Feeding Corn Milling Co-Products To Feedlot Cattle, 3rd Edition, Galen E. Erickson, Crystal D. Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Two primary types of milling processes currently exist, resulting in quite different feed products. These processing plants produce and market a variety of feed products, but in general, the dry milling process produces distillers grains plus solubles (DGS), and the wet milling process produces corn gluten feed (CGF). These feeds can be marketed as wet feeds, or they can be dried and marketed as either dry corn gluten feed (DCGF) or dry distillers grains (DDG) with or without solubles.

For the purposes of this report, wet corn gluten feed (WCGF), wet distillers grains plus solubles (WDGS), DCGF and dried …

The Effects Of Phytase And An Enzyme Combination In Moderate And Low Nutrient Dense Diets In Laying Hens, Dana L. Hahn

Department of Animal Science: Dissertations, Theses, and Student Research

The objective was to test the addition of Avizyme ® 1502, a blend of protease, amylase and xylanase (Danisco, UK Ltd.) and a phytase in laying hens fed corn-soy diets containing Dried Distillers Grains (DDGS), Meat and Bone Meal (MBM). 384 Hy-Line W-36 laying hens were used in this study from 24-52 weeks of age. There were 12 replicate pens with 4 hens per pen, thus 96 pens in total. The study consisted of 8 dietary treatments arranged in a 2x2x2 factorial design. The factors were: diet (containing DDGS or MBM), metabolizable energy (ME) level 2930 Kcal/kg (Phase 1), 2880 …

A Naturalistic Study Of Exercise Adherence Among A Community Based Sample At A Fitness Facility, Felicia M. Johnson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study aimed at investigating the factors predictive of exercise for short-term (i.e., at least six months) and long-term (i.e., at least one year) adherence at a fitness facility. Exercise adherence, defined through the Transtheoretical Model (TTM) as the maintenance stage of change, and frequency of participation in exercise were measured through member utilization of the fitness facility as it occurred in the participant’s natural setting without interference of the researcher. Each time a member entered the exercise facility they scanned their member card and their attendance was automatically recorded into the membership computer system. Fitness Planning & Positive Appraisal, …

Development Of An Enzyme-Linked Immunosorbent Assay (Elisa) For The Detection Of Pistachio Residues In Processed Foods, Pei Wen Lim

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Pistachios (Pistacia vera) are popular snacks and consumption of pistachios is notably increasing due to their usage as ingredients for confections, ice cream, and baked goods. The increased consumption of pistachios may lead to a higher frequency of allergic sensitization and an increased prevalence of allergic reactions to pistachios. Trace amounts of undeclared pistachio allergens can pose serious health risks for food-allergic consumers, including severe anaphylactic reactions. A highly sensitive analytical method, sandwich-type enzyme-linked immunosorbent assay (ELISA) is applied as a critical tool for food manufacturers and food scientists to detect minute amounts of allergenic food residues in …

Time, Temperature And Species Interactions In A Duckweed–Herbivore Mesocosm, Ian Waterman

School of Biological Sciences: Dissertations, Theses, and Student Research

Species interactions within a community are impacted by a variety of abiotic factors. Temperature is known to alter population dynamics such that direct and indirect interactions between populations within a community are affected. Here I investigate the effect of temperature change on species interactions within a duckweed-herbivore mesocosm. Multiple communities were constructed, from a single population of duckweed, to two populations of duckweed consumed by aphids. In the one-predator two-prey web we predicted mutually positive indirect effects between duckweed populations during the first generation of growth. As aphid populations respond numerically to more abundant prey, mutually negative and asymmetric indirect …

Identification Of Sources Of Rhizoctonia Root Rot Resistance In Common Bean And Mapping A New Source Of Bean Rust Resistance From The Tertiary Gene Pool Of Common Bean, Pamela A. Peña-Perdomo

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

An efficient screening method was developed and used to identify bean lines resistant to Rhizoctonia Root Rot caused by Rhizoctonia solani Kuhn. Two sets of 163 and 111 lines previously evaluated for drought tolerance at Mitchell, NE and Isabela, PR were evaluated for Rhizoctonia Root Rot resistance under greenhouse conditions. This root rot data was also correlated with yield under drought stress and non stress conditions. In the first set of lines the rhizoctonia mean score ranged from 1.7 to 3.9; and in the second set the rhizoctonia mean score was between 2.6 and 5.7. There was no significant correlation …

Understanding Social Capital Development And Academic Attainment Of Mobile Students, Julie A. Gaddie

Department of Educational Administration: Dissertations, Theses, and Student Research

