Abstract To evaluate the effects of probiotics on performance and gut health of Escherichia coli-challenged weaned pigs, a total of 28 weaned pigs (initial BW = 8.25 kg) were housed individually in pens and fed 4 experimental diets for 21 d in a completely randomized design. The 4 diets were corn-soybean meal-based basal diet without or with 0.25% antibiotics (neomycin + oxytetracycline), 0.05% Bacillus subtilis DSM 32540, or 0.05% Bacillus pumilus DSM 32539. All pigs were orally challenged with K88 strain of E. coli on d 3. Feed intake and BW data, and blood samples were collected on d 3, 7, 14, and 21. Fecal scores were recorded daily. On d 21, pigs were sacrificed to determine gastrointestinal histomorphology, pH and organ weights. Supplementation of the basal diet with antibiotics or B. pumilus did not affect the overall (d 0 to 21) ADG and G:F. The B. subtilis supplementation did not affect the overall ADG, but tended to increase (P < 0.1) the overall G:F by 15%. Fecal score was unaffected by dietary treatment. Supplementation of the basal diet with either probiotic, but not antibiotics increased (P < 0.05) jejunal villous height and reduced (P < 0.05) cecal digesta pH. Supplementation with B. pumilus tended to increase (P < 0.1) colon weight relative to BW; however, antibiotics or B. subtilis supplementation did not affect colon weight. The addition of B. subtilis to basal diet tended to increase (P < 0.1) serum immunoglobulin A concentration on d 21 of the study; however, such effect was not observed with the addition of antibiotics or B. pumilus. In conclusion, dietary B. subtilis improved G:F and jejunal villous height and reduced cecal digesta pH, indicating that dietary supplementation with B. subtilis at 0.05% could improve growth performance and gut health of weaned pigs.

Abstract This study was conducted to investigate the effects of a direct-fed microbial (DFM) product (Bacillus subtilis strain DSM 32540) in weaned pigs challenged with K88 strain of Escherichia coli on growth performance and indicators of gut health. A total of 21 weaned pigs [initial body weight (BW) = 8.19 kg] were housed individually in pens and fed three diets (seven replicates per diet) for 21 d in a completely randomized design. The three diets were a corn-soybean meal-based basal diet without feed additives, a basal diet with 0.25% antibiotics (neo-Oxy 10-10; neomycin + oxytetracycline), or a basal diet with 0.05% DFM. All pigs were orally challenged with a subclinical dose (6.7 × 108 CFU/mL) of K88 strain of E. coli on day 3 of the study (3 d after weaning). Feed intake and BW data were collected on days 0, 3, 7, 14, and 21. Fecal scores were recorded daily. On day 21, pigs were sacrificed to determine various indicators of gut health. Supplementation of the basal diet with antibiotics or DFM did not affect the overall (days 0–21) growth performance of pigs. However, antibiotics or DFM supplementation increased (P = 0.010) gain:feed (G:F) of pigs during the post-E. coli challenge period (days 3–21) by 23% and 24%, respectively. The G:F for the DFM-supplemented diet did not differ from that for the antibiotics-supplemented diet. The frequency of diarrhea for pigs fed a diet with antibiotics or DFM tended to be lower (P = 0.071) than that of pigs fed the basal diet. The jejunal villous height (VH) and the VH to crypt depth ratio (VH:CD) were increased (P < 0.001) by 33% and 35%, respectively, due to the inclusion of antibiotics in the basal diet and by 43% and 41%, respectively due to the inclusion of DFM in the basal diet. The VH and VH:CD for the DFM-supplemented diet were greater (P < 0.05) than those for the antibiotics-supplemented diet. Ileal VH was increased (P < 0.05) by 46% due to the inclusion of DFM in the basal diet. The empty weight of small intestine, cecum, or colon relative to live BW was unaffected by dietary antibiotics or DFM supplementation. In conclusion, the addition of DFM to the basal diet improved the feed efficiency of E. coli-challenged weaned pigs to a value similar to that of the antibiotics-supplemented diet and increased jejunal VH and VH:CD ratio to values greater than those for the antibiotics-supplemented diet. Thus, under E. coli challenge, the test DFM product may replace the use of antibiotics as a growth promoter in diets for weaned pigs to improve feed efficiency and gut integrity.

