Özet |
The aim of the study was to determine the effect layer age and different plumage colors on external and internal egg quality characteristics of Japanese quails (Coturnix coturnix japonica). A total of 1,241 quail eggs at quail age of 12, 15, 18 and 21 weeks were used in the study. The eggs were gathered from quails with plumages in gray (common quail plumage), brown, white and golden. Layer age affected external quality characteristics like egg weight, shell weight and shell thickness significant (P < 0.05, P < 0.001). The differences among the plumage color groups have been significant for egg weight, shape index, shell weight and ratio (P < 0.001). Layer age affected yolk weight, albumen weight, yolk index, albumen index and Haugh unit significantly (P < 0.01, P < 0.001). In the same way significant differences have been observed between plumage color groups for yolk weight, albumen weight, yolk ratio, albumen ratio, yolk/albumen ratio, yolk index, albumen index and Haugh unit (P < 0.001). Generally, interaction between layer age and plumage color was significant (P < 0.01, P < 0.001). According to the results obtained in this research, as the quail age increased, egg weight, shell weight, yolk weight and albumen weight increased, while yolk index, albumen index and Haugh unit decreased. The Haugh units observed in quails with plumage brown, white, golden and gray were found to be higher compared to other research in literature. © Verlag Eugen Ulmer, Stuttgart. |
