Serial ultrasonic measurement of the biparietal diameter is an unsatisfactory means of detecting the small-for-gestational age (SGA) fetus in twin pregnancies. A new two-stage ultrasound examination schedule, highly effective in detecting the SGA singleton fetus, has been evaluated prospectively in 31 twin pregnancies. The schedule comprises ultrasonic assessment of gestational age in early pregnancy, followed by measurement of the product of the crown–rump length and trunk area of both fetuses at 34–36 weeks. All Nineteen SGA twin fetuses were detected using this schedule; the technique offers several other advantages over serial biparietal cephalometry.

The objective of this study was to predict gestational age of Osmanabadi goats by realtime ultrasonography using measurements of Crown Rump Length (CRL). CRL was measured in 15 Osmanabadi goats, by transabdominal ultrasonography carried out on days 35, 42, 49, 56, 63 and 70 of gestation, those became pregnant after oestrus detection and natural mating following oestrus synchronization in 30 does using double PGF2α injections 11 days apart. Gestational age was calculated by using gestational equations derived from the linear regression analysis. Results clearly demonstrated that biometric parameter CRL was significantly (P ios less than 0.01) correlated with gestational age (r= 0.988) and was a reliable index to predict gestational age in Osmanabadi goats.
