| 摘 要： | 将72头30日龄长大二元断奶仔猪按照体重相近、性别比基本相同的原则随机分为试验组和对照组,对照组采用常规饲料饲喂,试验组在常规饲料中添加0.25%的微生态制剂,均匀拌料后供猪自由采食。结果显示：试验组较对照组平均日增重提高33.3%（P〈0.05）,料肉比降低了25.1%,发病率降低36.1%（P〈0.01）,仔猪血清中免疫球蛋白IgA浓度在0.05水平上无差异;在试验期,试验组可比对照组多收入815.09元,每头猪可比对照组猪多收入22.64元。表明该微生态制剂有促进断奶仔猪生长、增强免疫力的作用,且能较大幅度提高经济效益。

| Abstract: | 72 weaned piglets at 30 days old were separated randomly into testing group and control group,which had basically the same weight and sex ratio.Piglets in control group were fed with usual feedstuff.Feedstuff in testing group was supplemented with 0.25 % micro-ecological agent.Result showed that the average daily gain weight,food-meet rate and disease incidence rate of testing group increased by 33.3 %(P<0.05),25.1 % and 36.1 %(P<0.01),respectively,compared with those of control group.IgA concentration showed no significant difference(P>0.05).Economic income of testing group was 815.09 RMB more than that of control group.And the income of each piglet in testing group was 22.64 RMB more.Therefore,micro-ecological agent could promote weaned piglet growth,immunize against diseases and increase economic benefit by a large margin. |
