Effects of concurrent oral administration of monensin and selenium on some haematological and biochemical parameters in broiler chickens.

Monensin and selenium (sodium selenite) at different toxic levels were administered orally to the broiler chickens for variable periods. A depression in haematological parameters and biochemical ones such as alanine and aspartate aminotransferase, serum total protein and cholesterol were recorded in acute and subacute toxicosis of these substances. The present experiments led to the conclusion that concurrent administration of selenium and monensin at toxic levels resulted in exasperated toxic response in broiler chickens which in turn had been produced by embellishment of toxicosis inducing properties of both examined substances.
