This paper reports reproductive parameters for 9 female grey-cheeked mangabeys kept in a captive colony over a 17-year period. Birth seasonality has shown a consistent trend towards an autumn peak. Oestrous cycles had an average length of 31.2 days: however 'short-cycle' (29.9 days) and 'long-cycle' (37.7 days) groups could be discriminated. Gestation was 175 days, with little variability. Variability in interbirth interval is mainly due to varying length of the cycling phase preceding the next gestation, suggesting influences of social factors. All these reproductive parameters are compared to those of baboons and macaques. Some conclusions about mangabey breeding colony management are drawn.
本文报告了在一个圈养群体中饲养的9只雌性灰颊白眉猴在17年期间的繁殖参数。出生季节性呈现出一致的秋季高峰趋势。发情周期平均长度为31.2天：然而，可以区分出“短周期”（29.9天）和“长周期”（37.7天）组。妊娠期为175天，变化很小。产仔间隔的变化主要是由于下一次妊娠前周期阶段的长度不同，这表明受到社会因素的影响。所有这些繁殖参数都与狒狒和猕猴的参数进行了比较。得出了一些关于白眉猴繁殖群体管理的结论。
