Lactobacillus Mucosae

Abstract Addition of pre- and probiotics may confer growth and health benefits when added to the diet of pigs. To determine the effects of feeding mannan oligosaccharide (MOS) and Lactobacillus mucosae (LM) as prebiotic and probiotic sources in weanling pigs under immune challenge, 96 weaned pigs were randomly allotted to 16 experimental pens within a 2 × 2 factorial arrangement of treatments. Control diets with or without 0.1% yeast-derived MOS were randomly assigned to pens and 109 cfu/pig LM broth or a control broth were top-dressed daily. Pigs were fed one of four dietary treatments (control, MOS, LM, and MOS+LM) in Phases I and II (days 0 to 7 and days 7 to 21 postweaning, respectively) and a common diet during Phase III (days 21 to 35 postweaning). On day 14, all pigs were challenged with 100 µg/kg body weight (BW) Escherichia coli lipopolysaccharide (LPS) via intraperitonial injection. Feed disappearance and pig BW were measured weekly. Blood and fecal samples were collected weekly, and additional blood samples were collected on days 1 and 3 post-LPS challenge. On days 15 and 21, one pig per pen was euthanized for collection of ileal mucosa and duodenal and ileal tissue samples. From days 0 to 14, feeding LM decreased gain-to-feed ratio (G:F; P < 0.05). An interaction between LM and MOS was observed for G:F on days 14 to 21 (P < 0.05); G:F in LM (715 g/kg) was greater compared with MOS+LM (P < 0.05; 600 g/kg) and control (P < 0.10; 615 g/kg), but was not different (P > 0.10) from MOS (674 g/kg). After pigs were fed a common diet (days 21 to 35), G:F was decreased (P < 0.05) in the LM treatment groups. Pigs fed diets that included MOS had increased serum immunoglobulin (Ig) G on days 1 and 3 post-LPS challenge and 2 wk after removal of treatments (P < 0.05) and on days 14 and 21 postweaning (P < 0.10) compared with pigs fed diets without MOS. On day 15, mucosal immunoglobulin G was increased (P < 0.05) in control vs. MOS and LM groups. Circulating IL-1β in control and MOS+LM pigs increased (P < 0.05) on day 1 post-LPS challenge but did not change (P > 0.10) in MOS and LM groups. On day 15, pigs fed LM had decreased (P < 0.05) ileal crypt depth compared with pigs fed the control diet. On day 21, fecal propionate and butyrate tended to be lower (P < 0.10) in pigs fed MOS vs. control and MOS+LM diet. These preliminary findings suggest that feeding LM alone improved feed efficiency and ileal morphological structure during the first week of LPS challenge; additionally, feeding LM and MOS may have beneficial effects relative to immune biomarkers.

Natural Clinoptilolite

Abstract The effects of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) were evaluated in broilers challenged with lipopolysaccharide (LPS) in a 21-d feeding trial. A total of 288 one-day-old chickens were allocated into three treatment groups: control, NCLI (2%) and MCLI (2%). Half of the birds from each treatment group were challenged with either 0.9% NaCl solution or LPS (250 μg/kg body weight, orally administered) at 16, 18 and 21 d of age. Before the LPS challenge, no dietary effect on bird growth performance was found (P>0.05). When LPS was orally administered, no significant changes in growth performance of broilers was found (P>0.05). However, small intestinal morphology and development, malondialdehyde (MDA) content of the jejunual and ileal mucosa, and superoxide dismutase (SOD) activity of the ileal mucosa were significantly affected (P<0.05). Supplementation with NCLI and MCLI significantly decreased the MDA contents of the jejunual and ileal mucosa and improved the SOD activity of the ileal mucosa and the development of the small intestine compared with the control group (P<0.05). The results indicated that NCLI and MCLI additions in feed had protective effects on the gut health of broilers against LPS challenge.

Effects of a lipid-coated zinc oxide (ZnO) Shield Zn® (SZ) vs. ZnO were evaluated. Forty 25-d-old weanling pigs were fed a nursery diet supplemented with 100 mg kg−1 Zn with ZnO (ZnO-100), ZnO-2500, SZ-100, -200, or -400. All piglets were challenged orally with 5 × 108 colony-forming units of enterotoxigenic Escherichia coli K88 on day 7 and euthanized on day 14. The fecal consistency score (FCS) was less for the SZ group vs. ZnO-100 (P < 0.05). The intestinal villus height:crypt depth ratio and goblet cell density were greater for the SZ group vs. ZnO-100. By regression analyses, SZ-100 to -200 and SZ-300 to -400 were comparable to ZnO-2500 in the FCS and intestinal variables, respectively. The jejunal mucosal mRNA level did not differ between the SZ group and either ZnO group in insulin-like growth factor-I and multiple structural proteins and cytokines including zonula occludens protein (ZO) 1 and interleukin (IL) 10 except for lower ZO-1 and IL-10 mRNA levels for the SZ group than for ZnO-2500 and ZnO-100, respectively. The ZO-1 mRNA level regressed positively on the supplemental SZ concentration. Results suggest that SZ play a role in epithelial barrier function and inflammation by modulating the expression of ZO-1 and IL-10.

