Abstract
Abstract In this study, stimulus objects (frozen blood balls, fresh zebra dung, scented squash, and cardboard boxes) were utilized in an enrichment program aimed to increase the diversity of behaviors exhibited by one female and three male tigers (Panthera tigris sumatrae) and two male lions (Panthera leo leo). Three enrichment sessions consisting of pre-enrichment control, enrichment, and post-enrichment trials of 30-min each were conducted over a two-day period. Stimulus objects were present only in the enrichment trials. The enrichment sessions were replicated three times for each stimulus object. Behavioral states, discrete behaviors, and object-directed behaviors were recorded. Behavioral diversity indices (BDIs) for each trial were calculated using the Shannon Diversity Index. The stimulus objects increased behavioral diversity during the enrichment trials compared to the control trials, but this effect did not persist to the post-enrichment trials the following day. The lions benefited the most fro...
