Supplementing Cattle On Pasture: When, What And How Much?, Roy Burris Oct 2008

Supplementing Cattle On Pasture: When, What And How Much?, Roy Burris

Kentucky Grazing Conference

The biggest advantage of maintaining cattle in the southeast is our ability to grow forages. It is generally an economic advantage to make maximum use of our forage and then supplement only when needed to meet our production goals. Judicious use of extra nutrition to grazing cattle can allow us to meet an objective which was best stated by Hoveland in 1986:

“Our objective is to maintain pasture at the highest quality that the environment will allow and efficiently convert as much of the pasture as possible into saleable animal product.”

Practical Grazing Management And Feed Strategies To Alleviate Fescue Toxicosis, Glen Aiken Oct 2008

Practical Grazing Management And Feed Strategies To Alleviate Fescue Toxicosis, Glen Aiken

Kentucky Grazing Conference

Tall fescue grown in Kentucky is productive and persistent and that is why the state has 5 million acres of the stuff! Fescue has tolerances to drought, low fertility, and overgrazing that are attributed to a fungal endophyte which infects most tall fescue plants. Unfortunately, these advantages of tall fescue that livestock producers appreciate are offset by reduced calving percentages and calf weight gains caused by consumption of ergot alkaloids produced by the endophyte. Ergot alkaloids affect the physiology of cattle to cause elevation in body temperature, reduced sweating, retention of winter hair coats and uncontrollable growth of summer hair …


Herbicide Options For Pasture Weed Control, Jonathan D. Green Oct 2008

Herbicide Options For Pasture Weed Control, Jonathan D. Green

Kentucky Grazing Conference

Weeds have become more evident and problematic in grazed pastures as forage and livestock production systems have intensified. As animals consume the more desirable and palatable plant species in pastures, weedy plants become more abundant. In particular, animals tend to avoid grazing plants which contain thorns, prickly spines, or are unpalatable making some pastures less productive. In fact, many of the more problematic plants observed in Kentucky’s grazed pastures possess these characteristics including thistles, spiny amaranth (spiny pigweed), horsenettle, common cocklebur, tall ironweed, and buttercups.

Horse Pasture Monitoring Program: Results After Three Years, Tom Keene, S. Ray Smith

Kentucky Grazing Conference

Since 2001-2002 and the outbreak of Mare Reproductive Loss Syndrome (MLRS) the University of Kentucky has been developing stronger ties with the state’s equine industry. Approximately 30% of the foal crop was lost in the Central Bluegrass region during this period with a devastating impact on the industry. Traditionally, many Thoroughbred farms have functioned as independent entities, but MLRS helped them to realize that the University of Kentucky had tremendous amount of expertise that they could provide in the areas of animal health, forage management, and other areas. Initially, there were many theories as to the cause of MLRS with …


Forage Legumes Vs. Fertilizer Nitrogen, Garry D. Lacefield Oct 2008

Forage Legumes Vs. Fertilizer Nitrogen, Garry D. Lacefield

Kentucky Grazing Conference

A few weeks after I started to work as a Forage Extension Specialist at the University of Kentucky, I heard my mentor and forage idol, Mr. Warren Thompson, speak on forage legumes. Warren, along with Dr’s. Tim Taylor and W.C. Templeton had pioneered the “Pasture Renovation Program” in Kentucky. In addition, Mr. Ed Smith had joined the team and collectively they developed the “Power-til Pasture Renovator.” Warren began his presentation by talking about Kentucky Forages pointing out we were so fortunate to have a good grass base and the opportunity to grow lots of legumes. He also talked about all …


Growth Of Grasses And Legumes: Impact On Grazing, S. Ray Smith Oct 2008

Growth Of Grasses And Legumes: Impact On Grazing, S. Ray Smith

Kentucky Grazing Conference

The primary, cool season, perennial pasture grasses used in Kentucky are orchardgrass, bluegrass, and tall fescue. When not grazed or harvested, each of these passes through successive stages of growth in the spring: 1) leafy vegetative; 2) boot with seed heads enclosed in leaf sheath; 3) heading when the seed heads begin to show and, 4) bloom when pollination has occurred ( Figure 2). Since fiber and lignin contents increase steadily beyond the vegetative stage, while percent protein and digestibility decrease, a major goal in grazing management is to maintain these grasses in the leafy, vegetative stage at all times. …

