Baleage: Frequently Asked Questions
3/5/2018 (new)

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. | AGR-235

Warm Season Annual Grasses in Kentucky
3/5/2018 (new)

In Kentucky, cool-season grasses produce ample forage in the spring and fall, but high temperatures and short-term drought stress often limits growth during the summer months. Warm-season annual grasses can fill this gap with relatively high quality forage when properly managed. The purpose of this publication is to provide an overview of the various summer annuals for Kentucky. | AGR-229

Sudangrass and Sorghum-sudangrass Hybrids
2/19/2018 (new)

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. | AGR-234

Foxtail Millet
2/19/2018 (new)

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. | AGR-233

Crabgrass
2/19/2018 (new)

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. | AGR-232

Pearl Millet
2/19/2018 (new)

The primary benefits of pearl millet are that it does not contain prussic acid and is not susceptible to the sugarcane aphid. Dwarf varieties are available, which are leafier and better suited for grazing. | AGR-231
web only | 2 pages | 681 words | 7 downloads | PDF: 1,183 kb

Forage Sorghum
2/19/2018 (new)

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. | AGR-230

2017 Alfalfa Grazing Tolerance Report
12/11/2017 (new)

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.

Pastured Poultry
9/21/2017 (new)

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. | ID-247

Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands
4/10/2017 (minor revision)

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. | PPA-30

2016 Annual and Perennial Ryegrass and Festulolium Report
12/5/2016 (new)

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. | PR-714

2016 Timothy and Kentucky Bluegrass Report
12/5/2016 (new)

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. | PR-713

12/10/2015 (new)

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. | PR-698

2015 Annual and Perennial Ryegrass and Festulolium Report
12/8/2015 (new)

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. | PR-699

2015 Tall Fescue and Bromegrass Report
12/8/2015 (new)

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. | PR-697

Fescue Toxicosis
7/3/2014 (new)

"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. | ID-221

2011 Red and White Clover Report
12/19/2011 (new)

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. | PR-628

Profitability of Nitrogen Applications for Stockpiling Tall Fescue Pastures: 2011 Guide
10/5/2011 (new)

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. | ID-193

2010 Alfalfa Grazing Tolerance Report
12/15/2010 (new)

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. | PR-615
