Abnormal/Problematic Behavior

Utilization of a sensory diet approach for enrichment and mitigation of abnormal behaviors in captive chimpanzees (Pan troglodytes)

Treatment consisted of stimulation of the tactile senses through use of various paper media, a combing/brushing schedule and muscle pressure techniques. A reduction in the rate of coprophagive events was observed.

Orangutan Species Survival Plan Husbandry Manual: Behavioral Biology

Abnormal behaviors occurring in some captive orangutans include lack of maternal skills, stereotypic behaviors, atypical sexual behavior and hyper-aggressiveness. Changes in social groupings, improved housing, behavioral enrichment and positive reinforcement training are known to alleviate some of these undesirable behaviors.

Abnormal behavior in a captive chimpanzee colony

The purpose of this study was to link abnormal behaviors often expressed by chimpanzees living in captive environments to factors related to their care and housing. Individuals who had spent more time with their mothers had less abnormal behavior. Access...

Effect of feed and environmental enrichment on development of stereotypic wire-gnawing in laboratory mice

Enrichment significantly reduced stereotypic wire-gnawing in pair-housed male mice by 40%, presumably as a consequence of the cover provided by the cardboard tubes. This is substantiated by observations that the tubes were used as a place to retreat upon disturbance...

Cage toys reduce abnormal behavior in individually housed pigtail macaques

Providing multiple manipulable toys as enrichment for [single-caged] pigtail macaques was effective in reducing abnormal behavior during 30- min observation session. The use of the toys was reduced over time. The Kong toy was used most consistently.

Risk factors for self-injurious behavior in captive rhesus monkeys (Macaca mulatta)

Research has shown that approximately 10% of captive, individually housed monkeys have had some veterinary record of self-injurious behavior within their life-time. The incidence of self-biting was 14% [!] in a test colony of 188 male individually housed rhesus macaques....

We have experienced limited success in reducing...
