Digestibility Estimates Based On A Grass Growth Model Are Distributed Via Internet To Finnish Farmers, Marketta Rinne, J. Nousiainen, I. Mattila, H. Nikander, P. Huhtanen

IGC Proceedings (1977-2023)

Optimising the harvesting time of grass in primary growth is difficult under Finnish climatic conditions, because the digestibility of grass decreases on average by 0.5 percentage units daily. We constructed a model based on cumulative temperature and geographical location which estimates the digestibility of grass. This model is used to produce estimates utilising real time weather information. The estimates are presented as a map, which is revised daily. Farmers have free access to the maps via Internet.

The Effect Of Batter Characteristics On Protein-Aided Control Of Fat Absorption In Deep-Fried Breaded Fish Nuggets, Lulu Cui, Jiwang Chen, Yuhuan Wang, Youling L. Xiong

Animal and Food Sciences Faculty Publications

Soy protein (SP), egg white protein (EP), and whey protein (WP) at 6% w/w were individually incorporated into the batter of a wheat starch (WS) and wheat gluten (WG) blend (11:1 w/w ratio). Moisture adsorption isotherms of WS and proteins and the viscosity, rheological behavior, and calorimetric properties of the batters were measured. Batter-breaded fish nuggets (BBFNs) were fried at 170 °C for 40 s followed by 190 °C for 30 s, and pick-up of BBFNs, thermogravimetric properties of crust, and fat absorption were determined. The moisture absorption capacity was the greatest for WS, followed by WG, SP, EP, and …

Remote Sensing Application To Grassland Monitoring, Z. B. Nan

IGC Proceedings (1977-2023)

Application of remote sensing to the management of grassland resources, the role this plays in developing sustainable grassland farming systems and opportunities for further development are outlined. Use of remote sensing technologies in grassland monitoring has a history of more than 30 years. Both fine- and coarse-grained remote sensing techniques are used to monitor and study grasslands. Fine-grained techniques are used to study landscape scale processes through the use of sensors providing spatial resolution of a few meters, whereas coarse-grained techniques are used to study catchment scale areas, and even entire biomes, using satellite-based sensors with a spatial resolution of …

Modelling Grassland Ecosystems, J. H. M. Thornley

IGC Proceedings (1977-2023)

In this contribution a view of the promise and difficulties of modelling grassland is given. This is largely centred around work with a grassland ecosystem simulator known as the Hurley Pasture Model.

A brief introduction sets forth possible reasons for building a large ecosystem model, and stresses the importance of modelling objectives. It is suggested that a model is de rigeur for any research programme which aims to take a firm grasp of the complex responses of grassland. Mechanistic models are required to provide the understanding needed for intelligent and flexible management of grassland, whatever the prevailing environmental or economic …

Grassland Management And Animal Product Quality, G. W. Sheath, J. B. Coulon, Q. A. Young

IGC Proceedings (1977-2023)

The expectations of consumers ultimately determine the specification of product quality; and grassland systems produce a wide range of animal-based products. Therefore, to provide focus, this paper deals only with food products that are destined for markets that exhibit strong discretionary choice. Quality expectations of consumers have traditionally been based on product attributes such as taste, freshness, nutritional value and appearance, but customer expectations are expanding to encompass food safety, environmental care, animal welfare and biotechnologies.

Grassland forages and their management influence the intrinsic sensory properties of food. A dairy products case study is presented, indicating that pasture species and …

Priority Setting And Funding Of Agricultural Research, M. Petit

IGC Proceedings (1977-2023)

Agricultural research funding amounts and modalities have been profoundly transformed in recent years in many countries. For instance, competitive funding has become the norm rather than the exception in most countries and funding sources have been greatly diversified. In addition, in some major countries, the private sector has become a major actor In agricultural research, both as a funder of research and as a provider research results. This poses a major challenge to public research institutions, which remain the major agricultural research actors and employers of researchers in most countries. With these changes in funding, formal procedures for research priority-setting …

Contextual Factors In The Management Of Common Grazing Lands: Lessons From Mongolia And Northwestern China, R. Mearns

