Determination Of Diet Protein And Digestibility Of Native Sandhills Upland Range, Bobbi Gene Geisert, Terry J. Klopfenstein, Don C. Adams, Jacqueline A. Musgrave, Walter H. Schacht
Nebraska Beef Cattle Reports
A significant year by grazing level effect was detected on CP content of diet samples collected from 2003 to 2005 at the Gudmundsen Sandhills Laboratory. During drought years (2003 and 2004) cows selected plants which were higher in CP and lower in digestibility. High levels of grazing pressure decreased diet IVOMD compared to diets from ungrazed and moderately grazed pastures. Prediction models generated from these data predict dietary CP and organic matter disappearance (OMD) of cattle grazing native Sandhills range pastures.

Nebraska Beef Cattle Reports
Seven ruminally cannulated steers were used in a metabolism experiment to determine the effects of distillers grains level (0% or 40% of diet DM) on diet digestibility and rumen metabolism in diets consisting of dry-rolled, high-moisture, or steam-flaked corn. Intakes were greater while digestibility was reduced for DM and organic matter in steers fed 40% compared to 0% distillers grains. Average and maximum pH were less for steers fed 40% distillers grains, but pH change and variance were also less for 40% compared to 0% WDGS. Feeding WDGS does not increase rumen pH, but does decrease variance. Starch intakes were …
Aerobic Composting Or Anaerobic Stockpiling Of Feedlot Manure, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist
Aerobic Composting Or Anaerobic Stockpiling Of Feedlot Manure, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Matthew A. Greenquist
Nebraska Beef Cattle Reports
Two manure management and storage methods, manure stockpiled anaerobically or composted aerobically for 104 days were evaluated. Nitrogen recovery was 85.7% and 56.4% for stockpiled and composted manure, respectively. Organic nitrogen concentrations were greater for composted manure while ammonium nitrogen concentrations were greater for stockpiled manure. Simulation of hot, dry conditions during field application indicated the amount of ammonia nitrogen lost from stock¬piled manure was not great enough to offset the total nitrogen recovery advantage of this method. When evaluated on a nutrient basis, stockpiled manure has greater value as a fertilizer compared with composted manure in this study.

Total And Water Soluble Phosphorus Content Of Feedlot Cattle Feces And Manure, Virgil R. Bremer, Crystal D. Buckner, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
The percentage of feedlot feces and manure P that is water soluble was 41% (not accounting for additional soluble P from urine) and 24% respectively. The interaction of feces and urine with minerals and metals reduced the water solubility of P in feedlot manure relative to feces. Increasing dietary P level increased manure P concentration and water solubility of manure. Manure P from cattle fed feedlot diets containing 0.30% to 0.50% P was 28% water soluble P. The water solubility of P in feedlot feces and manure is an indicator of the potential for P runoff from feedlots and fields …
Effect Of Backgrounding Gain, Grazing Length And Dry Distillers Grain Consumption On Performance And Carcass Traits Of June Born Cattle, J. Alan Taylor, Leslie Aaron Stalker, Terry J. Klopfenstein, Don C. Adams, William A. Griffin
Effect Of Backgrounding Gain, Grazing Length And Dry Distillers Grain Consumption On Performance And Carcass Traits Of June Born Cattle, J. Alan Taylor, Leslie Aaron Stalker, Terry J. Klopfenstein, Don C. Adams, William A. Griffin
Nebraska Beef Cattle Reports
June-born cattle backgrounded at a lower rate during the winter were unable to fully compensate during sum¬mer grazing for restricted gain during backgrounding. Increased gain during backgrounding resulted in cattle being heavier for all market periods. The higher cost associated with increased gain was offset by heavier sale weights. Cattle grazing meadow regrowth had improved feedlot performance and heavier finished weight. Backgrounding cattle grazing winter range supplemented with DDG costs less than backgrounding cattle in a drylot. Supplementing with DDG during summer grazing decreased forage intake and increased gain, with 1.8 lb/head/day being more cost effective than 5 lb/head/day.
Effect Of Pre-Breeding Weight And Mga Supplementation On Heifer Performance, Jeremy L. Martin, Kelly W. Creighton, Jacqueline A. Musgrave, Terry J. Klopfenstein, Richard T. Clark, Don C. Adams, Richard N. Funston
Effect Of Pre-Breeding Weight And Mga Supplementation On Heifer Performance, Jeremy L. Martin, Kelly W. Creighton, Jacqueline A. Musgrave, Terry J. Klopfenstein, Richard T. Clark, Don C. Adams, Richard N. Funston
Nebraska Beef Cattle Reports
Developing heifers to reach a target weight of 50% of mature body weight at the beginning of the breeding season is an effective method for reducing heifer development cost. Net costs to produce a bred yearling heifer and 2-year-old cow were lower when heifers were developed to 50% rather than 55% of mature body weight, regardless of breeding season length. Administration of oral progestin to heifers developed to 50% mature body weight prior to breeding did not affect reproductive performance during the first breeding season when heifers were exposed to bulls 13 days after the end of progestin treatment.

