Song Recognition And Heterospecific Associations Between 2 Fairy-Wren Species (Maluridae), Allison E. Johnson, Christina Masco, Stephen Pruett-Jones

School of Biological Sciences: Faculty Publications

Although heterospecific associations beneficial to one or both species involved (e.g. commensalisms or mutualisms) are common, it is generally assumed that interactions between species are transient and not particular to individuals. However, long-term interactions between individuals of different species do occur. In such heterospecific social groups, discrimination between heterospecific individuals may be beneficial, allowing individuals to direct beneficial or aggressive behaviors towards appropriate targets. Here, we describe heterospecific groups composed of splendid and variegated fairy-wrens (Malurus splendens and M. lamberti) and provide the first experimental evidence that recognition of heterospecific group members occurs across species. In these species, …

The Effect Of Magnetic Water On Feed Conversion Ratio, Body Weight Gain, Feed Intake And Livability Of Male Broiler Chickens, Kenia Mitre

Poultry Science Undergraduate Honors Theses

Passing water through a magnetic field has been shown to have positive effects in agricultural activities such as crops, cattle and poultry production (Ali, Samaneh and Kavakebian, 2014). Several experiments performed in Middle Eastern countries have evaluated the effect of magnetizing drinking water on poultry performance, but results are inconsistent. The current project was conducted to evaluate the effect of magnetizing the drinking water on key aspects of poultry production such as Feed Conversion Ratio, Body Weight Gain, Feed Intake and Livability. Four hundred and forty-nine male Cobb-500 chicks were randomly placed in 6 replicate pens for each of 3 …

Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, Sarah-Beth Delay

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Foreign Direct Investment (FDI) has the potential to increase economic activity and improve GDP growth in low-income countries, but can hinder economic development (quality of life improvements) if not sustainable and holistic in manner. Africa serves as a host to many cases of FDI focused on economic growth, but not necessarily improving the quality of life for its citizens. FDI has spread throughout the African continent, where many countries are well endowed with natural resources, like minerals and coal. These economies have experienced rapid GDP growth with few benefits reaching citizens of the host country. Mozambique is a low-income country …

Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans

Wildlife Damage Management Technical Series

Abundant gull (Figure 1) populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to …

Microbiome Of Commercial Broilers Through Evisceration And Immersion Chilling, John A. Handley

Graduate Theses and Dissertations

The United States poultry industry generated 38.6 billion pounds (17,500 metric ton) of meat in 2014 which averaged to 121 pounds (55 kg) per individual of the U.S that same year. Of that meat generated by the poultry industry, an estimated 1 million cases of Salmonellosis will occur. Out of the 1 million cases approximately 40, 000 to 50,000 will be confirmed cases by the CDC. Recently, the USDA has requested changes in the inspection process and are currently allowing processors more freedom to utilize innovation to drive the increase in safer and more desirable foods. The new standards set …

Evaluation Of The Efficacy Of A Candidate Turkey Dermatitis/Cellulitis Oil Emulsion Vaccine On Immune Response, Morbidity, And Mortality Under Laboratory And Commercial Conditions, Brittany Danielle Graham

Graduate Theses and Dissertations

Alpha-toxigenic Clostridium septicum (CS), the cause of turkey cellulitis, results in devastating mortality with high costs for the industry. Various vaccinations have been evaluated to prevent this disease with moderate success. Ability of a CS bacterin-toxoid, in conjunction with adjuvants such as aluminum hydroxide, mannoslyated chitosan, or a water-in-oil Seppic Montanide 71 R VG adjuvant (OE) to induce immunity was evaluated in a 7-week study (Experiment 1). Poults (20/group) were vaccinated day-of-hatch, boosted at 5 weeks-of-age and compared to unvaccinated controls. Antibody titers were determined by ELISA for all experiments. In experiment 1, initial vaccination with OE resulted in significantly …

Evaluation Of The Effects Of Formaldehyde On Growth Parameters Of Broiler Chicks, Paula Johnson

Graduate Theses and Dissertations

Formaldehyde has been used as a disinfectant in poultry hatching cabinets to aid in controlling key pathogenic organisms, such as Salmonella and Escherichia coli (E.coli). There is some evidence that prolonged exposure of chicks to formaldehyde can reduce tracheal ciliary function and thus reasons to believe that exposure to formaldehyde, in the absence of pathogen challenge, may reduce chick vitality. It has been found that elevated temperatures during incubation may adversely affect body weights of broiler chicks, as well as post-hatch environmental heat stress on performance in poultry. Post-hatch environmental heat stress has been shown to impact performance in poultry. …

Effects Of Dimethyl Sulfoxide And Glycerol Based Vitrification Protocols On Zona Pellucida Hardening In Mature Bovine Oocytes, Kaci Denise Rogers

