中文摘要：

为了研究发酵饲料能否替代抗生素在断奶仔猪生产性能上的作用,选用90头28日龄断奶杜长大仔猪,随机分为3组,每组3个重复,每个重复10头。试验分为对照组Ⅰ（不含抗生素）、对照组Ⅱ（含抗生素）、试验组（发酵全价料,且不含抗生素）。试验结果表明：试验组日增重比对照组Ⅰ和Ⅱ分别增重24.1%（P〈0.01）、12.5%（P〈0.01）,差异极显著;料肉比分别比对照组Ⅰ和Ⅱ降低4.9（P〈0.05）、2.8（P〉0.05）,试验组和对照组Ⅰ差异显著,但和对照组Ⅱ差异不显著;腹泻率分别比对照组I和Ⅱ降低77.8%（P〈0.05）和63.6%（P〉0.05）。由此可见：发酵全价料能明显提高断奶仔猪的生产性能,提高饲料的利用率,降低腹泻率;发酵饲料可取代抗生素在饲料中的添加。

英文摘要：

In order to study the effect of fermentation instead of antibiotics on weaned piglets＂ growth performance, 90 weaned piglets of 28-day-old are selected to be randomly divided into 3 groups, Every group sets up 3 repetitions, and 10 piglets in each repetition. For experiment, there are contrast group I （without antibiotics）, contrast group II （with antibiotics）, test group（full-price fermentation and no antibiotics）. Test results show that the daily gain of the test group is 24.1%（P〈0.01） and 12.5%（P〈0.01） more over contrast group I and II, an extremely significant difference; feed/gain rate decreases by 4.9% （P〈0.05） and 2.8% （P〉0.05） over contrast I and II, there is a large difference between test group and contrast group I , but a small difference between test group and contrast II. Diarrhea rates compared with the control groupI and II decreased 77.8% and 63.6%,and the experimental group and control group I significantly different（P〈0.05）,and the control group II was not significantly. Therefore, full-price fermentation can obviously improve the production performance of weaned piglets, the utilization of feed, as well reduce diarrhoea rate; fermentation can substitute for antibiotics as additive in feed.
