How Good Is Our Kentucky Haylage? A Summary Of 2017-18 Farm Results, Jimmy C. Henning, Jeff Lehmkuhler, Levi Berg, April Wilhoit, Corinne Belton, Tommy R. Yankey

Kentucky Alfalfa and Stored Forage Conference

The ability to harvest moist forage as hay gives Kentucky producers many advantages, including timely harvest, higher forage quality, and less weathering loss over hay systems. The baleage system allows producers to utilize commonly available forage equipment (mowers, rakes, balers) rather than requiring choppers and silo structures or bags. Making high quality baleage requires timely access to bale wrappers.

Emerging Export Markets For High Quality Alfalfa Hay, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

The exporting of hay from country to country has been evolving for many years. When we look at today’s exports of American hay, we see that the majority of it takes place off the west coast.

Managing Frost Damaged Alfalfa Stands, Christopher D. Teutsch, Jimmy C. Henning, S. Ray Smith, Tom Keene, Matthew Dixon

Kentucky Alfalfa and Stored Forage Conference

Wide fluctuations in springtime temperature are common in Kentucky. Late freezing temperatures in the spring can cause damage to alfalfa depending on how far along it is in breaking dormancy. This publication provides information on the effect of low spring temperatures on both established and new alfalfa stands that have begun growth, as well as a method of predicting sensitivity to late frosts or freezes.

Harvesting Alfalfa For Quality, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be harvested for hay, baleage, silage, greenchop or grazing. Our goal is to produce, harvest and market high yielding-high quality forage. Profitable alfalfa programs consist of four basic phases and each phase have a specific goal.

Integrated Management Of Alfalfa Diseases, Kiersten A. Wise

Kentucky Alfalfa and Stored Forage Conference

Alfalfa diseases can reduce forage quality and the longevity of alfalfa stands. Integrated management of diseases can minimize disease impact and improve forage stand and quality. There are several important pathogens that cause disease on alfalfa, and the occurrence of these diseases, as well as the severity of damage, depend on several factors, including the type of pathogen, the environment, and the level of resistance of the host to a particular disease. In addition, disease presence and severity are also influenced by agronomic practices, particularly sowing dates, cutting dates and frequency, and fertility programs.

An Integrated Pest Management Ipm Approach In Alfalfa Production Systems, Lee H. Townsend

Kentucky Alfalfa and Stored Forage Conference

Alfalfa lends itself to an integrated pest management (IPM) approach for alfalfa weevils and potato leafhoppers, the two key insect pests of the crop. Both species live in most alfalfa fields every summer. However, alfalfa can tolerate low levels of their feeding without costly yield or quality loss.

An Integrated Approach To Weed Control In Alfalfa Production Systems, Jonathan D. Green

Kentucky Alfalfa and Stored Forage Conference

The importance of weed control in forage production should not be overlooked, especially when you consider the high investment associated with alfalfa and other legume forages. Weeds reduce forage yield by competing for water, sunlight, and nutrients. For example, yield obtained from the first cutting of alfalfa can be significantly reduced by a heavy infestation of common chickweed. In addition to yield losses, weeds can also lower forage quality, increase the incidence of disease and insect problems, cause premature stand loss, and create harvesting problems. Some weeds are unpalatable to livestock or, in some cases, may be poisonous.

Fertilizing High Producing Alfalfa Stands, Edwin L. Ritchey

Kentucky Alfalfa and Stored Forage Conference

There are no secrets for successfully producing a high quality alfalfa crop. Successful alfalfa production is a product of suitable site selection, proper fertility and pH management, good pest control, and favorable weather conditions throughout the season. This paper focuses on proper fertility and pH management practices.

Alfalfa Establishment: Getting Off To A Good Start!, Christopher D. Teutsch

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is a highly productive forage legume that is well adapted to transition zone states like Kentucky. It can be grazed, hayed, or ensiled. Once established and under good management, expected yields range from 5-7 tons per acre per year. High yields can only be obtained from a dense and vigorous alfalfa stand. The first step in obtaining such stands is establishment. The establishment phase of alfalfa production is critical since realization of returns from all other input costs is dependent upon having a good stand and it is expensive. It is important to remember that alfalfa establishment begins long …

Fine Tuning Varietal Selection For The Mid-South, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

There are many new alfalfa varieties that have come on the market each year. In fact, it can be hard keeping up with all the developments. In the following pages I will overview most of the important traits that can be found in new varieties. These include Low Lignin, Roundup Ready®, potato leafhopper resistance, higher quality, resistance to new diseases, and more… Many times I am asked “Are new varieties really worth the cost?” The best way to answer that question is to consider work by Dr. Jimmy Henning where he summarized 24 location years of Kentucky alfalfa yield data …

