Abnormal/Problematic Behavior

Effects of environmental enrichment on nonsocial and abnormal behavior of captive lowland gorillas (Gorilla gorilla gorilla)

The use of straw as bedding material appears to have a positive effect on both specific nonsocial [feeding/foraging] and abnormal behavior [coprophagy, regurgitation].

Provision of straw as a foraging substrate reduces the development of chain and bar manipulation in food restricted sows

Abnormally high levels of chain and bar manipulation can be prevented by providing straw which apparently acts as a foraging substrate for food-restricted sows.

Effects of enriched food acquisition on activity budgets of two tamarin species at Adelaide Zoo

Simple bamboo pipe feeder is described and tested in group-housed animals. The aim of the study was to [successfully] increase foraging time with an increasing number of feeding devices [brawn bowl, bamboo pipe]. ... Prior to the study large amounts...

Limitations on the effectiveness of environmental improvement in reducing stereotypic behaviour in bank voles (Clethrionomys glareolus)

Young voles performed stereotypic behaviour in the enriched cage, so stereotypies were harder to disrupt through environmental enrichment in older voles.

Environmental enrichment: does it reduce barbering in mice?

One of the problems in maintaining group-housed mice is barbering one or more mice chewing (barbering) the fur and whiskers of other mice. A group of 300 mice of both sexes, which are being studied over their lifetime, were housed...

The application, use, and effects of training and enrichment variables with Japanese snow macaques (Macaca fuscata) at the Central Park Wildlife Center

A training protocol is briefly described which allows the keepers through vocal and visual cues to herd the animals to a holding area. Training sessions were deterring stereotypic and abnormal behaviour - such as excessive grooming and fur-pulling. A feeding...

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.
