Abstract
Bu çalışmada ileri yaşlı kahverengi yumurtacı tavuklarda farklı yönetimsel faktörlerin yumurta verimi ve kalite özelliklerine etkisini belirlemek amacı ile iki ayrı deneme gerçekleştirilmiştir. Çalışmada 104 haftalık yaşta 360 adet Lohman Brown genotipi tavuk kullanılmış ve 14 haftalık süre ile test edilmiştir. I. Denemede; kafes tavukları için ticari ve işletme koşullarında hazırlanan iki farklı rasyonun; II. Denemede kafes ve serbest dolaşımlı sistemin yumurta verimi ve kalitesine etkileri incelenmiştir. Rasyon çeşidinin kırık-çatlak yumurta oranı ve günde tavuk başına yem tüketimi, barınak tipinin yumurta verimi, kırık-çatlak yumurta oranı, günde tavuk başına yem tüketimi ve yaşama gücü üzerine etkileri önemli bulunmuştur. Sonuç olarak, ileri yaşlı kahverengi yumurtacı tavuklarda ticari olarak hazırlanan rasyonun işletme koşullarında hazırlanan rasyona, serbest dolaşımlı sistemin kafes sistemine teknik ve ekonomik yönden üstün olduğu belirlenmiştir.
This study was made to investigate the effects of different management factors (ration and housing systems) on end-of-cycle laying performance and egg quality in Brown-egg laying hens. A total of 360 hens of 104 weeks of age (Lohman Brown) were tested up to 118 weeks of age. Two layer rations (commercial and hand-made) and two housing systems (cage and free-range) were used in experiment I and II. Significant differences were detected among the feeding groups in percentage of cracked eggs and feed consumption per hen. The egg production ratio, cracked egg ratio, feed consumption per hen and survival rate of hens raised free-range was significantly better than hens raised cage system. As a result; the technical and economical end-of-cycle laying performance of brownegg laying hens feeding commercial ration and housed free-range were found superior compare to their counterparts.
