Experience Improves The Reliability Of Subjective Measurements Of Temperament In Beef Cattle, Jaime T. Praham, Amy E. Tanner, Mark L. Wahlberg Wahlberg, W. S. Swecker Jr., Ronald M. Lewis Jan 2018

Experience Improves The Reliability Of Subjective Measurements Of Temperament In Beef Cattle, Jaime T. Praham, Amy E. Tanner, Mark L. Wahlberg Wahlberg, W. S. Swecker Jr., Ronald M. Lewis

Nebraska Beef Cattle Reports

Reliability of experienced and inexperienced observers when assessing the behavior of cattle when restrained in a squeeze chute (chute score), and when exiting the chute (exit score), was compared. Overall, experienced observers had higher reliability than inexperienced observers. Increasing the number of individuals scoring an animal decreased the degree of agreement. However, within an acceptable tolerance for difference in scores, such disagreement may be beneficial; it allows for subtlety in interpretations of temperament, which when averaged, may better reflect docility. Reliabilities were higher for exit score than chute score. This may reflect the complexity of the trait being evaluated, with …

Antimicrobial Interventions And Application Time Effects On Ground Beef Quality, Ashley R. Mccoy, Dennis E. Burson, Gary A. Sullivan Sullivan

Nebraska Beef Cattle Reports

Small business meat processors can use organic acid antimicrobial interventions to control Shiga toxin-producing E. coli (STEC) when producing ground beef; however, many small producers are concerned about the impact on ground beef quality. The effects of two commonly used organic acids, lactic acid and peroxyacetic acid, were evaluated at short (15 seconds) or extended (3 minutes) raw material dip times on ground beef quality parameters. Beef trim dipped in lactic acid for 3 minutes had a reduction in total aerobic bacteria plate count, but also increased ground beef discoloration and lipid oxidation during retail display. Use of a shorter …


Steer Performance Grazing Corn Residue And Supplemented With Modified Distillers Grains Plus Solubles With Or Without Urea, Robert M. Jones, Robby G. Bondurant, F. Henry Hilscher Hilscher, Jim C. Macdonald Jan 2018

Steer Performance Grazing Corn Residue And Supplemented With Modified Distillers Grains Plus Solubles With Or Without Urea, Robert M. Jones, Robby G. Bondurant, F. Henry Hilscher Hilscher, Jim C. Macdonald

Nebraska Beef Cattle Reports

A growing study was conducted to evaluate the effects of supplementing growing calves grazing corn residue with modified distillers grains plus solubles (MDGS; 3 or 5 lb/d) and with or without urea on growth performance. There were no significant MDGS × urea inclusion interactions observed. Urea inclusion level (0 and 0.12 lb/d) did not affect supplemental intake, ADG, or ending BW. Steers fed 5 lb of MDGS had an increased ADG and a heavier ending BW compared to steers fed 3 lb MDGS daily. Supplemental urea is not necessary when supplementing at least 3 lb MDGS to steers grazing corn …

Evaluation Of Corn Distillers Solubles On Growing Steer Performance, Benjamin H. Hansen, Robert G. Bondurant, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald

Nebraska Beef Cattle Reports

A growing study evaluated increasing inclusions of corn distillers solubles (CDS) at 10, 20, 30, and 40%, or increasing wet distillers grains plus solubles (WDGS) at 10, 20, 30, and 40% compared to a corn control. Corn was replaced by CDS or WDGS in each forage-based diet. Increasing CDS resulted in a quadratic increase for both DMI and F:G. Increasing WDGS linearly increased both DMI and ADG with no effect on F:G. The energy value of CDS is less than that of corn, whereas WDGS had an energy value similar to corn in growing diets with 50% brome hay. A …

The Effect Of Harvest Method And Ammoniation Of Corn Residue On Growing Calf Performance, Ashley C. Conway, Robert G. Bondurant, F. Henry Hilscher Hilscher, James C. Macdonald, Terry J. Klopfenstein, Mary Drewnoski

