3Rs Databases are essential tools for researchers to refine and reduce laboratory animal experimentation

The 3Rs-Centre ULS has initiated the 3Rs Database Programme. This programme makes 3Rs information freely available and aims to contribute to the implementation of the 3Rs in animal research. The database programme exists of two databases, the Interspecies Database (1) and the Humane Endpoints website (2).


The homepage of the Interspecies Database

1. The Interspecies Database (www.interspeciesinfo.com) provides insight into physiological, anatomical and biochemical parameters of different animal species and humans. By using the database, researchers can design their experiments smarter with respect to the choice of an animal model. This could lead to a reduction in the number of experimental animals. Above all, this improves the scientific research quality. Users have indicated a reduction of on average 20% of laboratory animals annually, while some users reported a reduction of up to 40%. The website was initiated by the Dutch Institute for Public Health and the Environment (RIVM), which is responsible for the database content.

2. The Humane Endpoints website (www.humane-endpoints.info) provides information about humane endpoints and teaches how to recognize humane endpoints in rodents and fish. This helps prevent further suffering for the animals by removing the animals from the experiment (e.g. euthanizing the animals) or by applying analgesia. The website contributes to refinement: the prevention of unnecessary suffering in laboratory animals. The website is already successfully used in several laboratory animal science courses worldwide.

Both information sources do not receive any subsidies and therefore their future rely on donations and gifts. You can help keeping the websites available by donating only a small amount of money for the Interspecies Database or the Humane Endpoints website. We are happy with all donations and thank you very much for your help!
