Abstract The present review summarizes the results of 37 experiments in which different types and levels (from 0.5 to 29.7%) of fibrous supplements were used in the formulation of diets for weaned piglets. Diets were supplemented with different sources of insoluble dietary fiber (iDF), soluble dietary fiber (sDF), or mixed DF sources. Most of the applied DF sources decreased the ileal and fecal organic matter digestibility, and they often lowered crude protein digestibility. A moderate addition (1.5-8%) of iDF sources increased average daily feed intake (ADFI) and, frequently, average daily gains (ADG). Sources of sDF as well as high inclusion levels of fiber-rich feeds tended to decrease ADFI and ADG. Improved fecal consistency, decreased diarrhea incidence and antibiotic interventions were confirmed in piglets fed diets with added lignocellulose, cooked or raw oat hulls and wheat bran. The dietary inclusion of iDF rather than sDF sources improved gastrointestinal tract (GIT) development, enzyme activity and gut morphology. An increase in the counts of beneficial gut microbiota and the concentrations of short-chain fatty acids was stimulated by diets with addition iDF or sDF sources. Such diets also slowed down proteolytic fermentation which negatively affects the colonic mucosa. Some research findings indicate that iDF sources improve intestinal barrier function. The analyzed experimental data suggest that the addition of 1.5-2% of a lignocellulose preparation, 2% of oat hulls, 4-8% of coarse wheat bran to diets for weaned piglets may be recommended to promote GIT development and health, and to improve growth performance.

Abstract Background: The effects of dietary supplementation with guava leaf extracts (GE) on growth performance, diarrhea and intestinal barrier function, as well as associated with its modulation of serum and fecal metabolic changes in weaned piglets challenged by enterotoxigenic Escherichia coli (ETEC) were investigated.Method: Fifty weaned piglets (Duroc × Yorkshire × Landrace) from 5 pens (2 piglets per pen) were randomly divided into five groups: blank control group (BC), negative control group (NC), or those supplemented with 50 mg kg-1 (S50), 100 mg kg-1 (S100), or 200 (S200) mg kg-1 diet GE, respectively. On day 4, all piglets (except for BC) were orally challenged with about 1.0 × 109 colony-forming units (CFU) enterotoxigenic ETEC. After 28-day trial, growth performance, diarrhea incidence, intestinal barrier function and metabolomics of serum and fecal were investigated.Results: We demonstrated that dietary supplementation with GE (50-200 mg kg-1) reduced diarrhea incidence of piglets and increased expression of intestinal tight junction proteins (ZO-1, Occludin, Claudin-1) (P < 0.05) and sodium hydrogen exchanger 3 (NHE3) (P < 0.05). Moreover, dietary supplementation with GE (50-200 mg kg-1) upregulated level of tetrahydrofolic acid (THF) and reversed higher level of nicotinamide-adenine dinucleotide phosphate (NADP) caused by ETEC in serum compared with NC group (P < 0.05), and enhanced antioxidant ability of piglets. In addition, dietary addition with GE (100 mg kg-1) reversed the lower level of L-pipecolic acid caused by ETEC in feces compared with NC group (P < 0.05), and decreased oxidative stress response of piglets. Further, there were no differences (P > 0.05) in the final weight, average daily feed intake (ADFI) and F/G among dietary groups during the overall period, and piglets in S50 group has the higher average daily gain (ADG). Conclusion: Dietary supplementation with 50-200 mg kg-1 GE reduced diarrhea incidence of weaned piglets challenged by ETEC and exhibited positive effect on improving intestinal barrier function. Meanwhile, dietary addition with GE organized and redistributed energy resources through similar or dissimilar metabolic pathways, and finally enhanced antioxidant ability of piglets challenged by ETEC.

