摘要
选用21日龄左右健康无病、初重基本一致的杜长大猪进行饲喂试验,随机分为5组,每组3个重复,每重复8头猪,自由采食和自由饮水。试验设计为:第Ⅰ组为对照组,第Ⅱ、Ⅲ组在每千克基础日粮中分别加入2505、00 mg糖萜素,第Ⅳ、Ⅴ组在每千克基础日粮中分别加入250 mg糖萜素+4 mg黄霉素、4 mg黄霉素。结果表明:①第Ⅱ、Ⅲ、Ⅳ、Ⅴ组的平均末重较对照组分别提高4.00%、12.30%、5.21%、2.64%,平均日增重第Ⅲ组显著高于对照组(P<0.05)。与第Ⅱ、Ⅴ组相比,第Ⅳ组可提高饲料转化率,表明糖萜素与黄霉素具有一定的协同作用。②盲肠中大肠杆菌,各试验组均有一定的抑制作用,尤其是第Ⅳ组效果最好;结肠、直肠中大肠杆菌,试验组Ⅱ、Ⅲ、Ⅳ显著低于对照组Ⅰ和Ⅴ(P<0.05),其中Ⅲ组大肠杆菌含量最低(P>0.05)。处理Ⅲ能显著增加盲肠中双歧杆菌数(P<0.05),处理Ⅳ能显著增加盲肠中乳酸杆菌数(P<0.05),各处理组与对照组相比,均能增加结肠和直肠中双歧杆菌数和乳酸杆菌数,但差异不显著(P>0.05)。
A study was conducted to evaluate the effects of on performance and Intestinal Bacilli ,one hundred twenty twenty-one-days of Early Weaned Piglets were randomly assigned to five treatments with three replicates, there were eight piglets perreplicate. Feed and water were provided ad limbitum. All of piglets were fed with a common corn soybean meal based diet. Treatments were as follows：the control group（no Saccharicterpenin and no Flavomycin）,the group treatment Ⅱ contained 250 mg/kg Saccharicterpenin,the group treatment Ⅲ contained 500 mg/kg Saccharicterpenin, the group treatmentIV contained 250 mg/kg Saccharicterpenin plus 4 mg/kg Flavomycin , the group treatment Ⅴ contained 4 mg/kg Flavomycin. The results showed that：Supplemented with Saccharicterpenin the ADG and ADFI of piglets were higher,compared to control group, the average final wt of treatment Ⅱ , Ⅲ , Ⅳ, Ⅴ was higher 4.00 %, 12.30 %, 5.21%, 2.64 %;the ADG of group treatment was significantly improved（P〈0.05）. FCR was highter when 250 mg/kg Saccharicterpenin and Flavomycin were combined than alone.
