This study was conducted to investigate the effects of dietary supplementation with different organic acid (<b>OA</b>) mixtures on growth performance, nutrient digestibility, and gut morphology in weaned pigs. A total of 56 weaned pigs (7.93 ± 1.04 kg body weight) were assigned to four dietary treatments with seven replicates per treatment for a 35-d study conducted over two phases; phase 1 (d 1 to 14) and phase 2 (d 14 to 35). Diets consisted of 1) a corn-soybean meal-basal diet without any additive (negative control, <b>NC</b>); 2) NC + formic and propionic acids (<b>TRT1</b>); 3) NC + butyric, formic, and propionic acids (<b>TRT2</b>); and 4) NC + antibiotic (positive control, <b>PC</b>). During the overall period, the gain to feed ratio of pigs fed the PC and TRT1 diets tended to be higher (<i>P</i> = 0.059) than that of the NC diet. However, OA supplementation had no effects on nutrient digestibility. Jejunal villus height to crypt depth ratio was higher (<i>P</i> < 0.05) in pigs fed the TRT1 diet than those fed the NC diet. In conclusion, dietary OA supplementation tended to increase overall feed efficiency and improved gut morphology in weaned pigs.

Abstract This study was conducted to investigate the effects of dietary supplementation with different organic acid (OA) mixtures on growth performance, nutrient digestibility, and gut health in weaned pigs. A total of 56 weaned pigs (7.93 ± 1.04 kg BW) were assigned to 4 dietary treatments in a randomized complete block design with 7 replicates per treatment for a 35-d study conducted over two phases; phase 1 (d 1 to 14) and phase 2 (d 14 to 35). Each pen had two pigs balanced for sex. Diets consisted of 1) a corn-soybean meal-basal without any additive (negative control, NC); 2) NC + formic and propionic acids (TRT1); 3) NC + butyric, formic, and propionic acids (TRT2); and 4) NC + antibiotic (positive control, PC). Individual pig body weight and feed disappearance were recorded weekly. At the end of each phase, blood and feces were sampled. The female pig in each pen was euthanized on d 35 to collect digesta and intestinal tissue. Data were analyzed using the PROC MIXED of SAS. During the overall period, ADG tended to be lower (P = 0.069) in the TRT2 group than in the PC group. Diet had no effect on ADFI during the overall period, but G:F of pigs fed the PC and TRT1 diets tended to be higher (P = 0.059) than that of the NC diet. No effects of OA supplementation were observed on nutrient digestibility and blood cytokine. Jejunal villus height to crypt depth ratio was higher (P &lt; 0.05) in TRT1-fed pigs than that of NC-fed pigs. Pigs fed the TRT2 diet had a higher (P &lt; 0.05) fecal abundance of Bifidobacteria than those fed the PC diet in phase 1. In conclusion, dietary OA supplementation had positive effects on growth performance and gut health but no effect on nutrient digestibility in weaned pigs.

Abstract To evaluate the effect of bioactive peptide (P) in combination with high level of zinc (HZ) or acidifiers on growth performance, complete blood cell counts (CBC) and nutrient digestibility in nursery pigs, a total of 288 weaned pigs (PIC1050xDNA600) were stratified by initial BW within gender and allotted to 1of 7 treatments. Treatments for phase 1&2 were: 1) nutrient adequate positive control with HZ (PC), 2) nutrient deficient negative control with HZ (NC, -0.13% SID Lysine by reducing fish meal), 3) NC+0.25% peptide (0.25PZ), 4) NC+0.5% peptide (0.5PZ), 5) NC+0.25% peptide with standard zinc (0.25P), 6) NC+0.5% peptide with standard zinc (0.5P), 7) as 5 + 0.1% sodium butyrate and 0.5% benzoic acid (PSB). All pigs were fed a common low Zn diet (197 ppm) during phase 3. The whole blood was obtained from a close-to-average pen-BW pig repeatedly at weaning, and at the end of phase 2 and 3 to determine CBC. Titanium dioxide was used as an indigestible marker to determine nutrient digestibility. Data were analyzed using the Mixed procedures of SAS as a RCBD with treatment as fixed effect, and BW block as random effect. In overall phase 1&2, pigs fed PSB had similar ADG and BW when compared to pigs fed 0.25PZ and both were greater than NC pigs (Table 1). With the same inclusion rate of peptide, pigs fed a high zinc diet had greater BW and ADG than pigs fed a standard zinc diet. PSB pigs had the greatest G:F ratio and nitrogen digestibility among treatments. Increasing peptide in high zinc diets gradually decreased Neutrophil-to-lymphocyte ratio. This study indicates that the improvement in growth performance from pigs fed peptide is pharmaceutical zinc dependent and acidifiers can be an alternative to replace ZnO without affecting growth performance.

