This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of five trials were conducted to evaluate grain processing, distiller's grains inclusion in finishing diets, interactions between distiller's grains and dry-rolled corn (DRC) or steam-flaked corn (SFC), efficacy of removing roughage in the presence of distiller's grains and the digestibility of distiller's grains in steam-flaked and dry-rolled corn diets. The first trial was designed to determine the optimum flake density of SFC in beef finishing diets. Diets consisted of corn flaked to densities of 360, 411, or 462 g/L. Observed improvements in mill production would support increasing flake density; however numerical decreases in animal performance offset economic benefits of increased productivity. The second trial was conducted to evaluate optimum levels of sorghum wet distiller's grains in finishing diets. Crossbred yearling steers were fed diets containing DRC or SFC and levels of distiller's grains were 0, 10, 20, or 30% of diet dry matter. Distiller's grains can effectively replaced a portion of the corn in finishing diets, but their nutritional value was greater in DRC diets than in SFC diets. In trial 3, crossbred heifers were fed diets containing SFC with 0% DDG and 15% corn silage (CS), 25% DDG and 15% CS, or 25% DDG and 5% CS. In trial 4, crossbreed heifers were fed diets similar containing DRC or SFC with 0% DDG and 15% CS, 25% DDG and 15% CS, or 25% DDG and 5% CS. Results indicate that roughage levels can be reduced in feedlot diets containing DDG with no adverse effects on performance or carcass quality. The fifth trial was a metabolism study conducted to evaluate the digestibility of DDG in beef cattle. Treatments consisted of DRC with 0% DDG, DRC with 25% DDG, SFC with 0% DDG, and SFC with 25% DDG. There were no significant grain processing by distiller's grain interactions observed in main effects. In conclusion optimum flake density was 360 g/L, feeding distiller's grains has a greater value in DRC diets vs. SFC diets, roughage level and type are important in formulating finishing diets, roughage can be reduced when feeding distiller's grains, and ruminal ammonia, and pH are decreased and ruminal lactate is increased when feeding DDG and SFC.
Book Synopsis Evaluation of Performance Carcass Characteristics, and Ruminal Buffering of Feedlot Cattle Consuming Diets Containing Corn-grain Milling Byproducts by : Paige Rebecca Spowart
Download or read book Evaluation of Performance Carcass Characteristics, and Ruminal Buffering of Feedlot Cattle Consuming Diets Containing Corn-grain Milling Byproducts written by Paige Rebecca Spowart and published by . This book was released on 2020 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeds such as Sweet BranTM (SB) and wet distillers grains with solubles (WDGS) contribute high concentrations of dietary energy and low starch while potentially providing buffering qualities that may improve rumen health and performance. Feeding combinations of SB and WDGS is common but research is limited. This study evaluated the effects of SB and WDGS in the diet alone or in combination on performance, carcass characteristics, ruminal pH, and rumination time of finishing beef cattle. The study was a randomized complete block design using pen as the experimental unit. Steers (n = 455; 373 ± 15.5 kg) were randomly allocated to 48 pens (12 blocks, 4 pens/block) and transitioned over 20 d to 1 of 4 steam-flaked corn-based dietary treatments containing: no byproducts (CON), 20% WDGS (WDGS), 20% SB (SB), or 20% SB and 10% WDGS (COMBO). Within each pen, 2 steers were randomly selected to receive an indwelling ruminal pH bolus to quantify pH of the rumen and a 3-axis accelerometer tag to measure rumination for the first 92 d of the study. Diet samples were collected weekly to determine particle size, NDF concentration, and physically effective fiber (peNDF). Cattle performance (BW, DMI, ADG, G:F) was not different (P = 0.96) through the transition period across all treatments. Overall, final BW, DMI, and ADG were greater (P 0.01) for WDGS, SB, and COMBO than CON. Although overall G:F was not different (P = 0.48), feed cost of gain was greatest (P
Book Synopsis Effects of Drying Distillers Grains Plus Solubles on Feedlot Cattle Performance and Nutrient Digestibility by : Brandon L. Nuttelman
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 Synopsis Effects of Corn Processing, Ethanol and Sugar Beet Byproducts, and Dietary Sulfur on Feedlot Health and Finishing Performance by : Cody A. Nichols
Download or read book Effects of Corn Processing, Ethanol and Sugar Beet Byproducts, and Dietary Sulfur on Feedlot Health and Finishing Performance written by Cody A. Nichols and published by . This book was released on 2012 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four finishing studies were conducted to optimize the use of ethanol and sugar beet byproducts in finishing diets containing dry rolled corn (DRC), steam flaked corn (SFC), or a combination of both. Data are limited for feeding combinations of corn processed by different methods (DRC and SFC) fed with wet distillers grains with solubles (WDGS). Also, limited data are available for feeding different levels of beet pulp in corn based adaptation and finishing diets. Lastly, the relationship between dietary fiber and sulfur (rumen degradable; RDS and rumen undegradable) and their impact on feedlot health is not well understood. Therefore, our objectives were to 1) determine the effects of feeding different ratios of DRC and SFC in diets that contain 35% (DM) WDGS on finishing performance and carcass characteristics 2) evaluate the effects of feeding different levels of beet pulp in combination with DRC or SFC, 3) compare grain adaption programs using beet pulp to a traditional grain adaption program with alfalfa hay on finishing performance and carcass merit and 4) determine the relationship between dietary S (rumen degradable and rumen undegradable), neutral detergent fiber and polioencephalomalacia (PEM). A WDGS x corn processing ratio interaction (P = 0.03) was observed for G:F. Cattle fed diets containing no WDGS with SFC as the sole source of corn had 11% greater G:F (0.189, P 0.01) compared to steers fed all DRC diets with no WDGS (0.170). As SFC replaced DRC in diets containing no WDGS, G:F increased quadratically (P 0.01). A positive associative effect in G:F was observed as SFC replaced DRC in diets with 0% WDGS; however G:F was not impacted by corn processing in diets containing 35% WDGS. Final BW, DMI, and ADG decreased linearly (P

