title: Reproductive parameters and life-history variables in captive golden-bellied mangabeys (Cercocebus agilis chrysogaster).
abstract: An understanding of the reproductive physiology of captive primates is vital for their successful management. We report on reproductive parameters and life-history variables collected at the Sacramento Zoo for five female golden-bellied mangabeys (Cercocebus agilis chrysogaster) over a 7-year period. For each female, we collected data on their sexual skins, menses, gestation, and other pregnancy-related factors, such as postconception bleeding and swelling. We used these data to estimate life-history variables, such as age at onset of estrus, menses, and conception, as well as the duration of intervals between births, and between parturition and the resumption of cycling. Cercocebus agilis chrysogaster is comparable to other Cercocebus species in terms of reproductive parameters, although variability is exhibited within and among female subjects. In some cases, it appears that stressful incidents altered cycle length or halted cycling altogether. We suggest the use of husbandry practices that include consistent data collection to enhance regularity in reproductive cycles, and maximize captive breeding success for this rare species.
