Alternatives and "the 3 Rs"
Animal research legislation requires that “techniques that totally or partially replace the use of animals...must be sought and used wherever possible.”
If it is not possible to replace the use of animals, studies must be designed to use the minimum number of animals necessary to ensure scientific validity and minimise any possible adverse effects on the animals.
The strategy of replacing, reducing and refining the use of animals in research is known as “the 3 Rs” and is a central component of the legally binding Code of Practice.
