Investigation of Pathological Lesions and Fetal Losses in Slaughtered Cattle

Abstract

In the presented study, we aimed to investigate fetal wastage and endometritis ratio in slaughterhouses. For this aim, we examined the uterus and ovarium tissues of slaughtered cattle by using macroscopic and histopathological evaluation methods to detect pregnancy and metritis ratio. Routine histopathological processing was performed for gathered tissues. All sections were stained with hematoxylin- eosin. After staining all slides were examined under the light microscopy.  Out of the 140 cattle, 18 animals were found to be pregnant at different stages of pregnancy. No histopathological changes were observed in 62 uterus organs of 122 non-pregnant cattle and inflammatory uterine lesions were observed in different characters and intensities in 60 uterus organs. In result of this study, we detect the percentage of pregnant animals which are slaughtered is 12,8%. Besides, the percentage of female animals with no pathological lesions were found to be an obstacle to pregnancy is 44,2%. According to these findings, we were in the belief that these rates are a significant loss in terms of our local economy.

Kesime Sevk Edilen İnek Uteruslarında Hayvanların Damızlık Değerini Düşüren Patolojik Lezyonların ve Fötal Kayıpların Araştırılması

Öz

Bu çalışmada; kesime sevk edilen ineklerin, uterus organlarının makroskobik ve histopatolojik muayenelerinin yapılması, böylece gebe olarak kesime sevk edilen hayvan sayısının belirlenmesi amaçlandı. Ayrıca, toplanan örneklerde yapılacak histopatolojik mueyene ile endometritisli hayvanların, uteruslarında yangı olmayan hayvanlara oranının tespit edilmesi amaçlanmıştır. Bu amaçla dişi hayvan kesimleri rutin olarak takip edildi ve bu hayvanlara ait uterus organları toplandı. Toplanan bu organlar detaylı makroskobik ve histopatolojik muayeneden geçirildi. Tüm kesitler hematoksilen-eozin boyama yöntemi ile boyandı ve histopatolojik muayene ışık mikroskobu kullanılarak yapıldı. Toplam 140 hayvana ait uterus organlarının dış bakısında 18 (%12.8) hayvanın farklı dönemlerde gebe olduğu tespit edildi. Yine uterus organlarına yapılan makroskobik ve histopatolojik incelemeler sonucunda gebe olmayan 122 hayvana ait organların 62’ sinde herhangi patolojik bir değişiklik izlenmedi, 60’ ında ise farklı karakter ve şiddetlerde yangısal lezyonlar izlendi.  Sonuç olarak kesime sevk edilen dişi hayvanlardan gebe hayvan oranının yöremizde %12.8 olduğu, ayrıca kesilen hayvanların %44.2’ sinde gebeliğe engel teşkil edecek herhangi bir patolojik lezyona rastlanmadığı görülmüş ve bu oranların bölge hayvancılığımız açısından önemli bir kayıp olduğu kanısına varılmıştır.
