Factors influencing transient gene expression in electroporated tall fescue (Festuca arundinacea Schreb.) protoplasts
For the rapid establishment of optimal conditions for a genetic transformation system for tall fescue, several factors influencing transient gene expression were studied in protoplasts, after the reporter β-glucuronidase (GUS) gene was introduced by electroporation. In a time-course study of …

The palatability and nutrient value of tall fescue (Festuca arundinacea Schreb.) forage and evaluation of seven systems of forage finishing beef steers
Most cattlemen in the Southeast are in the cow-calf business and sell calves at weaning. The extra cost of shipping feeder calves for finishing and then shipping the carcasses back to the East adds to the price of meat. This practice also takes away a potential source of profit by farmers who could …

Nitrogen utilization in tall fescue (Festuca arundinacea Schreb.) pastures fertilized with nitrogen or grown with alfalfa (Medicago sativa L.) or red clover (Trifolium pratense L.)
Use of legumes as an alternative to nitrogen (N) fertilization in pasture management improves forage quality and animal performance and has been suggested to reduce the potential for environmental pollution. "Kentucky 3l" tall fescue fertilized with 160 kg N ha-1 yr-1 (split application) was …

The effect of perennial grass species on forage growth and quality, etiolated growth, animal performance and economics
… hybrid bromegrass, and ‘Courtenay’ tall fescue (Festuca arundinacea Schreb.) were seeded. A long established stand of crested wheatgrass acted as the control pasture. For 2003 established pastures, AC Goliath crested wheatgrass (7515 kg ha-1) had greater (P

The effects of irrigation and nitrogen management on water use of tall fescue
Tall fescue (Festuca arundinacea Schreb.) is a commonly cultivated turfgrass in Southern Nevada, one of North America's most arid climates. Recognized for its drought tolerance, tall fescue is nonetheless a significant water user in Southern Nevada. Since outdoor water use represents approximately …

Induction of anti-ergotamine antibodies in mice and steers and protection against fescue toxicosis in mice
Tall fescue (Festuca arundinacea Schreb.) is often infected by the endophytic fungus, Acremonium coenophialum (Morgan-Jones and Gams) The fungus produces ergo peptide alkaloids, especially ergovaline. Consumption of endophyte-infected (ED fescue forage by cattle decreases serum prolactin and …
