title: Breeding performance of a captive colony of rhesus macaques (Macaca mulatta).
abstract: For most of the 18 years recorded, fewer than 50% of the adult females gave birth in any one year. The colony, of 6 social groups, showed a clear-cut breeding season. Female parity and dominance had no effect on breeding rate, though 1st infants were born earlier in the year than 2nd-born ones. Only when females gave birth in successive years were the months of giving birth correlated. Mothers and daughters may tend to give birth closer in time within a breeding season than do other females.
