fructooligosaccharide and Intestinal-Diseases

Perinatal nutrition programs physiologic and metabolic functions, with consequences on the susceptibility to develop metabolic diseases in adulthood. The microbiota represents a key factor of such programming. We investigated whether perinatal prebiotic [short-chain fructooligosaccharides (scFOS)] supplementation improved adult metabolic health in association with microbiota changes in pigs used as human model. Sows were supplemented with scFOS or not during the end of gestation and the entire lactation, and offspring received scFOS accordingly during 1 mo after weaning. Pigs were then fed a standard diet for 5 mo, followed by a high-fat diet for 3 mo once adults. Perinatal scFOS supplementation induced a persistent modulation of the composition of the fecal microbiota in adulthood, notably by increasing the Prevotella genus. Meanwhile, scFOS animals displayed improved capacity to secrete glucagon-like peptide-1 and improved pancreas sensitivity to glucose without any changes in peripheral insulin sensitivity. Perinatal scFOS supplementation also increased ileal secretory IgA secretion and alkaline phosphatase activity and decreased TNF-α expression in adipose tissue. In conclusion, perinatal scFOS supplementation induced long-lasting modulation of intestinal microbiota and had beneficial consequences on the host physiology in adulthood. Our results highlight the key role of perinatal nutrition on later microbiota and host metabolic adaptation to an unbalanced diet.-Le Bourgot, C., Ferret-Bernard, S., Apper, E., Taminiau, B., Cahu, A., Le Normand, L., Respondek, F., Le Huërou-Luron, I., Blat, S.

Short-chain fructooligosaccharides (FOS) were supplemented to the diets of nine quarter horses ranging in age from 489 to 539 d with initial BW averaging 400.6 +/- 21.2 kg. The objectives of this study were to determine the effects of dietary FOS on the fecal responses in terms of pH, the microbial population, and VFA concentrations. The horses were used in a 3 x 3 replicated Latin square design, fed according to NRC requirements, and their individual diets were supplemented with no FOS (CON), 8 g of FOS/d (LOW), or 24 g of FOS/d (HIGH) over three 10-d feeding periods. On the last 3 d of each 10-d feeding period, a single fecal sample was collected between 0730 and 0930. Fecal pH decreased linearly (P = 0.01) from 6.48 with the CON diet to 6.38 with the HIGH diet, but there was no change (P = 0.19 for linear effect) in fecal consistency among treatments. A quadratic effect (P < 0.01) was observed for fecal Escherichia coli population, but no difference (P = 0.88 for linear effect) was found in fecal Lactobacilli enumeration among treatments. The presence of fecal Bifidobacteria was unable to be confirmed and was therefore not reported. Fecal acetate concentrations increased linearly (P = 0.03), with means of 2.13, 2.18, and 2.52 mg/g of wet feces for CON, LOW, and HIGH treatments, respectively. Similarly, fecal propionate concentrations increased linearly (P = 0.01), with means of 0.58, 0.64, and 0.73 mg/g for CON, LOW, and HIGH treatments, respectively. Fecal butyrate concentrations also increased linearly (P = 0.02), with means of 0.40, 0.46, and 0.54 mg/g for CON, LOW, and HIGH treatments, respectively. Total VFA (P = 0.01) and lactate (P = 0.02) concentrations increased linearly, with total VFA means of 3.47, 3.69, and 4.25 mg/g for CON, LOW, and HIGH treatments, respectively, and lactate means of 0.36, 0.41, and 0.47 mg/g for CON, LOW, and HIGH treatments, respectively. Supplementing FOS in diets fed to yearling horses altered fecal microbial populations, fecal VFA concentrations, and pH.
