Objective: Survey of antibiotic effects on serological titer of Mg and Ms infected broiler breeders.
Design: Observational study.
Animals: A total of 42 ross broiler breeders.
Procedure: Thirty-six broiler breeders at 35 weeks old from an infected (Mg and Ms positive) poultry unit and six broiler breeders from a non-infected (Mg and Ms negative) poultry unit were kept in separated cages as recommended in Ross broiler breeder catalogue at the hospital of veterinary faculty of Urmia university. Blood samples were collected from broiler breeders in order to determine serological titers using rapid plate serum agglutination test (RPSAT) and ELISA. before and after administration of lincospectin. tiamulin, tylosin, ciprofloxacin and enrofloxacin antibiotics for five days with recommended dosages of each antibiotics.
Statistical analysis: SPSS statistical analysis program using ANOVA and Two tailed pair t-test were used to analyze the data. Results: The ELISA titers of the infected birds (within and among the groups) were differed significantly (P
