Abstract

Objective: To investigate the effect of fosbac on some blood biochemical variables in broilers. Methods: Fosbac with the dose of 160 and 320 mg/kg was added to drinking water of poultry for 5 days. For each dose, a separate control group was considered. Blood samples were collected 1 day post treatment (four groups of eight 20-day-old broilers) in the first experiment, and after 7 days post treatment (another four groups of eight 20-day-old broilers) in the second experiment. The serum aspartate aminotransferase, lactate dehydrogenase, alkaline phosphatase activity, uric acid, creatinine and urea concentrations were measured using routine laboratory methods. Results: The results of this study showed that oral fosbac caused no significant effect on important liver and kidney function parameters. Conclusions: It can be concluded that this antibiotic can be used safely in broilers.