Comparison Of Crude Protein And Digestibility Of Diets Of Grazing Cattle At Different Sandhills Range Sites, Bobbi Gene Geisert, Terry J. Klopfenstein, Don C. Adams, Jacqueline A. Musgrave, John Maddux
Nebraska Beef Cattle Reports
Diet samples were collected May through September (2003) and May through November (2004) using esophageally fistulated cows at ranches in the Sandhills and southwest Nebraska. Differences in CP between the two locations were significant. Diets collected in May and June had higher CP (P = 0.04) than those collected in August through November. No interactions were detected between year and location in diet digestibility and diet digestibility was similar for southwest Nebraska and Sandhills diets.
Evaluation Of Storage Methods For Wet Distillers Grains Plus Solubles With Added Forages, Daniel R. Adams, Mallorie F. Wilken, Brandon L. Nuttleman, Luke M. Kavorik, Joshua R. Benton, Matthew A. Greenquist, Galen E, Erickson, Terry J. Klopfenstein, Richard J. Rasby

Nebraska Beef Cattle Reports
Six experiments indicated minimum amounts of dry feedstuffs needed for storage of wet distillers grains plus solubles (WDGS) in a silo bag, with a constant pressure of 300 psi, were 15% grass hay, 12.5% wheat straw, 22.5% alfalfa hay, 50% dry distillers grains and 60% wet corn gluten feed (WCGF) with the remaining percentage as WDGS (DM basis). For storage in bunker silos, the recommended levels are 40% grass hay, 30% wheat straw and 30% cornstalks.
Dried Distillers Grains Supplementation To Yearling Cattle Grazing Smooth Bromegrass: Response And Performance Profile Summary, Matthew A. Greenquist, Terry J. Klopfenstein, Galen E. Erickson, Matt K. Luebbe
Dried Distillers Grains Supplementation To Yearling Cattle Grazing Smooth Bromegrass: Response And Performance Profile Summary, Matthew A. Greenquist, Terry J. Klopfenstein, Galen E. Erickson, Matt K. Luebbe
Nebraska Beef Cattle Reports
Four years of data were summarized to evaluate yearling performance on smooth bromegrass when supplemented with dried distillers grains (DDG). On average cattle were supplemented 0.525% of BW daily with DDG for the entire grazing period (84 to 156 days). Daily gains were increased 0.55 lb/day for the entire grazing season. Performance from the last two years of data show a quadratic decrease in ADG as grazing days increase and forage quality decreases for both the supplemented and nonsupplemented cattle. The response to DDG supplementation increases with increasing grazing days.

The Effects Of Supplementing Wet Distillers Grains Mixed With Wheat Straw To Growing Steers, Brandon L. Nuttelman, Terry J. Klopfenstein, William A. Griffin, Matt K. Luebbe
Nebraska Beef Cattle Reports
A growing study compared feeding wet distillers grains, dried distillers grains, and a mix of 66% wet distillers grains and 33% wheat straw as supplements to a forage-based diet. Steers were supplemented 0, 2, 4, or 6 lb distillers grains/head daily. Wet distillers grains and dried distillers grains produced higher final body weight and dry matter intake compared to the mix. Increasing levels of distillers grains increased performance in forage based diets and wet grains mixed with straw reduced forage intake.
Meta-Analysis Of Unl Feedlot Trials Replacing Corn With Wcgf, Virgil R. Bremer, Galen E. Erickson, Terry J. Klopfenstein
Meta-Analysis Of Unl Feedlot Trials Replacing Corn With Wcgf, Virgil R. Bremer, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A meta-analysis of UNL feedlot trials was conducted to evaluate the effect of replacing dry-rolled or high-moisture corn with wet corn gluten feed (WCGF) on feedlot cattle performance and carcass characteristics. The feeding value of WCGF was dependent on ratio of steep to corn bran of the WCGF. The performance of cattle fed WCGF composed of wet bran and steep was similar to corn fed cattle. Feeding and carcass performance of cattle fed WCGF composed of dry bran, steep, and germ improved linearly as dietary inclusion increased.
Effect Of Inclusion Level Of Modified Distillers Grains Plus Solubles In Finishing Steers, Taia J. Huls, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein
Effect Of Inclusion Level Of Modified Distillers Grains Plus Solubles In Finishing Steers, Taia J. Huls, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Modified distillers grains plus solubles (MDGS) was fed at 0%, 10%, 20%, 30%, 40%, and 50% of the diet (DM basis) replacing dry rolled corn and high moisture corn. The feeding value of MDGS is 123% to 109% the value of corn as MDGS inclusion increases from 10% to 50% (DM basis). Except for hot carcass weight and calculated yield grade no differences in carcass characteristics were observed between treatments. Finishing diets including MDGS may be fed up to 50% of diet DM; however, optimal performance is likely between 20% to 40% of the diet DM.
Effect Of Distillers Grains Fat Level On Digestibility, Mark E. Corrigan, Galen E. Erickson, Terry J. Klopfenstein, Nathan F. Meyer
Effect Of Distillers Grains Fat Level On Digestibility, Mark E. Corrigan, Galen E. Erickson, Terry J. Klopfenstein, Nathan F. Meyer
Nebraska Beef Cattle Reports
Four steers were used in a three-period switchback design to determine effects of dry distillers grains fat level on digestibility. Forage based diets were supplemented with distillers grains with differing fat levels (6.9% or 13.3 % dry matter). Intake and digestibility of DM and organic matter did not differ between treatments. Neutral detergent fiber intake was less and digestibility tended to be less in steers supplemented with high fat distillers grains. Differences in fiber type and intake as well as fat intake may be responsible for the small difference in neutral detergent fiber digestibility.

