Abstract
The evolution of some fetal growth indices (crown-rump length, trunk diameter,
biparietal diameter and eye orbit diameter) and different blood flow parameters (arterial pulse, peak
systolic velocity, end diastolic velocity, mean velocity, systolic velocity/diastolic velocity ratio and
pulsatility and resistance indices) of the umbilical artery of the embryos and fetuses of primiparous
pregnant goats of the Murciano-Granadina breed were analyzed by ultrasonography. Weekly ultrasonographic
sessions took place from 18- to 125-days post-mating. Fetal measures were carried
out by ultrasound B-mode. Spectral Doppler was used to study blood flow from umbilical artery.
Umbilical cord was first noticed between 32- and 35-days post-mating. However, umbilical arterial
blood flow parameters were not conclusive until 65–80 days of pregnancy. This is the first time that
a detailed study of fetal growth indices and the umbilical artery blood flow rates in fetuses from
Murciano-Granadina goats has been performed throughout virtually the entire duration of gestation,
determining the evolution of these fetal growth parameters in this breed and how the velocimetric
parameters are increasing significantly and the arterial pulse, systolic/diastolic ratio and pulsatility
and resistance indices are decreasing significantly throughout the analyzed pregnancy period.
