The experiment was conducted in two phases. During phase I one hundred broiler chicks were divided into A,B, C and D groups having twenty five birds in each and were injected gantamicin sulphate in the form of gentalin 5% intramuscularly at the rate of 5mg/kg, lOmg/ kg, 20mg /kg in groups A,B and C twice daily for four days respectively while group D kept as control. During phase II twenty five chicks were divided into groups E,F,G,H and I having five birds in each. Birds in groups E and F were injected gentalin 5% intramuscularly at the rate of 40mg/kg and 80 mg/kg while gantamicin sulphate injected in the form of Aagent 10% at the rate of 40 mg / kg and 80 mg/kg to groups G and H twice daily for four days respectively and the birds of I group were kept as control.
Blood samples (3m1) were collected from all medicated and un-medicated groups before and after medication on different days and serum was separated for the measurement of different biochemical parameters. Post-mortem examination of all birds were performed at the end of experiment. Post-mortem examination revealed no abnormality in any bird during phase I (normal organs) while during phase II abnormalities such as congestion, inflammation of the kidney and necrosis, discoloured livers were recorded except control group. Six birds died during experiment in phase 11(2/10 at 40mg/kg and 4/10 at 80mg/kg dose). The mortality rates at 40 mg/kg and 80 mg/kg were 20 and 40% respectively. An increase in Aspartate amino Transferase was observed in medicated birds during phase I while a significant increase in Aspartate amino Transferase, Alanine amino Transferase, uric acid and creatinine were recorded in medicated birds during phase II. From this study it is concluded that broiler birds tolerated gentamicin upto 20mg/kg while acute toxic effects at the dose of 40mg/kg and 80mg/kg of gentamicin were recorded in broiler chicks. No sign of visceral gout were recorded in any bird. There was no difference in the toxicity of two different preparations of gentaniicin.
