2019 Timothy and Kentucky Bluegrass Report

3/2/2020 (new)
Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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. 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.

2019 Long-Term Summary of Kentucky Forage Variety Trials

12/18/2019 (new)
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 12 to 15 years.

12/12/2019 (new)
Authors: Bill Bruening, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

Summer annual grasses provide an important forage crop option for producers in Kentucky. These grasses are mainly used as emergency or supplemental hay and pasture crops, but little information is available on their yield potential. The purpose of this publication is to summarize the University of Kentucky 2013-2019 forage yield trials with sudangrass, sorghum/sudangrass, millets, teff, and cereal crops. Cool season annual grasses (specifically cereal crops) are also used as forages crops for hay, baleage or grazing. The cereal crops used in this report are wheat (Triticum aestivum), rye (Secale cereale), oats (Avena sativa) and triticale (Triticum secale).

2019 Alfalfa Grazing Tolerance Report

12/4/2019 (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? 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.

2019 Red and White Clover Grazing Tolerance Report

12/4/2019 (new)
Authors: Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch

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, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. 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.

2019 Orchardgrass Report

11/27/2019 (new)
Authors: Jimmy Henning, 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. This report provides current yield data on orchardgrass varieties included in yield trials in Kentucky as well as guidelines for selecting orchardgrass varieties.

2019 Annual and Perennial Ryegrass and Festulolium Report

11/27/2019 (new)
Authors: Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch

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. Perennial ryegrass can be used as a short-lived hay or pasture plant and has growth characteristics similar to tall fescue. Festuloliums are hybrids between various fescues and ryegrasses with higher quality than tall fescue and improved stand survival over perennial ryegrass.

2019 Tall Fescue and Bromegrass Report

11/26/2019 (new)
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

Baleage: Frequently Asked Questions

3/5/2018 (new)
Authors: Mike Collins, Dennis Hancock, Jimmy Henning, Brandon Sears, Ray Smith, Chris Teutsch

Baled silage, or "baleage", is an excellent method for forage harvest, storage and feed efficiency. Baled silage allows forage to be harvested at higher whole plant moisture levels than required for dry hay. Baleage is ideal for spring cuttings of annual and perennial forages when seasonally frequent rainfall events provide little opportunity for properly curing dry hay. Many producers who want to harvest high quality small grain crops have found baleage to be a good fit for their operation.

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

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.

Foxtail millet (German millet) is a fine-stemmed summer annual used mainly for emergency hay or pasture for cattle. It is the lowest yielding of the summer annual grasses since it will not regrow after cutting. It can also be used as a smoother crop when transitioning to other perennial forage crops. Foxtail millet is also commonly used for wildlife plantings to produce food and cover for doves, quail, and other birds.

Sudangrass and Sorghum-sudangrass Hybrids

2/19/2018 (new)
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.

2017 Red and White Clover Grazing Tolerance Report

12/11/2017 (new)
Authors: Joey Clark, Gene Olson, Ray Smith, Chris Teutsch

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.

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.

2016 Long-Term Summary of Kentucky Forage Variety Trials

12/12/2016 (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.

2016 Timothy and Kentucky Bluegrass Report

12/5/2016 (new)
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: 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.

Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is welladapted 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. This report provides current yield data on orchardgrass varieties included in yield trials in Kentucky as well as guidelines for selecting orchardgrass varieties.

2014 Long-Term Summary of Kentucky Forage Variety Trials

12/10/2014 (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.

Fescue Toxicosis

7/3/2014 (new)
Authors: Michelle Arnold, Cynthia Gaskill, Ray Smith

"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.

Cyanide poisoning of livestock is commonly associated with johnsongrass, sorghum-sudangrass, and other forage sorghums. Choke-cherry or wild cherry, elderberry, and arrow grass are less frequent causes. Young plants, new shoots, and regrowth of plants after cutting often contain the highest levels of cyanogenic glycosides. The risk from potentially dangerous forages may be reduced by following the management practices in this publication.

Forage-Related Disorders in Cattle: Nitrate Poisoning

3/10/2014 (new)
Authors: Michelle Arnold, Cynthia Gaskill, Jeff Lehmkuhler, Ray Smith

Few plants normally contain high nitrate levels, since under normal growing conditions the nitrates are converted to protein as quickly as they are absorbed from the roots. However, under certain conditions plants can develop dangerously high nitrate levels which can cause nitrate intoxication. Death or abortion may result. Care must be taken to recognize possible toxic forages and manage them appropriately to avoid animal loss.

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 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.

It has been investigated as a renewable energy crop due to its high productivity across a wide geographic range including various environmental conditions and soil types. Switchgrass has also been used for erosion control, summer grazing in pasture and hay systems for cattle, native prairie restoration, wildlife habitat, fiber production, and as an ornamental grass.

Vegetative Filter Strips for Livestock Facilities

2/23/2012 (new)
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.

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.

(reprinted)
Authors: Greg Halich, Jeff Lehmkuhler, Lee Meyer, Gregg Rentfrow, Ray Smith
