The Great Debate of Annual vs. Perennial Forages

3/13/2024 (new)
Authors: Kenny Burdine, Kelly Mercier, Ray Smith

The organic dairy sector in Kentucky and Tennessee contributed $9.3 million in organic product sales in 2019 (USDA-NASS, 2020), with organic milk sales in Kentucky alone rising 61% from 2017 to 2019 (USDA, NASS, Kentucky Field Office, 2020). Organic dairies rely more heavily on pastures as a significant source of dry matter intake compared to most conventional dairies.

2023 Alfalfa Report

12/18/2023 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

Alfalfa (Medicago sativa) has historically been the highest-yielding, highest-quality forage legume grown in Kentucky. It is an important part of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Choosing a good variety is a key step in establishing a stand of alfalfa. The choice of variety can impact yield, thickness of stand, and persistence.

2023 Orchardgrass Report

12/18/2023 (new)
Authors: Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is well-adapted to Kentucky conditions. This grass is used for pasture, hay, green chop, and silage, but it requires better management than tall fescue for greater yields, higher quality, and longer stand life. It produces an open, bunch-type sod, making it compatible with alfalfa or red clover as a pasture and hay crop or as habitat for wildlife.

2023 Alfalfa, Red Clover, and White Clover Grazing Tolerance Report

12/18/2023 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

Alfalfa (Medicago sativa) is the highest-yielding, highest-quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Recent emphasis on its use as a grazing crop and the release of grazing-tolerant varieties have raised the following question: Do varieties differ in tolerance to grazing? To answer this question, we have chosen to use the standard tolerance test recommended by the North American Alfalfa Improvement Conference. This test uses continuous heavy grazing to sort out differences in grazing tolerance in a relatively short period of time.

2023 Red and White Clover and Annual Lespedeza Report

12/12/2023 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

Red clover (Trifolium pratense L.) is a high-quality, short-lived, perennial legume used in mixed or pure stands for pasture, hay, silage, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. Stands of improved varieties generally are productive for 2.5 to 3 years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures and hay fields. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, yield, and animal acceptance.

Tall Fescue Novel Endophyte Varieties and Establishment for Livestock and Horse Farms

11/2/2023 (new)
Authors: Krista Lea, Stephanie Smith, Ray Smith

"Endophyte" refers to a fungus that lives within the fescue plant, meaning it cannot be seen with the naked eye. The endophyte found in tall fescue is beneficial to the plant: It gives tall fescue insect resistance, enhanced grazing tolerance, and greater persistence in stressful environments. The major disadvantage of some of the endophytes of tall fescue is that they produce toxic alkaloids that have detrimental effects on many types of livestock.

Frost Seeding Clover: A Recipe for Success

3/2/2023 (new)
Authors: Jimmy Henning, Ray Smith, Chris Teutsch

Legumes are an essential part of a strong and healthy grassland ecosystems. They form a symbiotic relationship with Rhizobium bacteria in which the bacteria fix nitrogen from the air into a plant-available form and share it with the legume. Clover also increases forage quality and quantity and helps to manage tall fescue toxicosis. In the past, the positive impact of clover on tall fescue toxicosis has always been thought to simply be a dilution effect, but new research from the USDA's Forage Animal Production Unit in Lexington shows that compounds found in red clover can reverse vasoconstriction that is caused by the ergot alkaloids in toxic tall fescue. The primary compound found in red clover is a vasodilator called "Biochanin A."

Forage-Related Disorders in Cattle: Nitrate Poisoning

10/24/2022 (minor revision)
Authors: Michelle Arnold, Jeff Lehmkuhler, Megan Romano, Ray Smith

Nitrates are natural constituents of all plants. Under normal conditions, plants take up nitrate through their roots and transport it to the leaves for use in photosynthesis. However, photosynthesis decreases under adverse environmental conditions (e.g., drought; leaf damage due to disease, hail, frost, insects, or herbicides; cool and cloudy weather; and other plant stressors). When photosynthesis is reduced, nitrate transportation to the leaves slows also. Potentially toxic nitrate concentrations can remain in the lower stalks and stems.

