雷州黑鴨青殼與白殼蛋蛋品質比較分析
[Abstract]:In order to compare and analyze the egg quality of Leizhou black duck with different shell colors, 30 green and 30 white shell commercial eggs produced by Leizhou black duck aged 21 weeks were selected. The egg shape index, eggshell color, eggshell strength, eggshell thickness, egg weight, yolk weight, egg shape index, egg shell color, egg shell strength, egg shell thickness, egg weight and yolk weight were measured. Yolk color, Hough unit, and analysis. Results: the average values of egg shell thickness, egg shell strength, egg weight, egg yolk weight, protein height and Hafu unit were higher than those of white shell egg, while the mean value of yolk colorimetric and relative weight of egg yolk was lower than that of white shell egg (P0.05). The egg shell thickness, egg shell strength, egg yolk weight and egg weight, egg yolk relative weight and egg yolk weight, Hafu unit and protein height of green shell and white shell were positively correlated with each other (P0.01). The relative weight of eggshell yolk was negatively correlated with eggshell color, protein height and eggshell thickness (P0.05). The relative weight of white shell egg yolk was negatively correlated with egg shell thickness (P0.05). Egg yolk colorimetric index, egg shape index, protein height and egg weight were positively correlated with egg yolk weight (P0.05). The results showed that the main differences between Leizhou black duck green shell egg and white shell egg were egg shell color, egg weight, egg shape index, egg shell thickness and egg shell strength, which were important indexes for breeding Leizhou black duck eggs.
