Includes structural, behavioral, food, and auditory enrichment.
Self-directed aggression in laboratory macaques is commonly considered an abnormal behavioral pattern signaling psychological disturbance, whether it is in the form of self-injurious behavior (SIB) or is just part of a self-directed threat display (SDD)...
Nest boxes are the only documented effective enrichment devices for laboratory housed owl monkeys (Aotus spp.). Food directed (FD) and non-food directed (NFD) enrichment items were presented to owl monkeys housed as singles, pairs, or...
Different factors can influence the behavioural needs of captive marmosets, and therefore the effectiveness of a particular enrichment
Two enrichment techniques were devised with the aim of reducing stress and improving welfare for captive lion-tailed macaques in an Indian zoo. In Study A, a log, cotton ropes and a feeding basket were added...
Enrichment has been known to increase the well being and species typical behavior of captive animals. While much research has been done on the effectiveness of enrichment or captive monkeys and apes, research on enrichment...
The report sets out how to provide: optimal enclosure characteristicsand size; social housing; solid flooring and substrate; raised areas; refuges; gnawing objects and dietary enrichment; positive interaction with humans; toys and objects to manipulate; for...
Animals in captivity may show undesirable behaviour when they are not sufficiently challenged, making it essential for their well-being to provide daily enrichment to zoo animals. Primates need a regular replacement with novel enrichment objects...
For many animals in nature, foraging is simply a matter of traveling and discovering available food. It provides both physical exercise and mental stimulation, often consuming much of an animal’s time. Replicating this in a...
Behavioral observations were conducted as an ongoing program of monitoring psychological well-being of chimpanzees involved in IACUC-approved preventive medicine studies. The chimpanzees were housed in a facility that provided a variety of enrichment objects, climbing...
Manipulable objects are often provided to laboratory macaques as environmental enrichment, but exposure to objects is widely believed to result in rapid habituation. Consequently, much effort is made to ensure enrichment objects are novel. Here...
