    摘要:

    对已严重杂交退化的吉林地方鸡——芦花鸡,采用家系选育方法,提纯复壮,选育了3个世代。结果表明,育雏期成活率98.9%,72周死淘率8.7%。芦花鸡的开产日龄稳定在158~168 d,开产母鸡体重由0世代1 973.37±313.0 g到第三世代1818.83±275.6 g,降低了154.53 g(7.63%);300日龄产蛋量由零世代的95.08±9.72到第三世代的103.56±11.57,提高了8.48枚,平均每世代提高2.83枚;500日龄产蛋量由215.29±8.7枚提高到231.97±13.1枚,提高了16.68枚,平均每世代5.56枚;300 d蛋重由0世代的56.69±4.31 g到第三世代的55.81±6.13 g,降低了0.79 g,平均每世代降低0.26 g;受精率各世代稳定在89.68%~91.50%之间,受精蛋孵化率,从零世代的80.21%提高到三世代的85.63%。群体整齐度由0世代的56.7%提高到89.1%。外貌特征渐趋一致。表现了良好的适应性和抗病性。

    Abstract:

    By method of pedigree breeding and purification and rejuvenation,severely degenerated native Luhua chicken breed was bred for 3 generation.The results showed that the survival rate in brooding period was 98.9%,mortality and elimination rate in 72weeks was 8.7%.Open production day was in 158-168 d,and laying chicken gain reduced 7.63%,i.e.,from 1973.37 ± 313.0 g in 0 generation to 1818.83 ± 275.6 g in 3rd generation.Egg production in 300 day increased for 8.48,i.e.,from 95.08 ± 9.72 in 0 generation to 103.56 ± 11.57 in 3rd generation,Average 2.83 increase for each generation.Egg production in 500 day increased 16.68,i.e.,from 215.29 to 231.9.Average 5.56 increase for each generation.Egg weight in 300 day lowed for 0.79 g,i.e.,from 59.69 ± 4.31 in 0 generation to 58.90 ± 6.13 g in 3rd generation.Average 0.26 g decrease for each generation.Fertilization rate in every generation was between 89.68% and 91.50%.Hatching rate of fertilization egg in 0 generation was 80.21%,while in 3rd generation was 85.6%.Uniformity in groups was 56.7% in 0 generation and 89.1% in 3rd generation.Appearance characteristics were consistency.Luhua chicken breed had good adaptability and resistance to disease.
