Implementing the 3Rs


Replacement - methods which avoid or replace the use of animals.

Reduction - minimising the numbers of animals used - for example by improving the experimental design and statistical analysis used in a study.

Refinement - improving experimental procedures, and other factors affecting animals such as their housing and care, to reduce suffering and improve welfare throughout the animals’ lives.

Our work

Promoting the implementation of all 3Rs and developing practical ideas and recommendations for how this can be done is an integral part of the work of the research animals department.

This section of the site shows examples of our recent and ongoing work on the 3Rs -see the pages in the left hand menu. Providing information on these issues to countries in Eastern Europe and Asia is also part of our work.
