Ball, R. S. 2006. Issues to consider for preparing ferrets as research subjects in the laboratory. ILAR Journal 47(4), 348-357.

Successful housing requires knowledge of ferret behaviors including social behavior, eating habits, a general inquisitive nature, and a species-typical need to burrow and hide. Regular handling is necessary to maintain well-being. A ferret health care...

Oteham, C. P. 2010. Effects of specific environmental enrichment contributing to litter size and attrition rate of TRP1/TGfβ transgenic mice in a breeding colony. American Association for Laboratory Animal Sci

In previous studies of environmental enrichment of mice it has been determined that certain types of mice are affected by manipulation of their living environment. Some have effects on cognitive memory and some affect the...

Gaskill, B., Garner, J. P., Pritchett-Corning, K. 2011. Energy reallocation to breeding performance through improved behavioral thermoregulation. American Association for Laboratory Animal Science [AALAS] Meeting Official Progra

Mice are housed at temperatures which increase their basal metabolic rates and impose high energy demands to maintain core temperatures. Thus, energy may be reallocated from other biologic processes to increase heat production. We hypothesized...

Gaskill, B., Winnicker, C. L., Garner, J. P. et al. 2011. The naked truth: Breeding performance in outbred and inbred strains of nude mice with and without nesting material. American Association for

In laboratories, mice are housed at ambient temperatures between 20 to 24 °C, which is below their lower critical temperature of 30 °C, but comfortable for human workers. Thus, mice are thermally stressed, which can...

Griess, R. S. 2011. Environmental enrichment improves fertility and pup survival. Tech Talk [The Newsletter for Laboratory Animal Science Technicians] 16(1), 2-3.

Historically, we have added approximately half a cup of shredded aspen bedding for nest making into each littering cage. This procedure was continued as we looked into additional environmental enrichment. There are many types of...

Neves, S. 2011. Effects of environmental enrichment on the production of C57BL/6 mice kept in different housing systems. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 788 (Abstract #P201).

The goal of this study was to evaluate the effects of environmental enrichment on the performance of C57BL/6 mice kept in conventional animal facilities (open cage; OC) and individually ventilated caging system (IVC). We analyzed...

Paula, A. A., Goyeneche, L., Crispo, M. 2011. Refining housing and husbandry techniques in transgenic mice through environmental enrichment. American Association for Laboratory Animal Science

Dynamic changes in housing and husbandry techniques based on the concept of 3Rs should be included as routine practice in breeding and experimental animal facilities tending to improve animal welfare. Immunosupressed mice are susceptible to...

Merriman, D. K., Lahvis, G., Jooss, M. et al. 2012. Current practices in a captive breeding colony of 13-lined ground squirrels (Ictidomys tridecemlineatus). Lab Animal 41(11), 315-325.

The authors provide an update to their 2006 report on the successful large-scale captive breeding of the 13-lined ground squirrel (TLGS; Ictidomys tridecemlineatus) in their colony, now a single-source supplier of purpose-bred TLGSs for several...

Shair, H. N., Nunez, Y., Osman, M. M. 2012. Enrichment materials do not negatively affect reproductive success and offspring survival and weight in mice. Lab Animal 41(1), 14-19.

Environmental enrichment is designed to improve the overall welfare of laboratory animals, including mice. Few studies have directly assessed the effects of different types of enrichment on mouse offspring survival and growth. The authors examined...

Andrist, C. A., Bigler, L. M., Wurbel, H. W. et al. 2012. Effects of group stability on aggression, stress and injuries in breeding rabbits. Applied Animal Behaviour Science 142(3-4), 182-188.

On Swiss rabbit breeding farms, group-housed does are usually kept singly for 12 days around parturition to avoid pseudogravidity, double litters and deleterious fighting for nests. After this isolation phase there is usually an integration...
