Effect Of Feeding Regimen And Age On Lipid Metabolism In Broiler Breeder Hens And Progeny, Nirun Boonsinchai Jul 2015

Effect Of Feeding Regimen And Age On Lipid Metabolism In Broiler Breeder Hens And Progeny, Nirun Boonsinchai

Graduate Theses and Dissertations

Age of hens and feed allocation can affect egg yolk lipid compositions which in turn directly relate to chick quality. A series of experiments were conducted to determine the effects of age and feeding programs on lipid metabolism in breeder hens and progeny. In the first trial, the rate of yolk absorption and fatty acid profiles in the yolk were compared among 28, 35, and 49wk old hens. The results revealed that the rate of yolk absorption was higher, but the absolute amount of fatty acids absorbed was lower in young hens than in the old hens. The second trial …


Novel Biomarkers For Calcium And Phosphorus Metabolism In Breeder Hens And Broilers, Andrew Dick Magnuson Jul 2015

Novel Biomarkers For Calcium And Phosphorus Metabolism In Breeder Hens And Broilers, Andrew Dick Magnuson

Graduate Theses and Dissertations

Broiler breeder hens are subject to the dual expectation to not only maintain a high production of eggs for an extended time period, but to produce eggs which can support the life of chicks which will be used for either meat production or as parent stock. Egg fertility and hatchability are heavily influenced by the thickness of the egg shell, the mineral calcium carbonate shell of the egg necessary for protecting the embryo growing inside. Many factors affect egg shell quality including age of the hen, diet, environmental conditions, genetic strain, stress, disease, and nutrition. Laying hens will mobilize calcium …


Water Consumption Behavior In Broilers, David Harold Mccreery Jul 2015

Water Consumption Behavior In Broilers, David Harold Mccreery

Graduate Theses and Dissertations

A series of trials were conducted to analyze broiler water consumption behaviors under commercial conditions. The first trial was to quantify the number of broilers drinking at times of peak water demand. Birds were evaluated at time intervals of 5, 10, 15, 30, 45, and 60 minutes from the start of the light period to establish the percentage birds having consumed water by that point in time. Significant differences were found by bird age in the 5, 10, and 15 minute intervals, however there were no significant differences in the percentage of birds having consumed water in the 30, 45, …


The Ability Of Select Probiotics To Reduce Enteric Campylobacter Colonization In Broiler Chickens, Sandip Shrestha Jul 2015

The Ability Of Select Probiotics To Reduce Enteric Campylobacter Colonization In Broiler Chickens, Sandip Shrestha

Graduate Theses and Dissertations

Campylobacter is the leading cause of foodborne illness worldwide and is often associated with consumption and/or mishandling of contaminated poultry products. Probiotic use in poultry has been an effective strategy in reducing other enteric foodborne pathogens but not consistently for Campylobacter. As Campylobacter resides and utilizes intestinal mucin for growth, isolates selected on the basis of mucin utilization might be a strategy to screen for efficacious probiotic bacterium. In this study, bacterial isolates demonstrating increased growth rates in mucin, in vitro (trials 1 or 2), or isolates demonstrating a reduction of Campylobacter counts when co-incubated with mucin, in vitro (trials …


Meat Quality Of Broiler Breast Fillets With White Striping And Woody Breast Muscle Myopathies, Vishwesh Vijay Tijare Jul 2015

Meat Quality Of Broiler Breast Fillets With White Striping And Woody Breast Muscle Myopathies, Vishwesh Vijay Tijare

Graduate Theses and Dissertations

The global poultry industry has been faced with emerging broiler breast meat quality issues known as white striping and woody breast. Two experiments were conducted to evaluate effects of white striping and woody breast hardness on meat quality traits in broiler breast fillets. Birds were processed at 8 wk (Exp.1) and at 6 and 9 wk of age (Exp.2), whereas deboning was carried out at 4 and 2 h postmortem in Exp.1 and 2, respectively. Fillets were categorized as: normal for both white striping and woody breast (NORM); mild for white striping and woody breast (MILD); severe for white striping …

In Vitro And In Vivo Evaluation Of Infestation Deterrents Against Lice, Kyong-Sup Yoon, Jennifer K. Ketzis, Samuel W. Andrewes, Christopher S. Wu, Kris Honraet, Dorien Staljanssens, Bart Rossel, J Marshall Clark

SIUE Faculty Research, Scholarship, and Creative Activity

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated …


Oriole Consumption Of Grape Jelly, Gary Lingle Jun 2015

Oriole Consumption Of Grape Jelly, Gary Lingle

Nebraska Bird Review

It is well known that several species of orioles are attracted to grape (Vitis sp.) jelly. A few years ago I began “feeding” grape jelly to orioles in my yard in Buffalo County. Both Baltimore Orioles (Icterus galbula) and, to a lesser extent, Orchard Orioles (Icterus spurius) frequented my feeder upon their arrival in early May and fed daily until the red mulberries (Morus rubra) ripened and nesting had commenced prior to mid-June. At that time visitation to my feeder plummeted from a high of 1.5 birds per minute to 0 .1 birds …

