Mwobobia, R., Abelson, K., Kanui, T. 2020. Housing behaviour of the naked mole rat (Heterocephalus glaber) under laboratory conditions. Scandinavian Journal of Laboratory Animal Science 46(1), 16-24.

The naked mole rat (Heterocephalus glaber) is a rodent that has gained importance as a biomedical research model for various conditions including hypoxic brain injury, cancer and nociception. It is captured from the wild and...

Dupepe, L. M., Dauchy, R. T., McAndrew, D. et al. 2020. Eliminating light-at-night contamination during a lab animal facility renovation. Laboratory Animal Science Professional 8(5) (September/October), 60-62.

Relocating laboratory animal research from one animal facility room to another in advance of major renovations can be a daunting task for scientists and animal care personnel alike. This is especially so regarding controlled lighting...

Khoo, S. Y.-S., Correia, V., Uhrig, A. 2020. Nesting material enrichment reduces severity of overgrooming-related self-injury in individually housed rats. Laboratory Animals 54(6), 546-558.

Individual or singly-housing laboratory rats is common in many animal facilities, but has an adverse impact on the welfare of this social species. It has previously been shown that a small proportion of individually housed...

Zieglowski, L., Kümmecke, A., Ernst, L. et al. 2020. Severity assessment using three common behavioral or locomotor tests after laparotomy in rats: A pilot study. Laboratory Animals 54(6), 525-535.

The aim of this pilot study was to evaluate whether behavioral or locomotor tests (Open Field (OF), rotarod (RR), and CatWalk (CW)) can help assess the severity of laparotomy in rats. The new EU Directive...

Laferriere, C. A., Pang, D. S. 2020. Review of intraperitoneal injection of sodium pentobarbital as a method of euthanasia in laboratory rodents. JAALAS 59(3), 254–263.

Euthanasia is one of the most commonly performed procedures in biomedical research, involving tens of millions of animals in North America and Europe every year. The use of sodium pentobarbital, injected intraperitoneally, for killing rodents...

Shomer, N. H., Allen-Worthington, K. H., Hickman, D. L. et al. 2020. Review of rodent euthanasia methods. JAALAS 59(3), 242–253.

The optimal choice of euthanasia method for laboratory rodents depends on a number of factors, including the scientific goals of the study, the need to minimize animal pain and/or distress, applicable guidelines and laws, the...

Zude, B. P., Jampachaisri, K., Pacharinsak, C. 2020. Use of flavored tablets of gabapentin and carprofen to attenuate postoperative hypersensitivity in an incisional pain model in rats (Rattus norvegicus). JAALAS 59(2), 163–169.

Providing postoperative analgesia to rats by oral administration, compared with injections, reduces stress from frequent handling and is technically easier for investigators. The purpose of this study was to investigate whether bacon-flavored tablets containing gabapentin...

Blackburn, N., Cronshaw, G., Mitchell, M. 2020. Environmental enrichment for a small colony of rats. Animal Technology and Welfare 19(2), 158.

Due to limited space and resource for equipment, we came up with some easy and cost-effective ways to improve enrichment for the rat colony. Since implementing our protocol for forage feeding and out of cage...

Stevens, C., Finnegan, E., Clarkson, J. et al. 2020. Report of the 2019 RSPCA/UFAW Rodent Welfare meeting. Animal Technology and Welfare 19(2), 101-111.

The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 26 years, so that its members can discuss current welfare research, exchange views on welfare issues, and share experiences of...