Nebraska Beef Cattle Reports

A growing trial was conducted to determine the effect of feeding baled corn residue harvested using three different methods, with and without ammoniation of the residue. Residue harvested with the New Holland Cornrower™ with two rows of chopped stem added to the windrow resulted in a 9% increase in ADG compared to conventional rake and bale harvest or turning off the combine spreader and baling tailing. Ammoniation of residue increased ADG 67% (increase of 1.1 lb/d) over non-ammoniated residue. Feed efficiency was not affected by harvest method, but ammoniation decreased F:G by 13% compared to cattle fed non-ammoniated residue. Although …

Department of Agronomy and Horticulture: Faculty Publications

Genomic prediction (GP) is now routinely performed in crop plants to predict unobserved phenotypes. The use of predicted phenotypes to make selections is an active area of research. Here, we evaluate GP for predicting grain yield and compare genomic and phenotypic selection by tracking lines advanced. We examined four independent nurseries of F3:6 and F3:7 lines trialed at 6 to 10 locations each year. Yield was analyzed using mixed models that accounted for experimental design and spatial variations. Genotype-by-sequencing provided nearly 27,000 high-quality SNPs. Average genomic predictive ability, estimated for each year by randomly masking lines as missing …


Women’S Work? The Relationship Between Farmwork And Gender Self-Perception, Jolene Smyth, Alexis Swendener, Emily Kazyak Jan 2018

Women’S Work? The Relationship Between Farmwork And Gender Self-Perception, Jolene Smyth, Alexis Swendener, Emily Kazyak

Department of Sociology: Faculty Publications

Women have long been involved in agricultural production, yet farming and ranching have been associated with masculinity and men. In recent years women have become more involved and more likely to take active and equal roles on farms and ranches and thus increasingly are doing tasks that have been associated with masculinity. Prior work indicates that women are perceived by others as more masculine when they do these tasks, but less work has focused on the association between women’s involvement in farming and women’s own perceptions of their gender (i.e., how masculine or feminine they feel). Using 2006 survey data …


Intermolecular Rna Recombination Occurs At Different Frequencies In Alternate Forms Of Brome Mosaic Virus Rna Replication Compartments, Hernan Garcia-Ruiz, Arturo Diaz, Paul Ahlquist Jan 2018

Intermolecular Rna Recombination Occurs At Different Frequencies In Alternate Forms Of Brome Mosaic Virus Rna Replication Compartments, Hernan Garcia-Ruiz, Arturo Diaz, Paul Ahlquist

Department of Plant Pathology: Faculty Publications

Positive-strand RNA viruses replicate their genomes in membrane-bound replication compartments. Brome mosaic virus (BMV) replicates in vesicular invaginations of the endoplasmic reticulum membrane. BMV has served as a productive model system to study processes like virus-host interactions, RNA replication and recombination. Here we present multiple lines of evidence showing that the structure of the viral RNA replication compartments plays a fundamental role and that recruitment of parental RNAs to a common replication compartment is a limiting step in intermolecular RNA recombination. We show that a previously defined requirement for an RNA recruitment element on both parental RNAs is not to …

Department of Plant Pathology: Faculty Publications

Background: Maize lethal necrosis is caused by a synergistic co-infection of Maize chlorotic mottle virus (MCMV) and a specific member of the Potyviridae, such as Sugarcane mosaic virus (SCMV), Wheat streak mosaic virus (WSMV) or Johnson grass mosaic virus (JGMV). Typical maize lethal necrosis symptoms include severe yellowing and leaf drying from the edges. In Kenya, we detected plants showing typical and atypical symptoms. Both groups of plants often tested negative for SCMV by ELISA. Methods: We used next-generation sequencing to identify viruses associated to maize lethal necrosis in Kenya through a metagenomics analysis. Symptomatic and asymptomatic leaf samples …


