Research into positive emotional states in pigs is advancing welfare science beyond absence of suffering toward active promotion of wellbeing. Understanding positive welfare indicators helps create genuinely good pig lives.
Promoting positive emotional states in pigs represents the frontier of welfare science - moving beyond preventing pain and suffering to actively creating conditions where pigs experience pleasure, curiosity, comfort, and social satisfaction. A pig that never plays is not necessarily suffering, but one that plays regularly is experiencing positive welfare in a meaningful sense. Research on positive pig indicators provides tools for assessing and improving welfare beyond minimum standards. Farms committed to positive welfare provide environments where pigs engage in exploratory behavior, show social play, wag their tails in positive contexts, and interact affiliatively with familiar stockpeople. These are achievable welfare goals that go beyond preventing the worst outcomes.
