The NC3Rs: Pioneering better science


If you are a scientist, animal technician, veterinarian, regulator, funder or policy maker, the NC3Rs can help you to:

  • Drive scientific and technological developments that replace, reduce or refine the use of animals in research (the 3Rs)
  • Ensure your animal experiments are as robust and reproducible as possible
  • Provide the best welfare for laboratory animals

 

Science-led and evidence-based, we fund research and early careers, foster collaborations between universities and industry to develop and commercialise 3Rs technologies, and provide information on the latest advances to put the 3Rs into practice.
