Efficacy Of Beta-Resorcylic Acid To Reduce Campylobacter Jejuni In Pre-Harvest And Post-Harvest Poultry, Basanta Raj Wagle
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 …
Energetic Costs Of Aggression In The Northern Cardinal, Sarah K. Wright
Energetic Costs Of Aggression In The Northern Cardinal, Sarah K. Wright
Honors Program Theses
Territorial aggression during the nonbreeding season has not been sufficiently studied, especially in a natural system. There has been some evidence to suggest that the steroid hormone precursor, dehydroepiandrosterone (DHEA) may regulate male aggression during the nonbreeding season, rather than testosterone. This study aimed to investigate the effects of energy status (through food supplementation) on nonbreeding aggression in the Northern Cardinal and add to the pre-existing evidence of a DHEA-mediated mechanism of aggression. It was hypothesized that if aggression was maintained for an extended period of time, metabolite levels would favor energy usage (more glycerol and less triglycerides) compared to …

Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Graduate Theses and Dissertations
Research trials were conducted to evaluate the effects of different levels of dietary grain sorghum on broiler live performance, carcass yield and shank (leg) and breast skin coloring. Iso-caloric diets were formulated where sorghum replaced corn at rates of 0% (control), 20, 40, 60, 80 and 100% for a total of 6 diets. For each of the two trials, 1500 Cobb 500 male broiler chicks were randomly allocated to 60 pens with 25 birds per pen (10 pens/diet) and grown to 46 days for the first research trial and 41 days for the second. There were no differences (P>.05) …

Migratory birds often form flocks on their wintering grounds, but important details of social structure such as the patterns of association between individuals are virtually unknown. We analysed networks of co-membership in short-term flocks for wintering golden-crowned sparrows (Zonotrichia atricapilla) across three years and discovered social complexity unsuspected for migratory songbirds. The population was consistently clustered into distinct social communities within a relatively small area (~ 7 ha). Birds returned to the same community across years, with mortality and recruitment leading to some degree of turnover in membership. These spatiotemporal patterns were explained by the combination of space …

Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
An increasing concern in poultry nutrition is the effects of mycotoxins in contaminated grain. Several new products have come onto the market that chemically bind these toxins preventing mycotoxicosis. However, many of these products have not been tested for safety if accidently overfed to broiler breeders. In order to simulate a feed mixing error at a feed mill, Improved Milbond-TX® was overfed to broiler breeders to see if this would cause any negative effects on bird performance. A typical corn-soybean based diet supplemented with Milbond-TX mycotoxin binder at three different levels of inclusion (0%, 0.5%, and 1%) was fed to …

Identification Of Biomarkers Associated With Ascites Incidence In Broilers, Kaylee Rowland
Identification Of Biomarkers Associated With Ascites Incidence In Broilers, Kaylee Rowland
Graduate Theses and Dissertations
Poultry is key in genetic research due to breeding feasibility, relatively short generation interval, and distinct phenotypes. It is estimated that 8% of broiler deaths annually can be attributed to ascites, an economically important disease that has been challenging the industry for the past 2 decades. Genetically selected ascites resistant (RES) and susceptible (SUS) chicken lines have been established and maintained by the University of Arkansas, Fayetteville. Intensive research efforts have been made to reveal physiological and biochemical characteristics for the incidence of ascites. Since the whole genome of the major ancestral chicken, the Red Jungle Fowl, has been sequenced, …
Evaluation Of Water Sanitation Options For Poultry Production, Pramir Maharjan
Evaluation Of Water Sanitation Options For Poultry Production, Pramir Maharjan
Graduate Theses and Dissertations
An evaluation of poultry farm water supplies was conducted to determine the value and impact of water system sanitation practices in commercial broiler houses on microbial levels. Water line cleaning between flocks using concentrated disinfectant solution before placing chicks reduced biofilms retained in the lines to a safe level. Occasional microbial surges were noticed during different points of flock grow-out period even when daily water sanitation was present indicating water is highly susceptible to microbial contamination. However, the daily water sanitation practice controlled the occasional microbial surges in water from sustaining and kept drinking water to a microbiologically acceptable level. …
Changes In Avian Vocalization Occurrence And Frequency Range During The Winter, Amy I. Oden
Changes In Avian Vocalization Occurrence And Frequency Range During The Winter, Amy I. Oden
School of Natural Resources: Dissertations, Theses, and Student Research
Human population expansion has led to an increase in vehicle traffic and therefore vehicle noise. Traffic and traffic noise has been shown to affect avian abundance, breeding success, density and species diversity on the landscape. Documented changes in avian vocalizations due to traffic noise include shifts in amplitude, frequency, rate, timing, and duration of vocalizations along with a number of behavioral adaptations. During the winters of 2011–2012 and 2012–2013, we recorded and measured the “chick-a-dee” vocalization of Black-capped Chickadees (Poecile atricapillus) and the “po-ta-to-chip” vocalization of American Goldfinches (Spinus tristis) to determine …

