摘要: 试验选择24头“大长”仔猪,随机分为2组,即Ⅰ和Ⅱ组,进行3个阶段105 d的饲养对比试验。在试验基础日粮中,Ⅰ组添加1.5%的试验复合预混料A,Ⅱ组添加1.5%的市售复合预混料B作为对照,观察其增重效果和肌肉品质。试验结果表明,试验期Ⅰ、Ⅱ组肉猪的日增重分别为856和867 g,差异不显著(P>0.05);平均料重比分别为3.19和3.15 ,差异不显著(P>0.05);但肉质分析,Ⅰ组试猪中肌肉颜色、pH、大理石纹、嫩度、系水力和肌肉脂肪都分别优于对照组10.00%、3.68%、16.67%、9.38%、6.71%和13.07%,差异显著(P<0.05);增重1 kg耗预混料成本分别为0.79元和0.72元,Ⅰ组比Ⅱ组高了9.7%,1头猪多耗费饲料成本5.60元,但该产品具有较大的应用前景。

Abstract: Divided into two groups in random(groups ⅠandⅡ),twenty-four piglets were fed the dietary with 1.5% premix feed from different sources for 105 days in three stages. The results showed that the average daily gain of groupⅠandⅡ was 856 and 867 grams respectively and average ratio of feed to gain was 3.19 and 3.15 respectively.There was no significant differences (P>0.05) between them. However,the group Ⅰhad better performance: meat color, pH, marbling, muscle tenderness, water nolding capatity and intramuscular fat was better than group Ⅱ by 10.00%, 3.68%, 16.67%, 9.38%, 6.71% and 13.07%, which was obviously different from group Ⅱ(P<0.05). Though the average premix cost for one kilo-gram gain was 0.79 and 0.72 yuan respectively. The cost of groupⅠwas rised by 9.70% comparing with group Ⅱ, a pig need much feed cost than groupⅡby 5.6yuan,but this product would have extensive use in furure.
