Reichert, M., Koewler, N., Hargis, A. M. et al. 2022. Effects of hair removal creams on mouse skin. Laboratory Animal Science Professional 10(3) (May/June), 46-47.

Human hair removal brands such as Nair™ are sometimes used in research to remove hair from mice before surgery, imaging, and other procedures.1,3 While the use of these depilatory creams in rodent research is relatively...

Scorrano, F. 2022. A new feeder device to provide cleaner and accessible diet gel to laboratory mice. Laboratory Animal Science Professional 10(2) (March/April), 50-52.

Gel solutions are simple to use, have a relative long shelf life and can be delivered with plastic cups or pouches. A common issue encountered by many institutions is that the gel becomes soiled quickly...

LaFollette, M. R. 2022. Refined ways to pick up mice. Laboratory Animal Science Professional 10(2) (March/April), 46-48.

As part of our commitment to continuous improvement of laboratory animal welfare, the North American 3Rs Collaborative (NA3RsC) brought together several experts to examine the evidence, impact, and practicality of alternative methods for picking up...

Ziegler, A. A., Grobe, C. C., Reho, J. J. et al. 2022. Short-term housing in metabolic caging on measures of energy and fluid balance in male C57BL/6J mice (Mus musculus). JAALAS 61(2), 132-139.

Metabolic caging is an important tool for quantitative urine and feces collection in rodents, although significant limitations and problems accompany its use. Despite strong opinions among investigators regarding the effects of metabolic caging on energy...

Nicolis, I. N., Beale, C. N., Bidot, W. A. et al. 2022. Performance and consistency of circulating warm water blankets for rodents. JAALAS 61(1), 96-100.

General anesthesia as used for rodent research can have adverse effects on physiologic mechanisms. Thermoregulation is often greatly inhibited, with resultant deleterious effects on cardiac and respiratory function. These potential effects can be mitigated by...

Martins, T., Matos, A. F., Soares, J. et al. 2022. Comparison of gelatin flavors for oral dosing of C57BL/6J and FVB/N mice. JAALAS 61(1), 89-95.

Precise oral dosing in rodents is usually achieved by intragastric gavage. If performed incorrectly due to technical difficulties, inexperience, or animal resistance, oral gavage may have animal welfare implications such as esophageal and gastric rupture...

Merley, A. L., Hubbard, J. S., Rendahl, A. K. et al. 2022. Behavioral and physiologic effects of dirty bedding exposure in female ICR mice. JAALAS 61(1), 42-51.

Exposure of sentinel mice to dirty bedding is commonly used in health monitoring programs to screen colonies for clinical and subclinical disease. Despite the potential stressors present in dirty bedding, including but not limited to...

Stover, M. G., Villano, J. S. 2022. Evaluation of various IVC systems according to mouse reproductive performance and husbandry and environmental parameters. JAALAS 61(1), 31-41.

IVC systems are marketed for improving the health and management of mouse colonies. The current study compared mouse reproductive performance and husbandry and environmental parameters among 3 high-density (HD) IVC rack systems (RS1, RS2, and...

Kitchenham, L., Nazal, B., Adcock, A. et al. 2022. Why does lifelong conventional housing reduce the sociability of female mice? Applied Animal Behaviour Science 246, 105532.

Compared to peers raised in well-resourced, 'enriched' environments (‘EE’), female laboratory mice from conventional barren cages are more aggressive to their cage-mates, and less sociable with familiar non-cage-mates (especially if these too are from conventional...
