Transplantation of fecal microbiota from different breeds improved intestinal barrier condition and modulated ileal microflora of recipient pigs.

In this study, we investigated the effects of transplanting Ningxiang pig fecal bacteria on the ileum microflora and intestinal barrier of Duroc × Landrace × Large White (DLY) pigs. Thirty-two DLY pigs at 90-d-old were equally assigned to either control groups (fed the basal diet) or test groups (fed the basal diet + 10 mL fecal microbiota suspension from Ningxiang pig). Results showed that fecal microbiota transplantation (FMT) did not influence the growth performance, but increased the number of ileum goblet cells and the expression level of mucin-2.
