The effects of incubation temperature on the sex of Japanese quail chicks were investigated in this study. The study was conducted on Japanese quail. In all, 4500 eggs obtained from 2 generations were used. At the beginning of the study, a new flock was formed from available hatching eggs. Hatching eggs were gathered at 3 different ages (8 to 10 weeks, 16 to 18 weeks and 22 to 24 weeks of age) from the laying period in this flock. These eggs were exposed to 5 different incubation temperatures (36.7, 37.2, 37.7, 38.2, and 38.7°C). The hatching results were evaluated for each group. Chicks obtained from these temperature groups were reared separately to obtain quail for breeding. Eggs for incubation were gathered from these breeding quail when they were between 15 and 18 weeks of age. These eggs were placed in an incubator at a standard (37.7°C) temperature, separated by F(1)-generation temperature groups. The chicks in all groups were reared separately, and the sex of the chicks was determined at maturity. Statistical differences (P < 0.05) were found for the sex of the chicks in the third group (22 to 24 weeks) of the F(1) generation, compared with other groups. This result confirmed the hypothesis that different incubation temperatures for the first generation (at the embryo stage) might influence the sex of the next generation of chicks. Further studies are needed to investigate the effects of incubation temperature on chicks from different perspectives.
本研究探讨了孵化温度对日本鹌鹑雏鸡性别的影响。研究对象为日本鹌鹑。总共使用了来自 2 个世代的 4500 个鸡蛋。在研究开始时，从可孵化的鸡蛋中形成了一个新的群体。在这个群体的产卵期，从 3 个不同的年龄（8 到 10 周、16 到 18 周和 22 到 24 周）收集孵化鸡蛋。这些鸡蛋暴露在 5 种不同的孵化温度（36.7、37.2、37.7、38.2 和 38.7°C）下。对每个组的孵化结果进行了评估。从这些温度组获得的小鸡分别饲养，以获得用于繁殖的鹌鹑。当这些繁殖鹌鹑年龄在 15 到 18 周之间时，从它们那里收集用于孵化的鸡蛋。这些鸡蛋被放置在标准（37.7°C）温度的孵化器中，按 F(1)-代温度组进行分离。所有组的小鸡都分别饲养，在成熟时确定小鸡的性别。在 F(1)代的第三组（22 到 24 周）中，小鸡的性别与其他组相比存在统计学差异（P < 0.05）。这一结果证实了这样一个假设，即第一代（胚胎阶段）的不同孵化温度可能会影响下一代小鸡的性别。需要进一步研究从不同角度研究孵化温度对小鸡的影响。
