Book Effect of Dried Distillers  Grains with Solubles on Greenhouse Gas Emissions from Beef Cattle

Download or read book Effect of Dried Distillers Grains with Solubles on Greenhouse Gas Emissions from Beef Cattle written by Martin Hünerberg and published by . 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.

Book Effects of Feeding Distillers Dried Grains with Solubles to Finishing Swine on Animal Performance  Manure Characteristics  and Odorous Emissions  as Analyzed by Olfactometry  an Electronic Nose  and Gas Chromatography mass Spectrometry

Download or read book Effects of Feeding Distillers Dried Grains with Solubles to Finishing Swine on Animal Performance Manure Characteristics and Odorous Emissions as Analyzed by Olfactometry an Electronic Nose and Gas Chromatography mass Spectrometry written by Amanda Kaye Gralapp and published by . This book was released on 2000 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electronic nose used was an AromaScan A32S (Osmetech, Crewe, UK) with an array of thirty-two semi-conducting polypyrrole sensors. No differences in animal performance were observed (P> .05). A non-significant trend of increasing odor, in terms of odor dilution threshold, with increasing dietary concentration of DDGS was observed (P = .16). Sixteen compounds, primarily non-sulfur protein metabolites, were routinely quantified in room air samples by GC-MS. Using these compounds, an equation was generated to predict odor dilution threshold. Poor prediction capability (R2 = .23) indicates additional analytes require consideration, although repeated occurrence of other analytes in air samples was not evident from GC-MS analyses. Electronic nose evaluation of room air samples was not strongly correlated to olfactometry measures (r = .18). However, the equation developed from GC-MS analyses was capable of predicting electronic nose response to air samples (R2 = .81). The results suggest human panelist responses may be based on detection of compounds not included in GC-MS quantification procedures and not well detected by the electronic nose.

Book Effects of Floor Space and Removal of Corn Distillers Dried Grains with Solubles on Heavy Weight Pig Performance

Download or read book Effects of Floor Space and Removal of Corn Distillers Dried Grains with Solubles on Heavy Weight Pig Performance written by Anne Bonner Lerner and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is comprised of 5 chapters consisting of a study evaluating space allowance and marketing strategies for pigs raised to 160 kg, three experiments evaluating the impact of removing corn distillers dried grains with solubles (DDGS) from finishing pig diets, four studies evaluating the use of medium chain fatty acids (MCFA) as a mitigation strategy for porcine epidemic diarrhea virus (PEDV), and development of a swine-specific undergraduate research program. In Chapter 1, four treatments were evaluated with decreasing space allowance from 1.17 to 0.71 m2/pig with only one final marketing event, plus two treatments with restricted space allowance and four or three marketing events. Increasing space allowance via increased initial pen inventory increased average daily gain (ADG), decreased average daily feed intake (ADFI), and reduced feed efficiency (G:F). Marketing pigs 3 or 4 times improved G:F compared with to the similar treatment with only one marketing event but resulted in similar weight marketed per pen. In chapter 2, pigs were switched from diets containing corn DDGS to corn- and soybean-meal based diets (CSBM) starting at 76 d prior to market. As time consuming CSBM increased, ADG and final BW increased and G:F improved. Average daily feed intake decreased with increasing time after dietary switch to CSBM. Hot carcass weight increased and iodine value decreased with increasing time after DDGS removal from diets. Chapter 3 also evaluated the removal of corn DDGS from finishing pig diets but utilized two seasonal marketing strategies. Regardless of marketing strategy, switching pigs from DDGS to CSBM resulted in increased carcass yield and decreased iodine value, yet live growth performance was marginally impacted. In chapter 4, four experiments were conducted to evaluate the efficacy of applying MCFA to swine feed on detection and infectivity of PEDV. Applying chemical mitigants both prior to and post-PEDV inoculation was effective at reducing PEDV detection via quantitative real time reverse transcriptase polymerase chain reaction (qRT-PCR). When tested individually and in combination and applied before viral inoculation, caproic and caprylic acid appeared to provide the greatest reduction of detectable genetic material. The addition of a 1:1:1 blend of C6:C8:C10 at 0.5% and 0.3% C8 prevented infection in in vivo bioassay. Lastly, chapter 5 presents a model to develop a species-specific undergraduate research program in the context of a swine nutrition program that is currently in use at Kansas State University. This program utilizes both graduate students and faculty to provide mentorship and has several project types that vary in level of student involvement. The program is designed to provide a comprehensive research experience, with an emphasis on including the student in pre- and post-trial activities beyond data collection. A majority of students that complete the undergraduate research program enter graduate or veterinary degree programs upon completion of their undergraduate work and cite undergraduate research as a critical step in their career selection process and professional development.

