Prediction of albumen weight, yolk weight, and shell weight as egg weight in japanese quail eggs

Bu araştırma, bıldırcın yumurtalarında ak ağırlığı, sarı ağırlığı ve kabuk ağırlığının belirlenmesinde yumurta ağırlığının bir tahminci olarak kullanılabilme imkanının tespiti ve yumurta ağırlığı ile ak, sarı ve kabuk ağırlıkları arasındaki ilişkiyi açıklamak için en uygun modellerin tespiti amacıyla yapılmıştır. Ard arda üç gün süreyle toplanmış, toplam 175 bıldırcın yumurtası bu araştırmada kullanılmıştır. Yumurtalar 20 haftalık yaştaki 72 bıldırcından elde edilmiştir. Araştırmada yumurta ağırlığı ile ak (0.94), sarı (0.77) ve kabuk (0.61) ağırlıkları arasında tespit edilen fenotipik korelasyonlar istatistiki olarak önemli bulunmuştur (P

Japon bıldırcını yumurtalarında yumurta ağırlığı kullanılarak ak ağırlığı, sarı ağırlığı ve kabuk ağırlığının tahmin edilmesi

This study was conducted to determine the most adequate models for defining the correlation between the egg weight and the albumen, yolk and shell weights as well as pointing out the practicability options for determining the egg weight as an estimator of the egg shell, egg yolk and the egg albumen weights in the quail eggs. In this experiment, a total of 175 eggs were collected in 3 consecutive days from 72 female quails, aged 20 weeks. The birds were housed as 1 male/3 female per cage of 40x30x30 cm at Quail Research unit of the Department of Zo-otechnia, Faculty of Veterinary Medicine, and Firat University. The highest phenotypic correlation was determined between egg weight and albumen weight (0.94). The least phenotypic correlation was determined between egg weight and shell weight (0.61). Coefficients of determinations (R2) indicated that quadratic, logistic and exponential models showed the better fit to explain the relationship between the egg weight and the albumen weight respectively. On the other hand, the best models used in defining of the correlation between the egg weight and the yolk weight are quadratic, linear, logistic, and exponential models. As for the relationship between the egg weight and the shell weight; quadratic, linear, logistic, and exponential models were mostly accurate. As a result of the research, it was determined that it was possible to use the egg weight as the estimator of the albumen and the yolk weights by using a suitable model, however, it was not fully possible for the determination of the shell weight.
