Abstract

Daily oral administration of two dose levels of 1 and 2 mg/kg body mass of ampicillin (groups A1 and A2), 50 and 100 mg/kg body weight of oxytetracycline (groups O1 and O2) and 50 and 100 mg/kg body mass sulphadimidine (groups S1 and S2), in broiler feed resulted in an immediate increase in concentrations of antibiotics in plasma and tissues from day 1 until day 40 of the treatment. At day 40 a range of 0.61 to 1.94, 0.24 to 2.25, 1.30 to 6.70 μg/g or μg/ml of A, O and S, respectively was found in tissues or plasma. Withdrawal of medicated feed resulted in a rapid decline in tissue concentration parallel to that of plasma, and withdrawal times were 5 days for (O) and (S) and 6 days for (A).
