Feeding Corn Milling Co-Products To Forage Fed Cattle, 1st Edition, Aaron Stalker, Rick Rasby, Galen E. Erickson, Crystal Buckner, Terry J. Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Introduction

Beef calves from weaning until they enter feedlots, developing heifers, and beef cows are fed primarily forage diets. Especially in the winter, forages are low in protein and phosphorus and need to be supplemented. Corn milling co-products are excellent sources of both protein and phosphorus and fi t nicely into winter supplementation programs. Corn milling co-products are also an excellent source of energy and are particularly well suited to forage based diets.

Two primary types of milling processes currently exist, resulting in quite diff erent feed products. The dry milling process produces distillers grains plus solubles (DGS), and the …

Interaction Between Roughages And Corn Milling Byproducts In Finishing Cattle Diets, Joshua R. Benton

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

During ethanol production, starch is the primary nutrient fermented and the remaining byproducts are excellent sources of fiber and protein. In addition, inclusion of byproducts in finishing diets may reduce the incidence of acidosis. As a result, roughage level and quality could potentially be reduced in finishing diets containing byproducts. Three experiments were conducted to examine the effects of roughage and wet corn gluten feed (WCGF) in finishing cattle diets containing corn distillers grains plus solubles. Cattle fed finishing diets containing wet distillers grains plus solubles (WDGS) with no roughage had decreased DMI and ADG compared to cattle fed roughage. …

The Relationship Between Breastfeeding And Child Care For Working Mothers In The United States, Patricia Wonch Hill

Department of Sociology: Dissertations, Theses, and Student Research

Whether or not child care provider characteristics and factors related to the care giving environment impact breastfeeding duration for working mothers has not been systematically studied. In this dissertation, I use Ecological Health Promotion Theory to explore the relationship between child care and breastfeeding through three different analyses. First, I interviewed nine child care providers to assess their knowledge, attitudes and beliefs about infant feeding and whether they vary on these factors across individuals and child care licensing types. Second, I conducted a small mail survey of 93 licensed child care providers in order to create a scale measuring attitudes …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

This study was conducted to evaluate the effect of pulsed electric field (PEF) treatment on anthocyanin extraction from red cabbage using water as a solvent. Mashed cabbage was placed in a batch treatment chamber and subjected to PEF (2.5 kV/cm electric field strength; 15 μs pulse width and 50 pulses, specific energy 15.63 J/g). Extracted anthocyanin concentrations (16 to 889 μg/mL) were determined using HPLC. Heat and light stabilities of the control and PEF-treated samples, having approximately the same initial concentrations, were studied. PEF treatments enhanced total anthocyanin extraction in water from red cabbage by 2.15 times with a higher …

Detection Methods For The Genus Lysobacter And The Species Lysobacter Enzymogenes, Hu Yin

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

Strains of Lysobacter enzymogenes, a bacterial species with biocontrol activity, have been detected via 16S rDNA sequences in soil in different parts of the world. In most instances, however, their occurrence could not be confirmed by isolation, presumably because the species occurred in low numbers relative to faster-growing species of Bacillus or Pseudomonas. In this study, we developed DNA-based detection and enrichment culturing methods for Lysobacter spp. and L. enzymogenes specifically. In the DNA-based method, a region of 16S rDNA conserved among Lysobacter spp. (L4: GAG CCG ACG TCG GAT TAG CTA GTT), was used as the forward …

Selection For Increased Starvation Resistance Using Drosophila Melanogaster: Investigating Physiological And Life History Trait Responses To Starvation And Dietary Supplementation In The Context Of An Obese Phenotype, Tiffany Elisse Schwasinger-Schmidt

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

Artificial selection for starvation resistance provided insight into the relationships between evolved physiological and life history trait responses following exposure to biologically induced stress. Investigations of alterations to body composition, metabolic rate, movement, and life history traits including development time, female egg production, and longevity in response to brief periods of starvation were conducted on genetically based starvation-resistant and control lines of Drosophila melanogaster. Analysis of the starvation-resistant lines indicated increased energy storage with increased triglyceride deposition and conversion of carbohydrates to lipid, as identified by respiratory quotient values. Correlations between reductions in metabolic rates and movement in the starvation-resistant …

