This paper describes usefulness of the ultrasonographical device (USD) for the diagnosis of pregnancy and the observation of fetal growth in the squirrel monkeys (Saimiri sciureus) conceived under group breeding conditions. Pregnancy was diagnosed on the basis of the detection of gestational sac (GS) in the uterus. The GS was first detected 127 +/- 10 days before delivery. The heart beat of embryo was detected around 114 days before delivery. It was able to judge conditions of fetal growth by measuring the size of GS and the biparietal diameter. No difference in uterine size between nonpregnant and pregnant animals was observed 135 days before delivery.
本文描述了超声设备（USD）在诊断松鼠猴（Saimiri sciureus）在群体饲养条件下受孕后的妊娠情况及观察胎儿生长方面的作用。妊娠是根据子宫内妊娠囊（GS）的检测来诊断的。妊娠囊最早在分娩前127±10天被检测到。胚胎心跳在分娩前约114天被检测到。通过测量妊娠囊大小和双顶径能够判断胎儿生长状况。在分娩前135天，未观察到未孕和怀孕动物子宫大小有差异。
