“…These differences in the nutritional compositions between sieve sizes were similar to results stated by Ileleji et al (2005) and are reflective of nutrient composition depending, at least to some extent, on the particle size distribution (Liu, 2008). In fact, Wu and Stringfellow (1982;1986) found that chemical constituents varied according to particle size, and this could be exploited to fractionate DDGS. Additionally, we note that there are no fixed zones where protein and carbohydrates resided separately.…”

Cereal Chem. 86(4):410-420With the U.S. fuel ethanol industry projected to grow during the next several years, supplies of distillers dried grains with solubles (DDGS) are anticipated to continue to grow as well. DDGS is used primarily as livestock feed. Much of the DDGS must be shipped, often over large distances, outside the Corn Belt (which is where most of the corn-based ethanol plants are currently located). Stickiness and caking among particles is a common issue for DDGS, and it often leads to flowability problems. To address this, the objective of this study was to understand the cross-sectional and surface natures of DDGS particles from five ethanol plants, and how they interact with DDGS properties. This study examined the distribution patterns of chemical components within cross-sections, within section edges (i.e., surface layers), and on surfaces using standard staining techniques; chemical composition was determined using standard protocols; and physical and flowability properties were also determined.Crude protein in the samples was 28.33-30.65% db, crude fat was 9.40-10.98% db, and neutral detergent fiber (NDF) was 31.84-39.90% db. Moisture contents were 4.61-8.08% db, and geometric mean diameters were 0.37-0.52 mm. Cross-sectional staining showed protein levels of 19.57-40.39%, and carbohydrate levels of 22.17-43.06%, depending on the particle size examined and the production plant from which the DDGS was sampled. Staining of DDGS particles indicated a higher amount of surface layer protein compared with carbohydrate thickness in DDGS particles that had a lower flow function index (which indicated potential flow issues). Additionally, surface fat staining suggested that higher surface fat also occurred in samples with worse flow problems. This study represents another step toward understanding why DDGS particles stick together during storage and transport, and will hopefully help to improve DDGS material handling strategies.

“…Result from the present study suggests that DDGS can be utilized in milkfish diets by as much as 450 g/kg inclusion by replacing soybean meal without affecting growth performance parameters. The same positive effect of DDGS on growth performance has been reported in other fish species such as rainbow trout (Cheng & Hardy, ; Cheng et al., ; Øverland, Krogdahl, Shurson, Skrede, & Denstadli, ), channel catfish (Li et al., ; Tidwell, Webster, Yancey, & D'Abramo, ; Zhou, Zhang, Davis, & Lim, ) and tilapia (Wu, ). The positive effects of DDGS on fish growth can be attributed to the residual yeast present in DDGS (Øverland et al., ).…”

“…Various studies have been conducted on the use of DDGS in fish diets, such as in rainbow trout Oncorhynchus mykiss (Cheng & Hardy, ,b; Cheng, Hardy, & Blair, ; Stone, Hardy, Barrows, & Cheng, ), catfish Ictalurus punctatus (Li & Robinson, ; Li, Robinson, Oberle, & Lucas, ), tilapia Oreochromis sp. (Tidwell, Coyle, VanArnum, Weibel, & Harkins, ; Wu, ) and sunshine bass Morone chrysops × Morone saxatilis (Thompson et al., ). Such studies reported that up to 40% of DDGS in fish diets did not negatively affect fish performance and feed efficiency.…”

A 90-day feeding trial was conducted on milkfish, Chanos chanos with an initial mean body weight of 3.07 ± 0.17 g (mean ± standard error of mean). Six treatment diets were formulated to contain 0 g/kg (Diet 1), 150 g/kg (Diet 2), 25 g/ kg (Diet 3), 300 g/kg (Diet 4), 350 g/kg (Diet 5) and 450 g/kg (Diet 6) distiller's dried grain with soluble (DDGS). All the dietary treatments were isonitrogenous (350 g/kg crude protein) and isolipidic (6% crude lipid). Result of the feeding trial indicated that growth rates, feed intake and feed efficiency were not significantly (p > .05) affected by inclusion levels of DDGS by up to 450 g/kg in the feed.Proximate body composition (crude protein, crude lipid, ash, fibre) in fish fed the dietary treatments were not significantly (p > .05) affected as well. The DDGS when used as a milkfish ingredient has a protein digestibility of 910 g/kg, fat disgetsibility of 850 g/kg, carbohydrate digestibility of 750 g/kg and a dry matter digestibility of 520 g/kg Results from the intestinal morphology displayed no apparent pathological changes in the digestive tract of fish fed all dietary treatments. These results indicate that DDGS can be efficiently utilized by milkfish by up to 450 g/kg without negatively affecting performance parameters and intestinal morphology.

