摘　　要：试验选用临产前1个月的母猪及其仔猪为研究对象,研究在日粮中添加复方中药对母猪免疫和仔猪腹泻的影响。将12只临产母猪随机分为4组,每组3只,分别为对照组和3个给药组(低、中、高剂量给药组)。对照组仅饲喂日粮,低、中、高剂量组在饲喂日粮中分别添加0.3、0.6和0.9g/kg复方中药。分别在给药后第0、10、20和30天采集血液,用于测定IgG含量、CD3^(+)含量和CD4^(+)/CD8^(+)值;在试验期内计算仔猪腹泻率和腹泻指数。结果表明,给药后第20、30天时,所有给药组IgG含量和CD3^(+)含量均显著高于对照组(P<0.05);中剂量组在用药后各测定日龄CD4^(+)/CD8^(+)值均显著高于对照组(P<0.05);中剂量组和高剂量组仔猪腹泻率分别为9.78%和11.4%,均显著低于对照组(14.76%,P<0.05);各给药组仔猪腹泻指数显著低于对照组(0.41,P<0.05),且各组之间均具有统计学差异(P<0.05)。这说明,在日粮中添加复方中药可以有效提高母猪免疫,降低和减轻仔猪腹泻的发生。The purpose of this study was to investigate the effects of compound traditional Chinese medicine(CCM)on the immune function of sows one month before parturition and diarrhea of piglets during 14 days after birth.Twelve sows were randomly divided into 4 groups,each group of three,which were control group and 3 medicine experimental groups.The control group was fed basic ration only.The boars of 3 administered groups were given CCM respectively with 0.3 g/kg,0.6 g/kg and 0.9 g/kg at low,middle,high dosage.On 0,10,20 and 30 day after administration,fasting blood was collected from the ear venous to test the contents of IgG and CD3^(+),CD4^(+)/CD8^(+)value.The diarrhea rate and diarrhea index of piglets were calculated during the experiment period.The results indicated that the contents of IgG and CD3^(+)in all treatment groups were significantly higher than those in control group(P<0.05)on the 20 th and 30 th day after administration.The CD4^(+)/CD8^(+)values in the middle dose group were significantly higher than those in the control group at all days,P<0.05.Diarrhea rates of piglets in medium-dose group and high-dose group were 9.78%and 11.4%,respectively,significantly lower than those in control group(14.76%,P<0.05).The diarrhea index of piglets among all treatment groups was significantly lower than that in the control group(0.41,P<0.05),and there were statistical differences among all groups(P<0.05).In conclusion,CCM added into the basic diet can improve immune function of sows,decrease the incidence of piglet diarrhea and reduce the diarrhea degree of piglet.