Susceptibility Genes To Plant Viruses, Hernan Garcia Ruiz Jan 2018

Susceptibility Genes To Plant Viruses, Hernan Garcia Ruiz

Department of Plant Pathology: Faculty Publications

Plant viruses use cellular factors and resources to replicate and move. Plants respond to viral infection by several mechanisms, including innate immunity, autophagy, and gene silencing, that viruses must evade or suppress. Thus, the establishment of infection is genetically determined by the availability of host factors necessary for virus replication and movement and by the balance between plant defense and viral suppression of defense responses. Host factors may have antiviral or proviral activities. Proviral factors condition susceptibility to viruses by participating in processes essential to the virus. Here, we review current advances in the identification and characterization of host factors …

Genomic selection (GS) by selecting lines prior to field phenotyping using genotyping data has the potential to enhance the rate of genetic gains. Genotype × environment (G × E) interaction inclusion in GS models can improve prediction accuracy hence aid in selection of lines across target environments. Phenotypic data on 320 chickpea breeding lines for eight traits for three seasons at two locations were recorded. These lines were genotyped using DArTseq (1.6 K SNPs) and Genotyping-by-Sequencing (GBS; 89 K SNPs). Thirteen models were fitted including main effects of environment and lines, markers, and/or naïve and informed interactions to estimate prediction …


Gene Expression Profiling Of Iron Deficiency Chlorosis Sensitive And Tolerant Soybean Indicates Key Roles For Phenylpropanoids Under Alkalinity Stress, Brian M. Waters, Keenan Amundsen, George L. Graef Jan 2018

Gene Expression Profiling Of Iron Deficiency Chlorosis Sensitive And Tolerant Soybean Indicates Key Roles For Phenylpropanoids Under Alkalinity Stress, Brian M. Waters, Keenan Amundsen, George L. Graef

Department of Agronomy and Horticulture: Faculty Publications

Alkaline soils comprise 30% of the earth and have low plant-available iron (Fe) concentration, and can cause iron deficiency chlorosis (IDC). IDC causes soybean yield losses of $260 million annually. However, it is not known whether molecular responses to IDC are equivalent to responses to low iron supply. IDC tolerant and sensitive soybean lines provide a contrast to identify specific factors associated with IDC.We used RNA-seq to compare gene expression under combinations of normal pH (5.7) or alkaline pH (7.7, imposed by 2.5mM bicarbonate, or pH 8.2 imposed by 5mM bicarbonate) and normal (25μM) or low (1μM) iron conditions from …


European Spaces And The Roma: Denaturalizing The Naturalized In Online Reader Comments, Theresa Catalano, Grace E. Fielder Jan 2018

European Spaces And The Roma: Denaturalizing The Naturalized In Online Reader Comments, Theresa Catalano, Grace E. Fielder

Department of Teaching, Learning, and Teacher Education: Faculty Publications

With the entry of several Eastern European nations into the European Union (EU), a “third” space has developed in the discourse for nations perceived as not fully integrated “inside” the EU system. This article investigates the construction of this “third space” in the resultant “moral panic” about undesired immigration from other EU countries and its potential drain on the social services of the United Kingdom and links it to Euroskeptic discourse in British media. The article uses construal operations from cognitive linguistics combined with critical discourse studies as a way of denaturalizing the discourse in online comments that focus on …

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

House flies (Musca domestica) are worldwide agricultural pests with estimated control costs at $375 million annually in the U.S. Non-target effects and widespread resistance challenge the efficacy of traditional chemical control. Double stranded RNA (dsRNA) has been suggested as a biopesticide for M. domestica but a phenotypic response due to the induction of the RNAi pathway has not been demonstrated in adults. In this study female house flies were injected with dsRNA targeting actin-5C or ribosomal protein (RP) transcripts RPL26 and RPS6. Ovaries showed highly reduced provisioning and clutch reductions of 94±99% in RP dsRNA treated flies but …

Detection Of Exogenous Double-Stranded Rna Movement In In Vitro Peanut Plants, P. C. Faustinelli, I. L. Power, R. S. Arias

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

New technologies are needed to eliminate mycotoxins and/or fungal pathogens from agricultural products. RNA interference (RNAi) has shown potential to control fungi associated with crops. In RNAi, double-stranded RNA (dsRNA) targets homologous mRNA for cleavage, and can reach the mRNA of pathogens in contact with the plant. The key element in this process is the movement of RNA signals cell-to-cell and over long distances within the plant, and between host plants and parasites.