Kamper Re-Visited Concert (Program), Klaus Kamper, Janet Bass Smith Oct 2008

Kamper Re-Visited Concert (Program), Klaus Kamper, Janet Bass Smith

Mammoth Cave Research Symposia

One hundred years ago, a young German engineer named Max Kämper, came as a visitor to Mammoth Cave. He became so enchanted with the cavern he obtained permission to map the vast system. For the next eight months Max, along with assistance from cave guide Ed Bishop, meticulously put together a highly detailed and accurate map revealing more of the cave than ever before. He probably never realized his work would be admired by generations to follow. Some admire its artistic expression of the cave. Others see beauty in its precision. Ultimately, it has become the iconic map for generations …


Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons Oct 2008

Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons

Mammoth Cave Research Symposia

Serving as guides and explorers at Mammoth Cave partially rescued four men from the obscurity of enslavement. Stephen Bishop, Materson Bransford, Nicholas Bransford and a young man named Alfred all had their very existence documented in the written journals and diaries of various nineteenth century Mammoth Cave visitors. They were physically described, their personalities contemplated, their intelligence gauged, their dialects imitated. At least one abolitionist characterized Stephen Bishop as a charismatic natural leader who could govern the citizenry of freed men in Liberia, should he choose to relocate there.


Max Kämper’S Introduction To The New World, Stanley D. Sides, M.D. Oct 2008

Max Kämper’S Introduction To The New World, Stanley D. Sides, M.D.

Mammoth Cave Research Symposia

Twenty-seven year old engineer Max Eduard Kämper arrived in America at 4:00 pm on May 16, 1907 and was greeted by a thunderstorm. His presumed goals were to study American manufacturing methods, learn English, and enrich himself musically. New York had so many German immigrants at the time that German was the second most common language spoken in the city. He stayed at the Belvedere House at the corner of 4th Avenue and 18th Street, and the next day visited acquaintances in Newark. He visited New York landmarks and May 20 visited the famed Hippodrome theater. He moved on May …


Searching For Max: The Engineer, The War And The World´S Longest Cave (Part 1), Bernd Kliebhan Oct 2008

Searching For Max: The Engineer, The War And The World´S Longest Cave (Part 1), Bernd Kliebhan

Mammoth Cave Research Symposia

In 1908 the German engineer Max Kämper mapped 35 miles of Mammoth Cave, KY. The “Kämper Map,” forgotten in the archives for half a century, is nowadays considered as a masterpiece of underground cartography. Little was known about Max Kämper despite several attempts of American speleo-historians. Most traces were wiped out in two world wars. Nevertheless the authors could find out details of the biography of Max Kämper in German archives. The text is based based upon the radio story “Suche nach Max,” broadcasted by Hessischer Rundfunk - hr1 December 26, 1999, audio download available on http://www.kliebhan.de/kaemper.htm

The Lamps That Lit Their Way, Rick Olson Oct 2008

The Lamps That Lit Their Way, Rick Olson

Mammoth Cave Research Symposia

The distinctive lanterns used at Mammoth Cave from the middle 1800s until 1938 appear to be a locally derived design. Early whale oil railroad lanterns share some characteristics of the Mammoth Cave lanterns, but L&N Railroad lanterns do not appear to have influenced the design. At this time, the design pathway appears to lead from simple open-flame tin candle lanterns to the same lantern with a petticoat lamp affixed in place of the candle, and then finally to the font or oil container being soldered onto the lamp base as one unit. This basic Mammoth Cave lantern varied somewhat over …

The Puzzling Mr. Janin And Mammoth Cave Management, 1900-1910, Katie Algeo Oct 2008

The Puzzling Mr. Janin And Mammoth Cave Management, 1900-1910, Katie Algeo

Mammoth Cave Research Symposia

Albert Covington Janin was the key architect of tourism development at Mammoth Cave for two decades at the start of the twentieth century, yet little has been written about his tenure. This paper explores his background and accomplishments for the period 1900 to 1910 as an initial attempt to understand his contributions to Mammoth Cave. Material about his activities in relation to Mammoth Cave is synthesized from primary sources in the archival collections of the Huntington Library (HL) of San Marino, California, and the Historical Society of Washington, DC (HSW).

