The Effects Of Corn Price, Shrink, And Harvest Moisture On Corn Silage Economics, Dirk B. Burken, Terry J. Klopfenstein, Galen E. Erickson Erickson
The Effects Of Corn Price, Shrink, And Harvest Moisture On Corn Silage Economics, Dirk B. Burken, Terry J. Klopfenstein, Galen E. Erickson Erickson
Nebraska Beef Cattle Reports
Economic assumptions were applied to corn production to set corn silage prices for breakeven corn production, whether harvested for corn grain or corn silage. Price levels were used for the calculation of returns per finished steer as corn silage inclusion increased in finishing diets containing distillers grains. As corn price increased, the economics of feeding elevated concentrations of corn silage became more favorable. The economic importance of shrink and harvest moisture content were assessed. As corn price increases and the inclusion of corn silage increases, corn silage management decisions have greater economic importance.
Digestibility Of De-Oiled Modified Distillers Grains Plus Solubles In Forage-Based Diets, Meredith L. Bremer, Sarah J. Peterson, Adam L. Shreck Shreck, Galen E. Erickson, Terry J. Klopfenstein, James C. Macdonald
Digestibility Of De-Oiled Modified Distillers Grains Plus Solubles In Forage-Based Diets, Meredith L. Bremer, Sarah J. Peterson, Adam L. Shreck Shreck, Galen E. Erickson, Terry J. Klopfenstein, James C. Macdonald
Nebraska Beef Cattle Reports
Over half of Nebraska’s ethanol plants are removing oil from distillers grains via centrifugation of the thin stillage constituent. Removing oil by this method does not impact intake or total tract digestibility in beef cattle growing diets. However, increasing the concentration of de-oiled distillers grains in the diet significantly improved intake and digestibility. Thus, concentration of distillers grain in the diet has a greater impact on total tract digestibility than the fat content in forage-based diets.

Effect Of Corn Plant Maturity On Yield And Nutrient Quality Of Corn Plants, Cassandra A. Row, Adam L. Shreck, Robert G. Bondurant Bondurant, Curtis J. Bittner, Jana L. Harding, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
Two corn plots (short season, 102-day, and normal season, 111-day corn) were serially harvested to evaluate nutrient, digestibility, and yield change over the duration from half-milk line through black layer. Digestibility of the corn plant decreased as corn plant maturity and NDF content increased. The lower leaf in the normal season plot decreased in digestibility, but did not change in the short season plot. Little change was observed in the digestibility of the internodes across time. The NDF content of the upper plant increased in both plots. The internodes increased in NDF content across time in both plots. The results …

Effect Of 300 Or 400 Mg Daily Of Ractopamine Hydrochloride On Growth Performance And Carcass Characteristics Of Finishing Steers During The Last 14, 28, Or 42 Days, Curtis J. Bittner, Dirk B. Burken, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson, Nathan A. Pyatt
Nebraska Beef Cattle Reports
The effects of ractopamine hydrochloride (Optaflexx®) dosage (0, 300, and 400 mg/head/day) and duration (14, 28, or 42 days) on growth performance were evaluated in feedlot finishing diets. Feeding 300 mg of Optaflexx for 28 or 42 days increased live final BW by 13 and 29 lb, while feeding Optaflexx at 400 mg resulted in 27 or 24 lb increases relative to 0 mg steers, respectively. Feeding 300 mg of Optaflexx for 28 or 42 days would suggest 11.1 or 16.6 lb improvements in HCW, while feeding 400 mg of Optaflexx would suggest 19.7 or 20.7 lb heavier carcasses compared …

