Japon bıldırcınların yumurta kalite özellikleri arasındaki ilişkinin incelenmesi

Abstract

The aim of this study was to determine relationships between eggs characteristics of Japanese quails with different colors (white, dark brown, yellow and original). The egg weight, shape index, specific gravity, albumen index, yolk index, yolk weight, albumen weight, shell thickness, shell weight, albumen height and Haugh unit of 247 eggs, obtained from four different color and four week fattening period of quail, were determined. Using the coefficients of variation homogeneity of the data of egg characteristics were checked. Correlation matrix was used to determine the relationship between the characteristics of the egg. The lowest variation of specific gravity values were in white, dark brown and yellow color of quails, respectively, 0.57%, 0.38% and 0.47%, and yolk index values with 3.54% in the original color of the quail. The highest variation of albumen height values were 17.67%, 17.04%, 17.70% and 14.97% for white, dark brown, yellow and original color in the quails, respectively. The data of egg feature appears to be homogeneous. The highest correlation coefficients occurred between albumen height-Haugh unit (0.988) and egg weight-current weight (0.735) in the white quail; unit (0.982) and egg weight-current weight (0.831) in the yellow color quail, and the albumen height-haugh unit (0.993) and egg weight-current weight (0.630) in the original color quail. Overall, correlation coefficient between albumen height and haugh unit higher than the other quality characteristics was concluded
