Book excerpt: These studies analyzed the effects of feeding distillers grains on the shelf life of cooked and raw ground beef, and how the addition of postmortem or dietary antioxidants impact shelf life. For study one, cattle were assigned to backgrounding diets containing low or high concentrations of wet distillers grains (WDGS) and either corn gluten feed or modified wet distillers grains (MDGS) during finishing. For study two, cattle were fed one of five finishing diets; corn, wet distillers grains (WDGS), WDGS + vitamin E, WDGS + Ethoxyquin/TBHQ, or WDGS + vitamin E + Ethoxyquin/TBHQ. Shoulder clods from each dietary treatment were ground and lean, fat, and composite samples were taken for fatty acid analysis. Patties were overwrapped for retail display and analyzed for lipid oxidation, discoloration and objective color. Cooked beef links were manufactured with salt and phosphate. Links from the first study contained different concentrations of rosemary and green tea extract. Beef was stuffed into links, cooked, and lipid oxidation was measured throughout refrigerated or frozen storage. For study one, there were no differences in lipid oxidation of patties, yet ground beef from heifers finished with MDGS discolored faster than beef from cattle finished on corn gluten feed. Increased lipid oxidation in beef links occurred when cattle were fed distillers grains during backgrounding or finishing but antioxidants reduced lipid oxidation similarly regardless of concentration. For study two, ground beef patties showed no dietary differences for instrumental color, only increased percent discoloration over time. All ground beef TBARS increased over time, and supplementation of vitamin E resulted in lower TBARS values than corn after 2 d of retail display. An increase in PUFA and C18:2 was observed in lean and composite fatty acids in WDGS versus corn-finished cattle. Both dietary and postmortem antioxidants were effective at extending shelf life in ground beef from cattle fed distillers grains. Additionally, the effect of feeding distillers grains on shelf life varies depending on when distillers grains was supplemented.

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

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.

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 excerpt: The projected expansion in U.S. corn-based ethanol production over the next several years has created concern that large surpluses of distillers grains may result. Most of the distillers grains currently being produced are consumed by the domestic livestock and poultry industries, especially the beef industry. A recent study by the Center for Agricultural and Rural Development projects that the U.S. ethanol industry could produce between 40 million and 88 million metric tons of distillers grains (dry matter basis) per year by 2011. The proportion of these distillers grains that would need to be consumed by the beef industry to prevent surpluses poses questions about how much distillers grains can be included in beef rations, the effects of feeding distillers grains on beef quality, and how current consumption patterns are likely to change as production of distillers grains increases. As more data from feeding trials have become available, a better understanding of the benefits and effects of feeding distillers grains is emerging. In this paper, we use results from a recent USDA producer survey about co-product use in beef production to project how current patterns of use are likely to change as the volume and availability of distillers dried grains increases. We then review recent results from feeding trials using distillers grains in beef rations, including nutritional value and effects on live animal performance and beef quality. Finally, we discuss some of the new technologies being used to improve distillers grains as a ration ingredient and present some general conclusions.

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.

This book was released on 2018 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to evaluate the effects of feeding high protein corn distillers grains on fresh beef quality. Steers (n=300) were fed one of five diets (6 pens with 10 head/pen): a corn control, 40% high protein dry distillers grains plus solubles (HP-DDGS), 40% dry distillers grains plus solubles (DDGS), 40% wet distillers grains plus solubles (WDGS), or 40% bran plus solubles (Bran). Eighteen Choice carcasses (3 head/pen) were randomly selected within each treatment (n=88). Strip loins were aged for 2, 9, or 23 d, after which steaks were placed under retail display conditions for 0, 4, or 7 d. Dietary treatment had no effect on tenderness within each aging period (P > 0.05). After 7 d of retail display, following all aging periods, steaks from cattle fed HP-DDGS had the greatest discoloration except for DDGS and Bran after 23 d (P

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objective of this dissertation was to test different inclusion rates of dried distillers grains with solubles (DDGS) with or without enzyme supplementation. Study one was conducted to test DDGS at 0, 5, 10, 15, 20, or 25% on egg production parameter (24 through76 wk). As DDGS increased, egg wt. decreased during Phase I. However; no difference in egg wt. was observed during Phase II. Yolk color linearly increased with increasing DDGS level. Nitrogen and P retention increased as DDGS increased. Nitrogen and P excretion decreased with increasing DDGS. Study two was conducted to test DDGS inclusion of 0, 2.5, 5.0, 7.5, 10.0, or 12.5% in pullet chicks from day-old to 16 wk and their effect on growth performance. Average feed intake and overall pullet weights were similar. As DDGS increased, BW increased only in 14, 15 and 16 wk. Study three was conducted to test the effect of 5 levels of DDGS (0, 10, 20, 30 or 40%) and two levels of Allzyme SSF enzyme (0, 0.02%) in a 5 X 2 factorial arrangement on egg production parameters. Diets containing the enzyme at 0.02% had nutrient credit of 75 Kcal/kg ME, 0.1% Ca and 0.1% available P. No significant interaction effect for egg production parameters. Feed intake and egg production were similar during Phase I & II. During Phase I and II, egg mass was decreased as DDGS increased. There was no difference in interior egg quality. Specific gravity decreased in Phase II as DDGS increased. Whereas, a linear increase in specific gravity as the enzyme in Phases I and II increased. Yolk color increased with increasing DDGS. A linear increase in N and P retention was observed as DDGS increased. In summary, our results indicated that feeding DDGS to laying hens and pullets is possible at higher inclusion rates if attention is given to AA balance and availability. Allzyme SSF enzyme improved N and P digestibility and assisted in recouping a 75 kcal/kg ME.
