Abstract The study was conducted to determine the effects of high levels of phytase on growth performance, nutrient digestibility, phytate breakdown, and expression of mucosal tight junction and nutrient transporter genes in weanling pigs. A total of 128 barrows were penned in groups of four and used in a randomized completely block design and assigned to four treatments for a 28-d study. A two-phase feeding was implemented (phase 1: day 1 to 14; phase 2: day 15 to 28). The diets differed in dietary calcium (Ca) and phosphorus (P) levels (positive control [PC]: 8.1 to 7.1 g/kg Ca and 6.5 to 6.8 g/kg P; negative control [NC]: 6.6 to 5.5 g/kg Ca and 5.6 to 5.3 g/kg P) from phase 1 to phase 2, respectively. NC diets were supplemented with phytase at 0 (NC), 1,500 (NC + 1,500), or 3,000 (NC + 3,000) phytase units (FTU)/kg. Blood was collected after fasting (day 27) or feeding (day 28) for the measurement of plasma inositol concentrations. On day 28, two pigs per pen were euthanized. Duodenal–jejunal and ileal digesta samples and feces were collected to determine inositol phosphates (InsP3-6) concentrations. Phytase supplementation increased the body weight on days 14 and 28 (P < 0.05). Average daily gain and feed efficiency compared with NC were increased by phytase with the majority of its effect in phase 1 (P < 0.05). The apparent ileal digestibility and apparent total tract digestibility of P were increased in piglets fed phytase-supplemented diets (P < 0.01) compared with NC piglets. Disappearance of InsP6 and total InsP3-6 up to the duodenum–jejunum, ileum, and in feces was increased by both phytase application rates (P < 0.01). Plasma concentrations of myo-inositol were higher (P < 0.001) in the phytase-supplemented diets than PC and NC diets, irrespective of whether pigs were fed or fasted. Expression of claudin 3 was higher in pigs fed both phytase-supplemented diets in the duodenum and jejunum compared with PC and NC. Mucin 2 expression was lower in the ileum of NC + 3,000 fed piglets compared with PC (P < 0.05), whereas expression of GLUT2 (solute carrier family 2-facilitated glucose transporter member 2) was increased (P < 0.05) by the NC + 3,000 treatment in all sections. In summary, high phytase supplementation increased the growth performance of nursery pigs. The increased expression of GLUT2 by phytase may indicate an upregulation of glucose absorption from the intestine by phytase.

A total of 160 crossbred weanling pigs [(Landrace × Yorkshire) × Duroc, 28 days old] with an initial bodyweight of 8.01 ± 0.74 kg were used in a 42-day trial (Phase 1: Days 1–14, Phase 2: Days 14–42). The experiment was conducted to evaluate the effects of the inclusion of fermented oats (FO) to a corn and soybean meal-based diet on the performance of weanling pigs fed with high nutrient-density (HD) and low nutrient-density (LD) diets. Pigs were randomly distributed into one of four dietary treatments in a 2 × 2 factorial arrangement. Two levels of nutrient density [LD = 3323 (Phase 1: 1–14 days) and 3269 kcal/kg (Phase 2: 14–42 days); HD = 3446 (Phase 1: 1–14 days) and 3325 kcal/kg (Phase 2: 14–42 days), the differences in dietary energy were based on differences in the content of fish meal, animal fat, corn and FO [0%, 5% (Phase 1) or 2.5% (Phase 2)] were used according to the bodyweight and sex of pigs [8 replicate pens per treatment with 5 pigs in a pen (3 gilts and 2 barrows)]. During the overall trial period (Days 1–42), the average daily gain and gain:feed ratio of pigs fed HD and FO diets were significantly higher (P ≤ 0.05) than those of pigs fed with LD and non-fermented oats diets respectively. On Day 14, the apparent total tract digestibility of dry matter and nitrogen of the HD groups were significantly greater (P ≤ 0.05) than those of the LD groups. The apparent total tract digestibility of energy of the FO groups was significantly greater (P ≤ 0.05) than that of the non-fermented oats diet groups during the whole experimental period. Pigs fed with FO showed higher (P ≤ 0.05) ileal Lactobacillus and lower (P ≤ 0.05) Escherichia coli counts compared with those fed with the non-fermented oats diet. In conclusion, administration of FO to a LD diet demonstrated beneficial effects on the growth performance, nutrient digestibility and ileal microorganisms balance of weanling pigs.