Insoluble Fiber

The main purpose of the present study was to assess the effect of soluble and insoluble fiber on colonic bacteria and intestinal barrier function in a piglet model. A total of 24 piglets (25 ± 1 d old; 7.50 ± 0.31 kg) were randomly allotted to 4 treatments: basal diet (control, CON), 1% insoluble dietary fiber (IDF) diet, 1% soluble dietary fiber (SDF) diet, and 0.5% insoluble fiber + 0.5% soluble dietary fiber (MDF) diet. The trial lasted 28 days. SDF-fed piglets showed a higher P<0.05 bacterial a-diversity (observed_species, chao1, and ACE) and a higher relative abundance of Proteobacteria and Actinobacteria, Solobacterium, Succinivibrio, Blautia, and Atopobium in colonic digesta than CON, IDF, and MDF groups P<0.05. At the same time, Bacteroidetes, Euryarchaeota, Phascolarctobacterium, Coprococcus_1, and Prevotella_1 were significantly increased in the IDF group when compared with CON, SDF, and MDF groups P<0.05. Furthermore, Bacteroidetes and Enterobacteriaceae, Selenomonas, Phascolarctobacterium, and AlloprevotellaP<0.05 were significantly higher in the MDF group than those in the other three groups P<0.05. SDF diet increased the concentrations of short-chain fatty acid (SCFA) in colonic digesta P<0.05 when compared with the CON group and enhanced weight index of the colon P<0.05 than the CON and IDF groups. Furthermore, compared with the CON group, SDF, IDF, and MDF diets all upregulated the mRNA expressions of claudin-1 (CLDN-1) in colonic mucosa P<0.05, SDF and IDF diets upregulated the mRNA expressions of mucin 2 (MUC2) P<0.05, SDF diet increased mRNA expressions of zonula occludens 1 (ZO-1) and occludin (OCLN), while the IDF group enhanced the secretory immunoglobulin A (sIgA) concentrations P<0.05, respectively. IDF and MDF diets decreased expressions of TNF-αP<0.05. We concluded that the influence of soluble fiber on colonic microbiota was more extensive than that of insoluble fiber. Moreover, soluble fiber could more effectively improve colonic barrier function by upregulating gene expressions of the gut barrier.

This study investigated the effects of dietary C. butyricum ZJU-F1 on the apparent digestibility of nutrients, intestinal barrier function, immune response, and microflora of weaned piglets, with the aim of providing a theoretical basis for the application of Clostridium butyricum as an alternative to antibiotics in weaned piglets. A total of 120 weanling piglets were randomly divided into four treatment groups, in which piglets were fed a basal diet supplemented with antibiotics (CON), Bacillus licheniformis (BL), Clostridium butyricum ZJU-F1 (CB), or Clostridium butyricum and Bacillus licheniformis (CB-BL), respectively. The results showed that CB and CB-BL treatment increased the intestinal digestibility of nutrients, decreased intestinal permeability, and increased intestinal tight junction protein and mucin expression, thus maintaining the integrity of the intestinal epithelial barrier. CB and CB-BL, as exogenous probiotics, were also found to stimulate the immune response of weaned piglets and improve the expression of antimicrobial peptides in the ileum. In addition, dietary CB and CB-BL increased the proportion of Lactobacillus. The levels of butyric acid, propionic acid, acetic acid, and total acid were significantly increased in the ceca of piglets fed CB and CB-BL. Furthermore, we validated the effects of C. butyricum ZJU-F1 on the intestinal barrier function and immune response in vitro and found C. butyricum ZJU-F1 improved intestinal function and enhanced the TLR-2-MyD88-NF-κB signaling.

Abstract BACKGROUND: The beneficial function of fermented feed in livestock industry has been widely investigated. However, little is known about the effects of fermented feed on different weaned-day piglets. This study aimed to investigate the effects of fermented diet on the growth performance, intestinal function and microbiota of piglets weaned at age of 21 days and 28 days.RESULTS: The results found that weaning on d 21 significantly increased (P < 0.05) ADG, and ADFI (calculated based on wet weight and dry matter), while reduced (P < 0.05) F: G, the activities of trypsin and lipase of jejunum and villus height of ileum, compared with 28-d weaning. The protein levels of Occludin, Claudin-1, ZO-1 of ileum in the groups weaning on d 21 were less (P < 0.05) than the groups weaning on d 28. Moreover, dietary supplementation with fermented diet upregulated (P < 0.05) Occludin, Claudin-1, ZO-1 proteins of ileum, compared with the groups treated with control diet both weaning on d 21 and d 28. In addition, dietary supplementation with fermented diet decreased (P < 0.05) the relative abundance of Clostridia (class) and increased (P < 0.05) Bacteroidia (class) level of cecal microbiota, compared with the groups treated with control diet both weaning on d 21 and d 28. However, supplementation with fermented diet did not affect the concentrations of short-chain fatty acids in the cecum (P > 0.05).CONCLUSION: Therefore, our data suggest that feed digestibility is improved in piglets weaned at 21 days, but intestinal barrier function is weaker than in piglets weaned at 28 days. However, compared with feeding control diet, supplementation with fermented diet both improved feed conversion and intestinal barrier function of weaned piglets by modulating intestinal microbiota.

