[ Method] The fresh feces were collected from two chicken farms, and Eimeria coccidia strains were isolated and propagated in laboratory. A total of eight anticoccidial drugs including diclazuril, robenidine, dinitoimide, decoquinate, nicarbazine, maduramicin, salinomycin and lasalocid were selected for sensitivity test. [ Results] In Farm I, Eimeria coccidia strains were sensitive to decoquinate, partially resistant to nicarbazine and completely resistant to other six drugs. In Farm II, Eimeria coccidia strains were sensitive to decoquinate and nicarbazine, partially resistant to robenidine and completely resistant to other five drugs. [ Conclusion] Drug resistance of Eimerfa coccidia to many anticoccidial drugs had been highly developed in these two farms.展开更多
