Nebraska Beef Cattle Reports
A pre-process fractionation produces a feed product called E-corn, which is low in fat and contains heat-treated starch. E-corn replaced dry rolled corn at 0, 20, 40, or 60% (DM basis) in finishing diets containing either 30% wet distillers grains plus solubles (WDGS) or 30% wet corn gluten feed (WCGF). E-corn level x byproduct type interactions were not observed. Dry matter intake increased quadratically to E-corn inclusion level (P = 0.04), while F:G responded cubically with 20% and 60% E-corn inclusion having the lowest F:G (P = 0.02). However, when E-corn level increased from 0 to 60% of diet DM, …

Two hybrids of grain sorghum, the AWheatland x RTx430 hybrid (CON) and its near isogenic brown midrib counterpart (BMR), were used in a 65-day residue grazing experiment. Grain sorghum was planted in 4 replications for each treatment within the same field, and grazed with 6 steers/replication. Samples of the sorghum residue were collected on days 1, 31, and 60 for neutral detergent fiber (NDF) and in vitro NDF digestibility analysis. Steers grazing the BMR treatment gained 1.55 lb/day while the steers grazing the CON treatment gained 1.32 lb/day (P = 0.14). The BMR and CON were similar in NDF (73.5%), …

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.
Vaccination To Reduce The Prevalence Of Escherichia Coli O157:H7 In Feedlot Cattle Fed Wet Distillers Grains Plus Solubles, Amy R. Rich, Ashlynn N. Jepson, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, David R. Smith, Rodney A. Moxley
Vaccination To Reduce The Prevalence Of Escherichia Coli O157:H7 In Feedlot Cattle Fed Wet Distillers Grains Plus Solubles, Amy R. Rich, Ashlynn N. Jepson, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, David R. Smith, Rodney A. Moxley
Nebraska Beef Cattle Reports
A clinical trial in summer of 2008 evaluated effects of feeding 0 (CONTROL) or 40% wet distillers grains plus solubles (WDGS) with and without vaccination against E. coli O157:H7 on the probability of shedding E. coli O157:H7 in the feces. No interaction (P = 0.97) was observed between vaccination and diet for E. coli O157:H7 shedding. Steers fed WDGS were 2.1 times more likely (P < 0.01) to shed E. coli O157:H7 than cattle fed CONTROL. Vaccination resulted in cattle that were 43% less likely (P < 0.01) to test positive for E. coli O157:H7 than the unvaccinated cattle.
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.
Routine Hedging Of Corn Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Routine Hedging Of Corn Price For Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Nebraska Beef Cattle Reports
Several corn hedging scenarios involving a combination of cash and futures market transactions were evaluated for calf-fed and yearling production systems. All yearling corn hedging scenarios assessed were effective in only slightly reducing profit risk, while the calf-fed corn hedging scenario actually increased profit risk. Calf-fed and yearling corn hedging scenarios generally generated positive average returns to hedging by lowering net corn prices. The yearling corn hedging scenarios initiated closer to feedlot placement were associated with greater average profits as compared to those hedges initiated when yearlings were initially purchased.
Determinants Of Profit Variability In Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Determinants Of Profit Variability In Calf-Fed And Yearling Production Systems, Rebecca M. Small, Darrell R. Mark, Terry J. Klopfenstein Klopfenstein
Nebraska Beef Cattle Reports
Factors that were determinants of profit variability in calf-fed and yearling beef production systems were identified and ranked. The analysis indicated cattle prices have the greatest influence on profit variation for both systems and on all backgrounding and finishing phases of the yearling system. Prices of feedstuffs (i.e., corn prices, wet corn gluten feed prices, and pasture and cornstalk rental rates) were the next most important factors explaining profit risk. Cattle performance variables and interest rates had the smallest impact on profit variation.
Evaluation Of Storage Covers When Wet Distillers Byproducts Are Mixed And Stored With Forages, Dana L. Christensen, Kelsey Rolfe, Terry J. Klopfenstein, Galen E. Erickson
Evaluation Of Storage Covers When Wet Distillers Byproducts Are Mixed And Stored With Forages, Dana L. Christensen, Kelsey Rolfe, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Wet corn co-products were mixed with forage and stored in 55 gallon barrelswith different covers mimicking bunker storage methods to determine shrink losses and spoilage. Three mix combinations and seven cover treatments were used to compare spoilage levels of covered co-product mixes vs. uncovered mixes. Spoilage and losses of the mix were effectively reduced with all covers, with losses reduced from 8 to 9% when uncovered, to 1 to 5% when different cover treatments were used.

