Nuclear Factor [Erythroid-Derived 2]-Like 2’S (Nfe2l2) Gene Expression In Feed Efficiency And Oxidative Stress In Avian Muscle, Devin Wayne Cook
Nuclear Factor [Erythroid-Derived 2]-Like 2’S (Nfe2l2) Gene Expression In Feed Efficiency And Oxidative Stress In Avian Muscle, Devin Wayne Cook
Graduate Theses and Dissertations
Oxidative stress may play a role in the phenotypic expression of feed efficiency (FE). The transcription factor NFE2L2 (nuclear factor erythroid-derived 2-like 2) coordinates antioxidant response to oxidative stress and its activity is tightly regulated in part by KEAP1 (Kelch like-ECH protein 1) and the E3 ligase CUL3 (Cullin3). Thus, one objective was to determine mRNA expression of NFE2L2, KEAP1, and CUL3 as well as three antioxidant targets [glutathione peroxidase (GPx-1), superoxide dismutase 1 (SOD1), and superoxide dismutase 2 (SOD2)] in breast muscle of immature pedigree broiler males (8 wk), immature Japanese quail males (4 wk) divergently selected for high …

Avian influenza viruses (AIVs) continue to pose a global threat. Waterfowl are the main reservoir and are responsible for the spillover of AIVs to other hosts. This study was conducted as part of routine surveillance activities in Bangladesh and it reports on the serological and molecular detection of H5N1 AIV subtype. A total of 2169 cloacal and 2191 oropharyngeal swabs as well as 1725 sera samples were collected from live birds including duck and chicken in different locations in Bangladesh between the years of 2013 and 2014. Samples were tested using virus isolation, serological tests and molecular methods of RT-PCR. …
Characterization Of Broiler Lines Divergently Selected For Breast Muscle Color, Sara Katherine Orlowski
Characterization Of Broiler Lines Divergently Selected For Breast Muscle Color, Sara Katherine Orlowski
Graduate Theses and Dissertations
An increase in the consumption of poultry has generated an increase in demand for higher yielding broilers. This has led to an increase in atypical meat and issues with appearance. Color is a direct result of a pH decline as meat goes through rigor mortis with meat generally becoming lighter. If the pH declines too rapidly or too slowly, meat quality can suffer. Physical properties of meat can be altered by pH. A fast pH decline results in pale meat with decreased tenderness. A slow pH decline can result in darker meat with a reduced shelf-life. With a known relationship …
Comparisons Of Selected Household And Commercial Disinfectants Against Poultry Salmonella Isolates And A Survey Of Internal Parasites In Backyard Poultry In Arkansas, Kayleigh Moyle
Graduate Theses and Dissertations
Backyard and exhibition poultry have been gaining in popularity and as such there has been a large increase in the number of small flocks. As the interaction with poultry has increased, so has the opportunity for diseases and parasites, for both birds and people. One of the major zoonotic illnesses is caused by the bacteria Salmonella, which can be found in commercial and small flocks. Salmonella is the number 2 contributor of foodborne illnesses so its prevalence in commercial flocks is of high concern. Despite improved cleaning, disinfection, and biosecurity practices, there is still potential for disease outbreaks and infections …
Development Of A Biofilm Model For Evaluating Poultry Drinking Water Sanitation Procedures, Pramir Maharjan
Development Of A Biofilm Model For Evaluating Poultry Drinking Water Sanitation Procedures, Pramir Maharjan
Graduate Theses and Dissertations
Enclosed water system has created a minimal sanitation focus leading to biofilm issues which are a source of flock health challenges. A series of in vitro tests were conducted to evaluate biofilm growth on polyvinylchloride (PVC) surfaces when exposed to treated/untreated water sources (test water) that are typically supplied in commercial barns. PVC test coupons (15.16 cm2) were immersed in test water in beakers to grow biofilm. Test water supplies were characterized for microbial, mineral and pH content. Temperature of test water was set at 90 °F (32.2 ᵒC) on d1 and then dropping 1°F each day over 7-day period …
A Molecular Approach To Understanding The Effects Of Original-Xpc On The Modulation Of The Cecal Microbiota And The Survival Of Salmonella In The Poultry Host, Stephanie Roto
Graduate Theses and Dissertations
Salmonella is a foodborne pathogen commonly associated with poultry products; the economic burden to the U.S. is estimated to be approximately $693 million (without factoring in contaminated eggs). Recently, there has been pressure to withdraw sub-therapeutic levels of antibiotics (also known as antibiotic growth promoters; AGP) from poultry due to concern over antibiotic-resistant bacteria spreading to the human population. Therefore, various feed additives have been researched for their ability in providing protection against harmful pathogens and their potential growth promoting effects, both of which were attributes of poultry treated with AGP. This thesis consists of a comprehensive literature review that …

Cfd Model For Ventilation In Broiler Holding Sheds, Christian Heymsfield
Biological and Agricultural Engineering Undergraduate Honors Theses
Broiler production in Arkansas was valued at over $3.6 billion in 2013 (University of Arkansas Extension of Agriculture). Consequently, improvement in any phase of the production process can have significant economic impact and animal welfare implications. From the time poultry leave the farm and until they are slaughtered, they can be exposed to harsh environmental conditions, both in winter and in summer. After road transportation, birds are left to wait in holding sheds once they arrive at the processing plant, for periods of approximately 30 minutes to two hours. This project was interested in this holding shed waiting time during …
Black Soldier Fly Larvae Manual, Haeree H. Park
Black Soldier Fly Larvae Manual, Haeree H. Park
Student Showcase
This manual is a resource for fisheries, hatcheries, and farms of all types that wish to exercise a sustainable management system utilizing black soldier fly larvae through the minimization of waste. Although black soldier fly larvae can be fed to small livestock such as chickens and rodents, this project and manual are tailored specifically to freshwater fish in hopes of closing the significant gap and inefficiencies of fish management and subsequent waste throughout the New England coastal area. There is an evident opportunity to harness black soldier fly larvae’s extraordinary bioconversion of organic matter that can lead to not only …
