The aim of the successful incubation period is to achieve maximum health chicks in each batch. Therefore, all factors affecting incubation have to be investigated in detail. This study investigated the effect of eggshell thickness on hatchability of quail eggs.
A total of 1415 eggs were collected from the same flock at the ages of 23 and 41 weeks. Two different incubations were performed at these eggs. Eggshell thicknesses of all eggs were determined with an ultrasonic gauge before incubation. Incubation period was applied as for 18 days. After 15 days of incubation, eggs were transferred to hatching machine. Eggs were classified as thin-, medium-, and thick-shelled according to eggshell thickness values.
Eggshell thicknesses were ranged between 0.24 and 0.36 mm, and the differences between the hatching rates of thickness values were not found significant. Hatchability of thin-, medium-, and thick-shelled eggs was found as 69.2%, 69.4%, and 82.4% for Experiment 1. These values were as 87.8%, 89.2%, and 91.9% for Experiment 2, respectively. Similar to eggshell thickness frequencies, the differences between hatching rates of eggshell thickness groups were found insignificant.
Results of this study showed that eggshell thickness does not affect hatchability.
成功孵化期的目标是在每一批次中获得最大数量的健康雏鸡。因此，必须详细研究影响孵化的所有因素。本研究调查了蛋壳厚度对鹌鹑蛋孵化率的影响。
从同一鸡群中收集了1415枚23周龄和41周龄的蛋。对这些蛋进行了两种不同的孵化。在孵化前，用超声波测量仪测定所有蛋的蛋壳厚度。孵化期设定为18天。孵化15天后，将蛋转移到孵化机中。根据蛋壳厚度值，将蛋分为薄壳、中壳和厚壳三类。
蛋壳厚度在0.24至0.36毫米之间，厚度值的孵化率差异不显著。实验1中，薄壳、中壳和厚壳蛋的孵化率分别为69.2%、69.4%和82.4%。实验2中，这些值分别为87.8%、89.2%和91.9%。与蛋壳厚度频率相似，蛋壳厚度组的孵化率差异不显著。
本研究结果表明，蛋壳厚度不影响孵化率。