Abstract The objective of this experiment was to investigate dietary supplementation of oligosaccharide-based polymer on growth performance, diarrhea, and fecal β-hemolytic coliforms of weaned pigs experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Forty-eight pigs (7.23 ± 1.11 kg BW) were individually housed in disease containment rooms and randomly allotted to one of four treatments with 12 replicate pigs per treatment. The four dietary treatments were a nursery basal diet (control), and 3 additional diets supplemented with 50 mg/kg Mecadox (AGP), 10 or 20 mg/kg of oligosaccharide-based polymer. The experiment lasted 18 d [7 d before and 11 d after the first inoculation (d 0)]. The doses of F18 E. coli inoculum were 1010 cfu/3 mL oral dose daily for 3 days. Growth performance was measured on d -7 to 0 before inoculation, and d 0 to 5 and 5 to 11 post-inoculation (PI). Diarrhea score (DS; 1, normal, to 5, watery diarrhea) was daily recorded for each pig. Fecal samples were collected on d 2, 5, 8, and 11 PI to test the percentage of β-hemolytic coliforms in total coliforms. All data were analyzed by ANOVA using the PROC MIXED of SAS with pig as the experimental unit. Inclusion of oligosaccharide-based polymer linearly increased (P < 0.05) ADFI on d 0 to 5 PI, and feed efficiency on d 0 to 5 PI and d 5 to 11 PI (P = 0.07), compared with the control. Supplementation of AGP or oligosaccharide-based polymer reduced (P < 0.01) frequency of diarrhea of pigs from d 0 to 11 PI. No differences were observed in overall growth performance and percentage of fecal β-hemolytic coliforms on d 8 PI among pigs in AGP and oligosaccharide-based polymer treatments. In conclusion, supplementation of oligosaccharide-based polymer enhanced feed efficiency and reduced diarrhea of weaned pigs infected with a pathogenic E. coli.

Abstract Background: Probiotics seem to be an alternative to antibiotics for improving animal's health and intestinal development. Saccharomyces boulardii ( S. boulardii ) is a well-known probiotic. However, only few studies have been performed examining the effects of S. boulardii on weaned piglets . Therefore, this study was conducted to investigate the effects of dietary S. boulardii mafic-1701 on growth performance, antioxidant parameters, inflammation and intestinal microbiota in weaned piglets, using aureomycin as positive control. One hundred and eight piglets were randomly divided into three dietary treatment groups: (1) basal diet (CON); (2) basal diet supplemented with 75 mg/kg aureomycin (ANT); (3) basal diet supplemented with 1 × 10 8 CFU/kg S. boulardii mafic-1701 (SB). Results: Compared to CON, the supplementation with S. boulardii mafic-1701 improved feed efficiency over the entire 28 days ( P < 0.01) and decreased the rate of diarrhea during the first week ( P < 0.05). Total superoxide dismutase concentration was markedly increased in piglets with S. boulardii mafic-1701 ( P < 0.01). Moreover, compared with CON, SB increased the concentration of interleukin-4 in ileum ( P < 0.05), while the level of pro-inflammatory cytokines interleukin-6 ( P < 0.01) and tumor necrosis factor ( P < 0.01) were decreased in jejunum. SB increased the abundance of Bacillus and Ruminococcaceae ( P < 0.05), whereas the population of Clostridiaceae were decreased ( P < 0.05). Furthermore, the analysis of microbiota metabolites showed that S. boulardii mafic-1701 administration increased the concentration of formate and isobutyrate in cecum to maintain a stable microbiota and gut health ( P < 0.05). Conclusion: This study indicated that S. boulardii mafic-1701 supplementation could improve growth performance, alleviate the severity of diarrhea in weaned piglets, which may be associated with S. boulardii mafic-1701 promoted antioxidant activity, anti-inflammatory responses and microbi al ecology of piglets.

