种蛋摆放方式和通风时间对孵化率影响的研究

种蛋的孵化率收到诸多因素的影响,正确的摆放方式和合适的通风时间,对提高孵化率有着积极意义。通过对种蛋摆放方式、通风时间等孵化条件的改变进行对比试验。结果表明,保存过程中,如果使种蛋小头朝上,大头朝下,并提早通风,可使受精蛋孵化率和入孵蛋孵化率明显提高,差异极显著(P<0.01)。

The Influence of Ways of Deposition and Ventilated Time of Breeding Eggs on Hatchability

Many factors take effect on the hatchability rate of eggs,it's important to improve the hatching rate by applying the correct way of laying up eggs and suitable ventilation time.The comparative tests on the way of laying up eggs and ventilation time was made in the study.The result indicated that the fertilization to hatching eggs and hatching rate markedly improved by the project that the small head upwards,the big head downwards,and shift to an earlier time for ventilated time during the process of preser...