IGC Proceedings (1977-2023)

Seen in a global perspective, pastoral development is now increasingly motivated by social and environmental objectives rather than by production- or output-orientated objectives. Attention is shifting towards a broader concern with sustainability, both of grasslands, and of the livelihoods of those who rely on them (de Haan et al, 1997, Fratkin and Mearns forthcoming). Quite how these twin sustainability objectives may be achieved in particular contexts, however, is an empirical question. Drawing on examples from a diverse range of natural grassland-based livestock production systems under economic transition in Mongolia and northwestern China, this summary paper aims to show how an …

De-Intensification Of Grasslands: Understanding The Processes To Find The Balance, K. C. Hodgkinson

IGC Proceedings (1977-2023)

There is a growing trend in Australia and other developed countries for deintensification of animal production from grasslands and for grasslands to be used for purposes other than livestock grazing. These shifts are occurring for a variety of reasons including unsustainable land management practices, environmental pollution, loss of conservation value, poor commodity prices and declining rural infra-structure and communities. In Australia, the shifts are under way in agricultural grasslands, where sown pastures occur in a matrix of semi-natural woodlands, but less so in the other three major natural grasslands that forms the arid and semi-arid rangelands.

The conversion of natural …

De-Intensification Of Grasslands: Current State And Trends, Michael Duru, Bernard Hubert

IGC Proceedings (1977-2023)

De-intensified use of grasslands, and more generally of the livestock systems they support, has been triggered by a growing sensitivity of citizens to environmental quality (nitrogen) and quality of animal products, and by the warnings addressed to political authorities by scientists about the environmental consequences of economic imbalances (decreasing biodiversity, drop in soil fertility, greenhouse effect), and in particular of food overproduction in Europe.

From an ecological standpoint, grassland de-intensification must be envisaged whenever the techniques implemented disrupt resource sustainability. The grassland resource itself may be at risk when a rate of vegetation offtake by herbivores that is incompatible with …

Spent Hemp As An Animal Feed And Vertical Price Transmission In Us Hemp Value-Added Supply Chain, Solomon E. Odiase

Theses and Dissertations--Agricultural Economics

This thesis comprises of two articles covering spent hemp's prospects as an animal feed and the price interaction across the hemp commodity value-added supply chain. The first article uses a comparative analysis tool to analyze the potential of spent hemp as an animal feed or feed ingredient based on its yield, nutritional composition and market price. This comparative advantage analysis revealed that spent hemp is competitive based on its rich essential nutritional content, comparatively high yield per acre, and low market price. Furthermore, with the increasing drought conditions, production cost and market price of alfalfa hay, spent hemp may fill …

An Integrated, Holistic Approach To Supporting The Wellbeing Of The Contemporary Social Services Workforce, Julia Moore

DSW Capstone Projects

Despite nearly 40 years of research regarding the effects of psychological distress among the social services workforce, there remains a lack of congruity among scholars and experts regarding the definition and epidemiology of the distinct constructs, including secondary traumatic stress, vicarious trauma, compassion fatigue, and burnout. Current literature on these phenomena indicates that a lack of empirical methods for scientifically studying outcomes regarding effective prevention and intervention strategies have stalled efforts to advance the field of secondary trauma and create practical approaches to protecting the workforce serving trauma-exposed clients. This capstone project is focused on understanding the current literature regarding …

An Examination Of Diabetes Prevention Program Translations For Eastern Kentucky, William H. Robinson

DSW Capstone Projects

This capstone project examined translations of the National Diabetes Prevention Program (DPP) that have been adapted to improve cultural competency and analyzed the potential application of these adaptations to serve communities in Eastern Kentucky. Findings in the project were synthesized using the Ecological Validity Model (EVM) posited by Bernal et al. (1995) and the RE-AIM framework developed by Glasgow et al. (1999). EVM and RE-AIM have been used in other systematic literature reviews of the DPP and provide a framework for conceptual analysis and practice application of the findings. This project recommends changes in public health policy and social work …

Elucidating The Role Of Polycomb Repressive Complex 2 In Lung Stem Cell Fate And Lung Disease, Aria Byrd

