探讨中药对自然感染猪圆环病毒2型（PCV2）仔猪生长性能和猪瘟疫苗免疫应答的影响，结果显示：1％中药组、1.5％中药组、2.0％中药组的日增重分别比对照组提高30.40％（ P＜0.05）、28.88％（ P＜0.05）和31.06％（ P＜0.05），饲料转化率分别比对照组提高2.02％、7.25％和10.26％，日采食量分别比对照组提高26.23％、14.75％和9.84％，猪瘟抗体阻断率分别比对照组提高9.57％、18.27％和30.93％（ P＜0.05），猪瘟抗体阳性率均大于70％，1.5％中药组、2.0％中药组的猪瘟抗体变异系数均小于40％。表明自拟中药方剂可较好地控制PCV2，提高仔猪生长性能和增强猪瘟疫苗免疫应答，且以2％中药组效果最好。

A traditional Chinese medicine (TCM ) was formulated to study its effect on the growth and immune-response to the hog cholera vaccine of the piglets .The results showed that ,as compared with Control ,the daily weight gains of the piglets in Group A ,B and C increased by 30.40% (P<0.05) ,28.88% (P<0.05) and 31.06%(P<0.05) ,respectively ;the feed conversion ratios increased by 2.02% ,7.25% and 10.26% ,respectively ;the daily feed intakes increased by 26.23% ,14.75% and 9.84% ,respectively ;and ,the rates of blocking the classic swine fever antibody increased by 9.57% ,18.27% and 30.93% (P< 0.05) ,respectively .The rates of positive classic swine fever antibody in all three treatment groups were greater than 70% ,and the variation coefficients of Group B and C were lower than 40% .It appeared that the TCM used had a measurable effect on PCV2 infection , piglet growth ,as well as the piglet's immune-response to the hog cholera vaccine .Insofar as TCM dosage is concerned ,the best result was obtained on Group C that had a 2% addition on its feed .