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker Oct 2008

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker

Mammoth Cave Research Symposia

Maps came first at Mammoth Cave, Kentucky. Then came explorers who used the maps to make discoveries as they gained a more comprehensive understanding of the longest cave in the world. The saga of mapping at Mammoth Cave parallels the mapping of North America from the 1600s onward. The first map was an “Eye-Draught Map of Mammoth Cave”, penned from memory in 1811, not a survey, to acquaint merchants with the location of saltpeter dirt. In 1835 the managers of Mammoth Cave hired a surveyor, Edmond Lee, to survey and map and profile the main cave passages. Stephen Bishop, a …

Mammoth Cave Research Symposia

In this paper we present Max Kaemper’s unique selection of Place Names for his 1908 map of Mammoth Cave. He realized the importance of Place Names and they became a feature on his map. His sensitive selection of Place Names provides a greater cultural emphasis, when compared to the previous maps.


The Evolution Of Cave Mapping And Cartography, Pat Kambesis Oct 2008

The Evolution Of Cave Mapping And Cartography, Pat Kambesis

Mammoth Cave Research Symposia

“Does it go?” Is the initial question that has inspired many a cave explorer to push the extent of a cave system. But the answer only brings more questions…how far, how long, how deep does it go? During the exploration process, as a cave system reveals its complexity, the questions also change – what is the cave’s relationship to the surface, and to surrounding caves? What are the features and obstacles that the cave contains? Those involved in cave exploration know that the only way to answer these questions is with systematic documentation in the form of cave and surface …

Potential Antimicrobial Properties Of The Cyanobacterium Microcoleus Vaginatus In Relationship To The Moss Bryum Argenteum, Crystal Erickson, Lloyd Stark Aug 2008

Potential Antimicrobial Properties Of The Cyanobacterium Microcoleus Vaginatus In Relationship To The Moss Bryum Argenteum, Crystal Erickson, Lloyd Stark

Undergraduate Research Opportunities Program (UROP)

Biological soil crusts play important ecological roles in arid desert regions. These crusts cycle nutrients, prevent wind/water erosion, and form the basis of food chains and soil formation in desert communities. Primary components of these structures include two desert moss species Bryum argenteum and Syntrichia caninervis, and Microcoleus vaginatus, a cyanobacterium. Our Phase I experiment strongly suggests that in an environment of intense light, a condition of stress to Syntrichia caninervis, there is an increase in shoot regeneration when cyanobacteria are present compared to when they are absent. Microcoleus is a highly motile species and our lab observations of fewer …

Kentucky Alfalfa and Stored Forage Conference

Why Test Your Hay?

  • By knowing the percentages and protein levels you can increase/decrease the amount of supplements needed from your analysis report and will help the producer set feeding rations
  • If you do not know what you have in your forage you are over or under feeding your livestock – therefore affecting the health of your animal and your pocket book


Is There A Benefit To Alfalfa Balage?, Gary Bates Feb 2008

Is There A Benefit To Alfalfa Balage?, Gary Bates

Kentucky Alfalfa and Stored Forage Conference

Making hay in the mid-South has always been a difficult process. High humidity and rainfall often make drying a long, tedious, if not impossible proposition. Over the last few years there has been an increased interest in making round bale silage, or balage, from forage crops. Fermenting alfalfa for storage has several advantages and disadvantages over regular haymaking systems.

Kentucky Alfalfa and Stored Forage Conference

In 2007, U.S. farmers harvested 23.6 million acres of alfalfa. Alfalfa harvested as hay and haylage produced 82.8 million tons valued at approximately $9.4 billion, ranking behind only corn and soybeans. Alfalfa hay supports dairy, beef, sheep, and horse production in the U.S. as well as a growing export market.

National Hay Association President's Perspective: What A Year To Be President, Ron Tombaugh

Kentucky Alfalfa and Stored Forage Conference

Over the years, I have had the opportunity to attend the Kentucky Alfalfa Conference in Cave City. Usually it was combined with a trip to deliver hay into Kentucky to either a dairy, beef, or horse customer. This is an excellent event.

The following is my “acceptance” speech given in September 2007 in Columbus, Ohio, when I was installed as President of the National Hay Association.
