--- This study aimed to determine the score of macroscopic intestinal lesions of coccidiosis in broiler chickens challenged with strains of local field E. acervulina, E. maxima and E. tenella and supplemented with an anticoccidial program (Salinomycin / nicarbazin). The study was conducted in the experimental shed Avian Pathology Laboratory, Faculty of Veterinary Medicine of the National University of San Marcos; T1 (n = 150), T2 (n = 150), T3 (n = 150) and T4 (n = 150) with 6 replicates: 600 broilers where the Cobb Vantress line 500. The design included 4 treatments were used per treatment. T3 and T4 received different doses of Salinomycin / nicarbazin, 40 or 50 ppm of active ingredient each program respectively, and were challenged at 14 days of age, orally with 1 mL of an inoculum with oocysts collected Eimerias field. mortality, clinical signs and intestinal lesions compatible with coccidia was recorded from 14 to 28 days old. On the 7th day post challenge the score for coccidial lesions macroscopic scale using + 0 to + 4 described in 1970 by Johnson and Reid was determined. The presence of Eimeria species was confirmed by scraping the intestinal mucosa. In broilers, against a challenge with pathogenic Eimerias premises, the anticoccidial treatment demonstrated a significant reduction in mortality and clinical signs coccidiosis, and a significant reduction of the score of macroscopic intestinal lesions of Eimeria acervulina and Eimeria maxima (p <0.05), but not of Eimeria tenella. Statistical analysis was performed using Stata 12.0 (Stata Corp)program. Key words: Nicarbazin, Salinomycin, Eimeria sp., injury score, broilers
