Oil Blend

Abstract This study was to investigate the role of castor oil and cashew nutshell liquid (functional oil blend, FOB) on intestinal health and growth performance of nursery pigs and to determine an optimal supplemental level. Newly weaned pigs (20 barrows and 20 gilts at 25 d of age, 7.02 ± 0.58 kg BW) were randomly allotted to 5 treatments in a RCBD and fed in 2 phases (13 and 21 d respectively) with increasing levels (0, 0.050, 0.075, 0.100, and 0.150%) of FOB. Growth performance was measured by each phase. Titanium dioxide (0.4%) was added to phase 2 diets as an indigestible marker to measure AID. On d 34, all pigs were euthanized to collect jejunum to measure immune status, oxidative stress status, microbiota, morphology, and crypt cell proliferation. Data were analyzed using Proc Mixed of SAS. Supplementation of FOB did not affect the overall growth performance. Supplementation of FOB tended to decrease (P = 0.064) the concentration of jejunal protein carbonyl (3.11 to 2.45 nmol/protein) and tended to increase villus height (P = 0.098, 401 to 453 μm) and crypt depth (P = 0.070, 86 to 99 μm). Increasing FOB reduced (P < 0.05) relative abundance of Helicobacteraceae (46.8 to 21.0%) and increased (P < 0.05) relative abundance of Prevotellaceae (7.9 to 13.1%), Burkholderiaceae (6.3 to 10.8%) and Pseudomonadaceae (0.1 to 1.0%), and increased (P < 0.05) alpha diversity of the jejunal mucosa-associated microbiota at the family level (Chao1 index 42.8 to 56.8%). In conclusion, FOB showed potential benefits on intestinal health of nursery pigs by increasing beneficial and reducing harmful bacteria reducing oxidative damages in the jejunal mucosa, and by enhancing villus structure, whereas without affecting the growth performance. The FOB at a range of 0.050% to 0.150% provided the most benefit for nursery pigs.

Functional Oils

This study aimed to investigate the effects of functional oils on modulation of mucosa-associated microbiota, intestinal health, and growth performance of nursery pigs. Forty newly weaned pigs (20 barrows and 20 gilts) with 7.0 ± 0.5 kg body weight (BW) were housed individually and randomly allotted in a randomized complete block design with sex and initial BW as blocks. The dietary treatments were a basal diet with increasing levels (0.00, 0.50, 0.75, 1.00, and 1.50 g/kg feed) of functional oils (a blend of castor oil and cashew nutshell liquid; Oligo Basics USA LLC, Cary, NC) fed to pigs for 34 days divided in two phases (P1 for 13 days and P2 for 21 days). Growth performance was analyzed weekly. On day 34, all pigs were euthanized to collect jejunal mucosa for analyzing the mucosa-associated microbiota and intestinal health, and ileal digesta for analyzing apparent ileal digestibility. Data were analyzed using SAS 9.4. Supplementation of functional oils did not affect the overall growth performance. Increasing supplementation of functional oils reduced (p < 0.05) the relative abundance of Helicobacteraceae, whereas it increased (p < 0.05) Lactobacillus kitasatonis. Supplementation of functional oils tended (p = 0.064) to decrease protein carbonyl and increase the villus height (p = 0.098) and crypt depth (p = 0.070). In conclusion, supplementation of functional oils enhanced intestinal health of nursery pigs by increasing beneficial and reducing harmful bacteria, potentially reducing oxidative stress and enhancing intestinal morphology, without affecting overall growth performance of pigs. Supplementation of functional oils at 0.75–1.50 g/kg feed was the most beneficial to the jejunal mucosa-associated microbiota and intestinal integrity of nursery pigs.