A total of 120 weanling pigs [(Landrace &times; Yorkshire) &times; Duroc], 21 days of age with an average initial body weight (BW) of 6.52 &plusmn; 0.22 (SE) kg were selected to investigate the effects of extruded rice product as a replacement for dried whey on growth performance, coefficient of total tract apparent digestibility (CATTD), blood profiles, faecal shedding of Lactobacillus and Escherichia coli (the microbial counts of digesta were expressed as log<sub>10</sub> colony forming units per gram), and faecal scores of weanling pigs. Pigs were randomly allocated to one of four dietary treatments, with six replicates per treatment and five pigs per pen. Pigs in the control group were fed a diet based on corn, soybean, and 20% dried whey. Experimental groups received the same diet as the control group, but dried whey was replaced by 3%, 6%, and 9% extruded rice. Throughout the experimental period (six weeks), no differences were observed in the average daily gain, average daily feed intake, and gain/feed ratio. Pigs fed 6% and 9% extruded rice had a lower (P &lt; 0.05) CATTD than pigs fed the control diet on Day 14. The blood creatinine concentration of pigs fed 9% extruded rice was higher (P &lt; 0.05) than that of pigs in the control group on Day 14. Pigs fed the diets containing 6% and 9% extruded rice had decreased (P &lt; 0.05) faecal E. coli counts on Day 14 compared with pigs fed the control diet. The current results indicate that feeding extruded rice can decrease faecal E. coli counts without negative effects on growth performance in weanling pigs.

A total of 125 crossbred pigs with an initial body weight (BW) of 7.66 ± 1.30 kg were randomly distributed into one of five dietary treatments. Each treatment had five replicate pens with five pigs per pen. Treatments were as followed: (1) CON, control diet; (2) zinc oxide (ZO), CON + 0.3% ZO; (3) ZOM, CON + 0.3% ZO + 0.1% microencapsulated organic acids and pure botanicals (MOP); (4) microencapsulated zinc oxide (MZO), CON + 0.03% MZO; and (5) MZOM, CON + 0.03% MZO + 0.1% MOP. The MZO group had higher (P = 0.03) final BW than ZO group and also had higher (P = 0.04, 0.01) average daily gain and gain/feed ratio compared with ZO group during days 15–34 and throughout the experimental period. The MZO and MZOM had higher (P < 0.05) apparent total tract digestibility (ATTD) of dry matter (DM) and energy than ZO. Less (P < 0.05) feces Escherichia coli shedding was observed in the ZOM and MZOM diets compared with CON; the MZO had lowered (P = 0.001) zinc level in feces than ZO and CON. In conclusion, results indicated that supplementation with 0.3% MZO could improve the growth performance and ATTD of DM; inclusion of 0.1% MOP could decrease feces E. coli shedding and also decrease the zinc level in feces in weanling pigs.

Abstract An experiment was conducted to test the hypothesis that a Buttiauxella phytase expressed in T. reesei can compensate the reduction in standardized total tract digestible (STTD) P, Ca, digestible energy (DE), and standardized ileal digestible (SID) AA in diets for pigs without impaired growth performance. A positive control diet (PC) was formulated to meet the requirement for STTD P and total Ca (0.33% STTD P and 0.60% Ca). A negative control diet (NC) was formulated with 0.18% STTD P and 0.45% Ca and with reduction of DE by 43 kcal/kg and SID AA by 0.01–0.02% vs. PC. Adding 250, 500, or 1,000 phytase units (FTU) per kg to the NC diet for a total of 5 experimental diets formulated three additional diets. A total of 155 pigs (BW: 8.77 ± 1.38 kg) were allotted to the 5 treatments, and there were 8 replicate pens per treatment. The experiment was conducted for 21 d. Pigs were weighed at the beginning and conclusion of the experiment, and daily feed allotments were recorded. Average daily gain (ADG), average daily feed intake (ADFI), and gain: feed ratio (G:F) were calculated for each treatment. Data were analyzed using contrast statements to compare PC and NC, PC and phytase, and to determine linear and quadratic effects of phytase. Results indicated that pigs fed the NC diet had reduced (P &lt; 0.05) ADG and G:F compared with pigs fed the PC diet (Table 1). Adding phytase to NC increased ADFI (linear, P &lt; 0.05) and ADG (quadratic, P &lt; 0.05) with the greatest values for the 1,000 FTU treatment. Including phytase in the diet also resulted in a quadratic increase (P &lt; 0.05) in G:F. In conclusion, Buttiauxella phytase may be included in diets with reduced nutrients and energy for weanling pigs without compromising pig growth performance.

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.

Casein glycomacropeptide (CGMP), a glycoprotein originating during cheese manufacture, has shown promising effects by promoting the growth of some beneficial bacteriain vitro, although its activity has not been well explored. The present study was designed to evaluate the effects of CGMP against enterotoxigenicEscherichia coli(ETEC) K88in vitro(Trial 1) andin vivo(Trial 2). In Trial 1, increasing concentrations of CGMP (0, 0·5, 1·5 or 2·5 mg/ml) were tested regarding its ability to block the attachment of ETEC K88 to ileal mucosa tissues obtained from piglets. Increasing the concentration of CGMP resulted in a gradual decrease in ETEC K88 attachment to the epithelial surface. In Trial 2, seventy-two piglets were distributed in a 2 × 2 factorial combination including or omitting CGMP in the diet (control dietv.CGMP) and challenged or not with ETEC K88 (yesv.no). Inclusion of CGMP increased crude protein, ammonia and isoacid concentrations in colon digesta. CGMP also increased lactobacilli numbers in ileum and colon digesta, and reduced enterobacteria counts in mucosa scrapings and the percentage of villi withE. coliadherence measured by fluorescencein situhybridisation. The inclusion of CGMP in the diets of challenged animals also prevented the increase of enterobacteria in ileal digesta. We can conclude that CGMP may improve gut health by diminishing the adhesion of ETEC K88 to the intestinal mucosa, by increasing the lactobacilli population in the intestine and by reducing the overgrowth of enterobacteria in the digestive tract of piglets after an ETEC K88 challenge.
