The effects of privacy walls on aggression in a captive group of rhesus macaques (Macaca mulatta)

Preliminary results suggest that non-contact aggression (vocalizations, fear grimaces, chases, and threats) is significantly reduced after the introduction of the privacy walls (p

A cart cage for transferring macaques, capuchins, and small dogs

A novel mobile monkey transport cart cage allows ease of handling, safety, secure holding, good visual access to the monkeys, room for large macaques, and ease of assembly, all at a modest cost.

Effects of chair restraint on the strength of the tibia in rhesus monkeys

To determine the effects of the relative inactivity .. we used a non-invasive test to measure bending stiffness, or EI. ... Five monkeys, restrained in chairs for 14 days, showed decreases in EI.

Group-housing subadult male cynomolgus macaques in a pharmaceutical environment

A carefully designed, successful group-formation and group-housing protocol of five 3.5+ years old previously single-caged cynos is described in detail. Not only can the social complexity of the animals' interactions be increased, but also routine tasks can be accomplished with...

Training pair-housed rhesus males to cooperate during blood collection

In many laboratory studies, venipuncture (blood collection) is a routine activity. Some animal care managers assume that blood collection requires single-housing and squeezing (and stressing) the primate subjects. Not true!Here, we show a simple training procedure that is based on...

The impossible housing and handling conditions of monkeys in research laboratories

The prevailing housing and handling conditions of monkeys in research institutions is described. The present situation in primate research laboratories strongly suggests that professional judgment is no guarantee that the inhumane housing and handling conditions of laboratory monkeys will ever...

Effective feeding enrichment for caged and pen-housed macaques at no cost

Using already existing structures of the cage, food puzzles can readily be 'constructed' to entice the animals to work for the retrieval of their daily rations of monkey chow.There are two options of 'constructing' such puzzles.

Ideas of improving living conditions of non-human primates by improving cage design

Refinement in cage design are described that improve personnelsafety and routine husbandry procedures. It is difficult to observe animals in the bottom cages due to insufficient lighting. Flashlights can increase visualization in this situation. New cage specifications are designed to...
