The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.

This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

The aim of this study was to assess the effects of dietary probiotic enhanced liquid acidifier combined with mannan-rich fraction on growth performance, nutrients digestibility in growing pigs. Thirty [(Duroc×Yorkshire)×Landrace] pigs with the average initial BW of 36.75±1.57 kg were allocated into three treatments by a randomized complete block design. There were five pens per treatment with six pigs per pen. Dietary treatments include: 1) CON (basal diet); 2) T1 (basal diet+probiotic 0.1%) and 3) T2 (basal diet+probiotic+mannan rich fraction 0.2%). the data were analyzed as a randomized complete block design using of SAS University Version 4.0. The model included the effects of block (replication) and treatment. Pen served as the experimental unit. During the entire experimental period of 6 weeks, results showed that addition of complex probiotic at the level of 0.2% to diet increased ADG significantly (p<0.05). Also, digestibility of DM and N tended to increase. To sum up, results in this experiment indicated that dietary [(probiotik×acidifier)×mannan-rich-fraction]  supplementation had a positive effect on growing pigs performance and nutrient digestibility

Abstract The objective of this study was to evaluate the relative bioavailability (RBV) of l-Lys sulfate in comparison to l-Lys HCl based on the growth performance response from approximately 26 to 48 kg and from approximately 68 to 114 kg. The effect of Lys source on blood urea nitrogen (BUN), digestibility of dry matter (DM) and sulfur (S), as well as carcass characteristics was determined. A total of 280 growing pigs (25.9 ± 0.25 kg BW) were randomly assigned to one of seven dietary treatments in 56 pens, with five pigs per pen. The diets included a Lys-deficient basal diet (65% of requirement) and the basal diet supplemented with three graded levels of Lys (75%, 85%, and 95% of requirement), as either l-Lys HCl (78.8% Lys purity) or l-Lys sulfate (54.6% Lys purity). The experiment lasted for 112 d, with four dietary phases: Phase 1 lasted for 4 wk (BW: 25.9 to 47.5 kg), Phase 2 lasted for 3 wk (common commercial diet as washout period), Phase 3 lasted for 5 wk (BW: 67.5 to 98.2 kg), and Phase 4 lasted for 3 or 4 wk to reach an average market weight of 114.2 kg. Fresh fecal samples of pigs fed the highest levels of Lys (both Lys sources) were collected on 7 to 10 days after the beginning of Phase 3 for digestibility assay. Blood samples were collected on day 21 and day 81 to determine BUN. Carcass data were collected at a commercial packing plant. Data were analyzed using PROC GLM of SAS (9.4) according to a completely randomized design with pen as the experimental unit. The RBV of l-Lys sulfate was determined using the multiple regression slope-ratio method. Increasing levels of Lys, independent of source, increased (P &lt; 0.05) BW, ADG, and feed efficiency during Phases 1, 3, and 4; market BW increased linearly (P &lt; 0.01) and backfat and BUN decreased linearly (P &lt; 0.01). Lysine source had no impact on growth performance, carcass characteristics, BUN, or digestibility of S and DM. The RBV of l-Lys sulfate compared with l-Lys HCl was also not different based upon ADG or G:F during Phase 1, 3, or 4. These data suggest that the bioavailability of Lys in l-Lys sulfate and l-Lys HCl is at least equivalent for growing–finishing pigs.

Randomized Complete Block Design

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.

A ten-week experimental trial was carried out to determine the effect of - dietary inclusion of Achyranthes japonica extract (AJE) on finishing pigs overall performance. A total of 150 finishing pigs with initial body weight (BW) of 54.17 ± 2.27 kg were randomly allocated to 5 dietary treatments. The dietary treatments were CON (Basal diet), TRT1 (Basal diet + 0.025% AJE), TRT2 (Basal diet + 0.05% AJE), TRT3 (Basal diet + 0.1% AJE), TRT4 (Basal diet + 0.2% AJE). Dietary AJE supplementation linearly increased BW, average daily gain (ADG), and gain to feed ratio (G:F) during week 5. At week 10 and overall experiment, there was tendency for linear increase in BW, ADG and ADFI. Dietary supplementation of AJE failed to show significant effects on nutrient digestibility, fecal microbiota, meat quality, and fecal gas emission. The dietary supplementation of AJE showed a linear increase in the backfat thickness at week 10 and there was no significant difference observed on the lean meat percentage. In summary, Achyranthes japonica extract supplementation diet had a beneficial effect on the growth performance and backfat thickness and also no effects on nutrient digestibility and fecal microbiota of the finishing pigs.

