Differences between progeny of beef sires in susceptibility to fescue toxicosis
Journal of Animal Science, 1993Fifteen progeny of two Polled Hereford sires were fed endophyte-infected tall fescue seed (E+) to investigate variability in susceptibility to fescue toxicosis. One sire, bred in Missouri, was reputed to produce calves that were resistant to fescue toxicosis. The Control sire, from Virginia, had unknown merit for susceptibility.

Fescue toxicosis and its impact on animal agriculture.
Veterinary and human toxicology, 1993Studies of fescue toxicosis have identified several classes of plant/fungal alkaloids that may be responsible for the toxicosis problem of endophyte (Acremonium coenophialum) infected tall fescue (Festuca arundinacea). This review explores the interaction of these alkaloids with the animal's system and attempts to explain the various anomalies of ...

Fescue Toxicosis Update/Bovine Hysteria from Ammoniated Forages Update
American Association of Bovine Practitioners Conference Proceedings, 1985Fescue toxicity in cattle includes three distinct entities: fescue foot, fat necrosis and summer syndrome. Summer syndrome has a considerably greater economic impact than either of the other disorders. Summer syndrome denotes poor performance by cattle grazing tall fescue, especially notable during hot, humid weather.

Reproductive problems related to fescue toxicosis in mares
1997An outbreak of abortion, agalactia and weak foals was observed in a thorougbred breeding farm in south - central Chile. Of 96 pregnant mares, grazing on tall fescue, 11 aborted and 6 presented agalactia. A high percentage of weak foals was also observed. Acremonium coenophialum was isolated from tall fescue, suggesting that the reproductive ...

A model of fescue toxicosis: responses of rats to intake of endophyte-infected tall fescue.
Journal of animal science, 2007A study was conducted to develop a model for fescue toxicosis using rats fed a diet containing endophyte-infected tall fescue seed (E+). Rats implanted with telemetric transmitters to continuously monitor core body temperature (Tc) and activity were housed at thermoneutrality (21 degrees C) and were fed a diet containing endophyte-free fescue seed (E-).

Genetic variation of susceptibility to fescue toxicosis in cattle
2014Fifteen calves of two sires were fed endophyte infected (E + ) fescue seed to quantify differences in susceptibility to fescue toxicosis among sire groups. One of the sires, a Polled Hereford, had a commercial reputation of producing calves with less severe symptoms of tall fescue toxicosis than their contemporaries.
