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 < 0.050) (SAS, 2009). Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The Kruskal Wallis test was used to compare microbial biodiversity (P < 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.

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 < 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 < 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 < 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 < 0.05) digesta viscosity (1.91 to 1.48 mPa.s); increased (P < 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 < 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.