Theses and Dissertations--Toxicology and Cancer Biology

The average human lungs take ~22,000 breaths and inhale ~2,000 gallons of air each day. This organ is the primary conduit for the transfer of oxygen to the internal organs, making it crucial for the sustainment of life. Consequently, mechanical malfunction of the lungs and/or pollution of inhaled air negatively impact internal organ function and ultimately put survival in jeopardy. Epigenetics, by nature, is a plastic phenomenon in which environmental stimuli influence short term, long term, and generational gene expression patterns. Chronic exposure of harmful stimuli to the lung epithelium has also been shown to alter epigenetic pathways, engender aberrant …

“Don’T Feel Like You Have To Do This All On Your Own”: Exploring Perceived Partner Support Of Breastfeeding Among Black Women In Kentucky, Jardin Dogan

Theses and Dissertations--Educational, School, and Counseling Psychology

Background: Partner support improves breastfeeding initiation and continuation among mothers. However, few studies have explored partner support for breastfeeding among Black women living in the southeastern U.S., who report the lowest rates nationally of breastfeeding compared to women of other racial groups. Ways to increase support of Black women’s breastfeeding may be best understood from an Afrocentric perspective.

Research Aim: This qualitative study aimed to explore perceptions of partner support among Black mothers to abductively develop a culturally relevant framework of partner support to improve their rates of breastfeeding. Our research question was, “What partner support behaviors do Black …

Agri-Food Waste Reduction And Utilization: A Sustainability Perspective, Akinbode A. Adedeji

Biosystems and Agricultural Engineering Faculty Publications

As the human population edges closer to nine billion, we must explore how we can sustainably use Earth’s limited resources. Current agricultural production and food processing create significant amounts of wastes that have drastic effects on the environment, on the cost of production, and on human health and well-being. About a third of these wastes are produced domestically, as well as from agricultural production and food processing, and it often constitutes a disposal problem, although it contains many carbon-based materials (proteins, lipids, carbohydrates, micronutrients, bioactive compounds, and dietary fibers) that can be converted into useful value-added products. Converting these wastes …

Maximal Strength Training Increases Metabolic Energy Expenditure In Sedentary Adults Classified As Obese, Robert E. Anderson Iii

Theses and Dissertations--Nutrition and Food Systems

Background: Metabolic adaptations reduce resting and non-resting energy expenditure to account for approximately 120 kcal/day. Weight loss promotes greater skeletal muscle efficiency, reducing the energy cost of physical activity and is correlated with declines in skeletal muscle glucose oxidation. Maximal Strength Training (MST) has the potential to upregulate glucose utilization and may offset these metabolic adaptations. Objective: To determine if MST offsets markers of metabolic adaptation by increasing resting and non-resting energy expenditure in sedentary individuals classified as obese. Methods: Five (5) participants (2 females, 3 males), ages 18-35 years, with obesity (BMI 30–45 kg/m2) were enrolled in an 8-week …

Leveraging Community Health Workers’ Expertise In The Community To Address Food Insecurity In Appalachia, Alexis Kimbro Scott

Theses and Dissertations--Nutrition and Food Systems

Residents of the Appalachian region of Kentucky are disproportionately affected by poor social determinants of health that contribute to the persistence of food insecurity and diet related diseases in this region. Poverty levels persist in rural areas of the Appalachian region while they improve throughout the rest of the United States. As this further perpetuates food insecurity in rural Appalachia, it is critical to identify culturally sensitive solutions to food insecurity. Utilizing Community Health Workers (CHWs), lay members of the community who have deep understanding of the communities they live in and serve, may be the answer to this problem. …

Efficacy Of Prebiotic Dietary Intervention To Mitigate Risks For Dementia Via The Gut-Brain Axis, Lucille M. Yanckello

Theses and Dissertations--Pharmacology and Nutritional Sciences

Alzheimer’s disease (AD) is the most common form of dementia with various risk factors including age, environmental factors such as brain injury and genetic factors, such as the E4 allele of the Apolipoprotein gene. Presence of the APOE4 allele increases AD risk by two- to four- fold. Recent studies have shown that mild traumatic brain injury (mTBI), even without loss of consciousness, increases risk of dementia diagnosis by more than two-fold in military personnel and is also a significant environmental risk factor for developing dementia in the general population. The gut-brain axis (GBA) or bi-directional communication between the brain and …

