The intent of this report is to provide highlights of our research and extension activities. We have a vested interest in the beef industry in the state and nation, and hope this report provides a window into our programs. We believe that after viewing this report, a greater appreciation will be garnered with respect to our involvement in the multiple fields of study related to beef production. The faculty, staff and student activities are advancing our understanding of basic science principles of livestock production as well as applied research that producers and the industry can benefit from immediately, as well as in the future. Extension educational programs, on-farm demonstrations, and other activities aid in transferring this knowledge to producers, allowing for increased awareness and adoption of management change.

The 2010 Research and Extension Beef Report highlights advances in understanding of basic scientific principles of livestock production as well as applied research from which producers and the industry can benefit. Extension educational programs, on-farm demonstrations, and other activities help transfer this knowledge to producers so they can adopt of management changes as appropriate.
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.
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.
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.
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. The main focus will be on plant stand survival.
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.
Red clover (Trifolium pratense) and white clover (Trifolium repens) are both high-quality forage legumes that are used primarily in mixed stands with tall fescue or orchardgrass for improving yield and quality of pastures.
