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.

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 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Crossbred yearling steers (n = 144 initial BW 367 ± 18.46 kg) were randomly allotted by BW to a randomized complete block design with a 2x3 factorial treatment arrangement to 1) assess the impact of supplementing dried distiller grain with solubles (DDGS) while grazing late season forage for 90 d and 2) the impact of a short feeding period on animal performance, carcass characteristics and meat quality traits. Treatments consisted of DDGS supplementation during grazing (0 or 1% of BW as DDGS; DM basis) and finishing days on feed (DOF;75, 100, 125). During grazing supplemented cattle had greater (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.

This book was released on 2015 with total page 115 pages. Available in PDF, EPUB and Kindle. 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.

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.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Residual feed intake (RFI) is a measurement of feed efficiency and is becoming a popular trait used in genetic selection. This study evaluated the effects of RFI classification on beef cattle performance, carcass and meat quality and its repeatability between growing and finishing phases of production. Cattle were managed on two different nutritional management regimens consisting of finishing on a high grain diet or backgrounding cattle prior to being finished on a high grain diet. Extensive RFI reranking occurred between production phases. Reranking was positively correlated with longissimus muscle area but did not influence other carcass and meat quality parameters. Growing phase RFI classification had a minimal effect on carcass traits, while low RFI classified steers in the finishing phase produced bigger ribeyes. High RFI steers produced juicier and more tender beef compared to low RFI steers assessed using taste panel and consumer evaluations.

This book was released on 2015 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feeding high levels of wet distillers grains plus solubles (WDGS) increases polyunsaturated fatty acid (PUFA) levels in beef. Perhaps, WDGS in feedlot diets increases PUFA concentration in the SR membrane, thereby altering membrane integrity, resulting in more rapid calcium leakage and improved tenderness. Feeding antioxidants may mitigate such effects. In the first study, effects of feeding 50 % WDGS on SR membrane composition, free calcium concentration and tenderness were studied. The SR membrane from steers fed WDGS were more tender, had higher free calcium concentration, had more PUFA, more phosphatidylcholine (PC), less phosphatidylethanolamine (PE) and less total phospholipids when compared to SR membrane from steers fed corn-only (P

This book was released on 2016 with total page 215 pages. 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

This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.
