【摘要】：为比较分析不同壳色雷州黑鸭蛋蛋品质,试验选取21周龄雷州黑鸭所产的青壳和白壳商品蛋各30个,测定蛋形指数、蛋壳颜色、蛋壳强度、蛋壳厚度、蛋重、蛋黄重、蛋黄颜色、哈夫单位,并进行分析。结果:青壳蛋蛋壳厚度、蛋壳强度、蛋重、蛋黄重、蛋白高度、哈夫单位的均值均高于白壳蛋,而蛋黄比色和蛋黄相对重的均值低于白壳蛋(P0.05);青壳和白壳蛋的蛋壳厚度和蛋壳强度、蛋黄重和蛋重、蛋黄相对重和蛋黄重、哈夫单位和蛋白高度均呈极显著正相关(P0.01);而青壳蛋蛋黄相对重和蛋壳颜色、蛋白高度和蛋壳厚度呈显著负相关(P0.05);白壳蛋黄相对重和蛋壳厚度显著负相关(P0.05),蛋黄比色和蛋形指数、蛋白高度和蛋重、蛋白高度和蛋黄重显著正相关(P0.05)。结果表明:雷州黑鸭青壳蛋与白壳蛋的主要区别在于蛋壳颜色,蛋重、蛋形指数、蛋壳厚度、蛋壳强度是雷州黑鸭蛋用性能选育的重要指标。
[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.
