摘　　要：为研究日粮能量、蛋白质水平对北京油鸡种公鸡后期繁殖性能的影响,将99只50周龄北京油鸡种公鸡随机分为9个处理,每个处理11只鸡,分别饲喂由能量(11.30、11.72和12.14 MJ/kg)和蛋白质(12%、14%和16%(质量分数))以3×3因子组合的9种日粮(设为处理1~9)。试验结果显示,蛋白质水平对种公鸡的生长性能和繁殖性能无显著影响(P>0.05),但精子活力随蛋白质水平的升高有降低的趋势;能量为12.14 MJ/kg时对采食量和精子活率有显著性影响(P<0.05);处理9的畸形率显著高于其他组(P<0.05)。孵化验证试验显示,处理8的受精率、孵化率和健雏率较佳。本试验结果建议北京油鸡种公鸡后期日粮蛋白质水平为12%,代谢能水平为11.72 MJ/kg,其他体重和习性类似北京油鸡的地方品种可以参照使用。This experiment was conducted to study the effects of dietary metabolized energy （ME） and crude protein （CP） levels on reproduction performance of Beijing-You chickens during the late reproductive period. Ninety-nine 50- week-old Beijing-You breeder cocks were randomly assigned to 9 treatments with11 cocks in each treatment . Three levels of dietary ME （11.30,11.72,12.14 MJ/kg ） and CP （12% ,14% ,16%） were assigned to the 9 treatments by 3 × 3 factorial experimental design. The results showed that the growth and reproductive performance were not significantly affected by CP level （ P^0.05）, but sperm motility tended to be improved with lower dietary CP level. The feed intake and sperm motility rate in 12.14 MJ/kg ME level were significantly higher than that of the other groups （ P〈 0.05）. The deformity rate of treatment 9 was significantly higher than the others. This result was verified by the incubation tests. Fertilization rate, hatching rate and healthy chick rate of the treatment 8 with 12.14 MJ/kg ME and 14% CP was the most optimized. 12% CP and 11.72 MJ/kg ME level were suggested for the diet of late reproductive period of Beijing-You chicken. Other local varieties which have similar characteristics can refer to.
