摘要
试验选用体质健康的 34日龄断乳仔猪 ,随机分成两组 , 组 (试验组 ) 10头 , (对照组 ) 6头 ;设一重复。 组在基础日粮中添加益生素 0 .4 % , 组饲喂基础日粮 ;研究益生素对断乳日龄仔猪生产性能的影响。结果表明 : 组仔猪 6 2日龄时的平均体重为 18.82 kg,腹泻的发生率为10 .0 % ; 组仔猪 6 2日龄时的平均体重为 19.33kg,腹泻的发生率为 16 .7%。 组试猪与 组试猪相比 ,体重差异不显著 (P>0 .0 5 ) ,日增重及料肉比亦相近 。
Two lots of piglets early weaned were divided into two group at random; the first group (group Ⅰ) was fed on basal diet supplemented with EM with level of 0 4%; the second group (group Ⅱ) was fed on basal diet. The results showed that at the end of the experiment, the average weight is 18 82 kg and the incidence of diarrhea is 10% in group Ⅰ; and the average weight is 19.35 kg, the incidence of diarrhea is 16.7%.
