The Economic Impact Of Feeding Wet Corn Co-Products In Nebraska, Josie A. Waterbury, Darrell R. Mark, Richard K. Perrin Perrin
The Economic Impact Of Feeding Wet Corn Co-Products In Nebraska, Josie A. Waterbury, Darrell R. Mark, Richard K. Perrin Perrin
Nebraska Beef Cattle Reports
Isoquants that illustrate combinations of various inputs to produce a given level of output were estimated for wet corn co-products using UNL cattle feeding trial data and applied to actual producer data. Producer economic benefits from feeding wet co-products compared to corn were calculated. Although the combined producer savings from all three wet co-products totaled nearly $39 million, this value was not net of all cost differences between co-products and corn, including transportation, storage, and handling costs.

Supplementing Dried Distillers Grains To Growing Calves On Smooth Bromegrass Pastures, Andrea K. Watson, Matt K. Luebbe, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson, Walter H. Schacht
Nebraska Beef Cattle Reports
Steers supplemented daily with dried distillers grains with solubles (DDGS) on non-fertilized smooth bromegrass pastures gained 1.9 lb/day compared to 1.46 lb/day for cattle on both fertilized and non-fertilized pastures. The fertilized and supplemented treatments were stocked at equal densities, and the non-fertilized pastures were stocked at 69% the density of the other two treatments. At a lower stocking rate, the non-fertilized pastures showed poorer forage production, but equal cattle performance compared to the fertilized pastures. The supplemented pastures showed slightly decreased forage production compared to the fertilized pastures, but at the same time showed increased cattle performance. Each lb …
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, researchers cannot apply treatments to every member of a population; therefore, they must sample the population. The use of statistics allows researchers 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 description of the expectations …
Wet Distillers Grains Diets Supplemented With Vitamin E Affect Sensory Attributes Of Beef M. Longissimus Lumborum, Lasika S. Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Galen E. Erickson
Wet Distillers Grains Diets Supplemented With Vitamin E Affect Sensory Attributes Of Beef M. Longissimus Lumborum, Lasika S. Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Galen E. Erickson
Nebraska Beef Cattle Reports
The effects of feeding 0% or 40% wet distillers grains plus distillers solubles (WDGS) with or without vitamin E (E) supplementation on sensory attributes (tenderness, juiciness, connective tissue content, and off-flavor intensity) of 7-day and 28-day aged beef strip steaks during retail display were investigated by a trained panel. Feeding WDGS or E did not influence tenderness, juiciness, or connective tissue ratings. However, feeding WDGS significantly increased the off-flavor intensity of 7-day aged beef following retail display. Feeding WDGS increased the incidence of livery off-flavor. The protective ability of vitamin E supplementation against livery flavor production was significant in beef …

Lipid And Ndf Analysis Of Ethanol Byproduct Feedstuffs, Virgil R. Bremer, Crystal D. Buckner, Andrew W. Brown, Timothy P. Carr, Ruth M. Diedrichsen, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A newly developed biphasic feed lipid extraction procedure has increased accuracy relative to Goldfisch ether extraction, especially for condensed corn distillers solubles samples. A pre-NDF fat extraction must be completed prior to analyzing high fat feeds for NDF. Corn should be ground through a 1-mm screen on a Tecator Cyclotec sample mill to accurately determine corn NDF content.
Metabolism Characteristics Of Feedlot Diets Containing Different Fat Sources, Virgil R. Bremer, Kelsey Rolfe, Crystal D. Buckner, Galen E. Erickson, Terry J. Klopfenstein
Metabolism Characteristics Of Feedlot Diets Containing Different Fat Sources, Virgil R. Bremer, Kelsey Rolfe, Crystal D. Buckner, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A metabolism trial was conducted to evaluate the effects of dietary fat source on the metabolism characteristics of feedlot steers fed 8.5% fat (7% fatty acids) diets. Steers fed condensed corn distillers solubles (CCDS) had lower average pH and greater DM digestibility than those fed corn oil, tallow, or WDGS. Steers fed CCDS also had greater fat and fatty acid digestibility than corn and corn oil fed steers and greater NDF digestibility than corn oil or tallow fed steers. Although CCDS fat is similar to corn oil, the two feeds are digested differently. The omasal fatty acid profile of steers …

