Facts and figures

Each animal is recorded in detail and animal numbers are submitted annually to the Freiburg Regional Council. The Federal Institute for Risk Assessment publishes Germany-wide statistics on the animals used in experiments.

Animal experiments 2020 by animal species and number

Species Quantity Percentage
Mice 18.403 85%
Zebrafish 3.162 15%
Other fish 42 < 1%
Total 21.607 100%

Am MPI-IE werden vor allem Mäuse für die Versuche genutzt. Zebrafische und andere Fischarten, wie zum Beispiel Karpfen, Forellen, Neunaugen und Hechte, machen ca. 16% der eingesetzten Tiere aus.

Type of experiments according to severity

More than 40% of the animals are used for organ extraction without any treatment or experimental intervention.

In the actual animal experiments, most animals (46%) experience mild levels of distress and 10% experience moderate levels of distress. Less than 1% of the animals used are classified as "severe".

Severity definitions according to EU Directive 2010/63/EU

Non-recovery
Procedures performed entirely under general anaesthesia from which the animal does not awaken are classified as "non-recovery".


Mild
Procedures that are expected to cause minor pain, suffering or distress to the animal for a short period of time and procedures that do not significantly affect the welfare or general condition of the animal are classified as "mild".


Moderate
Procedures that are expected to cause moderate short-term pain, moderate suffering or distress or prolonged mild pain to the animals and procedures that are expected to cause moderate welfare or general distress to the animals shall be classified as 'moderate'.


Severe
Procedures that are likely to cause severe pain, suffering or distress to animals, or prolonged moderate pain, suffering or distress, and procedures that are likely to cause severe welfare or general distress to animals shall be classified as 'severe'.
