The effects of brief manual restraint, prior conditioning and Ketamine sedation on luteinizing hormone and estradiol levels in the female Bolivian squirrel monkey

No effects of conditioning - daily manual restraint suitable for blood drawing - on estrogen levels were observed. Ketamine sedation appeared to elevate estrogen and LH levels in some animals, suggesting complex side effects that may interfere with studies of...

Aggression with mixed age-sex groups of Bolivian squirrel monkeys following single animal introductions and new group formations

When introducing new animals to an established group, the new animals should be unfamiliar with one another so as not to form competing 'teams'. Additions to groups should include enough animals so that aggression from the resident group will be...

Cage design and configuration for an arboreal species of primate

Squirrel monkeys preferred a poly-vinyl-chloride pipe perch (rigid) over rope perches (non-rigid). For an arboreal animal, a higher perch may be perceived as safer. Additional perches decreased the propensity for development of tail ulcers associated with floor contact. With only...

Free-environment rooms as alternative housing for squirrel monkeys

Individual and gang cages were removed from two conventional colony rooms and the monkeys [11 females and 5 males] were simply released into the rooms. ... Immediately following the establishment of these two free-environment rooms, a few monkeys incurred sprains...

A closed colony of squirrel monkeys for laboratory studies

For a behaviourally healthy and hence happy existence the squirrel monkey really requires more space than even our quadruple cage system provided. Pens of the size of our exercise pens would avoid stereotypic locomotor behaviour, especially if provided with a...

Psychological well-being of primates in captivity

Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to “promote their psychological well-being.” Unfortunately, no consensus presently exists in terms...

Polyvinyl chloride piping as perch material for squirrel monkeys

An additional unexpected benefit of the PVC piping has been a decrease in dorsal tail-head abrasions, frequently seen in squirrel monkeys that sit on the stainless steel flooring of standard primate cages.

Two enrichment devices for Saimiri sciureus

Two enrichment devices [suspended chain and rings placed on cage floor] were successfully introduced to singly-caged male squirrel monkeys to increase cage complexity.

Sociophysiology of well-being in nonhuman primates

We have found, for example, that formation of same-sex groups of squirrel monkeys is rarely accompanied by injurious aggression. Once unisexual groups have stabilized, formation of larger heterosexual groups generally proceeds smoothly (p. 347). [Group formation procedure is not described.]...
