Environmental enrichment-related injury in a macaque (Macaca fascicularis): Intestinal linear foreign body

As a result of this incidence [ingested sisal rope pieces leading to multiple ulcerations, perforations, septic peritonitis] sisal rope enrichment devices were immediately removed from all macaque cages in the facility.

The lower row monkey cage: An overlooked variable in biomedical research

A survey of 96 primatological articles revealed that cage location of research monkeys is usually not mentioned (98%), in spite of the fact that the environment of upper- and lower-row housed animals markedly differs in terms of light quality, light...

Rigid plastic balls as environmental enrichment: A novel presentation

At the Primate Foundation of Arizona (PFA), we provide many different types of both destructible and indestructible objects, but seldom provide rigid plastic balls. They are frequently thrown about the enclosure during displays and have damaged the cage mesh. We...

Daily feeding enrichment for laboratory macaques: Inexpensive options

The feeding enrichment options described here are structural elements of the cage, redesigned in such a way that they serve as primary feeders for the daily biscuit ration. Therefore, no extra time is needed to clean them and to bait...

Predictors of social status in cynomolgus monkeys (Macaca fascicularis) after group formation

The purpose of the present study was to determine whether various behavioral and hormonal markers obtained in individually housed monkeys would be predictive of social rank following group housing. Body weight, serum cortisol and testosterone levels, and locomotor activity in...

Pair-formation protocol for adult, previously single-caged macaques: Minimizing risks

This is a systematic method of introducing two adult macaques in a way that minimizes risks - and lets the monkeys have some control over the process.The alternative method of simply introducing unfamiliar animals into one cage is ethically not...

Environmental enrichment for rhesus macaques: A cost-effective exercise cage

A movable exercise cage for rhesus macaques is described. Within our facility, increased visual attentiveness by other animals, decreased self-directed biting and hair picking, and improved food consumption was observed when rhesus macaques were permitted access to an exercise cage...
