Vitamin E Mitigates The Boost In Lipid Oxidation Of Beef Due To Wet Distillers Grains Feeding, Lasika Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Galen E. Erickson
Nebraska Beef Cattle Reports
Beef tenderloin and strip loin steaks were obtained from yearlings (n = 90) fed 0%, 20% and 40% wet distillers grains (DM basis) with or without distillers solubles and vitamin E supplementation. Our aim was to increase the shelf life of case-ready beef by vitamin E supplementation to minimize the potential of lipid oxidation due to wet distiller grains feeding. Data from this study indicate that vitamin E supplementation significantly mitigates the increased oxidation potential of tenderloin and strip loin steaks during retail display due to WDG feeding.

Impact Of A New Direct-Fed Microbial On Intake And Ruminal Ph, Kelsey Rolfe, Nathan Meyer, Galen E. Erickson, Terry J. Klopfenstein, Ryan Mass
Nebraska Beef Cattle Reports
Nine ruminally fistulated steers were used in a metabolism experiment to evaluate the effect of a new direct-fed microbial (DFM) on acidosis. No statistical differences were observed in dry matter intake (DMI). Minimum pH was significantly lower in steers fed the DFM during grain adaptation, resulting in a greater change in ruminal pH and pH variance for steers fed DFM during grain adaptation. However, once steers were on the finishing diet, no differences were detected due to treatment.

Energy Value Of Wet Distillers Grains In High Forage Diets, Brandon Nuttelman, Matt K. Luebbe, Joshua R. Benton, Terry J. Klopfenstein, Leslie Aaron Stalker, Galen E. Erickson
Nebraska Beef Cattle Reports
One hundred sixty crossbred steers were used to determine the energy value of wet distillers grains in high forage diets. By design, steers had similar intakes and gains across treatments. Diets included either wet distillers grains (WDGS) or dry rolled corn, sorghum silage, grass hay and supplement (DRC). Diets were formulated to meet degradable intake protein and metabolizable protein requirements. The energy value of wet distillers grains was calculated using the National Research Council model (1996). In this study, wet distillers grains contained 130% of the energy of dry rolled corn when fed in forage-based diets.

Effects Of Substituting Wet Distillers Grains With Solubles In A Wet Corn Gluten Feed-Based Diet On Finishing Performance, Cody Nichols, Matt K. Luebbe, Galen E. Erickson, Rick Stock, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A finishing study evaluated feeding a wet corn gluten feed (WCGF) ration containing no high moisture corn with varying inclusion levels of wet distillers grains plus solubles (WDGS), as well as a control diet containing 20% WDGS and 20% WCGF. Wet distillers grains with solubles replaced WCGF at 10%, 20%, 30% and 40% of the diet. As WDGS replaced WCGF, feed-to-gain ratio (F:G) decreased linearly. However, two steers developed polioencephalomalacia on the treatment that contained 40% WDGS. Steers fed the control diet containing 40% byproduct had greater average daily gain (ADG) and lower F:G than the average of all WCGF:WDGS …