Spring Field Report, March 2015 To May 2015, W. Ross Silcock

Nebraska Bird Review

This was a largely uneventful spring in terms of major events, as most species stayed within their ranges and movement timing parameters. There are always a few stochastic exceptions, but no clear pattern of, for example, early arrival dates was discernible. However, several interesting situations came to light, and there were a few rarities detected. A Couch’s Kingbird in Sarpy Co was well described but awaits a determination by the Nebraska Ornithologists' Union Records Committee as to whether the evidence is strong enough to add this species to the Official State Bird List. Other exciting finds were a wintering Brown …

Book Review [Of At Home And At Large In The Great Plains: Essays And Memories], Janis Paseka

Nebraska Bird Review

Nebraska birders may remember reading some of the 14 essays published in this book, since they appeared previously in Prairie Fire, the monthly Great Plains public policy newspaper. Topics of the short and engaging essays range from changing bird life to outstanding birding areas to conservation in the Great Plains. We read about sediment deposits, the “gifts of glaciers past,” which were left by retreating rivers of ice thousands of years ago and resulted in the creation of the prairie potholes so important now to our waterfowl and wading birds. One essay marvels at the variety of animal skeletons, including …


Mate Replacement And Alloparental Care In Ferruginous Hawk, Shubham Datta, Will M. Inselman, Jonathan A. Jenks, Kent Jensen, Christopher C. Swanson, Robert W. Klaver, Indrani Sasmal, Troy W. Grovenburg Jun 2015

Mate Replacement And Alloparental Care In Ferruginous Hawk, Shubham Datta, Will M. Inselman, Jonathan A. Jenks, Kent Jensen, Christopher C. Swanson, Robert W. Klaver, Indrani Sasmal, Troy W. Grovenburg

Natural Resource Management Faculty Publications

Alloparental care (i.e., care for unrelated offspring) has been documented in various avian species (Maxson 1978, Smith et al. 1996, Tella et al. 1997, Lislevand et al. 2001, Literak and Mraz 2011). A male replacement mate that encounters existing broods has options, which include alloparental care or infanticide. Infanticide may be beneficial in some species (Rohwer 1986, Kermott et al. 1990), but in long-lived avian species, like the ferruginous hawk (Buteo regalis) that do not renest within a season, infanticide might be detrimental. Adoption and rearing success likely provide direct evidence of competence of replacement mates as potential parents for …

Assessing Alabama Consumer Attitudes And Beliefs About Locally Or Regionally Produced Livestock And Products, Nii O. Tackie, Jannette R. Bartlett, Akua Adu-Gyamfi

Professional Agricultural Workers Journal

Abstract

Local and regional food production has gained increased interest of consumers in recent years. The study, therefore, focused on assessing consumer attitudes and beliefs on local or regional livestock products. Data were obtained from a convenience sample of 432 participants from South Central Alabama, and were analyzed using descriptive statistics, including chi-square tests. A majority of respondents thought using chemicals and additives in locally or regionally produced beef or goat meat was a serious hazard. Therefore, many were willing to pay more for meat certified as locally or regionally produced. Also, most agreed or strongly agreed with statements on …

Background

Guinea fowl (Numidia meleagris) production as an alternative source of meat and poultry has shown potential for economic viability. However, there has been little progress in characterizing the transcriptome of the guinea fowl. In this study RNA-sequencing and de novo transcriptome assembly of several Guinea fowl tissues (pancreas, hypothalamus, liver, bone marrow and bursa) which play key roles in regulating feed intake, satiety, and immune function was performed using Illumina’s Hi-Seq 2000.

Results

74 million sequences were generated and assembled into 96,492 contigs using the Trinity software suite. Over 39,000 of these transcripts were found to have …

Identification Of Species In Ground Meat Products Sold On The U.S. Commercial Market Using Dna-Based Methods, Dawn Kane

Food Science (MS) Theses

Mislabeling of ground meat products is a form of food fraud that can lead to economic deception and interfere with dietary restrictions related to allergens or religious beliefs. In various parts of the world, including Ireland, Mexico and Turkey, high levels of meat mislabeling have been reported between 2000-2015. However, there is currently a lack of information regarding this practice in the United States. Therefore, the objective of this study was to test a variety of ground meat products sold on the U.S. commercial market for the presence of potential mislabeling. Forty-eight ground meat samples were purchased from online and …

Arkansas Broiler Enterprise Assessment Tool… Ar B.E.A.T, Christopher R. Sims

Poultry Science Undergraduate Honors Theses

Poultry operations require numerous variable inputs for the operation to run. Due to this it is extremely difficult for poultry growers to estimate the financial capacity of the operation. The poultry industry had evolved over the years from back yard non-commercial hobby farms to vertically integrated contract farms. These changes have made it extremely important that poultry growers fully understand the revenue, expenses, and income associated with the operation. Under the contract system, it is difficult for poultry growers to have a full understanding of and expectation for their projected expenses and revenues from the operation due to variability in …

