The Effects Of Source And Amount Of Nitrite On Quality Characteristics Of All-Beef Frankfurters, Eric Miller, Chad G. Bower, Amy L. Redfield Redfield, Gary A. Sullivan
Nebraska Beef Cattle Reports
In an effort to meet consumers’ demand for foods with more natural ingredients, processors have begun manufacturing meat products cured with natural nitrite sources. The objective of this study was to evaluate the quality characteristics of all-beef frankfurters cured with traditional or alternative sources of nitrite and using equivalent amounts of nitrite. Frankfurters cured with alternative sources of nitrite had a slightly darker, less red exterior and slightly more yellow interior than those containing sodium nitrite. No differences were observed for pH or water activity. Both curing methods can be used to manufacture all-beef frankfurters with similar characteristics when using …

Effect Of Diet On The Rumen Microbial Community Composition Of Growing Cattle And The Role It Plays In Methane Emissions, Allison L. Knoell, Christopher L. Anderson, Anna C. Pesta Pesta, Galen E. Erickson, Terry J. Klopfenstein, Samodha C. Fernando
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.

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.

Nebraska Beef Cattle Reports
Nebraska Sandhills subirrigated meadow pastures were used to measure the effects of grazing on forage nutrient content in summer pastures. Non-grazed pastures had greater diet CP content than grazed pastures early in the grazing season. By late July, grazed vs. non-grazed pastures did not differ in diet CP content. Non-grazed pastures had greater in vitro organic matter disappearance compared with grazed pastures from late July through September; however, early summer pastures were not affected. Observed results indicate the greatest differences in nutrient content between grazed and non-grazed meadow pastures occur early and late in the grazing season when the majority …

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.

Efficacy Of Bovatec 2.2 Mineral Blocks For Cattle Grazing Crested Wheatgrass Pastures, Karla H. Jenkins, Jacob A. Hansen, Matt K. Luebbe Luebbe
Nebraska Beef Cattle Reports
A grazing study was conducted to determine if providing Bovatec® in a trace mineralized salt block would improve cattle performance over cattle provided a trace mineralized salt block without an ionophore while maintaining block consumption below 2 oz/head/day. Average daily block intake was 1.40 and 1.25 oz/day for the Bovatec and control cattle, respectively. Lasalocid consumption was 193 mg/head/day. Although cattle consuming the Bovatec block gained 5% more than the control cattle, this was not significant (1.75 vs 1.67 lb/day, respectively). Supplying an ionophore through a self-feeding block may not improve gain compared to supplying mineral alone in a self-feeding …

Nebraska Beef Cattle Reports
A study evaluated the effects of replacinga diet consisting of 60% corn stover, 18% solubles, and 18% distillers grains with a complete pelleted feed containing calcium oxide (CaO) treated corn stover and distillers grains on growing cattle performance. The pelleted feed was either pair-fed to the control treatment or fed ad libitum. There were no differences in ending BW, ADG, or F:G between the control and pair-fed treatment. Feeding the pellet ad libitum resulted in greater DMI and ADG; however, the cattle had greater F:G. The pellet has 98% the feeding value of the control treatment.

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.

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.

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.

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
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.

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.
