Abstract Two experiments were conducted to compare the standardized ileal digestibility (SID) of AA by growing pigs in European distillers dried grains with solubles (DDGS) produced from wheat, maize, or wheat–maize mixtures and to test the effect of increasing the inclusion levels of wheat DDGS on growth performance of growing-finishing pigs fed diets balanced for NE and SID Lys. In Exp. 1, 12 barrows (initial BW: 23.0 ± 2.2 kg) were surgically equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 6 × 6 Latin square design with six diets and six periods. Five sources of European DDGS were used: wheat DDGS from 2011, wheat DDGS from 2012, wheat-80 DDGS (80% wheat and 20% maize), wheat-70 DDGS (70% wheat and 30% maize), and maize DDGS. Each diet contained one source of DDGS as the sole source of AA and an N-free diet was used to determine basal endogenous losses of AA. Results indicated that the SID of CP was greater (P < 0.05) in maize DDGS compared with wheat DDGS from 2011, wheat DDGS from 2012, and wheat-70 DDGS. The SID of all indispensable AA except Trp was also greater (P < 0.05) in maize DDGS compared with all other DDGS sources used in this experiment. For Trp, the SID in wheat-80 DDGS, wheat DDGS from 2011, and wheat DDGS from 2012 were not different from maize DDGS, but were greater (P < 0.05) than in wheat-70 DDGS. The SID for all indispensable AA except Ile and Trp in wheat-70 DDGS were not different from the values calculated for wheat DDGS from 2011 and wheat DDGS from 2012, and no differences between SID values for AA in wheat DDGS from 2011 and wheat DDGS from 2012 were observed. In Exp. 2, 36 growing pigs (initial BW: 38.3 ± 1.97 kg) were randomly allotted to one of four dietary treatments (one pig/pen and nine replicate pigs/treatment) in a 2-phase feeding program (35 to 65, and 35 to 105 kg BW). The four dietary treatments included diets containing 0%, 10%, 20%, or 30% wheat DDGS. Results indicated that there was no effect of wheat DDGS on pig growth performance or carcass quality. However, addition of wheat DDGS increased linearly (P < 0.015) the indole concentration in the carcasses of the pigs. In conclusion, the SID of AA in maize DDGS produced in Europe is greater than in European wheat DDGS and DDGS produced from mixtures of wheat and maize, but inclusion of 30% wheat DDGS in diets fed to growing-finishing pigs did not affect growth performance or carcass quality.

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.

Abstract Digestibility of AA in feed ingredients for pigs has been generally determined by feeding semipurified diets containing test ingredients as a sole source of nitrogen. However, malnutrition caused by feeding semi-purified diets may affect the digestibility of AA. Therefore, the hypothesis of this study was that the standardized ileal digestibility (SID) of AA in distillers’ dried grains with solubles (DDGS) are not affected by the addition of casein in experimental diets. In Exp. 1, 20 growing pigs were allotted to dietary treatments including 2 diets containing either 480 g/kg DDGS or 308 g/kg DDGS and 60 g/kg casein. The SID of Lys and Phe for DDGS in the diet containing casein were greater (P < 0.05) than those without casein. Exp. 2 was conducted with 20 growing pigs assigned to dietary treatments containing 0, 55, 110, or 165 g/kg casein while the concentration of DDGS decreased at 466.8, 311.2, 155.6, or 0 g/kg. The SID of most indispensable AA in DDGS linearly (P < 0.05) decreased with increasing concentration of casein. Experiment 3 was conducted to verify that the results of Exp. 1 were affected by the addition of casein or by the concentration of DDGS or both. Twenty growing pigs were assigned to dietary treatments prepared as a 2 × 2 factorial arrangement with the concentration of DDGS at 466.8 or 155.6 g/kg and casein at 0 or 110 g/kg. The SID of most indispensable AA in DDGS at 466.8 g/kg were greater (P < 0.01) than in DDGS at 155.6 g/kg regardless of dietary casein. Overall, the addition of 60 g/kg casein to experimental diets may increase the SID of AA in low-protein quality ingredients but the addition of higher concentration of casein and low concentration of dietary protein from test ingredients may decrease the SID of AA.

