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

Boyd and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three feedlot experiments evaluated the effects of added urea to finishing diets containing less than 20% WDGS. In Exp.1, a significant interaction was observed for G:F between urea concentration and distillers concentration in the diet. Feeding urea in diets with 10% WDGS had no significant impact on animal G:F. Urea included in diets with 15% WDGS had a quadratic impact on G:F with urea included at 0.5% of diet DM having the greatest performance. When adding urea to diets containing 20% WDGS, a quadratic impact on G:F was observed where urea included at 0.5% of diet DM reduced G:F. In Exp. 2 there were no interactions between urea concentration and WDGS concentration. Increasing concentration of WDGS in the diet improved G:F by 4.7%. The addition of urea to the diet had minimal impact on performance although cubic effects of urea inclusion were observed suggesting variation in the data. For Exp. 3 no difference was observed, for either urea concentration or WDGS concentration in the diet, however, DMI was reduced when urea was included in the diet at 1.2%.Two experiments evaluated the effects of the addition of yeast extracted solubes (EXP) and yeast to finishing diets on performance, carcass characteristics, and nutrient metabolism. In Exp. 1, feeding increased EXP in the diet resulted in quadratic effects on performance with what appears as a linear decrease up to 15% EXP is included followed by a dramatic increase at 20% inclusion. Feeding similar concentrations of EXP when compared to conventional condensed distillers solubles (CONV) reduced animal performance. However, when yeast (YST) was added back to the EXP, performance is similar to CONV. Adding YST alone does not improve performance over the corn control. All concentrations of EXP and CONV performed worse than the corn control. In Exp. 2 no effects on measured nutrient digestibility were observed. However, DM intake and excretion were affected with tendencies for OM, NDF, ADF, and starch intakes to be affected. Digestible energy intake in Mcal/kg and TDN were affected by diet and appeared to follow similar patterns as the performance trial perhaps explaining the observed performance response.

Download or read book Evaluation of Corn Condensed Distillers Solubles in Beef Cattle Diets and Grazing Double cropped Forages Following Corn Harvest written by Benjamin H. Hansen and published by . This book was released on 2017 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn condensed distillers solubles (CDS) is a protein and energy dense by-product from dry-milled production of ethanol. Recent oil extraction has posed modifications to the nutrient profile of CDS, suggesting that de-oiled CDS needs to be re-evaluated in beef cattle diets. Three experiments were conducted to evaluate the effects of CDS in high-concentrate diets, forage-based diets, as well as evaluate the effects of CDS on diet digestibility and rumen fermentation parameters in forage-based diets. Feeding CDS in high-concentrate diets up to 20% of the diet DM or in combination with wet distillers grains plus solubles (WDGS) improved performance and resulted in greater energy value compared to corn. Feeding values of 20% CDS or the combination of 16% CDS and 20% WDGS were 147 and 129% compared to corn, respectively. Feeding CDS in forage-based diets up to 40% of the diet DM diminished performance and resulted in a lesser energy value compared to corn. Linear decreases were observed in total tract digestibility of NDF and the acetate to propionate ratio in rumen fluid. Double-cropped forages following corn harvest offer livestock producers an opportunity to extend their grazing season on high quality forage in the fall. Additionally, crop producers may benefit from the implementation of grazing animals due to added soil nutrients and removal of residue. Therefore, an experiment was conducted to evaluate the effects of double-cropped oats following corn silage (CS) or high-moisture corn (HMC) on calf gains, forage production, and subsequent cash crop yields. Oats seeded after CS produced more forage biomass than oats seeded after HMC. Both treatments produced high quality oats (22% CP, 39% NDF, and 24% ADF averaged across treatments). Calf gains were greater grazing oats following CS compared to HMC at 1.10 and 0.84 kg / d, respectively. Across 1-yr of data, subsequent cash crop yields were not different for HMC and soybeans with increased CS yields in both covered/grazed and non-covered/non-grazed treatments compared to the covered/non-grazed treatment..

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.