Abstract The effects of encapsulated sodium butyrate (SB), phytogenics (PH), or a combination were studied on intestinal health of nursery pigs. Phytogenics were blends of dry herbs and essential oil components. Forty-eight weaned pigs (21-d-old; 6.9 ± 0.6 kg BW) were individually housed, blocked by initial BW and sex, allotted to 4 dietary treatments (n = 12) in a RCBD, and fed for 33-d (P1: 0–7; P2: 7–19; and P3: 19–33). Treatments were arranged by 2 factors: SB (P1: 0.2% and P2: 0.1%) and PH (P3: 0.033%). Diets were formulated to meet or exceed NRC (2012) nutrient requirements and pigs were fed ad libitum. For each phase, ADG, ADFI, and G:F were measured. Fecal scores were assessed during d 3–19 and d 26–33. Blood samples were drawn in P2 and P3 to measure tumor necrosis factor alpha (TNF-α), IL-6, and immunoglobulin G (IgG). Four pigs at P2 and 8 pigs in P3 from each treatment were euthanized to collect jejunal tissue, jejunal mucosa, and ileal digesta to measure gut histology, TNF-α, IL-6, myeloperoxidase (MPO), malondialdehyde (MDA), and protein carbonyl. Data were analyzed using PROC MIXED of SAS. Fixed effects were treatments and random effects were blocks. In P2 and P1-2, SB decreased (P &lt; 0.05) ADFI whereas no effect on ADG and G:F. In P2, SB tended to decrease (P = 0.063) villus height to crypt depth ratio (VH:CD) whereas increased (P &lt; 0.05) enterocyte proliferation in P3. In P3 and overall, PH increased (P &lt; 0.05) G:F. No changes were found in TNF-α, IL-6, MPO, MDA, IgG, and protein carbonyl. Conclusively, SB and a combinational use of SB and PH showed minimal effects on growth performance and gut health when added to the diets of nursery pigs. However, PH supplementation increased feed efficiency of nursery pigs during 19–33 d post-weaning.

Abstract This study aimed to determine supplemental effects of xylanase (endo-β-1,4-xylanase, CJ BIO, Korea) and its optimal supplementation level on viscosity of jejunal digesta, nutrient digestibility, intestinal health, and growth performance of pigs. Sixty weaned pigs (6.9 ± 0.8 kg BW) were randomly allotted to 5 treatments based on a RCBD with initial BW and sex as block and fed in 3 phases (P1/2/3 for 10/14/14 d, respectively). Dietary treatment were the supplementation levels of xylanase providing (0, 220, 440, 880, and 1,760 XU/kg feed). Titanium dioxide (0.4%) was added to P3 diets as an indigestible marker to measure AID. On d 38, all pigs were euthanized to collect ileal and jejunal digesta to measure AID and viscosity, respectively; jejunal mucosa and tissue to measure intestinal health parameters. Data were analyzed using SAS 9.4. Xylanase supplementation from 0 to 350 XU/kg increased (P &lt; 0.05) ADG (596 to 746 g/d) during the last week, whereas there was no effect by xylanase on the overall growth performance. Increasing xylanase supplementation reduced (P &lt; 0.05) digesta viscosity (1.91 to 1.48 mPa.s); increased (P &lt; 0.05) the AID of EE (83.9 to 89.5%), NDF (52.9 to 56.9%) and ADF (35.3 to 39.3%); tended to reduce Cupriavidus (P = 0.073; 1.33 to 0.63%) and Megasphaera (P = 0.063; 1.26 to 0.23%); and tended to increase Succinivibrio (P = 0.076; 1.10 to 2.71%) and Pseudomonas (P = 0.060; 4.89 to 13.29%). Xylanase supplementation from 0 to 520 XU/kg reduced (P &lt; 0.05) jejunal MDA (0.99 to 0.58 µmol/mg protein). In conclusion, xylanase supplementation showed benefits on intestinal health by reducing digesta viscosity, oxidative stress status, and harmful bacteria in the jejunal mucosa and by increasing the AID of nutrients. Xylanase supplementation at a range of 350 to 520 XU/kg feed provided the most benefits.

Abstract This study investigated the effects of Bacillus sp. on intestinal health and prevention of diarrhea by F18+ Escherichia coli (ETEC) in nursery pigs. Forty-eight weaned pigs (7.9 ± 0.5 kg BW) were allotted to 4 treatments with 12 replicates (NC: no-challenge; PC: challenge/no-treat; BMD: challenge/bacitracin; BAC: challenge/Bacillus sp. at 109 CFU/kg feed). All pigs were fed diets for 28 d. At d 7, challenged groups were orally inoculated with ETEC (1.8 × 1010 CFU) and NC group received sterile solution. Growth performance was analyzed weekly and pigs were euthanized on d 28 to measure intestinal health. Data were analyzed using SAS 9.4. There were no difference on growth performance among treatments during pre-challenge period. From d 7 to 14, PC tended to reduce (P = 0.067) ADG (352 to 440 g/d), whereas no effect was observed during the overall period. The PC increased (P &lt; 0.05) fecal score at d 7 (post-challenge) (4.1 to 3.3) and d 8 (4.1 to 3.3), whereas BMD decreased (P &lt; 0.05) it at d 9 (4.3 to 3.5) and d 11 (3.8 to 3.3). The PC increased (P &lt; 0.05) MDA (0.56 to 0.30 μmol/mg protein) and tended to increase TNFα (P = 0.084; 0.89 to 1.04 pg/mg protein), whereas BMD and BAC reduced (P &lt; 0.05) MDA (0.56 to 0.31, 0.29 μmol/mg protein) and TNFα (1.04 to 0.81, 0.77 pg/mg protein) in jejunal mucosa. The PC reduced (P &lt; 0.05) α-diversity (Chao1: 32.3 to 19.4), whereas BAC increased it (Chao1: 19.4 to 30.7) whereas BMD increased (P &lt; 0.05) it (Shannon: 1.85 to 2.44; Simpson: 0.55 to 0.70) of jejunal mucosa-associated microbiota. In conclusion, ETEC challenge caused diarrhea, increased immune response, and oxidative stress by disrupting mucosa-associated microbiota. The BMD and BAC reduced jejunal immune response and oxidative stress by restoring mucosa-associated microbiota.