Factors Associated With Feed Intake Of Angus Steers, Marco G. Dib, Jeremy F. Taylor, Robert D. Schnabel, L. Dale Van Vleck
Nebraska Beef Cattle Reports
Estimates of variance components and heritability of average daily feed intake (AFI) and residual feed intake (RFI) were obtained using an animal model. Data were from 475 Angus steers raised and fed at the Circle A Ranch (Iberia, Mo.). Pedigree files were provided by the American Angus Association. Estimates of heritability after adjustment for average daily gain (ADG) were 0.56 and 0.60 for AFI and RFI. Selection for feed intake (FI) should be effective if FI records are available. Feed intake needs to be adjusted for age and weight on test. Carcass measurements (fat thickness and rib eye muscle area) …
Effect Of Calving Season And Wintering System On Cow Performance, William A. Griffin, Don C. Adams, Leslie Aaron Stalker, Richard N. Funston, Jacqueline A. Musgrave, Terry J. Klopfenstein, Galen E. Erickson
Effect Of Calving Season And Wintering System On Cow Performance, William A. Griffin, Don C. Adams, Leslie Aaron Stalker, Richard N. Funston, Jacqueline A. Musgrave, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Four years of data from three different calving seasons and two different cow wintering systems were evaluated utilizing 218 cows/year. Cows calved in spring, summer, or fall and were wintered on native Sandhills range or cornstalks. Calving season affected cow body weight (BW) and body condition score (BCS) throughout the production year; calving in the fall reduced number of calves weaned per cow. No differences were observed between cows wintered on Sandhills range and those wintered on cornstalks.

