摘　　要：本试验旨在研究植物乳杆菌对肉鸡生长性能和血清生化指标的影响,以探讨植物乳杆菌作为生长促进剂及疾病治疗剂的可能性及其适宜的添加剂量。采用2×3复因子试验设计,即大肠杆菌O78攻毒与未攻毒2个处理和植物乳杆菌3个添加水平（0、0.8‰、1.6‰）,选用180只AA肉鸡,随机分为6组,每组3个重复,每个重复10只。试验期42d,分为前期（1~21d）和后期（22~42d）。结果表明,攻毒后1~42日龄肉鸡平均日增重（ADG）显著降低（P〈0.05）,料重比（F/G）显著升高（P〈0.05）,同时21日龄肉鸡血清AST、ALT、ALP和BUN水平显著升高（P〈0.05）,TP、GLB水平显著降低（P〈0.05）,42日龄肉鸡血清ALB、AST、ALT和ALP水平显著升高（P〈0.05）;日粮中添加植物乳杆菌能提高1~42日龄肉鸡ADG,降低ADFI、F/G,同时可显著提高21日龄攻毒肉鸡血清TP、ALB、GLU水平及42日龄攻毒肉鸡血清TP、GLB水平（P〈0.05）,显著降低21日龄攻毒肉鸡血清ALP、BUN水平及42日龄攻毒肉鸡血清ALT、ALP、BUN水平（P〈0.05）;攻毒因素与植物乳杆菌水平因素二者的互作效应对后期（22~42d）肉鸡F/G有显著影响（P〈0.05）,对21日龄肉鸡血清ALB、GLU、ALP及42日龄肉鸡血清ALT、ALP有极显著影响（P〈0.01）。综上所述,植物乳杆菌能提高肉鸡的生长性能,改善血液生化指标,且添加1.6‰植物乳杆菌的总体效果均优于0.8‰的添加量,可以考虑将其作为一种新型的替代抗生素的微生态制剂。The main aim of the current experiment was to study the effect of Lactobacillusplanta rum 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 2×3factorial arrangement of treatments with 2 management（wheather infected with E.coli O78 or not）and 3levels of Lactobacillus plantarum（0,0.8‰ and 1.6‰）,a total of 180 AA broilers were randomly allotted to 6groups with 3replicates per group and 10 broilers per replicate.The whole experiment period was42 days,including two phase of days 1to 21（starter period）and days 22 to 42（finisher period）.The results showed that after E.coli O78 infected,the ADG was significantly decreased（P0.05）and the F/G was significantly increased（P0.05）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（P0.05）,serum TP and GLB levels at day 21 were significantly decreased（P0.05）.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（P0.05）,serum ALP and BUN levels at day 21 and serum ALT,ALP and BUN levels at day 42 after infection were significantly decreased（P0.05）.The interaction between infected factor and Lactobacillus plantarumlevel factor was significant in the F/G at finisher period（P0.05）,and extremely significant in the serum ALB,GLU and ALP levels at day 21 and serum ALT and ALP levels at day42（P0.01）.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.