Abstract This study determined the supplemental effects of Lactobacillus extract (LBE) postbiotics on intestinal health and prevention of postweaning diarrhea caused by F18+ Escherichia coli (ETEC) in nursery pigs. Sixty-four weaned pigs (6.6 ± 0.7 kg BW) were allotted in a RCBD to 4 dietary treatments (NC: no-challenge; PC: challenge/no-treat; BMD: challenge/bacitracin; LBE: challenge/LBE 0.2%) and fed diets for 28 d. At d 7, challenged groups were orally inoculated with ETEC (2.4 x 1010 CFU) and NC group received sterile solution. Growth performance was analyzed weekly and pigs were euthanized on d 28 to measure intestinal health. Data were analyzed using the SAS 9.4. During post-challenge period, PC tended to decrease (P = 0.067) ADG (373 to 284 g/d), whereas BMD increased (P &lt; 0.05) ADG (284 to 408 g/d); LBE tended to increase (P = 0.081) ADG (284 to 370 g/d). PC increased fecal score (P &lt; 0.05, 3.4 to 3.9) on d 14, whereas BMD decreased it (P &lt; 0.05, 3.9 to 3.5) on d 21. PC increased (P &lt; 0.05) protein carbonyl (0.76 to 1.12 nmol/mg protein), crypt cell proliferation (28 to 36%), and Helicobacter rodentium (0.4 to 3.7%). However, BMD decreased (P &lt; 0.05) crypt cell proliferation (36 to 32%) and Helicobacter spp. (15.0 to 1.4%); and increased (P &lt; 0.05) villus height (309 to 377 µm), Bifidobacterium boum (0.04 to 2.0%), Pelomonas spp. (1.5 to 8.5%), and Microbacterium ginsengisoli (0.5 to 3.0%). LBE reduced (P &lt; 0.05) crypt cell proliferation (36 to 27%) and Helicobacter rodentium (3.7 to 0.04%); and increased (P &lt; 0.05) Lactobacillus salivarius (0.3 to 4.1%) and Propionibacterium acnes (0.4 to 7.4%). Collectively, ETEC reduced growth performance by adversely affecting microbiota and intestinal health. BMD and LBE improved growth performance by enhancing intestinal health and increasing beneficial microbiota in ETEC challenged pigs.

Diarrhea Incidence

Abstract Antibiotics growth promoting (AGP) in animal feed has been restricted. With this, several additives have been tested in order to replace AGP and ensure intestinal health. The objective of this study was to evaluate the effects of a blend of additives on growth performance, diarrhea incidence and cecal content microbiota of nursery pigs. A total of 576 weaned pigs (6.21 ± 1.16 kg) were assigned into 4 treatments (12 replicates) in randomized block design: basal diet without additives (NC); basal diet with 120 ppm of halquinol (PC); NC + 0,05% blend of lactic acid (3,5%), benzoic acid (2,5%), flavonoids (3,5%) (B5); NC+ 0,1% of same blend (B10). The pigs were weighed 0 and 42 days into the experiment. On day 10, one animal per pen (10 replicates) was euthanized for microbiota analyses. The diarrhea incidence was calculated by the percentage of visual pens with diarrhea, by day, in the period. The growth performance was analyzed by GLIMMIX procedure and the means were compared with Tukey test (P &lt; 0.050) (SAS, 2009). Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The Kruskal Wallis test was used to compare microbial biodiversity (P &lt; 0.050) by statistical program STAMP. The final weight (P = 0.010) and average daily gain (P = 0.001) of B10 and PC were higher than NC. Regarding diarrhea, it was observed that the B5 and B10 had lower incidence when compared to other groups in the total period. In the microbiome analyses, it was observed that the B5, B10, and PC groups had lower (P = 0.021) biodiversity when compared to the NC piglets. However, the B5 and B10 group had higher biodiversity when compared to the PC group. In conclusion, the supplementation with 0,1% blend of additives can be a substitute for AGP.

