The question was asked: “Research protocols sometimes require that compatible macaque pairs be physically separated for a limited time period (e.g., controlled food-intake studies; sample collection from chair-restrained subjects). Obviously – and as documented in...
However, tactile contact can also be provided by means of barred or perforated panels that permit physical interaction but prevent entry into pair-mates' cages. Behavioral outcomesmay differ between these housing configurations and between species. To...
Captive groups of primates often exhibit higher rates of aggression than wild, free-ranging groups. It is important to determine which factors influence aggression in captivity because aggression, particularly intense aggression, can be harmful to animal...
The welfare of zoo animals depends on a combination of physical, social, dietary and other ecological characteristics of the captive setting. We analysed the influence of the transfer of an adult couple of hamadryas baboons...
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...
Primates have a fascination with mirrors. There is much literature available although no previous studies have been carried out to determine the benefits of mirrors for the Common Marmoset (Callithrix jacchus). Initially a six week...
An olfactory enrichment technique is described.
Although the use of wild-born primates in research is banned in some countries, in others it is commonplace. It has been demonstrated that not only do wild-born primates react more strongly to some stressors than...
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...
