While strictly using positive reinforcement and applying patient gentle-firmness, most macaques can be trained to cooperate during the pole-attachment-chairing procedure. Some cannot be trained, because they have problems overcoming their often-legitimate mistrust of humans.
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)...
Nest boxes are the only documented effective enrichment devices for laboratory housed owl monkeys (Aotus spp.). Food directed (FD) and non-food directed (NFD) enrichment items were presented to owl monkeys housed as singles, pairs, or...
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...
Different factors can influence the behavioural needs of captive marmosets, and therefore the effectiveness of a particular enrichment
Males complied with significantly more commands, and overall learned significantly more basic husbandry commands than females. Trainers should expect agonistic responses to increase throughout the training process.
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...
New management strategies for detecting social instabilities and promoting social cohesion are needed to reduce aggression-based morbidity and mortality among captive groups of rhesus macaques (Macaca mulatta). This study determined the utility of social network...
Although our results do not negate the use of cortisol as a welfare indicator in Lemur catta, they do highlight the myriad of behavioural and environmental factors in addition to stress that modify cortisol excretion...
The application of positive reinforcement training (PRT) has increased in zoological, laboratory, and research settings in recent years, however there is little literature pertaining to the development and implementation of such programs. Over the past...
