New Options For Extending Grazing, 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.

Dollars & Cents Of Intensive Grazing, Kenneth H. Burdine

Kentucky Grazing Conference

A rotational grazing system can generally be defined as the use of several pastures with one being grazed while the others are rested. On the contrary, conventional or continuous grazing systems allow livestock access to the entire pasture area and let them decide where, what, and how long to graze. In most cases, Kentucky pastures employing continuous grazing systems are too large for efficient management and forage utilization. In such instances, cattle overgraze more palatable forages and areas close to shade and water, while other sections of the pasture are underutilized. This leads to lower animal output per acre than …

Uk Horse Pasture Evaluation Program, Tom Keene, S. Ray Smith

Kentucky Grazing Conference

The University of Kentucky is developing stronger ties with the state’s horse industry in the areas of research, extension and teaching. Many horse farms in the bluegrass region are interested in UK’s assistance with pasture evaluation. During the fall of 2005 a team from the UK Forage Extension Program (Ray Smith, Tom Keene, Jesse Morrison, Gabriel Roberts) conducted a pilot project to evaluate horse pastures on 14 central KY farms. One of the focuses of the pilot was the evaluation of pastures for percent tall fescue and the potential of fescue stands to cause fescue toxicity in pregnant broodmares. We …

Managing Pasture Growth And Quality With Grazing, S. Ray Smith

Kentucky Grazing Conference

One of the keys to profitable livestock production is to minimize the costs of producing a marketable animal or animal product. Feed costs are commonly 70-80 percent of the cost of growing or maintaining an animal. Pastures provide feed at a cost of .01-.02 cents/lb of TDN while hay costs .04-.06 cents/lb TDN. Improved pasture management offers the single greatest opportunity to lower production costs, assuming that animal genetics, health, marketing procedures, and other areas of management have been addressed. A primary goal of livestock producers should be to utilize grazed forage for as many months of the year as …

Everyday Cattle Graze Is Money Saved, Garry D. Lacefield

Kentucky Grazing Conference

During one of my first visits to New Zealand over twenty years ago, I had the opportunity to visit many different dairy, beef, sheep and deer farms. While visiting a dairy farm, I remember the farmer telling me about his grazing program and their goal to “optimize grazing and minimize stored feed.” I remember him saying, “everyday grazed is money saved”. I admit, the reality of that statement didn’t truly sink in that day; but over the years, the truth of what he said has not only “sunk in” but has been reinforced by visits to other farms literally around …

Bermudagrass In Kentucky, David C. Ditsch

Kentucky Grazing Conference

Interest in bermudagrass [Cynodon dactylon (L.) Pers] is increasing in Kentucky as livestock producers continue their search for warm-season perennial forages capable of filling in the mid-summer growth slump we commonly experience with our traditional cool-season grasses. This is partially due to the recent availability of seeded bermudagrass varieties with improved winter hardiness thereby reducing establishment cost and increasing the odds of success.

Grazing Corn, Chad Lee

Kentucky Grazing Conference

Grazing is the cheapest form of feed for cattle. While perennial grasses and alfalfa are reliable components to a grazing system, another component could be corn.

Grazing corn is an option for a couple of situations: 1) as a bridge crop when pasture renovation is needed, and 2) as an insurance crop in an overall grazing system.

Why Dairy Farmers Need And Want High Quality Alfalfa Hay: Quality Of Hay = Performance And Profitability, Donna M. Amaral-Phillips

Kentucky Alfalfa and Stored Forage Conference

Why do dairy farmers want high quality forages, including alfalfa hay, to feed to their milking herds? Feeding high-quality forages results in greater feed intake and as a result, dairy cows produce more milk, and they often times can produce this milk more economically. With advancing stage of plant maturity, fiber digestibility and protein content of the alfalfa plant decreases while the amount of fiber increases. Consequently, less energy is available to the cow when it consumes more mature alfalfa. Energy is the nutrient that most often limits performance in dairy or beef cattle - not protein. The take home …

Alfalfa Hay For Horses, Robert Coleman

Kentucky Alfalfa and Stored Forage Conference

When horse owners consider hay for their animals 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 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 group of horse …

Interpreting Forage Quality Test Reports, Donna M. Amaral-Phillips

Kentucky Alfalfa and Stored Forage Conference

Forages are the foundation for building diets for beef and dairy cattle, horses, sheep and goats. The quality of these forages directly impacts forage intake, animal performance, and, ultimately, the profitability to their owners. As the quality of forages decline, consumption of that forage decreases and the amount of grain or byproducts which must be fed increases. The cost for a unit of performance increases and/or the animal can not perform (i.e. milk or gain) to the optimum level thus lowering profitability to the animal owner. These relationships are especially true with young and high performance ruminants, such as high …

Moisture Management In Hay Making And Storage, Tom Keene, Doug Overhults

Kentucky Alfalfa and Stored Forage Conference

Making hay in central Kentucky can be one of the most trying on farm endeavors a producer can undertake. Our plentiful moisture, rolling topography, and climate make Kentucky ideal for producing high quality forage for either grazing or hay making. However, that same moisture, either in the form of rain or high humidity, can sometimes make it devilishly hard to make hay here in Kentucky.

Storing Alfalfa As Round Bale Silage, David C. Ditsch

Kentucky Alfalfa and Stored Forage Conference

Hay is the most popular method for storing alfalfa because it stores well for long periods and is better suited to cash sale and transportation than silage. However, silage may be a suitable option when and/or where hay curing is difficult. Due to numerous improvements in baling and wrapping equipment, it is possible to make high quality round bale silage using long (unchopped) alfalfa crops.

Alfalfa As A Grazing Crop, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Over the past decade we have had several people address “Alfalfa as a Grazing Crop” including Warren Thompson, Jim Moutray, Gary Bates, Ken Johnson, Jason Sandefur, Byron Sleugh, and myself. Each has done an excellent job discussing the merits of this remarkable crop and the opportunities it offers for grazing. At the end of the Conference last year, I (as I always do) asked for your suggestions concerning topics for this years’ conference. As it has been for the past decade, “Grazing” was the most requested topic. In today’s presentation, let’s go back and revisit the question, “Is Grazing Alfalfa …

Fertilizing Alfalfa For Profit, 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. 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.

Principles And Practices Of Successful Alfalfa Establishment, Gary Bates

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the most widely known forage crop, due to its high quality and the versatility of use. There are few forages that are as widely distributed as alfalfa, and none that can produce the high yields and high quality. Even with all of the positives of alfalfa, growing this crop profitably is often difficult. An evaluation of alfalfa budgets shows that a key factor in the success with alfalfa is the stand life. Because of the establishment expense, an extra year or two of production can increase the lucrativeness of the stand. The start of having a long life …

Advances In Alfalfa Seed Coating, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

Seed coating for alfalfa has been available since the mid to late 70’s. Over the last 30 years, advances in the industry have made it the choice of many producers. The purpose of the coatings at that time was mainly to add weight to increase the ballistic properties and to be a carrier for the rhizobia. Through research and new technology, coatings have evolved and shown great agronomic benefits. Seed coating can provide an opportunity to supply effective quantities of needed materials to each seed, which can influence both the physical property, and the microenvironment of the seed. Coatings can …
