Includes refinements to diet, bedding or flooring, cage changing, lighting, temperature, noise levels, etc.

Meller, A., Kasanen, I., Rukšėnas, O. et al. 2011. Refining cage change routines: Comparison of cardiovascular responses to three different ways of cage change in rats. Laboratory Animals 45(3), 167-173.

Cage change is one of the unavoidable routines in laboratory rodent care. However, cage change disrupts the rodents’ olfactory environment and can evoke stress reactions. In this study, the short-term cardiovascular responses to three different...

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...

Rasmussen, S., Miller, M., Filipski, S. B. et al. 2011. Cage change influences serum corticosterone and anxiety-like behaviors in the mouse. JAALAS 50(4), 479-483.

Environmental variables and husbandry practices can influence physiology and alter behavior in mice. Our study evaluated the effects of cage change on serum corticosterone levels and anxiety-like behaviors in C57BL/6 male mice. We examined the...

Reed, M., Goldsteen, D. L., Moore, E. et al. 2011. Environmental enrichment program in transgenic mouse breeding colonies. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 779 (Abstract #P160).

Results of studies on the benefits of environmental enrichment in group-housed mice and breeding colonies are often inconsistent and conflicting. After observing a significant drop in some of the genetically engineered mice (GEM) breeding colonies...

Schipper, P., Nonkes, L. J., Karel, P. et al. 2011. Serotonin transporter genotype x construction stress interaction in rats. Behavioural Brain Research 223(1), 169-175.

A well-known example for gene x environment interactions in psychiatry is the one involving the low activity (s) allelic variant of the serotonin transporter (5-HTT) promoter polymorphism (5-HTTLPR) that in the context of stress increases...

Sheets, M. D., Lindstrom, K. E., Carbone, L. G. 2011. The effects of sanded (bottom only) perches on finch feet. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 779 (Abstract #P157).

Birds that are kept in captivity often require nail trims, presumably due to the lack of opportunity to wear the nails down on natural substrates. For many birds, restraint for the nail trim may result...

Young, M. T., French, A. L., Clymer, J. W. 2011. An effective, economical method of reducing environmental noise in the vivarium. JAALAS 50(4), 513-515.

High levels of ambient noise can have detrimental effects on laboratory animal wellbeing and may affect experimental results. In addition, excessive noise can reduce technician comfort and performance. This study was performed to determine whether...

Zahorsky-Reeves, J. 2011. The choice of bedding substrate, route of blood collection, and method of glucose determination all affect fasting blood glucose levels in C57BL/6 mice. American Association for Laboratory

This study compared 4 bedding substrates (corncob, paper, hardwood chip, and wire-bottomed cage inserts) and 2 routes of blood collection (lateral tail vein and retroorbital sinus) in 6 male C57BL/6NCrl mice. Mice were maintained with...
