Fetal electrocardiography (FECG) in the mare has been investigated by several workers (Holmes and Darke 1968, Kanagawa and others 1967). This short paper seeks to evaluate previous work, present new findings, and provide a practical technique enabling veterinary surgeons to diagnose singleton and twin pregnancies in the latter part of pregnancy.
