Evaluation of metabolizable energy content of corn distillers dried grain with solubles in adult cockerels with dietary enzyme supplementation

Abstract Characterizing fiber into fermentable and unfermentable fractions may enhance the accuracy of estimating DE and ME energy content in fiber-rich ingredients. Therefore, the objective of this study was to analyze the concentrations of NDF, representing both the fermentable (fNDFom) and unfermentable (uNDFom) portions among sources of corn distillers dried grains with solubles (DDGS), and determine their relative contributions to DE and ME content. The concentrations of DE and ME, as well as apparent total tract digestibility (ATTD) of GE, were measured in a previous experiment. Samples of DDGS (0.5 g) were mixed with fecal inoculum and incubated for 8, 12, and 72 h. The ash corrected NDF (NDFom) content of DDGS residues at each time point was determined. The fNDFom increased with fermentation time of 8 h (21.6%), 12 h (29.0%), and 72 h (68.6%). The ATTD of GE increased as the uNDFom decreased at 8 h (uNDFom8; R2 = 0.83; P < 0.01) and 72 h (uNDFom72; R2 = 0.83; P < 0.01). Likewise, ME content of DDGS increased as uNDFom72 decreased (R2 = 0.59; P < 0.01). The best-fit DE equation was DE (kcal/kg DM) = 2,175 – 3.07 × uNDFom8 (g/kg, DM) – 1.50 × uNDFom72 (g/kg, DM) + 0.55 × GE (kcal/kg DM) (R2 = 0.94, SE = 36.21). The best-fit ME equation was ME (kcal/kg DM) = 1,643 – 2.31 × uNDFom8 (g/kg, DM) – 2.54 × uNDFom72 (g/kg, DM) + 0.65 × GE (kcal/kg DM) – 1.42 × crude protein (g/kg DM) (R2 = 0.94, SE = 39.21). These results indicate that in vitro unfermented fiber is negatively associated with GE and NDF digestibility, and therefore, is a good predictor of DE and ME content in corn-DDGS.

Abstract The objective of this study was to determine the apparent total tract digestibility (ATTD) of DM, GE, EE, NDF, ADF, and CP, the metabolizability of energy, of two high protein (HP) corn distillers dried grain (DDG) and of two corn DDG with solubles (DDGS), from Brazil and USA, and their respective digestible and metabolizable energy content in growing pigs. Fifty crossbred barrows (32.4±6.9kg) were distributed in a randomized block design, with 10 replicates, and received a 96.7 % corn basal diet (BD) or four diets with 40% of each test ingredient: Brazilian HP DDG (BHP); USA HP DDG (UHP); Brazilian DDGS (BDG) and USA DDGS (UDG), substituting for corn. Animals were fed at 2.8 x maintenance (110 kcal of DE per kg of BW0.75) for 7 d adaptation and 4 d of total feces and urine collection. The ATTD of nutrients and energy were calculated by difference and the results were submitted to ANOVA and Tukey’s test (P< 0.05). The BHP and UHP samples contained (as is basis) 92.3 – 89.6% DM, 2.8 – 3.5% ash, 42.9 – 34.9% CP, 10.3 – 7.3% EE, 32.7 – 47.5% NDF, 13.3 – 17.5% ADF, 5.30 – 4.90 Mcal/kg, respectively. The BDG and UDG samples contained (as is basis) 86.1 – 86.1% DM, 4.8 – 4.9% ash, 13.9 – 25.8% CP, 9.0 – 6.4% EE, 40.8 – 40.2% NDF, 13.3 – 14.3% ADF, 4.51 – 4.53 Mcal/kg, respectively. The ATTD of DM and GE and the digestible and metabolizable energy contents of BHP were greater (P< 0.05) than those verified in UHP. The ATTD of DM, GE, NDF, ADF, digestible and metabolizable energy values of BDG were lower (P < 0.05) than those verified in UDG. In conclusion, the BHP presented higher digestible values to almost all parameters evaluated, however, all ingredients presented acceptable digestible contents, indicating they may be used in pigs feeding.

Enzyme Supplementation

The influence of bacterial and fungal enzyme supplements at 0.1 5 and 0.30% of barley based diets on the growth and nutrient utilization of female broiler chickens (Tegel strain) was studied in three experiments. All diets were based on Australian barley cultivars and were fed as mash. Body weight gain was improved by 12 to 25% and food consumption increased by 3 to 21% in supplemented treatments at 4 weeks of age. Diets based on the cultivars Clipper, Ketch and Noyep each grown at Coonalpyn, Port Pirie and Ardrossan in South Australia gave similar growth responses to enzyme supplementation. The metabolizable energy content of the diets was improved by 0.75 MJ kg-1 and 1.53 MJ kg-1 dry matter. An examination of the utilization of dietary nitrogen, soluble sugar, starch, pentosans and soluble �-glucan could not account for the improved metabolizable energy.

Abstract Two experiments were conducted to investigate the effects of a combined α-galactosidase and xylanase preparation on nutrients digestibility and growth performance in broiler chickens. Experiment 1 had 240 broilers allocated to 3 treatments with the dietary supplementation of 0, 300 and 500 g/t of the enzyme combination. Diet and amino acid (AA) digestibility were assessed. Experiment 2 was a 2 × 3 (enzyme × diet) factorial arrangement with 10 replicates of 12 male broilers per replicate. Diets were based on corn-Soybean meal (SBM) diet and had 3 nutritional levels (normal, 2% apparent metabolizable energy (AME) and crude protein (CP) reduction, and 4% AME and CP reduction). Each of these diets was fed with or without enzyme supplementation. Growth performance, chyme viscosity, nutrients digestibility, and endogenous enzymes activity were assessed. In experiment 1, enzyme supplementation improved the digestibility of Ca (P = 0.025) and ileal digestibility of total AA, Pro, Alu, Ile, Lys, His, Thr, Glu, Val, Leu, Tyr and Phe (P < 0.05), and also tended to increase the AME of diets (P < 0.10). In experiment 2, broilers fed the corn-SBM diet with 4% nutrient reduction had better growth performance (P < 0.05), jejunal digesta viscosity at 42 days (P < 0.01), and lower digestibility of gross energy (GE) (P < 0.05) when compared to those fed the normal nutrient diet. Enzyme inclusion increased digestibility of CP (P = 0.044), GE (P = 0.009), raffinose (P < 0.001) and stachyose (P < 0.001), improved average daily gain (P = 0.031), and reduced jejunal digesta viscosity at 42 days (P = 0.011). Besides, similar improvements trend in amylase, trypsin, sucrase, and maltase activity with enzyme inclusion were observed as with energy. These data support that the enzyme supplementation increased nutrients and ileal amino acid digestibility, improved performance and endogenous enzymes activity.
