Although alopecia may arise from a variety of causes, it is often viewed as an indicator of impaired wellbeing, frequently becoming a focus of regulators or facility managers. However, the extent of alopecia in populations...
The discussion was started by the following questions: "Is the squeeze-back mechanism more or less stressful than the pole and collar system for removing a macaque from his cage for an IM (intramuscular) injection?" and...
In order to prevent physical and psychological deterioration in older animals, it is important to apply the same principles of environmental enrichment and housing as are applied to younger animals. As we have discussed above...
At the Oregon National Primate Research Center, we train animals to enter transfer boxes using positive reinforcement training (PRT), a type of training in which the trainer reinforces desired behaviors (such asentering the transfer box)...
The [ice] blocks provide a stimulating foraging experience for the NHPs. The blocks last up to an hour fully melting; however, most NHPs have them broken apart and are eating them within 15 minutes. Some...
Animal care for nonhuman primates (NHPs) in biomedical facilities has undergone major changes in the past few decades. Today, most primate facilities have dedicated and highly trained animal care technicians who go to great efforts...
In the wild, many primates consume gums exuded from trees, and many species are gum specialists. In spite of this, few data exist concerning gum feeding in captivity. Using a web-based survey of 46 zoos...
At the Yerkes National Primate Center we have developed a system for behavioral assessment that includes these elements: frequent observation of behavior for all primates with a check sheet-type record; a quantitative system for recording...
The racks provide four different levels of horizontal bars where manipulanda can be hung. .. The racks are positioned in front of a 4-caged housing system. .. The enrichment racks have produced an increase in...
In captive research environments for nonhuman primates (NHP), social housing strategies are often in conflict with protocols designed to minimize disease transmission. This is particularly true in breeding colonies, and is especially relevant when attempting...
