摘要
对安义瓦灰鸡进行了快羽和慢羽纯系的选育研究,其快羽、慢羽纯系配套后代的自别雌雄准确率达94.96%以上。探讨了羽速基因对安义瓦灰鸡产蛋性能、蛋品质、早期生长速度、体尺性状和屠宰性能的影响,结果显示:5～6周龄慢羽鸡的平均体重显著大于快羽鸡;快羽公鸡的头重极显著地大于慢羽公鸡,慢羽母鸡的半净膛重和脚重均显著地大于快羽母鸡;快羽纯系的62周龄产蛋量极显著地低于慢羽纯系;其他性能在快羽、慢羽纯系之间的差异均不显著。
The breeding of rapidly - feathering pure line and slowly - feathering pure line of Anyi tile - like gray chicken was carried out. The autosexing accurate rate of the progenies from the hybrid combinations of the two pure lines reached 94.96%. The influences of feathering speed gene on the egg production performance, egg quality, growth speed at early stage, traits of body size and slaughter properties of Anyi tile - like gray chicken were explored. The results showed that the average body weight of 5 - 6 - week - old slowly - feathering chickens was significantly larger than that of rapidly - feathering chickens at the same age. The head weight of rapidly - feathering cocks was extremely significantly higher than that of slowly - feathering cocks. The semi - eviscerated weight and foot weight of slowly - feathering hens were significantly larger than those of rapidly - feathering hens. The egg production of 62 - week - old rapidly - feathering pure line was very significantly lower than that of slowly - feathering pure line at the same age. The differences in other performances between the rapidly - feathering pure line and the slowly - feathering pure line were not significant.