AbstractA 2 ✕ 2 factorial arrangement of treatments used 280 growing pigs and 240 finishing pigs to examine the main effects and interactions between two levels of stocking density (0·75 m2 v. 0·45 m2 per growing pig and 0·88 m2 v. 0·53 m2 per finishing pig) and grouping (static groups v. regrouped) on pig growth performance, carcass characteristics, nutrient digestibility and measurements of physiological indicators of stress responses. Regrouping was achieved by moving four unfamiliar pigs between replicate groups every 14 days. Average daily gain (ADG) and average daily food intake (ADFI) were reduced by an additive interaction between high density and regrouping in growing pigs (P < 0·01). In finishing pigs, regrouping reduced ADG (P 0·05) and carcass weight (P 0·05). Regrouping reduced apparent dry matter and gross energy digestibility in finishing pigs (P 0·05). Rectal temperature increased 3 h after mixing finishing pigs (P 0·05), but not growing pigs. In growing pigs, the neutrophil: lymphocyte ratio tended to increase (P 0·1) after regrouping, although plasma cortisol concentration was unaffected. In finishing pigs, the response to a Newcastle disease virus antigen challenge tended to decrease at high stocking density (P 0·1), although total IgG concentration was unaffected. In conclusion, the growth performance of growing and finishing pigs was affected by social stressors. However, effects on the physiological measurements did not concur with effects on growth performance.

Abstract The present study was undertaken to determine the effects of different flavours (apple and anise) on growth performance, nutrient digestibility, blood profiles and carcass quality in growing-finishing pigs. A total of 96 pigs [(Landrace × Yorkshire) × Duroc] with an average initial BW of 28.2 ± 0.7 kg were assigned to 1 of 3 dietary treatments. The treatments consisted of (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavour; (3) ANF, basal diet + 0.05% anise flavour. There were 8 replications (pens) per treatment and 4 pigs per pen (2 barrows and 2 gilts). The flavour was added at the expense of corn (0.05%). The experiment lasted for 15 wks. The data were analyzed by ANOVA using the GLM procedure of SAS (SAS Institute Inc., Cary, NC, USA) with the pen as the experimental unit. Variability in the data was expressed as the standard error of means (SEM) and a probability level of p &lt; 0.05 was considered to be statistically significant. During week 0-5, pigs fed ANF diets had greater (p &lt; 0.05) ADG and ADFI than those fed CON and APF diets. Dietary ANF treatment increased (p &lt; 0.05) ADG during 0-15 week compared with CON treatment (Table 1). At the end of 5 week, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p &lt; 0.05) compared with that in CON treatment (Table 1). There were no differences (p &gt; 0.05) in the red blood cell and white blood cell counts or lymphocyte percentage among treatments. In conclusion, anise flavour supplementation could lead to significant improvement in ADG and N digestibility in growing pigs and the ADG was also higher in finishing pigs fed anise flavour supplemented diet. Furthermore, apple flavour supplementation had minor effect on growth performance, nutrient digestibility, blood profiles or carcass quality in finishing pigs.

Abstract The objective of this study was to evaluate the effect of dietary inclusion of narasin or zinc bacitracin on the growth performance and carcass characteristics of finishing pigs sent for slaughter using a 3-phase marketing strategy. The study used 2,219 crossbred pigs in a randomized complete block design (blocking factor = start date) with 3 dietary treatments: 1) Control (no feed additive), 2) 15 mg/kg narasin (Skycis, Elanco Animal Health, Greenfield, IN), and 3) 28 mg/kg zinc bacitracin (Albac, Zoetis, Parsippany, NJ). Pigs were housed in single-sex pens of 25 pigs in a commercial wean-to-finish facility and there were 30 pen-replicates of each dietary treatment. All pigs were weighed as a group (i.e., pen) on d 0 (start of experimental feeding period), 77, 91, and 105 (end) of study. Pigs had ad libitum access to feed and water throughout the study period; all feed additions to the feeder were recorded. Pigs were sent for slaughter according to the following marketing strategy: 1) after 77 d on study, the heaviest 20% of each pen was sent for slaughter (Phase 1), 2) after 91 d on study, the next heaviest 48% of each pen were sent for slaughter (Phase 2), and 3) after 105 d on study, the remaining 32% of each pen was sent for slaughter (Phase 3). Pigs within each pen were selected for slaughter by visual appraisal of weight and shipped to a commercial slaughter facility where standard carcass measurements (HCW, LM depth, and backfat depth) were measured. Feeding narasin increased (P &lt; 0.05) final live BW (1.3 kg) and overall ADG (1.1%) compared to the other treatments, which were similar (P &gt; 0.05). Dietary treatment did not impact (P &gt; 0.05) overall G:F. Feeding narasin increased (P &lt; 0.05) HCW (1.4 kg) and carcass yield (0.3% units) compared to the other dietary treatments, which were similar (P &gt; 0.05) for these traits. Overall, these results demonstrate that narasin-fed pigs had improved overall growth rate, HCW, and carcass yield compared to controls or pigs fed zinc bacitracin.

