Analysis of Reproductive Data in a Breeding Colony of African Green Monkeys

Abstract

In a breeding colony of Cercopithecus aethiops aethiops and C. a. pygerythrus, containing 109 feral females which have lived in the colony for at least one year, 89% have given birth, and 92% have become pregnant. There were 221 pregnancies and 186 live births with multiple births and no evidence for a birth season. A net estimated reproductivity rate indicates 180 sexually mature females would produce over 100 offspring per year.
