Effect of Hen Age on Some Egg Quality Characteristics of Pheasants (P. colchicus)

Effect of Hen Age on Some Egg Quality Characteristics of Pheasants (P. colchicus) ABSTRACT In this study, it was aimed to determine the effects of hen age of pheasants on egg quality characteristics. Totally 48 female pheasants in 37 week of ages were used ready for egg production. Egg quality characteristics of 200 pheasant eggs obtained from 41-51 week ages were investigated. It was determined that effects of hen age on egg weight, shape index, yolk index, albumen index, shell weight, shell thickness, membrane weight, membrane thickness, Haugh unite, albumen weight and yolk weight were statistically important (P<0.05). It was determined that shell weight and thickness, membrane weight, Haugh Unite and yolk weight decreased together with the age while albumen weight increased together with the age (P<0.05). As a result of the study, it was concluded that further investigations are needed to be made inquire the other factors affecting pheasant egg characteristics. Sulunlerde Anac Yasinin Bazi Yumurta Kalite Ozellikleri Uzerine Etkisi Ozet Bu calismada, sulunlerde anac yasinin yumurta kalitesi ozelliklerine olan etkilerinin belirlenmesi amaclanmistir. 37 haftalik yasta toplam 48 disi sulun, yumurta uretimi icin kullanildi. Yaslari 41-51 haftalik olan sulunlerden elde edilen 200 adet sulun yumurtasinin yumurta kalite ozellikleri arastirildi. Tavuklarin yumurta agirligi, sekil indeksi, yumurta sarisi indeksi, albumin indeksi, kabuk agirligi, kabuk kalinligi, zar agirligi, zar kalinligi, Haugh Unit degeri, albumin agirligi ve yumurta sarisi agirligi uzerine etkilerinin istatistiksel olarak onemli oldugu belirlenmistir (P <0.05). Kabuk agirligi ve kalinligi, zar agirligi, Haugh Unite ve yumurta sarisi agirliginin yasla birlikte azaldigi, albumin agirliginin da yasla birlikte arttigi belirlenmistir (P <0.05). Arastirma sonucunda sulun yumurtasi ozelliklerine etki eden diger faktorleri arastirmak icin daha fazla arastirmaya ihtiyac oldugu sonucuna varilmistir.
