Xie, W., Palme, R., Schafmayer, C. et al. 2021. Distress analysis of mice with cervical arteriovenous fistulas. Animals 11(11), 3051.

The welfare of laboratory animals is a consistent concern for researchers. Its evaluation not only fosters ethical responsibility and addresses legal requirements, but also provides a solid basis for a high quality of research. Recently...

Prior, H., Blunt, H., Crossman, L. et al. 2021. Refining procedures within regulatory toxicology studies: Improving animal welfare and data. Animals 11(11), 3057.

During the development of potential new medicines or agrochemicals, an assessment of the safety profile to humans and environmental species is conducted using a range of different in silico and in vitro techniques in conjunction...

Mieske, P., Diederich, K., Lewejohann, L. 2021. Roaming in a land of milk and honey: Life trajectories and metabolic rate of female inbred mice living in a semi naturalistic environment. Animals 11(10), 3002.

Despite tremendous efforts at standardization, the results of scientific studies can vary greatly, especially when considering animal research. It is important to emphasize that consistent different personality-like traits emerge and accumulate over time in laboratory...

Rodriguez-Sanchez, R., Barnaby, E., Améndola, L. et al. 2021. Voluntary oral ingestion of a sedative prior to euthanasia with CO2: Behavioural responses of mice. Animals 11(10), 2879.

Laboratory mice are commonly euthanised with carbon dioxide (CO2); however, there is ample evidence that this gas is aversive. Previous work suggests that sedation achieved via injection with benzodiazepines prior to CO2 administration could reduce...

Travain, T., Valsecchi, P. 2021. Infrared thermography in the study of animals’ emotional responses: A critical review. Animals 11(9), 2510.

Whether animals have emotions was historically a long-lasting question but, today, nobody disputes that they do. However, how to assess them and how to guarantee animals their welfare have become important research topics in the...

Brajon, S., Morello, G. M., Capas-Peneda, S. et al. 2021. All the pups we cannot see: Cannibalism masks perinatal death in laboratory mouse breeding but infanticide is rare. Animals 11(8), 2327.

Perinatal mortality is a major issue in laboratory mouse breeding. We compared a counting method using daily checks (DAILY_CHECK) with a method combining daily checks with detailed video analyses to detect cannibalisms (VIDEO_TRACK) for estimating...

Xie, W., Kordt, M., Palme, R. et al. 2021. Diagnostic ability of methods depicting distress of tumor-bearing mice. Animals 11(8), 2155.

Subcutaneous tumor models in mice are the most commonly used experimental animal models in cancer research. To improve animal welfare and the quality of scientific studies, the distress of experimental animals needs to be minimized...

Obermueller, B., Castellani, C., Till, H. et al. 2021. An examination of nest-building behaviour using five different nesting materials in C57BL/6J and BALB/c mice. Animal Welfare 30(4), 467-477.

The aim of our study was to assess the nest-building behaviour of two mouse (Mus musculus) strains using different nesting materials and examine possible sex- and housing-specific effects. Adult mice of two strains (C57BL/6J; n...

Burn, C. C., Popat, R. 2021. A tunnel is not enough: Mice benefit from in-cage provision of a communal shelter as well as a handling tunnel. Animal Technology and Welfare 20(3), 203-210.

Mouse shelters can provide mice with security, help them thermoregulate, offer darkness to prevent damage to their eyes and enable climbing and gnawing opportunities. For laboratory mice, there is a vast array of commercially available...
