Rhesus macaques are highly intelligent social primates commonly kept in research facilities and zoos. Their complex social and cognitive needs demand sophisticated welfare provisions.
Rhesus macaques have sophisticated social, cognitive, and behavioural needs that make their captive management particularly demanding. The most critical welfare requirement is appropriate social housing in stable, compatible groups with adequate space to establish and maintain social hierarchies without chronic conflict. In research facilities, even brief periods of social isolation cause measurable physiological stress responses, highlighting how fundamental social contact is to their welfare. Foraging enrichment that distributes food spatially and temporally across the enclosure mimics natural foraging patterns and occupies cognitive resources productively. Managing inter-individual aggression, particularly during resource competition, requires careful enclosure design with multiple feeding stations, escape routes, and visual barriers.
