Lower-row caging in a two-tiered housing system does not affect the behaviour of young, singly housed rhesus macaques

It has been suggested that housing of laboratory primates in two-tiered racks adversely affects the psychological well-being of those primates housed on the lower row. Excessive darkness and its consequences are among the factors suggested to account for the supposed...

Chair restraint for squirrel monkeys

Nonhuman primates, no matter how small, can be a danger to handlers. Restraint is necessary to allow sample collection, drug administration or physical examination. Commonly used procedures include moveable-back cages, manual restraint and the use of restraint chairs. Such procedures...

Exhibit use by great apes as part of a post-occupancy evaluation

All apes [6 chimpanzees and 15 gorillas] used the various strata of the exhibits, but there were species differences in exhibit use. Four of the six chimps spent most of their time in the highest two meters of the exhibit,...

Self-biting in caged macaques: Cause, effect and treatment

In the United States, there are an estimated 15,000 individually caged macaques. If 10% of these animals exhibit visible injuries resulting from self-biting and another 10% show unnoticed self-biting behavior, then about 3,000 animals (20%) are affected by this gross...
