以湖北省农业科学院试验种猪场的54头“大长”仔猪为试验动物，随机分为3个组，即Ⅰ、Ⅱ和Ⅲ组，进行3个阶段105 d的饲养对比试验。在试验基础日粮中按4%分别添加不同来源的猪用预混合饲料饲喂试验动物，观察其增重效果和肉品质。试验结果，试验全期Ⅰ、Ⅱ和Ⅲ组的平均日增重依次分别为759，750和746 g，差异不显著(P>0.01)；平均料肉比依次分别为3.19，3.15和3.19，差异不显著(P>0.01)；胴体质量和肉品质很一致；但增重1 kg耗预混合料成本依次分别为0.64,0.75和0.74元，Ⅰ组比Ⅱ组和Ⅲ组分别降低17.2%和15.6%，差异极显著(P<0.01)。结果表明，3个组饲喂效果一致，且都达到较好水平，但以成本计，则显示Ⅰ组预混料为优。

Divided into three groups in random(i,e groups Ⅰ,Ⅱ and Ⅲ), fifty-four piglets were fed the dietary with 4% premix feed from different sources for 105 days in three stages. The results showed that the average daily gain of group Ⅰ, Ⅱ and Ⅲ was 759, 750 and 746 grammes respectively and average ratio of feed to gain was 3.19, 3.15 and 3.19 respectively. There was no significant differences(P＞0.01) between them. However the average premix cost for one kilogram gain was 0.64, 0.75 and 0.74 yuan respectively. The cost of group Ⅰ was reduced by 17.2% and 15.6% comparing with group Ⅱ and Ⅲ. There was a remarkable difference between them. Therefore the results indicated that the premix for group Ⅰ was better than others.
