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 > 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 < 0.05). From d 15 to 28, ADG of pigs fed the XOS500 diet was higher (P < 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 < 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 < 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 <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.

The effects of dietary chitosan-copper chelate (CS-Cu) on growth performance, diarrhea, intestinal morphology and epithelial cell apoptosis in weaned piglets was investigated. One hundred and sixty Duroc × Landrace × Yorkshire weanling barrows with an average body weight of 7.75 kg were randomly assigned to one of the following dietary treatments: (1) control, (2) 100 mg Cu/kg diet from CuSO<sub>4</sub>, (3) 100 mg Cu/kg diet from CuSO<sub>4</sub> mixed with chitosan (CuSO<sub>4</sub>+CS), (4) 100 mg Cu/kg diet from CS-Cu. The feeding trial lasted for 30 days. The results showed that the pigs receiving a diet containing CS-Cu had higher average daily gain and lower diarrhea incidence than the pigs receiving dietary CuSO<sub>4</sub> and CuSO<sub>4</sub>+CS. Villus height and the ratio of villus height/crypt depth in duodenum, jejunum, and ileum were higher and crypt depth was lower in CS-Cu treated pigs than in pigs fed dietary CuSO<sub>4 </sub>or CuSO<sub>4</sub>+CS. An apparent decrease of ileal epithelial cell apoptosis in pigs fed CS-Cu diet was found. The activities of antioxidant enzymes were higher in pigs fed dietary CS-Cu than in those fed other diets. The results indicated that dietary CS-Cu showed better biological and physiological function in improving small intestinal morphology and reducing diarrhea incidence.

We evaluated whether weaned piglets were protected from bacterial endotoxins by placing the animals on a taurine-supplemented diet. A total of 40 weaned Landrace × Yorkshire piglets (5.75 ± 0.58 kg, weaned at 21 days) were allocated to four groups with 10 barrows per group, following a 2 × 2 factorial design with two inclusion levels of lipopolysaccharide (LPS) (no or one time peritoneal injection by the dose of 100 µg/kg bodyweight on Day 7 of the trial) and two inclusion levels of dietary taurine (no or 0.1% taurine in a basal diet in the whole trial). There was a significant interaction between LPS and taurine with regard to growth and small intestinal mucosal membrane integrity, morphology, immune parameters, and antioxidant capacity (P < 0.05). Feed conversion, daily weight gain, daily feed intake, villus height, and the villus to crypt ratio, vascular endothelial growth factor, regenerating islet-derived protein 3 gamma, trefoil factor-3, transforming growth factor β-1 expression, number of goblet cells and the least amount of claudin-1, occludin, zonula occludens-1, serum glutathione peroxidase, nitrogen oxide synthase, superoxide dismutase, peroxidase, and total antioxidant was lowest in LPS-challenged animals. Furthermore, animals in the LPS group had the highest serum diamine oxidase concentration, number of lymphocytes, concentrations of calprotectin, sIgA, toll-like receptor-4, mRNA levels of interleukin-1β, interleukin-8, toll-like receptor-4, and tumour necrosis factor-α (P < 0.05). These data suggested that the peritoneal injection administration of LPS decreased growth performance and disrupted small intestinal mucosal membrane integrity and triggered an inflammatory response in the small intestinal mucosal membrane. Dietary administration of taurine improved growth performance, increased small intestinal villus height, stimulated immune and antioxidant function and improved small intestinal mucosal membrane integrity in weaned piglets challenged without or with LPS (P < 0.05). The beneficial effects of taurine were likely due to decreased stimulation of the immune response to LPS and an improvement in intestinal epithelial barrier function. Dietary administration of taurine could prevent weaned piglets from intestinal damage by LPS of Gram-negative bacteria.

