Estimation of ewe's fetal age

Abstract

The study was performed on 95 pregnant uterus of ewes taken from Al-Falloja abattoir, fetal age were estimated by measurement of crown rump. The aim of this study was to estimate the ewe's fetal age by measurement of transthoracic, transabdominal, Head length, bipartial bone diameter, cotyledon length and cotyledon width. Linear, quadratic and cubic equations were described, which adjust the relationship between fetal age and each of transthoracic, transabdominal, Head length, bipartial bone diameter, cotyledon length and cotyledon width. The results of this study indicated that the quadratic equations of transthoracic and cotyledon width were the best equation, while the cubic equations of each of the transabdominal, Head length, bipartial bone diameter and cotyledon length were the best equations to estimate the fetal age
