Feeding Elevated Levels Of Corn Silage And Mdgs In Finishing Diets, Dirk B. Burken, Brandon L. Nuttelman, Curtis J. Bittner Bittner, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

A finishing experiment evaluated substitution of corn silage and modified distillers grains with solubles (MDGS) in place of corn. The experimental arrangementwas a 2 X 2 + 1 factorial with diets containing 15 or 45% corn silage and 20 or 40% MDGS as well as a control containing 5% cornstalks and 40% MDGS. There were no interactions between corn silage and MDGS inclusion for carcass adjusted performance. As corn silage inclusion increased in the diet, there was a modest reduction in ADG and an increase in F:G. When MDGS inclusion was increased, ADG and F:G were improved. Cattle fed 40% …

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.

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.

Comparison Of Wet Or Dry Distillers Grains Plus Solubles To Corn As An Energy Source In Forage-Based Diets, Nerissa A. Ahern, Brandon L. Nuttelman, Terry J. Klopfenstein Klopfenstein, James C. Macdonald, Galen E. Erickson

Nebraska Beef Cattle Reports

Four experiments were conducted comparing wet or dry distillers grains plus solubles to each other or to corn as an energy source in forage-based diets. Diets included dry distillers grains plus solubles, wet distillers grains plus solubles or dry-rolled corn, with sorghum silage, grass hay and supplement. Data were pooled to generate ADG at differing inclusions allowing energy value of wet distillers grains plus solubles to be calculated relative to dry-rolled corn. The energy value of distillers grains plus solubles fed at 15% of diet DM was 137% and fed at 30% of the diet DM was 136% relative to …

A Nuclear Fraction Of Turnip Crinkle Virus Capsid Protein Is Important For Elicitation Of The Host Resistance Response, Sung-Hwan Kang, Feng Qu, Thomas J. Morris

Nebraska Center for Virology: Faculty Publications

The N-terminal 25 amino acids (AAs) of turnip crinkle virus (TCV) capsid protein (CP) are recognized by the resistance protein HRT to trigger a hypersensitive response (HR) and systemic resistance to TCV infection. This same region of TCV CP also contains a motif that interacts with the transcription factor TIP, as well as a nuclear localization signal (NLS). However, it is not yet known whether nuclear localization of TCV CP is needed for the induction of HRT-mediated HR and resistance. Here we present new evidence suggesting a tight correlation between nuclear inclusions formed by CP and the manifestation of HR. …

A Novel Codon-Optimized Siv Gag-Pol Immunogen For Genebased Vaccination, Catherine M. Crosby, Eric A. Weaver, Reeti Khare, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

Simian immunodeficiency virus (SIV) is a robust pathogen used in non-human primates to model HIV vaccines. SIV encodes a number of potential vaccine targets. By far the largest and most conserved protein target in SIV is its gag-pol protein that bears many epitopes to drive multivalent immune T cell responses. While gag-pol is an attractive antigen, it is only translated after a frame shift between gag and pol with the effect that gag and pol are expressed at an approximate 10/1 ratio. The codon bias of native lentiviral genes are also mismatched with the abundance of tRNAs in mammalian cells …

Effect Of Harvest Method On In Vitro Digestibility Of Corn Residues, Janessa J. Updike, Jana L. Harding, Terry J. Klopfenstein Klopfenstein, James C. Macdonald

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.

Department of Animal Science: Faculty Publications

This study examined the effects of increasing energy availability from both dextrose and lipid treatments on the proinflammatory response to LPS in Holstein steers. Steers were randomly assigned to one of three groups: saline at 0.5 ml/ kg body weight (Control) or 50% dextrose [0.5 ml/kg body weight (Dextrose) to mimic calm cattle’s response to LPS] administered immediately prior to LPS (0.5 mg/kg body weight at 0 h) or continuous lipid emulsion infusion from –1 to 6 h [Intralipid 20% (Baxter, Deerfield, IL USA); 0.5 ml/kg/hr (Lipid) to mimic temperamental cattle]. Concentrations of non-esterified fatty acids (NEFA) were greater in …

Blast-Induced Mild Traumatic Brain Injury Through Ear Canal: A Finite Element Study, Praveen Akula, Yi Hua, Linxia Gu

Department of Mechanical and Materials Engineering: Faculty Publications

Purpose The role of ear canal in transmitting blast waves to the brain is not clear. The goal of this work is to characterize the influence of ear canal on blast-induced mild traumatic brain injury through a computational approach.

Methods A three-dimensional human head model with single-side ear canal details was reconstructed from computed tomography images. The ear canal was positioned either facing the incident blast wave or facing away from the blast wave.

