Pharmacokinetic Evaluation Of The Blood: Tissue Relationship In Poultry: Screening For Antibiotic Residues In Chicken Muscle, Ixchel Reyes Herrera

Graduate Theses and Dissertations

During their life, humans are exposed to numerous substances that are naturally present in the environment or that are the result of man made processes, including heavy metals, persistent organic pollutants, pesticides and veterinary drugs. Some of these substances can leave residues in food products and possibly expose consumers to their potential toxic effects. To address these problems extensive regulatory efforts are devoted to prevent, detect and control these substances from reaching the food supply. However, given the vast diversity of food products that requires monitoring and the immense diversity of potential chemical contaminants, the need for an efficient and …

Reproductive Life History Of Fundulus Jenkensi And Comparative Development Of Five Sympatric Fundulid Species, Eric Thomas Lang

Master's Theses

Fundulus jenkinsi is recognized federally and within the state of Mississippi as a Species of Concern. Little is known about the life history of this coastal killifish, but a detailed reproductive histology study of F. jenkinsi and a diagnostic key of the early life stages of select members of Fundulidae can provide the foundation needed to accurately identify it and quantify reproductive parameters in this rare species in need of conservation. Monthly gonadosomatic index (GSI) of male and female F. jenkinsi were documented, and spawning phases and oocyte stages were examined using reproductive histology. In addition, various stages of …

Ecology And Management Of A High Elevation Southern Range Greater Sage-Grouse Population: Vegetation Manipulation, Early Chick Survival, And Hunter Motivations, Michael R. Guttery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My research provided new information concerning the management, ecology, and conservation of greater sage-grouse (Centrocercus urophasianus). I report the results of an experiment using strategic intensive sheep grazing to enhance the quality of greater sage-grouse brood-rearing habitat. Although forb cover, an important component of brood-rearing habitat, responded positively to the grazing treatment, the response of other habitat variables was suppressed because the plots were not protected from domestic and wild herbivores during the years following the treatments. Measurements taken in grazing exclosures confirmed that herbivory by both large and small animals had significant impacts on vegetation. However, despite …

Effects Of Dietary Choline, Folic Acid And Vitamin B12 On Laying Hen Performance, Egg Components And Egg Phospholipid Composition, Pradeep Krishnan Rajalekshmy

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

In trial 1, a corn-soy basal diet was formulated with three levels of supplemental choline (0, 500 and 1000 ppm) and three levels of supplemental folic acid (0, 2 and 4 ppm) in a 3 x 3 factorial arrangement. Folic acid at 2 ppm increased egg production (p ≤ 0.04). Egg wt was higher at 500 ppm of choline (p ≤ 0.06) and 0 ppm (p ≤ 0.01) of folic acid supplementation. There were choline by folic acid interaction effects on feed intake (p ≤ 0.001), albumen wt (p ≤ 0.005) and yolk wt ( …

The Use Of Genetics For The Management Of A Recovering Population: Temporal Assessment Of Migratory Peregrine Falcons In North America, Jeff A. Johnson, Sandra L. Talbot, Kurt K. Burnham, George K. Sage, Joseph W. Brown, Tom L. Maechtle, William S. Seegar, Michael A. Yates, Bud Anderson, David P. Mindell

Raptor Research Center Publications and Presentations

Background: Our ability to monitor populations or species that were once threatened or endangered and in the process of recovery is enhanced by using genetic methods to assess overall population stability and size over time. This can be accomplished most directly by obtaining genetic measures from temporally-spaced samples that reflect the overall stability of the population as given by changes in genetic diversity levels (allelic richness and heterozygosity), degree of population differentiation (F_ST and D_EST), and effective population size (N_e). The primary goal of any recovery effort is to produce a longterm self-sustaining …

Diatoms As Indicators Of Water-Level Change In Freshwater Lakes, Julie A. Wolin, Jeffrey R. Stone

Biological, Geological, and Environmental Faculty Publications

Water-level changes result from a variety of geological, biological, and/or climatic processes. Many of these changes occur over long periods; others may be rapid or result from catastrophic events. In aquatic environments, diatoms are highly sensitive indicator organisms and their microfossils, deposited in lake sediments, can be used to infer environmental changes (Smol, 2008). Unambiguous diatom signals can be reconstructed from lakes isolated from marine or brackish waters (e.g. Fritz et al., this volume; Horton & Sawai, this volume). However, in freshwater systems lake-level changes are often recorded as increases in planktonic (free-floating) diatoms – although as discussed below, interpretation …

