GEÇ EMBRİYONAL ve ERKEN FÖTAL DÖNEMDE KONYA MERİNOSU KOYUNLARDA GEBELİK TANISI ve FÖTAL SAYIM AMACIYLA TRANSABDOMİNAL ULTRASONOGRAFİK MUAYENE TEKNİĞİNİN ETKİNLİĞİNİN DEĞERLENDİRİLMESİ

Sunulan çalýþmada Konya Merinosu ýrký koyunlarda gebelik tanýsý ve fötal sayým amacýyla geç embriyonal ve erken fötal dönemdesað (R) ve sol (L) inguinal bölgeden yapýlan transabdominal ultrasonografik muayenenin (TAUM) etkinliðinin belirlenmesi amaçlandý.Bu amaçla aþým sonrasý 34. günde transrektal ultrasonografik muayene (TRUM) ile 45 baþ tek ve 39 baþ ikiz embriyo taþýyan gebekoyun belirlendi. Toplam 84 baþ gebe koyun 34 ve 50. günlerde, RTAUM ve LTAUM yoldan farklý saatlerde muayene edilerek, bulgularTRUM ve doðum kayýtlarý ile karþýlaþtýrýldý. TRUM ve doðum kayýtlarýna göre 34. günde tekli gebelik RTAUM ve LTAUM olarak sýrasýyla % 62 (28/45) ve % 64 (29/45), 50. günde de sýrasýyla % 88 (40/45) ve % 91 (41/45) oranýnda doðru olarak belirlendi. Ýkiz gebeliklerise RTAUM ve LTAUM olarak 34. günde sýrasýyla % 33 (13/39) ve % 28 (11/39) oranýnda belirlenebilirken; 50. günde sýrasýyla % 53(21/39) ve % 46 (18/39) oranýnda doðru olarak belirlendi. Bulgulara göre gerek muayene günleri ve gerekse muayene bölgeleri arasýndaistatistiki farklýlýk görülmedi.Sonuç olarak ultrasonografik muayenede ikiz gebeliklerin ilk 50 günde RTAUM ve/veya LTAUM olarak yüksek oranda belirlenemediði;fötal sayýmýn önemli olmadýðý durumlarda ise muayenelerin 34. günden itibaren transabdominal (TA) yolla yapýlabileceði kanýsýna varýldý

Efficiency of transabdominal ultrasonography in pregnancy diagnosis during late embryonic and early fetal stages of pregnancy in Konya Merino ewes

Objective of this study was to evaluate the efficiency of location (right ingiunal region [RIR] or left ingiunal region [LIR]) oftransabdominal ultrasonography to determine pregnancy and number of embryo/fetus during late embryonic and early fetal stages ofpregnancy in Konya Merino ewes. Eighty-four ewes were diagnosed as pregnant 34 days after mating by transrectal ultasonography.Of these ewes, 45 had single embryo and 39 had twin embryos. On days 34 and 50, these ewes were again examined by RIR and LIRtransabdominal ultasonography. The results were compared with transrectal ultrasonography and lambing records. On day 34, 62 %(28/45) and 64% (29/45) of single pregnancies and 33 % (13/39) and 28 % (11/39) of twin pregnancies could be detected through RIRand LIR transabdominal ultrasonography, respectively. On day 50, 88 % (40/45) and 91 % (41/45) of single and 53 % (21/39) and 46% (18/39) of twin pregnancies were detected through RIR and LIR transabdominal ultrasonography, respectively. Data were analysedby paired simple t-test and there were no significant differences between the days 34 and 50 and locations of examinations (RIR vsLIR). In conclusion, twin pregnancies could not be diagnosed accurately by transabdominal ultasonography during the first 50 days ofpregnancy. However, in case counting the embryo/fetus is not important, pregnancy diagnosis can be performed by this method startingon day 34
