  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.

  Environmental enrichment (EE) 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 < 0.05) from the Basal to the Exp, but it was not statistically different (P = 0.60) between the Basal and the Pos. Neither N- nor Ot changed statistically in any of the phases (P > 0.5). Maned wolves appeared to be sensitive to this EE with the olfactory stimuli used during the period of olfactory stimulation. The method used is practical, safe, and flexible, and can be useful in sensory enrichment programs.

  O enriquecimento ambiental (EE) é uma técnica que aumenta o bem-estar animal. O comportamento dos lobos guará quando expostos a quatro odores escondidos fora do recinto foi investigado. Utilizando o método do animal focal e registrando todas as ocorrências, seu comportamento foi analisado por cinco minutos em cada fase da linha de base (Basal), durante a exposição (Exp) e após a retirada do estímulo (Pos). As respostas comportamentais foram categorizadas como positivas (P +), negativas (N-) e outras (Ot). O P + médio aumentou significativamente (P <0,05) do Basal para o Exp, mas não foi estatisticamente diferente (P = 0,60) entre o Basal e o Pos. Nem N- nem Ot mudaram estatisticamente em nenhuma das fases (P> 0,5). Os lobos guará pareciam ser sensíveis a este EE com os estímulos olfativos usados durante o período de estimulação olfativa. O método usado é prático, seguro e flexível e pode ser útil em programas de enriquecimento sensorial.
