Northwest Arkansas Consumer Perceptions Of Poultry Production, Stuart Estes

Agricultural Education, Communications and Technology Undergraduate Honors Theses

Poultry production holds an important place in Arkansas economically and as a food source. The importance of poultry production ultimately hinges on the demands of the consumers and the perceptions that drive their purchases. With this in mind, this study surveyed consumers to assess their perceptions of poultry production in Arkansas. The instrument used to survey consumers was created by the researcher and an expert committee at the University of Arkansas. Consumers were interviewed through direct communication at grocery stores in northwest Arkansas. Data gathered from the study were analyzed for descriptive and correlational statistics. Data showed that consumers were …

Evaluating Economic Impacts Of Switchgrass Harvest Time, Nathanial Elsworth Cahill

Graduate Theses and Dissertations

This thesis deals with cost of production for cellulosic energy crops of switchgrass, miscanthus, and energy sorghum. The first chapter explains the rationale for development of decision support software called Energy Crop Analysis & Planning (ENCAP) and Switchgrass Harvest Date, Yield, Nutrient Removal Estimator (SHYNE). The second chapter examines harvest date implications on yield, nutrient removal, opportunity cost of modified sale dates, and post-harvest storage losses. This harvest date analysis leads to a profit maximizing harvest date from the perspective of the producer. While this harvest date may be optimal for the producer, biorefineries may be interested in sourcing switchgrass …

Effect Of Vacuum Tumbling Time, Salt Level, And Phosphate Alternatives On Processing Characteristics Of Natural Deli-Style Turkey Breast, Derek J. Schroeder

Department of Animal Science: Dissertations, Theses, and Student Research

Three studies were conducted to determine the effect of vacuum tumbling time on the processing characteristics of reduced sodium natural deli-style turkey breast. Production of sodium reduced natural deli-style turkey breast without phosphate is lower (P <  0.05) in texture and processing properties than deli-style turkey breast produced with phosphate. Reducing salt concentration to 1.0% produces natural deli-style turkey breast with less acceptable (P <  0.05) texture and processing characteristics compared to 1.5% or 2.0% added salt. Preblending was used to improve texture characteristics in reduced salt products. Control treatments had improved (P <  0.05) texture properties, decreased color values, …

Effects Of Maternal Nutrition And Post-Weaning Management In A Late Spring Calving System And Synchronization Of Estrus Using Fixed Time Ai Protocols, John D. Harms

Department of Animal Science: Dissertations, Theses, and Student Research

Three experiments were conducted to determine the impact of development systems, maternal protein supplementation, and estrus synchronization systems on beef cattle. Experiment 1 evaluated the effects of winter supplementation on cow performance and the effects of post-weaning management on progeny. Late spring calving cows grazed dormant range or meadow over winter and received either supplementation or no supplementation. Steer and heifer progeny were weaned and placed on dormant meadow or fed hay ad libitum. One half of the steers were placed in the feedlot at the end of treatment and the other half grazed range over summer. Cow winter treatment …

Remote Estimation Of Nitrogen And Chlorophyll Contents In Maize At Leaf And Canopy Levels, Michael Schlemmer, Anatoly A. Gitelson, James S. Schepers, Richard B. Ferguson, Y. Peng, J. Shanahan, Donald Rundquist

Department of Agronomy and Horticulture: Faculty Publications

Leaf and canopy nitrogen (N) status relates strongly to leaf and canopy chlorophyll (Chl) content. Remote sensing is a tool that has the potential to assess N content at leaf, plant, field, regional and global scales. In this study, remote sensing techniques were applied to estimate N and Chl contents of irrigated maize (Zea mays L.) fertilized at five N rates. Leaf N and Chl contents were determined using the red-edge chlorophyll index with R2 of 0.74 and 0.94, respectively. Results showed that at the canopy level, Chl and N contents can be accurately retrieved using green and red-edge Chl …

Optimal Copper Supply Is Required For Normal Plant Iron Deficiency Responses, Brian M. Waters, Laura C. Armbrust

Department of Agronomy and Horticulture: Faculty Publications

Iron (Fe) and copper (Cu) homeostasis are tightly linked across biology. Understanding crosstalk between Fe and Cu nutrition could lead to strategies for improved growth on soils with low or excess metals, with implications for agriculture and phytoremediation. Here, we show that Cu and Fe nutrition interact to increase or decrease Fe and/or Cu accumulation in leaves and Fe uptake processes. Leaf Cu concentration increased under low Fe supply, while high Cu lowered leaf Fe concentration. Ferric reductase activity, an indicator of Fe demand, was inhibited at insufficient or high Cu supply. Surprisingly, plants grown without Fe were more susceptible …

Improving The Efficiency Of Fall Applied N With Cover Crops, Corey Lacey

Theses and Dissertations

Nitrate loss studies in Midwestern tile-drained fields have found that fall applied nitrogen (N) resulted in elevated nitrate concentrations in tile water during both the corn and soybean year of a 2 year rotation. The effectiveness of cover crops to reduce nitrate leaching when N is spring applied has been well demonstrated, however there is a dearth of knowledge on the ability of cover crops to reduce nitrate leaching in a system where N is fall applied. Thus, the objectives of this research were to (i) investigate the efficacy of winter cover crops to reduce nitrate leaching from fall applied …

The Role Of Soil Microorganisms In The Resistance Of Giant Ragweed, Horseweed, And Common Lambsquarters To Glyphosate, Jessica Renee Schafer-Bugg

