Captive Primate Welfare in Research Facilities

Non-human primates used in biomedical research require species-appropriate social environments and enrichment to maintain psychological wellbeing.

Key Facts

Macaques and marmosets are the most commonly used primates in research globally
Social isolation of primates causes severe psychological harm and stereotypic behaviours
The Three Rs framework requires refinement of housing to include social housing where possible
Some research protocols still require individual housing, creating welfare compromises
Refinement research has demonstrated that social housing improves experimental reliability

Welfare Considerations

Primates in research facilities are among the most cognitively complex animals used in science. Solitary housing causes documented psychological harm — including self-injurious behaviour, stereotypies, and abnormal social responses. Species such as macaques have evolved in complex social groups and suffer profoundly when denied social contact. The scientific case for social housing is strong: animals in better welfare conditions produce more reliable data. Moving toward social housing, environmental enrichment, positive reinforcement training, and early retirement to sanctuary represents both ethical and scientific progress.

What You Can Do

Support organisations advocating for higher welfare standards in primate research
Encourage institutions to publish their Three Rs compliance reports
Back legislation requiring social housing for research primates by default
Consider the welfare standards of research institutions when choosing which studies to support or fund
