从猪粪便中分离出的乳杆菌菌株的益生菌潜力被评估为仔猪中的益生菌。检查该菌株对 pH 2.0、0.5% 牛胆汁和抗生素的耐药性，以及对肠道致病菌的抗菌活性。通过饲料给 25 头 1 个月大的长白仔猪施用益生菌菌株罗伊氏乳杆菌 BSA131。将仔猪分为五组，每组五只仔猪，并用不同的饲料喂养 28 天。将罗伊氏乳杆菌 BSA131 的每日消耗量按 10(6) 或 10(8) 冻干细菌的浓度分为两组。在食用前、食用期间和食用后收集粪便样本。测定粪便样本中的乳酸杆菌和肠杆菌细胞计数。每天记录仔猪的活重增加和饲料消耗。这项研究表明，菌株 BSA 131 提高了仔猪的增重和饲料转化率。它还显示粪便样本中乳酸菌细胞计数显着增加，而肠杆菌数量显着减少。 BSA 131 菌株被认为是仔猪的潜在益生菌，尤其是断奶后。
The probiotic potential of a Lactobacillus strain, isolated from pig faeces, was assessed as a probiotic in piglets. The strain was examined for resistance to pH 2.0, 0.5% oxgall and antibiotics, and antimicrobial activities against enteric pathogenic bacteria. The probiotic strain, L. reuteri BSA131, was administered through the feed to 25 1-month-old Landrace piglets. The piglets were divided into five groups of five piglets each and fed with different diets for 28 days. The daily consumption of L. reuteri BSA131 was assigned into two groups by the concentration of 10(6) or 10(8) freeze-dried bacteria. Fecal samples were collected before, during, and after consumption. Lactobacilli and enterobacteria cell counts were determined in the fecal samples. The liveweight gains and feed consumption of the piglets were recorded daily. This study showed that strain BSA 131 enhanced liveweight gains and feed conversion rates in piglets. It also showed a significant increase in lactobacilli cell counts and decreases in enterobacterial numbers in the fecal samples. Strain BSA 131 was considered to be a potential probiotic for piglets, especially after weaning.