Open Access Dissertations

Continuous glyphosate use has contributed to an increasing number of problematic glyphosate-resistant (GR) weeds. The mechanism of resistance in many GR weeds is poorly understood, in part, due to a poor understanding of how exactly glyphosate kills a plant. In previous research, the efficacy of glyphosate was demonstrated to be strongly influenced by root invading soil-borne microorganisms. However, this interaction among plants, glyphosate, and soil microorganisms has only been studied in a number of crop plants, but not in weed species. This is surprising since the soil biotic environment has a strong impact on the activity of this important herbicide. …

Management Of Potato Leafhopper And Maple Spider Mite On Nursery Grown Maples, Julia Prado Beltran

Open Access Dissertations

Potato leafhopper Empoasca fabae (Harris) (Homoptera: Cicadellidae) and maple spider mite Oligonychus aceris (Shimer) (Acarina: Tetranychidae) are important pests of maple trees. Investigations determined how insecticide use and fertilization impacted the abundance of E. fabae and O. aceris on `Red Sunset' red maple and `Autumn Blaze' Freeman maples. Bifenthrin applications directed against leafhoppers reduced damage to both cultivars, but increased O. aceris on Autumn Blaze. Using a threshold of one leafhopper per branch to trigger pesticide applications protected Red Sunset maples from leafhopper injury. It also prevented outbreaks of O. aceris on Autumn Blaze because few trees reached this density. …

Pasture Condition Guide For The Kimberley, Kathryn Ryan, Elizabeth Tierney, Paul Novelly, Robert Mccartney

Bulletins 4000 -

This interactive guide has been produced as a tool for assessing pasture condition over a range of pasture types in the Kimberley. A pasture type is a distinctive mix of plant species, soil type and landscape position. For example, the Mitchell Grass Alluvial Plain Pasture type is a mixture of Mitchell grasses and other species occurring on black soil alluvial plains. Pasture condition is an important factor affecting the potential of the rangelands for animal production and is a useful indicator for the sustainability of production.

2012 Kentucky Equine Survey, College Of Agriculture, Food And Environment, University Of Kentucky, Kentucky Agricultural Development Fund, Kentucky Horse Council, Ag Equine Programs, University Of Kentucky

Kentucky Equine Survey

The last thorough equine inventory in Kentucky was undertaken in 1977, leaving the state’s equine industry with 35 years of changes, growth and con­traction that were neither measured nor analyzed.

In response to these needs, in 2011, the University of Kentucky and the Kentucky Horse Council, with support by industry organizations spearheaded by the Kentucky Quarter Horse Association, the Kentucky Thoroughbred Farm Managers’ Club and Kentucky Thoroughbred Association/Kentucky Thoroughbred Owners and Breeders, and initial support from the University of Louisville, succeeded in securing fund­ing for a large-scale, comprehensive equine survey upon which future industry plans could be built. This was …

Report Card On Sustainable Natural Resource Use In Agriculture, Robert Summers, David Weaver

All other publications

Condition and trend Nutrients, such as phosphorus (P), are essential for profitable agriculture in the south-west of WA; however, excess P – more than is required for optimal production – is stored in many agricultural soils. On average, pasture soils and arable soils contain 1.3 times and 1.6 times respectively, as much P as is required for optimal production. Production in P-enriched soils is more likely to be constrained by soil acidity (50–60% of pasture and arable soils), potassium (K) (50% of pasture soils and less than 10% of arable soils), and sulphur (S) (30% of pasture soils). Management implications …

Amino Acid Supply And Utilization With Emphasis On Lysine And Impacts On Lactation Responses Of Dairy Cows Fed Rations Containing Distillers’ Dried Grains With Solubles, Henry Paz

Department of Animal Science: Dissertations, Theses, and Student Research

Inclusion of feed coproducts in dairy diets is a common strategy used to reduce the cost of producing milk. The corn ethanol industry produces a coproduct namely distillers dried grains with solubles (DDGS) which could be of high value to the dairy industry because of its high concentration of protein and energy. Under the feeding regimes in the U.S., Lys and Met are recognized as the two most limiting amino acids (AA) for milk protein synthesis. Similar to corn, DDGS is limiting in Lys but not Met. Thus, high inclusions of DDGS have not been favored in the field as …

Fungal Foam Tested Against Avocado Threat, Jan Suszkiw

Agricultural Research Magazine

Avocados aren’t just nutritional powerhouses; they’re also the chief ingredient in such party favorites as guacamole dip.

More than 99 percent of the nation’s $322 million avocado crop is grown in south Florida and southern California (less than 1 percent is produced in Hawaii), which makes recent infestations of groves there by invasive, wood-boring ambrosia beetles so alarming. A host of counter strategies are in the works, including a biobased foam originally developed by Agricultural Research Service scientists for use against Formosan subterranean termites.

In Miami-Dade County, Florida, avocado growers are contending with Xyleborus glabratus, the redbay ambrosia beetle. …

New Strategies To Thwart Pecan Scab, Sharon Durham

Agricultural Research Magazine

Pecans are great for eating out of the shell or in a myriad of recipes. But abundant pickings of high-quality nuts are only possible if the tree escapes the devastating disease called “pecan scab.” Caused by the fungus Fusicladium effusum, it is the most destructive disease of pecan in the southeastern United States. When scab is severe, most often when rainfall is above average, nut size is reduced, and total crop loss might occur.

Scientists at the Southeastern Fruit and Tree Nut Research Laboratory in Byron, Georgia, are working to help pecan growers mitigate the effect of pecan scab. …
