[Nitrofuran poisoning in veal calves].

Prolonged administration of furazolidone to calves may give rise to chronic furazolidone poisoning: retardation of growth, thrombocytopenia and leucopenia, occasionally changing into haemorrhagic diathesis. In acute nitrofuran poisoning neurological signs are observed as a consequence of monoamine oxidase inhibition. Five incidents of acute nitrofuran poisoning on veal calf farms are reported in the present paper, each with a mortality rate varying frm 46.7 per cent ot 70 per cent. Ten times the recommended dose of furazolidone or furadoltone was administered in each case.
