Climate Dependent Heat Stress Mitigation Modeling For Dairy Cattle Housing, Katlyn R. DeVoe, Steven J. Hoff, Brett C. Ramirez, Lance H. Baumgard 2019 Iowa State University

Climate Dependent Heat Stress Mitigation Modeling For Dairy Cattle Housing, Katlyn R. Devoe, Steven J. Hoff, Brett C. Ramirez, Lance H. Baumgard

Brett Ramirez

Dairy cattle are susceptible to heat stress with reported milk production loss exceeding 1.2 billion dollars in 2010. Heat stress occurs when the local thermal environment prevents adequate dissipation of metabolic heat production over extended periods. Implementing mitigation strategies in order to reduce heat stress has been a crucial need as dairy housing has transitioned from pasture to indoor housing systems. In order to maximize production, producers need the most effective cooling system to reduce heat stress. A heat stress mitigation model was developed using TMY3 data sets as inputs. The objectives of this research were to: (i) analyze ...

The Western dietary pattern can alter the gut microbiome and cause obesity and metabolic disorders. To examine the interactions between diet, the microbiome, and obesity, we transplanted gut microbiota from lean or obese human donors into mice fed one of three diets for 22 weeks: (1) a control AIN93G diet; (2) the total Western diet (TWD), which mimics the American diet; or (3) a 45% high-fat diet-induced obesity (DIO) diet. We hypothesized that a fecal microbiome transfer (FMT) from obese donors would lead to an obese phenotype and aberrant glucose metabolism in recipient mice that would be exacerbated by consumption ...

Zika Virus Associated Pathology And Antigen Presence In The Testicle In The Absence Of Sexual Transmission During Subacute To Chronic Infection In A Mouse Model, Chad S. Clancy, Arnaud J. Van Wettere, John D. Morrey, Justin G. Julander

John D. Morrey

Zika virus (ZIKV) is an arboviral infection that has been shown to be sexually transmitted. The study outlined herein aims to determine if accessory sex glands and epididymal epithelial cells are sources of viral persistence in subacute and chronic ZIKV infection, and if infection of these organs is important in sexual transmission during long-term (chronic) infection. Male interferon type I receptor knockout (Ifnar−/−) mice were challenged with ZIKV and reproductive tissues were harvested 14 and 35 days post infection (DPI) for inoculation studies and 14, 35 and 70 DPI for histopathology. Artificial insemination fluid derived from epididymal flush and seminal ...

Altered Gene Response To Aflatoxin B1 In The Spleens Of Susceptible And Resistant Turkeys, Kent M. Reed, Kristelle M. Mendoza, Roger A. Coulombe, Jr. 2019 University of Minnesota

Altered Gene Response To Aflatoxin B1 In The Spleens Of Susceptible And Resistant Turkeys, Kent M. Reed, Kristelle M. Mendoza, Roger A. Coulombe, Jr.

Roger A. Coulombe, Jr.

Susceptibility and/or resistance to aflatoxin B1 (AFB1) is a threshold trait governed principally by glutathione S transferase (GST)-mediated detoxification. In poultry, domesticated turkeys are highly sensitive to AFB1, most likely due to dysfunction in hepatic GSTs. In contrast, wild turkeys are comparatively resistant to aflatoxicosis due to the presence of functional hepatic GSTAs and other possible physiological and immunological interactions. The underlying genetic basis for the disparate GST function in turkeys is unknown as are the broader molecular interactions that control the systemic response. This study quantifies the effects of dietary AFB1 on gene ...

Abby D. Benninghoff

Crystalline silica (cSiO2) is a widely recognized environmental trigger of autoimmune disease. In the lupus-prone female NZBWF1 mouse, airway exposure to cSiO2 triggers pulmonary ectopic lymphoid neogenesis, systemic autoantibody elevation, and glomerulonephritis. Here we tested the hypothesis that upregulation of adaptive immune function genes in the lung precedes cSiO2-triggering of autoimmune disease in this model. The study include three groups of mice, as follows: (1) necropsied 1 d after a single intranasal instillation of 1 mg cSiO2 or vehicle, (2) necropsied 1 d after four weekly single instillations of 1 mg cSiO2 or vehicle ...

Validation Of A Commercial Automated Body Condition Scoring System On A Commercial Dairy Farm, Israel L. Mullins, Carissa M. Truman, Magnus R. Campler, Jeffrey M. Bewley, Joao H. C. Costa

Animal and Food Sciences Faculty Publications

Body condition scoring (BCS) is the management practice of assessing body reserves of individual animals by visual or tactile estimation of subcutaneous fat and muscle. Both high and low BCS can negatively impact milk production, disease, and reproduction. Visual or tactile estimation of subcutaneous fat reserves in dairy cattle relies on their body shape or thickness of fat layers and muscle on key areas of the body. Although manual BCS has proven beneficial, consistent qualitative scoring can be difficult to implement. The desirable BCS range for dairy cows varies within lactation and should be monitored at multiple time points throughout ...

