Weaning Piglets

Abstract A total of 38 mixed parity sows were used from 28-d of gestation until weaning to determine the effects of medium chain fatty acids (MCFA) in sow and nursery pig diets on litter characteristics and growth performance. On 28-d of gestation, sows were blocked by parity and body weight (BW), and allotted to either a control diet (UNSUP) or a control diet plus 0.3% inclusion of DaaFit Plus (MCFA) fed during gestation and lactation. At weaning, piglets (n=432) were allocated in a 2x2 factorial based on maternal diet (UNSUP or MCFA) and post-weaning diet (UNSUPnurs or MCFAnurs) in a 3-phase nursery pig feeding program lasting 42 days. Individual piglets were weighed at birth, 7-d, at weaning and every 2 weeks post-weaning. A flu outbreak occurred during the latter part of gestation leading to high overall stillborn rate (11%). There was no impact of MCFA supplementation on sow performance (P>0.14). During the suckling period, MCFA fed to sows had no impact on piglet weights or ADG (P>0.82). In the nursey period, overall gain (0.112±0.02 kg) was low in the first two weeks possibly due to health challenges. Supplementation of MCFA to sows or nursery pigs had no impact on body weights during the nursery period (P>0.32); however, absolute differences between groups increased with week [wean, 0.10kg; wk 2, 0.14kg; wk 4, 0.71kg; wk 6, 0.83kg) to the advantage of MCFA fed pigs. Pigs from MCFA fed sows had greater feed intake (P< 0.02) from 14 to 28-d and decreased gain:feed (P < 0.04) from 28 to 42-d compared to pigs from UNSUP sows. Overall, sow and nurser-y pigs fed MCFA had numerically greater 42-d BW, ADG, and ADFI. In conclusion, despite health challenges, supplementation with MCFA in gestation, lactation or in the nursery period improved piglet performance.

Abstract Although microalgae can be used as a source of energy and macronutrients in pig diets, there is limited information on the use of partially de-oiled microalgae coproducts in swine feeding programs. The objectives of this study were to evaluate the effects of a partially de-oiled microalgae extract (MAE) in nursery pig diets on growth performance and health status. A total of 300 pigs (initial BW = 6.3 ± 2.1 kg) were used in a 42-d experiment. Treatments included a standard corn-soybean meal control diet, and diets containing 1, 5, 10, or 20% MAE replacing primarily corn. The ME content of MAE was calculated from the chemical composition, and diets were formulated to meet or exceed nutrient requirements for nursery pigs. Pigs were stratified by weaning BW into 12 blocks in a randomized complete block design, with sex distributed evenly among blocks. Pens of pigs (5 pigs/pen) were assigned randomly within block to one of five dietary treatments. Pig BW and feed disappearance were recorded weekly. On day 42, 30 pigs were harvested and sections of the jejunum and ileum were collected for gut morphology analysis, and a liver sample was collected for metabolomic analysis using liquid chromatography-mass spectroscopy. Data were analyzed by ANOVA with diet as treatment effect, and contrasts were used to test linear or quadratic effects of dietary MAE inclusion level. Overall, pigs fed 1% and 5% MAE had the greatest (quadratic P < 0.05) ADG, resulting from greater (quadratic P < 0.05) ADFI. There was a tendency for a greater number of pigs requiring injectable treatments (P = 0.16) and a greater mortality (P = 0.14) in pigs fed the control diet than pigs in any of the diets with the MAE. Final BW increased (P < 0.05) for pigs fed 1% and 5% MAE diets. The improvements in ADG were not explained by differences in mucosa height or goblet cell count among dietary treatments. Pigs fed diets containing 1% or 5% MAE had relatively less concentration (P < 0.05) of ammonia in the liver and had changes in metabolites associated with the urea cycle. In conclusion, feeding MAE resulted in increased growth responses and may have beneficial health effects when fed to nursery pigs.