Abstract AbstractThree experiments were conducted to test the hypothesis that standardized ileal digestibility (SID) of amino acids (AA), concentration of metabolizable (ME), and standardized total tract digestibility (STTD) of P in a new source of distillers dried grains with solubles (DDGS; ProCap DDGS) are greater than in conventional de-oiled DDGS. In experiment 1, nine barrows (initial BW: 67.2 ± 6.4 kg) with a T-cannula in the distal ileum were allotted to a triplicated 3 × 3 Latin square design with three diets and three periods for a total of nine replicate pigs per diet. Two diets included ProCap DDGS or de-oiled DDGS as the sole source of crude protein (CP) and AA. An N-free diet was used to determine the basal endogenous losses of CP and AA. Ileal digesta were collected on days 5 and 6 of each period after 4 d of adaptation to diets. Results from experiment 1 indicated that ProCap DDGS contained more CP and AA compared with de-oiled DDGS. The SID of all AA in ProCap DDGS was greater (P &lt; 0.001) compared with de-oiled DDGS with the exception that the SID of Pro was not different between the two sources of DDGS. In experiment 2, 24 growing barrows (initial BW: 32.7 ± 3.1 kg) were housed individually in metabolism crates and used in a randomized complete block design and fed a corn-based diet or two diets containing corn and each source of DDGS with eight replicate pigs per diet. Fecal and urine samples were collected for 4 d after 7 d of adaptation. Results from experiment 2 indicated that concentration of ME in ProCap DDGS was greater (P &lt; 0.05) compared with corn or de-oiled DDGS. In experiment 3, 32 growing barrows (initial BW: 20.2 ± 0.9 kg) were placed in metabolism crates and allotted to four diets with eight pigs per diet using a 2 × 2 factorial treatment arrangement. The de-oiled DDGS and ProCap DDGS were both included in a diet without microbial phytase and a diet with microbial phytase (500 units/kg diet). Pigs were adapted to the diets for 5 d and fecal samples were collected for 4 d. Results from experiment 3 indicated that inclusion of phytase in the diet containing ProCap DDGS increased (P &lt; 0.05) the STTD of P, but addition of phytase to the de-oiled DDGS diet did not increase STTD of P (interaction, P &lt; 0.001), but the STTD of P was greater (P &lt; 0.05) in de-oiled DDGS compared with ProCap DDGS. In conclusion, ProCap DDGS has greater SID of AA and contains more ME, but has reduced STTD of P compared with conventional de-oiled DDGS.

Abstract The objective of this experiment was to test if standardized ileal digestibility (SID) of AA in a new source of high-protein distillers dried grains with solubles (HP-DDGS) is greater than in conventional distillers dried grains with solubles (DDGS-CV). Nine barrows (initial BW: 67.2 ± 6.4 kg) with a T-cannula in the distal ileum were allotted to a triplicate 3 × 3 Latin Square design with 3 diets and 3 periods. Two diets included HP-DDGS or DDGS-CV as the sole source of CP and AA. A nitrogen-free diet was used to determine basal endogenous losses of CP and AA. The statistical model included ingredient as fixed effect and square, period, and animal as random effects. Results indicated that that HP-DDGS contained more CP and AA compared with DDGS-CV (Table 1). The SID of all AA in HP-DDGS were greater (P &lt; 0.001) compared with DDGS-CV with the exception that the SID of Pro was not different between the 2 sources of DDGS. The greater concentrations of AA and values for SID of AA in HP-DDGS indicate that this new DDGS source has a very high quality and may be a great source of digestible AA in diets fed to pigs.

An experiment was conducted to determine the standardized ileal digestibility (SID) of amino acids (AA) in distillers dried grains with solubles derived from corn (C-DDGS), sorghum (S-DDGS), and triticale (T-DDGS) fed to growing pigs. A total of 16 barrows (initial body weight = 23.1 ± 2.03 kg) surgically fitted with T-cannulas at the distal ileum were divided into 4 groups based on body weight and assigned to a quadruplicated 4 × 2 incomplete Latin Square design with 4 dietary treatments and 2 experimental periods. Three diets containing C-DDGS, S-DDGS, or T-DDGS and a nitrogen-free diet were fed in each experimental period consisting of 5-d adaptation and 2-d ileal digesta collection. Pigs fed S-DDGS had less (P < 0.05) SID of histidine, isoleucine, leucine, and methionine compared with those fed T-DDGS, which were less (P < 0.05) than the values observed from pigs fed C-DDGS. The SID of arginine, phenylalanine, threonine, and valine in C-DDGS were greater (P < 0.05) than in S-DDGS but were not different from those in T-DDGS. The SID of lysine in C-DDGS was greater (P < 0.05) than in S-DDGS and T-DDGS. In conclusion, AA in S-DDGS were less digestible than those in C-DDGS and T-DDGS.

Abstract Dry extruded-expelled soybean meal (DESBM) is an attractive feed ingredient for swine not only as a protein source but also as a good source of energy because of its high fat content. Apparent (AID) and standardized (SID) ileal amino acid (AA) digestibility in DESBM fed without or with organic acid (OA) and a multicarbohydrase (MC) supplementation to growing pigs were determined. Ten ileal-cannulated barrows (17.3 ± 0.4 kg BW) were randomly assigned to 1 of 5 dietary treatments in a replicated 5 × 4 incomplete Latin square design with 4 periods, each consisting of 5 d of adaptation and 2 d of ileal digesta collection. Four cornstarch-based diets with 44.4% DESBM as the only source of AA, without or with OA and MC supplementation, and a 5% casein-cornstarch diet were used. All diets contained 0.3% titanium dioxide. Data were analyzed using the MIXED model procedures of SAS, with the final model including OA, MC, and the interaction between OA and MC as the main effects. The SID of indispensable AA in DESBM fed to growing pigs were: Arg, 93.2%; His, 85.1%; Ile, 87.1%; Leu, 87.6%; Lys, 88.7%; Met, 87.8%; Phe, 88.4%; Thr, 81.4%; Trp, 73.6%; Val, 84.5%. OA supplementation decreased the AID and SID (P &lt; 0.05) of Arg, Ile, Asp, and Glu, and tended (P &lt; 0.10) to decrease the AID and SID of Phe, Trp, Cys, Gly, and Tyr. MC supplementation did not affect the AID and SID of AA, and no interactive effect on AA digestibility was observed between OA and MC supplementation. In conclusion, dietary supplementation of OA and MC showed no positive effects on improving AA digestibility in DESBM fed to growing pigs.

