Welfare Science

Zoo Primate Research and 3Rs

Research using captive primates raises significant welfare concerns, with the 3Rs framework of Replacement, Reduction, and Refinement providing principles for welfare improvement.

Key Facts

Primates are used in biomedical research for their physiological and cognitive similarity to humans
Great apes are prohibited from research in the EU reflecting their advanced cognitive abilities
Non-human primate research causes significant welfare harm through procedures and housing conditions
Alternatives including organoids and in vitro systems are progressively replacing some primate research
Housing standards for research primates lag behind zoo standards for the same species

Welfare Considerations

Primate research welfare involves the fundamental ethical question of whether the benefits of research justify the welfare costs to intelligent, sentient animals. Rigorous application of 3Rs principles that maximise Replacement, Reduction, and Refinement of animal use is the ethical minimum.

What You Can Do

Support organisations developing non-animal alternatives to primate research
Advocate for research primate housing standards equivalent to accredited zoo standards
Engage with scientific bodies about their 3Rs implementation in primate research programmes