Nebraska Beef Cattle Reports
Animals were housed in individual pens and fed high quality (11% CP) meadow hay ad libitum daily to evaluate the effect of a beef animal’s physiological state (cow-calf pair vs. dry cow vs. yearling steer) on forage intake. Daily diet samples were composited by week and analyzed. Refusals were collected, composited by week per pen and analyzed. Dry matter intake (DMI) was different among treatments. The results indicate different physiological states or classes of cattle should be considered when calculating forage demand for stocking rate or feeding purposes.
Effects Of Rumensin® And Tylan® In Finishing Diets With Wet Distillers Grains Plus Solubles, Nathan Meyer, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton, Matt K. Luebbe, Scott Laudert
Effects Of Rumensin® And Tylan® In Finishing Diets With Wet Distillers Grains Plus Solubles, Nathan Meyer, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton, Matt K. Luebbe, Scott Laudert
Nebraska Beef Cattle Reports
A total of 3,632 crossbred steers at three different sites (Nebraska, Colorado and Oklahoma) were utilized in a randomized complete block design (RCBD) study. Data were combined for the Colorado and Oklahoma trials. Steers were fed one of five treatments: 1) Traditional corn diet with Rumensin and Tylan (CORN+RT); 2) Wet distillers grains plus solubles (WDGS); 3) WDGS with Rumensin (WDGS+R); 4) WDGS with Rumensin and Tylan (WDGS+RT); and 5) WDGS with expanded dose range of Rumensin (44.4 g/ton) and Tylan (WDGS+HIRT) to evaluate the effects of Rumensin and Tylan in feedlot diets containing WDGS. In WDGS diets, feed-to-gain ratio …
Composting Or Stockpiling Feedlot Manure: Nutrient Concentration And Recovery, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Composting Or Stockpiling Feedlot Manure: Nutrient Concentration And Recovery, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Nebraska Beef Cattle Reports
Manure stockpiled anaerobically or composted aerobically for 111 days was evaluated for nutrient concentration and recovery. Recovery of dry matter (DM) and organic matter (OM) was not different among storage methods. The proportion of organic nitrogen (N) was greater for composted manure while ammonium N was greater in stockpiles. Recovery of N from stockpiled manure was greater than from compost when ammonium N was measured on “fresh” samples and samples dried down to simulate field application. Anaerobic stockpiling of feedlot manure provides a greater amount of N for crops and similar amounts of DM and OM.
Effect Of Dietary Cation-Anion Difference On Intake And Urinary Ph In High Concentrate Diets, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Nathan Meyer
Effect Of Dietary Cation-Anion Difference On Intake And Urinary Ph In High Concentrate Diets, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Nathan Meyer
Nebraska Beef Cattle Reports
Seven experiments evaluated the effect of basal diet and dietary cation-anion difference (DCAD) on urinary and fecal pH, and DMI. Dry-matter intake(DMI) was reduced by DCAD level in dry-rolled corn basal diets but not in diets that included 20% wet distillers grains (WDGS). Urinary pH decreased with DCAD level in all experiments. Fecal pH was not influenced by either DCAD level or basal diet. Altering DCAD in concentrate diets with or without WDGS does impacturinary pH.

Limit Feeding Beef Cows With Bunkered Wet Distillers Grains Plus Solubles Or Distillers Solubles, Luke M. Kovarik, Matt K. Luebbe, Richard J. Rasby, Galen E. Erickson
Nebraska Beef Cattle Reports
An experiment was conducted using 70 cows to evaluate performance when limit limit-fed grain byproducts. Cows in the wet distillers grains plus solubles (WDGS) treatment group and those in the distillers solubles (DS) treatment group were limit fed a diet containing 41% byproduct and 59% cornstalks. The control (CON) treatment consisted of ad libitum intake of 43% brome hay, 34% cornstalks and 23% alfalfa haylage. Cows fed WDGS were heavier compared to those in the DS and CON treatment groups. Average daily gain (ADG) tend¬ed to be greater for WDGS treatment compared to the CON treatment. These data suggest that …
Feeding Distillers Grains And E. Coli O157:H7, Terry J. Klopfenstein, David R. Smith, Galen E. Erickson, Rodney A. Moxley
Feeding Distillers Grains And E. Coli O157:H7, Terry J. Klopfenstein, David R. Smith, Galen E. Erickson, Rodney A. Moxley
Nebraska Beef Cattle Reports
The diet of feedlot cattle may affect the bacterial population in the hindgut, includingE. coli O157:H7. Some research studies have shown a relationship between feeding of distillers grains and E. coli O157:H7 shedding. However, other studies do not show the same relationship. Our evaluation of research indicates feeding distillers grains is not related to 2007 ground beef recalls. Furthermore, interventions such as vaccination are more important than identifying various feedstuffs that may influence shedding.
Using Wet Corn Gluten Feed To Adapt Cattle To Finishing Diets, Taia Huls, Matt K. Luebbe, William Griffin, Galen E. Erickson, Terry J. Klopfenstein, Rick Stock
Using Wet Corn Gluten Feed To Adapt Cattle To Finishing Diets, Taia Huls, Matt K. Luebbe, William Griffin, Galen E. Erickson, Terry J. Klopfenstein, Rick Stock
Nebraska Beef Cattle Reports
A feedlot trial was conducted to determine if wet corn gluten feed (WCGF) instead of forage could be used to adapt cattle to finishing rations and if this is economically feasible. Treatments were applied only during grain adaptation (26 days), and all steers were finished on a common diet (147 days) containing 35% WCGF. Steers adapted using WCGF had greater ADG and lower F:G. Treatment had no effect on carcass quality. Profits were higher for steers adapted to finishing diets using WCGF rather than those adapted with alfalfa hay.

