Abnormal/Problematic Behavior

Self-directed biting in male rhesus monkeys (Macaca mulatta) with self-injurious behavior (SIB) increases following acute treatment with the anxiogenic drug FG7142

A small percentage of captive macaques spontaneously exhibit self-injurious behavior (SIB), mostly in the form of self-directed biting. Several risk factors have been identified in the etiology of SIB in monkeys, including exposure to early life stressors. We hypothesize that...

Assessment of efficacy of three types of foraging enrichment in rhesus macaques (Macaca mulatta)

Rhesus macaques housed indoors in captivity commonly display abnormal behaviors that are rarely seen in their wild counterparts. These behaviors include stereotypic behaviors and self-abuse. These behaviors are often seen as signs of poor welfare, due to stressors in the...

Developing a reliable laboratory primate alopecia scoring system for interfacility collaboration and on-line training

Of the potential flags of impaired well-being in laboratory primates, alopecia has received particular regulatory focus, making it a top priority for behavioral managers. Consensus on a reliable alopecia scoring system used by multiple facilities can better determine prevalence and...

Rate of self-injurious behavior in buspirone-treated rhesus macaques (Macaca mulatta) across different levels of human activity in the environment

This study examined the effectiveness of an anxiolytic drug, buspirone, in rhesus macaques with a history of self-injurious behavior. ... However, self-biting was more prevalent during periods of high activity. Treatment with buspirone was not associated with decreased time in...

Floating limb behaviors and self-biting are associated in laboratory monkeys

Early descriptions of floating limb behaviors in monkeys were associated with isolation rearing, a practice that ended more than two decades ago. The present authors named various forms of behaviors in which a leg is elevated for no apparent reason:...

Frustration and perseveration in stereotypic captive animals: Is a taste of enrichment worse than none at all?

Stereotypic behaviours are common in animals in impoverished housing, arising from two complementary processes: (1) thwarted attempts to perform motivated behaviours; (2) forebrain dysfunction impeding normal behavioural inhibition. When enriched animals are moved to impoverished housing, they are sometimes protected...

The effect of type of rooting material and space allowance on exploration and abnormal behaviour in growing pigs

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 four treatments: (1) low space...

The effects of four types of enrichment on feather-pecking behaviour in laying hens housed in barren environments

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 birds is likely to decrease...

Effects of access to voluntary wheel running on the development of stereotypy

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 evaluated independently to determine which...
