This study aimed to investigate the association of salinomycin and semduramicin, in different doses, against controlled mixed infection of Eimeria acervulina, E. maxima and E. tenella in broiler chickens. Eight hundred birds were divided into 5 groups (T1: not medicated feed; T2: 30 ppm of salinomycin and 12.5 ppm of semduramicin; T3: 30 ppm of salinomycin and 15 ppm of semduramicin; T4: 40 ppm of salinomycin and 12,5 ppm of semduramicin and T5: 40 ppm of salinomycin and 15 ppm of semduramicin) and inoculated at 15 days of age with sporulated oocysts of E. acervulina, E. maxima and E. tenella in a mixed suspension, through the feed. Performance data and lesion scores were recorded. All treated groups showed statistically better cumulative weight gain at 21 days old. At 35 days old only the T3 group showed significant difference. Cumulative feed conversion showed statistical difference in the groups T4 and T5. The treatment T5 was more effective in the coccidiosis control of E. tenella. T3 and T5 achieved statistical differences in the average lesion scores of the three analyzed species. The association of salinomycin and semduramicin used in lower doses than the usual, showed to be an option in the coccidiosis control in this experiment. |
