Pig Genetic Welfare and Breed Selection

Genetic selection in pigs has prioritised productivity at the expense of welfare-relevant traits, but selection for welfare is growing.

Key Facts

Modern commercial pig genetics produce faster-growing pigs with higher muscle yield
Selection for leanness has reduced fat cover, increasing cold sensitivity in neonates
Maternal behaviour, leg strength, and disease resistance are welfare-relevant traits
Some breeding companies now include welfare metrics in selection indices
Genomic selection allows rapid genetic progress in welfare traits if prioritised

Welfare Considerations

Genetic selection is a powerful but slow lever for welfare improvement. Traits that have been eroded by generations of production-focused selection - such as maternal ability, disease resistance, and robustness - can be restored through deliberate welfare-focused breeding programmes.

What You Can Do

Support organisations advocating for welfare-inclusive breeding indices
Choose pork from producers who specify breed welfare considerations
Advocate for regulatory requirements for welfare trait inclusion in genetic selection
