Abnormal/Problematic Behavior

Long-term effects of housing and enrichment on affective behavior and responsiveness of Sprague-Dawley rats

Most rodent studies evaluate different caging paradigms over short periods of time, which may not be realistic for typical colony settings. Inappropriate housing may lead to boredom, aggression, stereotypies, and altered metabolism, which in turn may affect experimental responses. In...

Middle-aged mice with enrichment-resistant stereotypic behaviour show reduced motivation for enrichment

For captive animals, living in barren conditions leads to stereotypic behaviour that is hard to alleviate using environmental enrichment. This resistance to enrichment is often explained via mechanisms that decouple abnormal behaviour from current welfare, such as "establishment": a hypothetical...

Monitoring program for the treatment of nonhuman primates with behavioral disorders

Maintaining the psychologic wellbeing of nonhuman primates housed in a laboratory setting is an important aspect in providing the best possible care for these animals. Nonhuman primates kept in captivity can begin to display abnormal behaviors that are not typical...

Stopping self injurious behaviour of a young male chacma baboon (Papio ursinus)

While access to a foraging log had no curative effect on serious self-injurious biting of a single-caged subadult male baboon, transferring the animal to an outdoor section with compatible females in adjacent cages (allowing grooming interactions) resulted in a healing...

A survey of alopecia in group-housed baboons

Although alopecia may arise from a variety of causes, it is often viewed as an indicator of impaired wellbeing, frequently becoming a focus of regulators or facility managers. However, the extent of alopecia in populations of nonhuman primates has not...

Abnormal behaviors in sanctuary chimpanzees (Pan troglodytes)

Chimp Haven has retired 153 chimpanzees, the majority from biomedical research, and abnormal behavior patterns have been reported. Abnormal behaviors are well described in chimpanzees and usually related to early rearing environment, social isolation and sometimes social learning. Data analyzed...

Simply a nest? Effects of different enrichments on stereotypic and anxiety-related behaviour in mice

Improving the home cages of laboratory mice by environmental enrichment has been widely used to reduce cage stereotypies and anxiety-related behaviour in behavioural tests. However, enrichment studies differ substantially in type, complexity and variation of enrichments. Therefore, it is unclear...

The effect of housing and environmental enrichment on stereotyped behavior of adult vervet monkeys (Chlorocebus aethiops)

Little information is available on the response of vervet monkeys to different housing conditions or on the suitability of enrichment devices or methods for vervet monkeys. In this study, the authors evaluated the occurrence of stereotyped behavior in adult vervet...
