摘要： 通过人工感染预防试验和治疗试验,对由常山、青蒿、柴胡、苦参、苦楝根、黄芪等13种中草药按不同组成和配比组成的5个不同中药复方的抗球虫效果进行了试验观察。结果在5个中药复方中,预防试验复方4(0.5 mL/d)的抗球虫指数最高(ACI=110.07),是阳性对照组的193.0%,存活率为100%,卵囊值较低,为20;治疗试验复方4高剂量组(1.0 mL/d)的存活率相对较高,为95%;预防试验复方1和复方3存活率较高,均为93.33%,在预防试验和治疗试验复方1和复方3的卵囊值均为20,相对于其他中药复方和阳性对照组较低。结果表明,常山配比高的复方可明显降低鸡球虫感染后的卵囊值,青蒿配比高的复方可明显提高鸡球虫感染后的存活率。

Abstract: Coccidiostat effect of f ive Chinese herbal medicine prescriptions was studied through prophylactic trials and therapeut ic tests using chickens artificially infected with Eimeria tenella. The five prescriptions were made of different compatible proportions of herbs out of 13 Chinese medicinal herbs (Changshan, Qinghao, Chaihu, Kushen, Kuliangen,Huangqi and etc. ). The result was: in prophylactic trials, the anticoccidial index (ACI) of prescription 4 group(0.5 mL/ d) was 110. 07, the highest among the five prescriptions, and was 193% that of the posit ive control group.The survival rate of this group was 100%, and the oocyst index was 20 (comparatively low); The survival rate in prescription4 high dose group (1.0 mL/ d) was 95% (comparatively high); Survival rates of prescription 1 and 3 group inprophylactic trials were both 93.33% (comparatively high), and oocyst index of both groups in prophylact ic trials andtherapeutic tests were 20, which was lower than other prescription groups and positive control group. The results indicatedthat prescriptions with higher compatible proportion of Changshan could reduce the oocyst index significantly, and with higher compatible proportion of Qinghao could remarkably improve the survival rates of chicken artificially infected with Eimeria tenella.