The present study tested the hypothesis that altering the ratio of omega-6 (n-6) to omega-3 (n-3) fatty acids (FAs) in the diet will improve growth performance, nutrient digestibility and blood parameters of weaner pigs. In total, 90 crossbred weaner pigs ((Yorkshire × Landrace) × Duroc, 28 days old), with an average bodyweight (BW) of 6.53 ± 0.71 kg were used in a 6-week experiment. Pigs were blocked on the basis of BW and sex and randomly allotted to one of three dietary treatments (5 pigs per pen (2 barrows and 3 gilts); 6 pens per treatment). Treatments consisted of plant-derived n-6 and n-3 FAs (15:1, 10:1 and 5:1). The experimental period was divided into three phases: Phase 1; 28–35 days of age, Phase 2; 36- 49 days of age and Phase 3; 50–70 days of age. Supplementation of varied n-6:n-3 FA ratios in the diet of weaned pigs showed linear increases (P < 0.05) in BW and average daily gain during Phases 1 and 2. The feed:gain ratios reduced linearly (P < 0.05) during Phase 1 and tended to reduce (P = 0.08) during Phase 2 as the ratio of n-6:n-3 FA decreased from 15:1 to 5:1. However, the overall performance of weaners was not affected by the n-6:n-3 FA ratio. Dry matter and nitrogen (N) digestibility increased linearly (P < 0.05) and energy digestibility tended (P = 0.089) to increase linearly with the reduction of n-6:n-3 FA ratio from 15:1 to 5:1 during Week 3 and, in Week 6, dry-matter digestibility increased (P < 0.05) linearly, whereas energy digestibility tended to increase with a decreasing n-6:n-3 FA ratio in the diet. The high-density lipid cholesterol showed a significant (P < 0.05) linear increase at Week 3 and a tendency to increase at Week 6, but no significant effects on other serum lipids were observed. The dietary n-6:n-3 FA ratio did not have a significant effect on white blood cell, lymphocyte, immunoglobulin G and tumour necrosis factor-α concentrations or faecal microbial counts. In conclusion, the reduction of n-6:n-3 FA ratio from 15:1 to 5:1 in the diet did not affect the overall performance of weaning pigs. However, it showed a positive effect on the growth performance of pigs during Phases 1 and 2.

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.

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 < 0.05) in TRT1-fed pigs than that of NC-fed pigs. Pigs fed the TRT2 diet had a higher (P < 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 Feed enzymes provide opportunities to enhance nutrient utilization and intestinal health of newly weaned pigs. The objective of this study was to evaluate supplemental effects of multi-enzymes in diets that are 7% deficient in SID Lys and other essential amino acids. Sixty four pigs weaned at 7.22 ± 0.04 kg BW were allotted to 2 dietary treatments with 8 replicates per treatment and 4 pigs per pen based on a completely randomized block design using sex and initial BW as blocks. Dietary treatment was the supplementation of multi-enzymes (4,000 U of xylanase, 150 U of amylase, 150 of β-glucanase, and 3,000 of U protease/kg, DuPont Animal Nutrition, UK). Pigs were fed based on 2 phases (14 and 27 days for each phase). Phase 2 diets included titanium dioxide as an indigestible external marker to calculate nutrient digestibility. Body weight and feed intake were measured at d 0, 14, and 42. From d 40 to 42, fresh fecal samples were collected from each pen and pooled by pen, weighed, freeze dried, and ground. Diet and fecal samples were used to quantify dry matter, titanium dioxide, and gross energy. Data were analyzed using the MIXED procedure of SAS. Initial BW were not different among treatments. Supplementation of multi-enzymes increased (P < 0.05) ADG (69 to 131 g/d), ADFI (134 to 181 g/d), and G:F (0.411 to 0.717) during phase 1. During phase 2, growth performance was not different among pigs. Supplementation of multi-enzyme increased (P < 0.05) apparent total tract digestibility (ATTD) of gross energy (84.5 to 89.3%). From this study, supplementation of 4,000 U of xylanase, 150 U of β-glucanase, 3,000 U of protease/kg, and 150 U amylase enhanced growth performance of pigs during the first 14 days after weaning and energy digestibility at 42 days after weaning.

