摘 要:[目的]探讨不同蛋重对青脚麻鸡种蛋孵化效果的影响。[方法]选择300枚青脚麻鸡种蛋,按重量大小分为3组:Ⅰ组蛋重为48. 62~55.99 g,Ⅱ组蛋重为56.00~59.92 g,Ⅲ组蛋重为59.93~69.99 g。入孵后第6、12和18天分别从各组取10枚发育正常的种蛋,分离出蛋壳、蛋白、蛋黄和胚胎,计算各组种蛋重量的变化,并对其孵化效果进行分析。[结果]Ⅱ组受精蛋孵化率和入孵蛋孵化率最高,分别为95.59%和93.00%,Ⅱ组入孵蛋孵化率分别比Ⅰ组、Ⅲ组高12.05%和14.81%(P<0.05),出雏率为93.00%。雏鸡初生重随蛋重的增加而显著增大。[结论]蛋重56.00~59.92 g的青脚麻鸡种蛋的孵化效果较好。[Objective]To study the influences of different egg weight on the hatching effect of green foot chicken eggs.[Method]300 breed eggs of Qinjiaoma chicken were selected and divided into 3 groups according to the egg weight.The egg weight in groupⅠ,Ⅱ,Ⅲwere 48.62-55.99,56.00-59.92 and 59.93-69.99 g,respectively.10 healthy breed eggs were taken from each group on the 6 th,12 th and 18 th day after hatching,the eggshell,protein,yolk and embryo were separated,and the weight variation of breed eggs in each group were calculated,and the hatching effect was analyzed.[Result]The hatching rate of fertilized eggs and hatching rate of incubation eggs in groupⅡwere the highest,being 95.59%and 93.00%respectively.The hatching rate of incubation eggs in groupⅡincreased by 12.05%and 14.81%respectively.The hatching rate in groupⅡwas 93.00%.The birth weight of chicks significantly increased with the increase of egg weight.[Conclusion]The hatching effect of breed eggs of Qinjiaoma chicken with the weight of 56.00-59.92 g was better.