Abstract The objective of this study was to investigate the effects of xylo-oligosaccharides (XOS) supplementation on growth performance, serum parameters, small intestinal morphology, intestinal mucosal integrity, and immune function in weaned piglets. A total of 240 weaned piglets with an average body weight (BW) of 8.82 ± 0.05 kg (28 d of age) were assigned randomly to 4 dietary treatments in a 28-d trial, including a control diet (CON), 3 diets with XOS supplementation at the concentration of 100, 500 and 1000 mg/kg (XOS100, XOS500, and XOS1000). There were 4 replicates per treatment with 15 pigs per pen. From d 1 to 14, there were no differences (P &gt; 0.05) in average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G:F) during the different treatments. The different doses of XOS showed a quadratic effect on BW on d 28, ADG and G:F d 1-28 of piglets (P &lt; 0.05). From d 15 to 28, ADG of pigs fed the XOS500 diet was higher (P &lt; 0.05) than pigs fed the CON diet. During the overall period (d 1 to 28), pigs fed the XOS500 diet had a higher BW, ADG and G:F than pigs fed the CON diet (P &lt; 0.05). In addition, compared with the CON group, the XOS500 group had significantly higher serum total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD) and catalase (CAT) levels and lower malondialdehyde (MDA) levels on d 14 and 28 (P &lt; 0.05). The serum immunoglobulin G (IgG) concentration in the XOS500 group was also significantly higher compared with the CON group on d 14 and 28 (P &lt;0.05). However, serum immunoglobulin A (IgA) and immunoglobulin M (IgM) were not affected by the dietary treatments. Supplementation of XOS500 to the feed significantly increased the villus height (VH) and villus height to crypt depth ratio (VH:CD) in the jejunum and ileum in comparison with the CON and XOS1000 group. Moreover, the XOS500 group significantly elevated the expression levels of Occludin and zonula occludens protein-1 (ZO-1) in the ileum compared to the CON group. The ileal interleukin (IL)-1β, IL-8 and interferon (IFN)-γ mRNA expression levels in the XOS100 and XOS500 group were markedly lower than in the CON group. In contrast, the ileal IL-10 mRNA expression levels were remarkably higher in the XOS500 than CON group. In conclusion, xylo-oligosaccharides have a beneficial effect on growth performance by improving serum antioxidant defense system, serum IgG, small intestinal structure and intestinal barrier function in weaned piglets.

Intestinal Barrier Function

Postoperative infectious complication (POIC) is one of the most common complications following highly invasive abdominal surgeries, such as hepatectomy, esophagectomy, and pancreatoduodenectomy. The surgical stress temporarily deteriorates the intestinal microenvironment, and the fecal concentrations of beneficial bacteria such as Bifidobacterium and Lactobacillus decrease following highly invasive abdominal surgery. In parallel with these changes, the concentrations of fecal short-chain fatty acids (SCFAs) such as acetic acid, propionic acid, and butyric acid also decrease after surgery. In contrast, the fecal concentration of lactic acid increases under this condition because of the deterioration of the metabolism from lactic acid to SCFAs by normal intestinal microflora. Decreased fecal concentration of SCFAs may lead to an impaired intestinal barrier function under stressful condition. Translocation of bacteria from the gut to lymphatic and bloodstream leads to bacteremia and subsequent POICs. The incidence of POICs in patients with unhealthy intestinal microflora before surgery may be more because their intestine is more susceptible to bacterial translocation induced by surgical stress. Therefore, improving the intestinal microenvironment and intestinal barrier function before surgery is crucial to prevent POICs following highly invasive abdominal surgeries. In this regard, the use preoperative synbiotics therapy may be one of the effective ways because it has been shown to improve intestinal microflora, increase fecal SCFAs, prevent bacterial translocation, and reduce the incidence of POICs in several randomized controlled trial in patients undergoing highly invasive abdominal surgeries.

Abstract Background Research on intestinal microbiota has grown considerably, as well as the interest on probiotics’ supplementation effects on metabolism. Considering high prevalence rates of metabolic diseases linked by insulin resistance, we performed a systematic review of existing literature which addressed the role of probiotics in modulating insulin sensitivity in animals and humans. Methods This systematic review was based on PRISMA guidelines. Searches for original articles published in English from 1990 to January 2020 were made in the electronic database of PubMed from the National Library of Medicine, using Medical Subject Headings to identify longitudinal studies conducted in animals and humans which reported effects of probiotics in a variety of insulin resistance parameters. Results Overall, results from 27 probiotic interventions (Lactobacillus, Bifidobacterium, Clostridium and Akkermansia) indicated significant beneficial changes in insulin resistance measures in animal studies. Additionally, they improved lipid profile, inflammatory and oxidative markers, short-chain fatty acids production and microbiota composition. In seven clinical trials, samples and designs were heterogeneous. Five showed benefits in insulin resistance parameters and in two others no effect was detected. Conclusion Available data regarding the effects of certain probiotics do not guarantee sustained amelioration of insulin resistance in humans. Consistent beneficial results for intestinal barrier function, immune system and metabolism were reported in animals may encourage long-term randomized clinical trials in people with obesity and cardiometabolic risk. Whether supplementation with probiotics in combination with medications and/or prebiotics, associated with a healthy lifestyle, will prove useful to attenuate insulin resistance requires further investigation.