Summary Of Grazing Trials Using Dried Distillers Grains Supplementation, William Griffin, Virgil R. Bremer, Terry J. Klopfenstein, Leslie Aaron Stalker, Lyle Lomas, Joe Moyer, Galen E. Erickson
Nebraska Beef Cattle Reports
A meta-analysis of grazing trials in which cattle were supplemented with dried distillers grains with solubles (DDGS) was conducted to determine effects of supplementation on average daily gain (ADG) and final BW in pasture grazing situations. Additionally, pen studies were evaluated to determine the effects of DDGS supplementation on cattle intake, forage replacement, ADG and final BW. In both the pasture and the pen studies, ADG and final BW increased quadratically with increased level of DDGS supplementation. Feeding DDGS decreased forage intake quadratically; however, total intake for cattle supplemented DDGS increased quadratically with increased level of supplementation.

Feeding Corn Distillers Solubles Or Wet Distillers Grains Plus Solubles And Cornstalks To Growing Calves, Mallorie Wilken, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Nebraska Beef Cattle Reports
A growing study compared the effects of a diet consisting of corn distillers solubles (SOL) to the effects of a diet containing corn wet distillers grains plus solubles (WDGS) when ensiled with cornstalks (stalks). Four levels of SOL and WDGS were fed at 15%, 20%, 25% and 30% of diet DM. The effect of feeding ensiled WDGS and stalks was compared to feeding WDGS and stalks mixed fresh daily at 30% inclusion. WDGS-fed steers were more efficient than those fed solubles. Steer performance also improved with increased levels of byproducts. However, no inter¬action between byproduct and level was observed, except …

Effects Of Feeding High Levels Of Byproducts In Different Combinations To Finishing Steers, Mallorie Wilken, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Nebraska Beef Cattle Reports
A finishing experiment was conducted to determine the effects of feeding wet distillers grains plus solubles (WDGS) and wet corn gluten feed (WCGF) with or without corn on feedlot performance and economics. Six treatment diets were evaluated: 1) 83% corn; 2) 44% WDGS and 44% corn; 3) 33% WDGS, 33% WCGF and corn; 4) 33% WDGS, 33% WCGF and soyhulls; 5) 44% WDGS and 44% WCGF; and 6) 66% WDGS and grass hay. The highest average daily gain (ADG) and lowest feed-to-gain ratio (F:G) were observed with cattle fed 44% WDGS and corn. The poorest ADG and F:G were ob-served …

An Economic Overview Of Ethanol Co-Product Utilization In Nebraska, Josie Waterbury, Darrell R. Mark, Sarah Thoms, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
To better understand co-product utilization, inclusion rates, pricing and storage strategies, Nebraska cattle producers were surveyed regarding their co-product feeding and pricing practices. Although nearly 91% of cattle on feed in Nebraska were being fed ethanol co-products in 2007, many types of co-products were being utilized from both ethanol plants in Nebraska and surrounding states. As illustrated by the price data collected, especially those for wet distillers grains plus solubles, opportunities existed for pricing and storage strategies, although more price variation was present in the data collected from the survey as compared to the prices reported by the Agricultural Marketing …
Hydrogen Sulfide Gas Levels Post Feeding, Sarah J. Vanness, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Hydrogen Sulfide Gas Levels Post Feeding, Sarah J. Vanness, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Dietary sulfur level is associated with hydrogen sulfide gas (H2S) levels in the rumen. These studies quantified H2S levels at different times post feeding with or without added iron (Fe) or copper (Cu) to bind sulfur. In addition, the correlations of ruminal pH measurements to ruminal H2S gas levels were estimated. Correlations between ruminal pH and hydrogen sulfide levels were not large and Fe and Cu did not affect H2S levels.
Ruminal Sulfide Levels In Corn Byproduct Diets With Varying Roughage Levels, Sarah Vanness, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Ruminal Sulfide Levels In Corn Byproduct Diets With Varying Roughage Levels, Sarah Vanness, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Ruminally fistulated steers with wireless pH probes were utilized to quantify ruminal pH plus hydrogen sulfide (H2S) levels produced at different times post feeding and to determine the effect of roughage level in high byproducts diets on hydrogen sulfide production. Because of variation in H2S levels, ruminal pH was not related to high H2S levels. When treatment means were used, pH and H2S levels were highly correlated. We observed lower H2S levels in diets with 7.5% or 15% grass hay compared with no roughage.