Motivating The Protection Of Others: A Theoretical Extension And Empirical Test Of Compassion Appeals, Erin B. Hester

Theses and Dissertations--Communication

The term “wicked problems” is used to describe a constellation of social issues that are deeply entangled (Rittel & Webber, 1973). Although these social messes affect everyone in society, some people suffer more than others (Ackoff, 1974). Nevertheless, tackling wicked problems begins with recognizing our shared responsibility to ease the misfortune of others (Rittel & Webber, 1973). As such, they provide an ideal context to investigate the persuasive effectiveness of messages that encourage the protection of others (i.e., other-protection messages). Wicked problems, such as the opioid crisis and food insecurity, need strategies that compel individuals to engage in prosocial action …

Applying The Causal Network Model To Advance Care Planning Messages, Katherine Leigh Harville

Theses and Dissertations--Communication

The process of advance care planning often involves conversations that focus on worst case scenarios and discussions of end-of-life, which makes the topic a daunting one. Most of these conversations occur with older adults or individuals who are seriously ill. However, advance care planning is of importance to those who are healthy, young adults as well. Narrative messages could help simplify the process of approaching such conversations and provide tools for conducting them in a more effective manner.

The proposed study makes use of the causal network model, a model that proposes that the location of information within narratives impacts …

This study examines the changes in rumen fermentation resulting from feeding monensin/tylosin and Programmed Nutrition Beef Finisher. The goal was to determine if these shifts in rumen fermentation contribute to the Programmed Nutrition response observed in vivo. This study also analyzes how different levels of α-amylase (Amaize)supplementation impacts feedstuff degradation and utilization in vitro. In vivo experiment used eight steers in a replicated …

Consumer Measures Of Local Food System Performance And Shopping Behavior Across Covid, Azita Varziri

Theses and Dissertations--Agricultural Economics

This dissertation consists of three essays: In the first essay, we utilize a Principal Component Analysis (PCA) to measure the residents’ perceptions of the local food system performance. Local food system (LFS) components are classified into related measures that may help explain the overall performance scores provided. LFS performance measures are explored across 15 different communities in the U.S. South. The second essay explores the awareness and performance differences toward farmers markets, including the markets themselves and the corresponding local food product quality, product diversity, and markets infrastructure across different age-range groups and community sizes in Southern states. Finally, in …

The Pet’S ‘Perfect Bowl’: Environmental And Welfare Discourse In Alternative Pet Food Movements, Carly Baker

Theses and Dissertations--Geography

Marketing ‘sustainable and humane’ super-premium dog kibble has emerged alongside alternative food movements (AFM). Unfortunately, super-premium pet-food comprised of ‘high-quality’ protein is at odds with sustainability and affect for particular animals. This study analyzed social and geographical (mis)representations of nonhumans in the pet-food commodity chain by tracing how knowledge and value is produced, and mapping the geography of Open Farm dog food. I assess these geographies and discourses and I identify the following: (1) sustainability claims focus on transportation and packaging, ignoring the significant environmental and social impacts of animal agriculture. (2) Images of farmed animals on packaging often do …

Maternal Occupational Exposure To Organic Solvents And Noise: Maternal Effects And Infant Outcomes, Kristen Van Buren

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Introduction: Several maternal occupational exposures have not yet been studied for potential reproductive harm or have inconsistent findings in the literature. Despite the challenges, identification of potential risk factors, specifically reproductive toxicants, is necessary to mitigate and prevent adverse health outcomes for working mothers and their infants. The purpose of this study was to examine maternal occupational exposure to organic solvents and noise to small-for-gestational age (SGA) and preterm birth (PTB) among infants. Additionally, the study sought to examine maternal occupational exposure to noise and presence of gestational diabetes (GDM) and pregnancy-related hypertension among participant mothers.

Methods: The study population …
