This experiment includes 228 local Awassi ewes between 2 to 5 yearsold. The aim of this experiment was to estimate the fetal age bymeasurement of transthoracic, transabdominal, cotyledon length and widthduring different period of gestation by using 5MHz real-timeultrasonography. Linear, quadratic and cubic equations were described,which adjust the relationship between the gestation age and each oftransthoracic, transabdominal, cotyledon length and width. Results indicatedthat the quadratic equations of transthoracic and transabdominal were thebest equations; while the cubic equations of each of the cotyledon length andwidth were the best equations to estimate the fetal age
