“…A previous study reported low AID values for indispensable AA (52.0% to 87.0%) in soft winter wheat (Haydon and Hobbs, 1991), and the result for the low AA digestibility may be caused by the high albumin, globulin, and gliadin protein, which contain low contents of AA and decrease AA digestibility (Shewry and Halford, 2002;Liu, 2011b). In the present study, Lys and Thr were the least digestible indispensable AA, which was in agreement with previous studies for Lys (Pedersen et al, 2007;Hennig et al, 2008) and Thr (Widyaratne and Zijlstra, 2008). The reason for the low SID of Lys is because the main portion of Lys is in the aleurone fraction of wheat which is known for its low digestibility (Green et al, 1987).…”

This study was conducted to determine the DE, ME, and apparent (AID) and standardized ileal digestibility (SID) of AA in different wheat cultivars fed to growing pigs. In Exp. 1, twelve crossbred growing barrows were allotted to a replicated 6 × 6 Latin square design to determine the DE and ME contents of 12 different wheat cultivars. In Exp. 2, twelve growing barrows with a simple T-cannula were used to determine the AID and SID of AA in 10 different wheat cultivars. Pigs were randomly allotted to a replicated 6 × 6 Latin square design and fed one nitrogen-free diet and 10 different cultivars of wheat diets. Among different wheat cultivars, the concentrations of GE, CP, NDF, ADF, and starch ranged from 4,385 to 4,458 kcal/kg, 12.95% to 18.14%, 9.16% to 13.89%, 1.93% to 2.92% and 60.81% to 70.77%, respectively (DM basis). There were significant differences (P < 0.05) in the DE, ME values, and the ATTD of GE in 12 different cultivars of wheat in Exp. 1. The DE and ME contents and the ATTD of GE ranged (P < 0.05) from 3,922 to 4,067 kcal/kg DM, 3,759 to 3,941 kcal/kg DM and 88.14% to 90.31%, respectively. The best prediction equations of DE and ME for different cultivars of wheat cultivars were DE = −2,738 -(40.8 × % ADF) + (1.7 × GE) -(51.5 × % Xylans) -(95.7 × % Ash) + (22.3 × % EE), R 2 = 0.98, and ME = −2,990 + (1.7 × GE) -(50.2 × % Xylans) -( 87.6 × % Ash), R 2 = 0.88, respectively. There were also differences (P < 0.05) in the AID and SID of CP and indispensable AA, expect for His, in 10 wheat cultivars in Exp. 2. The AID and SID of CP, Lys, and Met ranged (P < 0.05) from 82.02% to 89.46%, 74.13% to 84.73%, 87.35% to 92.49% and 87.56% to 94.04%, 80.56% to 89.89%, 89.56% to 94.45%, respectively. In conclusion, the chemical composition, energy contents, and most AA digestibility in different cultivars of wheat varied widely.

“…Furthermore, it has been reported that direct method did not underestimate the AID of AA in wheat compared with difference Table 7. Differences between measured and predicted values for apparent ileal digestibility (AID, %) of crude protein and amino acids in mixed diets and regression methods (Hennig et al, 2008), which supports the use of wheat as sole source of nitrogen to determine AID of AA. The wheat-CM-MBM and wheat-MBM-DDGS diets contained same levels of wheat and MBM to elucidate whether there was different effect between CM and DDGS on additivity of AID of CP and AA determined with the same marker.…”

The aim of this study was to investigate the additivity of apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in mixed diets containing wheat, canola meal (CM), meat and bone meal (MBM), and sorghum distillers' dried grains with solubles (DDGS) fed to pigs with chromic oxide (Cr2O3) and titanium dioxide (TiO2) as digestibility index markers. Four diets were prepared to contain wheat, CM, MBM, or DDGS as a sole source of nitrogen; three mixed diets were prepared to contain wheat, CM, and MBM; wheat, MBM, and DDGS; or wheat, CM, MBM, and DDGS; also, a nitrogen-free diet was prepared to estimate the basal ileal endogenous losses (BEL) of CP and AA. Both Cr2O3 and TiO2 were incorporated at 5 g/kg into each diet. Sixteen barrows (initial body weight = 34.7 ± 0.6 kg) surgically fitted with T-cannulas at the distal ileum were allotted to a duplicate 8 × 4 Youden square design with eight experimental diets and four periods. During each 7-d period, the ileal digesta was collected for 2 d after a 5-d adaptation, and the AID and SID of CP and AA were determined using Cr2O3 or TiO2 as marker. There was no interaction between diet and marker type for both AID and SID of CP and AA. Similar BEL, AID, and SID of CP and AA were determined by Cr2O3 and TiO2. In the wheat-CM-MBM diet, the measured AID of CP and most AA determined with Cr2O3 or TiO2 were not different from the predicted values, which was determined based on the measured AID values in wheat, CM, and MBM. In the wheat-MBM-DDGS diet, the measured and predicted AID of CP and seven indispensable AA differed (P < 0.05) using Cr2O3 as marker, and the measured and predicted AID of CP and four indispensable AA differed (P < 0.05) using TiO2 as marker. The measured AID of CP and most indispensable AA were greater (P < 0.05) than predicted AID regardless of marker type for the wheat-CM-MBM-DDGS diet. The measured SID of CP and indispensable AA were consistent with the predicted values, except Lys in the wheat-CM-MBM diet using either marker and His in the wheat-MBM-DDGS diet with Cr2O3 as marker. In conclusion, more accurate prediction of ileal digestibility of CP and AA was achieved using SID rather than AID in mixed diets containing wheat, CM, MBM, and DDGS. The determination of endogenous loss, AID, and SID of CP and AA were not affected by marker type in this study. In addition, the additivity of AID and SID of CP and most indispensable AA in mixed diets was not affected by marker type.

“…In wheat, lowest SID values are generally observed for lysine (Pedersen et al, 2007;Hennig et al, 2008), but also for threonine (Widyaratne and Zijlstra, 2007b). The low SID of lysine has been attributed to its relatively low content compared to the other AA in wheat (Fan et al, 1993).…”
