Macaque Research Welfare and Alternatives

Macaques are widely used in biomedical and behavioral research. Improving their welfare within research settings and developing alternatives are parallel welfare priorities.

Key Facts

Approximately 100,000 macaques are used in research annually worldwide
Macaques used in neuroscience research often undergo head restraint and implant procedures
Social housing dramatically improves welfare but is still not universal in macaque facilities
Macaques have complex social needs and sophisticated cognitive abilities
Alternatives to primate research including organoids and computer models are advancing

Welfare Considerations

Macaques used in research face specific welfare challenges from the highly invasive procedures used in neuroscience — head implants, chair restraint, and extended sessions without social contact. Post-surgical recovery management and pain assessment are critical welfare points. The social nature of macaques makes individual housing, still common in research settings, a significant welfare harm. Positive reinforcement training for research cooperation reduces stress and can eliminate coercive restraint for some procedures. The development of non-primate alternatives advances on multiple fronts.

What You Can Do

Support funding for non-primate research alternatives
Advocate for mandatory social housing standards in macaque research facilities
Support the development of organ-on-chip and other replacement technologies
Choose products from companies that fund alternative research method development
Engage with institutions on their macaque welfare standards through public consultations
