摘要
本试验探讨饲料中添加糖萜素对早期断奶仔猪生产性能的影响.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,随机分为五组,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组在每公斤基础日粮中分别加入250 mg、500 mg糖萜素,第Ⅳ、Ⅴ组在公斤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: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组与对照组相比差异显著(P<0.05).与添加250 mg/kg糖萜素、黄霉素单独使用相比,糖萜素与黄霉素联合使用明显提高了饲料转化率,糖萜素与黄霉素表现一定的协同作用.
A study was conducted to evaluate the effects of on performance , one hundred twenty twenty- one -days piglets early weaning diarrhea（PEWD） 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 conrained 250 mg/kg Saccharicterpenin, the group treatment Ⅲ contained 500 mg/kg Saccharicterpenin, the group treatment Ⅳ 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 Saeeharieterpenin and Flavomycin were combined than alone.