Book Effects of Dried Distillers Grains with Solubles on Pork Loin Quality and Sow Fat Quality

Download or read book Effects of Dried Distillers Grains with Solubles on Pork Loin Quality and Sow Fat Quality written by Amanda Nicole Gipe and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to determine the effects of dried distillers grains with solubles (DDGS) on pork loin and fat quality. In the first experiment, 1,160 barrows (PIC) were used in a 70-d study to determine the influence of DDGS and glycerol on pork loin and fat quality attributes. Barrows were fed a corn-soybean meal based diet with the addition of selected levels of DDGS (0 or 20%) and glycerol (0, 2.5, or 5%) feed stuffs. Loins from the two heaviest pigs in each pen were removed for evaluation of pork loin and fat quality. Experiment two was a pilot study, in which eight non-pregnant sows were fed either 0 or 50% DDGS with a corn soybean meal based diet for 92-d. In the first experiment, there were no DDGS x glycerol interactions for purge loss %, instrumental color (L*a*b*), visual color, marbling score, drip loss %, visual color, pH, Warner-Bratzler shear force (WBSF), cook loss %, myofibrillar tenderness, juiciness, pork flavor intensity, connective tissue amount, and overall tenderness. There was a DDGS x glycerol interaction (P0.03) for off-flavor intensity. Pigs fed diets with 20% DDGS had higher WBSF values, lower myofibrillar tenderness, lower overall tenderness scores, lower connective tissue scores, and had more off-flavors (P0.05). Loin fatty acid analysis revealed an increase in palmitoleic, linoleic, and eicosadienoic acids (P

Book Analyzing the Utilization and Trade of Distillers  Dried Grains with Solubles

Download or read book Analyzing the Utilization and Trade of Distillers Dried Grains with Solubles written by Maria Celeste De Matteis and published by . This book was released on 2017 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production and consumption of distillers' dried grains with solubles (DDGS), a coproduct of corn-based ethanol, has rapidly grown over the last decade in the United States (U.S.) and lately in other countries that prompt biofuel production, such as Argentina. DDGS has a more concentrated nutritional value relative to traditional feed grains and can be used in feed rations to meet the energy and protein requirements. In the first study, I evaluated the factors that determine the exports of U.S. DDGS, while the second study focused on the effects of the inclusion of DDGS in the feed rations of swine in Argentina. In the U.S., the feed use of DDGS has grown more than threefold between marketing year (MY) 2004/05 and 2014/15 and, over the same period, the demand for U.S. DDGS from global markets has also quickly risen. Therefore, the objective of this study was to identify the determinants of U.S. DDGS exports through a gravity model and develop a baseline of the DDGS exports to major international buyers up to 2020. This baseline was then used to evaluate the impacts of variation in the key determinants on DDGS exports in the future. Results suggest that importers' meat production and consumption, importers' stock of cattle, technical barriers to trade, tariffs, and U.S. ethanol production were influential to U.S. DDGS exports. In the second part of this thesis the potential cost and phosphorus quantity effects of including DDGS in the feed rations on the Argentinean swine industry were analyzed. A conventional feed ration without DDGS and an alternative feed ration including DDGS were studied using cost and phosphorus minimization models for three different growth categories of swine in their growing and finishing growth stages. Results suggest that incorporating DDGS in a swine feed ration can potentially achieve the goals of minimum cost and minimum phosphorus content simultaneously. My assessment also implies that the Argentinean swine industry could benefit in cost savings of up to US $19.21 million and a reduction in phosphorus by five percent if DDGS was fully adopted in the feed rations for all growth categories of swine.

Book Utilization of Distiller s Dried Grains with Solubles in Swine Diets

Download or read book Utilization of Distiller s Dried Grains with Solubles in Swine Diets written by Scott Matthew Williams and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Six experiments were completed to determine factors influencing the use of distillers dried grains with solubles (DDGS) in diets for nursery and finishing pigs. In Exp. 1, 105 nursery pigs were fed corn-soybean meal (SBM) based diets with CP concentrations of 22.5, 25, and 27.5%. Overall ADG, ADFI, and G:F were not affected by increasing CP (P> 0.19). In Exp. 2, 105 nursery pigs were fed excess CP from SBM and DDGS. Overall ADG, ADFI, and G:F for pigs fed the control diet were not different from those fed the high CP treatments (P> 0.12). However, pigs fed the DDGS treatment had lower G:F than pigs fed the corn-soy diet with similar CP content (P 0.04). For Exp. 3, 176 finishing pigs were fed diets with CP concentrations increasing from 12 to 18%. Increasing CP had no effect (P 0.20) on ADG, ADFI, G:F, and hot carcass weight (HCW). For Exp. 4, 180 finishing pigs were fed excess dietary CP from SBM and DDGS. Pigs fed diets with high CP had lower ADG, ADFI, and HCW, but these results were caused by the diet with 40% DDGS (SBM vs DDGS, P 0.001). For Exp. 5, 224 nursery pigs were used to determine the effects of extrusion processing on the nutritional value of DDGS. Overall ADG and ADFI were greater for pigs fed the corn-soy control compared to the DDGS treatments (P

