摘　　要：试验旨在探究3种微生态制剂(草本复合微生态剂、猪源性乳酸菌复合微生态剂、多种芽孢杆菌复合微生态剂)对猪生长性能、肉品质、粪便菌群的影响。选择168头体重相近的猪(公、母各半),随机分为4组,试验组每组8个重复,对照组(DZ组)4个重复,每个重复6头猪。对照组猪饲喂基础日粮,QC组猪饲喂基础日粮+0.50%复合草本微生态制剂,XW组猪饲喂基础日粮+0.10%猪源性乳酸菌微生态制剂,YLD组猪饲喂基础日粮+0.05%多种芽孢杆菌复合微生态制剂。试验期126 d。结果表明,与对照组相比,3种微生态制剂均能够极显著降低猪的死亡率(P<0.01),提高平均日增重,提高肉的比色评分,降低剪切力。草本复合微生态剂、猪源性乳酸菌复合微生态剂降低了料重比,猪源乳酸菌复合微生态制剂改善了猪胴体斜长;3种微生态制剂均可降低Chao指数、Ace指数、Shannon指数,提高Simpson指数。研究表明,3种微生态制剂对猪生长性能均具有促进作用,草本复合微生态制剂能够较好地改善猪肉品质,猪源性乳酸复合微生态制剂能够较好地提升胴体性状。3种微生态制剂对粪便丰度指数、多样性指数及菌群结构具有一定影响。The study was to explore effect of adding three kinds of microbial ecological agents(herbal compound microecological agent,porcine lactic acid bacteria compound microecological agent,multiple Bacillus compound microecological agent)on growth performance,meat quality and fecal microbiota of pigs.A total of 168 pigs with similar body weight,half in male and female,were randomly divided into four groups,experimental group had eight replicates in each group,control group(DZ group)had four replicates,with six pigs in each replicate.Pigs in control group were fed with basal diet,pigs in QC group were fed with basal diet+0.50%herbal compound microecological agent,pigs in XW group were fed with basal diet+0.10%porcine lactic acid bacteria compound microecological agent,and pigs in YLD group were fed with basal diet+0.05%multiple Bacillus compound microecological agent.The experiment lasted for 126 d.The results showed that compared with control group,adding three kinds of compound probiotics extremely reduced mortality rate of pigs(P<0.01),increased average daily gain and colorimetric score,decreased shear force.Herbal compound probiotics and porcine lactic acid bacteria compound microbiotics decreased F/G,porcine lactic acid bacteria compound microbiotics improved carcass oblique length.The three probiotics also decreased Chao index,Ace index and Shannon index,increased Simpson index.The experiment indicates that three kinds of compound probiotics can improve growth performance of pigs,herb compound probiotics are effective in improving meat quality,probiotics of porcine lactic acid bacteria are effective in improving carcass character of pigs.Three kinds of microbial ecological agents have a certain impact on fecal abundance index,diversity index and microbial community structure.
