This book was released on 2017 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four dual-flow continuous fermenters were used in a Latin square design to determine the apparent ruminal digestibility and ruminal characteristics of diets containing dried distillers grains plus solubles (DDGS) at various levels of fat content. Fermenters were randomly assigned to one of the following treatments: 1) 40% DDGS containing 4.82% fat content (40 LOW); 2) 40% DDGS plus corn oil to obtain 7.5% fat (40 MED); 3) 40% DDGS plus corn oil to obtain 10.5% fat (40 HIGH); or 4) 70% DDGS plus corn oil to obtain 7.5% fat (70 MED). Rumen fluid was collected at the beginning of each period from two ruminally cannulated Angus cows previously adapted to the 40LOW treatment. Each period consisted of 10 days with a seven day adaptation period followed by three days of sample collection. Calories per gram of diet increased as percent fat increased and calories per gram was greater at the 70% inclusion of DDGS compared to 40% inclusion of DDGS at all levels of fat content. However, level of fat in the diet did not influence (P ≥ 0.35) apparent ruminal digestibility of DM, NDF, ADF, CP or total calories. Similarly, inclusion rate of DDGS had no influence (P ≥ 0.35) on nutrient digestibility. Ammonia concentrations were greatest (P = 0.0002) for 70 MED compared to the other treatments. However, treatment had no impact (P ≥ 0.16) on volatile fatty acid production with the exception of propionate which increased (P =0.05) as the level of DDGS increased from 40 to 70% inclusion rate. This data would suggest that level of fat content of DDGS has no negative influence on apparent ruminal digestibility and select ruminal characteristics. From an economic perspective, higher fat DDGS should have a higher price differential, but lower fat DDGS can still be an effective protein and energy substitute.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three trials were conducted using dried distiller's grains with solubles (DDGS) to evaluate effects on feedlot performance, carcass characteristics, ruminal fermentation, and diet digestibility in cattle fed steam-flaked corn-based diets. In trial 1, crossbred yearling heifers were used in a finishing trial to evaluate interactions between corn-DDGS feeding levels and roughage source (alfalfa hay vs corn silage) in terms of impact on feedlot performance and carcass characteristics. Experimental diets were based on steam-flaked corn and contained 0% DDGS with 6% alfalfa hay (AH), 0% DDGS with 10% corn silage (CS), 25% DDGS with 6% AH, or 25% DDGS with 10% CS (DM basis). Results indicated no interaction between levels of DDGS and roughage source. Heifers fed DDGS as a partial replacement for steam-flaked corn had similar growth performance and carcass merit compared to heifers fed diets without DDGS. Corn silage and alfalfa hay were comparable roughages when a portion of steam-flaked corn was replaced with DDGS. The second trial was a companion metabolism study in which ruminal fermentation characteristics and diet digestibility were examined in 12 cannulated Holstein steers fed steam-flaked corn finishing diets with or without DDGS, using alfalfa hay or corn silage as roughage sources. Diets were similar to those fed in the performance study and consisted of steam-flaked corn with 0 or 25% DDGS (DM basis) and 6% AH or 10% CS (DM basis). Feeding DDGS decreased ruminal pH and ruminal ammonia concentrations, and digestion of DM and OM were less compared to diets without DDGS. The decrease in digestibility was largely attributable to poorer digestion of CP and, to a lesser extent, a reduction in starch digestion. The third study was designed to investigate effects of pH (5.0, 5.5, and 6.0) on in vitro fermentative activity by ruminal microorganisms from cattle adapted to a finishing diet containing 25% DDGS (DM basis). Higher pH led to greater dry matter disappearance in vitro (P