Growing Wheat for Forage

4/14/2021 (new)
Authors: Jimmy Henning, Tim Phillips, Ray Smith, Chris Teutsch

Wheat is a multipurpose crop that can be used for cover crops, stored forage or grazing. As much as 25% of Kentucky's wheat acreage is not harvested as grain but used for cover crop or forage production. Wheat has excellent winter hardiness and can be sown later in the fall than barley. Wheat is a good choice for planting following corn or soybean harvest to capture residual nitrogen, build soil organic matter and prevent erosion. Wheat provides high quality, early spring growth, but has limited fall growth compared to grazing types of cereal rye.

Crabgrass

4/6/2021 (minor revision)
Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Crabgrass possesses significant potential for supplying high quality summer forage although it is considered a weed by many. A primary advantage of crabgrass is that it is well adapted to Kentucky and occurs naturally in most summer pastures, especially those that have been overgrazed. It is also highly palatable and a prolific re-seeder. Planting an improved variety of crabgrass is recommended because the production of naturally-occurring ecotypes varies greatly. Crabgrass is best utilized by grazing.

Kentucky is ideally suited for cattle production. The main feed for cattle is a renewable resource Kentucky has in abundance--forages. The majority of the state's terrain favors cattle production over row crops. Kentucky farms cover 14 million acres, with approximately half of that occupied by forage grasses and legumes. Our natural resources and climate permit the growth of most cool-season and warm-season species. Water is readily available in all areas of the state, and we have a relatively long growing season.

Blackpatch of Forage Legumes: Cause of Slaframine Toxicosis or "Slobbers" in Animals

3/5/2021 (major revision)
Authors: Michelle Arnold, Shane Bogle, Bob Coleman, Ray Smith, Kiersten Wise

Blackpatch is an important fungal disease of forage legumes in Kentucky. A metabolite produced by the fungus can result in slaframine toxicosis or "slobbers" in many animals. The fungal disease was first reported in Kentucky in 1933 on red clover. Most Extension literature associates blackpatch and slaframine with red clover, which is very susceptible to the disease. However, many forage legumes including alfalfa can be infected by the causal fungus.

Utilizing Drought Stressed Soybeans for Forage

2/10/2021 (new)
Authors: Jimmy Henning, Ray Smith, Chris Teutsch, Katherine VanValin

Although soybeans are commonly grown as a grain crop, they can be grazed or harvested as either a hay or silage crop. This most commonly occurs when the grain potential of the soybean crop has been reduced by drought, hail damage, or early frost. A realistic forage yield expectation for drought stressed soybeans would be 1.5 to 2.0 tons of dry matter per acre. The objective of this article is to provide practical tips for successfully, grazing, conserving and feeding drought stressed soybeans.

Baling Forage Crops for Silage

1/11/2021 (major revision)
Authors: Jimmy Henning, Ray Smith, Chris Teutsch

Forage may be stored for winter feeding when pasture production is limited, for use in confinement feeding systems, or for cash hay. Dry hay is the most popular storage method since it stores well for long periods and is better suited to cash sale and shipping than high moisture forages. However, silage may be more suitable in situations where hay curing is difficult. It is possible to make high quality silage or haylage using long (unchopped) forage crops baled with large round balers, although balers may need modification to handle wet material.

Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past twenty years.

2020 Tall Fescue and Bromegrass Report

Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

Tall fescue (Festuca arundinacea) is a productive, well-adapted, persistent, soil-conserving, cool-season grass grown on approximately 5.5 million acres in Kentucky. This grass, used for both hay and pasture, is the forage base of most of Kentucky's livestock enterprises, particularly beef cattle. Much of the tall fescue in Kentuckys infected with an internal fungus (endophyte) that produces ergot alkaloids and results in decreased weight gains in growing ruminants and lower pregnancy rates in breeding stock, especially in hot weather. Varieties are now available that are free of this fungal endophyte or infected with a nontoxic endophyte. Varieties in the latter group are also referred to as "novel" or "friendly" endophyte varieties, because their endophyte improves stand survival without creating animal production problems.

