Abstract An experiment was conducted to test the hypothesis that addition of Val, Ile, or Trp alone or in combination will reduce the negative effects of excess Leu in diets for growing pigs. A total of 288 growing pigs (28.6 ± 2.5 kg) were randomly assigned to 1 of 9 dietary treatments in a randomized complete block design. There were 2 barrows and 2 gilts in each pen and 8 replicate pens per treatment. A control diet based on corn and soybean meal and 8 diets based on corn and a high-protein corn product (48% crude protein) with 2 levels of crystalline L-Val (0 or 0.10%), L-Ile (0 or 0.10%), and L-Trp (0 or 0.05%) were formulated. The crystalline L-Val, L-Ile, and L-Trp increased standardized ileal digestible (SID) Val:Lys from 70 to 80%, SID Ile:Lys from 53 to 63%, and SID Trp:Lys from 18 to 23%, respectively. All diets were formulated to contain 1.00% SID Lys and the 8 diets containing corn protein contained 171% SID Leu:Lys. Individual pig weights were recorded at the beginning and at the conclusion of the 28-d experiment. Data were analyzed using the PROC MIXED of SAS with a pen as the experimental unit. Diet was the fixed effect and block and replicate within block were random effects. Results indicated that final body weight and average daily gain were not different between pigs fed the control diet and pigs fed the diet with Val and Trp addition, but greater (P < 0.001) than for pigs fed the diet with Val addition, Ile addition, Trp addition, Val and Ile addition, Ile and Trp addition, or Val, Ile, and Trp addition (Table 1). In conclusion, addition of Val and Trp to diets with excess Leu may prevent negative effects of excess Leu in diets for growing pigs.

Abstract Our objective was to evaluate the effects of different vitamin concentrations on growth performance of wean-to-finish pigs under commercial conditions. A total of 900 barrows and gilts (PIC337×Camborough; initially 5.34±0.13 kg) were used in a 136-d growth trial with 25 pigs per pen and 12 pens per treatment in a randomized complete block design. Experimental diets were fed in 3 phases during nursery (5-6, 6-13, and 13-26 kg) and 5 phases during grow-finish (26-44, 44-65, 65-87, 87-108, and 108-128 kg). Dietary treatments consisted of: 1) NRC: vitamin concentrations following NRC (2012) recommendations; 2) PIC: vitamin concentrations following PIC (2016) recommendations; 3) Low-PIC: vitamin concentrations that ranged from 0 to 91% of PIC recommendations. Data were analyzed using the GLIMMIX procedure of SAS with pen as the experimental unit. During the nursery period, pigs fed PIC and Low-PIC diets had greater (P< 0.05) average daily feed intake (ADFI) compared to pigs fed NRC diets. There was no evidence (P >0.10) for differences in average daily gain (ADG) and feed efficiency (G:F). During the grow-finish period, there was no evidence (P >0.10) for differences in growth performance. During the overall wean-to-finish period, pigs fed PIC diets had lower (P< 0.05) ADG and final body weight compared to pigs fed NRC and Low-PIC diets. There was no evidence (P >0.10) for differences in ADFI or G:F. Pigs fed PIC diets had the greatest serum vitamin D3 at the end of nursery and finish periods (P< 0.05) and the greatest serum Vitamin E at the end of nursery period (P< 0.05). In summary, pigs fed PIC and Low-PIC diets had greater nursery feed intake and serum vitamin E and D3 concentrations compared to pigs fed NRC diets. Data from this study have demonstrated that pigs fed diets with reduced vitamin concentrations compared to PIC (2016) recommendations had improved wean-to-finish growth rate.

