The significant increase of serum cortisol concentration associated with involuntary manual or mechanical restraint during venipuncture was absent in females who were trained to voluntarily cooperate during the procedure in the homecage. The present findings...
The area covered by the floor was 3 times larger than that covered by elevated structures; nonetheless the animals were located significantly more often (89.8% of 108 scan samples) on elevated structures than on the...
A simple training protocol is described which ensures that [most] caged animals readily enter a transport cage.
The sequence in which 14 laboratory rhesus macaques left their home enclosure during a routine catching procedure was recorded on 30 occasions during 6 weeks. The animals were trained to voluntarily exit one by one...
Six adult female stumptailed macaques (Macaca aretoides) were trained within a two week period to actively co-operate during in-homecage venipuncture rather than in a restraint apparatus away from the homecage. The training was based on...
Compatible companionship has a therapeutic effect on behavioral disorders, providing long- term stimulation of a great variety of species-typical social behavior patterns. Inanimate objects have little impact on behavioral disorders, but some of them provide...
Simple technical improvements of three common deficiencies of macaque cages are described: a) dark lower row cages, b) inaccessibility of vertical space, c) lack of privacy.
The environmental enrichment program of the Caribbean Primate Research Center is guided by an evolutionary and ecological perspective. The evolutionary perspective suggests that primates should be housed in enclosures that provide a social and physical...
New techniques were developed to avoid the manual transfer - and the associated health hazard - of caged macaques during handling procedures.
A semi-natural habitat that was designed to house a group of squirrel monkeys is described. Animals maintained in this environment were healthy, and none of the animals exhibited locomotor stereotypies. This facility was easier and...