LSU Master's Theses

Zona pellucida hardening is a natural process that occurs after oocyte fertilization to prevent polyspermic fertilization and to protect embryonic development. Pre-fertilization hardening of the zona pellucida however, decreases fertilization rates. Cryoprotectants have also been shown to negatively affect fertilization rates, one possible mechanism of which being through zona hardening. This experiment was conducted to determine the effect of different cryoprotectants on hardening of the zona pellucida using fresh mature bovine oocytes and vitrified mature bovine oocytes. Oocytes were post-slaughter from mixed breed cows. After collection, oocytes were randomly assigned to three cryoprotectant treatment groups: dimethyl sulfoxide (DMSO), glycerol or …

Transcriptional Profiling Of Liver In Riboflavin-Deficient Chicken Embryos Explains Impaired Lipid Utilization, Energy Depletion, Massive Hemorrhaging, And Delayed Feathering, Larry A. Cogburn, Danielle N. Smarsh, Xiaofei Wang, Nares Trakooljul, Wilfrid Carré, Harold B. White Iii

Biology Faculty Research

Background

A strain of Leghorn chickens (rd/rd), unable to produce a functional riboflavin-binding protein, lays riboflavin-deficient eggs, in which all embryos suddenly die at mid-incubation (days 13-15). This malady, caused by riboflavin deficiency, leads to excessive lipid accumulation in liver, impaired β-oxidation of lipid, and severe hypoglycemia prior to death. We have used high-density chicken microarrays for time-course transcriptional scans of liver in chicken embryos between days 9-15 during this riboflavin-deficiency-induced metabolic catastrophe. For comparison, half of rd/rd embryos (n = 16) were rescued from this calamity by injection of riboflavin just prior to incubation of fertile …

A Comparative Analysis Of Microbial Profile Of Guinea Fowl And Chicken Using Metagenomic Approach, Sarayu Bhogoju, Samuel N. Nahashon, Xiaofei Wang, Carl E. Darris, Agnes Kilonzo-Nthenge

Agricultural and Environmental Sciences Faculty Research

Probiotics are live microbial feed supplements that promote growth and health to the host by minimizing non-essential and pathogenic microorganisms in the host’s gastrointestinal tract (GIT). The campaign to minimize excessive use of antibiotics in poultry production has necessitated development of probiotics with broad application in multiple poultry species. Design of such probiotics requires understanding of the diversity or similarity in microbial profiles among avian species of economic importance. Therefore, the objective of this research was to establish and compare the microbial profiles of the GIT of Guinea fowl and chicken and to establish the microbial diversity or similarity between …

Winter Field Report, December 2017 To February 2018, W. Ross Silcock

Nebraska Bird Review

This was not a spectacular fall by most measures, but, as usual, there was much to chew on. Continuing the trend seen in recent falls, lingering has become the norm; this phenomenon is across the board, involving, for example, Baird’s Sandpiper, Greater Yellowlegs, Mourning Dove, American White Pelican, Barn Owl, Lesser Goldfinch, several native sparrow species, Palm and Orange-crowned Warblers, and even rearof- the-order Dickcissel. Apparent range expansion is occurring with Red-shouldered Hawk and Barred Owl, the former northward and the latter westward. A couple of taxonomic notes relate to the subspecies Buteo jamaicensis abieticola of Red-tailed Hawk and subspecies …

2017-2018 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were held during the 2017-18 Christmas Bird Count season, which is one more than has ever been done in the past. Although the Crawford count was not done this season, the new Lower Platte River count, centered at the junction of Platteview Road and 204th St. south of Gretna, was added. A total 236 observers took part in at least one count, 26 did two counts, four did three counts, five did four counts and four persons did six counts. However, special recognition goes to Gary Roberts, who did eight counts this season. I am not aware of …

Ms Environmental Biology Capstone Project, Taylor Readyhough

Regis University Student Publications (comprehensive collection)

Life in a zoo brings a score of stressors into the lives of captive animals, including artificial light, crowds of visitors, and increased noise levels. Stress especially impacts captive birds, and continued exposure to these stressors can negatively affect birds’ reproductive success and overall well-being. Staff at the Denver Zoo noticed increased aggression between a male and female pair of great Indian hornbills during the winter of 2016. This behavioral shift coincided with Zoo Lights, a holiday event that results in the hornbills’ exhibit remaining open to the public for approximately four extra hours through the entire month of December. …

Integrating Morphology And Kinematics In The Scaling Of Hummingbird Hovering Metabolic Rate And Efficiency, Derrick J. E. Groom, M. Cecilia B. Toledo, Donald R. Powers, Bret W. Tobalske, Kenneth C. Welch Jr.