Results The blast wave-head interaction has demonstrated that the overpressure within the ear canal was substantially amplified when the ear directly faced the blast wave. When …

Large Dsdna Chloroviruses Encode Diverse Membrane Transport Proteins, Gerhard Thiel, Timo Greiner, David Dunigan, Anna Moroni

James Van Etten Publications

Many large DNA viruses that infect certain isolates of chlorella-like green algae (chloroviruses) are unusual because they often encode a diverse set of membrane transport proteins, including functional K+ channels and aquaglyceroporins as well as K+ transporters and calcium transporting ATPases. Some chloroviruses also encode putative ligand-gated-like channel proteins. No one protein is present in all of the chloroviruses that have been sequenced, but the K+ channel is the most common as only two chloroviruses have been isolated that lack this complete protein. This review describes the properties of these membrane-transporting proteins and suggests possible physiological functions and evolutionary histories …

Female Breakfast Skippers Display A Disrupted Cortisol Rhythm And Levated Blood Pressure, Megan Witbracht, Nancy L. Keim, Shavawn Forester, Adrianne Widaman, Kevin D. Laugero

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Chronic stress and over-activity in the hypothalamic–pituitary–adrenal (HPA) axis may link breakfast skipping and poor cardiometabolic health. Missing the first major meal of the day in rodents prolongs elevated circulating corticosterone at a time when it's normally decreasing. To extend these findings to humans, we hypothesized that habitual breakfast skippers would display a similar pattern of circulating cortisol and alterations in meal and stress-induced cortisol reactions. Normal weight to obese women aged 18–45 years old who were strictly defined as either breakfast skippers (n = 30) or breakfast eaters (n = 35) were invited to participate in our …

Curatorial Implications Of Ophyra Capensis (Order Diptera, Family Muscidae) Puparia Recovered From The Body Of The Blessed Antonio Patrizi, Monticiano, Italy (Middle Ages), Johnica J. Morrow, Diesel A. Baldwin, Leon G. Higley, Dario Piombino-Mascali, Karl J. Reinhard

Karl Reinhard Publications

The discovery of dipteran remains on mummified individuals can lead to either cause for curatorial concern or to a better understanding of the individual’s post-mortem environment. The present study analyzed insect remains associated with the body of a unique medieval mummy of religious significance, that of the Blessed Antonio Patrizi da Monticiano. A total of 79 puparia were examined and all were identified as Ophyra capensis (Diptera: Muscidae). Additionally, a desiccated moth (Lepidoptera: Tineidae) was encountered. Puparia of O. capensis would be associated with normal decomposition shortly after the death of the mummified individual, and not an infestation beginning during …

Scientific And Regulatory Policy Committee (Srpc) Review*: Interpretation And Use Of Cell Proliferation Data In Cancer Risk Assessment, Charles E. Wood, Renee R. Hukkanen, Radhakrisha Sura, David Jacobson-Kram, Thomas Nolte, Marielle Odin, Samuel M. Cohen

United States Food and Drug Administration: Publications

Increased cell proliferation is a central key event in the mode of action for many non-genotoxic carcinogens, and quantitative cell proliferation data play an important role in the cancer risk assessment of many pharmaceutical and environmental compounds. Currently, there is limited unified information on assay standards, reference values, targeted applications, study design issues, and quality control considerations for proliferation data. Here, we review issues in measuring cell proliferation indices, considerations for targeted studies, and applications within current risk assessment frameworks. As the regulatory environment moves toward more prospective evaluations based on quantitative pathway-based models, standardiza- tion of proliferation assays will …

Relationship Between Heat-Labile Enterotoxin Secretion Capacity And Virulence In Wild Type Porcine-Origin Enterotoxigenic Escherichia Coli Strains, Prageeth Wijemanne, Jun Xing, Emil M. Berberov, David H. Francis, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Heat-labile enterotoxin (LT) is an important virulence factor secreted by some strains of enterotoxigenic Escherichia coli (ETEC). The prototypic human-origin strain H10407 secretes LT via a type II secretion system(T2SS). We sought to determine the relationship between the capacity to secrete LT and virulence in porcine-origin wild type (WT) ETEC strains. Sixteen WT ETEC strains isolated from cases of severe diarrheal disease were analyzed by GM1ganglioside enzyme- linked immunosorbent assay tomeasure LT concentrations in culture supernatants. All strains had detectable LT in supernatants by 2 h of culture and 1 strain, which was particularly virulent in gnotobiotic piglets (3030-2), had …

Temperatures Of Storage Areas In Large Animal Veterinary Practice Vehicles In The Summer And Comparison With Drug Manufacturers’ Storage Recommendations, Jeff D. Ondrak, Meredyth L. Jones, Virginia R. Fajt

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Large animal veterinarians carry drugs in their practice vehicles in storage areas that are not typically refrigerated. The most common upper limits of manufacturers’ storage temperatures for United States (U.S.)-approved non-refrigerated drugs are 25 or 30 °C. Because ambient temperatures in many locations in the U.S. exceed these temperatures during the summer, we measured storage area temperatures over 4 months in the summer of 2013 to evaluate the extent to which labeled storage temperatures are exceeded.

