不同营养水平对肉兔生产性能的影响

Effect of Different Nutrient Levels on Growth Performances in the New Zealand White Rabbits

采用U6 (63 ×3)均匀设计方案,选择35日龄断奶新西兰白兔144只,进行为期6 周的饲养试验,主要探讨了消化能、粗蛋白、粗纤维等3 个因素及3 个水平对肉兔增重、饲料消耗、料肉比等指标的影响。结果表明,最优组合为消化能9.62MJ/kg、粗蛋白13.5% 、粗纤维17% ,能量是肉兔采食和生长的限制性因素。

The effects of three factors (DE,CP,CF) were determined with the method of uniform probability design.The growth performances of New Zealand White rabbits were also monitored.The results showed that the optimistic level is DE 9.62MJ/kg,CP 13.5%,CF 17%.Energy is the limit factor for intake and growth of the animal.