Abstract Two hundred and forty sows (Camborough, PIC, Hendersonville, TN) were started on study at 35 d post-breeding through lactation to determine the effects of soluble concentrated yeast product (Celmanax SCP, Arm and Hammer, Princeton, NJ) on sow and litter performance. Sows were fed their respective dietary treatments: 1) Control diet gestation x control diet lactation; 2) 0.01% Celmanax SCP in gestation x control diet lactation; 3) Control diet gestation x 0.02% Celmanax SCP in lactation; and 4) 0.01% Celmanax SCP in gestation x 0.02% Celmanax SCP in lactation. All diets were formulated to meet or exceed NRC (2012) requirements and contained a feed disinfectant. Sows were allowed ad libitum access to feed and water in lactation. Litters were weighed after cross-fostering, 48 h post-farrow (after litter adjustments and cross-fostering) and at weaning. Sows were weighed entering farrowing and at weaning. Data were analyzed as a randomized complete parity block using PROC MIXED of SAS with sow as the experimental unit, treatment as a fixed effect, and parity as a random effect. There were detectable levels of fumonisin (2 ppm), vomitoxin (1.3 ppm) and zearalenone (243 ppb). There were no differences in sow feed intake or body weight loss (P > 0.10). There was a significant difference in treatments 1, 2, 3 and 4 for days between wean to estrus (5.99, 5.12, 4.90, 4.49; P = 0.01) and percent bred within 7 d (86.53, 97.06, 97.85, 100.00; P = 0.01), respectively. Average piglet wean weights (kg) were 5.82, 5.87, 5.93, 6.01; P = 0.02 for treatments 1, 2, 3 and 4 respectively. Furthermore, there were no responses in piglet average daily gain or mortality (P > 0.10). The feeding of the soluble yeast product to sows does appear to improve subsequent breeding and litter performance.

Standardized Ileal Digestible Lysine

Abstract Our objective was to determine the effects of feeding different neutral detergent fiber (NDF) and standardized ileal digestible (SID) lysine (Lys) levels on performance of growing-finishing pigs from 30- to 130-kg. A total of 2,016 barrows and gilts (PIC 280×Camborough, initial BW of 29.6±0.53 kg) were allotted to a randomized complete block design with a 2×2 factorial arrangement. Dietary treatments (Table 1) consisted with two NDF levels (13% or 20%) and two SID Lys curves (PIC2008 or PIC2016). There were 21 mixed-sex pigs per pen, and 24 pens per treatment. The experiment diets were fed in 3 phases. Wheat, wheat by-products, peas, and canola oil were used with NRC (2012) loading values to achieve treatments, and all diets were formulated to be iso-caloric (2,420 kcal NE/kg). Experimental data were analyzed using generalized linear mixed models with pen as the experimental unit. Increasing NDF level resulted in a reduction (P< 0.05) in average daily gain (ADG), average daily feed intake, hot carcass weight, carcass yield, carcass ADG, and backfat depth (Table 2), and tended to decrease percentage of removals and mortality (P=0.10). Pigs fed PIC2016 Lys curve had greater ADG and carcass ADG as compared to those fed PIC2008 Lys curve (P< 0.05). There were NDF×Lys interactions (P< 0.10) for ADG, gain to feed ratio (G:F), carcass ADG, and carcass G:F. These response criteria were improved for pigs fed PIC2016 Lys curve compared to those fed PIC2008 Lys curve when NDF level was 13%; while no evidence of differences was observed at 20% NDF. Results indicate that increasing NDF level from 13 to 20% deteriorate performance of 30- to 130- kg pigs; and the improved growth performance of pigs fed PIC2016 Lys curve as compared to those fed PIC2008 Lys curve was only observed when lower NDF level was presented.

