“…For instance, Proteobacteria organisms are often associated with inflammatory conditions (46). Our previous study showed that sows fed the KF diet showed increased lactation feed intake (5.81 kg versus 5.39 kg), improved in the number of piglets weaned per litter (9.68 versus 9.50), and weaned piglets of significantly higher litter weight (67.37 kg versus 61.25 kg) than those fed the control diet (9). The addition of KF during gestation could have a substantial financial impact on sow operations.…”

“…Moreover, the transition from pregnancy to lactation is characterized by physiological and metabolic changes, such as a progressive decrease in insulin sensitivity during late gestation and lactation (5,6), which may unfortunately result in decreased lactation feed intake of sows (7,8). Our previous studies showed that sows provided with konjac flour (KF) during gestation significantly increased their voluntary feed intake during lactation and demonstrated improved litter weight at weaning (9)(10)(11), probably as a result of insulin sensitivity improvement. However, the mechanism by which dietary KF exerts the benefit is poorly understood.…”

“…KGM is a complex carbohydrate consisting of D-glucose and D-mannose units joined by ␤-1,4 glycosidic bond linkages (13). KGM has great viscosity and swelling capacity (10) and withstands digestion in the small bowel and has been shown to alter the colonic/fecal microbiota composition in rats (14), adult humans (12), and sows (9). Growing evidence suggests that the gut microbiota plays a vital role in driving metabolic disease development, including inflammation, and reduced insulin sensitivity in nonpregnant (15,16) or pregnant (17) hosts.…”

Although dietary fibers contribute to health and physiology primarily via the fermentative actions of the gut microbiota of the hosts, few studies have focused on how these interactions influence the metabolic status of sows. Here, the effects of inclusion of konjac flour (KF) in a gestation diet on oxidative stress status, insulin sensitivity, and gut microbiota were investigated to elucidate the correlation between the microbiota and metabolic changes in sows. Sows were assigned to either control or 2.2% KF dietary treatment during gestation. The gut microbiota population in sows during gestation and lactation was assessed by 16S rRNA gene sequencing. The oxidative stress parameters, homeostasis model assessment (HOMA) values, and fatty acids in the blood of sows were also assessed. Compared to the control diet group, KF significantly reduced the serum levels of reactive oxygen species (ROS) and 8-hydroxy-deoxyguanosine (8-OHdG) but increased the serum concentrations of glutathione peroxidase (GSH-Px) in sows on day 1 in lactation. Additionally, sows in the KF group had a lower HOMA insulin resistance value but a higher HOMA insulin sensitivity (HOMA-IS) value. KF induced changes in the gut microbial composition at the phylum and genus levels. The increased relative abundances of Akkermansia and Roseburia in the KF group were positively correlated with the HOMA-IS. Overall, dietary KF alleviated oxidative stress and improved insulin sensitivity of sows, and the changes in the gut microbiota in response to KF may have been correlated with the host metabolism response. IMPORTANCETo date, the effect of dietary fiber on metabolism responses and gut microbiota in sows has not been investigated. Here, KF supplementation of a gestation diet in sows was found to alleviate oxidative stress and to improve insulin sensitivity. Pyrosequencing analysis revealed that KF treatment induces changes in the gut microbiota composition at the phylum and genus levels. Moreover, the changes of gut microbiota in response to KF may be correlated with the host metabolism response.

“…KGM is considered a functional fiber of food ingredient and has been consumed in the form of rubbery jelly, noodles, and other food products by humans in Asia for centuries [16]. KGM has been known to be helpful in lowering cholesterol levels, reducing weight in human beings [17], and modifying intestinal microbial metabolism in sows [18,19]. Our previous study indicated that dietary inclusion of KF with higher water-binding capacity (1.97 vs. 1.78 g/g) and swelling capacity (2.14 vs. 1.62 mL/g) than inclusion of wheat bran promoted the satiety of gestating sow [20].…”

Soluble Fiber with High Water-Binding Capacity, Swelling Capacity, and Fermentability Reduces Food Intake by Promoting Satiety Rather Than Satiation in Rats

To understand whether soluble fiber (SF) with high water-binding capacity (WBC), swelling capacity (SC) and fermentability reduces food intake and whether it does so by promoting satiety or satiation or both, we investigated the effects of different SFs with these properties on the food intake in rats. Thirty-two male Sprague-Dawley rats were randomized to four equal groups and fed the control diet or diet containing 2% konjac flour (KF), pregelatinized waxy maize starch (PWMS) plus guar gum (PG), and PWMS starch plus xanthan gum (PX) for three weeks, with the measured values of SF, WBC, and SC in the four diets following the order of PG > KF > PX > control. Food intake, body weight, meal pattern, behavioral satiety sequence, and short-chain fatty acids (SCFAs) in cecal content were evaluated. KF and PG groups reduced the food intake, mainly due to the decreased feeding behavior and increased satiety, as indicated by decreased meal numbers and increased inter-meal intervals. Additionally, KF and PG groups increased concentrations of acetate acid, propionate acid, and SCFAs in the cecal contents. Our results indicate that SF with high WBC, SC, and fermentability reduces food intake—probably by promoting a feeling of satiety in rats to decrease their feeding behavior.

“…Milk composition and yield are key to the survival and growth of suckling piglets . Furthermore, studies have shown that the improvement of the intestinal health of sows can enhance their lactation ability by improving their appetite and milk quality . Selecting prebiotics and probiotics to improve the intestinal health of sows is an effective measure to improve their reproductive performance.…”

Background In this study, we evaluated the effects of isomaltooligosaccharide (IMO) and Bacillus spp. in perinatal diets on lactational performance, blood metabolites, and milk composition of sows. Multiparous gestating sows (N = 130) with similar body conditions were fed diets without containing IMO (control, CON group), IMO (IMO group), IMO and Bacillus subtilis (IMO + S group), IMO and Bacillus licheniformis (IMO + L group), and IMO and both B. subtilis and B. licheniformis (IMO + S + L group). Results The average daily feed intake of lactating sows in the IMO + S group (P < 0.05) and the average litter gain and total milk yield in the IMO + S + L group (P < 0.01) were significantly higher than those of the sows in the other treatment groups. In addition, the serum alanine aminotransferase and alkaline phosphatase concentrations in all treatment groups were lower than those in the CON group (P < 0.05). Furthermore, the highest proportion of fat in colostrum (0.05 < P < 0.1) and lowest proportion of lactose in milk were observed in the IMO + L group (P < 0.05). The concentrations of growth hormone and immunoglobulins A and G in milk were higher in sows supplemented with IMO, IMO + S, IMO + L, or IMO + S + L (P < 0.05). Conclusion IMO and Bacillus spp. supplementation during the perinatal period improved the sows' lactational performance by affecting their metabolism and milk quality. Sows in the IMO + S and IMO + S + L treatment groups exhibited the best performance. © 2019 Society of Chemical Industry
