Abstract: The effects of effective microorganisms (EM) on the Egg production traits, Egg quality and egg chemical analysis of layers were studied. Five hundred and forty Inshas layers (a local Egyptian chicken strain) were randomly divided into 6 groups with 90 layers in each group. Layers in group 1 were fed a control diet. The remaining groups received the control diet that contained 2.5, 5.0, 7.5 or 10.0 ml of EM/ kg, and 20 mg of zinc bacitracin/kg respectively. The obtained results clarified improvements
in egg production ( Egg number and Egg mass/ hen) and Egg quality ( (P < 0.01) of layers when EM was added to the diets. The results also showed that, egg yolk cholesterol was significantly decreased in chicks that fed diets with different levels of EM as compared with the control diet, while egg protein percentage was significantly (p<0.05) increased in birds fed diets with different levels of EM.
