The Effect Of Diet Formulations Containing Different Protein Sources On Energy And Nitrogen Utilization In Lactating Jersey Cows, Kortney Ann Harpestad
The Effect Of Diet Formulations Containing Different Protein Sources On Energy And Nitrogen Utilization In Lactating Jersey Cows, Kortney Ann Harpestad
Department of Animal Science: Dissertations, Theses, and Student Research
It is well understood that lactating dairy cows require metabolizable protein (MP) for milk yield and milk protein synthesis. Diets with conventional feed sources like corn and soybean meal (SBM) may not sufficiently meet all MP and amino acid (AA) requirements so supplementation with more rumen undegradable protein (RUP) rich feeds or rumen-protected AA can be fed to support animal performance. The growth trajectory of biofuels has resulted in dramatic increases in the production of feeds like heat treated soybean meal (HTSBM). While the chemical composition of this product is understood, there is a need to better understand how HTSBM …

Methane Mitigation And Its Effects On Energy Utilization In Lactating Dairy Cattle, Shan C. Sherwood
Department of Animal Science: Dissertations, Theses, and Student Research
Improved methane (CH4) mitigation strategies are needed to achieve the greenhouse gas emission goals of the dairy industry. The first experiment was conducted to evaluate the effects of feeding black cumin (Nigella sativa) seed oil and acetate (BCA) on CH4 production and whole-animal energy utilization. Twelve dry Jersey cows were used in a 2-period crossover design study with 28d periods. The BCA treatment was compared to a control diet with corn oil. Both BCA and corn oil were added to the base diet as a top dress. Results from this study did not show any …

Poultry Science Faculty Publications and Presentations
The innate immune system plays an important role in the early defense against pathogens. To better understand the chicken’s innate inflammatory responses, we concurrently examined the cellular responses at the injection site and in the blood following intradermal (i.d.) injections of lipopolysaccharide (LPS) or peptidoglycan (PGN) into the pulp of growing feathers (GFs). Both LPS from Gram-negative bacteria and PGN from Gram-positive bacteria are potent stimulators of innate inflammatory responses. The time-course study conducted revealed similarly elevated levels of heterophils and macrophages in injected GF-pulps during the first 24 h for both LPS and PGN. However, PGN also stimulated rapid …

The Thai Journal of Veterinary Medicine
The purpose of this study was to determine the effect of dexmedetomidine (DEX) alone on pain mitigation following cautery disbudding in calves. A total of 21 calves were randomly divided into three groups: sham-disbudded control with placebo (S, n = 8); hot-iron disbudded after placebo (D, n = 6); hot-iron disbudded after 0.01 mg/kg of DEX (DeD, n = 7). The pain-related responses measured included serum cortisol levels, struggling scores, pain-related behaviors and other physiological values. The results indicated that the struggling scores, the cortisol concentrations from +10 to +60 min after disbudding and the area under curve of cortisol …

Poultry Science Faculty Publications and Presentations
Bacterial chondronecrosis with osteomyelitis (BCO) lameness is a bone disease characterized by the translocation of bacteria from the gastrointestinal tract, which colonize microfractures in broiler leg bones caused by rapid animal growth rate and weight gain, resulting in lameness. As such, BCO lameness represents a significant challenge for the poultry industry. This study aims to evaluate the effect of spraying broiler chicks on d0 at hatch with an Enterococcus faecium probiotic on the incidence of BCO-induced lameness, utilizing a Staphylococcus aureus challenge model. There were four treatments: (1) negative control (no probiotic + no challenge, NC); (2) positive control (no …

Chronic inflammation increases the risk of developing multiple chronic diseases, including cancer. The risk of developing colorectal cancer (CRC) specifically is increased in individuals who suffer from colitis, a characteristic of Inflammatory Bowel Disease (IBD). Diet is another risk factor for developing CRC, particularly an inflammation-promoting Western-type diet. Thus, supplementing a Western diet with functional foods containing anti-inflammatory polyphenols is a potential approach to decreasing CRC risk by reducing gut inflammation and altering gut microbiome profile. This study aimed to determine the effects of cocoa polyphenol (CP) supplementation on inflammation status and microbiome profile before, during, and after colitis when …

