3Rs Alternatives: Technologies, and Approaches

3Rs alternatives refer to the reduction, refinement, and replacement of animal use in research, testing, and teaching. The concept was developed by Russell and Burch in a 1959 book entitled Principles of Humane Experimental Technique. A fundamental goal of the Animal Welfare Act and the accompanying regulations is the minimization of animal pain and distress via the consideration of alternatives and alternative methods.