Abstract This study aimed to evaluate supplemental effects of milk carbohydrates in whey permeate on jejunal mucosa-associated microbiota in nursery pigs during 7 to 11 kg BW. A total of 720 pigs at 7.5 kg BW were allotted to 6 treatments (6 pens/treatment and 20 pigs/pen). Treatments were 6 levels of whey permeate supplementation (0, 3.75, 7.50, 11.25, 15.00, and 18.75%) and fed to pigs for 11 d. On d 11, 36 pigs representing median BW of each pen were euthanized to collect the jejunal mucosa to evaluate microbiota in the jejunum by 16S rDNA sequencing. Data were analyzed using contrasts in MIXED procedure of SAS. Whey permeate contained 76.3% lactose and 0.4% milk oligosaccharides. Increasing whey permeate supplementation from 0 to 18.75% did not affect the alpha-diversity estimates of microbiota. Whey permeate supplementation tended to decrease (P = 0.073, 1.59 to 1.22) Firmicutes:Bacteroidetes compared with no addition of whey permeate. Increasing whey permeate supplementation tended to linearly increase Bifidobacteriaceae (P = 0.089, 0.73 to 1.11), decrease Enterobacteriaceae (P = 0.091, 1.04 to 0.52), decrease Stretococcaceae (P = 0.094, 1.50 to 0.71), and caused quadratic changes (P &lt; 0.05) on Lactobacillaceae (maximum: 9.14% at 12.91% whey permeate). Increasing whey permeate supplementation caused a quadratic change (P &lt; 0.05) on Lactobacillus_Salivarius (maximum: 0.92% at 7.35% whey permeate) and tended to cause quadratic changes on Lactobacillus_Rogosae (P = 0.083; maximum: 0.53% at 8.45% whey permeate) and Lactobacillus_Mucosae (P = 0.092; maximum: 0.70% at 6.98% whey permeate). In conclusion, supplementation of whey permeate as sources of lactose and milk oligosaccharides at a range from 7 to 13% seems to be beneficial to nursery pigs by increasing the abundance of lactic acid-producing bacteria in the jejunal mucosa.

Abstract The efficacy of mycotoxin deactivators on health and growth performance of newly weaned pigs (27 d-old) fed diets naturally contaminated with deoxynivalenol was investigated. Sixty pigs were housed individually and assigned to 5 treatments for 34 d subdivided into 3 phases: NC (no added deoxynivalenol); PC (deoxynivalenol at 2 mg/kg); CYC (PC + clay/yeast culture based product, 0.2%); CYE (PC + clay/yeast cell wall/plant extracts/antioxidants based product, 0.2%); and CYB (PC + clay/inactivated yeast/botanicals/antioxidants based product, 0.2%). Blood was taken at d 14 and 34. Intestinal mucosa was taken at d 34. Data were analyzed using Proc Mixed of SAS with pre-planned contrasts. Deoxynivalenol reduced (P &lt; 0.05) ADG in P3. Pigs fed CYC had greater (P &lt; 0.05) ADG during overall period, ADFI during P3, and gain/feed during P2 than PC. At d 14, deoxynivalenol reduced (P &lt; 0.05) BUN/creatinine and tended to reduce (P = 0.088) BUN. Pigs fed CYB tended to have greater (P = 0.059) AST than PC. At d 34, pigs fed CYC (P = 0.083) and CYB (P = 0.068) tended to have lower serum CPK than PC. Pigs fed CYE had lower (P &lt; 0.05) BUN/creatinine than PC. Deoxynivalenol tended to increase (P = 0.068) malondialdehydes and decrease (P = 0.072) glutathione in jejunal mucosa. Pigs fed CYE and CYB had lower (P &lt; 0.05) malondialdehydes, whereas pigs fed CYB had greater (P &lt; 0.05) glutathione and tended to have lower (P = 0.079) jejunal IgA than PC. Pigs fed CYC (P = 0.066) and CYE (P = 0.099) tended to have lower jejunal IL8 than PC. In conclusion, deoxynivalenol compromised growth performance and intestinal health. The mycotoxin deactivators could enhance intestinal health of pigs fed diets with deoxynivalenol without affecting liver function.

