| 摘 要： | 应用综合指数选择法对白番鸭父系、母系进行继代选育.结果表明:第3世代父系10周龄公母鸭体重比母系公母鸭分别重280.18g(P<0.05)和242.91g(P<0.05).父系经2世代选择,公母鸭26周龄体重比0世代分别增加330和80g;而母系经2世代选择,公母鸭26周龄体重增加不显著(P>0.05).父系经2世代选择,其母鸭56周龄蛋重比0世代重3.41g,每只母鸭平均产蛋量增加3.86枚.母系经2世代选择,其56周龄产蛋量比0世代增加8枚,蛋重增加0.45g.可见应用综合指数选择法连续2世代选育能明显提高白番鸭的生产性能.

Application of synthetic index selection in muscovy duck breeding |
| |
| Abstract: | The method of synthetic index selection was applied to continuous progeny breeding for paternal and maternal lines of parental generation in white muscovy duck. The results showed that: (1) the average body weights of male and female ducks (at the age of 10 weeks) of paternal line were 280.18 and 242.91 g heavier than those of maternal line respectively (P<0.05) in the third generation; (2) the average body weights of male and female ducks (at the age of 26 weeks) were 300 and 80 g heavier in the third generation of paternal line than those in the first generation, and there was no singnificant difference (P>0.05) of the average body weight between the third and the first generation of maternal line; (3) the average weight of eggs of paternal line at the age of 56 weeks in the third generation was 3.14 g heavier than that in first generation, but the number of eggs of each duck in the third generation was only 3.86 more than that in the first generation; (4) the number of eggs of each duck of maternal line in the third generation at the age of 56 weeks was 8 more than that in the first generation, but the averge weight of eggs was only 0.45 g heavier than that in the first generation. The conclusion was that the productive ability of white muscovy duck was increased throught three generation selection. |
