摘　　要：樱桃谷超级肉鸭SM2 是新型肉鸭品种 ,它在我国集约化肉鸭生产中起着举足轻重的作用 ,为了保证其生产性能的充分发挥 ,并且降低生产成本 ,探索樱桃谷超级肉鸭SM2 型肉用性能充分发挥的能量和蛋白质水平 ,以便为该肉鸭日粮的科学配制提供依据。结果表明 ,从体增重、屠宰性能两方面综合考虑 ,樱桃谷超级肉鸭日粮代谢能 0～ 2 1日龄为 12 .5 6kJ/kg、2 2～ 35日龄为 12 .14kJ/kg、36～ 4 9日龄为 12 .14kJ/kg时利用效率最高 ,日粮利用效率最高的相应粗蛋白质水平为 0～ 2 1日龄为 2 0 .5 % ,2 2～ 35日龄为 18.5 % ,36～ 4 9日龄为 16 .5 %。Cherry valley meat duck SM 2 is a new breed playing a decisive role in the intensive meat duck production of our country. In order to ensure its performance well and reduce the cost,the experiment of comparing effects of varied protein and energy levels of ration on the meat performance of the duck was carried out. The results showed that the feed efficiency was the highest when the ME and CP was 12.56 kJ/kg and 20.5% at the age of 0～21 days, the ME and CP was 12.14 kJ/kg and 18.5% at the age of 22～35 days,and 12.14 kJ/kg and 16.5% at the age of 36～49 days.
