ABSTRACT
Twenty Baladi lambs aged 3-4 months were found naturally infected with coccidia. Six species of Eimeria were identified, which are E. ninakohlyakimovae, E. parva, E. intricata, E. granulosa, E. cr and allis, and E. ovina. Trials for treatment of such infestation were made using one old traditional anticoccidial drug [Amprolium] and two recent preparations, which are AS supermed [combination of Amprolium and sulphaquinoxaline], Baycox [Toltrazuril]. The criteria used for the efficacy of such drugs are oocyst discharge and body gain. It was found after the statistical analysis that, Amprolium is still the drug of choice in treatment of coccidiosis in lambs. On the other h and, the efficacy of Baycox and AS supermed is quite equal in decreasing oocyst discharge and increasing body weight of treated lambs
