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...
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...
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...
Adriane and Kris just trained eight rhesus monkeys to present their arms in the blood sleeve for blood samples, and it took, on average ... 8 months ... 160 minutes spread out into 40 sessions.
It is well established that grooming underpins sociality in group-living primates, and a number of studies have documented the stress-reducing effects of being groomed. In this study, we quantified grooming behaviour and physiological stress (assessed...
Live, direct observations are often used to collect behavioral data. However, the presence of an observer may affect the behavior of unhabituated subjects. This study was conducted to determine the effect of an observer’s presence...
Manipulable objects are often provided to laboratory macaques as environmental enrichment, but exposure to objects is widely believed to result in rapid habituation. Consequently, much effort is made to ensure enrichment objects are novel. Here...
