The studied treatments included as T1: basal diet (control); T2: basal diet included 0.025% prebiotics TechnoMos; T3: basal diet included 0.075% prebiotics TechnoMos; T4: basal diet basal diet included 0.125% prebiotics TechnoMos; T5: basal diet basal diet included 0.05% thyme extract; T6: basal diet included 0.075% thyme extract; and T7: basal diet included 0.10% thyme extract. Microflora populations of cecum and ileum collected and analyzed. Based on obtained results, dietary additive had not significant effect on ileum lactobacillus and cecum Eschericia coli (P>0.05), although control diet (without additive) from 1st-42nd day of age had the lowest ileum lactobacillus numerically (7.35 log CFU/g digesta) and the highest cecum Eschericia coli (8.16 log CFU/g digesta). Also, 0.125% prebiotics TechnoMos and 0.075% thyme extract from 1st-42nd day of age resulted to numerically the highest ileum lactobacillus (7.97 log CFU/g digesta) and lowest cecum Eschericia coli (7.11 log CFU/g digesta). From obtained results, it is showed that dietary additive had significant effect on cecum lactobacillus and ileum Eschericia coli (P≤0.05), so 0.125% prebiotics TechnoMos and 0.075% thyme extract from 1st-42nd day of age had the highest cecum lactobacillus (8.82 log CFU/g digesta) and the lowest ileum Eschericia coli (6.85 log CFU/g digesta).
