鹅蛋与鸭蛋生物学特性的比较

Biological Characteristics Comparison of Eggs between Goose and Duck

作者旨在研究地方品种鹅蛋与鸭蛋的生物学特性差异。同期采集固始白鹅种蛋56枚,淮南麻鸭种蛋64枚,对外部特征和内部品质进行对比。结果表明二者之间存在较大差异,鹅蛋与鸭蛋各指标分别为:蛋重(159.1 g,62.17 g)、蛋比重(1.119,1.094)、蛋壳厚度(0.514 mm,0.311 mm)、哈氏单位(107.77,86.14)、蛋黄比例(38.12%,30.28%)、蛋壳比例(12.32%,11.19%),以上指标鹅蛋均高于鸭蛋。鸭蛋蛋黄色泽优于鹅蛋,罗氏比色鸭蛋、鹅蛋分别为11.33和4.52。鸭蛋的血肉斑率达到12.5%,明显高于鹅蛋的3.57%,需要通过育种手段来降低。

In order to discover the differences of eggs between goose ang duck, 56 eggs of Gushi White Goose and 64 eggs of Huainan Ma Duck were involved in this study. The results shown that, every outside and inside characteristics of goose eggs and duck eggs were： egg weight （159.1 g, 62.17g）, egg specific density （1. 119, 1. 094）, egg shell thickness （ 0. 514 mm, 0.311 mm）, Haugh unit （107. 77, 86. 14）, proportion of yolk （38. 12%, 30. 28%）, proportion of egg shell （12. 32%, 11.19%）, respectively. Egg yolk color of duck is deeper compare with goose, roche color were 11.30 and 4, 52 respectively. The rate of blood and meat-spot of duck eggs was 12.5%, compare with 3.57% of goose eggs.
