【摘要】 选用健康的 36头“大×长×杜”仔猪 ,随机分为三组 ,不同来源的猪用预混料按 4 %的比例分别添加到各试验基础日粮中 ,试验期为 2 5天。结果表明三组仔猪的日增重依次为Ⅰ组 6 4 3G、Ⅱ组为 6 5 5G、Ⅲ组为 6 0 4G ,Ⅰ、Ⅱ组之间差异不显著 (P >0 0 5 ) ,Ⅰ、Ⅱ组与Ⅲ组间的差异显著 (P <0 0 1) ;三组仔猪的平均料重比分别为 198、196、2 14,增重 1KG分别消耗预混料成本 0 .6 1元、0 .5 2元和 0 5 1元 ,三组饲喂养效果以Ⅱ组仔猪的生长速度最快 ,Ⅲ组预混料成本最低 ,Ⅱ组的料重比低于Ⅲ组 ,日增重高于Ⅲ。更多还原

【Abstract】 Divided into three groups inrandom(Ⅰ,Ⅱ,Ⅲ),thirty\|six piglets were fed the dietary with 4% premix feed from different source for 30 days in three stages. The results shows that the average daily gain of group Ⅰ,Ⅱ,Ⅲ was 643g,655g and 604g respectively. there was no significant differences (>0.05) between Ⅰ and Ⅱ. But there was a remarkable difference (<0.01) between Ⅱ and Ⅲ. Average ratio of feed to gain was 1.98,1.96 and 2.14 resperctively. Group Ⅱ was best. The average premix cost for one kilograme gain was 0.61 yuan,0.52 yuan and 0.51 yuan respectively. there was a remarkable different among the groups. there was no significant difference between Ⅱ and Ⅲ,but the average ratio of feed to gain of group Ⅲ was higher than the group Ⅱ.更多还原
