Northwest Arkansas Consumer Perceptions Of Poultry Production, Stuart Estes

Agricultural Education, Communications and Technology Undergraduate Honors Theses

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 consumers and the perceptions that drive their purchases. 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. Data showed that consumers were …

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, …

Development Of Rapid Detection Methods And Novel Control Measures For Salmonella In Poultry, Si Hong Park

Graduate Theses and Dissertations

This dissertation consists of three research parts: 1) development of rapid detection methods for foodborne pathogens; 2) immune response of chicken cells against Salmonella and bacteriophage P22; 3) evaluation of novel control measures for poultry productions. In order to develop rapid and accurate detection methods for foodborne pathogens, two types of PCR assays were utilized. Three foodborne pathogens included Campylobacter, Escherichia coli and Salmonella in watershed were qualitatively and quantitatively detected by multiplex PCR and qPCR (chapter 2). Since Salmonella species are commonly present in poultry and poultry products as well as most popular foodborne pathogen in …

An Educational Video And Research Experiment On The Longevity Of Chicken Eggs, Kyle Patrick Mcdonald

Agricultural Education and Communication

The purpose of this project was to create a video designed to educate the public about chicken egg storage and refrigeration. The information in the video was based on a research experiment performed by the author, which was designed to measure the chronological decline of internal egg quality over a ten-week period. By creating an educational video about the longevity of chicken eggs, it is hoped that consumers will learn to keep their eggs past their sell-by dates. This project includes an educational video as well as an outline for a research project.

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 …

Evaluation Of Drug-Resistant Enterobacteriaceae In Retail Poultry And Beef, Agnes Kilonzo-Nthenge, Emily Rotich, Samuel N. Nahashon

Agricultural and Environmental Sciences Faculty Research

There has been increasing concern on the emergence of multidrug-resistant foodborne pathogens from foods of animal origin, including poultry. The current study aimed to evaluate antibiotic-resistant Enterobacteriaceae from raw retail chicken/turkey parts (thigh, wings, breast, and ground) and beef meat (ground and chunks) in Middle Tennessee. Resistance of the collected Enterobacteriaceae to a panel of antibiotics was determined by the Kirby-Bauer disk diffusion test. Retail meats were also assayed for the presence of Salmonella spp. and Escherichia coli O157:H7. Two hundred thirty-seven samples representing 95.2% of the total of 249 samples tested were positive for Enterobacteriaceae. The level of contamination …
