Lipid Supplement

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 < 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.

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.

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.

Supplemental Effects

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.

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.