Background: Mesenchymal stem cells (MSCs) are increasingly trialed in cellular therapy applications in humans. They can also be applied to treat a range of diseases in animals, particularly in cattle to combat inflammatory conditions and aging-associated degenerative disorders. We sought to demonstrate the feasibility of obtaining MSCs from adipose tissue and characterizing them using established assays. Methods: Bovine adipose MSCs (BvAdMSCs) were isolated using in-house optimized tissue digestion protocols and characterized by performing a colony formation assay, cell growth assessments, cell surface marker analysis by immunocytochemistry and flow cytometry, osteogenic and adipogenic differentiation, and secretion of indoleamine 2,3-dioxygenease (IDO). Results: …

Antimicrobial Tolerance In Salmonella: Contributions To Survival And Persistence In Processing Environments, Tomi Obe, Aaron S. Kiess, Ramakrishna Nannapaneni
Poultry Science Faculty Publications and Presentations
Salmonella remains a top bacterial pathogen implicated in several food-borne outbreaks, despite the use of antimicrobials and sanitizers during production and processing. While these chemicals have been effective, Salmonella has shown the ability to survive and persist in poultry processing environments. This can be credited to its microbial ability to adapt and develop/acquire tolerance and/or resistance to different antimicrobial agents including oxidizers, acids (organic and inorganic), phenols, and surfactants. Moreover, there are several factors in processing environments that can limit the efficacy of these antimicrobials, thus allowing survival and persistence. This mini-review examines the antimicrobial activity of common disinfectants/sanitizers used …

The aims of this study were to find suitable environmental enrichment (EE) and evaluate the combined effect of two EEs, variable light intensity (VL) lighting program and EH, on mental health and hepatic metabolic regulation in commercial broilers. To find the advantageous EEs for broilers, three different EEs (board, hut, and ramp) were tested in trial 1. EEs were placed and the engagement of birds to EEs, dustbathing behavior, and daily physical activity were observed. Birds treated with huts showed higher engagement than the board- or ramp-treated birds (p < 0.05). The results of dustbathing behavior and daily physical activity indicated that the environmental hut (EH) is the most favorable enrichment for broilers. In the second trial, to test the effect of EHs on mental health and hepatic metabolic conditions, the brain and liver were sampled from the four treatment birds (20 lx_Con, 20 lx_Hut, VL_Con and VL_Hut) on day 42. The lower expression of TPH2 (tryptophan hydroxylase 2) of VL_Hut birds than those of VL_Con and 20 lx_Hut treated birds suggests the combining effect of EHs with the VL lighting program on the central serotonergic homeostasis of broilers. Reduced expressions of TH (tyrosine hydroxylase), GR (glucocorticoid receptor), BDNF (brain-derived neurotrophic factor) of VL_Hut treated birds compared to those of VL_Con and 20 lx_Hut birds suggest lower stress, stress susceptibility, and chronic social stress in VL_Hut treated birds. The expression of CPT1A (carnitine palmitoyl transferase 1) increased over three-fold in the liver of VL_Con birds compared to 20 lx_Con birds (p < 0.05). EHs treatment in VL birds (VL_Hut) significantly decreased CPT1A but not in 20 lx birds (20 lx_Hut). The expression of ACCα (acetyl-CoA carboxylase alpha) was significantly decreased in VL_Con birds compared to 20 lx_Con birds. There was no significant difference in the hepatic FBPase (fructose-1,6-bisphosphatase), GR, and 11β-HSD1 (11 β-hydroxysteroid dehydrogenease-1) expression between 20 lx_Con and VL_Con birds, but EHs significantly stimulated GR in 20 lx_Hut birds, and stimulated FBPase and 11β-HSD1 expression in the VL_Hut birds compared to 20 lx_Con birds, suggesting that the VL lighting program reduced fatty acid synthesis and increased fatty acid β-oxidation in the broilers’ liver and VL_Hut improved the hepatic de novo glucose production. Taken together, the results suggest that the stimulated voluntary activity by EHs in the light-enriched broiler house improved mental health and hepatic metabolic function of broilers and may indicate that the improved hepatic metabolic function contributes to efficient nutritional support for broilers.
Increased Coding Potential Of Bovine Herpesvirus 1, Victoria Jefferson
Increased Coding Potential Of Bovine Herpesvirus 1, Victoria Jefferson
Theses and Dissertations
Bovine respiratory disease (BRD) costs the cattle industry millions of dollars in costs in treatment and loss every year in the United States. A significant pathogen often contributes to BRD is Bovine Herpesvirus 1 (BoHV-1), a double stranded DNA virus with the ability to establish latency in the trigeminal ganglia and neurons. Primary infection with BoHV-1 results in immunosuppression that increases the risk of secondary bacterial infection and pneumonia. Because herpesviruses infect their hosts for life and can be reactivated in times of stress, BoHV-1 can present a recurring risk of BRD. The following research aims to expand the knowledge …

