Abnormal/Problematic Behavior

Laboratory animal behavior

The study of laboratory animal behavior has increased steadily over the last decade, with expanding emphasis on a variety of commonly used species. In the United States, this trend was initially focused on species for which there was a regulatory...

Use of cuttlebones to reduce the incidence of feather pecking in chickens

Feather pecking is a maladaptive behavior where chickens (and other poultry species) peck the feathers of conspecifics and damage the plumage and frequently the skin. It is one of the most common behavioral problems in chickens today and can lead...

Crowding increases salivary cortisol but not self-directed behavior in captive baboons

Reduced space can lead to crowding in social animals. Crowding increases the risk of agonistic interactions that, in turn, may require additional physiological defensive coping mechanisms affecting health. To determine the stress induced from increased social density in a group...

Effects of stereotypic behaviour and chronic mild stress on judgement bias in laboratory mice

Cognitive processes are influenced by underlying affective states, and tests of cognitive bias have recently been developed to assess the valence of affective states in animals. These tests are based on the fact that individuals in a negative affective state...

Evaluation of environmental and intrinsic factors that contribute to stereotypic behavior in captive rhesus macaques (Macaca mulatta)

Full body repetitive behaviors, known as motor stereotypic behaviors (MSBs), are one of the most commonly seen abnormal behaviors in captive non-human primates, and are frequently used as a behavioral measure of well-being. The main goal of this paper was...
