为了研究益生菌制剂替代抗生素对生长育肥猪生产性能的影响,选取45 kg左右的PIC生长猪30头,随机均分为A、B和C3组,A组饲喂无抗基础日粮,B、C组分别在基础日粮中添加抗生素和益生菌制剂.试验分为45～70 kg(31 d)和70～90 kg(24 d)2个阶段.结果表明:在45～70 kg阶段,B、C组猪的平均日增重和平均日采食量分别比A组高出6.17％ (P＞0.05)、1.23％ (P＞0.05)和11.94％(P＞0.05)、12.94％(P＞0.05);在70～90 kg阶段,B、C组猪的平均日增重和平均日采食量分别比A组高出16.46％(P＞0.05)、22.78％(P＜0.05)和16.38％(P＜0.05)、15.13％(P＜0.05),平均料肉比比A组分别降低了5.96％(P＞0.05)和10.03％(P＞0....

The effect of probiotic on growth performance in growing-finishing pig was conducted with 30 PIC pigs （45 kg）, which were randomly divided into three groups （A, B and C）, supplemented with basal diet, basal diet ＋ antibiotic and basal diet ＋ probiotic, respectively. The trial divided into two parts （45-70 kg, 31 d; 70N90 kg, 24 d）. The results showed that in stage one, the ADG and ADFI in group B and C were greater than that in group A by 6.17%（P〉0.05）, 1.23%（P〉0.05） and 11.94%（P〉 0.05）, 12.94%（P〉0.05） respectively. In stage...
