Hay Quality: What Is It?, Garry D. Lacefield, Don Ball

Kentucky Alfalfa and Stored Forage Conference

Profitable livestock production almost always requires a forage program that will supply large quantities of adequate quality, homegrown feed. A major percentage of the feed units for beef (83%) and dairy cattle (61%) come from forages. In addition, forages supply an estimated 91%, 72%, 15% and 99% of the nutrients consumed by sheep and goats, horses, swine, and wildlife, respectively.

Alfalfa And The Environment, Don Ball

Kentucky Alfalfa and Stored Forage Conference

We live in a society in which many people don’t understand or appreciate agriculture as much as they really should. After all, only about 2% of the population of the United States is involved in agriculture, so most people don’t know much about it. Furthermore, most don’t spend much time thinking about it. Forage crops, including alfalfa, are especially under-appreciated because forage is not consumed directly by humans (alfalfa sprouts being a minor exception).

Red Meat, Our Health And Alfalfa--Separating Scientific Fact From Opinions, Policy, Politics, And Bureaucracy, Peter Ballerstedt

Kentucky Alfalfa and Stored Forage Conference

The general public is becoming increasingly aware of the failure of the official nutritional policy of United States and other countries. Books like Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health (Taubes, 2008), Why We Get Fat and What To Do About It (Taubes, 2011) and The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet (Teicholz, 2014) have exposed the disconnect between nutrition science and nutrition policy, and have told the story of how we’ve come to this point in history.

Grazing Alfalfa: Real Cost Of "Fear" Of Bloat, S. Ray Smith, Kenneth H. Burdine, Jeff Lehmkuhler

Kentucky Alfalfa and Stored Forage Conference

In the Southeast, including legumes like alfalfa and clover in pastures provides many advantages. It reduces the impact of fescue toxicosis, provides free nitrogen, and improves pasture quality leading to increased animal performance. Individual animal performance is greater on grass/legume pastures compared to performance on similar monoculture grass stands. Daily gains for steers grazing clover-fescue swards is improved compared to straight tall fescue pastures (Figure 1). Improved performance is partially due to greater forage intakes. This practice is sound management even though legume bloat is a risk to livestock. If one considers the number of cattle grazing pastures containing legumes …

What's Required To Break The "Beef Per Acre" Kentucky Record, Kenneth R. Johnson

Kentucky Alfalfa and Stored Forage Conference

As I approach the task that Garry assigned me, I ask the question, “Do I really want to attempt to produce 1400 or more pounds of beef per acre?” An easy answer is “yes,” but more likely “no.” Most farmers I know, full or part time have all they can do now and to reach record levels of anything requires much more time and management. I am going to attempt to discuss the steps I think that will be required to reach record breaking production. Higher gains are certainly possible. We know alfalfa can produce 8 to 10 tons of …

Alfalfa Is Our Family Farming Operation, Myron Ellis

Kentucky Alfalfa and Stored Forage Conference

Ellis Family Farm is a 5th generation family farm located in Harrodsburg, KY. Currently we farm 1250 acres total of which 870 acres is owned and the remainder is leased. We buy and resale between 1500-1800 head of feeder cattle per year and have 100 head of brood cows. The cattle operation feed is completely supplied by the first cutting of our 580 acres of alfalfa and alfalfa grass mix hay. From the second cutting on, we produce small square bales of alfalfa for the horse market in four states. Our normal production of square bales ranges between 75,000 and …

Use Of Research Aircraft Data To Validate Mesoscale Model Forecasts, Travis Swaggerty, Melanie Wetzel, Dorothea Ivanova

Aviation / Aeronautics / Aerospace International Research Conference

A NSF funded Student Training in Airborne Research and Technology (START) two-week deployment of the University of Wyoming King Air (UWKA) research aircraft was conducted at Embry-Riddle Aeronautical University (ERAU) in Prescott, Arizona during late March and early April 2014. Some of the goals of this program were to build knowledge on airborne atmospheric research for undergraduate students across multiple departments and to collect a valuable set of aircraft data for atmospheric model validation. Data collection for 10 research flights is available for mesoscale model case study validation.

This project utilizes the Weather Research and Forecasting mesoscale model (WRF), version …

Improvement In Pilot Training For Aircraft Icing Conditions, Cody Denver, Melanie A. Wetzel

Aviation / Aeronautics / Aerospace International Research Conference

One of the most dangerous atmospheric hazards in aviation is aircraft icing. Ice can build on aircraft surfaces, causing decreases in thrust and lift while increasing drag and weight. These effects can be detrimental to any aircraft's ability to successfully remain in flight. Improvement in pilot knowledge of and response to icing conditions can be attained through use of specific meteorological forecast products, completion of interactive training modules, and understanding of cloud physical processes gained through the analysis of aircraft measurement case studies. This poster presents a strategy for enhancing the training of professional pilots in meteorological conditions which cause …

Microcontrollers In The Aviation Classroom, Padraig Houlahan

Aviation / Aeronautics / Aerospace International Research Conference

Modern commercial aircraft are increasingly dependent on digital technologies that detect sensor data and pilot control movements, interpret them, and then issue appropriate control signals to remote motors that move control surfaces. Because such technologies are innately complex, it would appear there is an unacceptably large academic burden on introducing them into the undergraduate pilot's curriculum .

