摘要
为了探讨贵妃鸡的合理饲养标准,获得更大的经济效益,选270只42日龄健康、体重无明显差异的生长期贵妃鸡,随机分成9组,采用3种能量水平,3种粗蛋白水平日粮,进行饲养试验和代谢试验。结果表明,能量为11.70 MJ/kg,粗蛋白为17%的日粮,对贵妃鸡日增重、日采食量、饲料转化率影响效果最好,且经济效益最大。
270 42 d healthy royal chickens were divided into 9 groups randomly. Royal chickens were fed on the ration formulation with three kinds of energy level and three kinds of protein level respectively. We carried on the feeding experiment and metabolism test. The result showed that the group with metabolizable energy for 11. 70 MJ/kg and crude protein for 17% was the best feeding result of daily gain, daily intake, feed conversion rate and economic effect.