Selecting Summer Annual Varieties Using Yield And Digestibility, Christopher D. Teutsch

Kentucky Alfalfa and Stored Forage Conference

Although cool-season grasses can provide ample and high quality forage for grazing livestock in the spring and fall, forage growth during the summer months is often restricted by high temperatures (Figure 1). In contrast warm-season annual grasses are most productive during the summer months and do not reach peak growth until temperatures approach 90 degrees Fahrenheit. Summer annual grasses such as forage sorghum (Sorghum bicolor (L.) Moench), sudangrass (Sorghum bicolor (L.) Moench), sorghum-sudangrass hybrids, and pearl millet (Pennisetum americanum (L.) Leeke) can provide high quality summer grazing for ruminant livestock in many regions of the United States.

The Economics Of Hay Quality, Madeline L. Dant, Kenneth H. Burdine, Brandon Sears

Kentucky Alfalfa and Stored Forage Conference

Hay quality is often discussed when one considers the viability of cash hay operations. A great deal is known about how production impacts quality and how quality impacts animal performance. This knowledge certainly has economic implications, but the economics of hay quality has primarily been evaluated from the animal performance perspective. Analyzing the economics of hay quality from the cash hay producer’s prospective becomes more difficult due to data limitations.

There are approximately 2.5 million acres of hay produced in Kentucky annually. The vast majority of this hay is grass type hay that is produced and fed on beef cattle …

What Is New In Seed Coatings, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

Seed Coatings started many centuries ago when the Chinese wrapped their rice seed in a mud ball when planting their rice fields. The ball would keep the seed from floating to the top when they flooded their fields. Seed treatment of Alfalfa first began with preinoculation of the seed to make it more convenient to plant. The farmer did not have to go through the process of inoculating the seed himself, and this was a great improvement at the time. In 1975 Ramsey Seed in California acquired technology from a New Zealand company to begin coating seed with a buildup …

Western Hay Production Vs. Eastern Hay Production, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

Early in the history of mankind, man was nomadic and moved from location to location in order to gather and find sustenance for themselves as well as their livestock. At some point in time, man decided that rather than keep moving, they would establish a community in one location, usually near running water (or fresh water of some kind), and would begin to sustain themselves with production agricultural practices.

Planting and harvesting soon took the place of packing up and moving every time the current resources had been depleted. Each year a new crop would be planted; livestock also became …

Why Is Intake Reduced When Cattle Are Fed Tall Fescue?, James L. Klotz

Kentucky Alfalfa and Stored Forage Conference

A major problem for the cattle producer that utilizes tall fescue forage is the unrealized or reduced gains in body weight in growing animals. This result has been reproduced across numerous studies evaluating cattle performance on tall fescue (Hoveland et al., 1983; Boling, 1985; Schmidt et al., 1986; Goetsch et al., 1987). Cattle have gained from 30 to 100% less consuming toxic endophyte-infected tall fescue compared to consumption of an endophyte-free tall fescue (Paterson et al., 1995). This effect of reduced gain is a consequence of a fungal endophyte present within the grass that produces toxins called ergot alkaloids. Fungal …

Understanding And Improving Fermentation In Alfalfa And Grass Baleage, Dennis Hancock

Kentucky Alfalfa and Stored Forage Conference

The ancient Egyptian and Carthaginians are believed to be the first conserve forage by ensiling it in the absence of oxygen. Though the technique has been refined in the 3500 years since, the basic fermentation process has not changed. Populations of naturally-occurring bacteria on the plant surface can consume some of the readily available carbohydrates and produce organic acids. These organic acids lower the pH of the forage material and prevent fungal deterioration of the product. Fermentation has been used for millennia as a natural method for preserving food. Similar bacterial fermentation occurs when one makes yogurt, sour cream, or …

Hay Making Weather In Kentucky: How To Get Good Information, Matthew Dixon, Tom Priddy

Kentucky Alfalfa and Stored Forage Conference

The UK Agricultural Weather Center, housed within the Department of Biosystems and Agricultural Engineering, was developed in 1978. As part of the Cooperative Extension Service, the goal of the Ag Weather Center is to minimize weather and climate related surprise for Kentucky residents and their agricultural needs, ultimately for profitable and sustainable production. In doing so, numerous tools and models have been developed throughout the years to further help farmers and producers in management and production related decisions.

Hay Quality: What Is It?, Garry D. Lacefield, Don Ball

Kentucky Alfalfa and Stored Forage Conference

Profitable livestock production almost always requires a forage program that will supply large quantities of adequate quality, homegrown feed. A major percentage of the feed units for beef (83%) and dairy cattle (61%) come from forages. In addition, forages supply an estimated 91%, 72%, 15% and 99% of the nutrients consumed by sheep and goats, horses, swine, and wildlife, respectively.