• In this study, we selected a regulatory gene in the aflatoxin biosynthesis pathway, aflS/ aflR, necessary for the production of aflatoxins in Aspergillus spp. We …

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

Triclosan is frequently used for its antimicrobial properties and has been detected in human serum, urine, and breast milk. Animal and molecular studies have shown that triclosan exerts a wide range of adverse health effects at both high (ppm) and low (ppb) concentrations. Since triclosan is of growing concern to human and environmental health, there is a need to improve extraction procedures and to study additional effects from triclosan exposure. In this study, we have improved triclosan extraction from breast milk by using salt (MgSO4) to reduce emulsion formation and increase water polarity and water (~80%) to enhance the overall …

In the last decades, many regional and country-wide control programmes for Johne’s disease (JD) were developed due to associated economic losses, or because of a possible association with Crohn’s disease. These control programmes were often not successful, partly because management protocols were not followed, including the introduction of infected replacement cattle, because tests to identify infected animals were unreliable, and uptake by farmers was not high enough because of a perceived low return on investment. In the absence of a cure or effective commercial vaccines, control of JD is currently primarily based on herd management strategies to avoid infection of …

A Simple And Scalable Hydrogel-Based System For Culturing Protein-Producing Cells, Qiang Li, Qiaofeng Wang, Ou Wang, Kaifeng Shao, Haishuang Lin, Yuguo Lei

Department of Chemical and Biomolecular Engineering: Faculty Publications

Recombinant protein therapeutics have become important components of the modern medicine. Majority of them are produced with mammalian cells that are cultured either through adherent culturing, in which cells are cultured on substrates, or suspension culturing, in which cells are suspended and cultured in agitated cell culture medium in a culture vessel. The adherent cell culturing method is limited by its low yield. In suspension culturing, cells need extensive genetic manipulation to grow as single cells at high density, which is time and labor-consuming. Here, we report a new method, which utilizes a thermoreversible hydrogel as the scaffold for culturing …

The Interface Between Wheat And The Wheat Curl Mite, Aceria Tosichella, The Primary Vector Of Globally Important Viral Diseases, Anna Skoracka, Brian G. Rector, Gary L. Hein

Department of Entomology: Faculty Publications

Wheat production and sustainability are steadily threatened by pests and pathogens in both wealthy and developing countries. This review is focused on the wheat curl mite (WCM), Aceria tosichella, and its relationship with wheat. WCM is a major pest of wheat and other cereals and a vector of at least four damaging plant viruses (Wheat streak mosaic virus, High plains wheat mosaic virus, Brome streak mosaic virus, and Triticum mosaic virus). The WCM–virus pathosystem causes considerable yield losses worldwide and its severity increases significantly when mixed-virus infections occur. Chemical control strategies are largely ineffective because WCM occupies …

Department of Entomology: Faculty Publications

Societal dependence on insects for pollination of agricultural crops has risen amidst concerns over pollinator declines. Habitat loss and lack of forage have been implicated in the decline of both managed and native pollinators. Land use changes in the Northern Great Plains of the US, a region supporting over 1 million honey bee colonies annually, have shifted away from historical grassland ecosystems bees rely on for forage toward landscapes dominated by corn, soybeans, and other row crops. We investigated how land use impacts honey bee colony population size during the growing season and subsequent colony population size for almond pollination …
