Abstract
Intramuscular administration of 5 mg/kg conventional and 10 mg/kg long-acting oxytetracycline to camels have produced serum concentration of more than 1 mu g/ml oxytetracycline. Both formulations have significantly reduced concentration of total protein, albumin, globulin and lysosomal enzymes in treated animals compared to control. The formulations also reduced leukocyte, lymphocyte and neutrophil count. It is suggested that chronic administration of oxytetracycline may produce an immunosuppression in camels.
