摘要
试验选择600只青脚麻种母鸡,按24-28周龄、29-35周龄、36-42周龄及43周龄以上4个不同产蛋周龄和春夏秋冬4个不同季节分别收集种蛋进行孵化,研究不同季节和不同产蛋周龄对种蛋受精率和孵化率的影响。结果发现,不同产蛋周龄对青脚麻鸡种蛋的孵化性能有一定的影响,处于产蛋期29-35周龄的种鸡所产种蛋孵化性能最好;不同季节对青脚麻鸡种蛋的孵化性能也有一定的影响,秋季的孵化性能最好。
The eggs of 600 Cyan-shank partridge chicken at the age of 24-28 weeks, 29-35 weeks, 36-42 weeks or 43 weeks were selected for studying the influence of the age and seasons on the fertility and hatchability. The results showed that the different egg-laying age had certain effects to the hatching performance of the Cyan-shank partridge chicken and the hatch performance of eggs from 29-35 weeks old chicken was the best. The seasons also could influence the hatch performance of the eggs and the hatch performance was the best in autumn.
