist across generations.
