Toxic endophyte-infected tall fescue and range grasses: historic perspectives.

A historic profile of endophyte-induced tall fescue toxicosis is presented. A chronology of events is presented, beginning with the importance of finding Balansia-infected grasses in a tall fescue pasture in north central Georgia. This initial finding was followed by the discovery that another related endophyte was present in tall fescue and other major forage grasses. This species of endophyte...

Ergot Alkaloids Produced by Endophytic Fungi of the Genus Epichloë

The development of fungal endophytes of the genus Epichloë in grasses results in the production of different groups of alkaloids, whose mechanism and biological spectrum of toxicity can differ considerably. Ergot alkaloids, when present in endophyte-infected tall fescue, are responsible for "fescue toxicosis" in livestock, whereas indole-diterpene alkaloids, when present in endophyte-infected r...

Effects of selected endophyte and tall fescue cultivar combinations on steer grazing performance, indicators of fescue toxicosis, feedlot performance, and carcass traits.

Five tall fescue [Lolium arundinaceum (Schreb.)] pastures [wild-type 'Kentucky-31' with 78.0% of plants infected with ergot alkaloid-producing endophyte Neotyphodium coenophialum (KY31 E+), 'Jesup' AR542 endophyte-infected contaminated with 30.3% tall fescue containing ergot alkaloid producing-endophyte (Jesup AR542 E+); 'GA-186' AR584 endophyte-infected contaminated with 11.8% tall fescue cont...

Economic Analysis of Replacing Endophyte-Infected with Endophyte-Free Tall Fescue Pastures

lengthened gestation terms (Waller and Fribourg, 2002; Hemken et al., 1979). The U.S. economic loss in beef Cattle (Bos taurus) consuming tall fescue pastures infected with the associated with this endophyte was estimated at over endophyte Neotyphodium coenophialum often suffer physiological disorders that reduce animal performance. One solution is to replace $600 million annually (Hoveland, 19...
