Primates in research facilities have complex social and cognitive needs requiring specialized welfare standards; housing, enrichment, and group management are the primary welfare challenges.
Primates used in research occupy a unique welfare position: their cognitive and social complexity means welfare deficits cause more profound suffering than in less cognitively complex species, while the scientific value attributed to their similarity to humans has historically been used to justify extensive use. Welfare standards for primates have advanced significantly: social housing is now broadly required, environmental enrichment is standard practice, and procedural pain management is mandated. Remaining gaps include the welfare impacts of research procedures themselves and the chronic stress of captivity even in enriched environments.