Moving Beyond Weight As The Only Predictor Of Breeding Readiness: Using A Breeding Maturity Index, Matthew Stockton, Roger K. Wilson, Richard N. Funston, Leslie Aaron Stalker, Dillon Feuz
Moving Beyond Weight As The Only Predictor Of Breeding Readiness: Using A Breeding Maturity Index, Matthew Stockton, Roger K. Wilson, Richard N. Funston, Leslie Aaron Stalker, Dillon Feuz
Nebraska Beef Cattle Reports
A maturity index (MI) was developed using data from Gudmundsen Sandhills Laboratory to predict a heifer’s optimal size for breeding. It was developed from observable information such as age, feeding regime, pre-breeding, birth and dam weights. The MI was the most precise predictor of actual percentage of mature weight versus using estimates developed from the herd’s estimated average weight or the dam’s mature weight. The MI also was a more accurate predictor of first pregnancy than the typically applied measure.
The Effects Of Breeding Maturity On Dystocia And Rebreeding Of The Primiparous Beef Female, Matthew Stockton, Roger K. Wilson, Richard N. Funston
The Effects Of Breeding Maturity On Dystocia And Rebreeding Of The Primiparous Beef Female, Matthew Stockton, Roger K. Wilson, Richard N. Funston
Nebraska Beef Cattle Reports
Maturity Index (MI) was used in a Probit regression as an explanatory variable of dystocia, where dystocia was used in a Probit regression as an explanatory variable of rebreeding rates of primiparous cows from data collected on replacement heifers from the Gudmundsen Sandhills Laboratory. Dystocia was found to decrease from about 40% to 13% for heifers when the MI increased from 53 to 70, supporting the notion that maturity reduces the incidence of dystocia, resulting in an increase in the second pregnancy rate.
Statistics Used In The Nebraska Beef Report And Their Purpose
Statistics Used In The Nebraska Beef Report And Their Purpose
Nebraska Beef Cattle Reports
The purpose of beef cattle and beef product research at UNL is to provide reference information that represents the various populations (cows, calves, heifers, feeders, carcasses, retail products, etc.) of beef production. Obviously, the researcher cannot apply treatments to every member of a population; therefore, he or she must sample the population. The use of statistics allows the researcher and readers of the Nebraska Beef Report the opportunity to evaluate separation of random (chance) occurrences and real biological effects of a treatment. Following is a brief description of the major statistics used in the beef report. For a more detailed …

Effect Of Wet Distillers Grain Feeding Supplemented With Vitamin E On Case Life Of Beef, Lasika S. Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Gary A. Sullivan, Galen E. Erickson
Nebraska Beef Cattle Reports
Aged (7 and 28 days) strip loins (m. Longissimus lumborum) from 90 yearling steers were used to assess the effect of supplemental vitamin E in diets containing wet distillers grains (WDG) with or without distillers solubles on surface discoloration of steaks during retail display. The greatest negative effects occurred as a result of aging, followed by the presence of solubles and then by the level of WDG. As discoloration increased, the importance of vitamin E in reducing discoloration also increased. Feeding WDG diets supplemented with vitamin E mitigates the surface discoloration of aged beef strip loin steaks during retail …

Nebraska Beef Cattle Reports
In a three-year study, corn-dried distillers grains plus solubles (DDGS) were evaluated as a substitute for forage and nitrogen (N) fertilizer in yearling steers grazing smooth bromegrass in eastern Nebraska. Stocking rate increased with N fertilization and DDGS, and average daily gain (ADG) increased with DDGS. Total gain per acre increased by 53% with N fertilization and 105% with DDGS supplementation. N use efficiency was 139% greater per acre with DDGS supplementation compared to fertilizing with N alone. Feedlot ADG was similar among treatments with steers maintaining their BW advantage through the finishing phase.

Replacing Fertilizer Nitrogen With Dried Distillers Grains Supplement To Yearling Steers Grazing Bromegrass Pastures: Economics And Modeling, Matthew A. Greenquist, Terry J. Klopfenstein, Walter H. Schacht, Galen E. Erickson
Nebraska Beef Cattle Reports
An economic analysis of a three-year study evaluated use of N fertilizer and dried distillers grains plus solubles (DDGS) supplementation to yearling steers grazing smooth bromegrass in eastern Nebraska (Nebraska Beef Report, 2009, pp. 26-28). Costs of gain tended to be lower for cattle on fertilized pastures. Grazing profitability was lowest for cattle on non-fertilized pastures, intermediate for cattle supplemented with DDGS, and highest for cattle on fertilized pastures. The weight advantage (9%) of steers supplemented with DDGS during the grazing period was maintained through the finishing period, leading to greater profitability. Profitability for steers supplemented with DDGS at the …

