This book was released on 2014 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: As ethanol production continues to increase, so does the use of dried distiller's grains with solubles (DDGS) in swine diets. The effects of high concentrations of DDGS on growing/finishing pigs has caused problems with growth performance, carcass characteristics, fat quality, and processed meats. This is due to the high fiber content and elevated levels of unsaturated fats in of the diet. Since DDGS fiber is a complex carbohydrate pigs cannot digest, the use of carbohydrases to improve growth performance is reasonable. Carbohydrase enzymes may be able to help improve fat quality, however the effect of carbohydrase enzymes on fat quality has not been thoroughly researched and the effect on processed pork products has not been examined. Therefore, the objective of these experiments was to evaluate the effects of two carbohydrase enzymes on growth performance, carcass traits and quality, fat quality, and two types of processed pork products (fresh bratwurst and ring bologna) from pigs fed a diet containing 30% DDGS. Pigs were fed a one of two corn/soybean meal/DDGS diets, the only difference being the enzyme group received a combination of two carboghydrase enzymes at the expense of corn. While the pigws were alive growth performance was documented. After the pigs were humanely slaughtered, carcass traits and quality where documented. There was no effect of enzymes on any growth performance or carcass values recorded except for a slight change in the color of the loin. There was no effect of diet on the fat quality. There was a minimal effect on the ring bologna. The biggest influence of enzyme was on the bratwurst. Enzymes had a negative effect on bratwurst quality over time on some qualities. However, other qualities of the bratwursts were positively affected. These results suggest carbohydrase enzymes in a diet containing 30% DDGS does not significantly affect growth performance or carcass characteristics of growing/finishing barrows. However, they do indicate that more research is needed to better understand the effect of carbohydrase enzymes on fat quality and more importantly, processed pork quality.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the effects of corn byproducts high-protein died distillers grain (HP-DDG), and dried distillers grain with solubles (DDGS), and branched chain amino acids (BCAA) on the growth performance and meat quality of pigs. The first study evaluated the combined effect of dietary level of DDGS and HP-DDG on the growth performance of wean-finish pigs and carcass and pork quality characteristics. This study demonstrated that DDGS can be included at up to 30% in diets (without HP-DDG) without compromising growth performance of wean-to-finish pigs. However, growth performance was increasingly compromised at higher inclusion levels of both co-products and belly firmness was negatively affected by increasing levels of both DDGS and HP-DDG. A second experiment was designed to define the minimum CP level and whether non-essential amino acids become limiting in low crude protein diets for late finishing pigs. The results of this study demonstrated that late finishing pigs can be fed diets with 9.76% crude protein level supplemented with 0.32 % L-Lys HCL and other essential amino acids without affecting growth rate and that non-essential amino acids were not limiting in the low crude protein diets evaluated. A third study was designed to recreate the negative effects on growth performance of feeding diets with 30% HP-DDG inclusion level and to test if the negative effect of feeding high HP-DDG levels on growth performance can be reproduced by adding excess branched chain amino acids (leucine, isoleucine, and valine) to standard corn-soybean meal based diet. The results show that the reduction in the growth rates of growing pigs fed diets with 30% HP-DDG inclusion levels may be due to the dietary excesses of leucine present in diets with HP-DDG at 30% inclusion levels. The same effect was not present in finishing pigs. In general, growth performance and belly quality are compromised at higher inclusion levels of both HP-DDG and DDGS. The results of the last studies indicate that leucine level may play an important role on the reduction of the growth performance of pigs fed 30% HP-DDG inclusion levels.

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.

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 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A feedlot trial (Exp. 1) was conducted to evaluate the impact of removing modified distillers grains plus solubles (MDGS) on performance and carcass characteristics. Cattle with MDGS removed on either d 79 or d 43 had reduced final BW, DMI, and ADG. Cattle with MDGS removed on d 43 were 5% less efficient than cattle fed 20% MDGS throughout the entire 124-d feeding period. Cattle fed 20% MDGS throughout the whole feeding had the greatest HCW and LM area. There were no differences in backfat and marbling scores among treatments, and no differences in percent of abscessed livers. In conclusion, removing MDGS from finishing diets had a negative impact on cattle performance compared with feeding 20% MDGS continuously throughout the entire finishing period. In addition, another feedlot trial (Exp.2) and a metabolism trial (Exp.3) were conducted to evaluate the effect of 0%, 15%, or decreasing inclusions (30-15-0%) of MDGS with high- or low-quality roughage on ruminal pH, rumination behavior, and finishing cattle performance, and carcass characteristics. In Exp. 2 there was an interaction between roughage source and MDGS inclusion observed for DMI. No other significant interactions were observed. Cattle fed the diet with 0% MDGS inclusion had reduced HCW, DMI, ADG and 12th rib fat thickness, and poorer G:F compared to cattle fed diets containing MDGS. Cattle fed decreasing inclusions of MDGS (30-15-0%) had lower DMI, ADG and tended to have lighter HCW compared to cattle fed 15% continuously; however, G:F was not affected compared to when distillers was fed at 15% continuously. Cattle fed 15% MDGS had greater marbling score than 0% inclusion and tended to be greater than cattle fed 30-15-0% MDGS. Cattle fed 12% silage consumed less, gained the same, and had greater G:F than cattle fed 6% stalks. These data suggest that feeding 15% distillers was not enough to offset lower quality roughage (stalks) compared to silage as roughage source. In Exp.3 an interaction between roughage source and MDGS inclusion was observed for pH magnitude, pH variance, and DMI. Cattle fed 0% or 15% MDGS with either corn silage or corn stalks had similar average rumen pH. Cattle fed corn stalks had greater maximum and minimum rumen pH. No significant differences were observed for rumination behaviors. In conclusion, smaXtec pH probes and CowManager animal behavior tags need further validation for cattle fed high-concentrate diets.