Abstract The objective of this study was to evaluate the effects of dietary supplementation of coated omega-3 fatty acid (n-3 CFA) by corn cob power silica on performance of weaning pigs. A total of 200 weaned pigs [(Landrace x Yorkshire) x Duroc, average initial body weight at 6.97 ± 1.22 kg] were randomly assigned to four experimental treatments in a 6-week experiment in 3 phases as follows: CON, basal diet; 2) 0.3CFA, CON + phase 1(0.3% n-3CFA), phase 2(0.2% n-3CFA), phase 3(0.1% n-3CFA); 3) 0.6CFA, CON + phase 1(0.6% n-3CFA), phase 2(0.4% n-3CFA), phase 3(0.2% n-3CFA); 4) 0.9CFA, CON + phase 1(0.9% n-3CFA), phase 2(0.6% n-3CFA), phase 3 (0.3% n-3CFA). Each treatment had 10 replicates with 5 pigs (three gilts and two barrows) per replicate. The data were analyzed using the GLM procedure of SAS as a randomized complete block design. Pen served as the experimental unit. Linear, quadratic and cubic polynomial contrasts were used to examine effect of dietary treatment with coated n-3FA in the basal diet. Variability in the data was expressed as the standard error of means and P&lt; 0.05 was considered to statistically significant. Increasing the level of n-3CFA in the diet linearly increased ADG and G/F of pigs (Table 1). Increasing the level of n-3CFA showed a linear increment in the digestibility of DM (83.59, 84.38, 85.13, 85.89 %) whereas nitrogen digestibility (81.79, 82.38, 82.96, 83.64 %) showed a trend (linear effect, p=0.0594) at the end of experiment. The fecal lactobacillus count was increased (7.22, 7.27, 7.33, 7.35 log10cfu/g) with the increase in the supplemental level of n-3CFA (linear effect; p&lt; 0.05). However, there were no differences in the concentration of serum haptoglobin, or fecal E. coli, Clostridium and Salmonella counts despite the increase in n-3CFA levels in the diet. Supplementation of the diet with coated n-3 fatty acids positively affected growth performance and digestibility of dry matter and nitrogen, and enhanced the count of lactobacillus in weaning pigs.

Abstract This experiment evaluated the effect of dietary protease supplementation on pig’s growth performance and post-weaning diarrhea in a 43-d trial. A total of 936 weaned pigs [21 d of age, initial BW 5.87 ± 0.31 kg] were used in a 2 × 2 factorial design (2 nutritional levels × 2 protease levels). The nutritional levels corresponded to a standard feeding program and a reduced feeding program (15% lower SID Lys) and without or with protease supplementation (0.0125% inclusion). Piglets were distributed in 36 pens with 26 pigs per pen and 9 replicates per dietary treatment. Pigs received a common Phase 1 diet and experimental diets in Phase 2, 3, and 4, (0.91, 3.4, 4.5, and 24.0 kg/pig, respectively). Phytase was included at 2,500 U in Phase 2 – 4, all diets met energy and AA:Lys requirements for nursery pigs. Feed intake and body weight were determined every 2 weeks. A pen fecal score assessment was performed at d7, 10, and 14. Performance data were analyzed using the PROC MIXED procedure and fecal score data using the PROC FREQ procedure (SAS Inst., Inc., Cary, NC). No significant interactions (P &gt; 0.05) were observed between dietary treatments. From d15 to 43 and during overall experimental period, pigs fed standard diets had greater BW, ADG, and G:F (P &lt; 0.05) than pigs fed deficient diets (Table 1). On d7, pigs fed deficient diet had more (X2 &lt; 0.05) soft and watery feces, and consequently less normal feces compared to pigs fed standard diets (Figure 1). On d7, 10, and 14, pigs fed diets with protease supplementation had more (X2 &lt; 0.05) normal feces compared to control pigs. Overall, effects of dietary protease supplementation on growth performance were not expressive under the conditions of this study but protease addition benefited intestinal health of nursery pigs.

This study was conducted to evaluate the effects of lysine cell mass (LCM) as an alternative lysine source in diets for weaning pigs on growth performance, diarrhea incidence, and blood profiles. In experiment 1, a total of 200 weaning pigs, with an average body weight (BW) of 6.89 ± 1.04 kg, were allotted into one of five treatments with four replicates of 10 pigs per pen in a randomized complete block design (RCBD). The dietary treatments were composed of LCM supplementation (0, 0.25, 0.5, 0.75, or 1.0%) with partial replacement of L-lysine·HCl (0 to 0.8% for phase 1 diets and 0 to 0.07% for phase 2 diets). The BW and feed intake were recorded at the end of each phase (d 0 to 14 for phase 1, d 14 to 35 for phase 2), and diarrhea incidence was checked daily throughout the experimental period. Blood samples were taken from the jugular vein of pigs at 2 weeks and 5 weeks to determine the blood profiles of weaning pigs. In experiment 2, a total of 144 weaning pigs with an average BW of 6.44 ± 1.19 kg were allotted into one of six treatments with six replicates of four pigs per pen in RCBD. The dietary treatments were composed of LCM supplementation (0 to 3.5% for phase 1 diets and 0 to 2.2% for phase 2 diets) with replacement of L-lysine·HCl from 0 to 100%. In experiment 1, partial replacement of L-lysine·HCl with 0 to 1% LCM did not affect growth performance and diarrhea incidence of pigs. An increase in the LCM supplementation from 0 to 1% with partial replacement of L-lysine·HCl had no influence on the blood urea nitrogen concentrations, whereas it resulted in a linear decrease (p < 0.05) in the serum IgG concentrations for 5 weeks. In experiment 2, increasing the dietary level of LCM with replacement of L-lysine·HCl quadratically decreased (p < 0.05) ADG and G–F ratio for phase 2 and G–F ratio for the overall period such that 100% replacement of L-lysine·HCl with LCM decreased ADG and G–F ratio of weaning pigs. An increase in the LCM supplementation with replacement of L-lysine·HCl tended to decrease linearly (p < 0.10) the diarrhea incidence of weaning pigs for the overall period and linearly decrease (p < 0.05) the serum IgG concentrations for 2 weeks. In conclusion, partial replacement of L-lysine·HCl with LCM from 0 to 1% had no negative impacts on the growth performance, but 100% replacement of L-lysine·HCl with LCM decreased the growth performance of weaning pigs. Therefore, LCM could be included in the diets for weaning pigs up to 2.8% and 1.76% for phase 1 and phase 2, respectively, as a substitute for L-lysine·HCl without detrimental effects on the performance of weaning pigs.