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.

Abstract The objective was to determine the influence of amino acid (AA) supplementation during the adaptation period on the ileal digestibility of crude protein and AA in corn and soybean meal (SBM). Six barrows with an initial body weight of 30.9 ± 2.6 kg fitted with a T-cannula in the distal ileum were assigned to a 6 × 6 Latin square design with 6 dietary treatments and 6 periods. Two experimental diets contained corn or SBM as the sole source of AA and an N-free diet was additionally prepared. For AA supplementation groups, an AA mixture consisted of Gly, Lys, Met, Thr, Trp, Ile, Val, His, and Phe was added to the corn diet and the N-free diet at the expense of cornstarch, and an AA mixture of Lys, Met, and Thr was added to the SBM diet. All diets contained 0.5% of chromic oxide. The 6 experimental diets were fed to the pigs for 4 and half days, and the 3 diets containing AA mixture were switched to the respective diets without AA mixture during the following 2 and half days. Ileal digesta were collected during the last 2 days. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Arg and Trp in corn (P &lt; 0.05), but did not affect that in SBM. The addition of AA mixture during the adaptation period caused increased apparent ileal digestibility of Pro and Gly regardless of feed ingredient (P &lt; 0.05), but did not affect that of other AA. All AA except Pro in corn and SBM were unaffected by the addition of AA mixture during the adaptation period. In conclusion, the addition of amino acid during the adaptation period does not affect the standardized ileal digestibility of indispensable amino acids in feed ingredients.

Diet Type

In experiment, six pigs fitted with a T-cannula at the distal ileum were fed six diets in a 6×6 Latin square design. Treatments were corn-soybean meal diet (CS), diet containing wheat by-products (WBP), and diet containing corn distillers dried grains with solubles and canola meal (DDCM) without or with xylanase (X) supplementation (CS-X, WBP-X and DDCM-X). The WBP and DDCM diets had higher AID of lipids and ADF (P < 0.05) than CS diets. A xylanase×diet interaction was observed for the AID NDF (P < 0.05) showing larger impact of xylanase in WBP than in the other diets. Using similar dietary treatments except for CS-X, growth and body composition of the sixty males (83.0 kg) at the end of the d28 growing phase showed that pig fed the CS had greater ADFI (P = 0.004) and ADG (P = 0.014) for period 0-14d but not from 15 28d. Overall performance (0-28d) showed higher ADFI (9.5%; P = 0.015) in CS but no difference was observed for ADG and G:F. These results showed that diets containing a high proportion of by-products can give equivalent performance to a CS diet and that adding xylanase for this short period had limited.

Ileal Digestibility

Abstract Heat treatment could effectively decrease the antinutritional factors in soybean during meal processing. One such progress is the combination of extrusion with expelling, which produces the dry extruded-expelled soybean meal (DESBM), and there is a great interest in exploring its utilization as a dietary ingredient for swine. Thus, eight ileal-cannulated barrows (initial BW = 30 ± 1.3 kg) were used to determine the ileal amino acid (AA) digestibility of DESBM fed to growing pigs with or without multi-carbohydrase (MC) supplementation. Pigs were randomly assigned to 1 of 4 treatments in a replicated 4 × 4 Latin square design to give eight observations per treatment. The experimental diets were formulated to contain one of the two batches of DESBM (DESBM-1 and DESBM-2) as the sole source of protein. All diets contained titanium dioxide (0.3%) as an indigestible marker to calculate nutrient digestibility. Each experimental period lasted for seven days, and ileal digesta samples were collected on d 6 and d 7. The standardized ileal digestibility (SID) of AA were calculated using published mean values to estimate ileal endogenous AA losses. Data were analyzed using the mixed model procedures of SAS, and the final model had treatment, batch, and the interaction between treatment and batch as the main effects. In general, the SID of AA in DESBM-1 and DESBM-2 were not different, such as Ile, Lys, Met, Thr, and Val, which averaged 88.97%, 89.77%, 89.08%, 84.38%, and 86.85% respectively. There were no effects of MC supplementation on AID and SID of AA digestibility in DESBM except for the AID of Trp (P &lt; 0.05). Also, there were no interaction effects of MC supplementation and batch on AA digestibility in DESBM. In conclusion, enzyme supplementation did not improve the AID and SID of AA in DESBM fed to growing pigs.
