An Exploration Of The Role Of Farm Business Decisions In Addressing Financial Challenges For Missouri's Beginning Farmers, Lucas Paloschi
An Exploration Of The Role Of Farm Business Decisions In Addressing Financial Challenges For Missouri's Beginning Farmers, Lucas Paloschi
MSU Graduate Theses
The next generation of farmers takes an important role in the food production for subsequent years. The American Farm Bureau Federation’s (2017) estimation that 70% increase of production will need to be achieved within the next 30 years set awareness across the globe. Researchers have been studying and trying to find means to aid beginning farmers in a variety of ways. This study measures farm decisions that affect financial performance of farmers aiming to facilitate beginning producers’ decision making. Three regressions were used to analyze how different variables affect farmers’ profitability and repayment capacity. Using a county-level data for the …
Effects Of "Lemongrass Factor" On Galleria Mellonella Hemocytes, Jennifer C. Rice
Effects Of "Lemongrass Factor" On Galleria Mellonella Hemocytes, Jennifer C. Rice
MSU Graduate Theses
The use of conventional chemical insecticides to control agricultural pest has become problematic as they may have a negative impact towards human health and the environment, resulting in a need to research alternative methods to insect pest control. Plant derived substances like essential oils have been used for generations as toxicants, repellants, and anti-feedants to control agricultural pest. More research is needed to understand how insect immune systems react to essential oils and if cellular immune responses of phagocytosis, encapsulation, and nodulation can be inhibited by such. Subjecting Galleria mellonella to various concentrations of “lemongrass factor” lets the researcher/scientist know …
Is There Room In The United States Diet For Goat Meat? Analysis Of The 2019 National Goat Meat Survey, Everett Marcus Martin
Is There Room In The United States Diet For Goat Meat? Analysis Of The 2019 National Goat Meat Survey, Everett Marcus Martin
MSU Graduate Theses
Demand for goat meat has steadily increased in the past decade, but few studies have been conducted addressing goat meat attributes and demographic factors on consumers’ willingness to buy goat meat products. Analyzing a national consumer survey on goat meat preference, a logit modeling is used addressing factors affecting willingness to buy three goat meat products: grass-fed, locally grown, and organically raised. Results indicate that quality and freshness attribute characteristics significantly affect consumer willingness to buy grass-fed, organic, and locally grown goat meat.
The Determinants Of Food Insecurity In The United States: A State Level Analysis, Zhuoya Li
The Determinants Of Food Insecurity In The United States: A State Level Analysis, Zhuoya Li
MSU Graduate Theses
The purpose of this study was to examine the determinants of food insecurity at the state level with the goal of providing policy guidance to reduce the prevalence of food insecurity in the United States. Data for the study was collected from various governmental and non-governmental sources. Linear regression models and sensitivity analyses were conducted. The study found that increase in household income is likely to significantly reduce the prevalence of food insecurity and very low food security. While poverty alleviation is more important than level of education for food insecure households, level of education is more important than poverty …
Marker-Assisted Selection To Determine The Introgression Of Rpv-3 Mediated Downy Mildew Resistance In 'Chambourcin' X 'Caberenet Sauvignon' Grapevine Population, Kavya Sri Tummala
Marker-Assisted Selection To Determine The Introgression Of Rpv-3 Mediated Downy Mildew Resistance In 'Chambourcin' X 'Caberenet Sauvignon' Grapevine Population, Kavya Sri Tummala
MSU Graduate Theses
Downy mildew caused by the fungus, Plasmopara viticola in the grapes is one of the major diseases affecting crop yield throughout the world. Breeding grapes via conventional methods for the downy mildew resistance will take approximately 25-30 years to fully evaluate and release new cultivars. Because of the long breeding cycle in woody plant species like grape, developing DNA markers linked to genes or quantitative trait loci (QTLs) for horticultural traits can greatly accelerate the breeding process and allow a much more accurate selection of progeny. This study aims to determine the presence of resistance in the 267 F1 genotypes …
Identification Of Qtls For Berry Acids And Sugar In A Vitis Aestivalis-Derived 'Norton'-Based Population, Karlene Louise Negus
Identification Of Qtls For Berry Acids And Sugar In A Vitis Aestivalis-Derived 'Norton'-Based Population, Karlene Louise Negus
MSU Graduate Theses
Acidity and sugar content are among the grape berry quality traits that influence wine quality. Despite advantageous environmental tolerances of Vitis aestivalis-derived ‘Norton’, its acid and sugar concentrations often deviate from expectations set for V. vinifera. Identification of the genetic determinants of malic acid, tartaric acid, pH, and total soluble solids (TSS) can assist in the improvement of new hybrid cultivars. For this purpose, a ‘Norton’ and V. vinifera ‘Cabernet Sauvignon’ hybrid mapping population containing 223 individuals was used to construct a linkage map containing 384 simple sequence repeat (SSR) and 2084 genotyping-by-sequencing (GBS)-derived single nucleotide polymorphism (SNP) …
Estancia Vs. Kentucky 31: Examining Leaf Nutrient Content Of Established Tall Fescue, Macie W. Clark
Estancia Vs. Kentucky 31: Examining Leaf Nutrient Content Of Established Tall Fescue, Macie W. Clark
MSU Graduate Theses
In 2020 Missouri ranked third in beef cattle production and second in hay production. As part of the fescue belt of the United States, Missouri’s agricultural industries rely on tall fescue (Lolium arundinaceum Schreb.) as a main forage crop. Two major disorders in cattle grazing tall fescue are fescue toxicosis and grass tetany. Fescue toxicosis occurs when animals consume toxic ergot alkaloids produced by an endophyte within the tall fescue plants. The most commonly grown tall fescue variety, Kentucky 31, is infected with the toxic endophyte. Varieties containing a novel non-toxic endophyte, such as Estancia, have been developed to …
Establishing Agroforestry Silvopasture Systems In The Missouri Ozark Region, Kara Lynn Powelson
Establishing Agroforestry Silvopasture Systems In The Missouri Ozark Region, Kara Lynn Powelson
MSU Graduate Theses
The Missouri Ozarks is located in the south-central part of Missouri, ranging from the very southwest corner of the state and east to St. Louis. This region is enriched with large dense populations of oak and hickory tree species, while also being occupied with prime forage pastures for livestock grazing. Missouri is ranked second in the nation for farming operations and hay production, while also third in the nation for beef cow number of head (MDA 2021). The objective of this study is to observe the establishment of two separate silvopasture systems: a planted walnut plantation and a converted silvopasture. …
In Vitro Digestibility Of Forages Incubated With Equine Fecal Inoculum Stored Under Varying Conditions, Shianne K. Walther
In Vitro Digestibility Of Forages Incubated With Equine Fecal Inoculum Stored Under Varying Conditions, Shianne K. Walther
MSU Graduate Theses
This study evaluated the in vitro effect on digestibility of forages when incubated with microbial inoculum formed from equine feces stored under varying conditions. Fecal material was stored at four storage conditions of 12˚C for 6 hours, 12˚C for 12 hours, 23˚C for 6 hours and 23˚C for 12 hours under aerobic conditions. Stored fecal material was used to form microbial inoculum for use in an ANKOM Daisy II Incubator. Nine different forage samples were digested in the ANKOM Daisy II Incubator to evaluate interactions between storage condition of microbial inoculum and chemical composition of digested forage samples. Forage samples …
