Curiosity and exploratory behavior in farm animals indicates positive affective states and is increasingly recognized as a welfare indicator alongside traditional deficit-based measures.
Curiosity and exploratory behavior in farm animals serve as powerful, observable indicators of positive affective states. Animals that investigate their environment actively are animals who feel safe enough and comfortable enough to allocate behavioral effort to exploration — a luxury not available to animals experiencing fear, pain, or significant deprivation. Enrichment programs that maintain novelty specifically to sustain exploratory behavior — rotating objects, introducing new materials, varying the environment — are providing genuine welfare benefit by enabling a positive behavioral state. Incorporating exploration observation into routine welfare assessment transforms it from deficit detection to welfare quality evaluation.