Alfalfa (Medicago sativa) is the highest-yielding, highest-quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Recent emphasis on its use as a grazing crop and the release of grazing-tolerant varieties have raised the following question: Do varieties differ in tolerance to grazing? We have chosen to use the standard tolerance test recommended by the North American Alfalfa Improvement Conference. This test uses continuous heavy grazing to sort out differences in grazing tolerance in a relatively short period of time. This report summarizes research on the grazing tolerance of alfalfa varieties when subjected to continuous heavy grazing pressure during the grazing season.

Forage Sorghum

2/19/2018 (new)
Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Forage sorghum is the tallest of the summer annuals, reaching 6 to 15 feet in height and is best harvested as silage. Taller varieties produce high forage yield but can lodge, making them difficult to harvest mechanically. Some varieties have been developed that are shorter with increased resistance to lodging. Forage sorghums, like corn, are harvested once per season by direct chopping. While forage sorghum yields are similar to corn, they are lower in energy. The primary advantage of utilizing sorghum for silage production is its greater drought tolerance.

Authors: Jimmy Henning, Tom Keene, Ray Smith, Chris Teutsch

Sorghum-sudangrass hybrids are developed by crossing sorghum with true sudangrass. The result is an annual grass that resembles sudangrass, but has coarser stems, taller growth habit, and higher yields. Like sudangrass, hybrids will regrow after grazing if growth is not limited by environmental factors. The coarse stems are difficult to cure as dry hay, therefore these grasses are best utilized for grazing, chopped silage and baleage.

Pastured Poultry

9/21/2017 (new)
Authors: Jacquie Jacob, Tony Pescatore, Ray Smith

There has been an increased interest in pasture-raising poultry for both meat and egg production in the last decade. Raising poultry on pasture was a common occurrence until the latter half of the 20th century. Fresh forage provided an important ration balancing factor during the years before poultry nutritionists fully understood the required essential vitamins and minerals for growth and optimum meat and egg production. With the development of balanced rations, poultry no longer require access to pasture and year-round production of meat and eggs is possible. However, there are still some benefits from the lush forage, invertebrates, and exercise that pasture provides. In addition, we continue to learn more and more about the positive influence that fresh grasses and legumes have on fatty acid profiles and general bird health. As a result, there is an increased interest in pasture-raised poultry for both meat and eggs.

Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands

4/10/2017 (minor revision)
Authors: Ray Smith, Tina Tillery, Paul Vincelli

Most of the tall fescue growing in Kentucky is colonized by the tall fescue endophyte, a fungus which causes disorders in livestock that feed on the infected grass. The animal disease syndrome is called fescue toxicosis, which some researchers estimate may cost Kentucky producers over $200 million yearly. This problem can be greatly reduced by identifying the infected fields and replacing them with endophyte-free or novel endophyte tall fescue varieties or by managing them in a way to minimize the impact of the endophyte on herd productivity. One of the simplest ways to reduce toxicity symptoms in cattle is add red and white clover to existing tall fescue stands.

Authors: Gene Olson, Tim Phillips, Ray Smith

Timothy (Phleum pratense) is the fourth most widely sown cool-season perennial grass used in Kentucky for forage--after tall fescue, orchardgrass, and Kentucky bluegrass. It is a late-maturing bunchgrass that is primarily harvested as hay, particularly for horses. It also can be used for grazing or wildlife habitat. Management is similar to that for other cool-season grasses. Kentucky bluegrass (Poa pratensis) is a high-quality, highly palatable, long-lived pasture plant with limited use for hay. It tolerates close, frequent grazing better than most grasses. It has low yields and low summer production and becomes dormant and brown during hot, dry summers. Kentucky bluegrass is slow to establish. This report provides maturity and yield data on timothy and Kentucky bluegrass varieties included in yield trials in Kentucky.

