Summer Grazing Options, S. Ray Smith, Krista Lea

Kentucky Grazing Conference

During the last 15 years there have been several new forage species that have emerged as useful in grazing systems and many new varieties have been released of traditional species. There are many sources of information on summer grazing options. We especially encourage you to read the publication written by Dr. Garry Lacefield and colleagues, “Extending Grazing and Reducing Stored Feed Needs” (AGR-199, www.uky.edu/Ag/Forage/agr199.pdf). I have used information from this publication and other publications from the University of Kentucky Forage Website (www.uky.edu/Ag/Forage) in writing this article.

Forage Legumes: Their Importance And Management In Profitable Livestock Systems, Ben M. Goff

Kentucky Grazing Conference

The landscape of most Kentucky operations is heavily dominated by the utilization of cool-season grasses as the primary source of forage for livestock. However, legumes species, such alfalfa and red or white clovers are an essential component to a complete forage-livestock system. Relative to grasses alone, incorporating legumes into a mixture has the benefits of improving the nutritive value of the available forage in the field, extending the grazing season by increasing the yield of forage during the early summer months, and providing a more economical source of N compared to commercial fertilizers. This paper will briefly describe each of …

Maximizing Stocker Gains On Pastures, Jeff Lehmkuhler

Kentucky Grazing Conference

Stocker enterprises by definition utilize pasture forages to add weight to light weight feeder cattle. These operations add value to calves by assimilating small groups of calves and combining them into larger uniform packages. Stocker operators also enhance quality through livestock husbandry practices that “upgrade” feeders which could include castrating bulls, dehorning, improving immunity and other attributes. In an effort to optimize profit margins, stocker operators must manage feeders to ensure high rates of gain while finding a balance in stocking rates that provide adequate gains per acre.

Optimization Of Switch Virtual Keyboard By Using Computational Modelling, Xiao Zhang

Open Access Theses

In this thesis, I first reviewed some keyboard technologies used by people with motor difficulties, and described design elements that influence efficiency. I cast the design of a switch keyboard as an optimization problem, and arrangement of keys on such a keyboard as a Mixed Integer Programming problem. One significant variable in the MIP problem, the error rate, is related to several other variables. I treated modeling of the error rate as a parameter estimation problem, and used a data mining method. I designed HCI experiments to gather data for parameter estimation, using Bayesian logistic regression model. The empirical data …

Profit-Maximizing Responses To Climate Change In Commodity Agriculture: Does Adaptation Matter?, Sajeev Erangu Purath Mohankumar

Open Access Theses

Accumulation of greenhouse gases in the atmosphere has led to rising temperatures, and is expected to lead to a change in climate. Crop yields are vulnerable to these changes. Adaptation is expected to be key to combating climate change impacts, but the effectiveness of adaptation strategies is not well understood. Hence, there is a need to assess the impacts of climate change on agriculture and devise profitable adaptation strategies to combat its effects. This study uses historical and three projected climate data sets to simulate yields using the crop model Daycent, empirical relationships between weather and agronomic variables that influence …

Energy Production, Distribution, And Pollution Controls: Combining Engineering And Economic Analysis To Enhance Efficiency And Policy Design, David F. Perkis

Open Access Dissertations

Three published articles are presented which focus on enhancing various aspects of the energy supply chain. While each paper adopts a different methodology, all three combine engineering data and/or techniques with economic analysis to improve efficiency or policy design within energy markets. ^ The first paper combines a chemical engineering plant design model with an economic assessment of product enhancements within an ethanol production facility. While a new chemical process is shown to achieve greater ethanol yields, the animal feed by-products are denatured and decrease in value due to the degradation of a key nutritional amino acid. Overall, yield increases …

Soil Quality And Nitrogen Cycling Dynamics Altered By Fertility Amendments In Intensively Managed Vegetable Production Systems, Matt A. Rudisill

Open Access Dissertations

Fresh market vegetable production in the Midwest U.S. is growing rapidly as a result of increased demand for locally-sourced food. High tunnels are becoming increasingly popular among Midwest vegetable growers as these structures offer many production benefits including season extension. However, vegetables require substantial fertility inputs, particularly nitrogen (N), in order to meet desired levels of productivity, and some fertility management strategies can negatively impact soil and environmental quality. This can be particularly problematic in high tunnels, where longer production periods and modification of the growing environment put these systems at greater risk for soil degradation. Identification of fertility practices …

Microclimate Modification And Insect Pest Exclusion Using Agronet Improve Pod Yield And Quality Of French Bean, Elisha Otieno Gogo, Mwanarusi Saidi, Jacob Mugwa Ochieng, Thibaud Martin, Vance Baird, Mathieu Ngouajio

All Peer-Reviewed Publications

French bean [Phaseolus vulgaris (L.)] is among the leading export vegetable in Africa, mostly produced by small-scale farmers. Unfavorable environmental conditions and heavy infestations by insect pests are among the major constraints limiting production of the crop. Most French bean producers grow their crop in open fields outdoors subject to harsh environmental conditions and repeatedly spray insecticides in a bid to realize high yield. This has led to rejection of some of the produce at the export market as a result of stringent limits on maximum residue levels. Two trials were conducted at the Horticulture Research and Teaching Field, Egerton …

Predation Thresholds In Marine Microbial Communities Applied To Environments With Low Prey Abundances, Bonnie Bailey

OES Theses and Dissertations

Prokaryotes (Bacteria and Archaea) comprise the largest component of biomass in the world's oceans. Their abundances are controlled by resource availability, viral infections and protist grazing. Many pico- and nano-eukaryotic predators grow almost as quickly as their prey, and greatly increase in numbers as soon as their prey do, leading in tum to depletion in prokaryotes. It is still unclear however, as to what extent microbial predators are able to feed in low prey environments, most prominently in the largest biome on Earth, the deep sea (below l 000 m depth). It has been hypothesized that in low prey environments, …
