Book Description
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 Description
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.

Book Description
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

Book Description
The objective of this study was to determine the effects of Wet Brewer's Grains (WBG) on the growth performance, carcass performance, and meat quality of finishing cattle. Twenty-four (n=24; 12 heifers -- 303kg, 12 steers -- 346kg) calves of Simmental-Angus genetics were utilized. Calves were paired by sex, blocked by BW within sex in a 2 x 2 factorial arrangement with three replications per treatment, and fed for 140d. Control diets were a conventional corn silage -- shelled corn finishing-diet. Experimental diets modeled the control diet with the inclusion of WBG on a thirty-percent DM basis. Cattle were visually appraised by an industry procurement agent for degree of finish. Finished cattle were transported 160km for slaughter under USDA-FSIS inspection. Primal ribs (IMPS #1103) were obtained and transported to ISU's Meat Lab. Ribeye steaks (IMPS #1112) were fabricated from the ninth -- eleventh ribs for further meat quality analyses. Statistical analysis was modeled in a two-way fixed ANOVA utilizing the MIXED procedure of SAS. No differences were observed in Total Gain and ADG between diets respectively (P = 0.6919). Average Daily Feed Disappearance (ADFD) increased in WBG calves (P 0.0001). Decreases in G:F were observed in WBG calves (P = 0.0121). No differences were observed in HCW, YG, or QG respectively (P 0.05). No differences were observed in Warner-Bratzler Shear Force, Package Purge, or Cook Loss measurements (P > 0.05). This data indicates WBG inclusion supports growth performance, carcass performance, and meat quality of finishing cattle similar to a conventional finishing diet.

Book Description
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 Description
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.

Book Description
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 Description
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.