Efficacy Of Beta-Resorcylic Acid To Reduce Campylobacter Jejuni In Pre-Harvest And Post-Harvest Poultry, Basanta Raj Wagle

Graduate Theses and Dissertations

Campylobacteriosis is one of the leading foodborne illnesses in United States, and is associated with the consumption of poultry and poultry products. Reducing Campylobacter in these species will reduce the burden of this disease. Unfortunately, most strategies employed to reduce Campylobacter in poultry have either not been successful or produced inconsistent results. One potential control strategy is the use of β-resorcylic acid (BR), a phytophenolic compound classified by the US FDA as "Everything Added to Food in the United States" (EAF 3045) and is therefore deemed safe for consumption. This compounds has antibacterial activity against Salmonella, however, its efficacy to …

Divergent Selection For Four-Day Relative Breast Yield And The Effect Of Thermal Manipulations On Growth Characteristics On Lines Selected For Different Processing Dates., James Grant Mason

Graduate Theses and Dissertations

Genetic selections currently utilized in the poultry industry have been highly successful in promoting broiler growth rate and yield. However, these selections may have come at the expense of broiler physiology, as evidenced by an increase in physiological disorders. To address this experimentation was undergone to develop a novel method of selection to promote growth with minimal physiological impact and to assess how a new embryonic technique affects growth in broiler lines exhibiting different growth rates.

In the first experiment, a random bred control (RAN) broiler line was divergently selected for four-day relative breast yield (BY4) resulting in the high …


Intestinal Inflammation Model Inducing Gut Leakage By Different Methods In Broiler Chickens Using Fitc-D As A Marker, Eduardo Vicuna May 2015

Intestinal Inflammation Model Inducing Gut Leakage By Different Methods In Broiler Chickens Using Fitc-D As A Marker, Eduardo Vicuna

Graduate Theses and Dissertations

Traditionally, antibiotic growth promoters (AGP) have been used in food animals to reduce enteric inflammation and maintain intestinal homeostasis, thus improving performance. Due to increasing restrictions regarding the use of AGP, precise and high throughput enteric inflammation models and markers to search for effective alternatives are urgently needed. Oral administration of fluorescein isothiocyanate dextran (FITC-d) and its passage into blood can be used as a marker for tight junction permeability. FITC-d is a large molecule (3-5 kDa) which does not usually leak through the intact gastrointestinal tract barrier. However, when conditions disrupt the tight junctions between epithelial cells, the FITC-d …

Assessment Of Workers Exposure To Ammonia In Animal Facilities At Walter C. Todd Agricultural Research Center, Nacogdoches, Texas, Ahmad F. Nasser, Sheryll B. Jerez

Bright Ideas Conference

Poultry, swine, and equine animal facilities are all considered as Concentrated Animal Feeding Operations (CAFOs). All these CAFOs are emission sources of gases and other pollutants which have negative impacts on the environment, human health, and animal health as well. One of those gases is Ammonia (NH3), which is a colorless, highly irritating gas with a pungent, suffocating odor, and if inhaled in high concentrations, it may cause harm to the human body and the function of lungs. Personal exposure to ammonia was assessed for six workers in the three animal facilities: poultry, swine, and equine. Two workers from each …

Spatial And Temporal Relationships Between Forest Bird Declines And Prevalence Of The Hemlock Woolly Adelgid In The Northeastern United States, Julie E. Blum, Andrew M. Wilson

Student Publications

The eastern hemlock (Tsuga canadensis) is a vital foundation tree species throughout the eastern United States, providing essential structural diversity and habitat for more than 120 different animal species. Within the past few decades, T. canadensis has undergone significant declines that are largely associated with the hemlock woolly adelgid (HWA; Adelges tsugae), an exotic, aphid-like insect native to East Asia. From the 1970s to present day, the HWA has spread throughout southern New England, large portions of the Mid-Atlantic region, and parts of Tennessee and the Carolinas. Research has shown that loss of the eastern hemlock is …

A Feasibility Study Of Using Unmanned Aerial Vehicles To Survey Avian Abundance By Using Audio Recording, Janine M. Barr, Andrew M. Wilson

Student Publications

Roadside counts are commonly used to assess songbird abundance, but they result in oversampling habitat edges and underrepresenting core habitats, areas of steep terrain, and wetlands. Accessing off-road habitats can be logistical challenging and time-consuming, resulting in low survey efficiency. Aerial ecological surveys, using unmanned aerial vehicles (UAVs, or drones) have already proven to be valuable in wildlife monitoring. Previous studies have used photography or videography to provide permanent documentation of wildlife surveys through low altitude aerial imagery. A significant advantage of UAVs over manned aircraft is their greater safety and lower costs. We propose that UAVs can also be …