Cattle Code: An Economic Model For Determining Byproduct Returns For Feedlot Cattle, Crystal D. Buckner, Virgil R. Bremer, Terry J. Klopfenstein, Galen E. Erickson, Darrell R. Mark
Nebraska Beef Cattle Reports
Cattle CODE — Coproduct Optimizer Decision Evaluator — is a model developed to predict performance and economic returns when byproducts are fed to finishing cattle. Four scenarios were evaluated to illustrate how the model works and to show sensitivity to corn price and distance from the ethanol plant, which resulted in positive returns for feeding WDGS, Sweet Bran, or DDGS up to 50% of diet DM and under 100 miles distance from the ethanol plant to the feedlot.
Influence Of Corn Hybrid And Processing Method On Finishing Performance And Carcass Characteristics, Flint W. Harrelson, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian
Influence Of Corn Hybrid And Processing Method On Finishing Performance And Carcass Characteristics, Flint W. Harrelson, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian
Nebraska Beef Cattle Reports
Five commercially available corn hybrids were evaluated for finishing cattle performance and carcass characteristics when fed as high-moisture (HMC) or dry-rolled corn (DRC). No significant interactions were observed between hybrid and processing method. Corn hybrid had no significant impact on ADG or DMI, but did have a minor influence on F:G. However, these data suggested that processing as HMC-method had a greater effect on cattle performance than hybrid.

Influence Of Corn Hybrid And Processing Method On Ruminal And Intestinal Digestion, Flint W. Harrelson, Nathan F. Meyer, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian
Nebraska Beef Cattle Reports
Using the mobile bag technique, five commercially available corn hybrids harvested as either dry-rolled or high-moisture corn were evaluated for site and extent of DM and starch digestion. Total-tract DM digestibility was improved 7 to 16 percentage units, and total-tract starch digestibility was improved 9 to 18 percentage units among hybrids when processed as high-moisture corn compared to dry-rolled corn. The results of this trial suggest that hybrid and processing method interact and can influence DM and starch digestibility.

Effects Of Distillers Grains And Manure Management On Nutrient Management Plans And Economics, Virgil R. Bremer, Richard K. Koelsch, Raymond E. Massey, Galen E. Erickson
Nebraska Beef Cattle Reports
Feed Nutrient Management Plan Economics software (FNMP$; Koelsch et al., 2007; available at http://cnmp.unl.edu under software resources) was used to evaluate the effect of distillers grains inclusion and manure application rate on feedlot nutrient management plans. Inclusion of distillers grains in diets resulted in greater nutrient excretion, land requirements, and manure hauling distances. However, the increased cost of manure management from feeding byproducts has the potential to be offset by increased manure fertilizer value. Changing from N-based to a P-based application rate increased the amount of land required and costs to apply manure. However, when manure was applied at a …

