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.

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.

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 &lt; 0.05) relative abundance of Helicobacteraceae (46.8 to 21.0%) and increased (P &lt; 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 &lt; 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.

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 The objective was to evaluate Yarrowia lipolytica (YL) as a lipid supplement fed to nursery pigs for the growth performance and apparent ileal digestibility (AID). Twenty-four pigs weaned at 21 d of age (12 barrows and 12 gilts with initial BW at 7.2 ± 0.6 kg) were allotted to 3 dietary treatments (n = 8) based on the randomized complete block design with sex and BW as blocks. The main effect was the dietary supplementation of YL (0, 1.5, and 3.0%, replacing poultry fat) with nutrients meeting or exceeding the requirements by NRC (2012) and fed to pigs for 21 d based on 2 phases. Feed intake and BW were recorded at d 0, 10, and 21 to calculate ADG, ADFI, and G:F. Fecal scores were recorded at every odd day from d 3 to 19. Pigs were euthanized on d 21 to collect ileal digesta for AID of nutrients in diets. Data were analyzed using Proc Mixed of SAS. There were no differences in growth performance among treatments. Whereas, pigs fed 0 and 1.5% YL had higher (P &lt; 0.05) AID of DM (55.0 and 52.2% to 40.2%, respectively) and GE (62.1 and 60.6% to 49.8%, respectively) than pigs fed 3% YL. There were no differences in AID of DM and GE between the pigs fed 0% and 1.5% YL. In conclusion, 1.5% Yarrowia lipolytica could be supplemented in nursery pig diets reducing 0.8% of poultry fat without affecting growth performance and AID of DM and GE.

Abstract The objectives were to determine the digestible energy, standardized ileal digestibility of AA, and growth performance of dietary spray-dried plasma protein (SDPP) in nursery pigs. In Exp. 1, twelve nursery barrows (9.8 ± 0.9 kg) were assigned to a quadruplicated 3 × 2 Latin square design with 3 diets and 2 periods. Each period consisted of 5 days of adaptation, 2 days of fecal sampling, and 2 days of ileal collection. A basal diet was composed of corn, soybean meal, dried whey, and sucrose as the sole energy and AA sources. Experimental diets were prepared by replacing 15% of the energy and AA sources in the basal diet with SDPP 1 (manufactured in the US; 78.2% CP and 4,862 kcal GE/kg as-is) or SDPP 2 (manufactured in Korea; 74.3% CP and 4,636 kcal GE/kg as-is). Spray-dried plasma protein 1 had greater digestible energy (4,799 vs. 4,469 kcal/kg as-is; P &lt; 0.05), but less (P &lt; 0.05) standardized ileal digestibility of lysine, methionine, tryptophan, and threonine compared with SDPP 2. In Exp. 2, eighty-four nursery pigs (7.9 ± 0.7 kg) were allotted to 3 dietary treatments in a randomized complete block design with 7 replicate pens and 4 pigs per pen. Three corn-soybean meal-whey-based diets contained fish meal (6% and 3.5% for d 0 to 14 and d 14 to 28, respectively), SDPP 1 (4.5% and 2.7%), or SDPP 2 (5% and 3%) to maintain same energy and nutrient concentrations. During d 0 to 14 and overall period, pigs fed the diets containing SDPP gained more weight (P &lt; 0.05) than those fed the fish meal diet with no difference between 2 sources of SDPP. Overall, 2 sources of SDPP have different energy concentrations and AA digestibility, but similar growth promoting effects in nursery pigs.