A seven-year-old spayed female Labrador retriever presented for necropsy following an acute history of thrombocytopenia, anemia, leukocytosis and abdominal effusion. A 2 × 3 × 10 cm, cylindrical to tubular, mottled red-to-tan mass extended from the caudal pelvic cavity caudally and ventrally under the dermis along the caudal aspect of the left pelvic limb adjacent to the semimembranosus and semitendinosus musculature. Histologic examination of the mass revealed a singular central lumen lined by urothelium that multifocally transitioned into non-keratinizing, stratified squamous epithelium associated with few hair follicles and sweat glands. The lumen was surrounded by a dense collagenous stroma containing numerous, variably ...

In 2008, a consortium led by the Agricultural Research Service (ARS) and the National Institute for Food and Agriculture (NIFA) published the “Blueprint for USDA Efforts in Agricultural Animal Genomics 2008–2017,” which served as a guiding document for research and funding in animal genomics. In the decade that followed, many of the goals set forth in the blueprint were accomplished. However, several other goals require further research. In addition, new topics not covered in the original blueprint, which are the result of emerging technologies, require exploration. To develop a new, updated blueprint, ARS and NIFA, along with scientists in ...

Development of antiviral drug resistance is a continuous concern for viruses with high mutation rates such as influenza. The use of antiviral drugs targeting host proteins required for viral replication is less likely to result in the selection of resistant viruses than treating with direct-acting antivirals. The iminosugar UV-4B is a host-targeted glucomimetic that inhibits endoplasmic reticulum α-glucosidase I and II enzymes resulting in improper glycosylation and misfolding of viral glycoproteins. UV-4B has broad-spectrum antiviral activity against diverse viruses including dengue and influenza. To examine the ability of influenza virus to develop resistance against UV-4B, mouse-adapted influenza virus was passaged ...

Evaluation Of Casein Hydrolysate As An Alternative Dry-Off Treatment And Milk Quality Management Tool In Dairy Cows, Justine Elena Britten

All Graduate Theses and Dissertations

Mastitis, an infection of the mammary gland, is the most common and expensive animal health problem for the dairy industry and affects every dairy farm to some degree. This disease complex is painful for dairy cows, increases the on-farm use of antibiotics, presents a threat to milk quality and is a waste of time, money and milk production. Each year, the dairy industry loses as much as a billion dollars to mastitis.

Many cows will experience mastitis at least once during a lactation cycle and some animals will develop recurring mastitis episodes in a single mammary quarter. These mastitic quarters ...

Ruminal Protection And Intestinal Availability Of Rumen-Protected Methionine And Lysine In Lactating Dairy Cows, Sara Menchu

All Graduate Theses and Dissertations

Rumen protected Methionine (MET) and Lysine (LYS) are critical for milk protein synthesis in dairy cows. N-acetyl-L-methionine (NALM) is a MET derivative that consists of L-Met protected with an acetyl group that is attached to the α-amino group.N-acetyl-L-lysine (NALL) is a LYS derivative that is similarly protected. The objectives of these studies were to quantify the gastrointestinal availability of NALM and NALL. Three experiments were run as 3 × 3 Latin square using 3 second lactation Holstein cows that have been fitted with cannulas in the rumen and duodenum. The cows were fed diets containing the supplements for two weeks ...

Standardization And Extrapolation Of Icing Stability, Shelf Life, And Safety Under Heat Abuse, Jaden Castinado

Kansas State University Undergraduate Research Conference

Inquiries from Kansas citizens requested information on the stability, shelf life, and safety of icings on baked goods after prolonged exposure to heat without refrigeration, often common at county and state fairs. Methods include compiling a sample of icing recipes from Kansas citizens and entering into a database so that recipes could be sorted by factors such as sugar and/or dairy content. A central composite design will then be used to identify trials with variable amounts of sugar, dairy, and sugar with dairy. Current work is focused on creating a concise and navigable database with sufficient data to create ...

Currently, there are no licensed human vaccines or antivirals for treatment of or prevention from infection with encephalitic alphaviruses. Because epidemics are sporadic and unpredictable, and endemic disease is common but rarely diagnosed, it is difficult to identify all populations requiring vaccination; thus, an effective post-exposure treatment method is needed to interrupt ongoing outbreaks. To address this public health need, we have continued development of ML336 to deliver a molecule with prophylactic and therapeutic potential that could be relevant for use in natural epidemics or deliberate release scenario for Venezuelan equine encephalitis virus (VEEV). We report findings from in vitro ...
