Balafas, E., Stasinopoulou, M., Alexakos, P. et al. 2018. Synchronisation of oestrous cycle on C57BL/6J mice after the introduction of a hanging perforated container with bedding soaked by the excretions of male mice.

Synchronisation of oestrous cycle is a commonly used method to manage pregnancies either for breeding or for research purposes. Based on Whitten effect, the aim of our study was to introduce a new refined method...

Swan, A. 2018. Refining mouse handling - do we or don't we? An animal technologist's perspective. Animal Technology and Welfare 17(2), 130-131.

Recent research in the industry identified that picking up mice in a tunnel or cupping them in the hand significantly reduces their stress levels. As Animal Tecgnologists, we could see advantages and disadvantages with this...

Galvin, M., Lallo, A., Brown, S. et al. 2018. Refinement of tumour passage by optimisation of the tissue disaggregation protocol. Animal Technology and Welfare 17(2), 101-103.

Surgical implantation of tumour pieces has been used regularly in the passage of tumour models. This involves an invasive surgical procedure, carried out under anaesthesia, ensuring mice have adequate pain relief and peri-operative care. The...

Polissidis, A., Zelelak, S., Nikita, M. et al. 2017. Assessing the exploratory and anxiety-related behaviors of mice. Do different caging systems affect the outcome of behavioral tests? Physiology & Behavior 177, 68-73.

Ample studies have shown that housing can affect the health, welfare and behavior of mice and therefore, the outcomes of certain experiments. The aim of this study was to investigate if three widely used housing...

Lahger, C., Laska, M. 2018. Behavioral responses of CD-1 mice to conspecific and heterospecific blood odors and to a blood odor component. Physiology & Behavior 184, 2015-210.

The odor of blood may have both aversive and attractive properties for mammals, depending on the species of the odor donor and the species perceiving the odor. To better understand the informational content of blood...

Walker, M., Mason, G. 2018. A comparison of two types of running wheel in terms of mouse preference, health, and welfare. Physiology & Behavior 191, 82-90.

Voluntary wheel running occurs in mice of all strains, sexes, and ages. Mice find voluntary wheel running rewarding, and it leads to numerous health benefits. For this reason wheels are used both to enhance welfare...

Mei, J., Riedel, N., Grittner, U. et al. 2018. Body temperature measurement in mice during acute illness: Implantable temperature transponder versus surface infrared thermometry. Scientific Reports 8, 3526.

Body temperature is a valuable parameter in determining the wellbeing of laboratory animals. However, using body temperature to refine humane endpoints during acute illness generally lacks comprehensiveness and exposes to inter-observer bias. Here we compared...

Clarkson, J. M., Dwyer, D. M., Flecknell, P. A. et al. 2019. Handling method alters the hedonic value of reward in laboratory mice. Scientific Reports 8, 2448.

Mice are the most widely used model species for drug discovery and scientific research. Consequently, it is important to refine laboratory procedures and practices to ensure high standards of welfare and scientific data quality. Recent...

Kendall, L. V., Wegenast, D. J., Smith, B. J. et al. 2016. Efficacy of sustained-release buprenorphine in an experimental laparotomy model in female mice. JAALAS 55(1), 66–73.

Mice purportedly require dosing with the opioid buprenorphine (Bup-HCl) at least every 8 to 12 h to maintain an adequate plane of analgesia. Here we used an experimental laparotomy model to determine the clinical efficacy...

Boivin, G. P., Bottomley, M. A., Schiml, P. A. et al. 2017. Physiologic, behavioral, and histologic responses to various euthanasia methods in C57BL/6NTac male mice. JAALAS 56(1), 69-78.

Rodent euthanasia using exposure to increasing concentrations of CO2 has come under scrutiny due to concerns of potential pain during the euthanasia process. Alternatives to CO2, such as isoflurane and barbiturates, have been proposed as...
