中文摘要:
      为比较地方鸡种和高产蛋鸡蛋品质之间的差异,以黑羽绿壳蛋鸡和白来航鸡为对象,测定比较其从 开产至72 周龄时的蛋品质。结果表明:两个鸡种各周龄的蛋重、蛋白高度、蛋壳颜色(L、a、b)、蛋壳强度、蛋黄 比率、蛋黄蛋白比在整个产蛋周期中均存在极显著差异;哈氏单位除了72 周龄时差异不显著外,其他周龄时两个 鸡种间的差异均达到极显著水平;蛋形指数在开产和32 周龄时差异极显著;蛋黄颜色在32、40、56 周龄时两个 鸡种间的差异均达到显著性水平;蛋壳厚度在开产、48、60 周龄时的差异显著;蛋壳比率除了40、52、72 周龄时 两个鸡种间的差异不显著外,其他周龄时均达到显著性水平。绿壳蛋鸡和白来航鸡从开产至72 周龄的蛋重分别 可以用38、39 周龄来代替,哈氏单位分别可以用48、50 周龄代替,蛋黄蛋白比分别可以用36、32 周龄代替。
英文摘要:
      In order to study the differences in egg quality between high-yielding layer and native layer,egg quality from the age at first egg to 72-week-old of green-eggshell layer black feather pure lines and White Leghorn were measured and compared in different weeks. The results showed that,egg weight,albumen height,eggshell color( L, a,b),eggshell strength,yolk rate and rate of yolk and albumen in each week between green-eggshell layer and White Leghorn had extremely significant differences,the same as Haugh unit except at 72-week-old. The egg index at the age of first egg and 32-week-old had extremely significant difference,yolk color at the age of 32,40 and 56-week-old, eggshell thickness at the age of first egg,48 and 60-week-old,eggshell rate in each week beside 40,52 and 72 weekold, all of them had significant differences in the two breeds. Egg weight,Haugh unit and rate of albumn weight and yolk weight of green-eggshell layer and White Leghorn in the period from the age of first egg to 72-week-old could be replaced by 38-week-old and 39-week-old,48-week-old and 50-week-old,36-week-old and 32-week-old, respectively
