This experiment was conducted to investigate the effect of dietary single or mixed supplementation of plant extract, fermented medicinal plants and Lactobacillus on performance, nutrient availability, blood characteristics, cecal microflora and intestinal digestive enzymes activity in broiler chickens and to prove the possibility of plant derived compounds and Lactobacillus as an antibiotic growth promoter alternative. A total of eight hundred forty, 1-d-old male broiler chicks (Ross strain) were randomly divided into 7 groups with 4 replicates of 30 birds each. The treatments were NC (antibiotic-free diet), PC (basal diet with 0.05% antibiotics and 0.03% anticoccidials), PE (basal diet with 0.1% plant extract), FMP (basal diet with 0.1% fermented medicinal plants), LB (basal diet with 0.1% probiotics), PE+LB (basal diet with 0.1% plant extract and 0.1% probiotics) and FMP+LB (basal diet with 0.1% fermented medicinal plants and 0.1% probiotics). The final body weight, body weight gain and feed conversion rate in all treated groups tended to be improved or significantly improved as compared to those of NC (P<0.05). PE was significantly high in the final body weight, body weight gain of all treated groups (P<0.05). But the growth performance was significantly lower in all treated groups except PE than PC (P<0.05). No synergic effect in growth performance was found when plant extracts and Lactobacillus were mixed and fed to broilers. The ratio of albumin to globulin was significantly lower in all groups than NC (P<0.05). And the stress indicator (lymphocyte/heterophil ratio) of NC was significantly reduced than other treatments (P<0.05). No significant differences were observed on the numbers of cecal microbes and Lactobacillus. The number of cecal E. coli and Salmonella in FMP and LB were significantly reduced (P<0.05). The activity of intestinal digestive enzymes except to sucrase of treated groups significantly decreased compare to those of controls (P<0.05). These results suggest the possibility that plant extracts and Lactobacillus could be used as the alternative of antibiotic growth promoters by improving the performance of broiler chicks.
