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...
An olfactory enrichment technique is described.
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...
Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or...
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...
There is a general consensus among those studying the welfare of captive primates that social housing is the most effective means for promoting psychological well-being. It is well established that socially-housed rhesus macaques (Macaca mulatta)...
Lean management-based visual tools have been used to improve the quality of animal care associated with a complex research study involving immune-compromised cynomolgus monkeys (M. fascicularis) in various postsurgical recovery states. In order to effectively...
