Abstract The objective of this study was to determine the impact of reducing the mean particle size (PS) of corn distillers dried grains with solubles (DDGS) with a hammermill (HM) or with a roller mill (RM) on the apparent total tract digestibility (ATTD) of dry matter (DM), gross energy (GE), N, acid hydrolyzed ether extract (AEE), and fiber components in growing and finishing pigs. Twenty-four growing barrows were housed in individual pens and were randomly assigned to a 3 × 2 factorial design (n = 8): three grinding methods [either corn DDGS ground with an HM to a PS of 450 μm; corn DDGS ground with an RM to a PS of 450 μm; and corn DDGS with a PS of 670 μm (not further ground)] and two body weight (BW) periods (growing pigs with an average initial BW of 54.7 ± 0.9 kg, and finishing pigs with an average initial BW of 107.8 ± 1.5 kg BW). Fecal samples were collected for each BW period in the last 3 d of an 11-d feeding period. Titanium dioxide was used as an indigestible marker. Digestibility data were analyzed using the MIXED procedure of SAS. Results showed that finishing pigs tended to have better ATTD of DM than growing pigs (P = 0.09) and had increased ATTD of GE and N than growing pigs (P = 0.03 and P < 0.01, respectively). On the other hand, growing pigs had better ATTD of AEE than finishing pigs (P = 0.01). Pig BW period did not affect the ATTD of neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose. Reducing the mean PS of corn DDGS with either HM or RM (from 670 to 450 µm) improved the ATTD of DM and GE (P < 0.01 and P < 0.01), tended to improve the ATTD of N (P = 0.08), and improved the ATTD of AEE (P < 0.01). No effect of reducing PS was observed for the ATTD of NDF, ADF, or hemicellulose. There were no differences between HM and RM in any of the ATTD variables tested. In conclusion, reducing PS of corn DDGS from 670 to 450 μm either with an HM or with an RM improved the digestibility of DM, GE, and AEE and modestly improved the digestibility of N in growing and finishing pigs. However, reducing the PS of corn DDGS did not affect the digestibility of fiber components.

Diet Type

This study was conducted to determine the effect of pelleting and diet type on the apparent ileal (AID) and total tract digestibility (ATTD) of nutrients and energy in growing pigs. Six pigs were cannulated at the ileum and were assigned to treatments following a crossover design. One diet was a control diet based of corn and soybean meal (CT). Part of it was replaced by corn distillers dried grains with solubles (cDDGS), wheat middlings and bakery meal in the second diet (ByP). Diets were in mash (CT-MH and ByP-MH) or pelleted (CT-PT and ByP-PT) form. Results showed that pelleting increased digestibility in all diets with a distinct effect on the CT diet (interaction Diet x Pelleting, P < 0.05). Pelleting improved the AID of DM, CP and energy by 17, 27 and 17% in the CT diet and by 10, 9 and 17% in the ByP diet (P < 0.01). The AID of AA followed the effect observed on CP (P < 0.01). Pelleting increased AID of total NSP for the CT diet by 63% and 42% for the ByP diet (P < 0.01). The pelleting conditions improved the degradability of the compounds in the diets during digestion in pigs.

Abstract Three experiments (Exp.) were conducted to determine and compare the digestibility of nutrients and energy of corn distillers dried grains with solubles (DDGS) from the US (USDDGS), a dried mixture of corn bran with solubles (CBS) from Brazil (BRCBS), and high protein corn distillers dried grains (HP-DDG) from the US (USHPDG) and Brazil (BRHPDG) in growing pigs. The feed ingredients were evaluated for apparent total tract digestibility (ATTD) of gross energy (GE), dry matter (DM), crude protein (CP), ether extract (EE), neutral and acid detergent fiber (NDF and ADF, respectively), digestible and metabolizable energy (DE and ME, respectively) using total collection and index methods in Exp. 1; ATTD and standardized total tract digestibility (STTD) of phosphorus (P) in Exp. 2; and apparent (AID) and standardized (SID) ileal digestibilities of CP and amino acids (AA) in Exp. 3. Fifty crossbred barrows (32.4 ± 6.9 kg, 38.3 ± 5.2 kg and 46.2 ± 5.3 kg BW, in Exp. 1, 2 and 3, respectively) were fed a corn basal diet in Exp. 1, a P-free diet in Exp. 2, and a N-free diet in Exp. 3, or diets with 40% inclusion of test ingredients to provide 10 replications per treatment. Pigs were housed individually in metabolism cages (Exp. 1) or in pens (Exp. 2 and 3) and fed at 2.8 times the maintenance DE requirement (110 kcal / kg BW 0.75) based on their BW at the beginning of each experiment. Except for ATTD of NDF, which tended (P = 0.058) to be greater by index method compared to total collection method, no difference between total collection and index methods were observed for ATTD of remaining nutrients and DE. The ATTD of DM, GE, NDF and DE content of BRHPDG were greater (P &lt; 0.001) than USHPDG, BRCBS and USDDGS. The AID of CP, Arg, His, Ile, Leu, Lys, Thr and Val; and the SID of His, Leu, Lys, and Val of BRHPDG were 8 to 36% greater (P &lt; 0.05) than those from USHPDG. Except for Trp, all AID and SID AA values were greater (P &lt; 0.05) in BRHPDG than in USHPDG. The ATTD of DM, GE, NDF, and ADF; DE and ME content; AID of CP, Arg, Ileu, Leu, Phe, Thr, and Trp; and SID of CP, Arg, Phe, and Thr of USDDGS were 9 to 45% greater (P &lt; 0.05) than those in BRCBS. The ATTD and the STTD of P in USHPDG and USDDGS were 26 to 42% greater (P &lt; 0.05) compared with BRHPDG and BRCBS. In conclusion, BRHPDG had a greater digestibility of energy and most AA than USHPDG, while the BRCBS evaluated had lower nutritional value than the USDDGS source.