Abstract A total of 2,304 newly weaned pigs (5.8±0.06 Kg BW, ~21-day old, DNA Genetics) were used in a RCBD to evaluate the effect of a direct-fed microbial (DFM) program on pig performance and survivability, under commercial pig production. Pigs were housed in 2 barns (blocking factor) with 36 pens each (32 pigs/pen, mixed-sex), and pens randomized to treatments: Control or DFM program (36 pens/treatment). The program consisted of a DFM (blend 1) delivered through drinking water (1.32x108 CFU/pig/day) from day 0 to 7, followed by another DFM (blend 2) in feed (1.5x105 CFU/g of feed) from day 7 through 49. Those DFM consisted of spore-forming Bacillus sp. selected to inhibit enterotoxigenic E. coli growth (blend 1) and reduce local inflammation (blend 2). The feeding program included phases 1 and 2 (7 days each) in pellet, and phases 3 (11 days) and 4 (24 days) in meal. Phase 1 feeds included antibiotics Chlortetracycline and Tiamulin; both phase 4 feeds included Carbadox. A severe diarrhea outbreak was observed in week 3; antibiotic therapy (Neomycin, Sulfadiazine or Trimethoprim) throughout drinking water was used in both treatments alike between days 19 and 28. Pig and feed weight were recorded by pen; ADG and ADFI were calculated on pig-days. Pigs removed included mortality and those ill, nonresponsive to antibiotics. Performance data were analyzed by ANOVA, using the GLM procedure. Pigs removed did not follow normal distribution and was analyzed using a parametric survival option with days as time variable (JMP v14.2.0). No differences were detected through day 25. Pigs in DFM consumed less feed (923 vs. 951 g/d; SEM=10.33; P=0.05) and were more efficient (0.61 vs. 0.59 kg/kg; SEM=0.004; P< 0.05) from days 25 to 49. Total pigs removed were reduced (P< 0.05) by 23% in DFM vs. Control (Table 1). In conclusion, the DFM program improved nursery pig survivability and late performance, under commercial pig production that included a diarrhea outbreak and antibiotic therapy.

Abstract The objective was to evaluate the independent and additive effects of Cordyceps mushroom powder and carbadox to pharmacological copper+zinc in nursery pig diets. Two hundred-ten crossbred weanling pigs [(Duroc × (York × Landrace)] avg. 19 d of age and 5.8 kg were used in a 33 day growth trial. Pigs were alloted by weight, sex, ancestry, and assigned to body weight (BW) blocks. Within BW blocks, sex ratios were constant in each pen. Pen was the experimental unit and growth performance was analyzed using BW, ADG, ADFI, and G:F. There were 7 pigs/pen and 6 pens/treatment. Treatments were: 1) a negative diet (NC); 2) positive control (PC; Carbadox, 55 ppm); 3) NC+300 ppm Cordyceps mushroom powder (NC+MP); 4) PC +300 ppm mushroom(PC+MP); 5) supplemental copper sulfate (125 ppm) and zinc oxide (3000 ppm d 0-7, 2000 ppm d 7-35), CuZn. Dietary treatments were fed in a four-phase feeding program (d0-7, d7-14, d14-21, and d21-33). There were no interactions between MP and Carbadox at any time point (P > 0.10). Pigs fed the PC, PC+MP and CuZn treatment had increased BW (P < 0.05), ADG (P < 0.05), ADFI (P < 0.10) and G:F (P < 0.05) over the NC at the end of phases 1, 2, and 3, with no main effect of MP treatment. During Phase 4, pigs fed MP, PC, and CuZn diets all had increased ADG (P < 0.05; 431, 477, 455, 505, 486 g/d, diet 1-5, respectively) and ADFI (P < 0.05) over the NC fed pigs. Overall, d0-33, PC diets and CuZn supplemented pigs had increased ADG (P < 0.05) and ADFI (P < 0.05), with pigs fed MP tending to have increased ADFI (P < 0.08) over NC fed pigs. Feeding nursery pigs pharmacological levels of Cu+Zn and carbadox have economical value to increase nursery pig performance with MP may increase pig ADFI and final BW through potentially complimentary modes of action.