The Effect Of Natural Antimicrobial Ingredients On The Quality Of Roast Beef And Oven Roasted Turkey, Ace F. Vandewalle

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

This research evaluates the use of a buffered vinegar and lemon juice concentrate (LV) solution on the quality of restructured beef and turkey rolls. Two studies were conducted to evaluate processing and ingredient concentration. Beef and turkey rolls were formulated with minimal ingredients. 1.5% sea salt, 0.5% turbinado sugar, with LV or no LV. Study one evaluated length of mixing time (2.5, 5, 10, 15, 20 minutes) on quality and sensory attributes with 2.5% LV or 0% LV (C). Study two was divided into four treatments, 0% (C), 1.5%, 2.5%, and 3.5% LV, used to evaluate the effects of three …

The Effects Of High Pressure Processing On Peanut Sauce Inoculated With Salmonella, Tara K. Stiles

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

Recent Salmonella outbreaks have prompted the need for new processing options for peanut products. Traditional heating kill-steps have shown to be ineffective in lipid-rich matrices such as peanut products. High pressure processing is one such option for peanut sauce because it has a high water activity, which has proved to be a large contributing factor in microbial lethality due to high pressure processing. Four different formulations of peanut sauce were inoculated with a five strain Salmonella cocktail and high pressure processed. Results indicate that increasing pressure or increasing hold time increases log₁₀ reductions. The Weibull model was fitted to …

Regulation Of Atp Binding Cassette Transporter A1 And G1 Expression By Fatty Acids, Chai Siah Ku

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

High density lipoprotein (HDL) is an atheroprotective element which is critical in the reverse cholesterol transport (RCT) pathway to eliminate excess cholesterol from the periphery of the body. A low plasma HDL cholesterol levels indicate a higher risk of getting cardiovascular diseases (CVD). Formation and metabolism of HDL largely rely on ATP binding cassette transporter A1 (ABCA1) and G1 (ABCG1) that are transporters to facilitate the efflux of cellular cholesterol to outside of cells. ABCA1 in the liver and small intestine is the major contributing factor for HDL formation. On the other hand, ABCA1 and ABCG1 present in macrophages contribute …

Department of Nutrition and Health Sciences: Faculty Publications

This study tested the hypothesis that a culturally developed omega-3 (n-3) fatty acid food frequency questionnaire (FFQ) could be an accurate instrument to capture n-3 fatty acid food intakes of first-generation Midwestern Latinas. The goal of the study was to assess validity and test-retest reliability of an FFQ to estimate total n-3 fatty acid (total n-3), α-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) intakes. An n-3 FFQ was developed and pilot tested. Two FFQs and 3 nonconsecutive 24-hour recalls were collected from 162 participants. Pearson correlation and paired t test were used to test the hypothesis. Correlation …

A Pilot Study To Determine The Effectiveness Of Probiotic Use In Elderly Patients With Antibiotic-Associated Diarrhea, Jenna L. Peate

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

Long-term care settings have the majority of their patients on multiple antibiotics, and outbreaks of antibiotic-associated diarrhea and Clostridium difficile are common. Probiotics have been used with these patients to reduce these side effects. Probiotics can re-establish the composition of intestinal microflora, enhance immune response, and clear pathogens from the host which may reduce the symptoms of antibiotic-associated diarrhea. Therefore, the goal of this study was to conduct a retrospective study of the effectiveness of using probiotic in elderly patients in a long-term care facility in a Midwestern city who suffered from antibiotic-associated diarrhea. The probiotic, CulturelleTM had been administered …