Cattle Performance And Economic Analysis Of Diets Containing Wet Distillers Grains And Dry-Rolled Or Steam-Flaked Corn, Corineah Godsey, William Griffin, Matt K. Luebbe, Joshua R. Benton, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A finishing study was conducted to determine the effect of utilizing dry-rolled (DRC) or steam-flaked (SFC) corn in diets containing wet distillers grains without solubles (WDG). An interaction between corn processing method and DG level was observed for average daily gain (ADG) and feed-gain ratio (F:G), but not for dry matter intake (DMI). In diets containing DRC, ADG increased quadratically (P = 0.02) as WDG level increased, but no difference was observed in gain when steers were fed SFC diets with increasing level of WDG. Feed efficiency responded quadratically for diets containing DRC, with an optimum WDG inclusion of 20% …
Effects Of Surface Soil Temperature On Daily Water Intake In Feedlot Cattle, Rodrigo Arias, Terry L. Mader
Effects Of Surface Soil Temperature On Daily Water Intake In Feedlot Cattle, Rodrigo Arias, Terry L. Mader
Nebraska Beef Cattle Reports
The relationships among soil surface temperature (SST), soil temperature (ST) (4 inches depth) and daily water intake (DWI) were studied using data collected between 2004 and 2006. The equations obtained through simple and polynomial linear regression were evalu¬ated using data collected during the summer 2007. An overall model (May-October) and a summer model (June-August) were developed. The best fit was reached with the overall model using SST in a quadratic model (r2 = 0.86), whereas the summer model fit linearly with SST (r2 = 0.70). Both models tend¬ed to slightly over-predict DWI (13.5% and 12.5%, respectively).

Effects Of Sorting Cattle By Weight And Time Of Year On Finishing Performance, Carcass Characteristics And Economics, Daniel R. Adams, Matt K. Luebbe, William Griffin, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Sorting steers for three different finishing systems (calf-feds, summer yearlings and fall yearlings) resulted in no differences in performance or average carcass characteristics compared to unsorted steers. Sorting decreased variation in hot carcass weight and number of carcasses over 950 lb. Sorting did not increase profit when calf-feds or fall yearlings were sold live compared to unsorted calf-feds and fall yearlings. However, when sold on a grid basis, sorting did increase profit for summer and fall yearlings.
Level Of Wet Distillers Grains Plus Solubles And Solubles Ensiled With Wheat Straw For Growing Steers, Megan Peterson, Matt K. Luebbe, Richard J. Rasby, Terry J. Klopfenstein, Galen E. Erickson, Luke Kovarik
Level Of Wet Distillers Grains Plus Solubles And Solubles Ensiled With Wheat Straw For Growing Steers, Megan Peterson, Matt K. Luebbe, Richard J. Rasby, Terry J. Klopfenstein, Galen E. Erickson, Luke Kovarik
Nebraska Beef Cattle Reports
A growing study compared wet distillers grains plus solubles (WDGS) and solubles ensiled with wheat straw individually fed to crossbred steers. Four blends of ensiled distillers grain and solubles were used to compare performance on growing calves versus feeding ensiled byproducts alone. Increasing the level of distillers grains in the diet increased average daily gain (ADG) and dry matter intake (DMI). The nonensiled distillers grain treatments had at least equal ADG and feed-to-gain ratio (F:G) compared to the ensiled treatments.
Effect Of Dietary Cation-Anion Difference On Feedlot Performance, Nitrogen Mass Balance And Manure Ph In Open Feedlot Pens, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist, Joshua R. Benton
Effect Of Dietary Cation-Anion Difference On Feedlot Performance, Nitrogen Mass Balance And Manure Ph In Open Feedlot Pens, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist, Joshua R. Benton
Nebraska Beef Cattle Reports
Two experiments were conducted to evaluate the effect of dietary cation-anion difference (DCAD) at two levels (-16 and +20 mEq) on feedlot performance and nutrient mass balance in open feedlots. Decreasing DCAD did not negatively impact cattle performance or carcass characteristics. Feeding negative DCAD diets resulted in lower manure pH in both the winter and summer experiments. Final soil core pH was reduced only in the winter experiment. Percentage of N lost was not influenced by DCAD in either experiment. The decrease in manure pH is likely not enough to reduce the amount of N lost in open feedlot pens.
