Abnormal/Problematic Behavior

Comparison of pig behaviour when given a sequence of enrichment objects or a chain continuously

Tail biting is a major problem in modern pig (Sus scrofa) production and results in a reduction of animal welfare and productive performance. Biting behaviour has been shown to be decreased by the use of enrichment objects. In this study,...

Effect of environmental enrichment after the occurrence of wet bedding created by mice and abnormal fur in mice

In management of laboratory animals, wet bedding created by mice and abnormal fur in mice cause problems on housing, leading to negative effects both on the wellbeing of mice and on the validity of experimental results. Most studies have investigated...

Environmental enrichment reduces the likelihood of alopecia in adult C57BL/6J mice

Barbering (incessant grooming) is an abnormal behavior causing alopecia and commonly affects various strains of laboratory mice, including C57BL/6J. Barbering-induced alopecia is a potential symptom of brain impairment and can indicate a stressful environment. We compared alopecia prevalence and severity...

Individual differences in temperament and behavioral management practices for nonhuman primates

This review will examine how individual differences in temperament might affect, or be affected by, behavioral management practices for captive primates. Measuring temperament may help us predict the outcome of social introductions. It can also predict which animals may be...

Litter size predicts adult stereotypic behavior in female laboratory mice

Stereotypic behaviors are repetitive invariant behaviors that are common in many captive species and potentially indicate compromised welfare and suitability as research subjects. Adult laboratory mice commonly perform stereotypic bar-gnawing, route-tracing, and back-flipping, although great individual variation in frequency occurs....

Platelet activation in the context of stress in self-injurious rhesus macaques

Stress has been associated with adverse hematologic and physiologic consequences, including immunosuppression and an increased risk of cardiac disease. Aberrant platelet activation has been documented in humans exposed to mental stress, and activated platelets, as participants in both immunity and...

Abnormal behavior in captive baboons (Papio hahadryas sp.)

Abnormal behavior in macaque monkeys has been associated with risk factors such as nursery rearing and single housing. However, less is known about the extent of, and risk factors for, abnormal behavior in baboons. The purpose of this study was...

Objective assessment of self-injurious behavior in rhesus macaques and successful treatment with guanfacine

Self-injurious behavior (SIB) occurs sporadically in 5% to 15% of captive nonhuman primates, with over-representation among males and those animals housed in single caging prior to adulthood. Though SIB may manifest as a range of specific behaviors, the most clinically...

Efficacy of 3 types of foraging enrichment for rhesus macaques (Macaca mulatta)

The 3 enrichment devices had different effects on individual expression of stereotypy: supertubes decreased it, shakers increased it, and puzzle balls led to a decrease followed by an increase. We present potential reasons for the changes in stereotypy and postulate...
