Protective Effect of Peppermint on the Toxicity Induced by Blue Green Algae in Poultry

Abstract

This study was done on 5 groups of poultry chicks from one day up to 45 days of age. We usedblue green algae as source of feed additives added to the water and ration in addition to peppermintto evaluate the protective effect of peppermint against the toxicity induced by the blue green algae.The administration of blue green algae in chicken food and water caused hepato- and cardio toxicityindicated by significant increase in liver (ALT and AST) and heart enzymes (CK and LDH) and decreasein MDA and CAT. The algae showed histopathological alterations in the liver in form of congestion inthe central vein, degeneration in the hepatic cords and circumscribed areas of lymphocytic infiltrationsbetween the hepatic cords. While it was mild in heart tissues as it showed also lymphocytic infiltrationand congestion of myocardial blood vessels. The biochemical parameters were corrected except the CKand LDH. The histopathological alterations were corrected by the addition of peppermint.
