A Study on the Method of Repairing Cracked SPF Eggs
Ninety small crack eggs with normal egg shape were selected and divided into three groups.Each group had three replicates,with 10 eggs in each replicate,namely the control group,solid paraffin group,and adhesive tape group.The results showed that there was no significant difference in fertilization rate among the solid paraffin group,transparent glue group,and normal group(P>0.05),but the fertilization rates of the three groups were significantly higher than those of the control group(P<0.05);In terms of embryo death rate,the order from high to low was the control group>solid paraffin group>transparent glue group>normal group.The difference between the transparent glue group and the normal group was not significant(P>0.05),but significantly lower than that between the solid paraffin group and the control group(P<0.05);In terms of hatching rate,the order from high to low was normal group>transparent glue group>solid paraffin group>control group,with significant differences among the four groups(P<0.05);In terms of hatching rate,except for the control group,there was no significant difference(P>0.05)between the solid paraffin group,the transparent glue group,and the normal group.Through the comparison of multiple indicators,it is believed that using tape to repair cracked SPF eggs is a good treatment method and has good economic benefits.
