Özet
Bu çalışmada sarı tüy renkli japon bıldırcınlarında (Coturnix japonica) 8, 12, 16, 20, 24, 28 ve 32 haftalık yaşlarda 7 ve 14 gün süreyle depolanan kuluçkalık yumurtaların iç ve dış kalite özelliklerinin belirlenmesi amaçlanmıştır. Deneme materyali yumurtalar 8, 12, 16, 20, 24, 28 ve 32 haftalık yaş dönemlerinde sarı tüy renkli (Coturnix japonica yellow), (Y/y1) Japon bıldırcınlarından elde edilmiştir. Yumurtalar her bir kafes katında 20 adet hayvan olacak şekilde 5 kafese yerleştirilmiş toplam 100 dişi hayvandan iki gün içinde elde edilmiştir. Her bir depolama süresi (0, 7 ve 14 gün) için 75'şer, her bir yaş dönemi için 225'şer adet ve 7 yaş dönemi için (8, 12, 16, 20, 24, 28, 32 haftalık yaşlar) toplam 1575 adet yumurtaya ait dış ve iç kalite özellikleri belirlenmiştir. Depolama sırasında gerçekleşen bağıl ağırlık kaybı oranı 7 gün depolamada % 1. 63 ve 14 gün depolamada ise % 2.52 şeklinde belirlenmiş olup, bu özellik depolama sürelerine göre önemli bulunmuştur (P<0.001). Yumurta ağırlığı üzerine yaşın etkisi önemli olmuş (P<0.001) deneme başlangıcında (8. hafta) 11.67 g olan yumurta ağırlığı deneme sonunda (32. hafta) 12.15 g değerini almıştır. Yumurta eninin yumurta boyuna oranı şeklinde ifade edilen şekil indeksi 8 haftalık yaşta en yüksek (% 79.98) iken 32 haftalık yaşta en düşük (%77.33) belirlenmiş olup bu özellik üzerine yaşın etkisi önemli (P<0.001) olarak belirlenmiştir. Ak indeksi üzerine hayvan yaşı ve depolama süresi etkili olmuştur. Aynı zamanda yaş x depolama süresi arasındaki interaksiyon önemli olarak belirlenmiştir (P<0.001). Ak indeksi bakımından kontrol grubu ile 7 ve 14 günlük depolama sürelerinde sırasıyla % 10.429, % 10.029 ve % 10.015 şeklinde belirlenmiştir. Ak indeksi ilerleyen yaşla birlikte artmış, 8 haftalık yaşta % 10.039 olan bu değer 32 haftalık yaşta % 10.887 şeklinde belirlenmiştir. Haugh birimi depolama süresi (P<0.01) ve hayvan yaşından (P<0.001) etkilenmiştir. Ayrıca haugh unit değeri üzerine depolama süresi ve yaş arasındaki interaksiyon da önemlidir (P<0.001). Kontrol grubunda 90.578 olan haugh birimi, 7 ve 14 günlük depolama sürelerinde sıra ile 90.322 ve 90.348 olarak gerçekleşmiştir. Depolama işlemi yapılmayan kontrol grubunda %53.66 olarak belirlenmiş olan sarı indeks değeri 7 ( % 49.89) ve 14 (% 47.92) günlükdepolama sürelerine göre daha düşük ve uygulamalar arası farklılık önemlidir (P<0.001). Akyüzdesi üzerine depolama süresi (P<0.001) ve yaşın etkisi (P<0.001) önemli olmuştur. Ayrıcadepolama süresi ile yaş arasındaki interaksiyon da önemli olarak tespit edilmiştir (P<0.001).Ak yüzdesi kontrol, 7 ve 14 günlük depolama sürelerinde sıra ile % 55.06, % 55.63 ve %55.51 şeklindedir. Sarı yüzdesi depolama süresinden etkilenmemiş ancak yaşa göredeğişmiştirArtan depolama süresine bağlı olarak sarı indeks değeri azalmıştır. Birim yüzeyalanı başına kabuk ağırlığı (mg/cm2) depolama süresi ve hayvan yaşına göre değişmiştir (P<0.001). Gözenek sayısı üzerine hayvan yaşı etkili (P<0.001) iken depolama süresinin etkisiönemsiz olmuştur.
In this study, it was aimed to determine the internal and external quality characteristic of yellow feather-colored Japanese quail hatching eggs that were stored for 7 and 14 days at 8, 12, 16, 20, 24, 28 and 32 weeks age. The experimental material consisted of eggs obtained from yellow feather-colored (Japanese yellow) (Y/y1) Japanese quails during 8, 12, 16, 20, 24, 28 and 32 weeks age periods. The eggs were obtained in two days from 100 female animals placed in 5 cage layers with 20 animals in each cage layer. External and internal quality characteristic of 75 eggs for each storage period (0, 7 and 14 days), 225 eggs for each age period and a total of 1575 eggs for the age of 7 years (ages of 8, 12, 16, 20, 24, 28 and 32 weeks) were determined. The relative weight loss rate during storage was 1.63 % for 7 days storage and 2.52 % for 14 days storage; and this feature changed according to storage periods (P<0.001). The effect of age on egg weight was significant (P<0.001) and the egg weight which was 11.67 gr at the beginning of the experiment (8th week) was 12.15 gr at the end of the experiment (32th week). The shape index, expressed as the ratio of egg width to egg length, was found to be the highest (79.98 %) at the age of 8 weeks, and the lowest (77.33 %) at the age of 32 weeks; the effect of age on this property was determined to be significant (P<0.001). The age of animal and storage time were effective on the white index. Also the interaction between age x storage time was determined to be significant (P<0.001). In terms of white index, it was determined as 10.429 % and 10.015 % in the storage periods of 7 and 14 days with the control group, respectively. The white index increased with advancing age, this value was 10.039 % at the age of 8 weeks and 10.887 % at the age of 32 weeks. The Haugh unit was influenced by storage time e (P<0.001) and animal age (P<0.001). The interaction between storage time and age on the Haugh unit value is also important e (P<0.001). In the control group, the Haugh unit was 90.578, while the storage periods of 7 and 14 days were 90.322 and 90.348, respectively. In the control group without storage, the yellow index value which was determined as 53.66 % was lower than the7 (49.89 %) and 14 (47.92 %) days of storage time and the difference between the applications was significant (P <0.001). The storage time (P <0.001) and the effect of age (P <0.001) on the percentage of white were significant. Interaction between storage time and age was also found to be significant (P <0.001). The percentage of white was 55.06 %, 55.63 % and 55.51 %, respectively, control and during storage periods of 7 and 14 days. The percentage of yellow was not affected by the storage time but changed according to age. The yellow index value decreased due to the increased storage time. Shell weight per unit surface area (mg/cm2) varied with storage time and animal age (P <0.001). Animal age was effective on the number of pores (P <0.000), whereas the effect of storage time was insignificant.