Methods: A convenience sample of 12 vehicles from 5 central Texas practices and 12 vehicles from 4 south central Nebraska practices was …

Whole-Genome Sequencing Of Kaposi’S Sarcoma-Associated Herpesvirus From Zambian Kaposi’S Sarcoma Biopsy Specimens Reveals Unique Viral Diversity, Landon Olp, Adrien Jeanniard, Clemence Marimo, Charles Wood

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the etiological agent for Kaposi’s sarcoma (KS). Both KSHV and KS are endemic in sub-Saharan Africa where approximately 84% of global KS cases occur. Nevertheless, whole-genome sequencing of KSHV has only been completed using isolates from Western countries—where KS is not endemic. The lack of whole-genome KSHV sequence data from the most clinically important geographical region, sub-Saharan Africa, represents an important gap since it remains unclear whether genomic diversity has a role on KSHV pathogenesis. We hypothesized that distinct KSHV genotypes might be present in sub-Saharan Africa compared to Western countries. Using a KSHV-targeted enrichment …

Quantitation Of Ortho-Cresyl Phosphate Adducts To Butyrylcholinesterase In Human Serum By Immunomagnetic-Uhplc-Ms/Ms, Darryl Johnson, Melissa D. Carter, Brian S. Crow, Samantha L. Isenberg, Leigh Ann Graham, H. Akin Erol, Caroline M. Watson, Brooke G. Pantazides, Marcel J. Van Der Schans, Jan P. Langenberg, Daan Noort, Thomas A. Blake, Jerry D. Thomas, Rudolph C. Johnson

United States Public Health Resources

Tri-ortho-cresyl phosphate (ToCP) is an anti-wear, flame retardant additive used in industrial lubricants, hydraulic fluids and gasoline. The neurotoxic effects of ToCP arise fromthe liver-activated metabolite 2-(o-cresyl)-4H-1,3,2-benzodioxaphosphoran-2-one (cresyl saligenin phosphate or CBDP),which inhibits esterase enzymes including butyrylcholinesterase (BChE). Following BChE adduction, CBDP undergoes hydrolysis to form the aged adduct ortho-cresyl phosphoserine (oCP-BChE), thus providing a biomarker of CBDP exposure. Previous studies have identified ToCP in aircraft cabin and cockpit air, but assessing human exposure has been hampered by the lack of a laboratory assay to confirm exposure. This work presents the development of an immunomagnetic- UHPLC-MS/MS method for the quantitation …

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.

Effect Of Post-Weaning Management And Age At Weaning On Calf Growing And Finishing Performance, Jason M. Warner, Curtis J. Bittner, Karla H. Jenkins Jenkins, Rick J. Rasby, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

The impact of post-weaning management system and calf age at weaning on growing and finishing performance was evaluated. During the growing phase, cattle in the fast-track system had improved intake, gain, and feed conversion. Although initial finishing weight was similar between systems, slow-track cattle had greater intake, gain, final body weight, and carcass weight. While the impact of age at weaning was negligible, the improvement in finishing performance for slow-track cattle demonstrates the value of different management systems.

Estimation Of British- And Continental-Specific Heterosis Effects For Birth, Weaning, And Yearling Weight In Cattle, Lauren N. Schiermiester, R. Mark Thallman, Larry A. Kuehn Kuehn, Matthew L. Spangler

Nebraska Beef Cattle Reports

Heterosis, assumed proportional to expected breed heterozygosity, was calculated for 6,834 individuals with birth, weaning, and yearling weight records from Cycle VII of the U.S. Meat Animal Research Center Germplasm Evaluation Program. Heterosis was further estimated by proportions of British x British (BxB), British x Continental (BxC), and Continental x Continental (CxC) crosses. Estimates of BxB, BxC, and CxC heterosis were significant for weaning and yearling weight. This study illustrated that differences among biological types exist and provide an opportunity to utilize specific breeds and exploit heterosis in a crossbreeding system to achieve production goals.

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 …

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.

Comparison Of Commercial Lick Tubs To Distillers Grains Supplementation For Calves Grazing Corn Residue, Mandi Jones, James C. Macdonald, Galen E. Erickson Erickson, Terry J. Klopfenstein, Kathleen R. Brooks, Dirk B. Burken, Robby Bondurant, Andrea K. Watson

Nebraska Beef Cattle Reports

Steer calves grazing irrigated corn residue were supplemented dried distillers grains plus solubles (DGS) or allowedcontinuous access to a commercial lick tub. Dried DGS was fed at 2.94 lb/steer/day and the lick tubs were consumed at 2.04 lb/steer/day (DM basis). Gain was greater for cattle supplemented with dried DGS (1.36 lb/day) compared to those with access to lick tubs (0.83 lb/day). Supplement efficiency varied between calves receiving dried DGS (46%) and those with continuous access to the lick tub (43%) when expressed on a DM basis. Values for dried DGS supplementation (48%) were not different for supplement efficiencyon an OM …

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.

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 Processing Treated Corn Stover And Distillers Grains On Performance Of Growing Cattle, Jana L. Harding, Curtis J. Bittner, Dirk B. Burken Burken, Galen E. Erickson, James C. Macdonald

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.