Abstract This study investigated the effects of encapsulated citral (CIT) and cinnamaldehyde (CIN) on growth performance, intestinal morphology and meat quality in broilers. A total of 320 0-day-age male broilers (Cobb 500) were allocated 32 pens with 8 pens per treatment. The treatments included: 1) Corn-wheat-SBM basal diet (negative control); 2) basal diet with 30 ppm avilamycin premix (positive control); 3) basal diet with 50 ppm encapsulated CIT and CIN (CCL); 4) basal diet with 100 ppm encapsulated CIT and CIN (CCH). There were no significant differences between treatments in growth performance (P &gt; 0.05) at each feeding stage. Additionally, birds had similar relative organ weights of heart, liver, spleen and bursa (P &gt; 0.05). The higher ratios of villus height to crypt depth (VCR; P ≤ 0.05) were detected in broilers fed either CCL or CCH, with an average being 14.67 and 15.13 in the duodenum, and 15.13 and 13.58 in the jejunum, respectively. Regarding meat quality, a higher pH value (pH = 6.21) in the breast was observed in 24-h post mortem chickens fed CCL (P ≤ 0.05). No significant differences of pH were detected in the breast in 96-h post mortem birds. The breast color (redness, yellowness, and lightness) in either 24-h or 96-h post mortem chickens was not significantly different among treatments (P &gt; 0.05). No change in purge loss (%) was observed in the breast after 48 h. The severity of white striping (WS) or woody meat (WB) was higher in the positive control (WS = 0.58; WB = 0.15) than in other treatments (P ≤ 0.05). In conclusion, dietary treatment with encapsulated CIT and CIN improved gut morphology and meat quality of broilers by increasing VCR in the small intestine and reducing the severity of WS/WB in the breast, respectively, without affecting growth performance.

Abstract The aim of this trial was to determine the optimal supplementation mealworm on growth performance, apparent total tract retention of nutrients, hematological traits, immune response, and intestinal morphology in weaned pigs. A total of 180 weaned pigs (Landrace×Yorkshire×Duroc; 6.27 ± 0.15 kg) were randomly allotted to 3 treatments and 6 replicates on the basis of initial body weight and sex. The dietary treatments included a corn-based diet supplemented with 0, 2.5, or 5 % mealworm in 2 phases (0–14 and 15–28 d). The gain to feed ratio (G:F) was higher in pigs fed 2.5% mealworm compared with 2.5% during the first phase. Overall ADG was improved in pigs fed 2.5% mealworm compared with pigs fed 5% mealworm. No improvement in overall ADFI and G:F were observed. No digestibility responses were observed by adding mealworm to the diet, but the digestibility of DM and GE were tended to be higher in pigs fed 2.5% mealworm compared with control in phase 1. The number of monocytes tended to be increased in pigs fed 5% mealworm. The concentration of plasma IgG was higher in pigs fed mealworm, however, the plasma IL-6 was tended to be decreased when mealworm was added to the diet (P = 0.052). There was no change in intestinal morphology with increasing dietary levels of mealworm. The results showed that the dietary supplementation of 2.5% mealworm had beneficial effects on growth performance and immune system, however, no effects were detected on growth performance when 5% mealworm was added to the diet.

Abstract Objective was to determine the effects of supplementing corn-soybean meal-based diets with a multi-enzyme on growth performance and apparent total tract digestibility (ATTD) of nutrients in growing pigs. A total of 276 pigs (BW = 33.99 ± 4.3 kg) were housed by sex in 45 pens of 6 or 7 pigs and fed 5 diets (9 pens/diet) in a randomized complete block design. Diets were positive control (PC); and negative control 1 (NC1) or negative control 2 (NC2) without or with multi-enzyme. The multi-enzyme used supplied at least 1,250, 860, 4,600, and 1,000 units of xylanase, β-glucanase, arabinofuranosidase and phytase per kilogram of diet, respectively. The PC was adequate in all nutrients according to NRC (2012) recommendations and had greater digestible P content than NC1 diet or NC2 diet by 0.134 percentage points. The NC1 diet had lower NE and digestible AA content than PC diet by 3%. The NC2 diet had lower NE and digestible AA content than PC diet by 5%. The diets were fed in 4 phases based on BW; Phase 1: 34–50 kg, Phase 2: 50–75 kg, Phase 3: 75–100 kg, and Phase 4: 100–120 kg. Nutrient digestibility was determined at the end of Phase 1. Overall (34–120 kg BW), pigs fed the PC and NC1 diets did not differ in ADG and ADFI. Pigs fed NC2 diet had lower (PPPP > 0.10). Supplemental multi-enzyme increased (P = 0.047) the ATTD of GE for NC2 diet. In conclusion, the NE and digestible AA and P can be lowered by ≤ 5% in multi-enzyme-supplemented diets without effects on growth performance pigs.

