蛋鸡种蛋蛋重对孵化率和雏鸡生长发育的影响

The Effects of Egg Weights of Breeding Layers on Hatchability and Development of Chicks

摘要:将豫州褐壳蛋的种蛋按重量大小分成6组,在相同的条件下进行孵化和饲养试验。结果表明:蛋重在53～56克的种蛋,其受精蛋孵化率最高;不同的蛋重对雏鸡的初生重以及雏鸡在1～3周龄的体重影响较大:蛋重与初生重(γ=0.9899)、1周龄体重(γ=0.9528)的相关极显著;蛋重与2周龄体重(γ=0.9032)、3周龄体重(γ=0.9040)相关显著,与3周龄以后雏鸡体重相关不显著。

Breeding eggs from Yuzhou brown eggshell layers wer e divided into six groups according to weights,then conducted the experiments o f hatching and raising in the same environment.Results indicated as follows : Breeding eggs whose weights were from53g to56g had the highest hatchability ;egg weights greatly affected birth weights and body weights of1～3week-old chicks:egg weight had significant correlation with birth weight (?=0.9 899)and one-week-old body weigh(?=0.9528)as well as two-week-o ld(?=0.9032)and three-week-old body weight (?=0.9040),but did not with body weight after third week.
