Bu çalýþma, koyunlarda transabdominal ve transrektal ultrasonografi kullanarak gebelik süresince plasentom geliþimini belirlemek,plasentom çaplarý ile gebelik yaþý arasýndaki iliþkiyi tespit etmek amacýyla yapýlmýþtýr. Çalýþmada B Mode, linear array, 5,0-7,5 MHzrektal transduceri olan ultrason kullanýldý. Muayenelere çiftleþme sonrasýndaki 26 ile 28. günlerde baþlandý. Gebe olan 50 koyun çalýþmayadahil edildi. Bu koyunlarda ultrasonografik incelemeler birer hafta arayla olmak üzere doðuma kadar tekrarlandý. Haftalýk olarak tekrarlananmuayenelerde 5 plasentomun çapý ölçülerek kaydedildi ve ortalamasý hesaplandý. Gebe olarak tespit edilen 50 koyundan 44 tanesitekiz, 6 tanesi ikiz gebeliðe sahipti. Plasentomlar gebeliðin 4. haftasýndan itibaren görülmeye baþlandý. Plasentomlar gebeliðin ilkhaftalarýnda hýzlý bir þekilde geliþti ve gebeliðin 11. haftasýnda en büyük çapa (3,41±0,04 cm) ulaþtý. Plasentom çaplarý gebeliðin ilkyarýsýnda artarken gebeliðin ikinci yarýsýnda tedricen azalmaya baþladý ve doðuma yakýn dönemde 1,73±0,18 cmye kadar küçüldü.Koyunlarda gebelik yaþý ve plasentom çapý arasýnda zayýf bir iliþki bulundu (regression katsayýsý, r = 0,540). Plasentom çaplarý bakýmýndantekiz ve ikiz gebeliðe sahip koyunlar arasýnda herhangi bir fark tespit edilmedi (P > 0,05). Sonuç olarak, koyunlarda plasentom geliþiminingebeliðin 4. haftasýndan doðuma kadarki döneme kadar ultrasonografik muayenelerle kolaylýkla takip edilebileceði, bununla birliktekoyunlarda plasentom çapý ve gebelik yaþý arasýndaki zayýf iliþkiden dolayý plasentom çaplarýna göre gebelik yaþýnýn belirlenemeyeceðikanýsýna varýldý

Determination of Placentome Development and Gestational Age by Ultrasonographic Measurement of Placentomes in Ewes

The objective of this study was to determine the placentome development during pregnancy and the correlation betweenplacentome diameter and gestational age using transabdominal and transrectal ultrasonography in ewes. A B-mode, linear array,ultrasonography with 5,0-7,5 MHz rectal transducer was used in this study. Examinations were commenced at days 26 to 28 post mating.In this study, fifty pregnant ewes were used. Ultrasonographic examination was performed weekly until birth. Diameters of five placentomeswere measured in weekly examinations and then mean diameter was calculated. Among the fifty pregnant ewes, 44 had single pregnancywhile six ewes had twin pregnancy. Placentomes were seen since 4th week of pregnancy. Placentomes developed fast in the first weeksof pregnancy and reached maximum diameter in 11th week (3,41±0,04 cm). Diameter of placentomes increased during the first weeksof pregnancy but decreased in the second half and decreased to 1,73±0,18 cm before birth. A weak correlation was found betweengestational age and diameter of placentome in ewes (regression coefficient, r = 0,540). There was no difference between placentomediameters between single and twin pregnancies (P > 0,05). As a result, placentome development in ewes during pregnancy can easilybe determined from 4th week of gestation to birth. Besides, because of weak correlation between placentome diameter and gestationalage in ewes, it is concluded that, gestational age cannot be determined from diameter of placentome
