本研究以贵妃鸡（G）和麒麟鸡（K）为素材，比较贵妃鸡♂×麒麟鸡♀（GK）、麒麟鸡♂×贵妃鸡♀（KG）两种组合公鸡的体重、饲料报酬以及生长速率。结果表明：①体重：GK、KG组合的出壳重分别为34.76g和28.99g，差异极显著（P<0.01）。16周龄GK、KG组合体重分别为1464.81g和1433.62g，差异显著（P<0.05）；②饲料报酬：16周龄GK、KG组合公鸡的料重比分别为5.36和4.33。总体来讲，1~9周龄KG组合公鸡饲料转化率不如GK组合，而10~16周龄KG组合公鸡饲料转化率优于GK组合；③生长速率：GK组合公鸡的生长速率均高于KG组合，1周龄内的相对生长速率最大。随着日龄的增加，相对生长速率均呈现逐渐下降的趋势。

In this experiment, Princess chicken(G) and Frizzle Chicken(K) were crossed, and the body weight, feed reward and growth rate of two combinations (G♂×K♀,K♂×G♀)of male were compared. The results showed that: ①body weight :The average weight of GK (34.76g) and KG (28.99g) at age of one day had a very significant difference (P<0.01).The average weight of GK of the male was 1464.81g ,of GK of the male was 1433.62g, which were in a significant difference level (P<0.05).②feed reward: the feed conversion 16 weeks of the male of GK and KG respectively, were 5.36and 4.33. In general, in the experiment the GK accumulative feed conversion were higher than the KG in 1 to 9 weeks, but lower in 10 to 16 weeks.③growth rate: The GK growth rate was higher than the KG. The chicken in first week relative growth rate was reach maximum. With the age increasing, the relative growth rate showed a decreasing trend.