Abstract Based on results of a recent meta-analysis, we hypothesized that increased dietary Val, Ile, or Trp could correct possible amino acid interactions because of excess Leu in diets containing high levels of corn protein, namely dried distiller’s grains with solubles (DDGS). A total of 1,200 pigs (PIC TR4 × (Fast LW × PIC L02); initially 33.6 ± 0.6 kg) were used in a 103-d study. The 6 dietary treatments were corn–soybean meal (SBM)-DDGS-based as follows: (1) high SBM and low level of l-Lys HCl (HSBM), (2) high l-Lys HCl and moderate Ile, Val, Trp (AA above NRC 2012 estimates; NC), (3) moderate l-Lys HCl and high Ile, Val, and Trp (PC), and PC with either increased (4) L-Val (PC+Val), (5) L-Ile (PC+Ile), or (6) L-Trp (PC+Trp). Pigs fed the NC diet were predicted to have the poorest average daily gain (ADG), the PC diet to be intermediate, and pigs fed the HSBM, PC+Val, PC+Ile, and PC+Trp have the same and highest predicted ADG. In the grower period (34 to 90 kg), ADG was greater (Ρ < 0.05) for the pigs fed HSBM and PC+Val diets than the NC with pigs fed other diets intermediate. Pigs fed HSBM were more (Ρ < 0.05) efficient (G:F) than the NC and PC with pigs fed other diets intermediate. In the finisher period (90 to 136 kg), ADG was greater (Ρ < 0.05) for pigs fed PC+Ile than that of the NC with pigs fed other diets intermediate. Pigs fed PC+Val had greater (Ρ < 0.05) average daily feed intake (ADFI) than the NC with pigs fed other diets intermediate. However, PC+Ile pigs were more (Ρ < 0.05) efficient than PC+Val with pigs fed other diets intermediate. Overall, ADG was greater (Ρ < 0.05) for pigs fed HSBM, PC+Val, and PC+Ile diets than the NC with pigs fed other diets intermediate. Pigs fed the PC+Val diet had greater (Ρ < 0.05) ADFI than the NC with pigs fed other diets intermediate. No differences were detected between treatments for overall G:F or other carcass characteristics. In conclusion, increasing Val or Ile in high l-Lys-HCl-DDGS-based diets improved growth performance compared with pigs fed diets containing high levels of l-Lys HCl without added Val and Ile. These results present evidence that the recently developed meta-analysis can predict the relative differences in overall ADG for pigs fed the NC, PC, PC+Val, and PC+Ile diets; however, the predicted G:F was less accurate. The data demonstrate that the negative effects of high Leu concentrations in corn-DDGS-based diets can be reversed by increasing the ratios of Val and Ile relative to Lys.

Abstract Based on a recent meta-analysis, we hypothesized that increased dietary Val, Ile, or Trp could correct possible amino acid interactions caused by high dietary Leu in diets containing high levels of corn protein, namely dried distillers grains with solubles (DDGS). A total of 1,200 pigs (PIC TR4×(Fast LW×PIC L02); initially 33.6±0.63 kg) were used in a 103-d study. The 6 dietary treatments were corn-soybean meal-DDGS-based diets as follow: low level of Lys-HCl (SBM), high Lys-HCl and moderate Ile, Val, Trp (NC; AA above NRC 2012 estimates), moderate Lys-HCl and high Ile, Val, Trp (PC), and PC with either increased L-Val (Val), L-Ile (Ile), or L-Trp (Trp). Diets contained 30% DDGS until pigs reached approximately 100 kg and then 20% DDGS until market. Data were analyzed as a randomized complete block design using lmer function in lme4 package in R with pen considered as the experimental unit, body weight as blocking factor, and treatment as a fixed effect with 10 replicates/treatment. Overall final BW and ADG were greater for pigs fed SBM, Val, and Ile diets than the NC with PC and Trp intermediate. Pigs fed the Val diet had greater (R< 0.05) ADFI than the NC with pigs fed SBM, PC, Ile, and Trp intermediate. No differences were detected between treatments for G:F. In conclusion, increasing Val or Ile in high Lys-HCl-DDGS-based diets improved growth performance and final BW compared with pigs fed diets containing high levels of HCl-Lys without added Val and Ile. These results demonstrate that negative effects of high Leu in corn-DDGS-based diets can be overcome by increasing the ratios of Val and Ile to Lys.

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 An experiment was conducted to test the hypothesis that feed flavor and feed sweetener improve growth performance of weanling pigs. One hundred twenty-eight pigs (5.97 ± 0.55 kg) were allotted to 4 treatments with 4 pigs per pen and 8 pen replicates per diet. A 3-phase feeding program was used. In all phases, a control diet was formulated based on corn and soybean meal, and 3 additional diets were formulated by adding feed flavor (500 mg/kg), feed sweetener (150 mg/kg), or their combination to the control diet. Fecal scores were visually assessed using a score from 1 to 5 (1 = normal feces to 5 = watery diarrhea). Experimental diets were fed to pigs for 6 wk. Data were analyzed using SAS with pen as the experimental unit. Diet was the fixed effect and replicate was the random effect. Results indicated that overall average daily feed intake (ADFI) was greater (P &lt; 0.05) and overall average daily gain (ADG) tended to be greater (P &lt; 0.10) for pigs fed the diet containing feed sweetener compared with pigs fed the control diet (Table 1). The observed improvements in ADG and ADFI also resulted in greater (P &lt; 0.05) final body weight for pigs fed the feed sweetener diet compared with pigs fed the control diet. Inclusion of feed flavor, feed sweetener, or the combination of feed flavor and sweetener in diets did not affect fecal scores of pigs, but inclusion of feed flavor resulted in reduced overall frequency of diarrhea (P = 0.05). In conclusion, supplementation of feed sweetener improved growth performance and feed flavor supplementation to diets ameliorated post-weaning diarrhea of weanling pigs from d 1 to 42.

