Abstract

The fetal electrocardiographic technique was employed with 17 Percheron mares at late gestational stages (272〜342 days of pregnancy, i.e., 2〜64 days before parturition). In all cases, fetal electrocardiograms could be recorded. The fetal heart rate during the observation period varied from 84 to 114,without any decreasing tendency with progress in fetal development. The polarity and amplitude of fetal spikes also varied with the different cases.
