摘要
[目的]研究微生物发酵饲料对仔猪生长性能的影响,为其推广和应用提供依据。[方法]选用60头体重约8～10 kg的杜×长×大三元杂交断奶仔猪,随机分为6栏,10头/栏。对照组饲喂无抗浓缩料和金霉素70 mg/kg,试验组为微生物发酵饲料添加组,饲喂无抗浓缩料和微生物发酵料。[结果]饲用微生物发酵饲料组比常规饲料组平均日增重提高了5.56%,而料重比降低了3.53%。此外,试验组粪便中有益菌群增多,pH值下降,与对照组结果差异显著(P<0.05)。[结论]微生物发酵饲料可代替抗生素添加饲料,并可起到促进仔猪健康生长的功效。
[Objective] To study the effects of microbial fermentation feeds on growth performance of piglets,and provide the basis for their promotion and application.[Methods] All of 60 Duroc×Landrace×Yorkshire crossbred weaned piglets,weighing 8-10 kg,were randomly housed in six groups,10 piglets in each group.The piglets in control groups were fed with traditional daily food which contained aureomycin at 70 mg/kg·bw and concentrate feeds without antibiotics.While the piglets in experimental groups were fed with concentrate feeds without antibiotics and microbial fermentation feeds.[Result] The results indicated that the average daily gain of experimental groups raised by 5.56%,and the feed conversion ratio reduced by 3.53% compared to control group（P0.05）.Moreover,the number of probiotics in the feces of experimental groups increased and pH decreased significantly compared with the control groups.[Conclusion] Microbial fermentation feeds can be used to replace antibiotics feeds,and promote healthy growth of the piglets.
