Abstract: The main aim of the current experiment was to study the effect of Lactobacillus plantarum on growth performance and serum biochemical indices of broilers,investigated the possible of using Lactobacillus plantarum as growth accelerant and therapeutic agent and the appropriate adding quantity.The experiment was conducted as a 2×3 factorial arrangement of treatments with 2 management (wheather infected with E.coli O78 or not) and 3 levels of Lactobacillus plantarum (0,0.8‰ and 1.6‰),a total of 180 AA broilers were randomly allotted to 6 groups with 3 replicates per group and 10 broilers per replicate.The whole experiment period was 42 days,including two phase of days 1 to 21 (starter period) and days 22 to 42 (finisher period).The results showed that after E.coli O78 infected,the ADG was significantly decreased (P <0.05) and the F/G was significantly increased (P <0.05) during the whole period,serum AST,ALT,ALP and BUN levels at day 21 and serum ALB,AST,ALT and ALP levels at day 42 were significantly increased (P <0.05),serum TP and GLB levels at day 21 were significantly decreased (P <0.05).Supplementation of Lactobacillus plantarum was increased the ADG and decreased the ADFI and F/G during the whole period,serum TP,ALB and GLU levels at day 21 and serum TP and GLB levels at day 42 after infection were significantly increased (P <0.05),serum ALP and BUN levels at day 21 and serum ALT,ALP and BUN levels at day 42 after infection were significantly decreased (P <0.05).The interaction between infected factor and Lactobacillus plantarum level factor was significant in the F/G at finisher period (P <0.05),and extremely significant in the serum ALB,GLU and ALP levels at day 21 and serum ALT and ALP levels at day 42 (P <0.01).In conclusion,Lactobacillus plantarum could increase growth performance and improve some serum biochemical indices of broilers,1.6‰ volume of addition had a better total effect than 0.8‰ volume of addition and could be used as a novel alternative to antibiotics probiotics.
