摘要
用 690头杜长大三元杂交仔猪进行试验 试验结果表明 :满足仔猪日增重最高时日粮中的添加量为铜 2 50mg/kg ,锌 (氧化锌 ) 2 613mg/kg ,铁 2 15mg/kg ;满足耗料比最低时的添加量为铜 2 50mg/kg ,锌 (氧化锌 ) 2 655mg/kg ,铁 172mg/kg ;满足腹泻率最低时的添加量为铜 2 50mg/kg ,锌 (氧化锌 ) 2 717mg/kg ,铁
The results showed that the optimum allowance of Cu Zn and Fe for the requirement of the highest lightest daily gain was 250mg/kg ,2613mg/kg,and 215mg/kg respectively. For the highest feed conversion rate,the optimum allowance of Cu,Zn and Fe the lowest diarrhoea rate,the optimum allowance of Cu,Zn and Fe was,250mg/kg,2717mg/kg and 153mg/kg,respectively.
