Compassionate conservation principles - all individuals matter, do no harm, and peaceful coexistence - offer an ethical framework that complements utilitarian welfare science for pig welfare advocacy.
Compassionate conservation principles applied to pig farming challenge some accepted practices that harm individuals for herd-level benefit. Tail docking harms individual piglets to prevent tail biting in the group; CO2 stunning causes aversive individual experience to enable efficient group processing. These tensions reveal the welfare implications of systems-level solutions to individual welfare problems and suggest alternative approaches worth exploring.
