What's New In Forage Equipment?, Dan Undersander

Kentucky Alfalfa and Stored Forage Conference

The forage equipment industry is changing in response to farmers’ needs. These changes consist of innovations to increase capacity, to improve the usability of the machine, and to improve the quality of the product. Most changes are occurring with existing equipment, but some totally new product innovations are occurring.

Dollars & Cents Of Alfalfa Production, Kenneth H. Burdine

Kentucky Alfalfa and Stored Forage Conference

The last several years have been incredibly challenging for all of Kentucky agriculture and hay producers have been no exception to the rule. Statewide, alfalfa yields have been below average in 3 of the last 4 years due to challenging weather in 2007, 2008, and again in 2010. In addition to the weather challenges, producers are also dealing with higher costs of fuel, fertilizer, and machinery. These challenges make budgeting especially important looking ahead to the 2011 growing season.

Alfalfa Hay For Horses: Myths Vs. Reality, Laurie Lawrence

Kentucky Alfalfa and Stored Forage Conference

Does it really matter if hay has some mold in it?

Hay that is high in dust or mold can irritate the horse’s respiratory tract. Optimum athletic performance depends on a healthy respiratory tract, therefore dusty/moldy hay should never be fed to horses used (or intended for) athletic events. A chronic respiratory disease commonly called “heaves” can be aggravated by moldy and dusty hay. Horses with heaves can have so much difficulty breathing that even mild exercise is impossible. In addition, moldy hay may contain toxins that could affect the horse if they are ingested.

Horse owners should not rely …

Hay Drying, Preservatives, Conditioning, Ash Content, Dan Undersander

Kentucky Alfalfa and Stored Forage Conference

Drying forage for hay has always been a challenge. While we cannot control the weather we can manage cut forage to maximize drying. The purpose of this paper is to give a few principles of hay and silage making and discuss machinery available relative to these principles. Then we will also talk about minimizing ash in hay to optimize the total digestible nutrients of the forage.

Making Your Fertilizer Dollar Go Further, Greg Schwab

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is a high quality, valuable forage crop that can be successfully produced on most well drained soils in Kentucky, for hay and silage, and for grazing. Fertilizing alfalfa can be uniquely challenging because it is a perennial crop. In addition, high-yielding alfalfa removes a tremendous amount of soil nutrients when compared to other crops grown in Kentucky. A thorough understanding of alfalfa’s growth habits, nutrient requirements, and the soil nutrient supply mechanisms for alfalfa is necessary to effectively manage fertilizer inputs and maximize profitability while minimizing the environmental impact.

Keys To Getting A Good Stand Of Alfalfa, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Profitable alfalfa production requires high yields of high quality forage, a long stand life and skillful marketing of the end product. This requires attention to details, timely action and advanced planning. There are four basic prerequisites for a successful alfalfa program: establishment, production, harvesting and marketing with a very specific goal within each component.

Alfalfa Varieties For Today And Tomorrow, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

There are a number of new alfalfa varieties that have come on the market in the last few years. In fact, it can be hard keeping up with all the developments. In the following pages I will overview most of the important traits that can be found in new varieties. These include Roundup Ready®, potato leafhopper resistance, hybrids, lodging resistance, rapid regrowth, higher quality, resistance to new diseases, and more… Many times I am asked “Are new varieties really worth the cost?” The best way to answer that question is to consider work by Dr. Jimmy Henning where he summarized …

Dusty Tori Of Luminous Type 1 Quasars At Z ~ 2, Rajesh P. Deo, Gordon T. Richards, Robert Nikutta, Moshe Elitzur, Sarah C. Gallagher, Željko Ivezić, Dean Hines

Physics and Astronomy Faculty Publications

We present Spitzer infrared (IR) spectra and ultraviolet (UV) to mid-IR spectral energy distributions (SEDs) of 25 luminous type 1 quasars at z ~ 2. In general, the spectra show a bump peaking around 3 μm and the 10 μm silicate emission feature. The 3 μm emission is identified with hot dust emission at its sublimation temperature. We explore two approaches to modeling the SED: (1) using the CLUMPY model SED from Nenkova et al. and (2) the CLUMPY model SED and an additional blackbody component to represent the 3 μm emission. In the first case, …

Differential Gene Expression In Liver And Small Intestine From Lactating Rats Compared To Age-Matched Virgin Controls Detects Increased Mrna Of Cholesterol Biosynthetic Genes, Antony Athippozhy, Liping Huang, Clavia Ruth Wooton-Kee, Tianyong Zhao, Paiboon Jungsuwadee, Arnold J. Stromberg, Mary Vore

Statistics Faculty Publications

BACKGROUND: Lactation increases energy demands four- to five-fold, leading to a two- to three-fold increase in food consumption, requiring a proportional adjustment in the ability of the lactating dam to absorb nutrients and to synthesize critical biomolecules, such as cholesterol, to meet the dietary needs of both the offspring and the dam. The size and hydrophobicity of the bile acid pool increases during lactation, implying an increased absorption and disposition of lipids, sterols, nutrients, and xenobiotics. In order to investigate changes at the transcriptomics level, we utilized an exon array and calculated expression levels to investigate changes in gene expression …

Extended Grazing And Reduced Stored Feed, Edward N. Ballard

Kentucky Grazing Conference

Feed costs represent the major cost in most livestock production systems. A recently completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation. Typically the cost of supplying nutrients to ruminant livestock is much greater using harvested feedstuffs as opposed to grazing pastures or crop residues. The primary function of a grassland farm is to convert solar energy to marketable livestock products in the most efficient manner. The fewer steps between the animal product and …

Grazing Non-Traditional Forages, Jeff Mccutcheon

Kentucky Grazing Conference

In the Heart of America region we are blessed with perennial cool-season grasses and legumes as the bulk of our forage production. Efficiently taking advantage of that perennial production is the focus of most grazing operations. Occasionally there are times when the production from our cool- season grass and legume pasture is not sufficient. In Ohio, that is late summer and late fall through winter till early spring. Nontraditional forages could be used when cool season forages are not producing. Non-traditional forages can provide a large volume, of high-quality feed during specific times of the year.

