Theses and Dissertations
The World Health Organization, estimated that 22.9% of children under the age of 5 are stunted. The etiology of stunting is multifactorial and is associated with poor linear growth, villous atrophy, dysbiosis, and increased intestinal permeability. Inclusion of rye in poultry diets induces nutrient deficiencies and increases intestinal permeability, dysbiosis and decreases growth rates. The objective of this dissertation was to determine if chickens consuming a rye based diet exhibited a similar pathophysiology of stunted children to develop a relevant animal model. Therefore, early or late phase malnutrition was induced determine the effects of malnutrition on performance, bone mineralization ...

Gulls, 2018 USDA, Wildlife Services
Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans
Wildlife Damage Management Technical Series
Abundant gull (Figure 1) populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to ...
Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, 2018 University of Arkansas, Fayetteville
Enhancing Quality Of Life Through Foreign Direct Investment In Northern Mozambique, Sarah-Beth Delay
Agricultural Economics and Agribusiness Undergraduate Honors Theses
Foreign Direct Investment (FDI) has the potential to increase economic activity and improve GDP growth in low-income countries, but can hinder economic development (quality of life improvements) if not sustainable and holistic in manner. Africa serves as a host to many cases of FDI focused on economic growth, but not necessarily improving the quality of life for its citizens. FDI has spread throughout the African continent, where many countries are well endowed with natural resources, like minerals and coal. These economies have experienced rapid GDP growth with few benefits reaching citizens of the host country. Mozambique is a low-income country ...

Microbiome Of Commercial Broilers Through Evisceration And Immersion Chilling, John A. Handley
Theses and Dissertations
The United States poultry industry generated 38.6 billion pounds (17,500 metric ton) of meat in 2014 which averaged to 121 pounds (55 kg) per individual of the U.S that same year. Of that meat generated by the poultry industry, an estimated 1 million cases of Salmonellosis will occur. Out of the 1 million cases approximately 40, 000 to 50,000 will be confirmed cases by the CDC. Recently, the USDA has requested changes in the inspection process and are currently allowing processors more freedom to utilize innovation to drive the increase in safer and more desirable foods ...

The Effect Of Magnetic Water On Feed Conversion Ratio, Body Weight Gain, Feed Intake And Livability Of Male Broiler Chickens, Kenia Mitre
Poultry Science Undergraduate Honors Theses
Passing water through a magnetic field has been shown to have positive effects in agricultural activities such as crops, cattle and poultry production (Ali, Samaneh and Kavakebian, 2014). Several experiments performed in Middle Eastern countries have evaluated the effect of magnetizing drinking water on poultry performance, but results are inconsistent. The current project was conducted to evaluate the effect of magnetizing the drinking water on key aspects of poultry production such as Feed Conversion Ratio, Body Weight Gain, Feed Intake and Livability. Four hundred and forty-nine male Cobb-500 chicks were randomly placed in 6 replicate pens for each of 3 ...
Effects Of Dimethyl Sulfoxide And Glycerol Based Vitrification Protocols On Zona Pellucida Hardening In Mature Bovine Oocytes, 2018 Louisiana State University
Effects Of Dimethyl Sulfoxide And Glycerol Based Vitrification Protocols On Zona Pellucida Hardening In Mature Bovine Oocytes, Kaci Denise Rogers
LSU Master's Theses
Zona pellucida hardening is a natural process that occurs after oocyte fertilization to prevent polyspermic fertilization and to protect embryonic development. Pre-fertilization hardening of the zona pellucida however, decreases fertilization rates. Cryoprotectants have also been shown to negatively affect fertilization rates, one possible mechanism of which being through zona hardening. This experiment was conducted to determine the effect of different cryoprotectants on hardening of the zona pellucida using fresh mature bovine oocytes and vitrified mature bovine oocytes. Oocytes were post-slaughter from mixed breed cows. After collection, oocytes were randomly assigned to three cryoprotectant treatment groups: dimethyl sulfoxide (DMSO), glycerol or ...

Comparative Response Of The Hepatic Transcriptomes Of Domesticated And Wild Turkey To Aflatoxin B1, Kent M. Reed, Kristelle M. Mendoza, Juan E. Abrahante, Roger A. Coulombe
Animal, Dairy, and Veterinary Science Faculty Publications
The food-borne mycotoxin aflatoxin B1 (AFB1) poses a significant risk to poultry, which are highly susceptible to its hepatotoxic effects. Domesticated turkeys (Meleagris gallopavo) are especially sensitive, whereas wild turkeys (M. g. silvestris) are more resistant. AFB1 toxicity entails bioactivation by hepatic cytochrome P450s to the electrophilic exo-AFB1-8,9-epoxide (AFBO). Domesticated turkeys lack functional hepatic GST-mediated detoxification of AFBO, and this is largely responsible for the differences in resistance between turkey types. This study was designed to characterize transcriptional changes induced in turkey livers by AFB1, and to contrast the response of domesticated (susceptible ...