Genetic Analysis Of The Promoter Region Of The Serotonin Receptor 5ht2b And Its Contribution To Pulmonary Hypertension Syndrome In Broiler-Type Chickens, Khaloud Awada Alzahrani
Graduate Theses and Dissertations
Pulmonary Arterial Hypertension (PAH) is a sever disorder characterized by high pulmonary artery pressure and pulmonary vascular resistance along with specific histological changes. Idiopathic PAH is a human disease of unknown origin that showed common characteristics to PHS/ascites in chicken. PHS/ascites is a condition found in broilers causing right ventricular hypertrophy, valvular insufficiency, increased venous pressure, variable liver changes, accumulation of fluids in the abdominal cavity, and finally lung and heart failure. Currently, there is no acceptable animal model for human PAH. Our group has been validating the chicken as the medical animal model for human PAH, thus we have …
Effects Of Using Canola Meal As A Protein Source In Broiler Diets, Charles Danny Bradley Jr
Effects Of Using Canola Meal As A Protein Source In Broiler Diets, Charles Danny Bradley Jr
Graduate Theses and Dissertations
Six experiments were conducted to evaluate the response of broilers fed canola meal. Experiment 1 assessed performance and carcass yields when broilers were fed various combinations of canola and soybean meal in nutritionally balanced diets based on digestible amino acid values. The results suggested that canola meal can be used in isocaloric diets as a partial replacement for Soybean meal.
Experiment 2 assessed broiler performance and carcass yields when using various levels of canola meal in broiler diets with a constant level of supplemental poultry oil. The resulting data suggested when diets are formulated with a constant level of supplemental …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Poultry production holds an important place in Arkansas economically and as a food source. The importance of poultry production ultimately hinges on the demands of the consumer. With this in mind, this study surveyed consumers to assess their perceptions of poultry production in Arkansas. The instrument, used to survey consumers, was created by the researcher and an expert committee at the University of Arkansas. Consumers were interviewed through direct communication at grocery stores in northwest Arkansas. Data gathered from the study were analyzed for descriptive and correlational statistics. Two key findings were that consumers were unsure about the use of …
The Effect Of Visual Wulst Lesions And Trigeminal Nerve Sectioning On The Discrimination Of Magnetic Inclination In The Homing Pigeon (Columba Livia), Merissa Acerbi
Honors Projects
The ability of homing pigeons to return to their loft from unknown places has fascinated scientists for centuries. It is well established that homing pigeons, like migratory birds, posses an innate magnetic inclination compass to determine direction by measuring the angle between the magnetic field vector and the Earth's surface. Recent work has indicated that the avian magnetic compass is light mediated and appears to mediate magnetic information to the brain. This occurs via a visual pathway with processing in the visual Wulst area of the forebrain. There is, however, also evidence from other avian species that magnetic direction may …

Comparative Response Of Different Broiler Genotypes To Dietary Nutrient Levels, Franco Javier Mussini
Graduate Theses and Dissertations
ABSTRACT
Three studies were conducted to evaluate how the broiler has changed over the years due to intense genetic selection. Four different broiler genotypes, one unselected since the 1950's (HER) representing the old meat-type bird and three current strains (Ross 308, Ross 708, and a test product (TY)) were studied. Differences in growth, morphometry, and response in performance and processing yield to different nutrient levels were studied.
Experiment 1 evaluated growth and morphometric analysis. Birds of each strain were killed weekly from day 7 to day 56, necropsied and cut up parts and organs weighed. Measurement of small intestine segments …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts
Research outputs 2012
Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen
Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen
Great Plains Research: A Journal of Natural and Social Sciences (through 2013)
Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …

Sequence Analysis Of The Angiotensin Ii Type 1 Receptor (Agtr1) Gene For Mutations Contributing To Pulmonary Hypertension In The Chicken (Gallus Gallus), John Russell Burks
Inquiry: The University of Arkansas Undergraduate Research Journal
Our multidisciplinary group at the University of Arkansas has been investigating the suitability of the chicken as a medical model for pulmonary arterial hypertension (PAH) in humans. There are several forms of PAH in humans arising from elevated pulmonary arterial pressure and pulmonary vascular resistance. Spontaneous cases of PAH are known as idiopathic PAH (IPAH), where the exact physiological causes are not known. IPAH patients that do not respond to standard treatments have a prognosis of only a few years. Currently, there is no acceptable animal model for IPAH. As part of our effort to pursue the chicken as model …
Information Acquisition And Sociality Among Migratory Birds, Zoltán Németh
Information Acquisition And Sociality Among Migratory Birds, Zoltán Németh
Dissertations
Information use is a key feature of adaptive behavior: the better informed an individual, the better it is able to adjust its behavior to meet the demands of a variable world. Therefore, most animals attempt to reduce environmental uncertainty by gathering information when it is available. However, tracking unpredictable ecological factors may carry costs as individuals invest valuable time and energy in the process of information acquisition. Social learning (i.e., use of social information inadvertently produced by other individuals) enables the individual to gain rapid and more complete assessment of its novel environment. This process may be particularly important for …

The efficacy of killed vaccines generally is not equal to live vaccines. However, due to safety and ease of production, they remain a vital part of controlling and preventing diseases. In this study, the immune response to four different vaccination preparation techniques for the agent of bordetellosis of turkeys, Bordetella avium (BA), was compared. Preparation/inactivation techniques included (1) formalin inactivation, (2) opsonization of formalin-inactivated BA, (3) buffered acetic-acid BA inactivation, or (4) opsonization of buffered acetic-acid-inactivated BA. Non-adjuvated suspensions containing equal antigen mass were administered subcutaneously (0.2 mL) at day-of-hatch in all cases. For each treatment (N=40/treatment), plasma samples were …

This paper presents further results on the food ecology of the eagle owl in western Mongolia for the years 1984 to 1992. Additional to the already known sites we investigated two new resting places. At least 27 mammal and 17 bird species were recorded. The results confirm previous studies. Small to medium sized mammals (Cricetidae, Dipodidae, Arvicolidae) dominate the prey of the eagle owl whereas birds and invertebrates are less important.
