Ankara Tavukçuluk Araştırma İstasyonu Tavukçuluk Araştırma Enstitüsünde Geliştirilen Beyaz Yumurtacı Ebeveynlerin Çeşitli Verim Özellikleri

Abstract

Ankara Tavukçuluk Araştırma Enstitüsünde bulunan Beyaz yumurtacı saf hatlardan elde edilen 4 ebeveyn (Blue Line, Maroon Line, Blue Line x Maroon Line ve Maroon Line x Blue Line) genotipinin her birinden yaklaşık 400'er adet piliç 64 hafta sonuna kadar verim testine tabi tutulmuştur. Bu ebeveynlerin cinsi olgunluk yaşı sırasıyla 141.5, 146.1, 142.3, 142.7 gün, cinsi olgunluk ağırlığı 1364.2 1405.8, 1389.2, 1375.6 g, yumurta verimi 258.4, 252.9, 261.3, 254.7 adet, yumurta ağırlığı 57.6, 58.3, 59.1, 59.4 g, şekil indeksi % 76.3, 75.6, 76.1, 75.7, damızlık yumurta oranı % 81.66, 84.99, 85.05, 86.2 ortalama günlük yem tüketimi 105.81, 105.97, 109.17, 106.91 olarak bulunmuştur. Bu özellikler bakımından ebevenyler arasındaki farklılık önemlidir (P<0.01). Verim dönemi yaşama gücü ise (%) 93.61, 95.72, 93.59 94.46 olup ebeveynler arasında farklılık bulunmadığı tespit edilmiştir (P>0.05)

Various Production Characteristics of White Layer Breeders Developed in the Poultry Research Institute

Abstract

By taking 400 each hens from each of 4 parent genotypes Blue Line, Maroon Line, Blue Line x Maroon Line ve Maroon Line x Blue Line that were derived from pure-line breeders existing in Poultry Research Institute by hybridization of them in various combination their various production characteristics up to end of 64 weeks of age have been determined. In parent genotypes; average daily feed consumption, 105.81, 105.97, 109.17, 106.91 gram; age of sexual maturity 141.5, 146.1, 142.3, 142.7 day; body weight at sexual maturity 1364.2, 1405.8, 1389.2, 1375.6 gram; egg production, 258.4, 252.9, 261.3 , 254.7 egg/per capita; egg weight, 57.6, 58.3, 59.1, 59.4 gram; egg shape index , 76.3, 75.6, 76.1, 75.7, and the rate of eggs for breeding purpose, (%) 81.66, 84.99, 85.05, 86.2 have been found, respectively. Among the parent genotypes Blue Line, Maroon Line, Blue Line x Maroon Line ve Maroon Line x Blue Line of it has been determined that there have been significant level of differences in terms of the whole traits asserted (P<0.01). Survival rates, (%) 91.84, 93.86, 96.32, 90.66, 91.34, 87.67, 96.49, 94.92 have been found, respectively. In terms of the rate of eggs for survival rates, no significant difference has been found among parent genotypes (P>0.05).