Climate Conditions In Bedded Confinement Buildings, Terry L. Mader, Leslie J. Johnson, Sheryl L. Colgan
Nebraska Beef Cattle Reports
Climate conditions in bedded feedlot facilities during summer, fall, and winter seasons were measured. Summer season temperatures and THI levels were greatest at the front of the building. In winter, the building (with a curtain) maintained greater temperature, when compared to outside conditions, by decreasing wind speed through the building. Wind speeds through the building were reduced regardless of curtain usage.
Modeling Daily Water Intake In Cattle Finished In Feedlots, Rodrigo A. Arias, Terry L. Mader
Modeling Daily Water Intake In Cattle Finished In Feedlots, Rodrigo A. Arias, Terry L. Mader
Nebraska Beef Cattle Reports
Simple regression and multiple regression analyses were conducted to estimate factors affecting daily water intake(DWI) of finishing cattle. Seasonal simple linear regression equations were very poor predicting DWI (r2 < 0.15). Best results were obtained with the overall simple regression. The multiple regression analysis showed that daily minimum temperature (or THI), solar radiation, and dry matter intake were the most important factors affecting DWI in cattle finished in feedyards. The following prediction equation was developed: daily water intake, gal*d-1 = -0.52677+ (0.1229 *DMI, lb*d-1) + (0.01137*solar radiation, kcal*d-1) + (0.06529*daily minimum temperature, °F).

Sorting Steers By Weight Into Calf-Fed, Summer Yearlings And Fall Yearling Feeding Systems, Daniel R. Adams, Matt K. Luebbe, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Sorting steers into one of three different feeding periods — calf-feds, summer yearlings, and fall yearlings — resulted in no differences in performance or average carcass characteristics. Sorting decreased the amount of variation in hot carcass weight and carcasses over 950 lbs.
Performance And Economics Of Two Calf Wintering Systems, William A. Griffin, Terry J. Klopfenstein, Galen E. Erickson
Performance And Economics Of Two Calf Wintering Systems, William A. Griffin, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Two wintering systems, cornstalk grazing plus 5 lb/head/day of wet corn gluten feed and cornstalk grazing followed by dry lot where steers were fed hay and supplemented 5 lb/head/day of wet corn gluten feed were evaluated. There were no differences in daily gain, or final body weight for either system. While there were no statistical differences in cost of gain, break-even, or profitability, economics numerically favored steers grazing cornstalks alone.
Evaluation Of Calf-Fed And Long Yearling Production With Increasing Corn Price, William A. Griffin, Terry J. Klopfenstein, Galen E. Erickson, Darrell R. Mark
Evaluation Of Calf-Fed And Long Yearling Production With Increasing Corn Price, William A. Griffin, Terry J. Klopfenstein, Galen E. Erickson, Darrell R. Mark
Nebraska Beef Cattle Reports
An economic comparison of calf-fed and long-yearling production was conducted to determine the impact of increasing corn price on steer profitability. Corn prices of $2.50, $3.50, and $4.50/bu were used. With increasing corn price, feeder prices were assumed to decrease which decreased initial cost more for yearlings than calf-feds. Profitability of yearlings versus calf-feds increased $4-6 for each $1/bu increase in corn price.
Price Discovery In North And West Central Nebraska Livestock Auction Markets, Matthew C. Stockton, Roger K. Wilson, Leslie Aaron Stalker
Price Discovery In North And West Central Nebraska Livestock Auction Markets, Matthew C. Stockton, Roger K. Wilson, Leslie Aaron Stalker
Nebraska Beef Cattle Reports
Price data from west central Nebraska livestock auction markets were used to determine the price discovery and information flow patterns between weight-gender cattle classes using time series analysis and directed acyclical graphs (DAG). Results indicated steers weighing 400-600 lb were the point of price discovery; the price change of each weight of steers impacted the price of the next heavier class of steers. Price movements for 600-700 lb heifers impacted prices of many other weight/gender classes including the price of heavier heifers and steers.
The Cattle Price Cycle: Revisited Again, Matthew C. Stockton, Roger K. Wilson, Leslie Aaron Stalker
The Cattle Price Cycle: Revisited Again, Matthew C. Stockton, Roger K. Wilson, Leslie Aaron Stalker
Nebraska Beef Cattle Reports
New analyses and statistical techniques were applied to historical data to determine if time, changes in production technology, and business structure changes in the sector had altered the length of the cattle price cycle. Most recent work has been done the cattle inventory cycle. The price cycle was shown to be remarkably constant, despite many changes in the industry. Feeder cattle prices have continued to follow an approximate 10-year cycle. The model demonstrates the consistency of the cycle but shows that unexplained price variations occur suggesting caution be employed when it is used as a marketing guide.
Factors That Influence Consumers’ Overall Sensory Acceptance Of Strip Steaks, Jennie M. Hodgen, Bethany M. Johnston, Blaine E. Jenschke, Kent M. Eskridge, Chris R. Calkins
Factors That Influence Consumers’ Overall Sensory Acceptance Of Strip Steaks, Jennie M. Hodgen, Bethany M. Johnston, Blaine E. Jenschke, Kent M. Eskridge, Chris R. Calkins
Nebraska Beef Cattle Reports
Multivariate analysis was used to determine demographic, knowledge, habits, and sensory preferences that influence a consumer’s opinion about the acceptability of strip steaks from corn-fed, barley-fed, and grass-fed beef. Even with all the additional information, most consumers’ final opinions about specific types of steaks are based on how they perceive the flavor, tenderness, and juiciness of the beef.