This book was released on 2005 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to evaluate corn distiller's solubles (CDS), a co-product from dry grind ethanol plants, in beef steers fed corn-based diets. In Exp. I, four pens of steers were fed for 109 d diets containing 0, 4, 8 or 12% CDS. Daily feed, gain and gain/feed were 9.4, 10.1, 10.0, and 10.1 (kg/d); 1.75, 1.78, 1.76, and 1.79 (kg/d); 0.185, 0.177, 0.176, and 0.179; for the four respective diets. Feed intake increased when CDS was fed (P = 0.012). Gain, gain/feed, and carcass traits were not statistically different (P> 0.1). In Exp. II, ten steers were used in a digestion study to evaluate diets containing 4 and 8% CDS, or 10 and 20% wet corn distillers grain with solubles (WDGS). The steers were placed in digestion crates for total collection of feces and urine. Intake (kg/d) of DM, starch, NDF, ADF, CP, and fat were: 7.99, 8.71, 8.62 & 8.41, 7.83; 4.92, 4.87, 4.93, & 4.81, 3.95; 1.19, 1.25, 1.19, & 1.42, 1.42; 0.43, 0.48, 0.45, & 0.56, 0.55; 0.96, 1.08, 1.03, & 1.03, 1.03; 0.27, 0.35, 0.43, & 0.43, 0.50; for 0, 4 or 8% CDS and 10 or 20% WDGS. Respective apparent digestibility of DM, starch, NDF, ADF, CP, and fat were 79, 78, 76 & 77, 76; 97, 94, 95, & 95, 94; 53, 52, 46 & 52, 56; 41, 45, 37, & 48, 50; 72, 72, 70, & 69, 69; 63, 66, 65, & 68, 75. Feeding distillers co-products did not affect DM intake or digestibility of NDF, ADF, or CP (P> 0.05), but did increase fat intake (P

Available in PDF, EPUB and Kindle. Book excerpt: Four studies evaluated effects of dry distillers grains with solubles (DDGS) containing high S concentrations on feedlot performance, ruminal fermentation, and diet digestibility by finishing cattle. Trial 1 used finishing steers fed diets based on steam-flaked corn (SFC) or dry-rolled corn (DRC), and containing 30% DDGS (DM) with 0.42% S (0.42S) or 0.65% S (0.65S). No interaction (P [equal to or greater than] 0.15) between dietary S and grain processing occurred, but feeding 0.65S decreased DMI (P 0.001) and ADG (P = 0.006) by 8.9% and 12.9%, respectively, whereas G:F was unaffected by S concentration (P = 0.25). Steers fed 0.65S had 4.3% lighter HCW (P = 0.006), lower KPH (P = 0.009), and lower yield grades (P = 0.04) than steers fed 0.42S. Concentration of H2S was inversely related (P [equal to or less than] 0.01) to ADG (r = -0.58) and DMI (r = -0.67) in cattle fed SFC, and DMI (r = -0.40) in cattle fed DRC. Trial 2 used the same treatments as in the first stud, and investigated ruminal fermentation characteristics and diet digestibility by feedlot cattle. Feeding 0.65S increased ruminal pH (P 0.05), but decreased total VFA concentrations (P = 0.05). Steers fed 0.65S had greater ruminal NH3 concentrations (P 0.01) than steers fed 0.42S. The magnitudes of these effects were greater in steers fed DRC than in steers fed SFC (interaction, P

