修补破损种蛋提高种蛋利用率试验

破损种蛋一般认为不能用于孵化,而被废弃。笔者对三种较为简单易行的修补破损种蛋的方法进行了试验,证明了破损种蛋通过修补可与正常种蛋一样用于常规孵化。将破损种蛋按不同破损程度和形状、不同修补时间、不同修补材料、破损蛋与完好蛋、破损蛋修补与不修补分成五组进行对比试验,每组重复三次。经修补的破损种蛋,孵化率为80.15%,与正常种蛋孵化率(87.14%)差异不显著(P>0.05)。修补的破损种蛋孵化率显著高于未修补的破损种蛋孵化率,分别为81.24%和33.91%。用胶水、浆糊、透明胶带修补的破损种蛋孵化率分别为81.01%、80.16%、68.98%。将破损种蛋分成第二天修补、第四天修补、第六天修补三类,同时入孵,结果为第二天、第四天、第六天修补的孵化率分别为81.06%、76.28%、62.54%。由此可见,破损种蛋在内壳膜没有破裂的情况下,完全可以用来孵化。

Test on Raising Hatching Egg Utilization through Mending Broken Egg

Broken hatching eggs were abandoned because those eggs can not used to hatch. In this paper, an experiment of mending hatching eggs was conducted, the results indicated that the broken eggs can hatch after mending. Broken eggs were di- vided into five groups according to damage degree and form, mending time, mending materials, broken and nomal eggs, men- ding eggs and eggs without mending, three replicates in each group. No significant difference （P〉0. 05） was observed between mending eggs hatching rate （ 80.15%） and nomal eggs hatching rate （87.14%）. Hatching rate of mending eggs （81.21%） was significantly higher than eggs without mending （33.91%）. Hatching rates of eggs were 81.01 %, 80.16 % and 68.98%, s respectively, mending with glue, paste and transparent adhesive tape. Hatching rates of eggs were 81.06%, 76.28% and 62. 54%, respectively, for mending the second day, the fourth day and the sixth day. Therefore, broken eggs can hatch through mending under the condition of no rupture for the inner shell membrane.
