Gross appearance of the chicken unfertilized germinal disc

Sürü döllülüğü taze yumurtadaki germinal diskin farklı görünümüne göre belirlenebilir. Bu çalışmada; genç kahverengi yumurtacı sürüden elde edilen taze dölsüz yumurtalardaki germinal disk farklılıklarını ve dağılım frekanslarını belirlemek amaçlan¬mıştır. Çalışmada toplam 354 yumurta incelenmiştir. Yumurtalar dölsüz germinal disk görünümüne göre A, B, C, D, E ve F olmak üzere 6 farklı şekilde sınıflandırılmıştır. Sonuç olarak toplam yumurtalar içinde en yüksek oranda A şekline (%31.9) ve en düşük oranda da C şekline (%6.5) rastlanmıştır.

Dölsüz tavuk germinal diskinin görünümü

Flock fertility could be determined by different appearances of germinal disc in fresh egg. The aim of this study was to determine the differences and the frequency of distributions in the appearance of germinal disc in fresh unfertile eggs coming from a young virgin brown layer flock. In this study a total of 354 eggs was examined. Six categories of unfertile germinal disc (UGD) were defined based on their appearance as A, B, C, D, E and F. As a conclusion, in total eggs, type A (31.9%) was the highest and type C was the lowest (6.5%) in frequency.
