Lab Animal 3Rs Implementation in Universities

How universities implement the 3Rs principles of Replacement, Reduction, and Refinement in animal research.

Key Facts

The 3Rs were proposed by Russell and Burch in 1959 and are now legally required
NC3Rs funds research into 3Rs methods and tools in the UK
Institutional Animal Care and Use Committees oversee 3Rs implementation in the US
Reduction strategies include better experimental design and sharing of data
Replacement includes in vitro models, organ-on-a-chip, and computer simulation

Welfare Considerations

Genuine 3Rs implementation can significantly reduce animal numbers and suffering in research while maintaining or improving scientific quality.
