Pig Positive Welfare Indicators Field

Field-validated positive welfare indicators for pigs go beyond absence of disease to assess whether pigs are experiencing positive states, providing a more comprehensive welfare picture.

Key Facts

Positive welfare indicators for pigs include play behaviour, exploratory nose rooting, and prosocial contact
Tail posture in pigs correlates with affective state - relaxed tail indicates positive state, tucked tail indicates negative
Social play including jaw sparring and chasing indicates absence of fear and positive emotional state
Nest-building behaviour in sows indicates motivated, positive engagement with environment
Positive human-animal relationship is indicated by voluntary approach behaviour in pigs
Quantitative behaviour assessment (QBA) allows whole-group positive welfare scoring by trained observers
Incorporating positive welfare indicators in farm audits provides a more nuanced picture than clinical observations alone

Welfare Considerations

Positive welfare indicators transform welfare assessment from detecting suffering to assessing flourishing. A farm where pigs show regular play, relaxed tail posture, and voluntary human approach is genuinely different - better for the pigs - than one where these indicators are absent even if clinical disease rates are similar. Building positive welfare indicator monitoring into routine practice represents the next generation of farm welfare assessment.
