Table 2 The application of probiotic L. reuteri in pigs

From: Study and use of the probiotic Lactobacillus reuteri in pigs: a review

Strain Dose Animal Significant results Reference
L. reuteri I5007 6 × 109 CFU/d newborn piglets increased average daily gain; reduced diarrhea incidence; affected the colonic microbial communities , in particular, reduced numbers of Clostridium sp; reduced mRNA expression of IL-1β in the ileum [46]
L. reuteri I5007 2× 109 CFU/d weaned pigs increased weight gain and feed conversion; decreased the occurrence of diarrhea; enhanced T-cell differentiation and induced cytokine expression in the ileum [47]
L. reuteri I5007 2× 109 CFU/d weaned pigs had faster growth and higher feed intakes; improved the anti-oxidative defence system and alleviated damage caused by diquat [50]
L. reuteri I5007 5.8 × 107 CFU/g weaned pigs increased weight gain, feed intake and apparent crude protein digestibility; increased serum specific anti-OVA IgG level [52]
Lactobacilli complex 105 CFU/g weaned pigs increased weight gain and feed intake compared with carbadox; prevented diarrhea; decreased E. coli and aerobe counts, increased Lactobacilli and anaerobe counts in digesta and mucosa [16]
L. reuteri BSA131 2× 106, 2× 108 CFU/g weaned pigs improved weight gain and feed conversion; decreased the number of enterobacteria in the feces [12]
L. reuteri X-1 108 CFU/g weaned pigs improved weight gain and feed conversion; decreased serum IgG and IgM concentrations, incresed serum DAO and D-lactate concentrations [51]
L. reuteri I5007 1.02 × 108 CFU/g growing pigs increased total antioxidant capacity [35]
L. reuteri I5007 108 CFU/g weaned pigs increaed weight gain, neither body weights nor weight gains differed between the L. reuteri and aureomycin groups; alleviated weaning stress syndrome [48]
L. reuteri and L. plantarum complex 106 CFU/g weaned pigs increased apparent total tract digestibility of nitrogen, gross energy, and fecal Lactobacillus concentration; decreased fecal gas emission, diarrhea score, and E. coli concentration [78]
L. reuteri 3S7 and L. plantarum 4.1 1010 CFU/d sows and piglets were found in the faeces; decreased the population of Enterobacteriaceae; decreased β-glucuronidase activity of all pigs [79]
  1. Note: L. reuteri I5007 was initially known as L. fermentum I5007.
  2. Lactobacilli complex including L. gasseri, L. reuteri, L. acidophilus and L. fermentum (renamed L. reuteri I5007).