Tenderness, Sensory, And Color Attributes Of Two Muscles From The Beef Knuckle, Blaine E. Jenschke, Brittni J. Swedberg, Chris R. Calkins
Nebraska Beef Cattle Reports
Twelve USDA Choice and twelve USDA Select quadriceps muscles were fabricated traditionally or the seams it shares with the top and bottom round were separated pre-rigor to test the effect of pre-fabrication on tenderness, sensory, and color. Results from this study indicated treatment had minimal effects on quality attributes. The proximal portions of the knuckle were more tender, lighter in color, and more red when compared to the distal portions, although all were reasonably tender. Pre-fabrication can be conducted without detriment to product quality.

Characteristics Of Beef Finished On Wet Distillers Grains With Varying Types And Levels Of Roughage, Blaine E. Jenschke, Joshua R. Benton, Chris R. Calkins, Timothy P. Carr, Kent M. Eskridge, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Beef knuckles (n = 160) were obtained from source-verified cattle finished on 30% wet distillers grains plus solubles enriched with varying levels of alfalfa hay, corn silage, or corn stalks based on NDF. Our objectives were to determine if roughage inclusion, in conjunction with wet distillers grains plus solubles and cattle location affects beef flavor. Data from this study indicate type and level of roughage inclusion and cattle location have minimal effects on fatty acid profiles and sensory properties of the M. Rectus femoris. However, individual fatty acids of subcutaneous and intramuscular fat were significantly correlated with liver-like off flavor.
Effects Of Wet Distillers Grains Finishing Diets On Fat Content And Marbling Score In Steers, Amilton S. De Mello Jr., Chris R. Calkins
Effects Of Wet Distillers Grains Finishing Diets On Fat Content And Marbling Score In Steers, Amilton S. De Mello Jr., Chris R. Calkins
Nebraska Beef Cattle Reports
Ninety-four, calf-fed, crossbred steers were randomly allocated to three finishing diets consisting of different amounts of wet distillers grains plus solubles (0%, 15% or 30%, DM basis). Steers were fed for 133 days to test the relationship between marbling score and fat content, as well as effects on marbling texture and marbling distribution. Results of this research suggest that feeding up to 30% of wet distillers grains plus solubles has no detrimental effects on marbling in beef.

Sampling Wet Distillers Grains Plus Solubles To Determine Nutrient Variability, Crystal D. Buckner, Sarah J. Vanness, Galen E. Erickson, Terry J. Klopfenstein, Joshua R. Benton
Nebraska Beef Cattle Reports
Dry matter, protein, fat, phosphorus, and sulfur were measured on 100 wet distillers grains plus solubles (WDGS) samples per ethanol plant (6 plants total) with 10 samples/day, 5 consecutive days, and 2 separate months (periods). Coefficients of variation were 1.5% to 4.5% for DM within plant. Fat in WDGS averaged 11.8% and ranged from 10.7% to 13.1% across plants, with ranges of 2 to 5 percentage units within plant. Coefficients of variation were 5% to 8% and as great as 36% within plant for sulfur. The variation in protein and phosphorus were minimal.
Ruminal Methane Production Following The Replacement Of Dietary Corn With Dried Distillers Grains, Eric J. Behlke, Tim G. Sanderson, Terry J. Klopfenstein, Jess L. Miner
Ruminal Methane Production Following The Replacement Of Dietary Corn With Dried Distillers Grains, Eric J. Behlke, Tim G. Sanderson, Terry J. Klopfenstein, Jess L. Miner
Nebraska Beef Cattle Reports
Methane production was measured following the replacement of corn with DDGS in vitro and also after the simultaneous replacement of corn and corn oil with DDGS (for 30% of the diet) in vivo. In vitro substitution of corn with DDGS increased the amount of methane produced per milligram of DM digested. Likewise, in vivo methane production was increased by 44% when corn and corn oil were replaced with DDGS. The greater energy value of DDGS relative to corn in a concentrate-based diet is not due to decreased methanogenesis.