Mineral Composition Of Beef Cattle Carcasses, Andrea K. Watson, Jana L. Harding, Matt P. Mccurdy Curdy, Matt J. Hersom, Kristin E. Hales, Clint R. Krehbiel, Galen E. Erickson
Nebraska Beef Cattle Reports
Mineral retention was measured in 76 beef steers. Cattle were grown at different rates of gain and then finished on a common diet. Calcium and P retention were not affected by treatment and were similar between the growing and finishing periods averaging 4.2 g P and 10.8 g Ca /100 g protein gain across both experiments. As ADG during the growing period was decreased, K, Mg, and S mineral retention during the finishing period were increased. Expressing mineral retention as g/100 g protein gain reducedvariation due to animal size and ADG and suggests that current NRC predictions are accurate.
Stocking Rate Effects On Forage Nutrient Composition In Early Summer Pastures, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, K. H. Jenkins, Terry J. Klopfenstein
Stocking Rate Effects On Forage Nutrient Composition In Early Summer Pastures, Jared V. Judy, Jacki A. Musgrave, L. Aaron Stalker Stalker, K. H. Jenkins, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Nebraska Sandhills upland range pastures were used to measure the effectsof stocking rate on forage nutrient content in early summer pastures. Stocked pastures had lower CP, in vitroorganic matter digestibility, forage availability, and higher NDF compared with ungrazed pastures. Clipped samples of current year growth had greater CP and in vitro organic matter digestibility than diet samples. Observed results indicate early season grazing decreasesdiet nutrient content and forage availability compared with ungrazed pastures, suggesting that cattle were consuming both current and previous year growth.

Evaluation Of Changes In Nutritional Quality Of Corn Residue Over Time, Mandi Jones, James C. Macdonald, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson, Keith Glewen, Andrea K. Watson
Nebraska Beef Cattle Reports
Irrigated corn residue was sampled across time in order to determine changes in quality and proportion of corn residue as the plant dried and was exposed to effects of weathering. Corn plants from two hybrids were planted on two different planting dates and harvested at periodic intervals from August 2012 to December 2012. Proportions of stem, blade/sheath, husk/shank, and cob made up smaller components of total plant DM as it matured, with the largest relative reduction occurring in the blade/sheath or stem. Hybrid impacted TDN values primarily because the 119 day hybrid was less mature at the early sampling dates.

Effect Of Distillers Grains Plus Solubles And Monensin Supplementation On Grazing Steers, Tyler L. Hasenauer, Terry J. Klopfenstein, James C. Macdonald Donald, Robby G. Bondurant, Dirk B. Burken
Nebraska Beef Cattle Reports
Yearling steers rotationally grazing smooth bromegrass were individually supplemented monensin at 0 or 200 mg with modified distillers grains plus solubles (MDGS) at .05, 0.4, 0.6, and 0.8% BW. Cannulated steers continuously grazing smooth bromegrass were assigned randomly to one of two treatments: 0.4% BW MDGS supplementation with 0 or 200 mg monensin. Monensin did not affect ADG of steers supplemented MDGS ≥ 0.4% BW. Steers supplemented with monensin had a decreasein estimated average forage intakefrom 16.16 lb to 14.75 lb/OM daily.
Effects Of Replacing Corn With A Pelleted Treated Corn Stover And Distillers Grains On Intake And Total Tract Digestibility Of Finishing Diets, Jana L. Harding, Melissa L. Jolly-Breithaupt, Galen E. Erickson Erickson, James C. Macdonald
Effects Of Replacing Corn With A Pelleted Treated Corn Stover And Distillers Grains On Intake And Total Tract Digestibility Of Finishing Diets, Jana L. Harding, Melissa L. Jolly-Breithaupt, Galen E. Erickson Erickson, James C. Macdonald
Nebraska Beef Cattle Reports
A digestion study was conducted to evaluate the effects of replacing dry-rolled corn (DRC) with a pelleted feed containing treated corn stover, solubles, and distillers grains (DDG). Replacing DRC with the pelleted feed had no effect on intakes. Similarly, total tract digestibilities of DM, OM, or NDF were not affected by dietary treatment. There was a tendency for differences in average ruminalpH between treatments; however, proportions of acetate, propionate, and butyrate were not impacted. It was concluded that the DRC could be replacedwith a pelleted stover and distillers in the finishing diet without altering total tract digestion.