“…When dried, the distillers grains contain mostly proteins and fiber, whereas the condensed distillers solubles contain mostly residual sugars (Wu, 1994) and oil. During drying, the condensed distillers solubles are added back to the wet distillers grains; the amount added as well as the drying conditions contribute to the differences in the composition and nutritional value of corn distillers dried grains with solubles.…”

Contribution of exogenous dietary carbohydrases to the metabolizable energy value of corn distillers grains for broiler chickens

et al. 2010

The objectives of this study were to determine the ileal digestible energy (IDE), ME, and ME(n) contents of corn distillers grains (CDG) for broiler chickens and to quantify these energy utilization responses to carbohydrase supplementation by the regression method. The CDG sample used in the current experiment contained (by analysis) 936 g/kg of DM, 4,894 kcal/kg of gross energy, 315.1 g/kg of CP, 94.6 g/kg of crude fat, 94.8 g/kg of crude fiber, 495.6 g/kg of neutral detergent fiber, 179.1 g/kg of acid detergent fiber, 0.19 g/kg of Ca, and 4.8 g/kg of P. The studies were conducted at 2 locations (Purdue or Louisiana State University) and CDG were incorporated into a practical corn-soybean meal diet at 3 levels (0, 300, or 600 g/kg) without or with added carbohydrase in a 2 x 3 x 2 factorial arrangement. The carbohydrase premix was added to supply 2,000 U of xylanase + 1,800 U of amylase/kg of feed. The diets were fed to 288 broiler chickens from d 15 to 22 posthatch with 6 birds per cage and 8 replicate cages per diet in a randomized complete block design at each of 2 locations. The broiler chicks were fed a standard broiler starter diet from d 1 to 15 posthatch. The IDE of diets decreased both linearly (P < 0.01) and quadratically (P < 0.05) as CDG increased from 0 to 600 g/kg regardless of carbohydrase supplementation. There was a linear (P < 0.01) decrease in ME of diet from 3,239 to 2,510 kcal/kg as CDG increased from 0 to 600 g/kg in the diets without added carbohydrase, whereas for birds fed the carbohydrase-supplemented diets, there were both linear (P < 0.01) and quadratic (P < 0.01) decreases from 3,398 to 2,613 kcal/kg as CDG increased from 0 to 600 g/kg. Dietary ME(n) linearly decreased (P < 0.01) regardless of carbohydrase supplementation as CDG increased from 0 to 600 g/kg. Supplementation with carbohydrase improved (P < 0.01) IDE, ME, and ME(n). Regressions of CDG-associated IDE, ME, or ME(n) intake in kilocalories against kilograms of CDG intake without added carbohydrase generated the following: IDE = 44 + 2,340X, r(2) = 0.953; ME = 10 + 2,315X, r(2) = 0.993; and ME(n) = 10 + 2,132X, r(2) = 0.991. Corresponding regressions when carbohydrase was added were as follows: IDE = -17 + 2,622X, r(2) = 0.985; ME = -25 + 2,448X, r(2) = 0.979; and ME(n) = -22 + 2,264X, r(2) = 0.978. These data indicate that the respective IDE, ME, and ME(n) values (kcal/kg of DM) of the CDG sample evaluated were 2,340, 2,315, and 2,132 when carbohydrase was not added and 2,622, 2,448, and 2,264 when carbohydrase was added. Comparison using ANOVA procedures indicated that the slope when carbohydrase was added was greater (P < 0.05) than when carbohydrase was not added. This response implies that carbohydrase supplementation improved (P < 0.05) the IDE, ME, and ME(n) of CDG in practical corn-soybean meal-based diets used in this current study by 12, 5.7, and 6.2%, respectively.