This book was released on 2016 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its entirety this dissertation intended to address the impact of feeding several forms of de-oiled corn distillers grains plus solubles and the effect of supplementing OmniGen-AF as a potential antioxidant source for extending beef shelf life. In study one we learned that despite the de-oiling process, greater inclusion levels (65%, DM basis) of de-oiled wet distillers grains plus solubles (WDGS) causes an increase in polyunsaturated fatty acids (PUFA) similar to the levels obtained with full-fat WDGS. Lower inclusion levels (35 and 50%, DM basis) of de-oiled WDGS have intermediate PUFA content in comparison to 65% de-oiled WDGS, full-fat WDGS and a corn control diet (P 0.01). In study two cattle finished with 50% de-oiled dry distillers grain plus solubles (DDGS) also resulted in an increased PUFA content in muscle in relation to a corn control group (P

Available in PDF, EPUB and Kindle. Book excerpt: With the large expansion of the ethanol industry in previous years, there has been an increase in supply of distillers grains plus solubles (DGS) for the feedlot industry. Distiller's grains are a common byproduct used in feedlot diets for added protein or energy. Recently, ethanol companies have been using different extraction techniques to remove various parts of the DGS to sell separately, such as corn oil and fiber. Previous research trials have tried to determine the contribution of individual nutrients in distillers grains that improve performance in order to predict the impact of removing certain components. In previous studies, fiber has shown the greatest contribution; however, no sole nutrient has been identified that contributes to providing equal performance to distillers grains. Therefore, a study was conducted to determine the value of the fiber in modified distillers grains plus solubles for finishing cattle performance. In that study, the conclusion was made that the isolated fiber component does not give equal performance to feeding MDGS due to a reduction in G:F and feeding value if only the fiber components replaced corn, which means the energy in MDGS is provided by other components to make it better than corn. Some producers are concerned that feeding de-oiled DGS will have a negative impact on finishing cattle performance. Currently, some feedlots have been adding corn oil back to diets to ensure they are getting the best performance possible. Although corn oil has been added to diets in the past and experiments have been done to evaluate de-oiled versus normal DGS, there has never been a study that evaluated the removal of corn oil from distillers grains compared to adding corn oil back to de-oiled distillers grains. Therefore, two finishing studies were completed to determine the effects of the removal of corn oil from modified distillers grains plus solubles and replacement with supplemental corn oil on finishing cattle performance and total tract digestibility. When corn oil was added back to MDGS, there was a negative impact on digestibility of OM and NDF as well as lower DE (Mcal/kg) compared with de-oiled MDGS or full fat MDGS. When 2% corn oil was added back to de-oiled MDGS, there was a 4.9% improvement in F:G compared to de-oiled MDGS. There was a numerical improvement in F:G by 3.7% for MDGS + Oil compared to FF MDGS.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wet distiller's grains with solubles are the most common feedstuff generated by the ethanol industry, and this feedstuff has been utilized by the feedlot industry. Exploration of the effect of dietary distiller's inclusion on the form and quantity of protein or nitrogen (N) has received little attention. Assessment of degradable N needs in diets containing wet distiller's grains with solubles (WDGS) is needed to aid the cattle feeding industry in managing feed costs and potential environmental issues. In Exp. 1, 525 yearling steers (initial weight = 373 ±13 kg) received treatments in a 2 x 3 1 factorial. Factors included corn WDGS (15 or 30 percent of DM) and non-protein N (NPN; 0, 1.5, or 3.0 percent of DM) from urea. The control diet without corn WDGS contained 3.0 percent NPN (1.06 percent urea) and cottonseed meal. Overall gain efficiency among steers fed 15 percent corn WDGS was greatest for 1.5 percent NPN and least for 0 percent NPN (P = 0.07, quadratic), whereas gain efficiency decreased linearly (P 0.09) as NPN increased in the 30 percent WDGS. Dressing percent was greater (P 0.01) for the control diet than for 15 percent or 30 percent WDGS. In Exp. 2, 296 steer calves (initial BW = 344 ±12 kg) were adapted to a common finishing diet, blocked by BW, and assigned to treatments. Experimental diets included a control diet without WDGS (contained 3 percent NPN from urea, and cottonseed meal) and 15 percent WDGS with either 1.50, 2.25, or 3.00 percent NPN (0.52, 0.78, and 1.04 percent urea, respectively, on a DM basis). Overall gain efficiency on either a live or adjusted basis was not different among treatments (P 0.15). Dietary NPN concentration did not influence growth performance (P 0.21). Results suggest that optimum performance for cattle fed 15 percent WDGS occurred when the diet contained between 1.5 percent and 2.25 percent NPN. However, removing all supplemental NPN was necessary to support optimum performance in diets containing 30 percent WCDG.

