Exposure to plant-oriented microbiome altered jejunal and colonic innate immune response and barrier function more strongly in suckling than in weaned piglets.

ABSTRACT: Weaning often leaves the piglet vulnerable to gut dysfunction. Little is known about the acute response of a gut mucosa primed by a milk-oriented microbiome before weaning to a plant-oriented microbiome (POM) after weaning. We evaluated the epithelial structure, secretory response and permeability in the small and large intestines of piglets receiving a milk-based (i.e., preweaning) or plant-based diet (i.e., postweaning) to POM inocula using intestinal loop perfusion assays (ILPA). The POM were prepared from jejunal and colonic digesta of four 7 week-old weaned (day 28 of life) piglets, having gut-site specific microbial and metabolite composition. Two consecutive ILPA were performed in 16 piglets pre- (days 24 to 27) and 16 piglets postweaning (days 38 to 41) in two replicate batches. Tw