Feeding fermentable carbohydrates (FC) to weanling pigs may reduce the negative impact of proteolytic fermentation on gastrointestinal health and function. A total of 144 newly weaned pigs [6.23 kg body weight (BW); six pens per treatment; six pigs per pen) were used to determine the interactive effects of feeding additional fermentable protein (FP) and FC on growth performance, gastrointestinal function and intestinal health. Dietary treatments, based on a 2 × 2 factorial arrangement, were: (1) basal diet (control); (2) control + 10% poultry meal (PM) as FP source; (3) control + 5% beet pulp (BP) as FC source; and (4) control + 10% PM and 5% BP. Diets were formulated to be similar in digestible energy (DE) and digestible amino acid contents. In general, no interactive effects of FC and FP were observed (P > 0.10). During the 3-wk post-weaning period, feeding FP reduced average daily gain (ADG) (242 vs. 269 g d-1; P < 0.05), while FC increased ADG (269 vs. 243 g d-1; P < 0.05). Overall, feed intake did not differ between treatments (P > 0.10). On days 14 and 28 post-weaning, Clostridia spp. counts in colon contents, counts of white cells and segmented neutrophils in blood were lowered (P < 0.05) by feeding FC. Blood urea nitrogen was increased by feeding FP (9.5 vs. 6.5 mg dL-1; P < 0.05), while ammonia concentration in colon contents was lowered by FC (154 vs. 193 µg mL-1) (P = 0.06). Among biogenic amines, levels of tyramine (140 vs. 304 nmol g-1 DM) and spermidine (174 vs. 219 nmol g-1 DM) in colon contents were lowered (P < 0.05) by FC. Acetic, proprionic and butyric acid contents in colon contents were increased by feeding FC, while valeric and caproic acid content decreased by feeding FP (P < 0.05). Feeding FC and FP had no effect (P > 0.10) on colon histology, pH, fecal consistency score and organ weights. Results suggest that FP and FC have independent effects on newly weaned pigs, while effects appear partly related to changes in gut microbiota.

Abstract The experiment was conducted to investigate the effects of trace amounts of antibiotic on growth performance, diarrhea, systemic immunity, and intestinal health of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli. Weaned pigs (n = 34, 6.88 ± 1.03 kg body weight [BW]) were individually housed in disease containment rooms and randomly allotted to one of the three dietary treatments: nursery basal diet (CON) and two additional diets supplemented with 0.5 or 50 mg/kg carbadox to the nursery basal diet (TRA or REC), respectively. The experiment lasted 18 d with 7 d before and 11 d after the first E. coli inoculation. The E. coli F18 inoculum was orally provided to all pigs with a dose of 1010 colony-forming unit (CFU)/3 mL for three consecutive days. Fecal and blood samples were collected on day 0 before inoculation and days 2, 5, 8, and 11 postinoculation (PI) to test the percentage of β-hemolytic coliforms in total coliforms and complete blood cell count, respectively. Sixteen pigs were euthanized on day 5 PI, whereas the remaining pigs were euthanized at the end of the experiment to collect the jejunal and ileal mucosa and mesenteric lymph node for gene expression and bacterial translocation, respectively. Pigs in REC had greater (P &lt; 0.05) final BW and lower (P &lt; 0.05) overall frequency of diarrhea compared with pigs in the CON and TRA groups. Pigs in TRA had the lowest (P &lt; 0.05) average daily gain and feed efficiency from day 0 to 5 PI, highest (P &lt; 0.05) percentage of β-hemolytic coliforms in fecal samples on days 2 and 5 PI, and greatest (P &lt; 0.05) bacterial colonies in mesenteric lymph nodes on day 11 PI compared with pigs in the CON and REC groups. Pigs in TRA had the greatest (P &lt; 0.05) neutrophils on day 5 PI and higher (P &lt; 0.05) white blood cell counts and lymphocytes than other groups on day 11 PI. Pigs in TRA had the greatest (P &lt; 0.05) serum C-reactive protein on days 2 and 5 PI and serum tumor necrosis factor-α on day 5 PI, compared with pigs in the CON and REC groups. Pigs fed REC had increased (P &lt; 0.05) mRNA expression of zona occludens-1 (ZO-1) and occludin (OCDN) and reduced (P &lt; 0.05) interleukin-1 beta (IL1B), interleukin-6 (IL6), and tumor necrosis factor-alpha (TNFA) in ileal mucosa on day 5 PI, compared with the CON, whereas TRA upregulated (P &lt; 0.05) mRNA expression of IL1B, IL6, and cyclooxygenase-2 (COX2) in the ileal mucosa on day 11 PI, compared with the REC. In conclusion, trace amounts of antibiotic may exacerbate the detrimental effects of E. coli infection on pig performance by increasing diarrhea and systemic inflammation of weanling pigs.

