In this study, we investigated the effect of modification of 12 d storage conditions of quail eggs from two flocks: at 17–20 weeks of life (A) and 36–39 weeks of life (B) on the incubation time, hatch window (HW), hatching results and chicks quality. The eggs were divided into experimental groups: COI = no pre-incubation (PI); SPIDES = were treated with 4 h PI, delivered at 4, 6, 8 and 10 d of storage; EG SPIDES = were treated with variable time of PI according to the scheme 5 d – 2 h, 7 d – 3 h, 9 d – 5 h and 11 d – 6 h. In addition, in each group, half of the eggs were turned (T) every 12 h, which is indicated as COI T, SPIDES T and EG SPIDES T. Pre-incubation was conducted at 37.8°C and 50–55% RH. It has been demonstrated that both storage profiles contribute to shortened incubation time, yet the HW is deteriorated if T is not applied. The benefits resulting from the EG SPIDES profile is an increase of 2.3 points in the “average score of all chicks” index compared to the COI group. In summary, the use of PI and T, and in particular the EG SPIDES profile with the concomitant use of T during long storage of quail eggs is recommended to obtain a considerable improvement of hatching results and chick quality.

预孵化和长期保存过程中的翻车作为提高日本鹌鹑蛋孵化率和雏鸡质量的方法

在这项研究中，我们研究了两种鸡群的鹌鹑蛋12 d贮藏条件的改变对孵化时间，孵化时间（孵化时间为17-20周（A）和36-39周（B））的影响。 HW），孵化结果和雏鸡质量。将卵分为实验组：COI =无预培养（PI）；SPIDES =用4 h PI处理，分别在第4、6、8和10天储存；根据方案5 d – 2 h，7 d – 3 h，9 d – 5 h和11 d – 6 h用可变时间的PI治疗EG SPIDES =。此外，每组中每12小时将一半的卵翻（T），表示为COI T，SPIDES T和EG SPIDEST。预培养在37.8°C和50-55％RH下进行。已经证明，两种储存曲线都有助于缩短孵育时间，但是如果不施用T，则HW会变差。与COI组相比，EG SPIDES配置文件所带来的好处是“所有小鸡的平均得分”指数提高了2.3点。总之，建议在长时间保存鹌鹑蛋的同时使用PI和T，尤其是EG SPIDES曲线以及T的同时使用，以显着改善孵化结果和雏鸡质量。
