Mieske, P., Hobbiesiefken, U., Fischer-Tenhagen, C. et al. 2022. Bored at home?—A systematic review on the effect of environmental enrichment on the welfare of laboratory rats and mice. Frontiers in Veterinary Science 9, 899219.

Boredom is an emotional state that occurs when an individual has nothing to do, is not interested in the surrounding, and feels dreary and in a monotony. While this condition is usually defined for humans...

Kohler, J., Mei, J., Banneke, S. et al. 2022. Assessing spatial learning and memory in mice: Classic radial maze versus a new animal-friendly automated radial maze allowing free access and not requiring food deprivation.

The radial arm maze (RAM) is a common behavioral test to quantify spatial learning and memory in rodents. Prior attempts to refine the standard experimental setup have been insufficient. Previously, we demonstrated the feasibility of...

Aldhshan, M. S., Mizuno, T. M. 2022. Effect of environmental enrichment on aggression and the expression of brain-derived neurotrophic factor transcript variants in group-housed male mice. Behavioural Brain Research 433, 113986.

Social and environmental factors influence behavior via modulation of brain physiological functions. Environmental enrichment (EE) is an animal housing technique that provides complex sensory, motor, and social stimulation, leading to modifications in the innate aggressiveness...

Davies, J. R., Purawijaya, D. A., Bartlett, J. M. et al. 2022. Impact of refinements to handling and restraint methods in mice. Animals 12(17), 2173.

There is increasing evidence that, compared to non-aversive handling methods (i.e., tunnel and cupping), tail handling has a negative impact on mouse welfare. Despite this evidence, there are still research organisations that continue to use...

Kolbe, T., Lassnig, C., Poelzl, A. et al. 2022. Effect of different ambient temperatures on reproductive outcome and stress level of lactating females in two mouse strains. Animals 12(16), 2141.

Ambient temperature is an important non-biotic environmental factor influencing immunological and oncological parameters in laboratory mice. It is under discussion which temperature is more appropriate and whether the commonly used room temperature in rodent facilities...

Donaldson-Wing, M. 2022. Medicated jelly as a replacement for injectables and the use of Maropitant to manage itchy skin in mice. Animal Technology and Welfare 21(2), 134-136.

It is desirable to administer drugs by the least invasive route to (1) optimise welfare, (2) reduce the risk of injury to animal handlers and (3) minimise the impact of restraint and transient pain on...

Bartlett, J., Davies, J., Purawijaya, D. et al. 2022. Refinement of handling and dosing methods for rats and mice. Animal Technology and Welfare 21(2), 120-124.

Modified Handling for Mice: Handling mice by gripping the base of the tail has been shown to negatively impact animal welfare by increasing anxiety and aversion to handling. We aimed to refi ne the dosing...

Stevens, C., Dobbinson, K., Brook, E. et al. 2022. Report of the 2021 RSPCA/UFAW Rodent Welfare Group meeting. Animal Technology and Welfare 21(2), 83-91.

The RSPCA/UFAW Rodent Welfare Group has held a one-day meeting every autumn for the last 28 years, so that its members can discuss current welfare research, exchange views on welfare issues and share experiences of...

Reuser, A., Wenzel, K., Felix, S. B. et al. 2022. Simultaneous assessment of spontaneous cage activity and voluntary wheel running in group-housed mice. Scientific Reports 12(1), 4444.

Small animal models are frequently used to improve our understanding of the molecular and biological signaling pathways underlying the beneficial effects of physical activity and exercise. Unfortunately, when running wheels are employed, mice and rats...

Guillaumin, A., Vlcek, B., Wallén-Mackenzie, Å. 2022. Improving well-being and survival in the 6-OHDA lesion model of Parkinson´s disease in mice: Literature review and step-by-step protocol. Scandinavian Journal of Animal Science 48(1), 1-21.

Parkinson’s disease (PD) is the most common neurodegenerative motor disorder and primarily affects movement control but also a range of non-motor functions. With unknown etiology and lack of cure, much research is dedicated to unravel...
