Nøgaard, S. A., Sand, F. W., Sørensen, D. B. et al. 2020. Four- and six-hour urinary albumin excretion is a valuable alternative to 24-h urinary albumin excretion in male db/db mice. Animal Welfare 29(2), 143-149.

In mouse (Mus musculus) models of diabetic nephropathy (DN), one of the most important read-outs is the 24-h urinary albumin excretion (UAE). The 24-h urine collection is usually performed by single housing mice in metabolic...

Ritchie, A., Collier, P., Clare, P. et al. 2019. Food for thought: The development of drug loaded diets improve both science and welfare. Animal Technology and Welfare 18(3), 222-224.

In our facility, we use several hormone dependent tumour models with supplementation delivered via slow release subcutaneously implanted pellets, implanted via trochar. For example, breast tumours which rely on 17-β-Estradiol. Administration of E2 supplementation can...

Kaye, N. 2019. A technologist-led approach to altering the culture of care regarding blood sampling. Animal Technology and Welfare 18(3), 213-216.

This poster will describe the implementation by Animal Technologists and Named Persons of a well published refined bleeding technique. Establishing The Francis Crick Institute from legacy institutes required a standardised approach for many techniques, including...

Morgunowicz, A., Cavanagh, C., Nikitochkina, S. et al. 2019. Increased incidence of spontaneous seizures in laboratory mice in an IVC environment. Animal Technology and Welfare 18(3), 159-166.

Over the past decade, there has been an enormous shift away from the use of open top rodent cages to the use of individually ventilated cages (IVCs). This has brought with it many benefits, including...

Abdelrahman, A., Kumstel, S., Zhang, X. et al. 2019. A novel multi-parametric analysis of non-invasive methods to assess animal distress during chronic pancreatitis. Scientific Reports 9, 14084.

Ethical responsibility, legal requirements and the need to improve the quality of research create a growing interest in the welfare of laboratory animals. Judging the welfare of animals requires readout parameters, which are valid and...

Barabas, A. J., Aryal, U. K., Gaskill, B. N. 2019. Proteome characterization of used nesting material and potential protein sources from group housed male mice, Mus musculus. Scientific Reports 9, 17524.

Laboratory mice (Mus musculus) communicate a variety of social messages through olfactory cues and it is often speculated that these cues are preserved in nesting material. Based on these speculations, a growing number of husbandry...

Lidster, K., Owen, K., Browne, W. J. et al. 2019. Cage aggression in group-housed laboratory male mice: An international data crowdsourcing project. Scientific Reports 9, 15211.

Aggression in group-housed laboratory mice is a serious animal welfare concern. Further understanding of the causes of mouse aggression could have a significant impact on a large number of laboratory animals. The NC3Rs led a...

Gouveia, K., Hurst, J. L. 2019. Improving the practicality of using non-aversive handling methods to reduce background stress and anxiety in laboratory mice. Scientific Reports 9, 20305.

Handling can stimulate stress and anxiety in laboratory animals that negatively impacts welfare and introduces a confounding factor in many areas of research. Picking up mice by the tail is a major source of handling...

Campos-Luna, I., Miller, A., Beard, A. et al. 2019. Validation of mouse welfare indicators: A Delphi consultation survey. Scientific Reports 9, 10249.

This study aims to identify the most valid, reliable and practicable indicators of laboratory mouse welfare using the Delphi consultation technique. The effective assessment of laboratory mouse welfare is a fundamental legal and moral requirement...

Wang, X., Zhang, Y., Lu, T. et al. 2019. The effect of cage ventilation rate on the health of mice housed in Individually Ventilated Cages. Scandinavian Journal of Laboratory Animal Science 45(3).

The number of air changes per hour (ACH), an important index for individually ventilated cages (IVC), strongly affects the cage microenvironment and the health of laboratory animals. The objective of this study was to determine...
