Effects of positive reinforcement training on cortisol, hematology and cardiovascular parameters in cynomolgus macaques (Macaca fascicularis)

Animals assigned to a training program showed lower cortisol levels than control subjects.

Indirect indicator of transport stress in hematological values in newly acquired cynomolgus monkeys

An increase in neutrophil-to-lymphocyte (N/L) ratio with a marked increase in neutrophils and a decrease in lymphocytes was observed on arrival, and the increased N/L ratio returned approximately to the normal level 1 week after arrival. The serum cortisol level...

Alopecia scoring: the quantitative assessment of hair loss in captive macaques

Many captive animals show forms of pelage loss that are absent in wild or free-living conspecifics, which result from grooming or plucking behaviours directed at themselves or at other individuals. For instance, dorsal hair loss in primates such as rhesus...

Assessment of stress in non-human primates: application of the neutrophil activation test

All macaques were group-housed indoors in either a traditional caging system of three linked modules of typical reinforced stainless steel two-tier laboratory cages, or in open-rooms containing either these cages with the fronts removed or no caging at all. ......

Primate popsicles

When the frozen enrichment treats were first provided to our rhesus macaques, they showed a great deal of interest and worked steadily at removing the food from the ice. After several months of using this enrichment, the primates still enjoy...

Effects of isosexual pair-housing on biomedical implants and study participation in male macaques

Social housing has been shown to contribute to the psychological well-being and physical health of captive primates, and this factor has led to United States Department of Agriculture guidelines requiring facilities to address the social needs of primate species known...

Implementing housing refinements in a rhesus macaque colony

Keeping rhesus macaques alone in barren cages and applying forced restraint during blood collection is a distressing experience for the animals. Refinement techniques were, therefore, developed and an attempt made to implement them in a biomedical research facility with 728...

Primate pairing under less than ideal circumstances

Of the six male cynomolgus monkeys in our group, we were able to create three stable pairs. The animals share food, and although we have had some minor bumps and bruises, there have been no serious injuries. We later reproduced...

Videotape entertainment may facilitate recovery for monkeys in a clinical setting

When introduced to videotapes rhesus monkeys, for the most part, display a degree of visual attentiveness toward videotape programming. Gender and rearing history appear to have little relationship to overall interest in videotapes.
