[Clinical and hematological changes after olaquindox poisoning in fattening pigs].
A pig grower ration containing olaquindox at a concentration of 778 mg/kg was accidentally fed to 10 respectively 16 weeks old weaner pigs. The subsequent intoxication was characterized by poor growth and long-term disturbances of renal function and electrolyte metabolism. A deficiency of aldosterone, produced by a selective degeneration of the arcuate zone of the adrenal cortex, is probably the cause of the hyponatremia, hyperkalemia and hemoconcentration observed. Simultaneously plasma levels of urea and creatinine were elevated five- to eightfold. Due to hyperkalemia episodes with collapse, paralysis and severe electrocardiographic changes occurred several times. Two pigs died in the course of such attacks. Individuals, which transiently showed distinct clinical symptoms of intoxication, did not show any signs of disease 15 or 18 weeks later. Therefore it may be assumed, that the lesions of the adrenals, heart and skeletal muscle caused by olaquindox intoxication are reversible in some cases.