Abstract This study was to investigate the effect of dietary supplementation with xylanase and probiotic on growth performance, and gut health of nursery pigs challenged with ETEC. Sixty-four weaned pigs (7.9 ± 0.4 kg) were allotted in a RCBD (2 x 2 factorial). ETEC (0, and ETEC, 6 x 109 CFU/mL) and synbiotic (0, and xylanase 10,000 XU/kg combined with Bacillus sp. 6 x 108 CFU/kg) were the factors. ETEC was orally inoculated on d 7. Growth performance were measured on d 7, 10, 15, and 21. On d 21, 48 pigs were euthanized for sampling to measure gut health parameters. Synbiotic increased (P &lt; 0.05) ADG in P1 (53.5 to 96.0 g). Overall, ETEC reduced (P &lt; 0.05) ADG (387.5 to 322.5 g) and G:F (0.810 to 0.706). ETEC increased (P &lt; 0.05) fecal score from d 7 to 13, whereas synbiotic reduced (P &lt; 0.05) it at d 9 and 11 in challenged pigs. ETEC increased (P &lt; 0.05) MDA (0.259 to 0.818 μmol/mg), IL6 (2.96 to 4.30 pg/mg), ki-67+ (29.1 to 33.9%), and crypt depth (260 to 290 μm), whereas synbiotic tended to reduce TNF-α (1.05 to 0.87 pg/mg), protein carbonyl (3.13 to 2.51 nmol/mg), and IL6 (4.07 to 3.19 pg/mg); reduced (P &lt; 0.05) crypt depth (290 to 260 μm), and ki-67+ (32.7 to 30.3%) and increased (P &lt; 0.05) villus height (368.5 to 421.4 μm). ETEC reduced (P &lt; 0.05) abundance of Veillonellaceae (7.11 to 3.02%), tended to reduce (P = 0.067) Clostridiaceae (1.1 to 0.55%), and Prevotellaceae (38.0 to 27.2%) and tended (P = 0.063) to increase Helicobacteraceae (34.5 to 49.5%). Collectively, ETEC reduced growth performance by affecting the microbiome, oxidative stress, and immune response. Synbiotic improve growth performance by enhancing gut health regardless of the challenge, whereas it reduced fecal score in challenged pigs.