Book The Effects of Feeding Dry Distiller s Grains with Solubles on Ruminal Metabolism  Growth Performance  and Carcass Traits of Feedlot Cattle

Download or read book The Effects of Feeding Dry Distiller s Grains with Solubles on Ruminal Metabolism Growth Performance and Carcass Traits of Feedlot Cattle written by and published by . 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

Book Effects of Drying Distillers Grains Plus Solubles on Feedlot Cattle Performance and Nutrient Digestibility

Download or read book Effects of Drying Distillers Grains Plus Solubles on Feedlot Cattle Performance and Nutrient Digestibility written by Brandon L. Nuttelman and published by . 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.

Book Use of Corn Dried Distillers Grains  DDGS  in Feeding of Ruminants

Download or read book Use of Corn Dried Distillers Grains DDGS in Feeding of Ruminants written by Ewa Pecka-Kiełb and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioethanol is the product of fermentation of starch contained in renewable resources, such as corn, wheat, rye and rice. Depending on the technology used for its production, dried distillers decoction may exist in different forms: dried distillers grain (DDG); dried distillers grain with solubles (DDGS) and high-protein dried distillers grains (HPDDG), as well as wet distillers grain (WDG), wet distillers grain with solubles (WDGS), and high-protein wet distillers grains HPWDG). Research conducted in recent years has demonstrated the possibilities of corn DDG as feed for livestock due to its high content of valuable protein, high calorific value and bioelements. Distillers grain has been used as feed for beef and dairy cattle, sheep, swine and poultry. In case of ruminants, it is important that distillers grain is foodstuff high in ruminal undegradable protein, with beneficial fibre content that does not cause rumen acidosis. DDGS has positive influence on milk yield and its fat and protein content. Research on rumen fermentation has proven that DDGS positively affecs processes in forestomachs: methanogenesis, ammonia emission and volatile fatty acids profile. Reprocessing of agri-food industry by-products may well be an alternative for traditional methods of feeding animals and utilizing valuable nutrients that they contain.

Book Distillers Dried Grain Product Innovation and Its Impact on Adoption  Inclusion  Substitution  and Displacement Rates in a Finishing Hog Ration

Download or read book Distillers Dried Grain Product Innovation and Its Impact on Adoption Inclusion Substitution and Displacement Rates in a Finishing Hog Ration written by Jacinto F. Fabiosa and published by . This book was released on 2008 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study finds that the use of distillers dried grain with solubles (DDGS) as feed is greatly influenced by the development of DDGS products that are available in the market. We find that newer-generation DDGS products have a higher optimal inclusion rate, reaching the maximum allowable rate of 20% for swine, and they have a higher displacement rate of 0.23 for soymeal and 0.93 for corn. Although both traditional and newer-generation DDGS products are primarily used as a corn substitute for energy, it will take only a relatively small change in the price or matrix A (or both) for the newer-generation DDGS to primarily substitute for soymeal for the limiting amino acid, lysine. In contrast, traditional DDGS products have a lower optimal inclusion rate of 7%, and they have a lower displacement rate of 0.75 for corn and 0.08 for soy meal. This product is primarily used as a corn substitute for energy. When traditional DDGS is introduced in a feed ration, total feed cost declines by 2.64%, or a reduction of $0.29 per cwt of feed. This translates into a $2.17 per head savings in feed cost in a feeder-to-finish operation. Using newer-generation DDGS reduces feed cost by 9.88%, or a reduction of $1.08 per cwt of feed, saving feeder-finisher operations $8.06 per head. This study suggests that as a substitute product, the price of DDGS will track the price of both corn and soymeal. It will be more of the former until new-generation DDGS can be used as a primary substitute for soymeal and take a dominant share of the market. Finally, this study clearly points to the critical importance of DDG product innovation to promote widespread and optimal use of DDGS as a feed ingredient, thereby alleviating the food-feed-fuel trade-off.
