A Disaggregated Analysis Of Beef Import Demand In Japan, Christina D. Greer 2022 University of Tennessee, Knoxville

A Disaggregated Analysis Of Beef Import Demand In Japan, Christina D. Greer

Masters Theses

Japan is an important partner for the U.S. beef industry and a major beef importing country. In 2020, Japan was the world’s third-largest importer of beef products (USDA, 2021). Although the Japanese beef market has been studied, research on the importance of product characteristics in determining import demand has been limited. The goal of this research is to provide a detailed analysis of how U.S. beef products compete in the Japanese market relative to other exporting countries based on prices, product form (chilled versus frozen), and product characteristics (boneless versus bone-in).

This study will focus on three ...

2020 Northeast Maple Business Benchmark, Mark Cannella, Christopher Lindgren

UVM Extension Faculty Publications

The 2020 production season began just as the Covid-19 pandemic was emerging across the United States. Most states quickly enacted “essential industry” provisions that enabled agricultural and forestry operations to remain active assuming their workers were healthy and willing to report to work. Lingering policy and regulatory issues faced maple producers in the coming months as the pandemic disruptions continued. While many businesses faced short term cash flow challenges the overall maple demand rebounded and exceeded expectations for growth by the end of 2020.

The 2020 Northeast Maple Business Benchmark report documents the eight year of financial record analysis for ...

Thlaspi arvense (field pennycress) is being domesticated as a winter annual oilseed crop capable of improving ecosystems and intensifying agricultural productivity without increasing land use. It is a selfing diploid with a short life cycle and is amenable to genetic manipulations, making it an accessible field-based model species for genetics and epigenetics. The availability of a high-quality reference genome is vital for understanding pennycress physiology and for clarifying its evolutionary history within the Brassicaceae. Here, we present a chromosome-level genome assembly of var. MN106-Ref with improved gene annotation and use it to investigate gene structure differences between two accessions (MN108 ...


Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition; A Brief Exploration And Application Of Extension Principles, Micah Most 2022 University of Nebraska-Lincoln

Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition; A Brief Exploration And Application Of Extension Principles, Micah Most

Theses and Dissertations in Animal Science

The objective of our first study was to determine how administering anti-inflammatory dexamethasone and ω-3 polyunsaturated fatty acid (PUFA)-rich fish oil affects growth efficiency and body composition in heat-stressed finishing lambs. Commercial wethers were randomly assigned to be fed under heat stress (35°-40℃) or thermoneutral (19℃, n = 10) conditions for 30 d, and controls were pair-fed to eliminate differential feed intake. Heat-stressed wethers were randomly assigned to receive clinical-dose dexamethasone IM injections every 72 h, twice daily fish oil capsule oral boluses, or placebos. Heat stress decreased (P < 0.05) growth and efficiency, but dexamethasone and fish oil supplementation recovered these performance measures. Heat stress also decreased (P < 0.05) predictive body composition metrics that were at least partially improved by administration of dexamethasone and fish oil. Proximate analyses of muscles showed that heat stress decreased (P < 0.05) percentage of protein and increased (P < 0.05) percentage of intramuscular fat, neither of which was improved by dexamethasone or fish oil. Immunohistochemistry revealed that heat stress decreased (P < 0.05) myoblast differentiation and muscle fiber size, but anti-inflammatory supplementation recovered differentiation only. Plasma IGF-1 concentrations were not different among groups throughout the study. These findings demonstrate how heat stress-induced inflammation contributes to impaired growth, efficiency, and body composition observed in heat-stressed feeder lambs. However, targeting inflammation with dexamethasone or fish oil recovers many of these deficits.

