Evaluating an animal experiment helps you and your colleagues optimize future animal experiments, estimate discomfort in future animal experiments and identify unexpected discomfort. The welfare evaluation also contains the data necessary for the annual registration.
Within two weeks of removing the last animal from the experiment, and, for ongoing experiments, also at the beginning of each calendar year, you write a welfare evaluation. You send this to the laboratory animal coordinator and the Animal Welfare Body. The period of two weeks is important because there should still time to ask questions. We can also apply the lessons we learnt from the evaluation in other studies.
The welfare evaluation consists of two parts. The first part provides insight into (forced) deviations from the original work protocol and into unexpected effects or incidents that may have had an impact on well-being. It is important to learn from this for subsequent studies. The second part concerns the registration of animal experiments as we provide for the national and European annual figures. Partly for this reason, you must also evaluate tests in the interim when a new calendar year has started. You do this in January, so that this data can be included in the annual registration.
