| 摘 要： | 通过不同贮存时间对海兰褐祖代鸡孵化率影响的研究,为规模化种鸡场孵化管理提供参考.试验将来源相同的种蛋分别贮存2、3、4、5、6、7、8、9、10,1、1 d,其他贮存条件相同.同机同批孵化,分析其受精蛋孵化率.实验结果表明:贮存9 d以内的种蛋,各贮存日龄间受精蛋孵化率差异不显著(P>0.05);贮存2 d与10 d;8 d、9 d与11 d间受精蛋孵化率差异显著(P<0.05);贮存2~7 d分别与贮存10 d,贮存3~4 d分别与贮存11 d之间的受精蛋孵化率差异均达到极显著(P<0.01),保存期超过9 d后,受精蛋孵化率明显降低(P<0.01).

| Abstract: | This experiment studied on the different effects on Hailan hatching rates for a condition to exactly the same temperature,relative humidity ventilated etc.,but storage time was different.Results show that interactions of less than 9 d preserved eggs for hatch rates of fertilized eggs has no significant（P0.05）.There is significant（P0.05） difference of the hatch rates between 2 d preserved eggs and 10 d preserved eggs,and between 8 d,9 d preserved eggs and 11 d preserved eggs.There is extremely significant（P0.01） difference of the hatch rates between 2~7 d preserved eggs and 11 d preserved eggs,and between 8~4 d preserved eggs and 10d preserved eggs. |