Nebraska Beef Cattle Reports
Carcasses of 115 Holstein steers were divided into lean, bone, internal cavity, hide, and fat tissues for analysis of P, Ca, K, Mg, and S retention. Every 28 days, five steers from each of two treatments, fed Zilmax for 20 days prior to harvest or not fed Zilmax, were harvested. There were no differences due to treatment or days on feed when mineral retention was expressed as g/100 g of protein gain. Expressing mineral retention relative to protein gain reduced variation due to rate of gain and animal size.
Supplementing Cow-Calf Pairs Grazing Smooth Bromegrass, Jason M. Warner, Annie J. Doerr, Galen E. Erickson Erickson, Rick J. Rasby, Terry J. Klopfenstein
Supplementing Cow-Calf Pairs Grazing Smooth Bromegrass, Jason M. Warner, Annie J. Doerr, Galen E. Erickson Erickson, Rick J. Rasby, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
A three-year study evaluated supplementing ethanol co-products mixed with low-quality forage to cow-calf pairs grazing smooth bromegrass as a method to replace grazed forage intake. Supplementing a 30:70 modified distillers grains plus solubles:cornstalks mixture reduced estimated grazed forage intake by approximately 40%. Doubling the stocking rate and supplementing did not impact cow or calf performance. A summer supplementation program designed to reduce grazed forage intake is a viable strategy for increasing stocking rate if forage for grazing is limited.
Effects Of Dietary Fat Source And Monensin On Methane Emissions, Vfa Profile, And Performance Of Finishing Steers, Anna C. Pesta, Andrea K. Watson, Robert G. Bondurant Bondurant, Samodha C. Fernando, Galen E. Erickson
Effects Of Dietary Fat Source And Monensin On Methane Emissions, Vfa Profile, And Performance Of Finishing Steers, Anna C. Pesta, Andrea K. Watson, Robert G. Bondurant Bondurant, Samodha C. Fernando, Galen E. Erickson
Nebraska Beef Cattle Reports
A finishing study was conducted to evaluate the effects of dietary fat source and presence or absence of monensin on performance, methane (CH4) emissions, and ruminal VFA profile of cattle. No effects on performance or VFA profile were observed. Inclusion of modified distillers grain plus solubles (MDGS) in the diet tended to increase measures of CH4 production when compared to other fat sources (corn oil or tallow), while inclusion of monensin in the finishing diet was not significant for CH4 production.

Nutrient Digestibility And Ruminal Ph Of Finishing Diets Containing Dry Milling Byproducts With And Without Oil Extraction, Melissa L. Jolly-Breithaupt, Adam L. Shreck, Jana L. Harding Harding, James C. Macdonald, Terry J. Klopfenstein, Galen E. Erickson
Nebraska Beef Cattle Reports
A metabolism trial was conducted to determine the effects of corn oil removal in condensed distillers solubles (CDS) and modified distillers grains plus solubles (MDGS) on nutrient digestibility and ruminal pH. Oil removal had no impact on DM, OM, or NDF digestibility in steers fed CDS or MDGS. However, steers fed de-oiled CDS had a lower fat digestibility than steers fed normal CDS. Average ruminal pH was lower for steers fed de-oiled MDGS than for steers fed normal MDGS, however no difference within CDS was observed.

