摘　　要：试验旨在研究乳酸菌液体发酵饲料对育肥猪养分表观消化率、粪样菌群、血液生化指标和生产性能的影响。选择200头体重60kg左右的三元杂交猪,随机分为4组,每组5个重复,每个重复10头猪。对照组饲喂基础日粮,试验组饲喂添加10%、30%、50%的乳酸菌液体发酵饲料替代基础日粮中相应比例的全价配合饲料。结果表明,在育肥猪的饲料中添加乳酸菌液体发酵饲料,粗蛋白质、粗纤维、粗脂肪、钙、总磷、氮的养分表观消化率显著提高(P<0.05);鲜粪中大肠杆菌和沙门氏菌的数量显著降低,乳酸菌的数量显著增加(P<0.05);显著提高了血液中总蛋白、白蛋白、免疫球蛋白A、免疫球蛋白G、葡萄糖的含量(P<0.05),显著降低了血液中尿素氮的含量(P<0.05),总胆固醇、三酰甘油、免疫球蛋白M无显著影响;平均日增重和平均日采食量明显增加(P<0.05),料肉比显示添加10%乳酸菌液体发酵饲料饲料报酬为最佳;显著降低了育肥猪发病率(P<0.05)。The purpose of this experiment was to investigate the effects oflactobacillus liquid fermented feed on apparent digestibility of nutrients, fecal microflora, blood biochemical indicators and production performance of fattening pigs. A total of 200 Duroc × Large White × Landrace pigs with average body weight of 60 kg were selected and randomly assigned into 4 groups with 5 replicates of 10 pigs per group. The control group was fed with basic diet, while the experimental group was fed with 10%, 30% or 50%lactobacillus liquid fermented feed replaced by the corresponding proportion of full-price formu. la feed in the basic diet. The results showed that the apparent digestibility of crude protein, crude fiber, crude fat, calcium, total phosphorus and nitrogen was increased significantly (P<0.05), the number of Escherichia coli andSalmonella in fresh manure was decreased significantly, and the number oflactoba. cillus was increased significantly (P<0.05) in the experimental groups. The contents of total protein, al. bumin,immunoglobulin A, immunoglobulin G and glucose in the solution (P<0.05) were also increased and the content of urea nitrogen in the blood was decreased (P<0.05), but there was no significant differ. ence in the contents of total cholesterol, triglycer. ide and immunoglobulin M;the average daily gain and average daily feed intake were increased significantly (P<0.05), and the ratio of feed to meat was also increased significantly (P<0.05). Results from feed-to-meat ratio showed that addi. tion of 10% lactobacillus liquid fermented feed had the best feed reward rate.The disease incidence of fattening pigs was significantly reduced (P<0.05).