Browse all Datasets
Atrial Fibrillation (AF) is the most common cardiac arrythmia in adults with likely sex-specific risk factors. Female sex hormones may be important in modulating risk for atrial fibrillation. We hypothesize that pregnancy and progesterone (P4), a hormone found in high levels during pregnancy with abrupt withdrawal immediately after parturition, modulates AF susceptibility in female goats. Cardiac specific TGF-?1 transgenic female goats and age-matched wild-type (WT) female goats were utilized. Pacemakers were implanted in all animals for continuous arrhythmia monitoring and AF inducibility. AF inducibility was evaluated using 5 separate 10 s bursts of atrial pacing (160 - 200 ms). In …

Liquid Chromatography With Tandem Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Symone T. Whalin
Masters Theses & Specialist Projects
Bovine mastitis, caused by a wide array of pathogens, results in a substantial economic loss for the dairy cattle livestock industry. β-defensins are a part of the bovine’s innate immune system and act as the first line of defense against mastitis. Only foundational research has been done on β-defensins’ ability to treat and prevent mastitis. There have been no analytical methods reported in the literature for analyzing β-defensins in bovine milk. This research aims to create an analytical approach to determine β-defensins in bovine milk. It is challenging to determine an analyte in a complex sample matrix, and milk is …

The Effects Of Trace Mineral Supplementation On Performance, Health, And Carcass Quality Of At-Risk Mineral Deficient Feedlot Cattle, Tevan J. Brady
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Morbidity in feedlot cattle due to disease is a common economical loss for feedlot producers. Utah is not typically considered a ‘feedlot state’, but there are several producers in the southern part of the state that specialize in receiving at-risk cattle. These cattle are at-risk because they are coming from areas known to be mineral deficient. Areas such as the western US, are known to be deficient in several trace minerals important in immune response. Therefore, it is critical that producers have an adequate plan to decrease the negative effects that this has on economic viability of their beef operations, …
Detecting Dna Oxidation In Sperm, Alexie Zwerdling
Detecting Dna Oxidation In Sperm, Alexie Zwerdling
Student Research Symposium
Declining body-wide levels of nicotinamide adenine dinucleotide (NAD) that are present in normal aging men are linked to decreased sperm quality and DNA integrity. When NAD is low, the amount of oxidative stress on the DNA appears to be increased, due to the limited regeneration of the antioxidant glutathione, which is NAD-dependent. We therefore hypothesize that the increased sperm DNA damage in the aging male is caused by an elevated formation of 8-oxoguanine in the DNA, caused by increased oxidative stress when NAD levels are low. To test this hypothesis, a transgenic mouse model (ANDY mouse) was used to create …
Using Handmade Cloning To Reduce Oocyte Mitochondria In Reconstructed Embryos, Laura Adams
Using Handmade Cloning To Reduce Oocyte Mitochondria In Reconstructed Embryos, Laura Adams
Student Research Symposium
Mitochondrial heteroplasmy, the presence of more than one population of mitochondrial DNA (mtDNA) in one cell, can cause metabolic issues and reduced ATP synthesis, even at relatively low levels. The presence of this condition in somatic cell nuclear transfer (SCNT) embryos likely contributes to reduced prenatal and postnatal viability: the majority of the oocyte’s mitochondria is still present at the time of nuclear transfer, as well as through any further embryonic development post-fusion and activation. Though the somatic cell also contributes its mitochondria (which can successfully communicate with its nucleus), the oocyte’s mitochondria compose a greater proportion of the total …
Roles Of Nad+ In Testicular Aging And Epigenetic Sperm Modifications, Renata Hoskova
Roles Of Nad+ In Testicular Aging And Epigenetic Sperm Modifications, Renata Hoskova
Student Research Symposium
Since 1980, the average age of first-time fathers has been increasing. With increased age, sperm chromatin quality and nicotinamide adenine dinucleotide (NAD) levels are reduced. In order to condense around protamines, sperm DNA undergoes breaks, at which time epigenetic reprogramming occurs. In humans, about 2% of DNA stays wound to histones in spermatozoa. Histones carry post-translational modifications that control gene activity and have the potential to transmit epigenetic information to the offspring. Analysis of epigenetic sperm modifications is being conducted within niacin deficient versus niacin replete mice. The experimental plan includes the characterization of histone exchange in elongating spermatids via …

