Includes stereotypies, self-injurious behavior, hair pulling (alopecia), barbering, feather pecking, tail biting, etc.
Severe feather pecking, a potentially stereotypic behaviour in chickens (Gallus gallus), can be reduced by providing enrichment. However, there is little comparative information available on the effectiveness of different types of enrichment. Providing forages to...
The combination of mouse igloos and running wheels proved to be highly effective in reducing flipping, circling, and jumping.
The experiment aimed to investigate the effect of type of rooting material and space allowance on explorative and abnormal behaviour in growing pigs. Thirty-six pens with partly slatted concrete floor were allocated to one of...
Stereotyped motor behaviors are a common consequence of environmental restriction in a wide variety of species. Although environmental enrichment has been shown to substantially reduce stereotypy levels, the various components of enrichment have not been...
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...
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...
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...
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...
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...
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...
