3Rs

Charles River is firmly committed to the 3Rs (Replacement, Reduction, and Refinement) and helps to reduce the number of animals used by emphasizing health and genetic integrity to decrease study data variability. We also partner with customers to develop study designs decreasing the number of animals needed and suggesting pilot studies where appropriate.
