摘要
不同年龄阶段的武定鸡分别采食能量蛋白均不同的 4组日粮 ,试验结果表明 :0~ 6周龄 ,7~ 12周龄和 13周龄以上武定鸡分别饲喂代谢能为 12 97MJ/kg ,12 5 5MJ/kg ,12 97MJ/kg ,蛋白 (CP)为 2 1% ,19% ,17%的日粮可获得最高的平均日增重 ;能量、蛋白低于此水平的 ,武定鸡的日增重和饲料报酬均明显降低 。
This research was about the nutritional level of Wuding chicken of different age stages, the results showed that when the Wuding chicken of 0~6 weeks,7~12 weeks and beyond 12 weeks were fed diets with ME and CP 12 97?MJ/kg,12 55?MJ/kg,12 97?MJ/kg and 21%,19%,17% respectively the average day gain reached the highest. But if the amounts of ME and CP below these levels ,not only the day gain and feed efficiency would reduce but also the cost of feedwould increase.