Download or read book Impact of Ethanol Process Changes on Distillers Grains for Beef Cattle written by Shelby A. Garland and published by . This book was released on 2018 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distillers grains plus solubles (DGS) have been widely utilized in beef cattle diets. Fractionation of the corn kernel pre- and post-fermentation has changed the composition of DGS and allowed for the production of other feed byproducts over time. The use of fractionated DGS and other feed byproducts from the ethanol industry has not been heavily researched in beef cattle diets. Three experiments were conducted to evaluate the effect of feeding high protein distillers grains (HiPro DDG) and corn bran plus solubles (Bran + Solubles) in beef cattle diets. Experiment 1 evaluated the effect of byproduct type on finishing performance and carcass characteristics. Experiment 2 evaluated the effect of byproduct type on nutrient digestibility, ruminal pH, ruminal VFA production, and in vitro gas production. Byproducts replaced corn at 40% of diet DM in Exp. 1. Experiment 3 compared feeding Bran + Solubles to wet DGS at 20 and 40% of diet DM compared to a corn control. In Exp. 2, Feeding HiPro DDG or Bran + Solubles resulted in decreased digestibility compared to corn or traditional wet and dry DGS, but increased energy intake. Traditional wet and dry DGS also resulted in decreased digestibility while energy intake was increased. Volatile fatty acid profiles and pH parameters were not different across treatments. Feeding HiPro DDG and Bran + Solubles improved gains and feed efficiency compared to traditional dry or wet DGS and corn. Compared to wet DGS, Bran + Solubles resulted in similar performance and carcass characteristics. Increased inclusion of both byproducts resulted in a linear increase in carcass weight. Overall, nutrient digestibility for HiPro DDG or Bran + Solubles is similar to traditional wet or dry DGS while performance was increased.

Ahern and published by . This book was released on 2014 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four growing experiments were conducted to evaluate the use of dry rolled corn (DRC) and either dry (DDGS) or wet distillers grains plus solubles (WDGS) as energy sources in high forage diets. In Exp. 1, steers were fed a blend of sorghum silage and alfalfa hay and supplemented 1 of 4 inclusions of WDGS, DDGS or a MIX (67% WDGS: 33% Straw). In Exp. 2, Exp. 3 and Exp. 4, steers were fed diets including WDGS, DDGS or DRC at different inclusions, replacing sorghum silage and grass hay. In Exp. 1, WDGS, DDGS and MIX produced greater ending BW, ADG and G:F compared to the basal diet. Increasing distillers grains improved ADG and G:F in forage based diets. Data from Exp. 2 - 4 were pooled and ADG was regressed against inclusion thereby allowing the energy value of WDGS to be calculated relative to that of DRC. The energy value of WDGS was 137% and 136% of DRC when fed at 15 and 30% of the diet DM, respectively. In vitro digestibility and in vivo digestibility estimates are highly correlated but absolute values differ. Therefore, our objective was to determine in vivo digestibilities of 5 forages and use these forages as standards for in vitro digestibility procedures when in vivo estimates are needed for unknown forage samples. Eight in vitro runs were conducted using 5 hay standards and 6 forage samples with unknown in vivodigestibilities in order to predict actual in vivo values from in vitro estimates. Runs were evaluated using either regression equations or standard mean adjustment. Using regression equations increase forage*run variation. Forage*run variation decreased using the standard mean adjustment. Standard mean adjustment appears to be a valid method to adjust IVOMD values and estimate in vivo digestibility.

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: All dry milling ethanol plants produce wet distillers grains (WDG) and distillers solubles (DS). Depending on the plant, WDG and DS will be combined to produce wet distillers grains plus solubles (WDGS). Some plants will partially dry WDGS and market modified distillers grains plus solubles (MDGS), or other plants will completely dry WDGS to produce dried distillers grains plus solubles (DDGS). These products have been shown to contain greater feeding values than the corn it replaces in finishing diets. However, as drying intensity of distillers grains plus solubles (DGS) increases, the feeding value relative to corn decreases. Three finishing experiments and two metabolism experiments were conducted to evaluate the effect drying WDGS has on finishing cattle performance and carcass characteristics and the effects on nutrient digestibility. Diets containing DGS had greater ADG and were more efficient than the corn-based control. As a result, cattle fed DGS had heavier HCW and greater 12th rib fat thickness at harvest. Using the G:F values, all types of DGS regardless of moisture content had greater feeding values than the corn it replaced. Additionally, WDGS had greater feeding values than MDGS and DDGS, and MDGS had a greater feeding value than DDGS. Although not significant, diets containing WDGS had numerically greater NDF digestibility than diets containing DDGS. Organic matter digestibility was improved for WDGS compared to DDGS. Completely and partially drying WDGS reduces the feeding value in finishing diets and reduces OM digestibility.
