In modern poultry husbandry, storing fertilized eggs is a common measure to cope with the variable demands of the market and the maximum hatching capacity of the hatchery. However, this measure is harmful to the hatchability of eggs and the quality of newly hatched birds. Knowledge about the effects of storing fertilized eggs on the performance of goslings is still limited. The objective of this study was to investigate the effects of storing fertilized eggs on egg quality, hatchability, gosling quality, hatching weight, post-hatching growth performance, and amino acid profile in albumen and newly hatched goslings' serum. A total of 1,080 fertilized goose eggs (Jilin White goose) with a similar egg weight (126.56 ± 0.66 g) were used in this study. All eggs were distributed into 3 groups with 24 replicates per group and 15 eggs per replicate. The differences between groups were the storage duration of eggs (0, 7, or 14 d). We found that the Haugh unit, yolk weight, and eggshell weight decreased linearly, whereas the albumen pH increased linearly, with storage duration. Prolonging storage duration had negative effects on hatchability, hatching weight, post-hatching growth performance parameters, and gosling quality in a time-dependent manner. The analysis of the amino acid profile in albumen and newly-hatched goslings' serum showed that the amino acid content increased linearly with storage duration. Additionally, eggs stored for 14 d had the worst performance for all measured parameters. Therefore, we concluded that the storage of fertilized eggs negatively affects egg quality and post-hatching gosling quality. To produce high-quality goslings, it is necessary to shorten the storage duration for fertilized eggs.
在现代家禽养殖业中，储存受精蛋是应对市场需求变化和孵化场最大孵化能力的常见措施。然而，这种措施对蛋的孵化率和新孵化鸟类的质量有害。关于储存受精蛋对鹅仔性能影响的知识仍然有限。本研究的目的是研究储存受精蛋对蛋品质、孵化率、鹅仔质量、孵化重量、孵化后生长性能以及蛋白和新孵化鹅仔血清中氨基酸谱的影响。本研究共使用了 1080 枚具有相似蛋重（126.56±0.66g）的受精鹅蛋（吉林白鹅）。所有的蛋被分配到 3 组，每组 24 个重复，每个重复 15 个蛋。组间的差异是蛋的储存时间（0、7 或 14d）。我们发现哈夫单位、蛋黄重和蛋壳重呈线性下降，而蛋白 pH 值随储存时间呈线性上升。延长储存时间会对孵化率、孵化重量、孵化后生长性能参数和鹅仔质量产生负面影响，且这种负面影响具有时间依赖性。蛋白和新孵化鹅仔血清中氨基酸谱的分析表明，氨基酸含量随储存时间呈线性增加。此外，储存 14d 的蛋在所有测量参数上的表现最差。因此，我们得出结论，储存受精蛋会对蛋品质和孵化后鹅仔质量产生负面影响。为了生产高质量的鹅仔，有必要缩短储存受精蛋的时间。
