Abstract

This study was conducted to investigate the potential effect of effective microorganisms (EM) on some biochemical parameters which includes; glucose, cholesterol and triglycerides levels in addition to the levels of Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) in the serum of broilers. 50 One day-old unsexed broiler chicks were randomly assigned in to two treatments (25 chick/pen); control group (T1) and treatment group (T2) which supplied with 1% EM (10 ml/litre) to the drinking water for 5 weeks of age. Results showed that inclusion of 1% EM significantly increase blood glucose (P<0.05) and lower cholesterol but the triglycerides decrease was insignificant in (T2) than those of (T1). On the other hand (AST) increased significantly (P<0.05) in (T2) as compared to the (T1). It can be concluded from this study that EM supplementation may have some beneficial effect by lowering cholesterol and triglycerides on the other hand it may cause some tissue damage as indicated by increasing levels of (AST), these results need to be studied using different types and doses of EM.