Tryptophan (Trp) plays an important role in piglet growth. However, the effect of dietary Trp on microbial flora is still poorly understood. A total of 40 28-d weaned piglets were allocated to four groups with 10 barrows per group and one pig per replicate. Piglets were fed a corn and soybean meal-based diet with 0.14%, 0.21%, 0.28%, or 0.35% Trp for four weeks. Five piglets from each diet group were euthanized, and blood and tissue samples were collected. The average daily body weight gain, average daily feed intake, feed conversion ratio, spleen index, pancreas index, longissimus dorsi muscle index, plasma insulin, 5-hydroxytryptamine, kynurenine, and Trp concentrations of weaned piglets increased in a dose-dependent manner (p < 0.05). Compared with the 0.14% Trp diet, the adequate-Trp diets (0.21%, 0.28%, or 0.35%) down-regulated the relative abundances of 12 genera including Turicibacter, Prevotella, Mitsuokella, Anaerovibrio, Megasphaera, Succinivibrio, Sutterella, Desulfovibrio, and Methanobrevibacter (p < 0.05); up-regulated the abundances of Ruminococcaceae, Lactobacillus, and Muribaculaceae in the colon (p < 0.05); and augmented the mRNA level and concentration of porcine β-defensin 2 in the small intestinal mucosa (p < 0.05). Moreover, Trp-adequate diets increased the abundances of Trp hydroxylase, indoleamine 2,3-dioxygenase, porcine β-defensin 2, phosphorylated mammalian target of rapamycin, and phosphorylated protein kinase B in the small intestinal mucosa (p < 0.05). We noted that a corn and soybean meal-based diet with 0.35% Trp may be a nutritional strategy to improve growth performance, intestinal mucosal barrier integrity, and intestinal microbial ecology in weaned piglets.

Sodium butyrate (SB) provided orally favours body growth and maturation of the gastrointestinal tract (GIT) in milk-fed pigs. In weaned pigs, conflicting results have been obtained. Therefore, we hypothesised that the effects of SB (3 g/kg DM intake) depend on the period (before v. after weaning) of its oral administration. From the age of 5 d, thirty-two pigs, blocked in quadruplicates within litters, were assigned to one of four treatments: no SB (control), SB before (for 24 d), or after (for 11–12 d) weaning and SB before and after weaning (for 35–36 d). Growth performance, feed intake and various end-point indices of GIT anatomy and physiology were investigated at slaughter. The pigs supplemented with SB before weaning grew faster after weaning than the controls (P < 0·05). The feed intake was higher in pigs supplemented with SB before or after weaning (P < 0·05). SB provided before weaning improved post-weaning faecal digestibility (P < 0·05) while SB after weaning decreased ileal and faecal digestibilities (P < 0·05). Gastric digesta retention was higher when SB was provided before weaning (P < 0·05). Post-weaning administration of SB decreased the activity of three pancreatic enzymes and five intestinal enzymes (P < 0·05). IL-18 gene expression tended to be lower in the mid-jejunum in SB-supplemented pigs. The small-intestinal mucosa was thinner and jejunal villous height lower in all SB groups (P < 0·05). In conclusion, the pre-weaning SB supplementation was the most efficient to stimulate body growth and feed intake after weaning, by reducing gastric emptying and intestinal mucosa weight and by increasing feed digestibility.

Abstract Benzoic acid (BA) and essential oils (EO) can minimize growth performance losses due to the removal of antibiotics and change the intestinal health of weaned piglets. The objective of this study was to evaluate the effects of BA and EO on inflammatory response, diarrhea incidence, and growth performance of the nursery phase. One hundred and twenty barrows were weaned at 23 days (6.40 ± 0.53 kg) and assigned into 3 treatments (10 replicates) in randomized block design: basal diet without additives (NC), basal diet with 200 ppm of colistin sulphate (PC), and association of 0,3% benzoic acid and essential oil (BA+EO). The feed intake and body weight were recorded at 0 and 42 days. The feces were assessed daily (per animal) and graded as normal feces (no diarrhea) or liquid or pasty stools (presence of diarrhea). On days 1, 3, and 9, blood samples were collected (5 replicates) for white blood cells (WBC) counts. Growth performance was analyzed by MIXED procedure (SAS, 2009) and the Tukey test was used to compare the means (P &lt; 0.050). The WBC counts were analyzed by repeated-measures analysis of variance, by MIXED procedure. Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The BA+EO treatment showed a similar body weight (P = 0.014) and average daily gain (P = 0.012) than the PC group and lower feed conversion ratio (P = 0.037) compared to the NC group. The pigs of the BA+EO treatment had the lowest diarrhea incidence during the total period (P &lt; 0.001). The supplementation with BA+EO or antibiotics reduced the counts of total WBC (P = 0.008) and neutrophils (P = 0.003). In conclusion, supplementation with BA+EO reduces the inflammatory response and the incidence of diarrhea in the nursery phase, that may be related to the improvement in the FCR.
