Abstract

An analysis of 512 pregnancies that occurred over a 9-year period in a laboratory colony of squirrel monkeys (Saimiri sciureus) revealed yeat-to-year variation in pregnancy outcome and birth weight. Although births occurred through the year, 72% were between May and August. Male infants outnumbered females 1.31:1 and were heavier at birth. Birth weight was an important determinant of infant survival. Maternal age did not affect birth weight in this sample. Dams present in the colony for long periods tended to deliver smaller infants with a decreased potential for survival. Reproductive causes contributed to 48% of the maternal deaths. Homorrhage at or near the time of delivery was the principle cause of maternal reproductive mortality. Most neonatal deaths were attributable to accident, prematurity or trauma.

摘要

对松鼠猴（松鼠猴属）实验室群体在9年期间发生的512次怀孕进行的分析显示，怀孕结果和出生体重存在逐年变化。尽管全年都有分娩，但72%发生在5月至8月之间。雄性婴儿数量超过雌性，比例为1.31:1，且出生时体重更重。出生体重是婴儿存活的重要决定因素。在这个样本中，母体年龄不影响出生体重。长期存在于群体中的母猴往往产下较小的婴儿，存活潜力降低。生殖原因导致了48%的母体死亡。分娩时或分娩前后的出血是母体生殖死亡的主要原因。大多数新生儿死亡归因于意外、早产或创伤。
