Sažetak
In order to assess the effect of tiamulin in the control of Mycoplasma (M) synoviae in the first place and of some bacterial infections, a field trial has been conducted in a broilerfarm. Tiamulin eas administred in drinking water at a 0, 0025% level for three days and again at the age of 21 days. Its effect was compared with the effect of the combination of tiamulin (0, 0125%) and oxytetracycline, tiamulin and trimetosul respectively. Control group od chickens was not given any drug. All chickens were vaccinated against Gumboro and Newcastle diesase at age of 21, 14 days respectively. Chickens were the progeny of breeding layers in which the infection with M. synoviae was diagnostified by serum plate agglutination test (SPA) and enzyme- linked immunosorbent assay (ELISA). In 120 serum samples SPA test revealed 100% of positive sera and specific titres of different values were found by ELISA test. Positive finding of antibodies to M. synoviae was frequently found in fattening chickens. Mortality rate, feed consumption and weight gain were monitored during the trial and meet quality evaluated at the end of the trial. Laboratory tests revealed the presence of bacteria in parenchymal organs of dead birds.Serological tests (SPA, ELISA, haemagglutination inhibition) were used to determine the specific antibodies to M. synoviae and M. gallisepticum ant to Newcastle disease. The effect of the combination of tiamulin, either with oxytetracycline or trimetosul, showed to be superior to the effect of tiamulin alone. Such findings was expected because of the concurent presence of bacterial infection induced by pathogenic strains of E. coli and S. enteritidis.
