Primate Welfare in Research Settings

Non-human primates used in research have complex social and cognitive needs that present significant welfare challenges.

Key Facts

Approximately 70,000 non-human primates are used in research globally each year
Macaques are the most commonly used primate species in biomedical research
UK law requires primates to be kept in social groups with environmental enrichment
Single housing of primates is only permitted for specific scientific or veterinary reasons
Primates in research show high rates of psychological problems when inadequately housed

Welfare Considerations

Non-human primates have cognitive and social complexity that makes research settings inherently welfare-challenging. These animals form lasting social bonds, have sophisticated communication, and experience complex emotions. Inadequate socialisation, restraint, and invasive procedures cause significant suffering. The 3Rs framework is particularly important for primates — replacement with non-animal models should always be the first objective, with refinement of necessary primate research as a priority.