Faculty Publications - Department of Biological & Molecular Science

Wing kinematics and morphology are influential upon the aerodynamics of flight. However, there is a lack of studies linking these variables to metabolic costs, particularly in the context of morphological adaptation to body size. Furthermore, the conversion efficiency from chemical energy into movement by the muscles (mechanochemical efficiency) scales with mass in terrestrial quadrupeds, but this scaling relationship has not been demonstrated within flying vertebrates. Positive scaling of efficiency with body size may reduce the metabolic costs of flight for relatively larger species. Here, we assembled a dataset of morphological, kinematic, and metabolic data on hovering hummingbirds to explore the …

Ainsworth Fall Field Days, Janis Paseka

Nebraska Bird Review

The 2018 NOU Fall Field Days took place in and around Ainsworth on Sep. 14 – 16, with 48 in attendance. It was a hot and windy weekend, but 137 species were located. Two Sandhill Cranes in the Niobrara River at the Carns Bridge attracted birders, especially since the two cooperatively moved from one side of the river to the other, allowing county listers to count them in both. The bird of the weekend, however, was the Red-naped Sapsucker at Plum Creek Valley WMA. It was a county bird for everyone, a state bird for many and a life bird …

Effect Of Exogenous Enzymes On Apparent Metabolizable Energy Value Of Barley In Swine And Broiler Chickens, Brian L. Bryson

Theses and Dissertations--Animal and Food Sciences

The objective of this thesis was to evaluate the effect of exogenous enzyme supplementation, phytase and xylanase-glucanase, on AME value of barley in poultry and swine. In the first study, 280 broilers were assigned 1 of 8 treatments. Barley inclusion in the diet resulted in decreased (P < 0.05) performance. There was a treatment × phytase × xylanase-glucanase interaction for dry matter retention with birds fed the corn-SBM-barley diet supplemented with phytase and xylanase-glucanase having higher (P < 0.05) DM retention compared to birds fed corn-SBM-based diet with only xylanase-glucanase supplementation. AME and AMEn of corn-SBM-based diets were greater (P < 0.05) than the corn-SBM-barley-based diets. Energy metabolizability and AMEn of barley significantly increased with xylanase-glucanase supplementation. In the second study, 24 pigs (12 pigs/phase) were assigned to 1 of 4 treatments with xylanase-glucanase and phytase. After a 7-d adaption period, urine and feces were quantitatively collected for 5 d. DE of the barley-based diet supplemented with xylanase-glucanase (3,578 kcal/kg) and phytase and xylanase-glucanase in combination (3,617 kcal/kg) were significantly different. Compared to control diets, exogenous enzymes either significantly improved or had a tendency to improve AME and AMEn value of barley in broilers, but not in growing pigs.

The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton

Theses and Dissertations--Psychology

Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Hunter Harvest Effect On The Breeding Bird Population Of Northern Pintail Anas Acuta In North America, Matthew Wang

Journal of Earth and Life Science

Hunter harvest and the effects that it can have on population dynamics is a relationship used by wildlife professionals when making management decisions. Hunter harvest can be compensatory or additive on wildlife populations and instances where hunter harvest has been a key role in a population decline, and sometimes demise, is an occurrence studied in wildlife management. Waterfowl numbers in North America have increased 17% since 1960, but during that same time frame the Northern Pintail population has decreased 40%. Hunter harvest data has been recorded by the U.S. Fish and Wildlife Service since 1961, while they have simultaneously been …

Analysing Intonation Of The Pied Butcherbird, Jean-Michel Maujean

Theses : Honours

Native to Australia, the Pied Butcherbird has been extensively studied and transcribed by previous composers, notably including Olivier Messiaen. This may be due to richness and diversity in each bird’s repertoire, along with parallels drawn from Western Tonality. Hollis Taylor has conducted extensive study in this field, notably with an analysis of a transcription made by Messiaen, that was incorporated in his piece Éclairs sur l'au- delà (1988-91). Coupled with the original field recording, Taylor’s analysis and Messiaen’s score, this study will reanalyse the original recording from which Messiaen made his transcription.

Fall Field Report, August - November 2017, W. Ross Silcock

Nebraska Bird Review

This fall season will be remembered as the fall with the mega-rarities. There were five, one of which, Pacific Wren, is a first Nebraska record. Based on occurrence dates, Hurricane Irma appears to have influenced the appearance of two of the megas, Black Vulture and Magnificent Frigatebird, neither of which provided opportunities for observers to view them, but both well-documented with photographs. There were an extraordinary TWO sightings of Harris’s Hawk, which together with the presence as of this writing (December 19) of one in northeast Kansas and a view of the species map in eBird strongly suggest a single …

Time Series Forecast Analysis In Wholesale Broiler Markets, Christopher R. Sims

Graduate Theses and Dissertations

In 2016 the chicken industry provided nearly 1.2 million jobs, 68 billion dollars in wages, 313 billion dollars in economic activity and 24 billion dollars in government revenue (John Dunham & Associates, Inc., 2016). Broiler production has changed dramatically from the early 90’s to the turn of the 21st century. Technological advancements, continuous improvements, production efficiencies and industry changes have made the industry the global market it is today. The poultry industry is an extremely volatile market with prices constantly fluctuating in response to input price volatility and demand and supply changes. These changes are often driven by world economic …
