不同品种鹅种蛋品质的比较分析

为了研究不同品种鹅在相同饲养管理条件下其种蛋品质的异同。随机选取浙东白鹅（65周龄）、四川白鹅（76周龄）、豁眼鹅（66周龄）的种蛋各50枚，分别测定其物理特性和化学特性指标。结果表明：三品种间蛋的比重、蛋黄重、蛋壳比例、粗蛋白、粗灰分及蛋壳中钙磷含量差异不显著(P>0.05)。浙东白鹅的蛋重、蛋壳强度、蛋壳厚度、蛋白高度、哈夫单位、蛋黄颜色、蛋白重、蛋白比例、蛋壳重指标均高于四川白鹅与豁眼鹅（P<0.05或P<0.01）；豁眼鹅的蛋形指数、蛋壳颜色、蛋黄比例、粗脂肪含量均高于浙东白鹅与四川白鹅（P<0.05或P<0.01）；四川白鹅的多数指标介于浙东白鹅与豁眼鹅之间。不同品种鹅蛋品质差异为蛋品质的选择改良提供了很好的素材，并为人们日常生活中合理消费鹅蛋提供理论依据。

Comparison Analysis of Geese Egg Quality Between Different Geese Breeds

This study was conducted to compare the quality of eggs reproduced by different breeds geese at the same feeding and management.50 geese eggs each breeds of Zhedong White Geese（65 weeks of age）,Sichuan White Geese（76 weeks of age）,Huoyan Geese（66 weeks of age） were randomly selected to determine their indicators of physical and chemical properties so as to compare their difference of eggs quality.The results showed that there were no significant differences（P0.05） between three breeds in egg specific density,yolk weight,eggshells proportion,crude protein,crude ash and eggshells ＇ calcium and phosphorus.The Zhedong White Geese ＇ s egg weight,eggshell strength,eggshell thickness,albumen height,haugh unit,yolk color,protein weight,protein proportion,eggshell weight,index were higher than the Sichuan White Geese ＇ s and Huoyan Geese ＇ s（P0.05 or P0.01）;Huoyan Geese ＇ s egg shape index,eggshell color,yolk proportion,and crude fat content were higher than Zhedong White Geese and Sichuan White Geese（P0.05 or P0.01）;Many indexes of Sichuan White Geese were between Zhedong White Geese and Huoyan Geese.Different varieties of egg quality difference for egg quality improvement provided very good material,and for the people in daily life and provided theoretical basis for rational consumption of eggs.