Annual ryegrass (Lolium multiflorum) and perennial ryegrass (Lolium perenne) are high-quality, productive, cool-season grasses used in Kentucky. Both have exceptionally high seedling vigor and are highly palatable to livestock. In Kentucky, winter survival can be an issue for many annual ryegrass varieties, so before planting, review winter survival results in this publication. The severe winter of 2013-2014 showed those varieties that are not adapted to Kentucky. Festuloliums are hybrids between various fescues and ryegrasses with higher quality than tall fescue and improved stand survival over perennial ryegrass. Their use in Kentucky is still limited since they do not survive as long as tall fescue but some of the newer varieties are more adapted to Kentucky environmental conditions. This report provides current yield data on annual and perennial ryegrass varieties in trials in Kentucky as well as guidelines for selecting varieties, as well as summaries of all annual and perennial ryegrass and festulolium varieties tested in Kentucky for the last 15 years.

2016 Red and White Clover Grazing Tolerance Report

11/17/2016 (new)
Authors: Joey Clark, Gene Olson, Ray Smith

Red clover (Trifolium pratense L.) is a high-quality, short-lived perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, soil improvement, and wildlife habitat. White clover (Trifolium repens L.) is a low-growing, perennial pasture legume with white flowers. It differs from red clover in that the stems (stolons) grow along the surface of the soil and can form adventitious roots that may lead to the development of new plants. This report summarizes research on the grazing tolerance of clover varieties when subjected to continuous grazing pressure.

2015 Long-Term Summary of Kentucky Forage Variety Trials

12/15/2015 (new)
Authors: Gene Olson, Ray Smith

Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past 12 to 15 years.

2015 Alfalfa Grazing Tolerance Report

12/14/2015 (new)
Authors: Joey Clark, Gene Olson, Ray Smith

Alfalfa (Medicago sativa) is the highest-yielding, highest-quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Recent emphasis on its use as a grazing crop and the release of grazing-tolerant varieties have raised the following question: Do varieties differ in tolerance to grazing? We have chosen to use the standard tolerance test recommended by the North American Alfalfa Improvement Conference. This test uses continuous heavy grazing to sort out differences in grazing tolerance in a relatively short period of time. This report summarizes research on the grazing tolerance of alfalfa varieties when subjected to continuous heavy grazing pressure during the grazing season.

Cool-season grasses such as tall fescue, orchardgrass, and Kentucky bluegrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and the brome grasses can be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, perennial ryegrass, and other species when they are subjected to continuous, heavy grazing pressure by cattle within the grazing season.

Authors: Gene Olson, Tim Phillips, Ray Smith

Timothy (Phleum pratense) is the fourth most widely sown cool-season perennial grass used in Kentucky for forage--after tall fescue, orchardgrass, and Kentucky bluegrass. It is a late-maturing bunchgrass that is primarily harvested as hay, particularly for horses. It also can be used for grazing or wildlife habitat. Management is similar to that for other cool-season grasses. Kentucky bluegrass (Poa pratensis) is a high-quality, highly palatable, long-lived pasture plant with limited use for hay. It tolerates close, frequent grazing better than most grasses. It has low yields and low summer production and becomes dormant and brown during hot, dry summers. Kentucky bluegrass is slow to establish. This report provides maturity and yield data on timothy and Kentucky bluegrass varieties included in yield trials in Kentucky.

Authors: David Ditsch, Gene Olson, Tim Phillips, Ray Smith

Tall fescue is a productive, well-adapted, persistent, soil-conserving, cool-season grass grown on approximately 5.5 million acres in Kentucky. This grass, used for both hay and pasture, is the forage base of most of Kentucky's livestock enterprises, particularly beef cattle. All bromegrasses have several advantages over tall fescue, including retaining quality as they mature and better growth during dry weather, but they are generally less well adapted in Kentucky. This report provides current yield data on tall fescue varieties and similar grass species in trials in Kentucky as well as guidelines for selecting tall fescue varieties, including summaries of all tall fescue and bromegrass varieties tested in Kentucky for the past 15 years.