Abstract The study was conducted to investigate the efficacy of a probiotic Bacillus subtilis strain on growth performance, diarrhea, systemic immunity, and intestinal health of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli and to compare the efficacy of B. subtilis with that of carbadox. Weaned pigs (n = 48, 6.17 ± 0.36 kg body weight [BW]) were individually housed in disease containment rooms and randomly allotted to one of four dietary treatments: negative control (NC, control diet without E. coli challenge), positive control (PC, control diet with E. coli challenge), and supplementation of 50 mg/kg of carbadox (antibiotic growth promotor [AGP]) or 2.56 × 109 CFU/kg of B. subtilis probiotics (PRO). The experiment lasted for 28 d with 7 d before and 21 d after the first E. coli inoculation. Fecal and blood samples were collected on days 0, 3, 7, 14, and 21 post inoculation (PI) to analyze β-hemolytic coliforms and complete blood cell count, respectively. Diarrhea score was recorded daily for each pig to calculate the frequency of diarrhea. All pigs were euthanized at day 21 PI to collect jejunal and ileal mucosa for gene expression analysis. Pigs in AGP had greater (P &lt; 0.05) BW on days 7, 14, and 21 PI than pigs in PC and PRO groups. Supplementation of PRO enhanced pigs’ BW on day 21 PI compared with the PC. Escherichia coli F18 challenge reduced (P &lt; 0.05) average daily gain (ADG) and feed efficiency from day 0 to 21 PI, while supplementation of carbadox or PRO enhanced ADG and feed efficiency in E. coli F18-challenged pigs from day 0 to 21 PI. Pigs in AGP and PRO groups had reduced (P &lt; 0.05) frequency of diarrhea throughout the experiment and fecal β-hemolytic coliforms on day 7 PI than pigs in the PC. Pigs in PRO had greater (P &lt; 0.05) gene expression of CLDN1 in jejunal mucosa than pigs in the PC. Supplementation of carbadox or PRO reduced (P &lt; 0.05) the gene expression of IL6 and PTGS2 in ileal mucosa of E. coli-infected pigs compared with pigs in the PC. Pigs in the PRO group had lower (P &lt; 0.05) white blood cell number and neutrophil count, and serum haptoglobin concentration on day 7 PI, and less (P &lt; 0.05) monocyte count on day 14 PI, compared with PC. In conclusion, supplementation of probiotic B. subtilis could enhance disease resistance and promote the growth performance of weaned pigs under disease challenge conditions. The potential mechanisms include but not limited to enhanced gut barrier integrity and local and systemic immune responses of weaned pigs.

Abstract The objective was to test the efficacy of L-Thr or L-Val with biomass (ThrPro or ValPro; CJ BIO, Fort Dodge, IA) on growth performance and health compared with L-Thr or L-Val (purified) in newly-weaned pigs. There were 9 dietary treatments based on NRC (2012) requirements: NC (basal diet meeting 70% of requirements for SID Thr and Val); 4 treatments based on basal diet meeting 95% of requirements: LT (with L-Thr), LV (with L-Val), PT (with ThrPro), and PV (with ValPro); HLT (fivefold L-Thr in LT), HLV (fivefold L-Val in LV), HPT (fivefold ThrPro in PT), and HPV (fivefold ValPro in PV). Pigs were fed for 26 d in 2 phases. Feed intake and BW were measured at d 0, 5, 10, 17, and 26. Blood was collected on d 21 for liver function analysis. Pigs were euthanized on d 26 to collect jejunal mucosa for gut health parameters. Data were analyzed by SAS using MIXED procedure. Pigs fed LT and LV or PT and PV had higher (P &lt; 0.05) ADG than pigs fed NC during phase 2. Pigs fed LT, LV, PT, and PV had higher ADFI and G:F than pigs fed NC during d 17 to 26. Pigs fed PT and PV had lower (P &lt; 0.05) G:F than pigs fed HPT and HPV during phase 2. Pigs fed LT and LV or PT and PV had lower (P &lt; 0.05) BUN than pigs fed NC. Overall, pigs fed PT and PV had no differences in any analyzed measurements from pigs fed LT and LV and pigs fed HPT and HPV. In conclusion, PT and PV were equally efficient to LT and LV for growth performance and health. HPT and HPV did not impair liver and gut health compared with PT and PV.

