The absence of distal extremities is defined as peromelia, while the presence of a single eyeball in a single orbit on the median line or the presence of two incompletely fused eyeballs is defined as cyclopia. While cyclopia is common in calves, peromelia is rare. In the present report, it was determined that a male Simmental calf born with a case of dystocia had a typical case of cyclopia. However, the changes were not limited to the eyeball but arhinia, hypoplastic maxillary bone, upward curved jaw and peromelia were observed. In the literature review, no case report was found in which cyclopia and peromelia were seen together, and in this respect, it is thought to be different from other case reports. Genetic and environmental factors and their combinations cause congenital anomalies. The main cause of cyclopia in sheep is reported to be the Verratum plant. It is unlikely that this plant was responsible for the calf anomaly in the presented case. It is thought that this situation is related to the formation of pregnancies with the bull, which has been used for a long time in the enterprise, and the consequent inbreeding caused this.

Simmental Bir Buzağıda Cyclopia ve Promelia Olgusu

Öz

Distal ekstremitelerin yokluğu peromeli, tek göz küresinin median çizgi üzerinde tek yörüngede bulunması veya iki göz küresinin tam olarak kaynaşmamış olması siklopi olarak tanımlanır. Buzağılarda siklopi sık görülürken, peromelia nadirdir. Sunulan raporda distosi olgusu ile dünyaya gelen erkek bir Simental buzağının tipik bir siklopi olgusuna sahip olduğu belirlendi. Ancak değişiklikler göz küresi ile sınırlı kalmayıp arhinya, hipoplastik maksiller kemik, yukarı doğru kıvrık çene ve peromeli gözlendi Literatür taramasında siklopi ve peromelinin birlikte görüldüğü bir olgu sunumuna rastlanılmaması bu olguyu diğerlerinden farklı kılmaktadır. Doğuştan anomaliler, genetik ve çevresel faktörlerin birleşiminden kaynaklanır. Koyunlarda siklopinin başlıca nedeninin Verratum bitkisi olduğu bildirilmektedir. Sunulan vakadaki baldır anomalisinden bu bitkinin sorumlu olması olası değildir. Bu durumun ortaya çıkmasında işletmedeki boğanın uzun süre çiftleştimede kullanımı sonucu gebelik oluşumu ve buna bağlı akrabalı yetiştirme ile ilgili olduğu düşünülmektedir.
