Bu çal›flmada 57 adet inek puerperal dönemde (15-45. günler aras›) ve erken gebelik döneminde (8-58.günler aras›) on günlük aral›kla klinik ve ultrasonografik (US) yöntemlerle kontrol edildi. US ile p.ins. 8. günde 0,5-1,5 cm aras›nda de¤iflen nidasyon alanlar› saptanm›fl (n=53) ve 40 hayvanda (%70,2) bu alanlar›n geliflimi gebeli¤in 58. gününe de¤in izlenmifltir. Di¤er 13 inekte (%22,8) erken (18.gün) ve 28. günden bafllayarak geç embriyonik-fötal ölümler US arac›l›¤› ile saptand›. Post inseminasyon (p.ins.) 8. günden bafllayarak nidasyon alanlar› görülmeyen 4 (%7,0) hayvan›n US ile gebe olmad›¤› saptand›. Erken embriyonik ölümlerde östrus'un gecikti¤i, corpus luteum çaplar›n›n küçük oldu¤u (1,10-1,46 cm), geç embriyonik-fötalölümlerde ise bu bulgulara ek olarak yavru keselerinin bütünlü¤ünün bozuldu¤u, kar tanesi fleklinde da¤›ld›¤› ve ekojen bölgenindarald›¤› gözlenmifltir. Gebe hayvanlar ve embriyonik ölümlerde progesteron de¤erlerinin corpora luteiler'in ortalama çaplar›na uygun seyrettikleri ortaya konmufltur. Kavite içeren corpus luteumlar'›n gebeli¤i etkilemedi¤i belirlenmifltir.US ile cornu uteriler'in ölçümleri sonucu tohumlamadan sonra gebe kalan ve kalmayan inekler aras›nda ortalama 0,6 cm'lik önemli bir fark bulunmufltur (p<0,01). Bu hayvanlar aras›nda follikül büyüklü¤ü bak›m›ndan herhangi bir farkl›l›k elde edilememifltir. US arac›l›¤› ile folliküler ve luteal kistler'in de birbirinden ayr›labilece¤i de saptanm›flt›r.

In this study 57 cows at the puerperal stage (between 15-45 days) and at early pregnancy period (between 8-58 days) were subjected to clinical and Ultrasonography check at 10-day intervals. On the 8 th day of post insemination (p.ins.) areas of nidation ranging from 0,5-1,5 cm were established by means of US (n=53) and on 40 animals (70,2%) the development of these areas were followed until the 58th day of pregnancy. In the other 13 cows (22,8%), begining from early embriyonic featal deaths (18) days and late embriyonic featal deaths (28 days) were established ultrasonographycally. 4 animals (7,0%) that no areas of nidation were observed, from day 8 post insemination (p.ins.), were determined not be pregnant. In early embryonic deaths it has been observed that , oestrus was delayed, the diameter of corpus luteum were small (1,10-1,46 cm) while in late embryonic death in addition to these findings it has been observed that the wholeness of featal sacks were disordered, scattered in the form of snow flakes, and that the echogenic area narrowed. It has been found aut that the progesteron values followed in compatible with average diameter of corpora lutea in pregnant animals and embriyonic deaths. It has been determined that corpora lutea containing cavities did not affect pregnancy. A significant difference an average of 0,6 cm was found between the cows that became pregnant after insemination and there that did not become pregnant as result of assay of cornu uteri through US (p