Acid Marination For Tenderness Enhancement Of The Beef Bottom Round, Jeremy H. Hinkle, Chris R. Calkins, Amilton S. De Mello Jr., Lasika S. Senaratne, Siroj Pokharel
Nebraska Beef Cattle Reports
Two experiments were conducted to evaluate acid marination to enhance tenderness of the beef bottom round (m. biceps femoris). Both experiments consisted of 3 acid types (acetic, lactic, and citric) and two concentrations (0.1 and 0.5 M in Exp. 1; 0.75 and 1.5 M in Exp. 2). There were no effects of acid marination on beef tenderness in Exp. 1, although lightness (L*) increased and redness decreased from 0 to 8 hours post-marination. Acetic and lactic acid (0.75 or 1.5 M) improved shear force values above those achieved by citric acid. Both lightness and redness permanently decreased in Exp. 2. …
Tympanic Temperature Profiles Of Confined Beef Cattle, Terry L. Mader, Leslie J. Johnson
Tympanic Temperature Profiles Of Confined Beef Cattle, Terry L. Mader, Leslie J. Johnson
Nebraska Beef Cattle Reports
Angus crossbred yearling steers were used to evaluate tympanic temperature (TT) profile of cattle displaying high, moderate, or low levels of heat stress. Data indicate cattle that do not adequately cool down at night are prone to greater body temperatures during a subsequent hot day. Cattle that are prone to displaying moderate levels of heat stress but can cool at night will maintain average tympanic temperatures at or near those of cattle that tend to consistently maintain lower peak tympanic temperatures. In addition, during cooler and moderately hot periods, cattle change TT in a stair-step or incremental pattern, while under …
Supplementing Wet Distillers Grains Mixed With Low Quality Forage To Grazing Cow/Calf Pairs, Brandon L. Nuttelman, William A. Griffin, Terry J. Klopfenstein, Walter H. Schacht, Leslie Aaron Stalker, Jacqueline A. Musgrave, Jerry D. Volesky
Supplementing Wet Distillers Grains Mixed With Low Quality Forage To Grazing Cow/Calf Pairs, Brandon L. Nuttelman, William A. Griffin, Terry J. Klopfenstein, Walter H. Schacht, Leslie Aaron Stalker, Jacqueline A. Musgrave, Jerry D. Volesky
Nebraska Beef Cattle Reports
Two studies were conducted over two years during the summer grazing season to determine the effect of grass intake when grazing cow/calf pairs were supplemented wet distillers grains (WDGS) with low quality forage. In 2007, a mixture of 45% WDGS and 55% grass hay was fed. In 2008, three blends of 50:50, 60:40, and 70:30 WDGS and wheat straw were fed. Supplemented cows and calves outgained non-supplemented groups in 2007. There were no differences in animal performance during 2008. Grazed forage intake was reduced by supplementing WDGS mixed with wheat straw without negatively affecting animal performance.
Comparison Of Feeding Wet Distillers Grains In A Bunk Or On The Ground To Cattle Grazing Native Sandhills Winter Range, Jacqueline A. Musgrave, Leslie Aaron Stalker, Matthew C. Stockton, Terry J. Klopfenstein
Comparison Of Feeding Wet Distillers Grains In A Bunk Or On The Ground To Cattle Grazing Native Sandhills Winter Range, Jacqueline A. Musgrave, Leslie Aaron Stalker, Matthew C. Stockton, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Two experiments determined the effects of feeding wet distillers grains with solubles (WDGS), either on the ground or in a bunk, to cattle grazing native Sandhills winter range. In Exp. 1, frequency of supplementation had no effect on cow body weight (BW) or body condition score (BCS). BCS and BW of cows fed in a bunk were improved compared to cows fed on the ground. In Exp. 2, steers fed in a bunk had greater average daily gain than steers fed on the ground. Feeding WDGS on the ground resulted in 13-20% waste and cost between$0.03 and $0.045 per day.
Extending Grazing In Heifer Development Systems Decreases Cost Without Compromising Production, Daniel M. Larson, Andrea S. Cupp, Richard N. Funston
Extending Grazing In Heifer Development Systems Decreases Cost Without Compromising Production, Daniel M. Larson, Andrea S. Cupp, Richard N. Funston
Nebraska Beef Cattle Reports
Three experiments compared heifer development in the dry lot, grazing either dormant winter range or corn crop residue. Grazing corn residue may reduce pre-breeding gain and in doing so increase age at puberty. Compared to dry lot development, grazing corn residue reduced AI pregnancy rate, but final pregnancy rate was similar for both development tsystems. Calf production and rebreeding efficiency were not affected by the development system. However, grazing corn residue during heifer development reduced cost compared to development in the dry lot. Developing heifers by grazing dormant forage does not affect final pregnancy rate and reduces cost, improving the …
Feeding Fiber From Wet Corn Gluten Feed And Corn Silage In Feedlot Diets Containing Wet Distillers Grains Plus Solubles, Amy R. Rich, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Feeding Fiber From Wet Corn Gluten Feed And Corn Silage In Feedlot Diets Containing Wet Distillers Grains Plus Solubles, Amy R. Rich, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Nebraska Beef Cattle Reports
A feedlot experiment evaluated the effect of increasing fiber in distillers grains diets on ADG, F:G, and nutrient mass balance. The treatments consisted of 1) 30% modified distillers grains plus solubles, no roughage (MDGS), and 2) 30% modified distillers grains plus solubles, 30% wet corn gluten feed, and 15% corn silage (MDGS+fiber). The remainder of each diet consisted of a 1:1 ratio of high moisture corn and dry rolled corn and 5% supplement. Feeding MDGS+fiber increased (P < 80.02) ADG, DMI, and HCW; however, it did not improve F:G compared to MDGS. By increasing the fiber content of the diet, more organic matter (OM) and N remained in the manure. Percentage N loss was not different between dietary treatments; however, amount of N lost increased with MDGS + fiber due to the greater N intake and excretion.
Effects Of Using Wet Distillers Grains With Solubles To Adapt Cattle To Finishing Diets On Feed Intake, Ruminal Ph, And Ruminal Hydrogen Sulfide Concentration, Kelsey Rolfe, Galen E. Erickson, Terry J. Klopfenstein, Judson Vasconcelos
Effects Of Using Wet Distillers Grains With Solubles To Adapt Cattle To Finishing Diets On Feed Intake, Ruminal Ph, And Ruminal Hydrogen Sulfide Concentration, Kelsey Rolfe, Galen E. Erickson, Terry J. Klopfenstein, Judson Vasconcelos
Nebraska Beef Cattle Reports
An adaptation strategy with wet distillers grains with solubles (WDGS) fed at decreasing levels (87.5 to 35%) was compared to a traditional grain adaptation with decreasing forage (45 to 7.5%) when adapting steers to a common finishing diet. Traditionally adapted steers had higher intake in steps one through three compared to steers adapted with distillers grains. However, DMI was not different between the two adaptation systems in step four, or when steers were on the finishing diet. Ruminal pH was higher for traditionally adapted steers compared to steers adapted to distillers grains in adaptation diets two and three. Ruminal hydrogen …
Routine Hedging Of Fed Cattle Sales Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Routine Hedging Of Fed Cattle Sales Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Nebraska Beef Cattle Reports
Short futures hedges in the Chicago Mercantile Exchange live cattle futures contract were evaluated to determine if profit variability could be decreased for calf-fed and yearling production systems. Results indicated standard deviations of calf-fed profits could be reduced by $35-$47/head through routine hedging. Routine hedges of yearling cattle, however, resulted in profit declining nearly $50/head, but profit variability also decreased.