This research was conducted to identify alternative cuts that would be acceptable in popular dishes in Japan and Korea in order to encourage usage of a broader portion of beef carcasses that qualify for export. Typical dishes were tested twice (6 panels per country) using traditional and three alternative beef muscles. Dishes were compared regarding appearance, aroma, juiciness, tenderness, flavor, and overall acceptability by natives of each country who served as panelists. Japanese dishes were sukiyaki (sauté), shabu-shabu (hot pot), and yakiniku (grill); Korean dishes were jang jo rim (boiled), miyeok-guk (soup), and kalbi (grill). Alternative muscles were selected because …
Fiber Digestibility And Rumen Ph For Diets Containing Wet Corn Gluten Feed Or Wet Distillers Grains With Solubles, Crystal D. Buckner, Kelsey Rolfe, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Fiber Digestibility And Rumen Ph For Diets Containing Wet Corn Gluten Feed Or Wet Distillers Grains With Solubles, Crystal D. Buckner, Kelsey Rolfe, Nathan Meyer, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Seven ruminally cannulated steers were used to evaluate fiber digestibility and rumen pH for diets containing 35 or 88% wet corn gluten feed (WCGF) or 35% wet distillers grains with solubles (WDGS). These diets were top-dressed with or without a direct-fed microbial (DFM). Interactions were observed for DM and NDF digestibility. Feeding 88% WCGF decreased DM digestibility, but NDF digestibility increased especially with the DFM. Rumen pH was greatest for steers fed 88% WCGF and lowest for steers fed 35% WCGF.

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 …
Tympanic Temperature Of Steers Fed Different Levels Of Metabolic Energy Intake During Summer And Winter, Rodrigo A. Arias, Terry L. Mader
Tympanic Temperature Of Steers Fed Different Levels Of Metabolic Energy Intake During Summer And Winter, Rodrigo A. Arias, Terry L. Mader
Nebraska Beef Cattle Reports
Tympanic temperatures (TT) of steers were recorded during July (8 days) and January (6 days). In each experiment, steers were fed 11, 18, or 25 Mcal/day ME in a roughage-based diet, or 18, 25, or 32 Mcal/day ME in a concentrate-based diet. Tympanic temperatures were greater during summer than during winter. Also, steers fed a concentrate diet had greater TT than those fed a roughage diet. Linear equations were obtained to estimate TT of cattle for summer and winter seasons. During the winter, TT response to MEI was dependent on the type of diet. Resultsdemonstrate that increases in the energy …

Nebraska Beef Cattle Reports
Anti-Müllerian Hormone (AMH) has been associated with follicle number and age of the ovary. Therefore, our hypothesiswas that AMH was a biomarker for both follicle number and ovarian function in the beef cow. Ovaries were collected by flank laparotomy. The number of follicles increased as cows aged from 1.5 to 6 years and began to decrease thereafter; however, the size of the ovary continued to increase with advanced age. Expression of the AMH gene increased with increasing follicle number in 2-year-old beef cows. These results suggest that heifers with larger ovaries will have greater numbers of follicles and greater productivity, …

