Özet
Bu çalışma, bıldırcın (Coturnix coturnix japonica) kuluçkalık yumurtalarının uzun süreli depolama ve yüksek kuluçka sıcaklığı uygulamalarının civciv kalitesi üzerine etkisini Tona skorlama yöntemini kullanarak belirlemek amacıyla planlanmıştır. Çalışmada elde edilen veriler tesadüf bloklarında faktöriyel deneme planı uygulanarak analiz edilmiş ve çoklu ortalamaların karşılaştırılmasında Dunnet testi kullanılmıştır. Deneme grupları ilk 7 gün yüksek sıcaklığa (38.6°C) maruz bırakılan A grubu, depolama uygulanan ve 37.6 °C sıcaklık uygulanan B grubu, 14 gün depolama ve ilk 7 gün yüksek sıcaklık (38.6°C) uygulanan C grubu ile depolanmayan ve 37.6 °C sıcaklık uygulanan kontrol grubu (K) şeklinde oluşturulmuştur. Transfer ağırlık kaybı oranı (%) gruplara göre önemli farklılık göstermiştir(P<0.01). Depolama sonrası (14 gün) gelişim döneminin ilk 7 günü boyunca yüksek kuluçka sıcaklığına maruz kalan B grubundaki transfer ağırlık kaybı %12.04 ile K grubundan (%10.80) daha yüksek olmuştur. Uygulama gruplarının 392-400 ve 424-432. saatler arasındaki civciv çıkış aralıkları üzerine etkisiz ancak, 376-384 (P<0.05), 384-392 (P< 0.01), 400-408 (P< 0.01), 408-416 (P<0.05) ve 416-424 (P< 0.05) saatleri arasındaki çıkış aralığı üzerine etkisi önemli belirlenmiştir. En yoğun civciv çıkışları 376-384. saatleri arasında A grubunda, 384-392. saatler arasında K grubunda, 400-408. saatleri arasında B grubunda, 408-416 ve 416-424. saatleri arasında C grubunda olmuştur. Satılabilir nitelikteki civciv çıkış ağırlığı üzerine grup etkisi, blok etkisi ve grup*blok interaksiyonu (etkileşim) önemli bulunmuştur (P<0.01). Civciv boyu bakımından grup (P<0.01), blok (P<0.01) ve grup*blok interaksiyonu (P<0.05) önemli bulunmuştur. Uygulamaların Tona skoru üzerine etkisi önemli (P<0.01) olmuş, Tona skoru ortalaması en yüksek 98.10 değeri ile K grubunda belirlenmiş, bunu sırası ile B, A ve C grupları izlemiştir. Sarısız vücut ağırlığı üzerine uygulama X blok interaksiyonu etkisi ve uygulama grup etkisi önemsiz bulunmuştur. Çıkış gücü üzerine uygulamaların etkisi önemlidir (P<0.01). Birinci ve ikinci dönem embriyo ölümü üzerine uygulamalar (P<0.01; P<0.05) etkili ancak, üçüncü dönem embriyo ölümleri üzerine etkisiz olmuştur.
This study was planned to determine the effect of long-term storage and high hatching temperature applications of quail (Coturnix coturnix japonica) hatching eggs on chick quality using the Tona scoring method. The data obtained in the study were analyzed by applying a factorial experiment plan in random blocks and Dunnet test was used to compare multiple means. Experimental groups are group A exposed to high temperature (38.6°C) for the first week, group B exposed to storage (14 days) and 37.6°C temperature, group C applied to storage (14 days) and to high temperature (38.6°C) for the first 7 days, and K group applied to temperature (37.6 °C) without storage. The rate of transfer weight loss (%) differed significantly according to the groups (P<0.01). Transfer weight loss in group B exposed to high incubation temperature during the first 7 days of the development period after storage (14 days) was 12.04% higher than that of group K (10.80%). The effect of treatment groups on chick hatching intervals was not significant between hours of 392-400 ve 424-432 but it was significant hours of 376-384 (P<0.05), 384-392 (P< 0.01), 400-408 (P< 0.01), 408-416 (P<0.05) ve 416-424 (P< 0.05) statistically. The busiest chick hatches are 376-384. Between the hours of 384-392 in group A. in the K group between hours, 400-408. Between the hours of 408-416 and 416-424 in group B. was in group C between hours. Group effect, block effect and group*block interaction (interaction) were found to be significant on sellable chick hatching weight (P<0.01). Group (P<0.01), block (P<0.01) and group*block interaction (P<0.012) were found to be significant in terms of chick size. The effect of the applications on the Tona score was significant (P<0.001). The average Tona score was determined with the highest value of 98.10 in the K group, followed by the B, A and C groups, respectively. The effect of application X block interaction and application group effect on body weight without yolk were found to be insignificant. The effect of applications on output power is significant (P<0.001). Treatments were effective on first and second embryo death (P<0.001; P<0.05), but were ineffective on third term embryo death.