Abstract An experiment was conducted to evaluate the effects of including canola meal (CM) in diets for weaning pigs challenged with a F18 strain of E. coli on growth performance and gut health. A total of 36 individually housed weaned pigs [initial body weight (BW) = 6.22 kg] were randomly allotted to 1 of the 3 diets (12 pigs/diets). The 3 diets were corn-soybean meal (SBM)-based basal diet (control diet) and the basal diet with 0.3% zinc oxide, 0.2% chlortetracycline, and 0.2% tiamulin (antibiotic diet), or with 20% canola meal (CM diet). The diets were fed in 2 phases; Phase 1: d 0 to 7, and Phase 2: d 7 to 20. All pigs were given an oral dose of 2 × 10 9 CFU of F18 strain of E. coli on d 7. Fecal score was assessed daily throughout the trial. Dietary antibiotics increased (P &lt; 0.05) overall ADG and ADFI compared by 48% and 47%, respectively. Dietary CM increased (P &lt; 0.05) overall ADG and ADFI by 22% and 23%, respectively; but the ADG and ADFI values for CM-containing diet did not reach those for the antibiotics-containing diet. Dietary antibiotics reduced (P &lt; 0.05) fecal score; however, dietary CM unaffected fecal score. Dietary antibiotics decreased (P &lt; 0.05) liver weight per unit live BW by 16% at d 20; whereas dietary CM did not affect liver weight per unit live BW (29.2 vs. 28.6). Also, dietary antibiotics increased (P &lt; 0.05) serum triiodothyronine and tetraiodothyronine levels for d 14; whereas dietary CM did not affect the serum level of these hormones. Dietary antibiotics reduced (P &lt; 0.05) the number white blood cells and neutrophils by 38% and 43% at d 20, respectively; whereas dietary CM tended to reduce (P = 0.09) the number white blood cells by 19% at d 20. The number white blood cells for CM diet tended to be greater (P &lt; 0.10) than that for antibiotics diet. The dietary antibiotics decreased (P &lt; 0.05) the concentration of individual volatile fatty acids and hence of total volatile fatty acid in cecum by 61% at d 20; whereas dietary CM decreased (P &lt; 0.05) cecal butyric acid concentration by 61% and tended to reduce (P &lt; 0.10) total volatile fatty acid concentration by 30% at d 20. In conclusion, the dietary inclusion of 20% canola meal improved ADG and tended to reduce white blood cell counts. Thus, inclusion of CM in antibiotics-free corn-SBM-based diets for weaned pigs that are challenged with F18 strain of E. coli can result in their improved performance partly through a reduction of the inflammatory response.

The research aims to study the use of synbiotics as feed additives in rations on describe lesions histopathology and population of lactic acid bacteria in duodenum infected with Escherichia coli. The study used 96 broiler Jumbo series A Cibadak strains which were maintained until the age of six weeks. The study was conducted by experimental method, using a completely randomized design (CRD) with eight treatments of rations and four replications. The broilers were devided into eight treatment diets: R1 (basal diet/control), R2 (basal diet + prebiotic 0.4%); R3 (basal diet + probiotic 108 CFU); R4 (basal diet + prebiotic 0.4% + probiotic 108 CFU); R5 (basal diet + infected with E. coli 104 CFU); R6 (basal diet + prebiotic 0.4% + infected with E. coli 104 CFU); R7 (basal diet + probiotic 108 CFU + infected with E. coli 104 CFU); and R8 (basal diet + prebiotic 0.4% + probiotic 108 CFU + infected with E. coli 104 CFU). The observed variables were histopathology based on lesio microscopic and lactic acid bacteria population in duodenum age 2, 4 and 6 weeks. Data was analyzed by using one-way analysis of variance then continued with Duncan test. The results showed that the use of probiotics, prebiotics and synbiotics significantly (P<0.05) decreased histopathological lesio score and increased the population of lactic acid bacteria in duodenum age 2, 4 and 6 weeks. In conclusion the use of synbiotics as feed additives in the ration a positive on describe lesions histopathological and increase in the population of lactic acid bacteria in duodenum age 2, 4 and 6 weeks infected and not infected with E. coli.