However, in recent years there has been an explosion of interest in using micro-controllers in academic teaching (high-school and undergraduate levels) and in hobby applications, resulting in a large, online, freely available knowledgebase of techniques and solutions. Here, I demonstrate how easy it …

Aviation Security Impacts Of Meteorological And Climatic Disruption, Melanie Wetzel

Aviation / Aeronautics / Aerospace International Research Conference

Commercial and military flight operations are frequently imperiled or disrupted by meteorological conditions. Severe weather events and climate-related factors create aviation security impacts on airport siting and reliability, human safety, economic stability, military defense strategy, aircraft routing and computer systems vulnerability. Climate trends have been associated with increased frequency of storm surge incursions at coastal airports, intense snowfall accumulations, runway closures due to rainstorm runoff, extended periods of fog/stratus restrictions and severe-weather related risk from lightning, hail and icing. The economic and safety impacts of these events are being incorporated into long-term planning by the U.S. Department of Defense (DoD), …

Statistical Methods In Topological Data Analysis For Complex, High-Dimensional Data, Patrick S. Medina, R W. Doerge

Conference on Applied Statistics in Agriculture

The utilization of statistical methods an their applications within the new field of study known as Topological Data Analysis has has tremendous potential for broadening our exploration and understanding of complex, high-dimensional data spaces. This paper provides an introductory overview of the mathematical underpinnings of Topological Data Analysis, the workflow to convert samples of data to topological summary statistics, and some of the statistical methods developed for performing inference on these topological summary statistics. The intention of this non-technical overview is to motivate statisticians who are interested in learning more about the subject.

Best Linear Unbiased Prediction: An Illustration Based On, But Not Limited To, Shelf Life Estimation, Maryna Ptukhina, Walter Stroup

Conference on Applied Statistics in Agriculture

Shelf life estimation procedures, following ICH guidelines, use multiple batch regression with fixed batch effects. This guidance specifically mandates estimates based on at least 3 batches. Technically, the fixed-batch model limits inference to the batches actually observed, whereas ICH requires resulting estimates to apply to all future batches stored under similar conditions. This creates a conflict between the model used and the inference space the model is intended to address. Quinlan, et al. (2013) and Schwenke (2010) studied the small sample behavior of this procedure. Both studies revealed large sampling variation associated with the ICH procedure, producing a substantial proportion …

Shiga Toxin-Producing Escherichia Coli In Meat: A Preliminary Simulation Study On Detection Capabilities For Three Sampling Methods, Julie Couton, David Marx, John Luchaansky, Randall Phebus, Anna Porto-Fett, Nicholas Sevart, Manpreet Singh, Harshavardhan Thippareddi

Conference on Applied Statistics in Agriculture

Contamination by Shiga Toxin-producing Escherichia coli (STEC) is a continuing concern for meat production facility management throughout the United States. Several methods have been used to detect STEC during meat processing, however the excessive experimental cost of determining the optimal method is rarely feasible. The objective of this preliminary simulation study is to determine which sampling method (Cozzini core sampler, core drill shaving, and N-60 surface excision) will better detect STEC at varying levels of contamination present in the meat. 1000 simulated experiments were studied using a binary model for rare occurrences to find the optimal method. We found that …

Differential Methylation Methods In Multi-Context Organisms, Douglas Baumann, Yuqing Su, Iranga Mendis, Gayla R. Olbricht

Conference on Applied Statistics in Agriculture

DNA methylation is an epigenetic modification that has the ability to alter gene expression without any change in the DNA sequence. DNA methylation occurs when a methyl chemical group attaches to cytosine bases on the DNA sequence. In mammals, DNA methylation primarily occurs at CG sites, when a cytosine is followed by a guanine in the DNA sequence. In plants, DNA methylation can also occur in other cytosine sequences, such as when a cytosine is not followed directly by a guanine. Many of the statistical methods that have been developed to estimate methylation levels and test differential methylation in whole-genome …

On Fixed Effects Estimation In Spline-Based Semiparametric Regression For Spatial Data, Guilherme Ludwig, Jun Zhu, Chun-Shu Chen

Conference on Applied Statistics in Agriculture

Spline surfaces are often used to capture spatial variability sources in linear mixed-effects models, without imposing a parametric covariance structure on the random effects. However, including a spline component in a semiparametric model may change the estimated regression coefficients, a problem analogous to spatial confounding in spatially correlated random effects. Our research aims to investigate such effects in spline-based semiparametric regression for spatial data. We discuss estimators' behavior under the traditional spatial linear regression, how the estimates change in spatial confounding-like situations, and how selecting a proper tuning parameter for the spline can help reduce bias.

Small Sample Properties Of The Two Independent Sample Test For Means From Beta Distributions, Edward E. Gbur, Kevin Thompson

Conference on Applied Statistics in Agriculture

Researchers often collect proportion data that cannot be interpreted as arising from a set of Bernoulli trials. Analyses based on the beta distribution may be appropriate for such data. The SAS® GLIMMIX procedure provides a tool for these analyses using a likelihood based approach within the larger context of generalized linear mixed models (GLMM). The small sample behavior of likelihood based tests to compare the means from two independently sampled beta distributions were studied via simulation when the null hypothesis of equal means holds. Two simulation scenarios were defined by equal and unequal sample sizes and equal scale parameters. A …

Modeling The Occurrence Of Four Cereal Crop Aphid Species In Idaho, John W. Merickel, Bahman Shafii, Sanford D. Eigenbrode, Christopher J. Williams, William J. Price

Conference on Applied Statistics in Agriculture

Idaho is ranked 5^th in the United States in overall wheat production and makes over $500 million in profit annually from wheat. Many pests have detrimental effects on wheat; some of the most predominant ones are aphids. Four species of aphids having economic effects on wheat crops in Idaho are: Diuraphis noxia, Metopolophium dirhodum, Rhopalosiphum padi, Sitobion avenae. Predictive regression models could be useful for better understanding of the occurrence of these aphid species. Count data for the four species were collected over 17 years via suction traps at 12 locations in wheat fields throughout …
