Improving mouse welfare

Scientists at EARA member the University of Zurich, Switzerland, have reported on a new way to administer drugs to mice without injections.

The new method involves training the mice to voluntarily drink a drug from a small pipette, containing a sweetened solution, instead of having to inject it into the mouse’s stomach.

In results published in Lab Animals, the team showed that their new method reduced stress in the animal, and therefore improved the overall quality of the study.

The work has drawn praise from the Swiss 3R Competence Centre, who awarded the Young Investigator 3Rs Award to Joseph Scarborough for his contribution and his dedication in implementing the technique in other research groups.
