| Abstract | |
Aim: In this study was aimed to determining internal and
external quality of quail eggs with different eggshell colour,
spot colour and spottiness. Material and Methods: In this study, daily collected 318 eggs were used. The treatment groups were classified as those with very large brown spots on greyish white eggshell colour (I), black spots of varying size on greyish white eggshell colour (II), large brown spots on brown eggshell colour (III), widely distributed brown spots on brown eggshell colour (IV), and blue spots of varying size on greyish white eggshell colour (V). The eggs were individually numbered. External quality characteristics were identified before egg broken out. After eggs were broken out, long and short diameter of albumen, albumen height, yolk diameter and yolk height were evaluated. Results: The differences for value of eggshell percentage and shell index between groups were statistically significant (P<0.01). The differences for albumen index, yolk index and Haugh unit between groups were significant (P<0.01, P<0. 001). Conclusion: It may be expressed that eggshell colour and spot colour in quail eggs are significantly affected egg quailty characteristics like eggshell percentage, shell eggs index, albumen index, yolk index and haugh unit. |