Effect of carbohydrases and phytase supplementation on growth performance, nutrient utilization and gut health of nursery pigs was evaluated. Pigs were blocked by body weight (BW) and sex and allocated to four treatments. Treatments were a positive control (PC), a negative control (NC) deficient in metabolizable energy (ME), crude protein (CP), Ca, and non-phytate P (nPP), NC plus Rovabio® Max AP enzyme mix, at 0.05 and 0.075 g kg−1. Apparent total tract digestibility (ATTD) was determined in faecal samples. Apparent ileal digestibility (AID) was determined in ileal digesta samples collected after euthanasia. Lower final BW and average daily gain (ADG) (P < 0.05) were observed in NC compared with PC. Enzyme at 0.05 g kg−1increased (P < 0.05) BW on d 14 and d 41, respectively, and also increased ADG. Enzyme at 0.075 g kg−1increased BW on d 14 and ADG on d 0 to d 14 (P < 0.05). Feed efficiency [gain to feed ratio (G:F)] was greater (P < 0.05) in PC than NC from d 15 to d 41 and from d 0 to d 41. No difference in G:F was observed with enzyme supplementation. Higher (P < 0.05) serum Ca and bone ash were observed in PC than NC. Enzyme increased the ATTD of Ca and P (P < 0.05) compared with NC.

Abstract This study was conducted to evaluate the effects of dietary β-glucan supplementation on growth performance, nutrient digestibility, blood profiles, and fecal characteristics in weaner pigs. A total of 140 weaner pigs [(Yorkshire × Landrace) × Duroc] with an average body weight of 6.37±1.14 kg were allotted to one of the following dietary treatments: 1) negative control (NC, basal diet); 2) positive control (PC, basal diet supplemented with 39 ppm Tiamulin); 3) basal diet supplemented with 0.1% β-glucan (G1); 4) basal diet supplemented with 0.2% β-glucan (G2). During days 22 to 42 and 1 to 42, pigs offered PC and G2 diets grew faster than those offered NC diet (P<0.05). Additionally, during the same periods, pigs fed G2 and PC diets exhibited improved gain:feed ratio compared to pigs receiving NC and G1 diets (P<0.05). Pigs fed G2 diet exhibited higher coefficient of total tract apparent digestibility of dry matter than those fed NC diet (P<0.05). There were no differences on blood profiles, fecal scores, fecal moisture, and fecal pH (P>0.05). Fecal lactic acid bacteria counts in G2 treatment were higher compared with PC and NC treatments (P<0.05). Coliform bacteria concentrations were decreased in pigs fed PC and G2 diets compared with those fed NC diet (P<0.05). In conclusion, the results of the current study indicate that dietary supplementation of 0.2% β-glucan can improve growth performance and dry matter digestibility, increase fecal lactic acid bacteria concentration but decrease fecal coliform bacteria concentration in weaner pigs.

Abstract The objective of this study was to determine the interactive effects of dietary fiber source and lipid source on growth performance and visceral organ weights of weaned pigs. Two hundred and eighty 21 days old pigs [initial body weight (BW) = 6.84 kg] were housed in 40 pens (7 pigs/pen). The pigs were fed 4 diets (10 pens/diet) in a randomized complete block design in 2 phases, Phase 1 from day 0 to 14 and Phase 2 from day 14 to 35. The diets were corn-soybean meal-based with either sugar beet pulp (SBP) or soybean hulls (SBH) as fiber source and either soybean oil (SBO) or choice white grease (CWG) as fat source in 2 × 2 factorial arrangement. The BW and feed intake were determined by phase, whereas visceral organ weights were determined on day 35. Fiber source and fat source did not interact on growth performance and organ weights relative to BW. Pigs fed CWG-containing diets had lower (P &lt; 0.05) gain to feed ratio than those fed SBO-containing diets by 7.95% during Phase 1 of feeding. Pigs fed SBP-containing diets had lower (P &lt; 0.05) gain to feed ratio than those fed SBH-containing diets by 7.94% during Phase 1 of feeding. However, pigs fed SBP-containing diets had greater (P &lt; 0.05) stomach weight, and tended to have greater (P &lt; 0.1) heart, small intestine and large intestine weights relative to BW than those fed SBO-containing diets. In conclusion, replacement of SBH with SBP in diets for weaned pigs reduced feed efficiency and increased visceral organ weights relative to BW, implying that the replacement of SBH with SBP in diets of weaned pigs increased energy expenditure in visceral organs. Inclusion of SBO (at the expense of CWG) in diets for weaned pigs can improve feed efficiency.