The United Sates has a long history of searching for utopian possibilities of public school, amidst a steady stream of population mobility. Horace Mann proclaimed that schools would be able to assimilate the millions of immigrants arriving during the late 1700’s. He promised that schools could end poverty, crime and social injustice. Today, public schools continue to serve a revolving door of students and most agree there may be little that can be done to prevent student mobility amidst the complexities of a growing global economy, immigration and the increase in children living in poverty. The challenge for the public …

Cover Me, Soyna Huber

University of Nebraska Press: Sample Books and Chapters

Growing up in middle-class middle America, Sonya Huber viewed health care as did most of her peers: as an inconvenience or not at all. There were braces and cavities, medications and stitches, the family doctor and the local dentist. Finding herself without health insurance after college graduation, she didn’t worry. It was a temporary problem. Thirteen years and twenty-three jobs later, her view of the matter was quite different. Huber’s irreverent and affecting memoir of navigating the nation’s health-care system brings an awful and necessary dose of reality to the political debates and propaganda surrounding health-care reform. “I look like …

On The Road Again Consumptives Traveling For Health In The American West, 1840-1925, Jeanne Abrams

Great Plains Quarterly (through 2013)

From the mid-nineteenth century through the first decades of the twentieth century, hundreds of thousands of health seekers, on the advice of their physicians, family members, or popular advertisements, took to the road to "chase the cure" for tuberculosis, the most dreaded disease of the era. Indeed, tuberculosis, also commonly known as consumption or "the White Plague," held the dubious distinction of being the leading cause of death in nineteenth century America. In the first years of the twentieth century 150,000 Americans died of it yearly, and more than ten times that number were afflicted with the disease.¹ Whether …

Department of Food Science and Technology: Faculty Publications

The human oral cavity contains a number of different habitats, including the teeth, gingival sulcus, tongue, cheeks, hard and soft palates, and tonsils, which are colonized by bacteria. The oral microbiome comprises over 600 prevalent taxa at the species level, with distinct subsets predominating at different habitats. The oral microbiome has been extensively characterized by cultivation and culture-independent molecular methods such as 16S rRNA cloning. Unfortunately, the vast majority of unnamed oral taxa are referenced by clone numbers or 16S rRNA GenBank accession numbers, often without taxonomic anchors. The first aim of this research was to collect 16S rRNA gene …

Growth Of Lactic Acid Bacteria: Influence Of Protocooperation, Bacteriophage Infection, And Prebiotic Carbohydrates, Caitlin D. Goin

School of Biological Sciences: Dissertations, Theses, and Student Research

Lactic acid bacteria are a vital part of the fermented food industry and are the subject of much interest and research. Industry is especially interested in using modern molecular approaches to maintain and improve selected strains; several industrial uses could be improved by closer investigation, namely the protocooperation of S. thermophilus and L. bulgaricus, the role of CRISPRs in phage resistance, and the utilization of prebiotic carbohydrates. Questions such as what genes and pathways are shared during milk fermentation between S. thermophilus and L. bulgaricus, when and what genes are active during bacteriophage infection, and how and where …

Factors Influencing Long-Term Population Dynamics Of Pronghorn (Antilocapra Americana): Evidence Of An Allee Effect, Justin D. Hoffman, Hugh H. Genoways, Rachel R. Jones

University of Nebraska State Museum: Mammalogy Papers

Populations of pronghorn (Antilocapra americana) are subjected to multiple forms of density-dependent and density-independent regulation. Little is known about the combined effects of these variables across multiple populations throughout the landscape. The objectives of this study were to examine long-term trends in density and recruitment in pronghorn and to assess how different forms of regulation influence these trends. We used multiple density-dependent and density-independent explanatory variables in a model selection process to explain variation in pronghorn density and July fawn : doe ratios from 1955 to 1993 in 4 pronghorn management units in Nebraska. We also investigated levels …

Refinement Of Biomarker Pentosidine Methodology For Use On Aging Birds, Crissa K. Cooey, Jesse A. Fallon, Michael L. Avery, James T. Anderson, Elizabeth A. Falkenstein, Hillar Klandorf

United States Department of Agriculture Wildlife Services: Staff Publications

There is no reliable method for determining age for most species of long-lived birds. Recent success using the skin chemical pentosidine as a biomarker has shown promise as an aging tool for birds. Pentosidine levels have been determined only from the breast tissue of carcasses, and we sought to refine the procedure with respect to biopsy size and location for safe and effective use on living birds. We compared pentosidine concentrations in 4 skin-size samples (4, 6, 8, and 20-mm diameter biopsies) from the breast of black vulture (Coragyps atratus) carcasses. We also compared pentosidine levels from breast …

