摘要

本研究的目的是通过测量羊羊的冠臀长(CRL)、双顶径(BPD)和股长(FL)，确定经腹超声在羊羊胎龄估计中的应用。15只母羊首先与发情期同步，并进行交配以建立妊娠。每周行经腹超声实时b超扫描，通过实时b超扫描测量CRL、BPD和FL来确定妊娠和估计胎龄。将胎龄与各参数之间的关系绘制成线性回归图，并用直线方程表示。结果清楚地表明，CRL、BPD和FL显著(P

Ultrasonographic Determination of Gestational Age in Yankasa Ewes

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