This experiment was performed to examine the hypothesis that blood plasma (BP) with yeast (Saccharomyces cerevisiae) supplement in the diet of weaning pigs could provoke the growth performance, nutrient digestibility, fecal microbial, and reduce harmful gas excretion. A total of one hundred and eighty healthy piglets were taken and assigned (complete random blocks) to three dietary treatments as: Phase 1: Treatment (TRT) 1-6% BP; TRT 2-3% BP + 3% yeast; TRT 3-6% yeast. Phase 2: TRT 1-3%; BP., TRT 2-1.5% BP + 1.5% yeast; TRT 3- 3% yeast. Phase 3: TRT 1- Control (CON) (Basal diet); TRT 2- CON; TRT 3- CON for six- weeks. Each treatment had twelve replicates and five (three gilts and two barrows) pigs per pen. Dietary inclusion of BP with yeast supplementation significantly increased the body weight of piglets during phase 2 (p = 0.003) and phase 3 (p = 0.032). In addition, TRT2 group piglets had a significant improvement in average daily gain at the end of each phase and overall (p = 0.047, 0.025, 0.018 and 0.012, respectively). At phase 3, TRT2 group piglets showed a significant improvement on nutrient digestibility of dry matter (p = 0.012) and nitrogen (p = 0.040). The fecal microbiota of TRT2 group piglets showed a tendency to increase the number of Lactobacillus counts at phase 1 (p = 0.07) and phase 2 (p = 0.06) as well as, a significant improvement at phase 3 (p = 0.021). In addition, TRT2 group piglets had trend to decrease NH3 (p = 0.074) and H2S (p = 0.069) during phase 2, and significantly reduced NH3 (p = 0.038) and H2S (p = 0.046) at phase 3. However, the fecal score of piglets remains unaffected during the entire trial. At the end of phase 1 piglets’ IgG (p = 0.008) was significantly increased with the inclusion of BP with yeast supplementation. Based on the positive effects on body weight, average daily gain, nutrient digestibility, Lactobacillus count, and reduced gas emission, we suggest that dietary supplement with BP and yeast in the diet of weaned piglet could serve as an excellent alternative to antibiotics growth promoters.

Abstract BACKGROUND: A total of one hundred and forty, 28 d-old weaner pigs [Duroc x (Yorkshire x Landrace)] with initial body weight (BW) of 6.56±1.25kg were used in a six-week treatment (7 replicate pens per treatment; barrows, and 2 gilts/pen) to evaluate the effect of low nutrient density diet supplement with probiotic mixture supplementation on the growth performance, nutrient digestibility, fecal microbial, and gas emission of weaner pigs. RESULTS: Pigs fed low-density diet with probiotic mixture supplementation had linearly increased (P = 0.028, 0.014) the body weight (BW) at weeks 3, and 6. Moreover, average daily gain (ADG) was linearly improved (P=0.018, 0.014, 0.014) at week 3, 6, and overall experiment. However, there were no interactive effects found on the nutrient digestibility of dry matter (DM), nitrogen (N) and energy (E) throughout the experiment. Dietary inclusion of low-density diet with probiotic mixture supplementation has improved the fecal lactobacillus counts linearly, but E. coli was unaffected during the trail. On day 42, Ammonium gas emission was significantly decrease in pigs fed a low-density diet with probiotic mixture supplementation. However, H2S, acetic acid, and CO2 were not significantly affected by the probiotic mixture supplementation diet. CONCLUSION: Low-density diet with probiotic mixture supplementation had positively affected the growth performance, fecal microbial, and fecal gas emission on weaner pigs.