Evaluation Of Rhodamine B As A Biomarker For Raccoons, Tricia L. Fry, Todd C. Atwood, Mike R. Dunbar

United States Department of Agriculture Wildlife Services: Staff Publications

The USDA/APHIS/Wildlife Services (WS) oral rabies vaccination program uses tetracycline, a broad-spectrum antibiotic and relatively reliable biomarker, to quantify vaccinebait uptake by raccoons (Procyon lotor). However, obtaining samples (e.g., bone or teeth) to assess tetracycline uptake is highly invasive, and sample preparation can be expensive. By contrast, rhodamine B, a commercially available dye, is absorbed systemically in growing tissues, including hair and whiskers, and can be observed under ultraviolet (UV) light as fluorescent orange bands. Our goal was to evaluate whether rhodamine B can be used as a biomarker to monitor bait uptake by raccoons. We began by …

Sugar Beet Fertilization, Gary W. Hergert

Panhandle Research and Extension Center

Global sugar beet production spans diverse regions and a wide range of climatic and agroecological regions from rainfed to irrigated production which presents unique management challenges. Sound nutrient management now and into the future must be balanced between production efficiency and managing to have less impact on the environment. N management continues to improve with more precise N rates. Soil testing for N supplying capability plus residual N will need to be increased to enhance productivity and N use efficiency. Newer cultivation techniques, N placement and timing can also fine tune N rates. In irrigated areas, improvements in N management …

Susceptibility Of Isofamilies Of Spodoptera Frugiperda (Lepidoptera: Noctuidae) To Cry1ac And Cry1fa Proteins Of Bacillus Thuringiensis, Carlos A. Blanco, Maribel Portilla, Juan Luis Jurat-Fuentes, Jaime F. Sanchez, Diego Viteri, Paulina Vega-Aquino, Antonio P. Teran-Vargas, Ausencio Azuara-Dominguez, Juan D. Lopez Jr., R. S. Arias, Yu-Cheng Zhu, David Lugo-Barreras, Ryan Jackson

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

The fall armyworm, Spodoptera frugiperda (J. E. Smith), is one of the most important insect pests on the American continent. Its control has relied primarily on multiple applications of insecticides that can amount to 1,000 g of active ingredient per hectare on some of approximately 30 crops the insect damages. The use of genetically engineered crops that express Bacillus thuringiensis (Bt) Berliner toxins, Bt-corn, Zea mays L.; and Bt-cotton, Gossypium hirsutum L.; are other ways to control this insect. However, fall armyworm is one of the Lepidoptera species least susceptible to Bt proteins, and a case of high tolerance to …

My Life In Biology: Paul A. Johnsgard, Paul A. Johnsgard

Papers in Ornithology

I was born in 1931 in the very small town of Christine, North Dakota, on the Red River about 20 miles south of Fargo. My granddad owned a general store there, and my father worked in that store for as long as we lived in Christine, which was until 1939. These were the Depression years, and my major memories of that time are of hot dusty streets in the summer and bitterly cold winters, when I had to walk across town to school. ...

A Pilot Study Of The Relationship Of Calcium Intake And Frequency Of Injuries In High School Athletes, Jeffrey K. Ebert

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Little information is available related to adolescent calcium intake and relationships with injuries they might suffer from sport participation. To determine calcium intake of high school athletes, to assess their self reported injury rates, and to examine the relationship between the two over a 12 month period of time. Participants received a questionnaire at their school and completed it anywhere they found convenient. Adolescent athletes in the Lincoln Public School system (n=43) that participated in at least one sport in the past year. Four age groups participated in the study with sixteen year olds having a significantly higher calcium intake …

Plant Sterol And Stanol Substrate Specificity Of Pancreatic Cholesterol Esterase, Andrew W. Brown, Jiliang Hang, Patrick H. Dussault, Timothy P. Carr

Patrick Dussault Publications

Consumption of plant sterols or stanols (collectively referred to as phytosterols) and their esters results in decreased lowdensity lipoprotein cholesterol, which is associated with decreased atherosclerotic risk. The mechanisms by which phytosterols impart their effects, however, are incompletely characterized. The objective of the present study is to determine if pancreatic cholesterol esterase (PCE; EC 3.1.1.13), the enzyme primarily responsible for cholesterol ester hydrolysis in the digestive tract, is capable of hydrolyzing various phytosterol esters and to compare the rates of sterol ester hydrolysis in vitro. We found that PCE hydrolyzes palmitate, oleate and stearate esters of cholesterol, stigmasterol, stigmastanol and …
