Behavioral responses of captive maned wolves to olfactory enrichment: a preliminary study
Contenido principal del artículo
Resumen
Environmental enrichment is a technique that increases animal welfare. The behavior of maned wolves when exposed to four odors hidden outside the enclosure was investigated. Using the focal animal method and recording all occurrences, their behavior was analyzed for five minutes in each baseline phase (Basal), during exposure (Exp), and after withdrawal of the stimulus (Pos). Behavioral responses were categorized as positive (P+), negative (N-), and other (Ot). The average P+ increased significantly (p < .05) from the Basal to the Exp, but it was not statistically different (p = .6) between the Basal and the Pos. Neither N- nor Ot changed statistically in any of the phases (p > .5). The methodology we used with olfactory stimuli was efficient, seeming to increase the well-being of the maned wolves.
