Резюме: Bovine respiratory disease (BRD) is one of the most common and economically important disease affecting feedlot industry throughout the world. The economic significance of this condition are high morbidity and mortality, decreased weight gains, reduced food utilization, low meet quality and additional therapeutic and prophylactic measures. The hypothesis of this study was that the use of metaphylactic protocol based on the risk to develop BRD would reduce morbidity and mortality. For this purpose, the aims of this study were to evaluate the effect of tildipirosin on the incidence of BRD in feedlot cattle. A total of 106 male beef calves were enrolled in the study. Calves were allocated randomly in control group (54 animals) and treatment (52 animals) group. The first group received subcutaneous injection of placebo while the second was treated with SC injection of tildipirosin. The observed BRD incidence was 35.2, and 9.6% for the calves in the control and treatment group, respectively (P = 0.012). These results suggest that the tildipirosin metaphylaxis tend to decrease the incidence of BRD in the first four weeks of the fattening period in beef cattle. In conclusion, metaphylactic protocols, based on the administration of tildipirosin in the high risk period can be used for management of BRD.
