摘　　要：为研究加味郁金散对断奶仔猪生长性能及血清免疫指标的影响,本试验选取28 d体重相近的三元杂交"杜长大"断奶仔猪36头,共设4个处理组,每组3个重复,每个重复3头猪,其中Ⅰ组为对照组全期饲喂基础日粮+金霉素160 mg/kg,Ⅱ~IV组分别在基础日粮中添加0.05%、0.1%、0.2%加味郁金散,试验期为21 d,分为前期1~7 d,中期8~14 d,后期15~21 d三个阶段。试验结果显示:生长性能全期1~21 d,Ⅰ、Ⅲ组平均日增重(ADG)、平均日采食量(ADFI)、料重比(F/G)显著优于Ⅱ、Ⅳ组(P<0.05),Ⅲ组ADG、ADFI、F/G、腹泻率优于Ⅰ组但差异不显著(P>0.05),Ⅲ组比Ⅱ、Ⅳ组ADG提升11.85%、10.33%(P<0.05),ADFI提高69.53%、62.45%(P<0.05),F/G降低4.49%,3.25%(P<0.05),腹泻率降低73.30%、69.19%(P<0.05)。血清免疫指标8~14 d,加味郁金散Ⅲ组IgA、IgG显著优于抗生素组(P<0.05),IgA比Ⅱ、Ⅳ组提升10.09%、17.65%(P<0.05),IgG比Ⅳ组提升7.16%(P<0.05)。15~21 d,加味郁金散组Ⅲ组IgA、IgG、IgM显著优于抗生素组(P<0.05),IgA比Ⅱ、Ⅳ组提升13.91%、11.02%(P<0.05),IgG提升8.22%、8.85%(P<0.05),IgM比Ⅱ组提升13.15%(P<0.05)。综合结果表明,加味郁金散可以提升断奶仔猪生长性,能降低腹泻率,提高断奶仔猪血清免疫指标,其中添加量为0.1%时效果最好。The experiment was conducted to investigate the effect of Jiawei Yujin San on growth performance and serum immune indexes of weaned piglets. 36 ＂Duroc × Landrace × Yorkshire＂ crossbred weaned piglets with similar weight at the age of 28 d were seclected,which were allocated into 4 groups with 3 replicates,and 3 pigs per replicate.The control group（group Ⅰ） was fed the basal diet ＋ aureomycin 160 mg/kg,Ⅱ ～ Ⅳ groups were added to the diets of 0.05%,0.1%,0.2%Jiawei Yu Jin San.The test period of 21 d was divided into early 1 ～ 7 d,middle 8 ～ 14 d,late 15 ～ 28 d stage.The test results showed that the growth performance of the whole 1 ～ 21 d.The average daily gain（ADG）,average daily feed intake（ADFI）,feed/gain（F/G） in group Ⅰ, Ⅲ were significantly higher than that of groups Ⅱ, Ⅳ（P〈0.05）,ADG,ADFI,F/G,the diarrhea rate in group Ⅲ were better than group Ⅰ but the difference was not significant（P〈0.05）,group ⅢADG significantly better than groupⅡ,Ⅳ 11.85%,10.33%（P〈0.05）,ADFI 69.53%,62.45%（P〈0.05）,F/G 4.49%,3.25%（P〈0.05）,diarrhea rate decreased by 73.30%,69.19%（P〈0.05）.Serum immune indexes 8 ～14 d, Ⅲ group IgA and IgG were significantly better than those of the antibiotic group（P〈0.05）,IgA increased by 10.09% and 17.65%（P〈0.05）compared with group Ⅱ and Ⅳ,IgG increased 7.16% compared with Ⅳ group（P〈0.05）.15 ～ 21 d,group Ⅲ IgA,IgG,IgM were significantly better than those in the antibiotic group（P〈0.05）,which increased by 13.91% and 11.02%（P〈0.05）compared with group Ⅱ and Ⅳ,IgG increased by 8.22% and 8.85%（P〈0.05）,and IgM increased by 13.15%（P〈0.05） compared with group Ⅱ.The comprehensive results showed that the Jiawei Yujin San could enhance the growth performance and reduce the diarrhea rate of weaned piglets,improve the serum immune indexes of weaned piglets,and the best effect was when the dosage was 0.1%.