Grazing Goats And Cattle And Other Co-Species Grazing, Jason Tower

Kentucky Grazing Conference

Multispecies, co-species, mixed species grazing, it does not really matter what it is called they all revolve around the same premise; grazing more than one species of livestock on a given land area to improve resource use efficiencies.

Integrating Weed Management Practices To Enhance Productivity Of Grazed Pastures, Jonathan D. Green, Joshua Allen Tolson

Kentucky Grazing Conference

As animal grazing has intensified within Kentucky and the surrounding region problematic weeds such as tall ironweed, spiny amaranth, horsenettle, buttercup, common cocklebur, and thistles have been increasing. These weeds become prominent in pastures because they have spines, thorns, or are unpalatable to animals. Animals selectively graze and avoid these weedy plants and with intensive grazing practices their populations are allowed to increase. Livestock producers are seeking ways to increase pasture productivity by minimizing the impact of these and other weeds on grazed lands.

Mob Grazing, High Density Grazing, Management-Intensive Grazing: What's The Difference?, Mark Kennedy

Kentucky Grazing Conference

Before we can answer that question we need to review some basic fundamentals of successful grazing management. Four goals of any sustainable grazing management strategy should be: 1) Meet the nutritional needs of livestock from standing pasture as many days as possible; 2) Optimize pasture yield, quality and persistence; 3) Maintain or enhance the natural resource base; 4) Integrate the appropriate technology and knowledge into a practical and profitable system that fits your available resources and meets your objectives. We will use these goals to compare and contrast these 2 grazing management techniques. Both techniques should be considered tools in …

Organic Dairying: Role Of Grazing, Jake Schmitz

Kentucky Grazing Conference

Certified organic and many conventional dairy farmers are using grazing techniques for a number of reasons, including building better soil, reducing feed costs, improving milk quality, and enhancing herd health. Additionally, certified organic farmers must utilize their pastures because the United States Department of Agriculture’s (USDA) organic rule requires organic cows to graze. Both the farmer and the USDA are working hard to ensure that “organic dairy” is synonymous with “grazing cows,” because the organic consumer vehemently demands dairy products from pasture-grazed livestock.

Impact Of The Endophyte On Animal Production, Glen Aiken

Kentucky Grazing Conference

Tall fescue is productive and well adapted to the soils and climate in a region commonly referred to as the “fescue belt”, which overlays the transition zone between the temperate northeast and subtropical southeast. Persistence of the grass under low input management is attributed to a fungal endophyte that infects most fescue plants and produces alkaloids that impart tolerance to heat, drought, and grazing stresses. Unfortunately, the endophyte also produces ergot alkaloids that can induce toxicosis. Signs of “fescue toxicosis” are elevated body temperature and respiration rate, retention of winter hair coats through the summer months, hormonal imbalances, and reduction …

How Much Pasture Do I Have And How Long Will It Feed My Cows?, S. Ray Smith

Kentucky Grazing Conference

A very common question asked by cattlemen is, “How much pasture do I have and how long will it feed my cows.” The purpose of this paper is to provide some guidelines and tools for answering this question. In pasture systems, determining the amount of pasture is much harder than in grain-based feeding systems because feed may be allocated for more than one day and feed quantity and quality is influenced by weather, fertility, stand density, and season. In addition, not all the available forage is consumed and the plants continue to grow after they are grazed. Variation in quality …

From Confinement To Grazing, Bill Payne

Kentucky Grazing Conference

A Tale of Two Businesses:

I would like share an account of a transition from a conventional dairy operation to our current Management Intensive Grazing (MIG) enterprise. In 1974, I joined my father who had been dairying on a 265 acre farm in Lincoln County, Kentucky for twenty five years. We fed our registered Holsteins corn silage and alfalfa haylage and purchased a manufactured feed. Our herd of 70 Holsteins spent most of their time on concrete. We did make an effort to allow access to an exercise lot when weather permitted. However, during most of the 1990’s we spent …

Modeling, Analysis, And Simulation Of Discrete-Continuum Models Of Step-Flow Epitaxy: Bunching Instabilities And Continuum Limits, Nicholas O. Kirby

University of Kentucky Doctoral Dissertations

Vicinal surfaces consist of terraces separated by atomic steps. In the step-flow regime, deposited atoms (adatoms) diffuse on terraces, eventually reaching steps where they attach to the crystal, thereby causing the steps to move. There are two main objectives of this work. First, we analyze rigorously the differences in qualitative behavior between vicinal surfaces consisting of infinitely many steps and nanowires whose top surface consists of a small number of steps bounded by a reflecting wall. Second, we derive the continuum model that describes the macroscopic behavior of vicinal surfaces from detailed microscopic models of step dynamics.

We use the …