Effects Of Feeding Wet Distillers Grains Plus Solubles On Feedlot Manure Value, Virgil R. Bremer, Terry J. Klopfenstein, Galen E. Erickson, Richard K. Koelsch, Raymond E. Massey, Judson Vasconcelos
Nebraska Beef Cattle Reports
Feeding wet distillers grains plus solubles (WDGS) improves the fertilizer value and net value of feedlot manure for all feedlot sizes. The net fertilizer value of feedlot manure increased 375% to 550% since 2006. Valuing manure at 2008 fertilizer nutrient prices and feeding 20% or 40% WDGS instead of feeding a corn-based diet improved profitability by $7 to $17 per steer finished ($4 to $11 per ton of manure).
Comparison Of Dry Distillers Or Modified Wet Distillers Grains Plus Solubles In Wet Or Dry Forage Based Diets, Mallorie Willken, Terry L. Mader, Galen E. Erickson, Leslie J. Johnson
Comparison Of Dry Distillers Or Modified Wet Distillers Grains Plus Solubles In Wet Or Dry Forage Based Diets, Mallorie Willken, Terry L. Mader, Galen E. Erickson, Leslie J. Johnson
Nebraska Beef Cattle Reports
Modified wet distillers grains plus solubles (MDGS) or dry distiller grains plus solubles (DDGS) in combination with wet or dry forages were fed to growing steer calves (n =192). They were fed one of four treatments in a 2 x 2 factorial arrangement with factors as wet or dry forage and MDGS or DDGS for 105 days. Gain and feed-to-gain ratio (F:G) of steers fed MDGS were similar to those fed DDGS. Feeding wet forage significantly improved average daily gain (ADG) and F:G compared to feeding dry forage, which likely reflects forage quality in this study.

Effect Of The Grains-To-Solubles Ratio In Diets Containing Wet Distillers Grains ± Solubles Fed To Finishing Steers, Corineah M. Godsey, Matt K. Luebbe, Joshua R. Benton, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Wet distillers grains plus solubles (WDGS) were fed at 0%, 20% or 40% (DM basis) with varying ratios of distillers grains (WDG) to distillers solubles (DS) to determine effect of inclusion level and amount of solubles on steer performance and carcass characteristics. There was no interaction between WDG inclusion level and WDG:DS ratio. As WDG ± S inclusion increased from 0% to 40% diet DM, final BW and average daily gain (ADG) increased linearly (P = 0.03), while feed-to-gain ratio (F:G) decreased linearly (P < 0.01). However, performance was not affected by the proportion of DS in WDG ± S (P > 0.10).

