Strategies To Minimize The Effects Of Drought, Gary Bates Oct 2012

Strategies To Minimize The Effects Of Drought, Gary Bates

Kentucky Grazing Conference

As this summer has shown, forage production from cool-season pasture and hay fields across the state can be dramatically affected by drought. Pastures that consist of cool-season grasses like tall fescue and orchardgrass have been severely overgrazed, and many may have lost some significant stand. Even if you have reseeded these fields, the question is how to prevent having the same problem next year. One of the best practices is to develop a forage program that doesn’t rely on cool-season grasses for summer production, but selects forage species that are better able to produce during periods of limited rainfall and …


Grassfed Beef From A Global Perspective, Glen Aiken Oct 2012

Grassfed Beef From A Global Perspective, Glen Aiken

Kentucky Grazing Conference

Beef production and marketing has been shifting over the last few decades in response to unstable cattle markets, higher input costs, and a need to better meet market demands. Advancement of vertical integration of the production and marketing of beef calves through retained ownership from suckling calf to feedyard has certainly enhanced the genetics of the U.S. beef herd and improved the consistency of beef products. Another shift in production has been an increased number of grassfed cattle (grass finished) for marketing either organic or locally grown beef. These niche markets have developed primarily from concerns of urban consumers regarding …


The Cost Of Pasture Versus Hay, Kenneth H. Burdine Oct 2012

The Cost Of Pasture Versus Hay, Kenneth H. Burdine

Kentucky Grazing Conference

Whenever I discuss the economics of grazing, I like to start by thinking about hay production costs. Regardless of which species we are talking about, a livestock producer should know what his / her most expensive feeding days are. In most cases, these will be winter feeding days, and that will generally consist of feeding either purchased or home-grown hay. So, I encourage producers to start by getting a solid feel for what their daily winter feeding costs are. For the purposes of this article, I am going to present some specific estimates for winter feeding costs, and other items, …


Pastures For Horses, Robert Coleman Oct 2012

Pastures For Horses, Robert Coleman

Kentucky Grazing Conference

For horse owners, the use of pasture in the daily management of their horses provides both exercise for the horses, but also is a valuable source of nutrients. Horse feeding programs are based on forage and pasture is an excellent means to supply nutrients. To make effective use of the forage, horse owners need to manage both the horse and the grass.


Winter Annuals And Short Term Perennials For Grazing, S. Ray Smith Oct 2012

Winter Annuals And Short Term Perennials For Grazing, S. Ray Smith

Kentucky Grazing Conference

During the last 5 years there has been a renewed interest in winter annual and short term perennials for grazing and for stored feed. There are many sources of information on this subject. I especially encourage you to read the new publication written by Dr. Garry Lacefield and colleagues, “Extending Grazing and Reducing Stored Feed Needs”. 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. This website contains many use publications on the subject of winter annuals and variety trial information on annual ryegrass and …


Novel Endophyte Tall Fescue, Garry D. Lacefield Oct 2012

Novel Endophyte Tall Fescue, Garry D. Lacefield

Kentucky Grazing Conference

“Novel” endophyte is a term used to describe a “good” or “friendly” fungus (endophyte) in tall fescue as opposed to the endophyte that’s present if over eighty-five percent of the tall fescue in the Fescue Belt of the USA. This endophyte is costing beef producers an estimated $1 Billion dollars in losses from animal gains, reproduction and overall performance.

Chemistry Faculty Publications

The objective of this study was to determine the residual pro-or anti-oxidant effects in rat brain 30 days after systemic administration of a 5 nm citrate-stabilized ceria dispersion. A ∼4% aqueous ceria dispersion was iv-infused (0 or 85 mg/kg) into rats which were terminated 30 days later. Ceria concentration, localization, and chemical speciation in the brain was assessed by inductively coupled plasma mass spectrometry (ICP-MS), light and electron microscopy (EM), and electron energy loss spectroscopy (EELS), respectively. Pro- or anti-oxidant effects were evaluated by measuring levels of protein carbonyls (PC), 3-nitrotyrosine (3NT), and protein-bound-4-hydroxy-2-trans-nonenal (HNE) in the hippocampus, cortex, and …


