Book excerpt: Ethanol plants are centrifuging off oil from the thin stillage stream as it has added market value currently. The impact of oil removal on cattle performance has been minimally researched. Thus four trials, one growing, one digestion, and two feedlot, were designed to determine the energy and feeding value of de-oiled distillers grains in beef cattle diets.In growing cattle diets, diet concentration of modified distillers grains plus solubles (MDGS) impacted cattle performance more than oil content. Ending BW, ADG, and G:F did not differ between cattle fed de-oiled or full fat MDGS, however cattle fed de-oiled MDGS had lower DMI than those fed full fat MDGS. No significant differences in fiber digestibility were observed between de-oiled and full fat MDGS treatments. The energy value of de-oiled MDGS in growing cattle diets was calculated to be 124% the value of corn.In finishing steer diets, increasing diet concentrations of de-oiled MDGS increased G:F. However, decreasing MDGS fat content from 12.0% to 7.2% decreased steer performance by 3.4%. No significant interactions were observed when increasing concentrations of de-oiled wet distillers grains plus solubles (WDGS) were fed with steam flaked (SFC) or dry rolled corn (DRC). Comparison of steer performance when de-oiled and full fat WDGS are fed in SFC and DRC diets resulted in no significant differences also.In growing and finishing diets small differences in cattle performance have been observed. Energy values for distillers grain in growing diets are still high with no improvements in fiber digestibility being observed. In finishing diets where distillers grains were fed at 30-35%, de-oiled distillers grains have 89% the feeding value of full fat distillers grain.

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 2016. 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

Book Synopsis Dried Distillers Grains Plus Solubles as a Protein and Energy Supplement for Beef Cattle by : Joel Blaine Corners

Download or read book Dried Distillers Grains Plus Solubles as a Protein and Energy Supplement for Beef Cattle written by Joel Blaine Corners. This book was released on 2004. Available in PDF, EPUB and Kindle. Book excerpt: The beef industry is in a constant search for new feedstuffs to be used in the production process. This occurs for several reasons. Nutritional support of gain in growing beef cattle needs to, at minimum, match improvements realized in the genetic capability for growth. Feed costs constitute one of the largest beef production costs and economics has dictated that feed cost per kilogram of gain be reduced to remain competitive in the world market. Manufacturing of goods for human consumption has created numerous by-products with little economic value for human use. Dried distillers grains with solubles (DDGS), a by-product of ethanol production, represents a product which could be used as a replacement for soybean meal (SBM) in cattle rations. A national need for fuel-grade ethanol has driven dramatic increases in its production and subsequent increases in DDGS supply. The state of Missouri has been targeted as an area for development of ethanol production. The by-product of the process, DDGS, is high in protein, digestible fiber, and lipid content. This makes it a potential Nitrogen and energy source for ruminant rations. A series of experiments was conducted to evaluate the impact of DDGS as a protein and energy source in beef cattle. We compared DDGS and SBM in growing heifers consuming corn-silage, soyhull, and corn-based diets to evaluate the performance and cost-effectiveness of the two supplements. Similar dietary N levels were evaluated. Inclusion of DDGS in the diet resulted in increased final weight, ADG, DMI, and lower cost of gain as compared to heifers consuming SBM. Grazing is utilized in a large portion of Missouri cattle production, with summer generally requiring supplementation. A study was conducted which evaluated increasing levels of DDGS for heifers grazing tall fescue. Performance criteria were evaluated for animals receiving 0.45, 0.91, or 1.36 kg DDGS and a 0.1 kg soyhull negative control. Average daily gain was quadratically improved as level of DDGS in the diet was increased, with 0.91 kg DDGS providing the greatest ADG. Intake of forage DM and cost of gain were not affected by treatment. The final experiment examined the post-ruminal amino acid flow of mature steers consuming timothy hay and supplemented with DDGS, SBM, a SBM/DDGS blend, or negative control. Supplementation increased duodenal flow of total essential and non-essential AA, while Met, Leu, and Trp were linearly increased by greater inclusion of DDGS in the diet. Dried distillers grains with solubles appears to be a valid replacement of SBM in highforage growing diets.

This book was released on 2017. 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..
