Résumé

Perinatal nutrition, a key factor controlling gut bacterial colonization, may have lasting consequences on health. We investigated whether early short-chain fructooligosaccharide (scFOS) supplementation, known to well-balance microbiota, impacted adult metabolic and immunologic responses to a high-fat (HF) diet. Sows received a supplementation with scFOS or not for the last 4 weeks of gestation and the lactation. The scFOS supplementation was maintained in piglets weaned from scFOS sows till postnatal day (PND) 56. Twenty four piglets were then fed a standard diet until PND190, then a HF diet for 12 weeks. Early scFOS supplementation increased faecal short-chain fatty acid production after 3 weeks of HF diet but this effect was not observed later. Ongoing metagenomics analysis will give more insights on microbiota composition changes. Insulin response to a glucose challenge (IVGTT) tended to increase in scFOS group, but no other metabolic parameter was modified (lipid metabolism, basal glycaemia and insulinemia, insulin pancreatic content). Preliminary results showed a modulation of the pro-inflammatory cytokine secretion (IFNg , TNFa, IL-8) by ex vivo stimulated ileal explants and MLN cells, revealing a modification of local immunity orientation with perinatal scFOS supplementation. Our results underline the key role of early microbiota modulation on adult responses to a nutritional challenge.