Abstract A total of 350 pigs (DNA 400×200, initial BW=6.3 kg) were used in a 34-d growth trial to evaluate the effects of a medium chain fatty acid (MCFA)-based feed additive in nursery pig diets. Following arrival to the nursery facility, pigs were randomized to pens (5 pigs per pen) and allowed a 4-d acclimation period. Thereafter, pens of pigs were blocked by BW and randomized to 1 of 5 dietary treatments (14 pens per treatment). Treatments were a dose response of 0, 0.5, 1.0, or 2.0% MCFA-based additive (CaptiSURE, Kemin Industries, Inc.; Des Moines, IA) as well as a treatment including 1.0% MCFA from a 1:1:1 blend of C6, C8, and C10 (Sigma Aldrich, St. Louis, MO). Treatment diets were formulated and manufactured in two dietary phases (d 0 to 13 and 13 to 34). Data were analyzed as a randomized complete block design with pen serving as the experimental unit. Overall (d 0 to 34), increasing CaptiSURE increased (linear, P ≤ 0.014) ADG and ADFI. Feed efficiency improved (quadratic, P = 0.002) with increasing CaptiSURE up to 1% of the diet with no benefit thereafter. As a result of the linear improvement in ADG, pigs fed 2.0% CaptiSURE were 1.8 kg heavier (P = 0.05) than pigs fed diets without MCFA at d 34. There was no evidence for differences between pigs fed 1.0% CaptiSURE and pigs fed the 1.0% MCFA blend of C6, C8, and C10 in phase 1, phase 2 or in overall performance. In summary, the addition of up to 2% of this MCFA-based additive in nursery pig diets resulted in linear improvements in ADG and ADFI. The MCFA-based feed additive also resulted in a similar improvement in growth performance as the C6, C8, and C10 MCFA blend when both were added at 1% of the diet.

Porcine Epidemic Diarrhea

Abstract An experiment was conducted to evaluate the effect of dietary medium-chain fatty acid (MCFA) addition on nursery pig growth performance, fecal microbial composition, and mitigation of porcine epidemic diarrhea virus (PEDV) following storage. A total of 360 pigs (DNA 400 × 200, Columbus, NE; initially 6.7 ± 0.07 kg) were randomized to pens (5 pigs per pen) on the day of weaning (approximately 20 d of age), allowed a 6-d acclimation, blocked by BW, and randomized to dietary treatment (9 pens per treatment). All MCFA (Sigma–Aldrich, St. Louis, MO) were guaranteed ≥98% purity, including hexanoic (C6:0), octanoic (C8:0), and decanoic (C10:0) acids. Treatment diets were formulated in 2 phases (7 to 11 and 11 to 23 kg BW) and formulated to meet or exceed NRC requirement estimates. Treatments (n = 8) were a dose response including 0%, 0.25%, 0.5%, 1.0%, and 1.5% added MCFA blend (1:1:1 ratio C6:0, C8:0, and C10:0), as well as treatments with individual additions of 0.5% C6:0, C8:0, or C10:0. Fecal samples were collected from pigs fed control and 1.5% MCFA blend diets on days 0 and 14 and analyzed using 16s rDNA sequencing. Following feed manufacture, feed was stored in bags at barn temperature and humidity for 40 d before laboratory inoculation with PEDV. Subsamples of retained feed were inoculated with PEDV to achieve a titer of 104 TCID50/g and separate sample bottles were analyzed on 0 and 3 d post-inoculation (dpi). Overall, ADG and ADFI were increased (linear, P ≤ 0.010) and feed efficiency (G:F) improved (linear, P = 0.004) with increasing MCFA blend. Pigs fed 0.5% C8:0 had greater (P = 0.038) ADG compared with pigs fed the control diet, and G:F was improved (P ≤ 0.024) when pigs were fed 0.5% C6:0, 0.5% C8:0, or 0.5% C10:0 compared with control. An inclusion level × day interaction was observed (quadratic, P = 0.023), where PEDV Ct values increased (quadratic, P = 0.001) on 0 dpi with increasing levels of MCFA blend inclusion and also increased on 3 dpi (linear, P &lt; 0.001). Fecal microbial diversity and composition were similar between control and 1.5% MCFA blend. In summary, the use of MCFA in nursery pig diets improves growth performance, provides residual mitigation activity against PEDV, and does not significantly alter fecal microbial composition.