2015 Annual and Perennial Ryegrass and Festulolium Report

12/8/2015 (new)
Authors: Gene Olson, Tim Phillips, Ray Smith

Annual ryegrass (Lolium multiflorum) and perennial ryegrass (Lolium perenne) are high-quality, productive, cool-season grasses used in Kentucky. Both have exceptionally high seedling vigor and are highly palatable to livestock. In Kentucky, winter survival can be an issue for many annual ryegrass varieties, so before planting, review winter survival results in this publication. The severe winter of 2013-2014 showed those varieties that are not adapted to Kentucky. Festuloliums are hybrids between various fescues and ryegrasses with higher quality than tall fescue and improved stand survival over perennial ryegrass. Their use in Kentucky is still limited since they do not survive as long as tall fescue but some of the newer varieties are more adapted to Kentucky environmental conditions. This report provides current yield data on annual and perennial ryegrass varieties in trials in Kentucky as well as guidelines for selecting varieties, as well as summaries of all annual and perennial ryegrass and festulolium varieties tested in Kentucky for the last 15 years.

"Fescue toxicosis" is the general term used for the clinical diseases that can affect cattle consuming endophyte-infected tall fescue. Tall-fescue pastures containing ergot alkaloids are responsible for the toxic effects observed in livestock, including hyperthermia (elevated body temperature), gangrene of the extremities, decreased weight gain, and poor reproductive performance. Clinical signs vary depending on the cattle, the environmental conditions, and the level and duration of the exposure. Early clinical signs are often reversible after removal from contaminated pastures or hay.

2012 Long-Term Summary of Kentucky Forage Variety Trials

12/14/2012 (new)
Authors: Garry Lacefield, Gene Olson, Ray Smith

Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past 10 to 12 years.

2012 Alfalfa Grazing Tolerance Report

12/5/2012 (new)
Authors: Joey Clark, Garry Lacefield, Gene Olson, Ray Smith

Alfalfa (Medicago sativa) is the highest-yielding, highest-quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Recent emphasis on its use as a grazing crop and the release of grazing-tolerant varieties have raised the following question: Do varieties differ in tolerance to grazing? We have chosen to use the standard tolerance test recommended by the North American Alfalfa Improvement Conference. This test uses continuous heavy grazing to sort out differences in grazing tolerance in a relatively short period of time.

Authors: Joey Clark, Garry Lacefield, Gene Olson, Ray Smith

Red clover (Trifolium pratense L.) is a high-quality, short-lived perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. Stands of improved varieties are generally productive for two and a half to three years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, high yield, and animal acceptance.

Vegetative Filter Strips for Livestock Facilities

Authors: Steve Higgins, Ray Smith, Sarah Wightman

An enhanced vegetative strip is a best management practice that can be installed to protect surface waters from pollution produced by animal production facilities. Most people think of a vegetative strip as a grassed area or waterway, but when intentionally installed and properly managed, an EVS can be much more effective than a simple grassed filter strip. If properly managed, enhanced vegetative strips can be used to trap, treat, and absorb pollutants, which can be removed from the designated area by harvesting or grazing.

The concept of stockpiling is pretty straightforward, but the challenge each year is to determine the likelihood that this practice will be profitable given the economic and agronomic conditions present at mid-summer. This practice can yield significant benefits, but it also carries significant costs. These benefits and costs must be quantified and compared to assess the overall profitability of the practice.

The choice of variety can impact yield, thickness of stand, and persistence.

2009 Red and White Clover Report

11/24/2009 (new)
Authors: David Ditsch, Garry Lacefield, Gene Olson, Ray Smith, Norm Taylor

Red clover (Trifolium pratense L.) is a high-quality, short-lived, perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. Stands of improved varieties are generally productive for two to three years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, high yield, and animal acceptance.
