Environmental Enrichment

A comparative study of a group of colobus monkeys Colobus guereza matschiei before and after enrichment of their captive environment

The effect of the enrichment devices [barklitter, branches, basket filled with 'goodies', etc.] applied on the colobus exhibit could be seen both in a totally higher score for 'activity' [29.3%], and a higher amount of social interactions [16.5%].

Assessing the welfare implications of environmental enrichment

The success of environmental enrichment will depend on the ability of staff to interpret the animal's state of mind before and after the change. This is the role, first, of the care giver who knows and understands the animal and...