This book was released on 2020 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marbling and tenderness in meat are some of the most impactful factors for the consumer eating experience. The cause of the relationship between marbling and tenderness is still unresolved. This study was conducted to evaluate the effects of feeding different types of processed corn, with or without distiller grains on oxidative stress, and how that relates to tenderness and shelf life of beef steaks of differing quality grades. Steers (n= 240) were finished on dry rolled corn (DRC), DRC + 30% dried distillers grains (DDGS), steam flaked corn (SFC), or SFC + 30% DDGS. Cattle were fed 10 per pen. Only pens with both upper 2/3 Choice and Select-grade carcasses were sampled, with a goal of two (and a minimum of one) of each grade per pen. Three pens per treatment met the selection criterion and 36 carcasses were chosen (21 upper 2/3 Choice and 15 Select). Both strip loins were collected from each carcass, halved, and aged for 2, 9, 16, or 23 d. After aging, steaks were placed under retail display for 7 d. Subjective discoloration and instrumental color (L*, a*, and b*) were determined daily, and WarnerBratzler shear force (WBSF), slice shear force (SSF), and lipid oxidation (thiobarbituric acid reactive substances; TBARS), were measured after 0 and 7 d of retail display. Fatty acid profile, proximate composition, sarcomere length, sarcoplasmic calcium, pH, proteomic analysis, isoprostane content, and troponin-T (Tn-T) degradation of the lean were obtained. No impacts on sarcomere length, pH, sarcoplasmic calcium, and isoprostane content were found (P> 0.05). The difference in proximate composition was due to fat content between quality grades (P

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 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A high moisture corn/soybean meal-based finishing ration was used to examine the effects of roughage source (corn silage, alfalfa hay), level of dietary roughage (8, 16, 24%), and ractopamine supplementation (none, Optaflexx) on growth performance, carcass traits, and beef quality for finishing 108 steers and 24 heifers (initial BW = 308 kg). Cattle were allocated by gender to 12 management regimen subclasses. Optaflexx (trade name for ractopamine hydrochloride) was fed over the last 28 d on feed with cattle marketed after common days on feed. Growth performance (ADG, feed intake, and feed efficiency) and carcass traits were assessed on an individual animal basis. A primal rib and semitendinosus (ST) muscle from each animal were processed at the University of Guelph Meat Laboratory for carcass and meat quality evaluations. Tenderness was determined using shear force assessment of product aged 7, 14, and 21 d. Average daily gains were similar (P > 0.27) across main effects while use of corn silage as the roughage source decreased (P 0.001) dry matter intake and improved (P 0.001) feed efficiency compared to feeding alfalfa hay. Roughage level and beta agonist supplementation did not affect (P 0.13) dry matter intake or feed efficiency. When the last 28 days on feed were examined, Optaflexx supplementation increased (P 0.001) weight change, ADG, and improved feed conversion, while DMI remained unchanged (P 0.373). Carcass traits including hot carcass weight, grade fat, longissimus muscle area, marbling, and body composition as assessed by rib dissection (% lean, fat, bone) were not affected (P 0.14) by roughage level, source, or use of Optaflexx. Fat partitioning and liver abscess scores were unaffected (P > 0.09) by source and level of roughage fed, and use of Optaflexx. Source and level of dietary roughage did not affect color (P > 0.21) or shear force (P > 0.20) values for longissimus (LM) and semitendinosus (ST) steaks. Lower DMI and better feed conversion can be achieved using corn silage as the roughage source, while inclusion of up to 24% roughage in finishing diets may not negatively impact gains, carcass characteristics or beef quality. Beef producers may be able to increase amounts of roughage in the diet to lower cost of production without compromising growth performance and carcass and meat quality.

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.

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.

Book excerpt: Three methods of forage-finishing (pasture, silage, hay) for beef cattle were used to evaluate growth performance, carcass traits, meat quality, and fatty acid composition relative to grain-finished beef. Two hundred steers (100 Angus, 100 Hereford) were equally allocated (based on size) to 2 locations, evaluating alfalfa or grass forages as alternatives to grain. Growth performance and carcass traits were greater for grain-finished steers. Forage-finishing increased (P 0.02) concentrations of alpha-linolenic acid and total omega-3 fatty acids vs. grain-finishing. A trained taste panel found no difference (P 0.05) in tenderness between forage-and grain-finished beef. Beef flavour intensity was greater (P
