魔芋粉饲喂肉鸭的价值探讨

Research of konjac residue in diet on production performance of the growing meat ducks

试验用含魔芋粉0%、2%、3%、4%的饲粮饲喂12日龄的樱桃谷杂交肉鸭SM3,探讨魔芋粉作为一种饲料原料的饲用价值。结果表明:用含魔芋粉的日粮饲喂肉鸭,对肉鸭的日增重、耗料量和增重饲料成本没有明显影响(P>0.05),但对鸭的总增重和经济效益有一定影响。在本试验中,添加2%的魔芋粉使肉鸭的总增重增加,经济效益最好。

To inquires into the possibility of feeding ducks with konjac residue,SM3 meat ducks of 12 clays old are feeded with diet containing 0%,2%,3%,4%konjac residue.The results indicated that there was no difference in the daily weight gain,the feed intake and the cost of feed for 1 kg of weight gain with the diet containing konjac residue.However,there was significant difference on the total weight gain and benefit.Under the experimental condition,the optimum rate of konjac residue was 2%,supplementing 2% konjac residue can increase the total increment of ducks and make the profit reach the maximum.
