Impact of a privacy panel on the behavior of caged female rhesus monkeys living in pairs

Thirty paired female rhesus monkeys were tested in a control situation when companions had no privacy, and in an experimental situation when they were offered the option to move behind a panel and be alone. Paired partners spent significantly more...

An alternative method for primate perch installation

Modification of squeeze cages is described allowing the installation of a perch that does not interfere with the normal operation of the cage.

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...
