Abstract

Sunulan çalışmanın amacı ineklerde östrus siklusunun farklı günlerinde elde edilen ekotekstür parametreleri kullanılarak uterusta meydana gelebilecek olası değişikliklerin incelenmesidir. Çalışmada Erzurum’da özel bir işletmede bulunan, klinik veya subklinik endometritis belirtisi gözlenmeyen, 1. laktasyondaki 42 adet inek kullanıldı. Östrus gözlenen ineklerde östrus günü (0. gün), siklusun farklı günlerinde (4, 12, 16, 18, 21. günler) ultrasonografik görüntüler alındı. Uterus endometriyumundan alınan görüntülerdeki ortalama gri değer (MGL), homojenite (HOM) ve kontrast (CON) parametreleri bilgisayar destekli görüntü analiz programıyla incelendi. İneklerde östrus siklusunun farklı günlerindeki ortalama ekotekstür parametreleri; MGL için 68.43±0.55, HOM için 0.080±0.001, ve CON için 54.23±0.37 olarak bulundu. Ortalama gri değer ile HOM arasında negatif, CON değerleriyle ise pozitif bir ilişki olduğu saptanırken, HOM ve CON değerleri arasında da ise negatif bir ilişki olduğu gözlemlendi. Sonuç olarak siklusun farklı dönemlerindeki ineklerin endometriyumundan alınan görüntülerdeki MGL, HOM ve CON değerleri arasında istatistiksel fark saptanmadı. Siklus folliküler ve luteal dönem olarak değerlendirildiğinde ise; MGL değerlerinin siklusun folliküler fazında yüksek, luteal fazında ise düşük seyrettiği homojenite değerlerinin ise foliküler fazda düşük, luteal fazda ise yüksek seyrettiği görüldü.

Investigation of Changes in The Uterine Echogenicity of Cows During Oestrus Cycle in Cows

Abstract

The aim of the present study is to examine possible changes that may occur in the uterus by using the echotexture parameters obtained on different days of the oestrus cycle in cows. In the study, 42 cows in the first lactation, with no clinical or subclinical endometritis symptoms, in a private farm in Erzurum were used. Ultrasonographic images were taken on the oestrus day (0thday) and on different days of the cycle (4, 12, 16, 18, 21) in cows with oestrus. The mean gray value (MGL), homogeneity (HOM), and contrast (CON) parameters in the images taken from the uterine endometrium were examined with a computer-assisted image analysis program. Average echotexture parameters on the different days of the estrus cycle in cows were detected as 68.43±0.55 for MGL, 0.080±0.001 for HOM, and 54.23±0.37 for CON. There was a negative relationship between the mean gray value and HOM, and a positive relationship with the CON values, while a negative relationship was observed between the HOM and CON values. As a result, no statistical difference was found between MGL, HOM and CON values in the images taken from the endometrium of cows in different periods of the cycle. When the cycle is evaluated as follicular and luteal period; It was observed that MGL values were high in the follicular phase of the cycle and low in the luteal phase, while homogeneity values were low in the follicular phase and high in the luteal phase.