Improving Woody Biomass Estimation Efficiency Using Double Sampling, David L. Parrott, John M. Lhotka, Songlin Fei, B. Scott Shouse May 2012

Improving Woody Biomass Estimation Efficiency Using Double Sampling, David L. Parrott, John M. Lhotka, Songlin Fei, B. Scott Shouse

Forestry and Natural Resources Faculty Publications

Although double sampling has been shown to be an effective method to estimate timber volume in forest inventories, only a limited body of research has tested the effectiveness of double sampling on forest biomass estimation. From forest biomass inventories collected over 9,683 ha using systematic point sampling, we examined how a double sampling scheme would have affected precision and efficiency in these biomass inventories. Our results indicated that double sample methods would have yielded biomass estimations with similar precision as systematic point sampling when the small sample was ≥ 20% of the large sample. When the small to large sample …

Farmer Panel--Getting More From Your Alfalfa, Charles Powell Feb 2012

Farmer Panel--Getting More From Your Alfalfa, Charles Powell

Kentucky Alfalfa and Stored Forage Conference

Powell Farms started in 1996 with 15 acres of Alfalfa hay intended for cow/calf feed. A neighbor and his friends bought every bale that year. Over the next 14 years the only alfalfa hay our cows got to eat was when a cutting got wet and was rolled. Production per acre was good, demand exceeded production and price per bale continued to rise. Roundup Ready came on the market and we were finally able to produce clean pure high quality alfalfa. All was going well for our alfalfa business. Then came the 2008 challenge with the economic down turn, drought …

Role And Importance Of Alfalfa In Beef Diets, Jeff Lehmkuhler Feb 2012

Role And Importance Of Alfalfa In Beef Diets, Jeff Lehmkuhler

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is often referred to as the “Queen” of forage. Is this because of its high fertility needs and more finicky soil fertility needs along with greater management for optimal growth and persistency? Or is it because of it being on top of nearly all other forages for yield and quality? Truth be told, it is likely a combination of all these factors. Alfalfa is a versatile forage as it can be harvested for hay or silage and also grazed with proper management. For these reasons, this forage can fit well in beef operations.


Alfalfa Hay For Horses, Robert Coleman Feb 2012

Alfalfa Hay For Horses, Robert Coleman

Kentucky Alfalfa and Stored Forage Conference

When horse owners consider hay for their horses, a number of criteria are generally considered. Of major importance is the hay must be free of mold and dust. It needs to contain nutrients needed by the horse and it must be palatable. If these criteria are met, the type of hay should not matter. However, that is not the case with many horse owners. When discussing the selection of hay, many owners first consider the type of hay. Can it be alfalfa or should it be a grass or how about a mix of grass and a legume. If a …

Status And New Developments In Seed Coatings, Bill Talley Feb 2012

Status And New Developments In Seed Coatings, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

The acceptance and use of coated alfalfa seed has become the standard of how alfalfa seed is being sold. Coated seed, refers to a buildup in coating material of 10-34%. Seventy percent of proprietary alfalfa seed is now buildup coated, and 80 % of that amount is a 34% coating. The remaining is a 10% buildup and is usually only used as a carrier for inoculation and fungicide. The higher buildup coatings are able to carry more active ingredients that also enhance the agronomic benefit to the young seedling. The benefits to the young seedling, from the components of the …

Marketing Quality Hay, Tom Keene Feb 2012

Marketing Quality Hay, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

When marketing quality alfalfa hay, you basically have two markets that you are going to try to target. First, you are going to be in the cash hay market, that’s where you will sell alfalfa hay to several different entities…..locally, statewide, nationally, or potentially internationally. Secondly, and more commonly, you will be marketing your hay to your own livestock enterprise on your farm. Several times every month, I have people call me and ask me what their hay is worth. I tell them very honestly I have no idea what their hay is worth; only by keeping track of their …