Nebraska Beef Cattle Reports
Yearling steers (n=268) were fed 0%, 10%, 20%, 30%, 40% or 50 % modified wet distillers grains with solubles (MWDGS; DM basis). Marbling attributes, intramuscular fat content and fatty acid profile of beef were analyzed. Treatments did not alter marbling score, marbling distribution or fat content. Slight differences were identified for marbling texture of Choice carcasses. Values of polyunsaturated, Omega 6 and trans fatty acids linearly increased as levels of modified wet distillers grains increased. Feeding this byproduct increases polyunsaturated, trans and Omega 6 fatty acids in beef.

Nebraska Beef Cattle Reports
Effects of the addition of 0% to 40% wet distillers grains plus solubles (WDGS) or 0% to 20% condensed corn distillers solubles (CCDS) to feedlot diets containing high moisture corn (HMC) and 35% wet corn gluten feed (WCGF) were evaluated. As WDGS replaced HMC, average daily gain (ADG) decreased linearly and dry matter intake (DMI) tended to decrease. Replacement of HMC with WDGS in the 35% WCGF diet caused a linear decrease in ADG and a trend for a linear decrease in DMI. When CCDS replaced HMC, no difference in steer performance was observed. The sulfur content, rather than fat …

Effects Of Environmental Factors On Body Temperature Of Feedlot Cattle, Rodrigo Arias, Terry L. Mader
Nebraska Beef Cattle Reports
Tympanic temperature of 32 Angus steers (919 ± 7.5 lb) was measured with Micro-T ibuttons or the Stowaway data loggers. Environmental variables were collected using weather stations located in the pens to evaluate factors influencing body temperature. A multiple regression analysis was used to evaluate the effects of these factors on body temperature of feedlot cattle. Tympanic temperature tended to be higher for Stowaway compared to Micro-T data loggers (102.6 vs. 102.41°F ± 0.072, respectively; P = 0.053). Tympanic temperature was driven primarily by outgoing solar radiation and wind speed (R2=0.79).

Fatty Acid Composition Of Beef From Cattle Fed Wet Distillers Grains Diets Supplemented With Vitamin E, Lasika S. Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Timothy P. Carr, Galen E. Erickson
Nebraska Beef Cattle Reports
Crossbred yearlings (n = 90) were allotted to one of ten diets containing 0%, 20% and 40% wet distillers grains (WDG) with or without vitamin E supplementation and distillers solubles. Strip loin and tenderloin steaks were obtained and tested for their fatty acid profiles using gas chromatography. WDG diets increased linearly (P < 0.05) the polyunsaturated fatty acids (PUFA) containing 18 or more carbons and trans fatty acids in both muscles. No significant differences were found for total saturated and unsaturated fatty acids. Dietary inclusion of neither vitamin E nor distiller solubles significantly changed PUFA, trans, omega-6 or omega-3 fats in strip loins and tenderloins. Therefore, changes in the fat¬ty acid profile of beef are a consequence of WDG, not the solubles or vitamin E.
A Rapid Method To Evaluate Oxidation Capacity Of Fresh Beef, Lasika S. Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Timothy P. Carr
A Rapid Method To Evaluate Oxidation Capacity Of Fresh Beef, Lasika S. Senaratne, Chris R. Calkins, Amilton S. De Mello Jr., Timothy P. Carr
Nebraska Beef Cattle Reports
A method to determine the capacity of beef to oxidize was developed by spectrophotometrically measuring the formation of conjugated dienes after inducing oxidation. The assay was tested by comparing the oxidation capacity and oxidation products (2-thiobabutaric acid reactive substances) of beef stored in a cooler with various packaging types. There was an inverse relationship between oxidation capacity and oxidation products. As oxidation increases, the oxidation capacity of samples declines. This method of measuring oxidation capacity provides useful information without having to wait for oxidation to occur.
