Amorphus globosus in a White Galloway Cattle

Bu makale de bir Amorphus Globosus olgusu sunulmuştur. Üç yaşlı beyaz Galloway ineğin ikiz olarak şekillenen ikinci gebeliğinde bir normal buzağı ve bir de onun amorfik kusurlu ikiz partnerini doğurmuştur. Kusurlu ikiz partner, şekli hafif basık ve oval ,derisi beyaz tüylerle kaplı, 21.0x10.0x6.0 cm boyutlarında ve 1600 gr agırlığına sahibdi. Sunulan olgu, 20 cm uzunluğunda ve 2-3 cm genişliğinde göbek bağına benzer bir oluşuma sahipti. Ağız şeklinde küçük bir açıklık ve bu açıklıkta 3 adet diş ve dudaklarla birlikte küçük dil benzeri yapı görüldü. Histolojik incelemede ise olgunun sağlam bir bağ dokusu, iskelet kasları, lenf ve arteriyel damarlar, salgı bezleri ve kıkırdak dokuya benzeyen odaklardan meydana geldiği gözlemlendi. Radyolojik incelememizde net olarak alt ve üst çenenin, kuyruğa ait olduğu düşünülen küçük kemiksi yapıların ve kıkırdak dokunun varlığı tespit edildi. İnek ve boğanın ebeveynlerinin ortak olması nedeniyle olgunun akrabalı yetiştirme katsayısı %6.25 idi. Bu olgu galloway ırkı sığırda görülen ilk amorphus globosus vakası olup patolojik, histopatololojik, radyolojik bulgular ve pedigri analizini içerir.

Beyaz Galloway Sığırda Amorphus globosus Olgusu

In this article, a case of an amorphus globosus is presented. A three years old White Galloway dam gave birth in her second pregnancy a normal calf and a malformed amorphic co-twin. The malformed co-twin was slightly flattened with an ovoid covered by white hairy skin form of 21.0x10.0x6.0 cm in size and a weight of 1600 g. The present case had an umbilical cord like structure of 20 cm in length and 2-3 cm in diameter. A small opening, resembling am oral structure, contain a tongue-like structure with lips and three milk teeth. Histological examination showed a solid mass of connective tissue, skeletal muscles, lymph, arterial vessel and glandular units and focal by cartilage tissue. The radiography clearly showed lower-upper jaw, small bone similar to a tail-like-structure and a cartilage tissue. The inbreeding coefficient of the case was 6.25% due to a common ancestor on the maternal and paternal side. This is the first report on amorphus globosus in White Galloway cattle including pathological, histopathological, radiological findings and pedigree analysis.
