The Increasing resistance of coccidia to anticoccidial drugs currently used by the poultry industry has stimulated the search for new method of control. As part of this effort have investigated medicinal plants as a potential source and safe alternative of compounds with anticoccidial activity. In this research efficacy of Artemisia annua against coccidiosis in broiler were compared with salinomycin and amprolium. 24 groups of sex male broiler in age 21 day classification in 6 drug class include 1 Amprolum 2- salinomycin, 3- leaves 2.5%, a-ether petroleum extract, 5efraction with maximum of artemisinin, 6-un treated. In each class we have 4 groups include: 1 infected with Eimeria tenella, 2- infected with Eimeria maxima, 3- infected with Eimeria accervolina 4_ uninfected. Lesion scores, body weight gains. Feed conversion and oocyst extraction were investigated of the 7 days after infection. The bird treated with salinomycin, extract, fraction and amprolium showed similar weightgain and significantly higher than untreated groups. All treated groups have better feed conversion efficiency than the untreated group. In infected groups addition of all drugs significantly reduced the number of oocysts per chicken of faces. In conclusion, the data of body weight gains, lesion scores, and oocyst extractions indicate that ether petroleum extract of artemisia annua or fraction with maximum of artemisinin were effective for prevention of coccidiosis but ether petrolum extract is cheep and convenient in compared with fraetion
