Primates, as a group, offer great opportunities for positive reinforcement work.
Reinhardt, V. 1992. Are rhesus macaques really so aggressive? International Zoo News 39(1), 14-19.
Several years of experience with pair housing of previously single-caged adult rhesus macaques and venipuncture in the home cage of cooperative, non-resisting animals lead the author to conclude that rhesus macaques are not as aggressive...
Reinhardt, V. 1992. Environmental enhancement plan for previously single-caged adult rhesus macaques (Macaca mulatta). Anima
To promote the well-being of previously single-caged adult (older than 5 years) rhesus macaques (Macaca mulatta) and the quality of research done with them, the following environmental enhancement plan has been developed and implemented at...
Reinhardt, V. 1992. Improved handling of experimental rhesus monkeys. In: The Inevitable Bond. Examining Scientist-Animal Interactions. Davis, H., Balfour, A. D. (eds), 171-177. Cambridge University Press, Cambridge, UK.
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...
Reinhardt, V. 1992. Space utilization by captive rhesus macaques. Animal Technology 43, 11-17.
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...
Reinhardt, V. 1992. Transport-cage training of caged rhesus macaques. Animal Technology 43, 57-61.
A simple training protocol is described which ensures that [most] caged animals readily enter a transport cage.
Reinhardt, V. 1992. Voluntary progression order in captive rhesus macaques. Zoo Biology 11,(1) 61-66.
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...
Reinhardt, V., Cowley, D. 1992. In-homecage blood collection from conscious stumptailed macaques. Animal Welfare 1(4), 249-255.
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...
Reinhardt, V., Reinhardt, A. 1992. Quantitatively tested environmental enrichment options for singly caged nonhuman primates:
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...
Reinhardt, V., Zweifel, D., Pape, D. 1992. Improving the microenvironment of caged laboratory macaques. Animal Technology 43,
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.
