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

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
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
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. …

Stereospecificity In Glucose Consumption: A New Approach To Martian Life Detection, Vienna R. Saccomanno, Henry J. Sun
Stereospecificity In Glucose Consumption: A New Approach To Martian Life Detection, Vienna R. Saccomanno, Henry J. Sun
Undergraduate Research Opportunities Program (UROP)
In 1976, the Viking mission made a remarkable discovery: Martian soil was capable of decomposing an organic nutrient broth to carbon dioxide as if it contained live microorganisms. However, a biological interpretation of this finding is in apparent contradiction with the gas chromatograph-mass spectrometer aboard the Viking landers, which showed Martian soil to be devoid of indigenous organics. To reconcile these findings, it has been hypothesized that unknown abiotic oxidants, such as peroxide and superoxide, are present on Mars and that they were responsible for its soil reactivity. The objective of this research is to develop a life detection method …

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 …

As we prepare for the 2008 hay crop, it’s probably a good time to look back and see what the ’07 crop brought to us and wonder if it will have any bearing on the upcoming 2008 crop.

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
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.

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.

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.

Kentucky Alfalfa and Stored Forage Conference
There is a growing demand in North America for the use of certified weed free hay and straw as a preventative program to limit the spread of noxious weeds. This voluntary certification program is designed to assure that hay and straw sold with proper certification identification meets minimum standards designed to limit the spread of noxious and undesirable weeds. Buyers are provided assurance that hay and straw certified through this program meets these minimum standards.

In the past, many university research trials and on-farm demonstrations have determined a range of cutting intervals for alfalfa. Most researchers have agreed that the optimum harvest frequency is about every 35 days to ensure top yields, without sacrificing too much in the way of forage quality and stand persistence. Others use a strategy of harvesting at 10% bloom.

Kentucky Alfalfa and Stored Forage Conference
On a hot day in August, I climbed into the dust-free air-conditioned cab of a new tractor to assist in a hay baling demonstration during a field day. Hay yield was low as a result of the drought, so it was important that I get everything from the small windrow. I adjusted the volume on the surround sound stereo where I had just inserted a CD of the Eagles Greatest Hits. Now we’re ready to bale – first let me check the GPS and get a check on the moisture of the hay coming into the bale chamber – moisture …