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) …
Relationship Of Metabolizable Protein Balance, Purine Derivative Excretion, And 3-Methyl Histidine Excretion To Feed Efficiency In Individually Fed Finishing Heifers, William A. Griffin, Kelsey Rolfe, Grant I. Crawford, Terry J. Klopfenstein, Galen E. Erickson, Phillip S. Miller, Ruth M. Diedrichsen
Relationship Of Metabolizable Protein Balance, Purine Derivative Excretion, And 3-Methyl Histidine Excretion To Feed Efficiency In Individually Fed Finishing Heifers, William A. Griffin, Kelsey Rolfe, Grant I. Crawford, Terry J. Klopfenstein, Galen E. Erickson, Phillip S. Miller, Ruth M. Diedrichsen
Nebraska Beef Cattle Reports
Individually fed heifers were used to determine the relationship of 3-methyl histidine, purine derivatives, and metabolizableprotein balance to feed efficiency. Heifers were fed finishing dietsthat were either deficient or sufficient in metabolizable protein. Urine samples were collected and analyzed for early, late, and entire feeding period concentrations of 3-methyl histidine, purine derivatives, and creatinine. Results from this study indicated a negative relationship between feed efficiency and metabolizable protein balance, and no relationship between 3-methyl histidine excretion and feed efficiency, suggesting that protein turnover and microbial protein synthesis are not related to feed efficiency
Estrous Synchronization Increases Early Calving Frequency, Which Enhances Steer Progeny Value, Daniel M. Larson, Jacqueline A. Musgrave, Richard N. Funston
Estrous Synchronization Increases Early Calving Frequency, Which Enhances Steer Progeny Value, Daniel M. Larson, Jacqueline A. Musgrave, Richard N. Funston
Nebraska Beef Cattle Reports
Calving records collected between 2000 and 2008 at the Gudmundsen Sandhills Laboratory, Whitman, Neb., were used to determine the effect of estrous synchronization on calving distribution and the impact of time of calving on carcass characteristics. More synchronized cows calved during the first 21 days compared to non-synchronized cows, and calves born to synchronized dams were heavier at weaning. Calves born in the first 21 days of the calving season had greater carcass weights, marblingscores, and yield grades than later born calves. In addition, the percentage of steers grading premium choice or greater and the total carcass value declined as …

Nebraska Beef Cattle Reports
Replacement heifers were developed on cornstalks (Exp. 1, 2, and 3), dry lot (Exp. 1 and 2), or winter range (Exp. 3). In Exp. 1, pregnant heifers were individually fed during mid to late gestation. Heifers developed on cornstalks were more feed efficient than heifers developed in a dry lot. In Exp. 2 and 3, pregnant heifers grazed cornstalks during mid to late gestation. Heifers developed on cornstalks gained more and were more efficient, especially compared to heifers developed in a dry lot. These data provide evidence of an adaptive response to grazing low quality forages and may be beneficial …
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 …

Comparing The Energy Value Of Wet Distillers Grains To Dry Rolled Corn In High Forage Diets, Brandon L. Nuttelman, Matt K. Luebbe, Terry J. Klopfenstein, Joshua R. Benton, Galen E. Erickson
Nebraska Beef Cattle Reports
Sixty crossbred steers were used to compare the energy value of wet distillers grains (WDGS) to dry rolled corn (DRC) in high forage diets at three levels. DRC was included at 22.0, 41.0, and 60.0% of the diet (DM), and WDGS was included at 15.0, 25.0, and 35.0% of the diet (DM). Diets were formulated to meet degradable intake protein and metabolizable protein requirements. Cattle consuming WDGS gained more than DRC cattle. Average daily gain increased with increasing levels of DRC and WDGS. The energy value of WDGS was calculated using the National Research Council model (1996). In this study, …

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.

Genetic And Phenotypic Parameter Estimates For Feed Intake And Other Traits In Growing Beef Cattle, Kelsey Rolfe, Merlyn K. Nielsen, Calvin L. Ferrell, Thomas G. Jenkins
Nebraska Beef Cattle Reports
The goal of this study was to estimate genetic and phenotypic parameters for growth, feed intake, feed efficiency, and temperament traits in a mixed-breed composite population of growing beef cattle. Intake and gain:feed (G:F) were moderately heritable; however, residual feed intake (RFI) was more heritable than other measures of feed efficiency. Adjusting RFI and G:F for carcass fatness had little effect on heritability and correlations with remaining traits. Flight speed was moderately heritable and highly repeatable. Flight speed was not highly correlated with measures of intake or feed efficiency. Some small breed effects were observed. High heritability estimates indicate that …
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 …

Plant And Animal Responses To Grazing Systems In The Nebraska Sandhills, Walter H. Schacht, Jerry D. Volesky, Mitchell B. Stephenson, Terry J. Klopfenstein, Don C. Adams
Nebraska Beef Cattle Reports
Short duration grazing (SDG) and deferred rotation (DR) were compared in a 10-year study conducted on uplandnativepastures in the northern NebraskaSandhills. Herbage production of cool-season grasses and sedges was less on the SDG pastures, although total herbage production (including warm and cool season herbage) did not differ consistently between the two grazing systems. The decline in diet quality (CP and IVOMD) through the 5-month grazing season did not differ consistently between the two systems, and ADG of spayed heifers was similar. The lack of increased forage production and animal performance responses to SDG indicate that the higher input costs associated …

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 …

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.