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

A CURRENT EXAMINATION OF DIETARY INTAKES OF FIBER, CALCIUM, IRON, AND ZINC AND THEIR RELATIONSHIP TO BLOOD LEAD LEVELS IN U.S. CHILDREN AGED 1-5 YEARS Stephanie Ann Melchert, M.S. University of Nebraska, 2010 Adviser: Kaye Stanek Krogstrand The effect of lead on the health and well-being of those exposed has been well documented and many efforts have been made to reduce exposure of lead to the United States population. Despite these efforts, many studies have documented cognitive impairments and behavioral problems in children with even low levels of lead in their blood. Previous studies have suggested that a proper diet …

Environment And Hybrid Influences On Food-Grade Sorghum Grain Yield And Hardness, Joni K. Griess, Stephen C. Mason, David S. Jackson, Tomie D. Galusha, Muhammad Yaseen, Jeffrey F. Pedersen

Department of Food Science and Technology: Faculty Publications

Few studies have examined grain quality of food-grade sorghum hybrids. The objective of this study was to determine the effects of environment and hybrid on grain quality of commercially available food-grade sorghums. A randomized complete block experiment with three replications was planted in 12 environments, which included the 2004 and 2005 growing seasons and irrigated and dryland water regimes in eastern, central, and west central Nebraska and a dryland low-N environment in eastern Nebraska. Environment accounted for 5 to 140 times greater variation in measured parameters than hybrid, and the hybrid × environment interaction accounted for less than 2% of …

Physiological Studies On Candida Albicans, Swetha Tati

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

Candida albicans is a common opportunistic, dimorphic human fungal pathogen. One of its virulence factors is the morphological switch between yeasts and hyphal or pseudohyphal forms, which can invade tissues and cause damage. Our studies focus on factors regulating pseudohyphae and epigenetic modifications of C. albicans. Regulating factors of pseudohyphae are aromatic alcohols and high phosphate. At low concentrations, exogenous aromatic alcohols induced pseudohyphae, as did high phosphate. For addressing the pathways involved in inducing pseudohyphae by aromatic alcohols or high phosphate, we used mutants defective in cAMP dependent PKA pathway (efg1/efg1), MAP kinase pathway (cph1/cph1), or both (cph1/cph1/efg1/efg1). …

Holocarboxylase Synthetase-Dependent Biotinylation Of Histone H4, Luisa F. Rios Avila

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

Holocarboxylase synthetase (HCS) catalyzes the binding of biotin to lysine (K) residues in histones H3 and H4. Histone biotinylation marks play important roles in the repression of genes and retrotransposons. Preliminary studies suggested that K16 in histone H4 is a target for biotinylation by HCS. Here we demonstrated that H4K16bio is overrepresented in repeat regions {pericentromeric alpha satellite repeats; long terminal repeats (LTR)} compared with euchromatin promoters. H4K16bio was also enriched in the repressed interleukin-2 gene promoter. The enrichment at LTR22 and promoter 1 of the sodium-dependent multivitamin transporter (SMVT) depended on biotin supply; and was significantly lower in fibroblasts …

A Parasitological Paradox: Why Is Ascarid Infection So Rare In The Prehistoric Americas?, Daniela Leles, Karl Reinhard, Martín Horacio Fugassa, Luis Fernando Ferreira, Alena M. Iñiguez, Adauto Araujo

Karl Reinhard Publications

Ascaris lumbricoides (giant roundworm) and Trichuris trichiura (whipworm) are the most common intestinal parasites found in humans worldwide today and they almost always co-occur. However, we find two distinct patterns in archae­ological material. In historical North American and Old World contexts, the association of A. lumbricoides and T. trich­iura is similar to the modern epidemiological picture. In contrast, the co-occurrence of A. lumbricoides and T. trichiura eggs in prehistoric South America is rare. For prehistoric contexts, T. trichiura is the most common parasite found in ar­chaeological material. Recently molecular biology techniques pointed to a subdiagnosis of roundworm infection in pre- …

Identification Of Markers Associated With Sow Lifetime Productivity For Whole Genomic Selection, Daniel Ciobanu

