Why Dairy Farmers Need And Want High Quality Alfalfa Hay: Quality Of Hay = Performance And Profitability, Donna M. Amaral-Phillips
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
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
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
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
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
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
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
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
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 …
New Alfalfa Varieties, S. Ray Smith
New Alfalfa Varieties, S. Ray Smith
Kentucky Alfalfa and Stored Forage Conference
Commercial alfalfa breeding companies have continued to make great strides in the development of new varieties with unique traits. New traits include Roundup Ready®, potato leafhopper resistance, hybrids, lodging resistance, rapid regrowth, higher quality, resistance to new diseases, and more… I will address some of these new developments in the following pages. In addition, producers often ask the question: “Are improved varieties really worth the higher seed cost?” Dr. Jimmy Henning recently summarized 24 location years of Kentucky alfalfa yield data and found that the best 5 varieties in each test yielded 0.9 tons/A higher than the checks. Over a …

Perennial Warm Season Grasses In Grazing Programs, Mark Kennedy
Perennial Warm Season Grasses In Grazing Programs, Mark Kennedy
Kentucky Grazing Conference
Many warm season perennial grasses were once an important part of the plant community in much of the Midwest. Conversion to cropping systems, overgrazing, lack of regular fire and increased competition from cool-season grasses and legumes have caused many of these grasses to disappear from much of the region. However, warm season grasses can compliment cool-season pastures if managed properly. Midwest stockmen are rediscovering the usefulness of warm season grasses in their overall forage program. Adding these grasses to forage systems has resulted in increased gains and improved livestock performance during the summer months when cool-season grasses are at their …
Corn And Other Annuals, Jeff Mccutcheon
Corn And Other Annuals, Jeff Mccutcheon
Kentucky Grazing Conference
There are many factors to consider when planting alternative crops. One of the most important factors is deciding if you need additional forage. In our area the basis of any grazing system should be perennial cool-season grasses and legumes. Have you done all that you can to improve that forage production through managed grazing and fertility management? If you have, then you may be ready to consider annual forages in your grazing system.

Non-Traditional Forages For Grazing: Turnips And Other Brassicas, Dave Robison
Non-Traditional Forages For Grazing: Turnips And Other Brassicas, Dave Robison
Kentucky Grazing Conference
Over the past few years there have been a number of production livestock producers that have realized the benefits of grazing turnips and other brassicas. Turnips and other brassicas have traditionally been utilized for late season grazing to help extend the grazing season. But other ways are being found to utilize these highly productive, high quality forage crops. My purpose in this presentation is to introduce the different types of turnips and brassicas and explain how they can be utilized for various systems and different uses.

Developing Fencing For Grazing Systems, Ken Johnson
Kentucky Grazing Conference
Expectation is founded on faith, and in faith lays opportunities. I suppose as we look at most farming operations most changes occur from force not by choice. What I propose today and hope to convince most of you; is that here is an opportunity to make more profit, if you’re willing to change and have faith that it will work.
Developing Watering Systems For Efficient Grazing, Kevin Laurent
Developing Watering Systems For Efficient Grazing, Kevin Laurent
Kentucky Grazing Conference
Whether you call it rotational grazing, intensive grazing or management intensive grazing, the economic benefits of controlling how and where your cattle graze are well documented. Increased forage utilization, greater stocking rates, greater legume persistence, reduced hay feeding and more uniform nutrient recycling are just some of the many benefits producers can take advantage of when practicing some form of controlled grazing. However, one of the greatest challenges to implementing a controlled grazing system is the delivery of stock water to the grazing animal.
Mineral Supplements And Feed Additives--Can They Eliminate Fescue Toxicity?, John Thomas Johns
Mineral Supplements And Feed Additives--Can They Eliminate Fescue Toxicity?, John Thomas Johns
Kentucky Grazing Conference
Fescue is the predominate cool season grass in much of the United States due to its wide adaptation and hardiness. Many of these acres however, contain an endophytic fungus resulting in production of toxins with negative effects on grazing cattle. The two primary responses in beef cattle are an increase in core body temperature and a decrease in dry matter intake. As a result, decreases in reproductive rates, milk production, weaning weights and ADG are seen (Tables 1 and 2). Many approaches to pasture management have been advocated to overcome or minimize the problem such as incorporation of legumes, rotational …

Grazing Programs: Environmentally Friendly, Economically Sound And Agronomically Feasible, Sid Brantly
Kentucky Grazing Conference
The environmental soundness of our farms is the greatest, long term asset that farmers have. The topsoil, the trees, the cattle, the grass and crops on your farm are like unto a great financial account...and you are the banker. You make the decisions to: A) Use it all up now, B) Lock it away for someone in the future to make the decisions, or C) Utilize wisely in such a way that it is managed for financial success today, and still builds momentum for your future as well as your descendents.
Animal Behavior: Impacts On Grazing, Mark Kennedy
Animal Behavior: Impacts On Grazing, Mark Kennedy
Kentucky Grazing Conference
I am not an expert on this subject and give all credit for my limited understanding of this subject to Dr. Fred Provenza, Utah State University; Katy Voth, Livestock for Landscapes, LLC; Jim Gerrish and others. I have tried to put into practice, both personally and with other producers, many of these principles to aid in improved grazing management. This presentation will address only 2 aspects of animal behavior; 1) How animal behavior impacts grazing distribution and forage utilization over the landscape, and 2) How animal behavior affects diet selection.
Growing Forage Crops For Wildlife, Don Ball
Growing Forage Crops For Wildlife, Don Ball
Kentucky Grazing Conference
Numerous forage crops adapted in the Southeast offer benefits in production of various domestic animals including beef and dairy cattle, horses, and sheep (Ball, et al., 2002). Many of the same attributes these plants offer when grown in connection with livestock enterprises are also valuable in wildlife settings. Furthermore, the attitudes of many wildlife managers are changing, and their desire for knowledge of forage crops is on the rise. Consequently, forage crops are becoming more important and more greatly appreciated by wildlife enthusiasts within our region.
Maximizing Production Of Beef Cattle On Pastures, Justin Sexten
Maximizing Production Of Beef Cattle On Pastures, Justin Sexten
Kentucky Grazing Conference
Standardized performance analysis (SPA) of beef cattle operations continues to demonstrate the importance of reducing feed related costs. As producers look for alternative methods to reduce feed costs the benefits of improved forage management become increasingly important due to the opportunity to reduce feed costs while improving animal performance. One note of caution related to maximizing beef production from pasture, maximizing anything must be done carefully, the difference between maximum success and a total disaster is a fine line.
