Abstract

Ultrasonografi veteriner reprodüksiyonunda keçileri de içeren türlerde sıklıkla kullanılan bir tekniktir. Transrektal yolla

keçilerde gebelik çiftleşmeden sonra en erken 16.günde saptanabilir. Ama keçilerde erken embriyonik ölümlerden transrektal

muayene için dolayı gebeliğin 32-34. günlerine kadar beklenilmesi önerilir. Keçilerde transabdominal ultrasonografi (TA) ile gebelik

teşhisi gebeliğin 2. yarısından sonra tercih edilebilir çünkü bu dönemden sonra gebe uterus kranio-ventrale doğru inmeye başlar

ve transrektal ultrasonografi bu dönemde yavru kısımlarının ayırt edilmesinde yetersiz kalırken gebelik yine bu yolla da teşhis

edilebilir. Keçilerde 3.5 mHz TA ultrasonografi ile içi sıvı dolu keseler yaklaşık 25 gün ve sonrasında rahatlıkla gözlemlenmiştir.

Transvaginal ultrasonografi taraması keçilerde çiftleşme sonrasında yaklaşık 7.haftada erken gebeliğin teşhisine izin verebilir.

Sonuç olarak, TR, TA’ya göre gebeliği 4-5 gün önceden teşhis etmeye izin verdiği için daha iyi olarak düşünülebilir. Gebelik,

TR muayenesinde de teşhis edilebilir fakat gebe uterus kranio-ventrale indiğinden fötusun kısımlarının ayırt edilmesi güçtür. Bu

derlemede, keçilerde gebeliğin saptanmasında ultrasonografinin yolları tartışıldı.

Pregnancy Diagnosis in Goats By Ultrasonography

Abstract

Ultrasonography is a technique commonly used in veterinary reproduction in species including goats. Pregnancy in

goats can be detected as early as the 16th day post-breeding via transrectal way. However, because of the early embryonic losses,

it is recommended to delay the transrectal examination until days 32-34 of gestation. Transabdominal (TA) ultrasonography for

pregnancy diagnosis in goats can be preferred from the second trimester on because after this period the gravid uterus starts to

descend into the cranio-ventral direction. The transrectal (TR) ultrasonography in this period becomes inadequate to distinguish

the parts of the foetus. But it can still detect the pregnancy. By using the TA ultrasonography with 3.5mHz, fluid filled vesicles were

observed approximately from 25 day onwards in goats. Transvaginal ultrasound scanning can be an early pregnancy diagnosis

in goats approximately 7 weeks post mating. In conclusion, the TR can be considered superior to TA in small ruminants to detect

the pregnancy as it leads 4-5 days earlier diagnosis in the TR way than the TA way. Pregnancy can be detected, using the TR

ultrasonography after second trimester; but, as the gravid uterus descends cranio-ventral direction, it is difficult to distinguish the

parts of the foetus. In this review, the ways of ultrasonography for pregnancy determination in goats were discussed.