Abstract The objective of this study was to determine the apparent and standardized ileal digestibility (AID and SID) of crude protein (CP) and amino acids (AA) of a corn distillers dried grains with solubles (DDGS) from USA (UDG), a corn bran with solubles from Brazil (CBS) and high protein corn distillers dried grains from USA and Brazil (UHP and BHP), in growing pigs. Fifty crossbred barrows (46.2±5.3kg) were fed a semi-purified N-free diet, used to determine endogenous N losses, or four diets composed of 40% of each ingredient, as the only source of N, substituting for cornstarch in N-free diet. Animals were fed at 2.8 x maintenance (110 kcal of DE per kg of BW0.75) for 9 d and on the 10th d were euthanized for ileal digesta collection. TiO2 was used as an indigestible marker (0.3%) for digestibility calculations. A randomized block design was used, with 10 replicates, using the pig as the experimental unit, and results submitted to orthogonal contrast test. The CBS, UDG, BHP and UHP contained (as-fed basis) 13.9, 25.8, 42.9 and 34.9% CP; 9.0, 6.4, 10.3 and 7.3% EE; 40.8, 40.2, 32.7 and 47.5% NDF; 4.51, 4.53, 5.30 and 4.90 Mcal/kg GE; and 0.40, 0.73, 1.37 and 1.00% Lys, respectively. The AID of CP, Arg, His, Ile, Leu, Lys, Thr and Val; and the SID of His, Leu, Lys, and Val of BHP were 8 to 36% greater (P &lt; 0.05) than those from UHP. The AID of CP, Arg, Ileu, Leu, Phe, Thr, and Trp; and SID of CP, Arg, Phe, and Thr of UDG were 9 to 45% greater (P &lt; 0.05) than those of CBS. In conclusion, BHP had a greater digestibility of most AA than UHP, while the CBS evaluated had lower nutritional value than the UDG source.

Abstract The objective of this study was to determine the effects of an Aspergillus oryzae prebiotic (AOP, Amaferm®) on nutrient digestibility in growing pigs fed high fiber diets. Eighteen growing barrows (initial BW = 50.60 ± 4.90 kg) were surgically equipped with a T-cannula at the distal ileum. Three diets were formulated by including 29.65% corn-distillers dried grains with solubles (DDGS), 36.65% rice bran (RB) or 24.59% wheat middlings (WM) in corn and soybean meal-based diets to meet nutrient requirements for 50 to 75 kg growing pigs. Three additional diets were formulated by supplementing 0.05% AOP at the expense of corn in DDGS (DDGS + AOP), RB (RB + AOP), and wheat middlings (WM + AOP) diets. Pigs were allotted randomly to a triplicated 6 × 2 Youden square design with 6 diets and 2 successive periods. Feces and ileal digesta were collected for 2 d after a 21 d adaptation period, and nutrient content was analyzed to calculate apparent total tract digestibility (ATTD) and apparent ileal digestibility (AID). Standardized ileal digestibility (SID) of amino acids was calculated by correcting AID with basal endogenous amino acid losses determined from the same set of pigs. Supplementation of 0.05% AOP increased (P &lt; 0.05) ATTD of DM, GE, CP, NDF, and ash in DDGS, RB, and WM diets. Diet DE was 35 kcal/kg greater (P &lt; 0.05) in pigs fed AOP supplemented diets compared with those fed diets without AOP. Pigs fed DDGS+AOP diet had greater (P &lt; 0.05) AID of ether extract compared to those fed DDGS diet. However, supplementation of AOP did not (P &gt; 0.05) affect AID of GE, DM, CP, NDF, ash or SID of amino acids. In conclusion, supplementation of AOP in high fiber diets containing DDGS, RB, or WM increased total tract energy value and nutrient digestibility.
