Abnormal/Problematic Behavior

Behavior treatment of alopecia in macaca fascicularis: Comparison of outcomes

Alopecia in captive macaques is assumed to have a behavioral cause; either by over-grooming, or a result of stress. Analysis of behavioral treatments of alopecia remains elusive, yet facilities are accountable for treatment. Retrospective analysis of effects of treatment type...

Hair loss and hypothalamic-pituitary-adrenocortical axis activity in captive rhesus macaques (Macaca mulatta)

Hair loss is a common problem in captive macaque colonies. A potential factor is the possible influence of stressful environments in the development of hair loss. We examined the relationship between hair loss and chronic hypothalamic-pituitary-adrenal (HPA) axis activity by...

Use of an aquarium as a novel enrichment item for singly housed rhesus macaques (Macaca mulatta)

Locomotor stereotypies are behaviors often seen in singly housed rhesus macaques (Macaca mulatta) and are considered to represent a maladaptive response to captive environments. Active and passive enrichment items are commonly used to mitigate these and other abnormal behaviors. Active...

Abnormal behavior and associated risk factors in captive baboons (Papio hamadryas spp

Abnormal behavior, ranging from motor stereotypies to self‐injurious behavior, has been documented in captive nonhuman primates, with risk factors including nursery rearing, single housing, and veterinary procedures. Much of this research has focused on macaque monkeys; less is known about...

Using porches to decrease feces painting in rhesus macaques (Macaca mulatta)

The goal of this project was to evaluate the efficacy of a porch in decreasing feces painting in captive rhesus macaques. The porch is a small extension that is hung on the outside of a monkey's primary home cage. Porches...

Abnormal behaviour in captive sooty mangabeys

The influence of several factors on abnormal behaviour was investigated in 46 singly housed sooty mangabeys (Cercocebus atys) (eight nursery-reared, 38 mother-reared), including self-injurious, self-directed, stereotypic locomotion, and faeces/urine-related behaviours (SIB, SDB, SL, FUR, respectively). An analysis of behavioural assessments...

Stereotypic mice are aggressed by their cage-mates and tend to be poor demonstrators in social learning tasks

Stereotypic behaviours (SBs) are linked with behavioural inflexibility and resemble symptoms of autism, suggesting that stereotypic animals could have autistic-like social impairments. SBs are also common in caged mice. We therefore hypothesised relationships between stereotypic and social behaviours, predicting that...

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...
