Abstract
The aim of this study was to determine the application of transabdominal ultrasonography in estimating gestational age in Yankasa ewes through the measurement of crown-rump length (CRL), bi-parietal diameter (BPD) and femoral length (FL). Fifteen (15) ewes were first oestrus-synchronized and mated to establish pregnancy. Transabdominal ultrasonography, using a real time B-mode ultrasound scanner, was carried out on weekly basis to determine gestation and estimate gestational age by measurement of CRL, BPD and FL, using real time B-mode ultrasound scanner. The relationships between gestational age and each of the parameters were plotted as linear regression and expressed as a straight line equation. Results obtained clearly demonstrated that CRL, BPD and FL were significantly (P
