الملخص EN

The objective of the present study was to evaluate the effect of E.

coli on serum biochemistry and to determine the preventive effect of adding marjoram as growth promoters in 2 concentrations (0.5% &1%/kg ration) on serum biochemistry.

This study was carried out on 150 one day- old chicks to evaluate the effect of dietary supplementation of 0.5 and 1% origanum majorana for 6 weeks on broilers and the possibility of facing the experimental infection with E.

coli O78.

In treated groups with marjoram 1%, biochemical results revealed increase in the total protein and total globulin and decrease in AST, ALT and uric acid in 4th and 6th weeks of the experiment.

In addition to significant decrease in serum cholesterol, triglyceride, LDL and increase in HDL, while, serum albumin showed non-significant changes compared to control group.

Regarding to the infected group and group infected and treated with 0.5% marjoram, increased total protein, total globulin, AST, ALT, glucose, cholesterol and uric acid were observed
