Felgenhauer, J. L., Brune, J. E., Long, M. E. et al. 2020. Evaluation of nutritional gel supplementation in C57BL/6J mice infected with mouse-adapted Influenza A/PR/8/34 virus. Comparative Medicine 70(6), 471-486.

Mice are a common animal model for the study of influenza virus A (IAV). IAV infection causes weight loss due to anorexia and dehydration, which can result in early removal of mice from a study...

Elmi, A., Galligioni, V., Govoni, N. et al. 2020. Quantification of hair corticosterone, DHEA and testosterone as a potential tool for welfare assessment in male laboratory mice. Animals 10(12), 2408.

Steroids, providing information regarding several biological patterns including stress and sexual behavior, have been investigated in different matrices in laboratory mice. Data regarding hair quantification, indicative of longer timespans when compared to blood and saliva...

Abela, C. 2020. Alternative training method using a mouse simulator in intravenous lateral tail vein procedures. Animal Technology and Welfare 19(3), 249-250.

The purpose of this study was to reduce or replace mouse cadavers for use in procedural training. All participants had mixed experience in various technical procedures such as oral gavage, intraperitoneal injections, etc., but none...

Hamilton, E. 2020. Improving animal welfare at Newcastle University by introducing the low stress handling of mice. Animal Technology and Welfare 19(3), 185-194.

The primary focus of this project was to introduce the low stress handling of mice to Newcastle University and resulting in all researchers and technicians using this method. It aimed to bring a team together...

Meikle, M. N., Arévalo, A. P., Schlapp, G. et al. 2020. Long-term effect of environmental enrichment on reproductive performance of Swiss Webster mice and their female offspring. Animals 10(8), 1438.

The aim of this study was to evaluate the effect of an environmental enrichment (EE) plan on the reproductive performance of Swiss Webster mice and their female offspring used as recipients for embryo transfer. A...

Hohlbaum, K., Corte, G. M., Humpenöder, M. et al. 2020. Reliability of the mouse grimace scale in C57BL/6JRj mice. Animals 10(9), 1648.

To maintain and foster the welfare of laboratory mice, tools that reliably measure the current state of the animals are applied in clinical assessment. One of these is the Mouse Grimace Scale (MGS), a coding...

Grífols, R., Zamora, C., Ortega-Saez, I. et al. 2020. Postweaning grouping as a strategy to reduce singly housed male mice. Animals 10(11), 2135.

Rearing laboratory mice in groups is important since social isolation after weaning induces brain alterations, which entails behavioral abnormalities in adulthood. Age is an important factor when grouping males of different litters due to inter-male...

Vogt, M. A., Mertens, S., Serba, S. et al. 2020. The ‘Cage Climber’ - A new enrichment for use in large-dimensioned mouse facilities. Applied Animal Behaviour Science 230, 105078.

Environmental Enrichment has been shown in experimental contexts to have clear and often beneficial effects on animal physiology and behavior. Housing prior to experiments can represent a large proportion of an animal’s living conditions, and...

van der Vinne, V., Pothecary, C. A., Wilcox, S. L. et al. 2020. Continuous and non-invasive thermography of mouse skin accurately describes core body temperature patterns, but not absolute core temperature. Scientific Reports 10(1), 20680.

Body temperature is an important physiological parameter in many studies of laboratory mice. Continuous assessment of body temperature has traditionally required surgical implantation of a telemeter, but this invasive procedure adversely impacts animal welfare. Near-infrared...

Theil, J. H., Ahloy-Dallaire, J., Weber, E. M. et al. 2020. The epidemiology of fighting in group-housed laboratory mice. Scientific Reports 10(1), 16649.

Injurious home-cage aggression (fighting) in mice affects both animal welfare and scientific validity. It is arguably the most common potentially preventable morbidity in mouse facilities. Existing literature on mouse aggression almost exclusively examines territorial aggression...
