The aim of this study was to evaluate dietary effects of chlorogenic substances (Igusafe) on growth performance, intestinal microflora population and serum biochemistry in broilers. A total of 144 Ross 308 one-day-old male broiler chicks were randomly allocated to 3 treatment groups consisting of 8 replications of 6 chicks per pen for 42 days. There treatments were used: chicks were fed by basal diet as control group, basal diet plus 80 mg Igusafe/kg diet, and basal diet and 160 mg Igusafe/kg diet. Results showed that the addition of 80 mg Igusafe to the diet resulted in significantly higher body weight gains and lower aspartate amino transferase (AST) and serum total protein (TP) concentrations compared with control group (P<0.05). Intestinal tract weight was also significantly higher in the group fed 160 mg Igusafe/kg diet (P<0.05). Supplementing both levels of Igusafe significantly reduced Escherichia coli count (P<0.05). There were no treatments effects on carcass yield, liver weight and Lactic acid bacteria population (P>0.05). In conclusion, our results indicated that supplementation of Igusafe may be useful as enhancer of growth performance by reducing Escherichia coli count with a positive trend to decrease the broilers mortality.
