Effects of environmental enrichment on behavioral expression of pumas (Puma concolor) under human care





The maintenance of pumas under human care imposes different conditions from those found in the natural environment, which may result in stress and impaired welfare. The objective was to evaluate the effects of environmental enrichment on the welfare of four jaguar specimens (Puma concolor), kept under human care. The enrichment techniques addressed were food, sensory, and mixed (physical-cognitive) enrichment. The research was divided into three phases: Phase 1, pre-enrichment; Phase 2, application of enrichment; and Phase 3, post-enrichment. The observation of the activities was performed using the focal animal method, and the behaviors were recorded to compose an ethogram. The sampling effort totaled 96 hours, with a 24-hour observation time for each specimen. During phases 2 and 3, the animals showed increased expression of natural behaviors, increased exploration and interaction with the enclosure, as well as, with other individuals. In addition, the applied activities provided cognitive challenges and reduced the animals' idle time. Although puma 4 showed stereotyped behavior, during the three phases of this study, this individual was healthy and active. Thus, the results demonstrate the beneficial effects of environmental enrichment on the well-being of pumas held in captivity.
