Popis: | The objective of the current study was to estimate whether fetal age could be accurately estimated using trans-rectal and trans-abdominal ultrasonographic measurements for placentomes diameter and Bi-parietal diameter. This experiment was carried out in the College of Veterinary Medicine in Diyala University. Twelve Multiparous cows (4-7 years old) were inseminated artificially and Serial transrectal and trans-abdominal ultrasonic examinations were done during the 7 – 13 week and during 10 -26th week of gestation, respectively. Using 5-7.5 MHz linear array transducer and also 3.5-5MHz convex transducer. Possible discrimination of placentomes and Bi-parietal diameter for the first time at the fifth and ninth week of gestation, respectively. The mean values for placentomes diameter were 7.5mm and 69 mm during 7 and 26 weeks of pregnancy, respectively, as well the placentome increased in diameter an average of 3.0028 mm per week. Besides that, the mean Bi-parietal diameter was 17.5mm and 33mm during 9 and 13 week of pregnancy, respectively. The Bi-parietal diameter was increased linearly an average of 3.620 mm per week. The obtained results revealed that using Trans-rectal ultrasonic during 3rd month of gestation to observed pregnancy and fetal organs as well as fetal viability with fast and easy during mid-gestation onward High correlations were found between different studied parameters and gestational age with high significant for both which were (R=0.97**; P |