Abstract An experiment was conducted to evaluate the effects of increasing the inclusion of proso millet on the growth performance of growing and finishing pigs. Using a randomized complete block design, 36 crossbred barrows, with an average initial weight of 22.2 kg, were randomly assigned to 1 of 4 dietary treatments (9 pens/treatment; 1 pig/pen). Diet 1 was corn-soybean meal-based (control) and Diets 2, 3, and 4 had proso millet replacing 33%, 67%, and 100%, respectively, of corn in the control diet. The diets were formulated according to 4 growth phases (P1, 25 to 50 kg BW; P2, 50 to 75 kg BW; P3, 75 to 100 kg BW; and P4, 100 to 135 kg BW) with nutrient contents formulated according to NRC (2012) recommendations. Data were analyzed using the GLIMMIX procedure of SAS, using pig as the experimental unit. In P1 and P2, no differences in average daily gain (ADG) or average daily feed intake (ADFI) were observed among treatments (P &gt; 0.3). In P3, pigs consuming the proso millet diets had greater ADFI than pigs consuming the basal diet, especially pigs fed Diet 4 compared to pigs fed Diet 1 (3.66 vs. 3.29 kg; P &lt; 0.01). The ADG:ADFI ratio was not affected (P &gt; 0.1) by treatments during this period. In P4, although there was a difference in ADFI between pigs fed Diet 3 and Diet 1 (3.8 vs. 3.47 kg; P = 0.04), no decreases in ADG:ADFI ratio were observed among the four dietary treatments (P &gt; 0.5). Average daily gain was not affected (P &gt; 0.3) by treatments during the growing-finishing period, suggesting that the level of corn replacement up to 100% by proso millet did not affect pig growth. In conclusion, proso millet was shown to effectively replace corn in corn-soybean meal-based diet for growing-finishing pigs without compromising growth performance.

Abstract An experiment was conducted to test the hypothesis that Val from a Val-containing fermentation biomass product (Val-FB; 64.4% L-Val) has a bioavailability of 100% relative to L-Val (98% Val) when fed to weanling pigs. A Val-deficient basal diet containing 0.63% standardized ileal digestible (SID) Val was formulated. Six additional diets were prepared by supplementing the basal diet with 0.08, 0.16, or 0.24% L-Val or 0.12, 0.25, or 0.37% Val-FB to create experimental diets containing 0.71, 0.79, or 0.87% SID Val. A total of 224 weanling pigs (6.87 ± 0.64 kg) were allotted to a randomized complete block design with 7 diets and 8 replicate pens per diet. Diets were fed for 21 d and growth performance was measured on a pen basis. Orthogonal-polynomial contrasts were used to determine linear and quadratic effects of L-Val and Val-FB levels on performance and the effect of Val sources. A linear regression model based on performance was used to estimate the relative bioavailability (RBV) of Val in Val-FB relative to L-Val. The final body-weight (BW) and average-daily-gain (ADG) were greater (P < 0.01) for pigs fed diets supplemented with Val-FB than pigs fed diets supplemented with L-Val (Table 1). The average-daily-feed-intake (ADFI) decreased linearly (P < 0.01), whereas gain-to-feed ratio (G:F) increased (P < 0.01) by supplementing graded levels of both Val sources to the diets. The RBV of Val in Val-FB as determined by ADG, G:F, and final BW was 146, 135, and 143%, respectively, with 95% confidence intervals of 99 to 191%, 83 to 187%, and 70 to 217%, respectively. In conclusion, the linear regression estimated a RBV of at least 100% for Val-FB relative to L-Val, and pigs fed diets supplemented with Val-FB had greater ADG and final BW than pigs fed diets supplemented with the same amount of L-Val.

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
