Abstract: Enrichment is a technique to improve physical, psychological and social environment for captive animals. Enrichment efficiency is considered if it stimulates natural behaviours, reduces harmful effects of captivity such as stress and eliminates or reduces abnormal behaviours. Therefore, efficiency can be measured by behaviours analysis. This project aims to identify behavioural of three types of enrichment (musical, environmental and feeding) in a group of 8 mandrills (Mandrillus sphinx) at the Granby Zoo. Considering that behaviour and animal stress can be influenced by the presence of visitors, this project was conduct in fall (no visitors) and summer (with visitors), to induce the effects of human presence. The group was exposed to each type of enrichment over a period of 5 consecutive days. Enrichment was repeated twice for each season. We search primarily to study the effect of each enrichment and the presence of visitors on specific behaviours (stereotypy, agonistic behaviours and human-mandrill interactions), time budget and hierarchy stability with videos (focal or group) and observations. Significant and variable effects according to enrichment were quantified for these behaviours and time budget, to propose different strategies for implementation of these enrichments according to purpose.
