What is the 3R principle?

The 3R principle - Replace, Reduce, Refine - was introduced to science in 1959 by a book entitled "The principles of humane experimental technique" by W.M.S. Russell and R.L. Burch. Various definitions of the terms exist by now. However, in general "Replace" refers to the replacement of animal experiments, "Reduce" to the reduction of the number of animals used in an experiment, and "Refine" to an improvement of the housing and experimental conditions for the animals.
