Growth and some period yield characteristics of Denizli x Leghorn crosses $(F_2)$

Amaç: Bu araştırmada, Denizli x Leghorn ve F2 populas-yonlarının çıkım ağırlığı, büyüme ve verim dönemine ait canlı ağırlıkları, yumurta ağırlığı ve özgül ağırlıklarının belirlenmesi amaçlamıştır.Gereç ve Yöntem: Temel populasyonda 10 Denizli horozu ve 30 Leghorn tavuk kullanılmıştır. İlk generasyonda (FJ, 15 erkek, 68 dişi elde edilmiştir. İkinci generasyonda (F2) ise 475 erkek ve 451 dişi üzerinde 32. haftaya kadar canlı ağırlık ve yumurta verimleri incelenmiştir.Bulgular: F2 populasyonunda dişiler yumurtaya girdikten sonra 180 günlük dönemde, yumurta sayıları ve yüzdeleri 99.61 adet ve %56.21 olarak bulundu. Çıkım ağırlıkları Ft ve F2 populasyonlarında sırası ile 40.94 ve 30.80 g olarak bulundu. Büyüme döneminde her iki generasyonda canlı ağırlıklar arasında önemli farklılıklar tespit edildi (p

Denizli x Leghorn melezi $(F_2)$ tavuklarda büyüme ve bazı dönem verim özellikleri

Aim: This study was carried out to determine some production characteristics of Fx and F2 Denizli x Leghorn populations including hatching weight, growth performance, live weights of the growing period, egg gravity and egg weight.Material and Methods: Ten Denizli roosters and 30 Leghorn hens were used for generation of the base population. In the first generation (FJ, 15 males and 68 females were produced. A total of 475 males and 451 females were produced in the second generation (FJ, and whose production data were evaluated based on the 32 weeks of periods.Results: In F2 population, numbers and percentages of egg yield were found to be 99.61 and 56.21% in the first 180-day period. Hatching weights were determined as 40.94 and 30.80 g in Fx and F2 generations, respectively. Significant differences were observed in weights of Ft and F2 animals at the growing period (p