Abstract Two experiments were conducted to determine the effects of myo-inositol and phytase on growth performance, plasma metabolites, and nutrient digestibility of growing pigs. In experiment 1, 96 growing pigs with average initial body weight (BW) of 26.2 kg were used in a 25-d growth performance study. Pigs were assigned to four dietary treatments with three pigs per pen and eight replicate pens per treatment in a randomized complete block design. The four treatments were control diet (CD); CD + 2 g/kg inositol; CD + 1,000 FYT/kg phytase and CD + 3,000 FYT/kg phytase. Pigs were weighed individually every week. On day 25, blood sample was collected from one pig per pen to measure plasma metabolites concentrations. In experiment 2, 16 barrows (initial BW 34.8 ± 8.2 kg) were surgically fitted with T-cannulas. Pigs were allotted to four blocks based on BW and assigned to a quadruplicate 4 × 2 incomplete Latin square design with same four dietary treatments and two periods. Ileal digesta samples were collected from each pig on days 6 and 7 of each period to determine apparent ileal digestibility (AID) of nutrients. Phytase supplementation increased final BW and average daily gain (ADG) compared with CD (P < 0.05) with no effects on average daily feed intake (ADFI) and gain to feed (G:F) was higher in 3,000 FYT/kg phytase (P < 0.05). Inositol supplementation had no effects on growth performance. Plasma myo-inositol concentration was increased by inositol supplementation, and 3,000 FYT/kg phytase increased myo-inositol in the plasma by 97.2% (P < 0.05). Plasma P concentration was increased by 1,000 or 3,000 FYT/kg phytase with no effects on alkaline phosphatase (ALP), glucose, triglycerides (TAG), calcium (Ca), and urea concentrations. Phytase supplementation reduced (P < 0.05) the phytate-P concentration in the ileal digesta and increased the digestibility of phytate-P and total P with no effects on the AID of dry matter (DM), gross energy (GE), nitrogen (N), and Ca. In conclusion, the beneficial effects of 3,000 FYT/kg phytase on feed efficiency may due to the increased release of both myo-inositol and phosphorus (P), and may not be solely due to myo-inositol release by this level of phytase.

Abstract Arginine plays an important role in regulating arginine-nitric oxide synthase pathway, regulating lipid metabolism, and upregulating the mRNA levels of genes involved in fat synthesis in muscle in animals, and can therefore improve feed utilization for protein accretion. The objective of this study was to investigate the effects of supplementation of different concentrations of L-arginine on growth performance, nutrient digestibility, and meat quality in finishing pigs. A total of 120 crossbred [(Landrace × Yorkshire) × Duroc] pigs with an average initial body weight (BW) of 53.80 ± 1.86 kg were used in this 10-week feeding trial. The pigs were randomly allotted to 1 of 3 dietary treatments (5 pigs/pen and 8 replicates/treatment) in a randomized complete block design according to their sex (2 gilts and 3 barrows) and BW. Dietary treatments included: 1) CON, corn-soybean meal based basal diet (containing 13.81 MJ/kg metabolic energy and 0.95% lysine for entire experimental period); 2) LA0.5, CON + 0.5 g/kg L-arginine; 3) LA1.0, CON + 1.0 g/kg L-arginine. Individual body weight was measured initially and at the end of 5th and 10th week, feed consumption was recorded on pen basis during the experiment to determine growth performance. Meat samples were randomly taken from each pen (2 pigs per pen, 1 gilt and 1 barrow; 16 pigs per treatment) for determination of meat quality. All data were analysed using linear and quadratic contrast (SAS Institute Inc., Cary, NC, USA). The result showed that L-arginine did not affect pig growth performance and nutrient digestibility. However, dietary L-arginine supplementation linearly increased (P&lt; 0.05) muscle marbling score, while linearly decreasing (P&lt; 0.05) cooking loss and drip loss of pork muscle (Table 1). Results of present study demonstrated that 1.0 g/kg L-arginine would be beneficial in improving the meat quality in finishing pigs.
