ID-186: Managing Legume Induced Bloat in Cattle
Michelle Arnold, Roy Burris, David Ditsch, Garry Lacefield, Jeff Lehmkuhler | Mar. 10, 2011 (New)
Ruminal tympany, or bloat, can result in lost animal performance and in severe cases, death. It occurs as a result of a buildup of fermentation gases in the rumen. Bloat may be categorized as frothy bloat, which is caused by the formation of a stable foam in the rumen, or free gas bloat, which is due to excessive production of gaseous compounds from fermentation or as a result of an obstruction preventing the escape of gas compounds. Legume bloat is a frothy bloat condition.
ID-74: Planning Fencing Systems for Intensive Grazing Management
Curtis Absher, Ken Evans, Larry Turner | Feb. 16, 2011 (Reprinted)
PR-620: 2010 Long-Term Summary of Kentucky Forage Variety Trials
Garry Lacefield, Gene Olson, Ray Smith | Jan. 5, 2011 (New)
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.
PR-618: 2010 Cool-Season Grass Horse Grazing Tolerance Report
Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith | Jan. 3, 2011 (New)
Cool-season grasses such as bluegrass, tall fescue, and orchardgrass are dominant pasture grasses for horses in Kentucky. Variety evaluations for yield have been carried out for many years, but little work has been done to establish the effect of variety on persistence when subjected to close, continuous grazing by horses.
PR-619: 2010 Summer Annual Grass Report
Garry Lacefield, Gene Olson, Ray Smith | Jan. 3, 2011 (New)
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 2007-2010 forage yield trials with sudangrass, sorghum/sudangrass, millets, and teff.
PR-617: 2010 Cool-Season Grass Grazing Tolerance Report
Gene Olson, Tim Phillips, Ray Smith, Eric Vanzant | Jan. 3, 2011 (New)
Cool-season grasses such as tall fescue and orchardgrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and prairie brome can be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species.
PR-616: 2010 Red and White Clover Grazing Tolerance Report
Garry Lacefield, Gene Olson, Ray Smith, Eric Vanzant | Dec. 15, 2010 (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-614: 2010 Timothy and Kentucky Bluegrass Report
Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Dec. 15, 2010 (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 can be used for grazing or wildlife habitat.
PR-615: 2010 Alfalfa Grazing Tolerance Report
Garry Lacefield, Gene Olson, Ray Smith, Eric Vanzant | Dec. 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-610: 2010 Red and White Clover Report
David Ditsch, Garry Lacefield, Gene Olson, Ray Smith | Dec. 6, 2010 (New)
