Efficacy Of A Novel Intranasal Zinc Solution On The Microbiome, Health, And Growth Performance Of High-Risk, Newly Received Stocker Cattle, Makenzie Foster
Efficacy Of A Novel Intranasal Zinc Solution On The Microbiome, Health, And Growth Performance Of High-Risk, Newly Received Stocker Cattle, Makenzie Foster
Graduate Theses and Dissertations
The objective of this study was to determine if using an intranasal zinc (Zn) solution would impact health and growth performance of high-risk stocker cattle. Male beef calves (n = 239; 3 arrival dates [block]; initial BW = 276 ± 2.4 kg) were stratified by arrival gender and BW and assigned to 1 of 2 treatments: 1) treated with 3 ml of a Zn solution containing 36.24 mg of Zn administered intranasally, or 2) control, in which calves were not treated. Calves were observed daily and if exhibiting signs of morbidity and a rectal temperature ≥ 40° C they were …
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 …
The Efficacy Of Probiotic Bacterial Isolates In Reducing Cecal Camylobacter Colonization In Broiler Chickens, Komala Arsi
The Efficacy Of Probiotic Bacterial Isolates In Reducing Cecal Camylobacter Colonization In Broiler Chickens, Komala Arsi
Graduate Theses and Dissertations
Campylobacter is the leading cause of foodborne illness worldwide and human illnesses are often associated with consumption of poultry or poultry products. Many strategies have been tried to eliminate Campylobacter from poultry with limited success. One of the strategies to reduce Campylobacter colonization in poultry is by use of probiotics. We conducted 2 separate studies to evaluate the efficacy of probiotics against Campylobacter in broiler chickens. For our first study, GRAS (Generally Regarded as Safe) bacteria were isolated from healthy chickens and tested their efficacy against Campylobacter in vitro. Twenty six isolates with in vitro anti-Campylobacter activity were …
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, …
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
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 …
The Impact Of Bovine Spongiform Encephalopathy (Bse) On World Protein Supply, Jarrod Kersey
The Impact Of Bovine Spongiform Encephalopathy (Bse) On World Protein Supply, Jarrod Kersey
Graduate Theses and Dissertations
As world population, per capita income and urbanization increase, consumption of meat, poultry, milk and eggs will continue to rise to meet the needs of approximately nine billion people in 2050. Global beef, pig and chicken production and per capita consumption increased between 2000 and 2010, with growth in broiler production and consumption outpacing both beef and swine. The increased production and consumption requires readily available feed ingredients in regions where animal production is rapidly developing. Animal-based protein feed ingredients are often difficult to move from country to country due to real or perceived risk of animal disease. Zoosanitary standards …
