Behavioral effects of enrichment on singly-housed, yearling rhesus monkeys: An analysis including three enrichment conditions and a control group

Rhesus yearlings that received a three-phase, nonsocial, environmental enrichment program during a year of single caging, spent more time playing and less time self-grooming than did control subjects, but abnormal behaviors were not affected.Abstracts of this work have been published...

Primates and coconut halves

Mashed food was pressed into the inside of coconut shell halves and hung almost out of reach. This worked very well for the lemurs. It lengthened their feeding time and made them work for their food. No data are included...

Forage feeder box for single animal cages

Standard feeder with small access holes rather than one big access hole. Time spent foraging during the first hour after biscuit distribution increased from 51 seconds when 40 biscuits were presented in the standard feeder [one large access hole] to...

The use of feeding board as an environmental enrichment device for tufted capuchin monkeys (Cebus apella)

Results show that the feeding board [on which seeds were scattered] were almost always in use [during 30-minute observations]. ... There was no evidence that the position in which the feeding board was placed [high vs low] influenced its use...

An alternative to woodchip as a foraging substrate for tufted capuchin monkeys (Cebus apella)

Our laboratory, a short time after the introduction of woodchip, became infested with domestic mice. ... We decided to adequate the original idea changing woodchip with argilla espansa ... a material that is used in gardening to improve the permeability...

Environmental enhancement for laboratory-housed squirrel monkeys: Fifteen-year retrospective analysis of procedures

The squirrel monkeys are housed in runs that allow them to travel from one cage to another. This allows for large (40 to 60 monkeys) multi-male, multi-female groups similar to those found in the wild. Each run is covered with...

Restraint methods of laboratory non-human primates: A critical review

Published information provides scientific evidence that traditional, involuntary restraint techniques of research non-human primates are intrinsically a source of distress resulting from fear. It has been documented that common methods of enforced restraint result in significantly increased adrenal activity as...

Social housing of previously single-caged macaques: What are the options and the risks? Animal Welfare 4(4), 307-328

A review of the scientific literature gives evidence that transferring previously single-caged adult macaques to permanent compatible pair-housing arrangements (isosexual pairs, adult/infant pairs) is associated with less risk of injury and morbidity than transferring them to permanent group-housing arrangements. Juvenile...
