Abstract

Egg has valuable nutrients however; these nutrients may be affected by many factors. In this study, it was aimed to determine the effects of cage type, oviposition time and egg storage period on egg quality characteristics of laying hens. A total of 410 eggs were collected from unenriched and enriched cages in the morning and in the afternoon. After the eggs were weighed, they were stored at 21oC and 20% relative humidity until the 30th day of storage. It was determined that unenriched cage eggs had higher in shell breaking strength, albumen ash and pH & lipid of yolk and lower egg weight loss, yolk index & yolk color compared with enriched cage eggs. Morning eggs had the highest egg weight loss and the lowest egg weight, yolk height and yolk diameter. Dry matter & protein of albumen and dry matter & lipid of yolk were lower, while protein of yolk was higher in the morning eggs than those in the afternoon. It was observed that the storage period was important factor for egg quality characteristics. The effect of oviposition time and storage period interaction on egg quality should not be neglected. Interactions between cage type and storage period and between oviposition time and storage period were found statistically significant for some chemical composition of albumen and yolk. It is concluded that A quality egg criteria are preserved up to 14 days at an average temperature of 21°C and 20% humidity.

Özet

Yumurta değerli besinlere sahiptir, fakat bu besinler birçok faktörden etkilenebilir. Çalışmada, yumurtacı tavuklarda kafes tipi, yumurtlama zamanı ve depolama süresinin yumurta kalite özelliklerine etkilerini belirlemek amaçlanmıştır. Zenginleştirilmemiş ve zenginleştirilmiş kafeslerden sabah ve öğleden sonra toplam 410 yumurta toplanmıştır. Yumurtalar tartıldıktan sonra depolamanın 30. gününe kadar 21oC sıcaklık ve %20 nemde depolanmıştır. Zenginleştirilmemiş kafes yumurtaları, zenginleştirilmiş kafes yumurtaları ile karşılaştırıldığında daha yüksek kabuk kırılma mukavemeti, ak kül ve sarı pH & yağ değerlerine ve daha düşük yumurta ağırlık kaybı, sarı indeksi & sarı rengine sahip olduğu belirlenmiştir. Öğleden sonraki yumurtalara kıyasla sabah yumurtalarının daha yüksek yumurta ağırlık kaybı ile daha düşük yumurta ağırlığı, sarı yüksekliği ve sarı çapına sahip olduğu gözlenmiştir. Ayrıca bu yumurtalarda ak kuru madde & protein düzeyi ile sarı kuru madde & yağ düzeyi daha düşükken, sarı protein düzeyi daha yüksektir. Depolama süresinin yumurta kalite özellikleri için önemli bir faktör olduğu gözlenmiştir. Yumurtlama zamanı ve depolama süresi etkileşiminin yumurta kalitesi üzerindeki etkisi ihmal edilmemelidir. Kafes tipi ve depolama süresi ile yumurtlama zamanı ve depolama süresi arasındaki etkileşimler ak ve sarının bazı kimyasal bileşimleri için istatistik açıdan önemli bulunmuştur. A kalitede ki yumurtada aranan kriterlerin ortalama 21 °C sıcaklıkta ve % 20 nemde 14 güne kadar korunduğu sonucuna varılmıştır.
