title: Reproductive success of wild-caught and captive-bred cynomolgus macaques at a breeding facility.
abstract: The revised European Directive 2010/63/EU on the protection of animals used for scientific purposes encourages the scientific community to consider the feasibility of transitioning from the use of wild-caught breeders toward the exclusive use of captive-born breeders in non-human primate breeding centers. Little is known about how such a transition will affect animal health, productivity and accompanying husbandry practices. These concerns are important both for the efficient operation of a breeding facility and for the optimal welfare of the animals in its care. The authors analyzed records of wild-caught and captive-born female cynomolgus macaques (Macaca fascicularis) used for breeding at a facility between 2006 and 2011. Productivity was measured by proportional birth rate and interbirth interval; perinatal mortality was quantified by cause and type of death; and body condition was estimated using recorded visual assessments. Captive-born breeders generally showed lower productivity, higher perinatal mortality and poorer body condition than wild-caught breeders in the same husbandry conditions. These findings indicate that facilities transitioning to the use of captive-born macaques in breeding might need to explore new and revised husbandry strategies that address potential developmental and behavioral differences of captive-born breeders.
