Includes stereotypies, self-injurious behavior, hair pulling (alopecia), barbering, feather pecking, tail biting, etc.
Alopecia in laboratory primates is often regarded as a sign of excessive self-grooming due to social deprivation or insufficient environmental enrichment. The purpose of this study was to examine, in individually housed macaques, the occurrence...
Under animal care situations that conform to compliance standards for environmental enrichment established by the Animal Welfare Act (AWA) and the Guide to the Care and Use of Laboratory Animals, at least 10% of laboratory...
In the present study, high feather pecking (HFP) and low feather pecking (LFP) birds were used to investigate if the lines differ in their willingness to work for food or feathers in the presence of...
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...
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...
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...
Considered signs of decreased welfare--abnormal behaviors such as self-injury and self-abuse among nonhuman primates housed in the laboratory--may put into question the validity and reliability of scientific research using these animals as models. Providing environmental...
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...
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...
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...