Abstract A total of 710 pigs (Line 400 × 200, DNA, Columbus, net energy (NE)) were used in two experiments (Exp. 1: initially, 6.3 ± 0.05 kg; Exp. 2: initially, 6.8 ± 0.05 kg) to evaluate the effects of two medium-chain fatty acid (MCFA) based products on nursery pig growth performance. Following their arrival at the nursery facility, pigs were randomized to pens (five pigs per pen) and allowed a 4-d acclimation period. Thereafter, pens of pigs were blocked by initial weight and randomized to dietary treatment. In Exp. 1, the dietary treatments were a dose titration of: 0%, 0.5%, 1.0%, or 2.0% MCFA-based additive, as well as a diet including 1.0% MCFA from a 1:1:1 blend of C6:0, C8:0, and C10:0. In Exp.2, dietary treatments consisted of a basal diet containing no MCFA (control), the control diet with a 1.0% inclusion of four different blends of MCFA, lactic acid, and monolaurin or a diet with 1.0% added MCFA (a 1:1:1 blend of C6:0, C8:0, and C10:0). The four blends consisted of 50% C6:0, 20% lactic acid, and increasing levels of monolaurin (0%, 10%, 20%, and 30%) at the expense of C12:0 (30%, 20%, 10%, and 0%). Treatment diets were formulated and manufactured in two dietary phases. Data were analyzed as a randomized complete block design with pen as the experimental unit. In Exp. 1, overall (days 0–34), increasing CaptiSURE increased (linear, P ≤ 0.014) average daily gain (ADG) and average daily feed intake (ADFI). Feed efficiency improved (quadratic, P = 0.002) with increasing CaptiSURE up to 1.0% of the diet with no benefit thereafter. There was no evidence for differences between pigs fed 1.0% CaptiSURE and pigs fed the 1.0% MCFA blend of C6:0, C8:0, and C10:0. In Exp. 2, overall (days 0–35), pigs fed the 1.0% 1:1:1 MCFA blend had increased (P &lt; 0.034) ADFI and ADG resulting in 0.9 kg greater final weight (P = 0.014) compared with the control group. There was no evidence that the mean performance of pigs fed the four blends of MCFA, lactic acid, and monolaurin were different from the pigs fed the control diet. In summary, the addition of a 1.0% 1:1:1 blend of C6:0, C8:0, and C10:0 in nursery pig diets improved ADG, ADFI, and gain to feed ratio (G:F) compared with pigs fed the control diet. In addition, providing nursery pigs with the MCFA product CaptiSURE, up to 2% of the diet, resulted in linear improvements in ADG and ADFI. Altering the C12:0 to monolaurin ratio and adding lactic acid did not improve growth performance compared with pigs fed the control diet.

Abstract Trials suggest short and medium chain fatty acids can be used as alternatives for ZnO; however, US studies are limited. Therefore, the objective of this study was to evaluate the effects of a short and medium chain fatty acid product (Monomix, Quality Technology International, Inc., Elgin, IL) added alone or in combination with pharmacological levels of ZnO on nursery pig performance. A total of 354 pigs (DNA 200×400, initial BW=5.9 kg) were randomized to pens (5 pigs/pen) and pens were allotted to 1 of 4 treatments with 18 replicates/treatment. Treatments were arranged in a 2×2 factorial with main effects of added ZnO (0 vs. 3,000/2,000/0 ppm of Zn in phases 1, 2, and 3 respectively) and Monomix (0 vs. 0.4% in phases 1, 2, and 3). Treatment diets were formulated in three phases fed from d 0 to 7, 7 to 18, and 18 to 35 post-weaning with all diets containing 110 ppm Zn from the trace mineral premix. Data were analyzed as completely randomized design using the PROC GLIMMIX procedure of SAS with pen as the experimental unit. No ZnO × Monomix interactions (P=0.399) were observed. Feeding Monomix decreased ADFI (P=0.002) and ADG (P=0.012) from d 0 to 7, resulting in decreased d 7 BW (P=0.015) but there was no evidence for other differences. Feeding ZnO from d 0 to 7 and 7 to 18,increased ADG (P&lt; 0.001), ADFI, and BW, and improved G:F. Overall from d 0 to 35, pigs fed diets with added ZnO in phases 1 and 2 had increased (P&lt; 0.05) ADG, ADFI, and d 35 BW, with no evidence for differences in performance in pigs fed diets with Monomix. The addition of Monomix failed to improve pig performance, whereas pharmacological levels of ZnO improved ADG and ADFI.