A large factor of climate change is its effect on infectious zoonotic diseases. Zoonotic diseases are diseases that can be transferred from animals into humans. Cases of zoonotic diseases have increased as humans have interacted more with animals, and as worldwide travel has become more frequent. It is predicted that 60% of emerging human diseases will be zoonotic. The cases will continue to increase to due climate change. As climate change continues, research has shown that new diseases will emerge from the melting permafrost and ice caps. It is also likely that pre-existing diseases will be able to migrate to …

Environmental Sampling Techniques For Herd-Level Surveillance Of Bovine Viral Diarrhea Virus, Jaden Carlson
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Control of Bovine Viral Diarrhea Virus (BVDV) relies on resource-intensive individual animal sampling to detect and remove persistently infected (PI) cattle. Herd-level surveillance tools would be useful for herds with unknown BVDV status and for monitoring herds with BVDV-free status. The overall objective of this thesis is to explore the viability of BVDV surveillance at a herd-level using samples collected without handling individual animals. The first objective was to determine the feasibility of using stable flies as a sampling tool to detect BVDV. The second objective was to determine the feasibility of using drinking water to detect BVDV. To accomplish …

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 …

Undergraduate Honors Capstone Projects
Osteoarthritis is a degenerative joint disease which plagues many older animals and humans. It is a disease that is characterized by the degeneration of joint cartilage, inflammation, as well as chronic pain and stiffness that results from this disorder. Unfortunately, most of the treatments for this painful and chronic disease mostly involve pain management and temporary relief strategies. These strategies usually include pain medication, non-steroidal anti-inflammatory drugs, injectable lubricants, as well as surgical techniques. However, because these treatments are just temporary fixes meant for pain management and to improve quality of life they must continue throughout the remainder of the …

Young Germ Cell Depleted Ovaries In Post-Reproductive Mice And Its Effects On Immune Function, Mckenna Walters
Undergraduate Honors Capstone Projects
It has previously been shown that young, cycling ovarian transplantation in aged female mice increased the general health and life span in regard to their post-reproductive health. It has further been hypothesized that this enhancement of health is directly influenced by the ovarian somatic cells. To address this hypothesis, transplants of young germ cell depleted and germ cell containing ovaries were performed on female mice. The purpose of this study is to continue to discern the reproductive influence on aging health, specifically in the area of immunological well-being. Control group mice were separated by age and treatment mice were subsequently …

Zika virus (ZIKV) causes no-to-mild symptoms or severe neurological disorders. To investigate the importance of viral and host genetic variations in determining ZIKV infection outcomes, we created three full-length infectious cDNA clones as bacterial artificial chromosomes for each of three spatiotemporally distinct and genetically divergent ZIKVs: MR-766 (Uganda, 1947), P6-740 (Malaysia, 1966), and PRVABC-59 (Puerto Rico, 2015). Using the three molecularly cloned ZIKVs, together with 13 ZIKV region-specific polyclonal antibodies covering nearly the entire viral protein-coding region, we made three conceptual advances: (i) We created a comprehensive genome-wide portrait of ZIKV gene products and their related species, with several previously …

Assisted reproductive technologies (ARTs) have now been extensively used to promote reproductive efficiency as a fertility treatment not only in human medicine but also animal reproduction. ARTs serve as an important tool to advance the fundamental knowledge of reproductive processes. The quality of female’s eggs defines its ability to undergo maturation, fertilization, and development. This quality is determined by various factors and is crucial for the success of ARTs. Any alternations happening during the egg growth and maturation process can result in the decreased quality, which could have long-lasting effects on development. Improving the developmental efficiency of the egg is …

Zika virus (ZIKV) infection of pregnant women is associated with pathologic complications of fetal development. Here, we infect pregnant rhesus macaques (Macaca mulatta) with a minimally passaged ZIKV isolate from Rio de Janeiro, where a high rate of fetal development complications was observed. The infection of pregnant macaques with this virus results in maternal viremia, virus crossing into the amniotic fluid (AF), and in utero fetal deaths. We also treated three additional ZIKV-infected pregnant macaques with a cocktail of ZIKV-neutralizing human monoclonal antibodies (nmAbs) at peak viremia. While the nmAbs can be effective in clearing the virus from …