Book Synopsis Impact of Ethanol Process Changes on Distillers Grains for Beef Cattle by : Shelby A. Garland
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.
Book Synopsis Effects of Feeding Distillers Grains Throughout a Yearling Heifer Beef Production System on Meat Quality Attributes and Effects of Omnigen - AF with Ractopamine Hydrochloride on Animal Performance and Beef Carcass Characteristics of Feedlot Steers by : Kelby M. Sudbeck
Download or read book Effects of Feeding Distillers Grains Throughout a Yearling Heifer Beef Production System on Meat Quality Attributes and Effects of Omnigen - AF with Ractopamine Hydrochloride on Animal Performance and Beef Carcass Characteristics of Feedlot Steers written by Kelby M. Sudbeck and published by . This book was released on 2014 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heifers (n = 229; 225 kg ± 2) were used in a 2 x 2 x 2 factorial to determine the effects of longterm exposure to corn distillers grains plus solubles (DGS) on meat quality characteristics. Factors included supplementing 0.91 kg (LW) or 2.3 kg (HW) modified DGS (MDGS) while grazing corn stalks; 0.6% BW dry DGS (SS) daily or none (NS) during summer grazing; and finishing diet containing 40% wet corn gluten feed (CGF) or 40% MDGS (DGF) on a DM basis. An interaction was observed within CGF for discoloration, with SS increasing discoloration 30%; but no differences between SS or NS from DGF cattle. Discoloration scores for DGF increased compared to CGF d 6 - 7 and d 4 - 6 for steaks aged 7 and 21 d, respectively. Supplementing with DGS did not further reduce the color stability of retail beef of DGF finished cattle; however, DGS supplementation prior to finishing can affect beef quality when DGS are not included in the finishing diet. In the second study, crossbred steers (n = 336) were utilized in a 2 x 3 factorial evaluating duration of OmniGen – AF supplementation (0, 28, or 56 d) at 4 g / 45.5 kg BW and supplementation of ractopamine hydrochloride (RAC) at 300 mg/ steer daily for the last 28 days of finishing or no supplementation. No Omnigen – AF by RAC interaction or OmniGen –AF effects were observed for any feedlot performance or carcass characteristics measured. Supplementing RAC increased ADG 0.5 kg, increased FBW 10.0 kg, and increased LM area 0.9 cm2 compared to NORAC.

Book Synopsis The Effects of Feed Additives in Beef Finishing Systems and the Effect of Rumen Degradable Protein Supplementation in Corn Residue Grazing Systems with the Use of Distillers on Growth Performance by : Robert Michel Jones
Download or read book The Effects of Feed Additives in Beef Finishing Systems and the Effect of Rumen Degradable Protein Supplementation in Corn Residue Grazing Systems with the Use of Distillers on Growth Performance written by Robert Michel Jones and published by . This book was released on 2017 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: One receiving trial evaluated the effect of the feed additive monensin (trade name: Rumensin) on steer growth performance in the receiving period while evaluating the effects of two receiving vaccinations on morbidity and mortality of newly received calves. No differences were observed in growth performance, morbidity rate or mortality rate between treatments for the first 28 d of receiving. A finishing trial evaluated the effect of the feed additive ractopamine hydrochloride (trade name: Optaflexx) on feedlot growth performance and carcass characteristics of crossbred yearling steers fed to differing degrees of finish. Feeding ractopamine hydrochloride at 300 mg improved ADG, G:F, and HCW regardless of days on feed (i.e., degree of finish). A growing trial evaluated the performance effects of grazing steers on corn residue supplemented with modified distillers grains plus solubles (MDGS; 1.4 or 2.3 kg/d) with or without urea (0 or 0.05 kg/d). No differences were observed in growth performance suggesting that supplemental urea is not necessary when supplementing at least 1.4 kg MDGS to steers grazing corn residue..

Download or read book Treatment and Standardization of Fiberous By-products for Finishing Beef Cattle written by Wesley Wayne Gentry and published by . This book was released on 2016 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cereal grain production and the wet and dry milling industries have yielded a plentiful supply of fibrous by-products for use in livestock production. These by-products can be treated both chemically and physically to alter their digestibility, and effects on animal performance and rumination behavior. Three experiments were conducted to evaluate the treatment of fibrous by-products in steam-flaked corn (SFC)-based diets on in situ digestibility, animal metabolism, animal performance, carcass characteristics, and rumination behavior. Experiment 1 utilized three ruminally cannulated steers (621 ± 3.6 kg of BW) to evaluate in situ digestibility of calcium hydroxide (CH) treated corn stalks and sorghum wet distillers grains plus solubles (SWDGS). Treatments included: untreated SWDGS (S), CH treated SWDGS (2.67 % DM basis; S-CH), untreated corn stalks (C), and CH treated corn stalks (C-CH). All treatments were placed at once in the ventral rumen space three ruminally cannulated steers and incubated in the rumen for 0, 6, 12, 24, 36, and 48 h. Effective ruminal degradability (ERD) of DM was greater (P

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 Synopsis Effects of Ruminally Degradable Nitrogen in Diets Containing Wet Distiller's Grains with Solubles and Steam-flaked Corn on Feedlot Cattle Performance and Carcass Characteristics by : Christian Ponce
Download or read book Effects of Ruminally Degradable Nitrogen in Diets Containing Wet Distiller's Grains with Solubles and Steam-flaked Corn on Feedlot Cattle Performance and Carcass Characteristics written by Christian Ponce and published by . 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.
