Venipuncture and vaginal swabbing in an enclosure occupied by a mixed-sex group of stumptailed macaques (Macaca arctoides)

Procedures are described for vaginal swabbing and venipuncture in a gang‐caged, mixed‐sex group of stumptailed macaques. The design of the gang cages facilitated venipuncture and swabbing which were done without undue disturbance of the vivarium routine, without seriously stressing colony members, and without interfering with the monkeys' established social relationships.