Oestrogenic Subterranean Clover Guide. Identification And Remediation, Kevin J. Foster, Megan H. Ryan, Daniel R. Kidd 2022 Department of Primary Industries and Regional Development, Western Australia

Oestrogenic Subterranean Clover Guide. Identification And Remediation, Kevin J. Foster, Megan H. Ryan, Daniel R. Kidd

Bulletins 4000 -

Subterranean clover (subclover, Trifolium subterraneum L.) is an annual pasture legume that provides high quality feed for livestock. It is estimated to be sown over 30 million hectares across southern Australia, with cultivars developed for the low, medium and high rainfall zones. Unfortunately, some older cultivars contain high levels of phytoestrogen which can affect the reproductive system of sheep and cause other health issues. This became a significant issue for sheep producers from the 1940s as new land was cleared and sheep grazed subclover-dominant pastures. There was a collection of livestock issues observed and these were grouped together under the ...

In this dissertation, we detail the efforts made over the past few decades to provide training to food producers and food handlers as well as recommendations that have been made for improvement based on these studies. By borrowing from more advanced fields of study ...


An Investigation Of Factors Affecting The Rooting Ability Of Hardwood Muscadine Cuttings And Genetic Diversity Of Wild And Cultivated Muscadine Grapes (Vitis Rotundifolia Michx.), Kenneth Buck 2022 University of Arkansas, Fayetteville

An Investigation Of Factors Affecting The Rooting Ability Of Hardwood Muscadine Cuttings And Genetic Diversity Of Wild And Cultivated Muscadine Grapes (Vitis Rotundifolia Michx.), Kenneth Buck

Graduate Theses and Dissertations

The muscadine (Vitis rotundifolia syn. Muscadinia rotundifolia) is a grape species native to the southeastern United States. Muscadines are one of three grape species in subgenus Muscadinia with a chromosome number of 2n=40 (V. rotundifolia, V. munsoniana, and V. popenoei), making them genetically distinct from the European wine and table grape (Vitis vinifera) and other species in subgenus Euvitis. Rooting hardwood cuttings from muscadine vines has traditionally been considered an exceptionally difficult task. Many previous studies observed almost no root formation, leading to a general consensus that muscadines should either be propagated by softwood cuttings or vegetative layering. However ...

Exploration Of Genes Controlling Grain Yield Heterosis In Hybrid Wheat (Triticum Aestivum L.) Utilizing 3ʹ Rna Sequencing, Nichole Miller

Theses, Dissertations, and Student Research in Agronomy and Horticulture

The implementation and future success of hybrid wheat (Triticum aestivum L.) is impacted by breeders’ inability to create consistent high yielding, high heterosis hybrids. This research addresses this problem by conducting an exploration of transcriptomes from hybrids and parent lines to determine what genes are active in heterotic or non-heterotic hybrids and how their level of expression can explain the phenotype of grain yield heterosis. Using hybrids that showed positive mid-parent heterosis (MPH), classified as heterotic in our study, and negative or no difference MPH hybrids, classified as non-heterotic, differentially expressed genes (DEGs) potentially related to heterosis and hybrid yield ...


Making Better Farm Management Decisions, Matt Stockton 2022 University of Nebraska - Lincoln

Making Better Farm Management Decisions, Matt Stockton

Cornhusker Economics

Traditionally, producer education efforts around farm management are directed at understanding the academic topics of business operations and management including, accounting, law, human resources, marketing, production, risk, finance, etc. The information, techniques and tools taught are often concrete and focus on measurement, analysis, and data. For instance, a traditional grain marketing education program would generally include topics in forward contracts, options, futures, hedge to arrive, basis contracts, storage, and seasonality. While these programs can be quite powerful in developing quantitative skills and knowledge, they neglect a key element needed by all farm managers to make objectively clear decisions. This key ...

Limited knowledge about how nitrogen (N) dynamics are affected by climate change, weather variability, and crop management is a major barrier to improving the productivity and environmental performance of soybean-based cropping systems. To fill this knowledge gap, we created a systems understanding of agroecosystem N dynamics and quantified the impact of controllable (management) and uncontrollable (weather, climate) factors on N fluxes and soybean yields. We performed a simulation experiment across 10 soybean production environments in the United States using the Agricultural Production Systems sIMulator (APSIM) model and future climate projections from five global circulation models. Climate change (2020–2080) increased ...