Abstract This study aimed to evaluate the effects of increasing levels of β-glucanase on modulation of jejunal mucosa-associated microbiota in relation to nutrient digestibility and intestinal health of pigs fed diets with 30% corn DDGS and xylanase. Forty pigs at 12.4 ± 0.5 kg BW were allotted in a RCBD with initial BW and sex as blocks. Dietary treatments consisted of a basal diet with xylanase (1,500 EPU/kg) and increasing levels of β-glucanase (0, 200, 400, and 600 U/kg) meeting nutrient requirements and fed to pigs for 21 d. Blood samples were collected at d 19. At d 21, all pigs were euthanized to collect intestinal tissues and digesta. Tumor necrosis factor alpha (TNFα), IL-6, and MDA were measured in plasma and mid-jejunal mucosa. Viscosity was determined using digesta from the distal jejunum. Ileal and rectal digesta were evaluated to determine AID and ATTD of nutrients. Mucosa samples from the mid-jejunum were utilized for microbiota sequencing. Data were analyzed using the MIXED procedure on SAS 9.4. Overall, increasing dietary β-glucanase tended to increase (Linear; P = 0.077) the ADG of pigs. Increasing dietary β-glucanase affected (quadratic; P &lt; 0.05) the relative abundance of Bacteroidetes, reduced (linear; P &lt; 0.05) Helicobacter rappini, whereas increased (Linear, P &lt; 0.05) Faecalibacterium prausnitzii. β-glucanase supplementation (0 vs. others) tended to increase (P = 0.096) the AID of CP in the diet, whereas increasing dietary β-glucanase tended to increase (Linear; P = 0.097) the ATTD of GE in the diet and increased (Linear; P &lt; 0.05) the concentration of IL-6 in the plasma of pigs. In conclusion, increasing β-glucanase up to 600 U/kg feed in a diet containing xylanase (1,500 EPU/kg) modulated mucosa-associated microbiota by increasing the relative abundance of beneficial bacteria and reducing potentially harmful bacteria. Furthermore, increasing β-glucanase up to 600 U/kg feed in a diet containing xylanase (1,500 EPU/kg feed) enhanced the status of intestinal environment and nutrient utilization, as well as reduced systemic inflammation of pigs, collectively resulting in moderate improvement of growth performance. Supplementing β-glucanase at a range of 312 to 410 U/kg with xylanase at 1,500 EPU/kg feed showed the most benefit on jejunal mucosa-associated microbiota and reduced systemic inflammation of pigs.

Abstract This study evaluated supplemental effects of increasing levels of soy protein concentrate (SPC) replacing animal protein supplements on growth performance and intestinal health of nursery pigs. Thirty-two newly weaned pigs (6.4 ± 0.4 kg BW) were allotted to 4 treatments in a RCBD with initial BW and sex as blocks and fed for 35 d in 3 phases (P1/2/3 for 10/12/13 d, respectively) following NRC (2012). Dietary treatments were SPC-0 (diet with fish meal 4/2/1%, poultry meal 10/8/4%, and blood plasma 4/2/1% for P1/2/3, respectively); SPC-1, SPC-2, and SPC-3 (SPC-0 with SPC replacing 1/3, 2/3, and 3/3 of animal protein supplements). Titanium dioxide (0.4%) was added to the diets as indigestible marker from d 30. Growth performance was recorded for each phase. Pigs were euthanized on d 35 to collect jejunal tissue to measure intestinal health, and ileal digesta to measure apparent ileal digestibility (AID) of nutrients. Data were analyzed using the MIXED procedure of SAS. Overall, increasing levels of SPC replacing animal proteins reduced linearly (P &lt; 0.05) the BW (21.4 to 17.3 kg), ADG (431 to 312 g/d), and ADFI (551 to 390 g/d) of pigs. The G:F decreased linearly (P &lt; 0.05) on P1 (0.72 to 0.52). Increasing levels of SPC replacing animal proteins did not affect the AID of nutrients. Immunoglobulin A tended to increase (P = 0.099, 3.39 to 5.55 mg/mg of protein) when SPC supplemental levels were compared with the control group. Increasing levels of SPC replacing animal proteins did not affect the concentration of MDA, TNF-a, IL-8, protein carbonyl, and IgG and villus height, villus width, and crypt cells proliferation among treatments. Collectively, increasing level of SPC supplement did not negatively affect the intestinal health and digestibility of nutrients, whereas linearly reduced the growth performance.