Using Enspira To Improve Fiber Digestion, Jana L. Harding, Adam L. Shreck, Melissa L. Jolly-Breithaupt Breithaupt, Galen E. Erickson, James C. Macdonald
Nebraska Beef Cattle Reports
A metabolism study was conducted to evaluate the effects of supplementing a fibrolytic enzyme (Enspira™) on total tract digestion of a finishing diet. In situ NDF digestibilities of the corn bran, HMC, corn residue, and corn silage were not different between the treatments. Rate of digestion of the corn residue and corn silage was lower for the enzyme treatment compared to the control. Averageruminal pH was not significantly different between the two treatments. Correspondingly, there was no difference in VFA profile. There were no differences in DM, OM, NDF, ADF, or hemicellulose digestibilities between the control and enzyme treatment.
Feeding Value Of De-Oiled Wet Distillers Grains Plus Solubles Relative To Normal When Fed With Either Dry-Rolled Corn Or Steam-Flaked Corn In Beef Finishing Diets, Meredith L. Bremer, Marie E. Harris, Jake A. Hansen Hansen, Karla H. Jenkins, Matt K. Luebbe, Galen E. Erickson
Feeding Value Of De-Oiled Wet Distillers Grains Plus Solubles Relative To Normal When Fed With Either Dry-Rolled Corn Or Steam-Flaked Corn In Beef Finishing Diets, Meredith L. Bremer, Marie E. Harris, Jake A. Hansen Hansen, Karla H. Jenkins, Matt K. Luebbe, Galen E. Erickson
Nebraska Beef Cattle Reports
A 128-day finishing study utilized 328 yearling steers to determine the effects of feeding de-oiled wet distillers grains plus solubles (WDGS) in dry rolled corn (DRC) or steam-flaked corn (SFC) diets relative to normal fat WDGS. No significant interactions were observed, but cattle fed DRC had greater DMI and were less efficient than those consuming SFC. Linear improvements in ADG and F:G were observed as concentration of de-oiled WDGS increased from 0 to 35%. Numerically cattle fed normal WDGS were more efficient than cattle fed de-oiled WDGS.

Response To Increasing Concentrations Of De-Oiled Modified Distillers Grains Plus Solubles In Beef Feedlot Diets, Meredith L. Bremer, Curtis J. Bittner, Dirk B. Burken Burken, Galen E. Erickson, James C. Macdonald
Nebraska Beef Cattle Reports
A 154-day finishing study, utilizing 378 calf-fed steers, was conducted to evaluate the response to feeding increasing concentrations of de-oiled modified distillers grains plus solubles (MDGS) on cattle performance and carcass characteristics. Two additional diets were fed to compare de-oiled MDGS to normal MDGS at either 15 or 30% inclusion. Increasing concentration of de-oiled MDGS in the diet resulted in a linear improvement in F:G. When comparing 30% de-oiled to normal MDGS, there was a tendency for 3.4% improvement in F:G for cattle fed normal MDGS diets over those fed de-oiled MDGS.

Kansas Agricultural Experiment Station Research Reports
Understanding the magnitude of transmissible risk Porcine Epidemic Diarrhea Virus (PEDV)-infected feed imposes and establishing the minimum infectious dose of PEDV in a feed matrix are important components in strengthening virus prevention and control methods. In this study, an experiment was performed involving 30 crossbred, 10-d-old pigs that were used as a bioassay model for the minimum infectious dose of PEDV in feed. The PEDV was first diluted using tissue culture media to form 8 serial 10-fold dilutions. An aliquot of the original stock virus at 5.6 x 105tissue culture infectious dose/ml (TCID50/ml), each serial PEDV …

Effects Of Calf Age At Weaning On Cow And Calf Performance And Feed Utilization In An Intensive Production System, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
The effects of calf weaning age on cow and calf performance, reproduction, and feed utilization were investigated in a two-year study. Early weaning increasedcow BW in January. Pregnancy rates were not impacted by calf age at weaning. Dry matter intake (DMI) was similar between normal-weaned cow-calf pairs and early-weaned cows and calves. Feed requirements and utilization were comparable between early- and normal-weaned pairs when fed high energy diets, implying weaning decisions should be made on the basis of management rather than feed efficiency.

Nebraska Beef Cattle Reports
A growing study was conducted to evaluate the impact of alternative corn residue harvesting methods and inclusion of Rumensin® on performance and methane to carbon dioxide ratio (CH4:CO2) of steers. Use of the alternative harvesting method resulted in greater ADG and improved F:G ratio than traditionally harvested cornstalks. Rumensin increased ADG and improved DMI; however, it did not have an impacton F:G ratio. Altering the composition of baled corn residue did affect CH4:CO2, while inclusion of Rumensin, whether included in the diet on a constant or rotational basis, had no impact.

