Research with laboratory animals

At Leiden University, for some of our research we use laboratory animals. We conduct this research in a responsible way and only when there is no other viable alternative. We ensure the best possible quality of life for the animals and uphold high standards for the quality of the research. In this dossier you can read how we do this.

Why do we use laboratory animals?

We use laboratory animals to answer research questions. However, we do so only when there is no alternative, and we cannot answer a question in any other way. Read here why we conduct animal experiments.

How do we ensure that research involving laboratory animals is conducted responsibly?

Animal experiments are not undertaken lightly; we are working with sentient beings. As scientists, we have a great responsibility to handle laboratory animals with care. Read here how we consider and justify this.

What research at Leiden University involves the use of laboratory animals?

At Leiden University, in both our biomedical and biological research, we use laboratory animals. Learn more about these specific areas of research and the goals we aim to achieve through these studies.

Are there alternatives to animal experiments?

We conduct as few animal experiments as possible. Additionally, we are constantly seeking ways to Replace, Reduce and Refine animal experiments, known as the 3Rs. Read here what that entails.

How does Leiden University ensure the welfare of laboratory animals?

We make every effort to provide the best possible life for our laboratory animals. The Animal Welfare Body is responsible for this. We have specialised animal facilities for various types of laboratory animals. Read here how we ensure the welfare of our animals.

Are all researchers allowed to work with laboratory animals?

Scientists working with laboratory animals at our institution undergo training on animal experimentation. This training equips researchers with the knowledge to handle laboratory animals responsibly. Read more about the required education and training here.