This book was released on 2010 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to examine the effects of 70% (DM) inclusion of dried distillers' grain with solubles (DDGS) on performance and meat quality. Ninety-six Angus steers (276 kg ± 7.5 kg initial BW) were used in an completely randomized design with incomplete replication. Steers were stratified by BW to pens and pens were randomly assigned to one of 6 treatments: 1) 80% corn; 5% soybean meal; 15% corn silage, fed as a negative control (CON ); 2) 40% DDGS: 45% corn: 15% corn silage, fed as a positive control ( PCON ); 3) steers received PCON (0-84d) then switched to a diet of 70% DDGS: 15% corn: 15% corn silage until finished (40/70 ); 4) steers started on 70% DDGS: 15% corn: 15% corn silage (0-84d) then switched to PCON until finished ( 70/40 ); 5) CON + soybean meal, isonitrogenous to PCON ( N40 ); 6) CON + corn oil, isocaloric to PCON ( E40 ). Steers were fed respective treatments until 80% of them reached low choice or higher by visual appraisal, providing their genetics allowed (168 and 213 days) The data of this study suggests that it is possible to feed 70% DDGS in feedlot rations with little to no adverse effects on growth performance or meat quality.

Available in PDF, EPUB and Kindle. Book excerpt: Cattle feeders are considering alternative feedstuffs to replace expensive corn grain and decrease rations costs. Feeding corn silage allows cattle feeders to take advantage of the entire corn plant at a time of maximum quality and tonnage as well as secure substantial quantities of roughage and grain inventory. Distiller's grains have proven to be economical and are now a commonplace ingredient in feedlot finishing diets. Experiments were conducted to determine the effects of feeding increased concentrations of corn silage in replacement of corn grain in finishing diets containing distillers grains. Feedlot gains and gain:feed ratios were reduced as corn silage increased in the diet. Total tract dry matter digestibility of diets containing 45% corn silage was decreased compared to diets containing 15% corn silage. Although total tract neutral detergent fiber (NDF) concentration was not different across corn silage inclusions, in-situ NDF disappearance of corn bran was greater for diets with increased corn silage inclusion. Whole corn plants were sampled and analyzed for two consecutive years for determination of the effects on whole corn plant yield and quality measurements due to hybrid season length, planting density, and whole plant harvest timing. As whole plants were harvested later in the season, yield increased with minimal changes in whole plant quality measures. The economic factors involved in pricing corn silage were assessed, and different economic scenarios were developed for feeding corn silage in finishing diets containing distillers grains. Feeding increased concentrations of corn silage in finishing diets containing distillers grains was determined economical when corn grain price was above $163.38 per metric tonne. As well, as corn grain price and the inclusion of corn silage in the diet increased, reducing corn silage shrink and harvesting corn silage at higher DM contents became more economically beneficial. These data demonstrate that corn silage can economically replace corn grain in finishing diets containing distillers grains.

This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four experiments were conducted to determine the impact of dried distillers' grains with solubles (DDGS) on greenhouse gas (GHG) emissions from beef cattle. The first compared in vitro methane (CH4) production from corn DDGS (CDDGS, ~30% crude protein [CP]) and wheat DDGS (WDDGS, ~40% CP dry matter [DM]). Wheat DDGS or CDDGS replaced barley silage at 20, 40, 60, 80 and 100% DM. Methane (mg CH4/g DM) was lower for CDDGS than WDDGS at up to 80% DM. In a second experiment, heifers fed a growing (high silage) diet showed a reduction in CH4 (g CH4/kg DM intake [DMI]) when 35% barley grain and 5% canola meal DM were replaced with CDDGS (10.0% fat DM). Inclusion of 40% WDDGS (4.1% fat DM) had no effect on enteric CH4 emissions. In contrast, feeding 40% DM WDDGS with added corn oil (9.5% fat DM) reduced CH4 to the same extent as CDDGS. In a third experiment, replacing 40% DM barley grain with CDDGS (9.7% fat DM) in a finishing (high grain) diet reduced CH4 (g/kg DMI). Whereas feeding 40% DM WDDGS along with corn oil (9.9% fat DM) resulted in similar CH4 losses as CDDGS. Results from both in vitro and in vivo experiments indicate that the higher fat content of CDDGS vs. WDDGS was responsible for CH4 reductions. The benefit of replacing 40% DM barley grain with CDDGS or WDDGS on GHG emissions from beef production was further evaluated using life cycle assessment. Replacing barley grain with CDDGS or WDDGS increased N intake and subsequently N excretion. Increased N excretion was predicted to outweigh reductions in CH4 through increased formation of nitrous oxide (N2O). Therefore, feeding CDDGS and WDDGS resulted in 6.3 and 9.3% higher GHG intensity (kg CO2 equivalent [CO2e]/kg beef) compared to the control. To reduce the environmental impact, DDGS should not be fed at inclusion levels that exceed N requirements of feedlot cattle.
