The 3Rs principles

The 3Rs principles were first introduced over 60 years ago and they establish the accepted standards for humane experimentation on animals. These principles are endorsed and incorporated by all responsible scientists and have become embedded in national and international legislation regulating the use of animals in scientific procedures.

The 3Rs are:
• Replacement – methods which avoid or replace the use of animals;
• Reduction – methods which minimise the number of animals used per experiment;
• Refinement – methods which minimise any suffering and improve animal welfare.

See here for more information on how the 3Rs operate.
