Keeping giraffes in cold environments in zoos may place a burden on them. This study aimed to improve giraffe husbandry in cold environments by supplying warm drinking water in addition to a normal, ambient temperature...

Bárdos, B., Nagy, I., Gerencsér, Z. et al. 2022. Nest material preference of wild mouse species in laboratory housing. Applied Sciences 12(11), 5750.

Our research examined the nest-building characteristics of two mouse species native to Hungary, the mound-building mouse (Mus spicilegus) and the house mouse (Mus musculus), under laboratory housing conditions. In indoor housing, the nest-building material plays...

Vize, E., Westwood, C., Garner, P. 2023. Bamboo preference in a pair of captive red panda, Ailurus fulgens. RATEL (Journal of the Association of British and Irish Wild Animal Keepers) 50(2), 4-5.

For this study, two female red pandas, Pema and Tika, were observed. They are twin sisters and were both six years old at the time of the study. Observations were conducted over twelve days.This study...

Sansome, H. 2022. A tale of two sloths. RATEL (Journal of the Association of British and Irish Wild Animal Keepers) 49(3), 6-8.

Designed to improve their welfare by reducing the need for restraint and/or general anesthetic where possible. We have been working to improve the husbandry management of our 1.1 Linne’s two-toed (or fingered) sloths (Choloepus didactylus)...

Jones, T., Thaweethai, T., Molk, D. et al. 2022. Evaluation and refinement of a spot-change–only cage management system for mice. JAALAS 61(6), 650–659.

Maximizing operational efficiency while maintaining appropriate animal housing conditions is a continuous focus of research animal care programs. Our institution’s longstanding approach to cage-change management included scheduled cage changes every 2 wk, with spot changes...

Gates, K. V., Alamaw, E., Jampachaisri, K. et al. 2023. Efficacy of supplemental diet gels for preventing postoperative weight loss in mice (Mus musculus). JAALAS 62(1), 87–91.

This study investigated whether the use of commercially available diet gels prevented the postoperative weight loss associated with major survival surgery in mice. C57BL/6 mice were divided into 3 groups (n = 9 per group)...

Dauchy, R. T., Blask, D. E. 2023. Vivarium lighting as an important extrinsic factor influencing animal-based research. JAALAS 62(1), 3–25.

Light is an extrinsic factor that exerts widespread influence on the regulation of circadian, physiologic, hormonal, metabolic, and behavioral systems of all animals, including those used in research. These wide-ranging biologic effects of light are...

Clancy, B. M., Theriault, B. R., Turcios, R. et al. 2023. The effect of noise, vibration, and light disturbances from daily health checks on breeding performance, nest building, and corticosterone in mice. JAALAS 62(4), 291–302.

At our institution, the techniques that technicians use for health checks vary for mice housed in cages on individually ventilated caging (IVC) racks. If the mice cannot be adequately visualized, some technicians partially undock the...

Cho, E., Walsh, C. A., D’Angelo-Gavrish, N. M. et al. 2023. Effects of housing density on reproductive performance, intracage ammonia, and welfare of mice continuously housed as breeders in standard mouse and rat caging. JAALAS 62(2), 116–122.

Maintaining compliance with cage density recommendations in The Guide for the Care and Use of Laboratory Animals precludes continuous trio breeding in standard-sized mouse cages. This study evaluated and compared several parameters of reproductive performance...

Barabas, A. J., Darbyshire, A. K., Schlegel, S. L. et al. 2022. Evaluation of ambient sound, vibration, and light in rodent housing rooms. JAALAS 61(6), 660–671.

Excessive sound, vibration, and light are detrimental to rodent welfare, yet these parameters are rarely recorded in vivaria. Whether housing environments exceed the suggested thresholds and which specific factors may alter these parameters is generally...
