Ankara Tavukçuluk Araştırma Enstitüsünde Geliştirilen Kahverengi Yumurtacı Ebeveyn ve Hibritlerin Çeşitli Verim Özellikleri

Abstract

Bu proje, Ankara Tavukçuluk Araştırma Enstitüsünde bulunan saf hatlardan elde edilen ebeveyn ve bunların hibritlerinin çeşitli verim özelliklerinin tespiti amacıyla yapılmıştır. Projede 4 ebeveyn (Barred Rock I, Barred Rock II, Colombian Rock x Line 54, Line 54 x Colombian Rock ) ve 4 hibrit (Rhode Island Red I x Barred Rock I , Rhode Island Red II x Barred Rock II , Rhode Island Red II x Line 54, Rhode Island Red I x Colombian Rock) genotipleri ile çalışılmıştır. Bu genotiplerde cinsi olgunluk yaşı ve ağırlığı, ilk on yumurta ağırlığı, yumurta verimi ve ağırlığı, yaşama gücü, canlı ağırlık değişimi ile dönem sonu canlı ağırlıkları tespit edilmiştir. Adı geçen genotiplerden 16 haftalık yaşta 132’ şer adet ebeveyn ve 132’şer adet hibrit olmak üzere toplam 1056 adet piliç çevre kontrollü kümesteki kafeslere yerleştirilmiş ve test 72. hafta sonunda sona erdirilmiştir. Ebeveyn genotiplerde yukarıdaki sıraya göre cinsi olgunluk yaşı; 146, 151, 146, 146 gün, cinsi olgunluk ağırlığı; 1667, 1787, 1668, 1616 gram, ilk 10 yumurta ağırlığı; 44,1, 46,8, 44,0, 41,9 gram, yumurta verimi (72 hafta) 301, 287, 290, 300 adet, yumurta ağırlığı 58,1, 61,3, 58,6, 56,1 gram, dönem sonu ( 72. hafta ) canlı ağırlık 2133, 2208, 2115, 1958 gram, tavuk dönemi yaşama gücü ( % ); 98,5, 97,7, 96,9, 96,2 olarak bulunmuştur. Hibrit genotiplerde yukarıdaki sıraya göre cinsi olgunluk yaşı; 142, 144, 146, 146 gün, cinsi olgunluk ağırlığı; 1836, 1822, 1638, 1759 gram, yumurta verimi; 312, 299, 303, 302 adet, yumurta ağırlığı; 62.5, 63.9, 60.1, 61.0 gram, dönem sonu ( 72. hafta ) canlı ağırlık; 2432, 2459, 2172, 2233 gram, , tavuk dönemi yaşama gücü ( % ) ; 96.2, 96.9, 96.9, 90.1 olarak bulunmuştur

Investigating Some Important Production Parameters Of Brown Layer Hybrid Parents And Its Hybrids, Which Are Breeding in Ankara Poultry Research Institute

Abstract

In this research, some important yields of the layer hybrid parents and its hybrids of the pure lines which have developed by Ankara Poultry research Institute, were tried to ferret out. Four parrent genotypes (Barred Rock I, Barred Rock II, Colombian Rock x Line 54, Line 54 x Colombian Rock ) and four hybrid genotypes (Rhode Island Red I x Barred Rock I , Rhode Island Red II x Barred Rock II , Rhode Island Red II x Line 54, Rhode Island Red I x Colombian Rock) were studied. The age of first egg, first ten egg’s weight, total egg production, average egg weight, livability, live weight changes and live weight at the end of the production period of these genoypes were examinated. Total 1056 birds were bred in the cages of an environmentally controlled poultry house from 132 parent and 132 hybrids at each afore mentioned genotypes at the age of 16 weeks.Reseach ended at the age of 72 weeks. In the same order given above for the parent genotypes; the age of first egg was founded 146, 151, 146, 146 days; live weight at the age of first egg was founded 1667,1787,1668,1616 grams, first ten egg’s weight was founded 44.1, 46.8, 44.0, 41.9 grams ; total egg production was founded 301, 287, 290, 300 units, egg weight was founded 58.1, 61.3, 58.6, 56.1 grams , live weight at the end of the production period ( 72 weeks ) was founded 2133, 2208, 2115, 1958 grams, production period livability was founded 98.5, 97.7, 96.9, 96.2 %. In the same order given above for the hybrid genotypes; the age of first egg was founded 142, 144, 146, 146 days; live weight at the age of first egg was founded 1836, 1822, 1638, 1759 grams; total egg production was founded 312, 299, 303, 302 units, egg weight was founded 62.5, 63.9, 60.1, 61.0 grams; live weight at the end of the production period ( 72 weeks ) was founded 2432, 2459, 2172, 2233 grams; production period livability was founded 98.5, 97.7, 96.9, 96.2 %.
