Successful breeding by captive-born Saguinus oedipus females has now been reported from several colonies, but a marked parity effect (ie, differences in infant survival with the number of litters produced) is usually observed; survival of infants of primiparous females is extremely low but increases with subsequent litters. This parity effect was not observed in the captive-born breeding females in the Oak Ridge Associated Universities colony, with survival of offspring of primiparous females at 58.6%. Two explanations are proposed for this difference: (1) pairing with a male having previous experience in siring and rearing offspring may improve infant survival for primiparous females; and (2) postponing mating to a later age may increase infant survival for primiparous mothers.
目前已有多个群体报道圈养出生的白领伶猴雌性成功繁殖，但通常会观察到明显的胎次效应（即婴儿存活率随产仔数的差异）；初产雌性的婴儿存活率极低，但会随着后续产仔数增加。橡树岭联合大学群体中圈养出生的繁殖雌性未观察到这种胎次效应，初产雌性的后代存活率为58.6%。针对这种差异提出了两种解释：（1）与有生育和养育后代经验的雄性配对可能会提高初产雌性的婴儿存活率；（2）将交配推迟到较晚年龄可能会提高初产母亲的婴儿存活率。
