Relationship between gestational age and transabdominal ultrasonographic measurements of fetus and uterus during the 2nd and 3rd trimester of gestation in cows

Conclusion Transabdominal ultrasonography is a practical and reliable method for obtaining the fetal and uterine measurements during the 2nd and 3rd trimesters of gestation. The correlation coefficients between gestational age and fetal measurements (width of trunk and heart and intercostal distance) were higher than those of uterine measurements, and the highest correlation was between heart width and gestational age in cows.
