Popis: | Objective: The study was designed to estimate the relationship between gestational age and transabdominal ultrasonographic measurements of fetus and uterus during the 2nd and 3rd trimester of gestation in cows. Methods: Seventeen cows with confirmed conception dates were used. The cows were examined transabdominally in standing position using the 3.5 MHz convex sector transducer of real-time ultrasonography. Measurements of length and height of placentomes, distance between uterine walls, width of trunk and heart, intercostal distance and width of umbilical cord were obtained from the ultrasonographic images by using the screen caliper software. Results: Measurements at 250 d of gestation were for placentomes length (17.87 ± 2.26) and (75.92 ± 7.76) mm, height of placentomes (13.37 ± 1.12) and (36.50 ± 3.92) mm, distance between uterine walls (71.45 ± 10.68) and (144.63 ± 7.29) mm, and width of umbilical cord (7.80 ± 0.42) and (16.41 ± 0.41) mm, width of trunk (35.67 ± 7.11) and (146.50 ± 5.34) mm, width of heart (15.10 ± 5.50) and (74.57 ± 4.20) mm, and intercostal distance (3.85 ± 0.49) and (21.79 ± 0.48) mm, respectively. All the measurements were highly significantly correlated with gestational age (P |
