Includes stereotypies, self-injurious behavior, hair pulling (alopecia), barbering, feather pecking, tail biting, etc.
Positive reinforcement training is an important element of behavioral management programs for nonhuman primates. However, more empirical information is needed to determine whether animals identified for intervention will engage in such training, affecting the amount...
Self-injurious behavior (SIB) presents a serious problem in laboratory macaques that cannot be socially housed for scientific reasons. Pharmaceutical treatments that alter the serotonin (5HT) system have sometimes proven effective in alleviating SIB in both...
Self-injurious behavior (SIB) is a problem of virtually all nonhuman primate research facilities. Its incidence varies between institutions and with the strictness of the criteria that are used. Nevertheless, it is widely agreed that several...
As a way to reduce abnormal behaviors, specifically finger-sucking, hair-pulling, and reingestion/regurgitation, observed in two male gorillas at The ZOO Northwest Florida, a complex enrichment device that was contingent on the gorilla's ability to use...
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)...
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...
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...
At a previous institution we had a cyno who suffered from severe hair pulling. He had removed practically all hair from his body; all that was left was a patch in the middle of his...
Self-injurious behavior (SIB) can result in open wounds, tissue damage, and increased risk of infection. In many cases, increased environmental enrichment is not consistently effective in eliminating this behavior. We report here on the successful...
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...
