摘　　要：该文收集某种鸡场祖代肉种鸡养殖一线相关生产数据,总结分析了祖代肉种鸡B系与D系生产性能和繁殖性能差异性。结果显示:在产蛋性能方面,B系种母鸡开产时间比D系晚3周,B系种母鸡开产时体重比D系重820 g。B系种母鸡28~58周平均产蛋率46.0%,只均产蛋数104个,而D系种母鸡25~66周平均产蛋率70.4%,只均产蛋数207个;在死淘率方面,B系种母鸡产蛋期死淘率比D系种母鸡高0.65个百分点;在繁殖性能方面,B系种母鸡种蛋合格率比D系种母鸡低5.27%, B系种母鸡只受精蛋数为87个,明显少于D系种母鸡的185个,B系种母鸡受精率比D系种母鸡约低1.7个百分点,健雏率接近,B系种母鸡提供的雏鸡数为80只,明显低于D系种母鸡的172只。可见,B系种母鸡综合繁殖能力约为D系的一半。This article collects relevant production data on the front line of ancestral broiler breeding in a certain chicken farm,summarizes and analyzes the differences in production and reproductive performance between the B and D broiler breeding. Theresults showed that in terms of laying performance, B-line broiler breeding hens started laying 3 weeks later than D-line, and B-linebroiler breeding hens weighed 820 g heavier than D-line when they started laying.The average egg laying rate of B-line broilerbreeding hens from 28 to 58 weeks was 46.0%, with an average egg laying of 104 per hen, while the average egg laying rate ofD-line broiler breeding hens from 25 to 66 weeks was 70.4%, with an average egg laying of 207 per hen. In terms of mortality rate, the mortality rate of B-line broiler breeding hens during egg laying was 0.65 percentage points greater than that of D-line broilerhens;In terms of reproductive performance, the qualified egg rate of B-line broiler breeding hens was 5.27% lower than that ofD-line. The number of fertilized eggs in B-line broiler breeding hens was 87, significantly less than 185 eggs laid by D-line. Thefertilization rate of B-line broiler breeding hens was about 1.7 percentage points lighter than that of D-line, and the healthy chickrate of different hens was similar. The number of chicks provided by B-line broiler breeding hens was 80, significantly lower than172 chicks provided by D-line. Conclusion: The comprehensive reproductive ability of B-line broiler breeding hens was about halfof that of D-line broiler breeding hens.