Department of Animal Science: Faculty Publications

Sows are more productive today than ever before. However, concurrent with increased prolificacy, high sow death losses and replacement rates are serious economic and welfare issues facing producers. Reproductive failure is the most frequent reason for culling sows. Length of productive life is moderately heritable and has high variance; thus, substantial genetic variation is expected to exist in most populations. Genetic improvement in the swine industry occurs from selection in nucleus herds and is then transmitted through the breeding pyramid in the multiplication process. Thus, it is critical to identify selection methods that can be applied in nucleus herds that …

A Functional Calcium-Transporting Atpase Encoded By Chlorella Viruses, Maria Cristina Bonza, Holger Martin, Ming Kang, Gentry L. Lewis, Timo Greiner, Sonia Giacometti, James L. Van Etten, Maria Ida De Michelis, Gerhard Thiel, Anna Moroni

James Van Etten Publications

Calcium-transporting ATPases (Ca²⁺ pumps) are major players in maintaining calcium homeostasis in the cell and have been detected in all cellular organisms. Here, we report the identification of two putative Ca²⁺ pumps, M535L and C785L, encoded by chlorella viruses MT325 and AR158, respectively, and the functional characterization of M535L. Phylogenetic and sequence analyses place the viral proteins in group IIB of P-type ATPases even though they lack a typical feature of this class, a calmodulin-binding domain. A Ca²⁺ pump gene is present in 45 of 47 viruses tested and is transcribed during virus infection. Complementation analysis of …

Comparing Observations Of Age At First Reproduction In Western Gray Whales To Estimates Of Age At Sexual Maturity In Eastern Gray Whales, Amanda L. Bradford, David W. Weller, Aimée R. Lang, Grigory A. Tsidulko, Alexander M. Burdin, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Age at first reproduction (AFR) is a basic component of age-structured whale assessment models, but direct estimates of this parameter do not exist for either the abundant eastern or critically endangered western population of gray whales (Eschrichtius robustus). Instead, assessments of both populations have utilized either of two recognized estimates of eastern gray whale age at sexual maturity (ASM) that are adjusted by a year to account for fetal gestation. These ASM estimates are: 1) 9 years median, 6-12 years range, and 2) 6 years median, 5-9 years range, but there are biases and discrepancies associated with these …

Why Don’T Rats And Mice Vomit? A Behavioral And Anatomical Investigation, C. C. Horn, National Wildlife Res. Ctr, G.R. Gathright, B. Yates, P.L. Andrews

United States Department of Agriculture Wildlife Services: Staff Publications

Laboratory rats and mice are known to lack a vomiting response and the dimensions of the abdominal esophagus might be an important constraint (Andrews, 1995, Physiol. Zool.). However, a broad evaluation of Rodentia is lacking. Here we determined the behavioral responses and esophageal and diaphragm anatomy from 4 of the 5 Suborders.Weused prototypical emetic agents, apomorphine (s.c.), veratrine (s.c.), and copper sulfate (i.g.), which are thought to produce emesis by action on the area postrema, nodose ganglia, and vagal afferent fibers, respectively. None of the rodents, including nutria (Myocastor coypus), beavers (Castor canadensis), mountain beavers …

Validation Of Nutrition Standardized Language—Next Steps, Paula Ritter-Gooder, Nancy M. Lewis

Department of Nutrition and Health Sciences: Faculty Publications

To provide a model for quality care and outcomes management, the Nutrition Care Process (NCP) and standardized language were introduced in 2003 by the American Dietetic Association (ADA). The standardized language, published in the International Dietetics & Nutrition Terminology (IDNT) Reference Manual: Standardized Language for the Nutrition Care Process, is designed to facilitate communication, improve care, and close the gap in health care quality. When registered dietitians (RDs) are oriented to a nutrition care process, improvement in their documentation of nutrition care occurs. Since the introduction of the NCP and standardized language, RDs and dietetic technicians, registered (DTRs), have …
