Fluoxetine dose finding study for treatment of self-injurious behavior in Macaca mulatta

Based on clinical efficacy in the short-term treatment of self-injurious behavior in macaques, we performed a dose-finding study to establish optimal doses of fluoxetine (selective serotonin reuptake inhibitor). The subjects were 11 male (aged 7 – 15 years) rhesus macaques...

Alopecia and overgrooming in laboratory monkeys vary by species but not sex, suggesting a different etiology than self-biting

Alopecia in laboratory monkeys can result from overgrooming (OG), medical conditions, or hormonal variation. Because hair loss is visible, disproportionate intervention may be expected relative to other indicators of potentially compromised well-being. Two analyses (α=0.05) suggest that alopecia and overgrooming...

Why and how should we use environmental enrichment to tackle stereotypic behaviour?

This paper summarises recent findings on the causation of stereotypic behaviours and other abnormal repetitive behaviours (ARBs) in captive animals: primarily motivational frustration and/or brain dysfunction, with possible contributory roles also being played by habit-formation and ‘coping' effects. We then...

A note on enrichment for captive lion-tailed macaques (Macaca silenus)

Two enrichment techniques were devised with the aim of reducing stress and improving welfare for captive lion-tailed macaques in an Indian zoo. In Study A, a log, cotton ropes and a feeding basket were added to the enclosures in different...

The expression of self-injurious behavior in Macaca mulatta: prevalence, risk factors, and context

Self-injurious behavior (SIB) such as self-biting and self-wounding has been observed in a small, but persistent, percentage of captive nonhuman primates. Although biting often looks severe, not all self-biters wound themselves. Risk factors for SIB in rhesus macaques were investigated...

Incorporation of enrichment objects in threat displays by laboratory rhesus macaques (Macaca mulatta)

Self-directed aggression in laboratory macaques is commonly considered an abnormal behavioral pattern signaling psychological disturbance, whether it is in the form of self-injurious behavior (SIB) or is just part of a self-directed threat display (SDD). Objects such as Kong® toys...

Chapter 3. Maladaptive behaviors

Animals kept in legally minimum-sized, unstructured enclosures very often exhibit stereotypical behaviors. Traditionally, these repetitive movement patterns without obvious goals or functions are categorized as abnormal. A healthy animal kept in a small, barren enclosure has little choice of expressing...

Foraging ?enrichment? as treatment for pterotillomania

This study was performed to determine whether foraging enrichment reduces self-directed psychogenic feather picking (pterotillomania) in parrots. A positive correlation between increased foraging time and improvement of feather score was hypothesised. Eighteen pterotillomanic African grey parrots (Psittacus erithacus) were randomly...
