Capuchin monkey ( Cebus apella ) is a new world primate that in recent years has become important in biomedical research. The purpose of this study was to establish and correlate normal fetal growth parameters with gestational age in capuchin monkeys. In seven pregnant animals serial ultrasonic assessment of gestational sac (GS), embryo/fetal greatest length (GL), biparietal diameter (BPD), thorax height (TH), and femur length (FL) were performed. Identification of the GS was possible on day 23 ± 2.8 (X ± SE). The embryo and its heartbeat was detected on day 32.7 ± 2.8, the GL being measurable thereafter. By day 45.4 ± 1.4 BPD and TH were measurable. FL could only be measured from day 70.6 ± 2.1. Predictive regression equations of gestational age (GA) were modeled with data obtained. In addition, preliminary data of fetal heart rate showed a decrease in frequency with advancing gestation.
