Multifunctional cage for macaques housed in pairs or in small groups

Existing double-cage units were modified to provide optimal housing and handling conditions for pair-housed macaques. Perch installation allows normal operation of the squeeze-back; a privacy panel offers optional visual seclusion.

Serum cortisol concentrations of single-housed and isosexually pair-housed adult rhesus macaques

Possible social distress was evaluated in 20 adult rhesus macaques housed in compatible isosexual pairs (5 female pairs, 5 male pairs) for the purpose of social environmental enrichment. Serum cortisol concentrations of paired animals were compared with serum cortisol concentrations...

Avoiding undue cortisol responses to venipuncture in adult male rhesus macaques

Six adult rhesus males were: a) habituated to actively cooperate during venipuncture away from the homecage in a treatment squeeze cage, and b) trained to actively cooperate during venipuncture in the homecage.The magnitude of cortisol increase was significant when the...

Training adult male rhesus monkeys to actively cooperate during in-homecage venipuncture

A training technique is described for ensuring the active cooperation of 10 pair-housed and 5 single-housed adult male rhesus monkeys during in-homecage venipuncture. Mean cumulative training time investment per male was 40 minutes. Once trained, all males cooperated during in-homecage...

A practical assessment of a non-human primate exercise program

In two different heterosexual groups of eight adult capuchins aggressive interactions were absent when the familiarized, carefully preselected single-caged subjects were introduced in a large exercise cage.Rhesus macaques engaged in a serious aggressive interactions in the same situation.

Environmental enrichment for Macaca fascicularis: Effects of shape and substance of manipulable objects

The ring was the most effective shape and the translucent flexible plastic was the most effective substance. Some abnormal self-directed behavioral patterns decreased significantly in the presence of manipulable objects. [Age of animals is not indicated.]

Impaired performance from brief social isolation of rhesus monkeys (Macaca mulatta): A multiple video-task assessment

Both the number and the quality (i.e., speed and accuracy) of responses were significantly compromised in the social isolation condition relative to levels in which the animals were tested together.