Nebraska Beef Cattle Reports
New corn residue harvesting methods were evaluated to determine the impacts of altering the proportions of plant part that are composed in a round bale. In vitro techniques were used to assess the organic matter digestibility of corn residue bale harvested with different proportions of stalks, leaves, and husk. As husk comprised a greater proportion of the bale, digestibility appeared to increase when compared with a conventional bale of cornstalks.

Digestibility Of Calcium Oxide Treated Corn Residue With De-Oiled Distillers Grains, Sarah J. Peterson, Meredith L. Bremer, Adam L. Shreck Shreck, James C. Macdonald, Galen E. Erickson
Nebraska Beef Cattle Reports
A digestion study was conducted to evaluate diets containing calcium oxide treated corn residue in combination with de-oiled distillers grains in forage based growing diets. Chemical treatment did not affect digestibility of DM, OM, or NDF. However, concentration of distillers grains did improve DM and OM digestibility. The use of chemically treated residue in combination with distillers grains in growing diets may not impact diet digestibility.

Nebraska Beef Cattle Reports
To understand the relationship betweenmicrobial community and methane, the microbial community of the rumen was examined by esophageally tubing cattle on a common diet and on 10 treatment diets. Microbial community analysis via 16S taq sequencing displayed structuring of microbial communities (Bacteria and Archaea) by diet. This study demonstrates that diet influences microbial community composition within the rumen, and the potential capacity to develop dietary interventionstrategies for methane mitigation and animal performance.

Nebraska Beef Cattle Reports
A finishing study evaluated the effectsof replacing 10, 20, or 30% corn (DM basis) with pelleted treated corn stover and distillers grains in a diet containing either 20 or 40% modified distillers grains plus solubles (MDGS) on finishing cattle performance. Steers consuming 10, 20, or 30% of the pelleted feed with 40% MDGS had equal or similar performance to the control diet with 40% MDGS. Cattle consuming 10% pelleted feed with 20% MDGS had similar efficiencies as the control diet; however, feeding the pellet at 20 or 30% of the diet DM with 20% MDGS decreased feed efficiency.
Effect Of Feeding Distillers Grains In Different Phases Of Production On The Fatty Acid Profile And Oxidation Of Frozen, Cooked Beef Links, Brandy D. Cleveland, Amy L. Redfield, James C. Macdonald Donald, Tommi F. Jones, Gary A. Sullivan
Effect Of Feeding Distillers Grains In Different Phases Of Production On The Fatty Acid Profile And Oxidation Of Frozen, Cooked Beef Links, Brandy D. Cleveland, Amy L. Redfield, James C. Macdonald Donald, Tommi F. Jones, Gary A. Sullivan
Nebraska Beef Cattle Reports
Lipid oxidation of cooked ground beef links made from cattle fed different diets and with different concentrations of added natural antioxidants was compared to evaluate product shelf life. Fatty acid composition was analyzed on raw lean, composite, and fat portions from each shoulder clod. Samples without antioxidants were the most oxidized, with no differences between other antioxidant concentrations throughout frozen storage. An increase in polyunsaturated fatty acids was found in beef when finished on modified distillers grains but did not result in increased oxidation. Therefore, the addition of natural antioxidants was effective at reducing oxidative rancidity regardless of animal diet.

A Basic Mechanism Of Beef Tenderization: Feeding Wet Distillers Grains Plus Solubles Contributes To Sarcoplasmic Reticulum Membrane Instability, Michael D. Chao, Katherine I. Domenech, Chris R. Calkins Calkins
Nebraska Beef Cattle Reports
Feeding wet distillers grains plus solubles (WDGS) could increase polyunsaturated fatty acid (PUFA) concentration in the sarcoplasmic reticulum (SR) membrane, thereby altering membrane integrity, resulting in more rapid post-rigor calcium leakage, greater enzyme activity and improved tenderness. Steers were finished on either 0% WDGS or 50% WDGS. Steaks from steers fed WDGS were more tender and had greater free calcium concentrations. Feeding WDGS also increased proportions of PUFA in SR membrane and altered SR lipid and phospholipid profiles. These findings suggest that feeding increased concentrations of WDGS in the finishing diet can possibly increase meat tenderness through the proposed mechanism.
