Abstract

This experiment was performed to study egg quality characteristics of a Turkish local breed Denizli, and a commercial layer flock. The investigation was started when the birds were 28 weeks old, and the experiment repeated four times at four-weeks-intervals. Egg weight, and egg quality traits including shape index, breaking strength, shell thickness, yolk index, white index, haugh unit and yolk colour were studied. The ANOVA indicated a statistically significant differences (P<0.001) among the repeated trials for all egg characteristics except white index in commercial flock in both genotypes. Shape index, shell thickness, white index and Haugh unit were found to be higher in commercial layer (P<0.01). On the other hand, breaking strength and yolk colour were found to be higher in Denizli fowl (P<0.001). No significant differences were detected in yolk index between two genotypes. However, the egg quality characteristics found in Denizli fowl were within the limits of standard figures suggested for hen eggs. It was concluded that Denizli fowl has potential to be improve as enough variation were observed in respect of egg quality traits in the study. In addition, this breed may be a good genetic source for improving other breeds.

Özet

Bu arastırmada Denizli ve ticari yumurtacı tavuk sürüsünde yumurta kalite özellikleri incelenmistir. Sürü yası 28 hafta iken yumurtalar incelenmeye baslanmıs ve 4 hafta aralıklarla üst üste 4 dönem halinde yapılmıstır. Her iki genotipte yumurta agırlıgı ile sekil indeksi, kırılma direnci, kabuk kalınlıgı, sarı indeksi, ak indeksi, haugh birimi gibi yumurta kalitesi özellikleri ile sarı rengi özelligi incelenmistir. Yapılan varyans analizi sonucunda ticari yumurtacılarda ak indeksi hariç her iki genotipe ait tüm özellikler bakımından tekrarlanan uygulamalar arası farklılık önemli (P<0.001) bulunmustur. Sekil indeksi, kabuk kalınlıgı, ak indeksi ve haugh birimi ortalama degerleri ticari genotipte (P<0.01), kırılma direnci ve sarı rengi degerleri ise Denizli genotipinde (P<0.001) daha yüksek bulunmustur. Sarı indeksi bakımından genotipler arası fark önemsiz bulunmustur. Bununla birlikte Denizli genotipi ile ilgili elde edilen degerler bu özellikler için belirlenen degerlerin sınırı içinde bulunmustur. Sonuç olarak, Denizli tavukları arasında yumurtanın önemli kalite özellikleri bakımından yüksek varyasyon bulundugu ve bu durumdan yararlanarak Denizli genotipinde yapılacak ıslah çalısması ile bu özelliklerin ticari genotipte elde edilen özelliklere yaklastırılabilecegi ayrıca baska tavuk genotiplerinin ıslahında da Denizli genotipinden yararlanılabilecegi anlasılmıstır.
