Pain in pigs is systematically undertreated in commercial production; developing pain assessment tools and normalizing analgesic use represents a major welfare improvement opportunity.
Pig pain has historically been massively undertreated in commercial production, with the farming community often minimizing the welfare significance of routine painful procedures. The development of validated pain assessment tools like the Pig Grimace Scale removes the justification of 'we can't tell if they're in pain.' Normalized analgesic use in pig farming is both ethically required and increasingly technically achievable.
