The effeciancy of some anticoccidial drugs were tested for the treatment fo E. tenella infection in chickens. Four drugs were used. The first was composed of Sulphaquinoxalin and Trimethoprim; the Second of Sulpaquinoxalin Diaveridine; the third of Sulphaquinoxalin and Amprolium,  and the fourth of Amprolium and Furaltadon. Criteria used in the evaluation of drugs performance were, weight gain; feed consumption and conversion; total oocyst counts, and packed cell volume. The highest percent of protection (102%) was obtained with the first drug. The second, third and fourth drugs gave 99.8, 64.4, and 45.7 percents of protection, respectively.
