The use of guanfacine to control self-injurious behavior in nonhuman primates

Self-injurious behavior (SIB) affects up to 10% of laboratory-housed nonhuman primates. ... Guanfacine therapy provides an effective psychological-stabilizing tool which alleviates self-biting, and provides time to assess and address external stressors and triggers.

Techniques for collecting saliva from awake, unrestrained, adult monkeys for cortisol assay

Our laboratory has developed two methods [not outlined in this abstract] for collecting saliva [e.g., for cortisol determination] from adult rhesus monkeys: a 'screen' method, which involves licking screen-covered gauze, and a 'pole' method, which involves sucking and chewing on...

Environmental enrichment: Evaluation of the behavioural modifications in the presence of four kinds of litter in Cebus capucinus

A captive group of white-faced capuchins, Cebus capucinus, was presented with four deep litters in simultaneous choice (or preference) tests. A floor covering of ground corn cob, woodchips, wood wool or peat was presented once in each quarter of the...

A review of nutritional and motivational factors contributing to the performance of regurgitation and reingestion in captive lowland gorillas (Gorilla gorilla gorilla)

Regurgitation and reingestion (R/R) is a common phenomenon in captive lowland gorillas (Gorilla gorilla gorilla), but it has never been reported in wild populations. Although changes in diet have been shown to reduce the behavior, little is known about the...

The timing of mother-infant separation and its effect on postpartum estrus and subsequent conception in captive baboons

Forced infant weaning at an early age is often practiced by primate breeding facilities to initiate the onset of postpartum estrus and, consequently, maximize reproduction. ... There was [indeed] a significant correlation between age at removal and duration until postpartum...