All Regis University Theses
Life in a zoo brings a score of stressors into the lives of captive animals, including artificial light, crowds of visitors, and increased noise levels. Stress especially impacts captive birds, and continued exposure to these stressors can negatively affect birds’ reproductive success and overall well-being. Staff at the Denver Zoo noticed increased aggression between a male and female pair of great Indian hornbills during the winter of 2016. This behavioral shift coincided with Zoo Lights, a holiday event that results in the hornbills’ exhibit remaining open to the public for approximately four extra hours through the entire month of December ...

Mitigating Ammonia And Pm Generation Of Cage-Free Henhouse Litter With Solid Additive And Liquid Spray, Lilong Chai, Hongwei Xin, Yang Zhao, Tong Wang, Michelle L. Soupir, Kai Liu
Agricultural and Biosystems Engineering Publications
A number of chain restaurants, retailers, and grocers in the U.S. have pledged to source only cage-free (CF) eggs in the foreseeable future (e.g., by 2025) due to marketing reasons or concerns over animal welfare. However, CF housing has some inherent challenges, and a predominant one is poor air quality, i.e., ammonia gas (NH3) and particulate matter (PM), and increased emissions. Spraying a liquid agent such as electrolyzed water (EW) can effectively suppress PM generation of CF henhouse litter. However, liquid spray can enhance NH3 generation because it increases the litter moisture content (LMC). Application of acidic ...

Amino Acid Digestibility Of A High Protein Ddgs Product In Broilers, Krysten Fries, Elizabeth Bobeck
Animal Industry Report
Distiller’s dried grains with solubles (DDGS) are a common feedstuff in poultry diets, however, digestibility estimates vary with production method and strain (broiler vs layer). The objective of this study was to determine the amino acid digestibility of 34.1% (as fed) high-protein DDGS in straight-run Cobb 500 broiler chickens. Calculated standardized ileal amino acid digestibility (SIAAD) of indispensable amino acids (AA) ranged from 81.20 to 90.41%. The SIAAD of dispensable AA ranged from 16.16 to 89.78%. The digestibility of limiting AA in HiP DDGS was greater than reported digestibility values of the same AA ...
Evaluation Of A High Protein Ddgs Product On Broiler Performance, 2018 Iowa State University
Evaluation Of A High Protein Ddgs Product On Broiler Performance, Krysten Fries, Elizabeth Bobeck
Animal Industry Report
Dried distiller’s grains with solubles (DDGS) are commonly fed at an inclusion of 10% or less in broiler diets with the added benefit of an improved ability to utilize the available nutrients compared to layers fed the same inclusion. Combined with intentional changes to processing to enhance the nutritional quality of DDGS, there is the potential to increase the utilization of DDGS when fed to broilers. The objective of this study was to determine the effects of feeding up to a 20% inclusion of high protein DDGS (HiP DDGS) on broiler performance in straight-run Cobb 500 broiler chickens. Birds ...

Animal Industry Report
The future of agriculture presents unique challenges, including producing more food using fewer resources, as global climate changes. Genetic selection and genomic data continue to be valuable tools in animal agriculture that will help address these challenges. We used genomic data and statistical analysis to investigate response of laying hens to heat stress. Hens of the Hy-Line W-36 female parent line were exposed to a daily cyclic heat challenge from 24 to 28 weeks of age. Eggs were collected daily in two-week periods (pre heat, 2 and 4 weeks post heat) for measurements of egg weight. Egg weights and feed ...
Integration Of Host And Virus Gene Expression For Chickens Response To Avian Leukosis Virus Challenge, 2018 Iowa State University
Integration Of Host And Virus Gene Expression For Chickens Response To Avian Leukosis Virus Challenge, Xi Lan, John C.F. Hsieh, Haibo Liu, Susan J. Lamont, Qing Zhu
Animal Industry Report
The tumorigenesis caused by avian leukosis virus (ALV) occurs through a complex regulatory architecture. , We applied a novel methodology to jointly analyze four different types of datasets: mRNA expression, the associated regulatory factors of miRNA and lncRNA, and ALV gene expression. The pathway analysis shows that combined analysis produced more informative results than single data-type analyses, and the co-expression network analysis found key elements involved in the host-pathogen interaction. The integration of multiple data sources yielded deeper insights into the pathogenesis of the virus and the host immune response.
More Mhc-Like Class I Y Mrna Detected In Relatively Resistant Fayoumis Than Susceptible Leghorns, 2018 Iowa State University
More Mhc-Like Class I Y Mrna Detected In Relatively Resistant Fayoumis Than Susceptible Leghorns, Melissa S. Deist, Rodrigo A. Gallardo, David A. Bunn, Terra R. Kelly, Jack C. M. Dekkers, Huaijun Zhou, Susan J. Lamont
Animal Industry Report
The inbred chicken lines Fayoumi and Leghorn have been shown to be relatively resistant and susceptible, respectively, to Newcastle disease virus (NDV). In this experiment we detected higher gene expression levels of MHC-like class I Y (MHCIY) in the Fayoumi trachea, lung, and Harderian gland of NDV challenged and nonchallenged birds across multiple time points. MHC region is important to the immune system and is often associated with resistance to pathogens. This gene may be associated with the Fayoumis’ resistant phenotype.
