Applying deep learning technologies to discovery and characterization of genetic variants in animal genomes
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] The scale of publicly available genomic data has rapidly expanded by an order of magnitude within the last decade. However, research with these aggregated public data requires minimizing the ... -
Discovery and phenotyping of the determinants and receptors of post-fertilization sperm mitophagy
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] This thesis is concerned with two important aspects of sperm physiology -- mitochondrial health prior to fertilization and mitochondrial inheritance after fertilization. The factors and mechanisms ... -
Effects of long-term postgastric infusion of casein or glutamic acid on small intestinal starch digestion, energy balance, body composition, and metabolic fates of luminally assimilated glucose carbon in cattle
(University of Missouri--Columbia, 2022)Small intestinal starch digestion (SISD) in ruminants is limited, but SISD can be improved by postruminal supply of casein or glutamic acid. There are no reports on the effects of increases in SISD in response to greater ... -
Effects of supplemental amino acid and grain processing on nutrient disappearance and nitrogen and energy balance in cattle
(University of Missouri--Columbia, 2023)Milk and meat production among cattle fed corn and corn products is often limited by available energy and amino acids absorbed from the diet. Nutrients available from feed to support lactation or growth are a result of ... -
An examination of influenza immunity in pigs and their role in assessing antiviral therapies for humans
(University of Missouri--Columbia, 2022)The lung is dynamic barrier organ with a complex cell population. Pulmonary immune cells must balance an effective and tolerogenic response to keep homeostasis. Due to numerous similarities to the human respiratory system, ... -
Food nutrients required for maintenance of brood sows and for growth of pigs to weaning time
(University of Missouri--Columbia, 1910)A great many experiments have been carried on with swine, which have determined the amount of feed necessary and the cost to produce a pound of gain during periods of fattening, with various kinds and combinations of ... -
Host immune response to a bacterial toxin at single-nuclei resolution in the chicken
(University of Missouri--Columbia, 2023)Understanding the intricate dynamics of the host immune response to a bacterial pathogen, including both the innate and adaptive systems, to a bacterial pathogen is crucial for improving our knowledge of avian immunology, ... -
Improving the value of pigs with severe combined immunodeficiency through novel transplantation
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] Continual rapid advances in biomedical research necessitate the efficient development of animal models that translate findings from preclinical studies into the clinics. Traditional animal models ... -
Investigating sire fertility : the relationship between spermatozoa characteristics and early embryonic development
(University of Missouri--Columbia, 2022)Early embryonic mortality in cattle occurs between days 1-27 of gestation and is one of the primary contributors to economic failure in the dairy industry. Specifically, by day 7 of gestation, up to 50 percent of all embryo ... -
Involvement of aberrant chromosome architecture and locus-specific vulnerability to DNA methylation epimutations in bovine large offspring syndrome
(University of Missouri--Columbia, 2022)Large/abnormal offspring syndrome (LOS/AOS) and Beckwith-Wiedemann syndrome (BWS) are similar congenital overgrowth syndromes which occur naturally in ruminants and humans, respectively. The incidence of these syndromes ... -
Mapping copy number variants across the cattle genome
(University of Missouri--Columbia, 2023)Copy number variation across individuals is known to be associated with traits such as gene expression, disease resistance, and other phenotypic variations. Due to improvements in accurately detecting genotypic variation ... -
Modulation of bovine preimplantation embryonic development and pregnancy by FGF2, LIF, and IGF1
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] In vitro embryo production enhances genetic selection through capitalizing on superior genetics, improving fertility, and increasing animal efficiency, all of which contribute to sustainable ... -
The role of mitochondria in early-onset preeclampsia
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] Placental mitochondrial dysfunction may play a role in the etiology of early-onset preeclampsia (EOPE). Mitochondrial function is impaired at term in placentas delivered from EOPE pregnancies, ... -
A systems approach to deriving carcass value from Holstein x SimAngus cattle in an accelerated finishing model
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] Beef x dairy has increased in popularity, altering the U.S fed beef supply. The objective of this dissertation was to evaluate the effect of Holstein x SimAngus (Hol x SimAngus) breeding and ... -
Tracing cat domestication through population genetics and capturing genotype-by environment interactions in US beef cattle genomic predictions
(University of Missouri--Columbia, 2022)Cat domestication initiated as a symbiotic relationship between wildcats and the peoples of developing agrarian societies in the Fertile Crescent. To refine the sites of cat domestication, over 1,000 random-bred cats of ...