Xylanase exerts key roles in improving growth performance and intestinal health of broilers fed wheat-based diets. However, knowledge is limited regarding effects of xylanase supplementation on ileal microbiota in broilers. A total of 128 one-day-old broilers (initial BW 48.03 ± 0.33 g) were selected to investigate effects of xylanase (AT-xynA) on growth performance, ileal morphology, microbiota composition, immune response, antioxidant capacity, and endocrine peptide levels in broilers. Broilers were randomly allotted into two dietary treatments (n = 8), namely, a wheat-soybean basal diet and a basal diet with 4,000 U/kg AT-xynA (XY). On days 7, 14, 21, and 42, broilers were weighted and ileal tissues were sampled. Ileal digesta samples were collected for analyzing microbiota composition on days 21 and 42. The results showed that AT-xynA could improve average daily weight gain and average daily feed intake, and there were interactions between diet and age of broilers (p &lt; 0.05). On days 21 and 42, xylanase supplementation decreased ileal microbiota α-diversity, and the relative abundance of potentially pathogenic microbiota, such as phylum Proteobacteria, family Moraxellaceae and Staphylococcaceae, genus Staphylococcus, Pseudomonas, Streptococcus, and Enterococcus, increased the abundance of Lactobacillus (p &lt; 0.05). Moreover, the reduction in acetate concentration and abundance of short-chain fatty acid-producing bacteria was also observed in broilers from XY group (p &lt; 0.05). AT-xynA increased ileal villus height, glucagon-like peptide-1, and insulin-like growth factor-1 concentrations and decreased interleukin-1β, interleukin-6, tumor necrosis factor-α, and malondialdehyde content in broilers, and these positive effects on intestinal health were greater in young broilers. In conclusion, xylanase supplementation to wheat-based diets could improve ileal intestinal morphology and immune function, and alleviate excess fermentation of bacteria, which may be related to changes of intestinal microbiota. In addition, the positive effects of xylanase on intestinal health were more pronounced in young broilers, thus contributing to subsequent improvement in growth performance of broilers.

Abstract Background Eucommia ulmoides flavones (EUF), have been demonstrated to attenuate the inflammation and oxidative stress of piglets. This study was designed to test whether EUF could be as an antibiotic alternative to support growth performance and maintain intestinal health in weanling-piglets. Weaned-piglets (n = 480) were assigned into 3 groups and fed with a low-protein basal diet (NC), or supplementation with antibiotics (PC) or 0.1‰ EUF (EUF). Blood, intestinal contents and intestine were collected on d-15 and d-35, respectively. Results The results showed that the body weight on d-35, average daily gain and gain : feed from d 15 to d 35 and d 0 to d 35 in piglets of PC and EUF treatments were higher than (p < 0.05) these in NC treatment, whereas PC and EUF treatments decreased (p < 0.05) the diarrhea index of weanling piglets. Dietary supplementation of EUF significantly enhanced (p < 0.05) the serum concentrations of total protein, alanine transaminase and the immunoglobulin G on d-15 of piglets compared to piglets in NC treatment. EUF supplementation increased (p < 0.05) the jejunal and ileal villus height and the population of ileal lactic acid bacteria on d-15 but remarkable decreased (p < 0.05) the population of ileal coliform bacteria on d-15 and d-35. Conclusion These findings indicated the antibiotic alternative capacity of EUF in piglets exhibiting by improving growth performance and intestinal morphology, decreasing colonization of coliform bacteria and diarrhea index in weanling piglets.

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.

This study aimed to investigate the effects of chronic exposure to low levels of dietary aflatoxin B1 (AFB1) on growth performance, apparent total tract digestibility and intestinal health in pigs. In a 102-day experiment, fourteen barrows (Duroc×Landrace×Yorkshire, initial BW = 38.21 ± 0.45 kg) were randomly divided into control (CON, basal diet) and AFB1 groups (the basal diet supplemented with 280 μg/kg AFB1). Results revealed that the AFB1 exposure decreased the final BW, ADFI and ADG in pigs (p < 0.10). AFB1 exposure also decreased the apparent total tract digestibility of dry mater and gross energy at 50 to 75 kg and 105 to 135 kg stages, and decreased the apparent total tract digestibility of ether extract at 75 to 105 kg stage (p < 0.05). Meanwhile, AFB1 exposure increased serum diamine oxidase activity and reduced the mRNA abundance of sodium-glucose cotransporter 1, solute carrier family 7 member 1 and zonula occluden-1 in the jejunal mucosa (p < 0.05). Furthermore, AFB1 exposure decreased superoxide dismutase activity (p < 0.05) and increased 8-hydroxy-2′-deoxyguanosine content (p < 0.10) in jejunal mucosa. AFB1 exposure also increased tumor necrosis factor-α, interleukin-1β and transforming growth factor-β mRNA abundance in jejunal mucosa and upregulated Escherichia coli population in colon (p < 0.05). The data indicated that chronic exposure to low levels of dietary AFB1 suppressed growth performance, reduced the apparent total tract digestibility and damaged intestinal barrier integrity in pigs, which could be associated with the decreased intestinal antioxidant capacity and the increased pro-inflammatory cytokine production.