Low Energy Diet

A total of 90 finishing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 50.02 ± 1.78 kg were used in a 10 wk experiment. The pigs were distributed into three dietary treatments replicated six times with five pigs (two barrows and three gilts) per pen. The treatment diets were a positive control (PC; high-energy diet), a negative control (NC; low-energy diet), and an NC + 0.05% ferritin diet (TRT1). The supplementation of ferritin in a low-energy diet tended (P = 0.06) to increase the BW at week 5 compared with pigs fed low-energy diets without ferritin. At week 5 and overall period, the gain-to-feed ratio of pigs fed high-energy diets was higher (P < 0.05) compared with pigs fed low-energy diets. The pigs receiving a ferritin-supplemented diet had a comparable growth performance to pigs fed high-energy diets. At week 10, fecal Lactobacilli counts of pigs fed high-energy diets were higher (P < 0.05) compared with pigs fed low-energy diets. The supplementation of low-energy diets with ferritin resulted in comparable growth performance to pigs fed high-energy diets and had no adverse effect on digestibility and fecal gas emissions. Thus, it seems beneficial to include ferritin in low-energy diets of finishing pigs.

Abstract A study was conducted to determine the effects of supplementing corn–soybean meal-based diets with a multienzyme on growth performance, bone mineralization, apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients of growing pigs. A total of 276 pigs (body weight [BW] = 33.99 ± 4.3 kg) were housed by sex in 45 pens of 6 or 7 pigs and fed 5 diets (9 pens/diet) in a randomized complete block design. Diets were positive control (PC); and negative control 1 (NC1) or negative control 2 (NC2) without or with multienzyme. The multienzyme used supplied at least 1,800, 1,244, 6,600, and 1,000 units of xylanase, β-glucanase, arabinofuranosidase, and phytase per kilogram of diet, respectively. The PC diet was adequate in all nutrients according to NRC recommendations and had greater digestible P content than NC1 or NC2 diet by 0.134 percentage points. The PC diet had greater net energy (NE) and standardized ileal digestible amino acids (AA) content than NC1 diet by 3%, and than NC2 diet by 5%. The diets were fed in 4 phases based on BW: Phase 1: 34–50 kg; Phase 2: 50–75 kg; Phase 3: 75–100 kg; and Phase 4: 100–120 kg. Nutrient digestibility and bone mineralization were determined at the end of Phase 1. Overall (34–120 kg BW), pigs fed the PC and NC1 diets did not differ in average daily gain (ADG) and average daily feed intake. Pigs fed NC2 diet had lower (P &lt; 0.05) ADG and gain-to-feed ratio (G:F) than those fed PC diet. Pigs fed PC diet had greater (P &lt; 0.05) bone ash content and ATTD of P than those fed NC1 diet. The ATTD of GE for PC diet was greater (P &lt; 0.05) than that for NC2 diet, and tended to be greater (P &lt; 0.10) than that for NC1 diet. Multienzyme interacted (P &lt; 0.05) with negative control diet type on overall ADG and AID of GE such that multienzyme did not affect overall ADG and AID of GE for the NC1 diet, but increased (P &lt; 0.05) overall ADG and AID of GE for NC2 diet by 5.09 and 8.74%, respectively. Multienzyme did not interact with negative control diet type on overall G:F, bone ash content, AID of AA, and ATTD of nutrients. Multienzyme increased (P &lt; 0.05) overall G:F, AID of methionine, ATTD of GE and P, and tended to increase (P = 0.056) bone ash content. The ADG, bone ash content, and ATTD of GE and P for the multienzyme-supplemented diets were similar to (P &gt; 0.10) PC diet. Thus, NE and digestible AA and P can be lowered by ≤5% in multienzyme-supplemented diets without effects on growth performance and bone ash of pigs.
