Salinomicina e semduramicina associadas em diferentes concentrações no controle da eimeriose em frangos de corte Salinomycin and semduramicin in different concentrations on the broilers eimeriosis control

Abstract

O presente estudo teve por objetivo investigar a associação de salinomicina e semduramicina, em diferentes doses, frente à infecção mista controlada de Eimeria acervulina, E. maxima e E. tenella em frangos de corte. Oitocentas aves foram divididas em 5 grupos (T1: ração não medicada; T2: 30 ppm de salinomicina e 12,5 ppm de semduramicina; T3: 30 ppm de salinomicina e 15 ppm de semduramicina; T4: 40 ppm de salinomicina e 12,5 ppm de semduramicina e T5: 40 ppm de salinomicina e 15 ppm de semduramicina) e inoculadas aos 15 dias de idade com oocistos esporulados de E. acervulina, E. maxima e E. tenella, em inóculo misto, via ração. Parâmetros produtivos e escore de lesões foram registrados. Todos os grupos tratados apresentaram estatisticamente melhores ganhos de peso cumulativo aos 21 dias de vida. Aos 35 dias de vida, somente o grupo T3 apresentou diferença significativa. A conversão alimentar cumulativa apresentou diferença estatística nos grupos T4 e T5. O tratamento T5 foi mais eficaz no controle de E. tenella. T3 e T5 obtiveram diferenças estatísticas no escore médio de lesão das três espécies. O uso de salinomicina, associada a semduramicina, em baixas doses demonstrou uma opção viável no controle da coccidiose neste experimento.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.
