Herreid, C. F., Schlenker, E. H. 1980. Energetics of mice in stable and unstable social conditions: evidence o
Male mice kept individually have a 15% higher metabolic rate than mice kept in stable same gender pairs.
Lenox, R. H., Kant, G. J., Sessions, G. R. et al. 1980. Specific hormonal and neurochemical responses to different stressors
The neuroendocrine and neurochemical responses of rats to 5 min of cold exposure versus 5 min of forced immobilization were determined and compared. We found that plasma hormones and brain neurochemical systems responded differently to...
Mackay-Sim, A., Laing, D. G. 1980. Discrimination of odours from stressed rats by non-stressed rats. P
Placing a rat into a new cage triggers release of corticosterones. This endocrine response is augmented if the new environment is one in which other rats had previously been subjected to stress.
Mantel, N. 1980. Assessing laboratory evidence for neoplastic activity. Biometics 36, 381-399.
Mortality and tumor incidence in corcinogenesis experiments differ between mice caged in the top vs. bottom of the rack.
Panksepp, J., Herman, B. H., Vilberg, T. et al. 1980. Endogenous opioids and social behavior. Neuroscience and Biobeh
Evidence for the hypothesis that brain-opioids mediate social affect and social attachments is summarized. Opiates and opioids are very effective in reducing social separation-induced distress vocalizations (DVs), in puppies, young guinea pigs and chicks, while...
Boyd, J. 1988. Mice. Humane Innovations and Alternatives in Animal Experimentation 2, 49-50.
Description of an ingenious, simple method to minimize odor, provide species-appropriate nesting opportunities and to facilitate cleaning.
Gray, G. 1988. Guinea pigs. Humane Innovations and Alternatives in Animal Experimentation 2, 48-49.
Initial attempts to provide the animals a covered area for refuge showed that the guinea pigs adopted the shelter very quickly and would dart under cover when startled. ... We soon realized that this was...

The high prevalence of stereotypies in mice kept in standard animal facilities is underscored.
Hirsjarvi, P., Valiaho, T. 1995. Gentled and nonhandled Wistar rats in a mildly novel open-field situation. Scandinavian Journal of Laboratory Animal Science 22(3), 265-269.
Open-field behaviour of individually gentled and nonhandled adult male Wistar rats was studied in a mildly novel test situation. The gentled rats were more active and showed fewer signs of fear on the first trial...

Han:Wist rats were housed after weaning in groups of one, two, three or four in stainless steel cages with aspen chip bedding, with or without wooden gnawing blocks. The use of the blocks was assessed...
