Abstract

The effect exerted by overdosage of monensin, an ionophore antibiotic, on the lipid peroxide status of broiler chickens was studied. Three-week-old broiler cockerels were given 150 mg monensin/kg body mass through a tube, and the malondialdehyde (MDA) concentration, glutathione peroxidase (GSH-Px) and catalase activity of the liver and breast muscle, and MDA concentration and GSH-Px activity of the blood plasma were determined. Liver MDA and catalase values rose rapidly and significantly during the experimental period. GSH-Px activity initially decreased, then tended to rise. Blood plasma and breast muscle variables did not change during the experiment. Acute monensin poisoning induced substantial enhancement of lipid peroxidation processes in the liver, while it did not appreciably affect the lipid peroxide status of the blood plasma and breast muscle. The role of the observed phenomenon in the rather complex pathogenesis of monensin poisoning is not known sufficiently. Further studies are needed to elucidate the problem.