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2008, Jennie Popp, Nathan Kemper, Wayne Miller, Katherine Mcgraw, Kyle Karr

AAES Research Reports and Research Bulletins

This report is the fifth in a series of reports examining agriculture’s economic contribution to the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis (BEA), USDA Economics Research Service (ERS), USDA National Agricultural Statistics Service (NASS), and Minnesota IMPLAN Group, Inc. (MIG), the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2008. Gross Domestic Product (GDP) by State information for Arkansas was compared with those of other states in the southeast U.S. to give a measure of the relative importance of agriculture in Arkansas.2 The total economic contribution …

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 …

Tips For New Horse Owners, Kathleen P. Anderson, Cushman

Department of Animal Science: Faculty Publications

Pleasure horses for personal and recreational use representthe largest category of horse ownership in the United States, with about 2 million people owning such horses. Whether a person already owns a horse or is considering the initial purchase of a horse, this NebGuide will help answer many questions asked by new horse owners.

Horses can be kept at a person’s own place or boarded at a commercial stable. Keeping a horse on a person’s acreage provides more management control, saves time and expenses, and can reduce the risk of injuries and disease. Most importantly, it allows fuller enjoyment and greater …

Match–Mismatch Regulation For Bluegill And Yellow Perch Larvae And Their Prey In Sandhill Lakes, Jeffrey C. Jolley, David W. Willis, Richard S. Holland

Nebraska Game and Parks Commission: Staff Research Publications

Food availability may regulate fish recruitment, both directly and indirectly. The availability of zooplankton, especially to newly hatched larvae, is thought to be crucial to their early growth and survival. We examined stomach contents of larval bluegill Lepomis macrochirus and yellow perch Perca flavescens in Pelican Lake and Cameron Lake, Nebraska, in 2004 and 2005. We also determined zooplankton availability and calculated prey selection using Chesson’s a. In addition, we investigated potential match–mismatch regulation of recruitment from 2004 to 2008. Bluegill positively selected copepod nauplii and Bosmina spp., and yellow perch often selected copepods. Abundant zooplankton populations were available for …

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 …

Multi-Scale Perspectives On Paddlefish Populations: Implications For Species Conservation And Management, Brenda M. Pracheil

School of Natural Resources: Dissertations, Theses, and Student Research

The Order of fishes containing paddlefish and sturgeon has been named the most endangered group of organisms on the planet by the International Union of Conservation of Nature (IUCN). Population trajectories of paddlefish, whose native range is entirely encompassed within the United States of America, are currently unknown, although the IUCN has considered them to have a high extinction risk in the wild. The declaration of the vulnerability of paddlefish to extinction, coupled with the global plight of other sturgeon species create urgency to establish population and species-level population trajectories. Moreover, this declaration creates a great need for swift management …

Genetic Introgression And The Survival Of Florida Panther Kittens, Jeffrey A. Hostetler, David P. Onorato, James D. Nichols, Warren E. Johnson, Melody E. Roelke, Stephen J. O'Brien, Deborah Jansen, Madan K. Oli

Biology Faculty Articles

Estimates of survival for the young of a species are critical for population models. These models can often be improved by determining the effects of management actions and population abundance on this demographic parameter. We used multiple sources of data collected during 1982–2008 and a live-recapture dead-recovery modeling framework to estimate and model survival of Florida panther (Puma concolor coryi) kittens (age 0–1 year). Overall, annual survival of Florida panther kittens was 0.323 ± 0.071 (SE), which was lower than estimates used in previous population models. In 1995, female pumas from Texas (P. c. stanleyana) were …

The Braincase Of Youngina Capensis (Reptilia, Diapsida): New Insights From High-Resolution Ct Scanning Of The Holotype, Nicholas M. Gardner, Casey M. Holliday, F. Robin O’Keefe

Biological Sciences Faculty Research

Detailed descriptions of braincase anatomy in early diapsid reptiles have been historically rare given the difficulty of accessing this deep portion of the skull, because of poor preservation of the fossils or the inability to remove the surrounding skull roof. Previous descriptions of the braincase of Youngina capensis, a derived stem-diapsid reptile from the Late Permian (250 MYA) of South Africa, have relied on only partially preserved fossils. High resolution X-ray computed tomography (HRXCT) scanning, a new advance in biomedical sciences, has allowed us to examine the reasonably complete braincase of the holotype specimen of Youngina capensis for the …
