Regional differences in the fescue toxicosis response of Bos taurus cattle

International Journal of Biometeorology, 2014
Cattle of the same breed from different regions of the USA may have altered responses to heat stress and fescue toxicosis. Angus steers from Missouri (MO ANG, n = 10, 513.6 ± 13.6 kg BW) and Oklahoma (OK ANG, n = 10, 552.8 ± 12.0 kg BW) were fed a diet containing either endophyte-infected (E+, 30 μg ergovaline/kg BW/day) or endophyte-uninfected (E-, 0 ...

Pathophysiology of fescue toxicosis

Agriculture, Ecosystems & Environment, 1993
Abstract The pathophysiology of fescue toxicosis is discussed relative to observed symptoms and the inhibition of animal production (average daily gain and decreased reproductive efficiency). Hyperthermia, vasoconstriction and perhaps increased activity of hepatic mixed-function oxidases are important effects. Perhaps secondarily intake is reduced by

Effects of fescue toxicosis on reproduction in livestock

Journal of Animal Science, 1992
Fescue toxicosis in livestock is due to ingestion of endophyte (Acremonium coenophialum) -infected tall fescue. Understanding mechanisms responsible for decreased calving and growth rates, delayed onset of puberty, and impaired function of corpora lutea in heifers at puberty consuming endophyte-infected fescue is an emerging field in reproductive ...

Equine fescue toxicosis: signs and solutions

Journal of Animal Science, 1995
Gravid mares grazing endophyte-infested (E+) tall fescue exhibit increased gestation lengths, agalactia, foal and mare mortality, tough and thickened placentas, weak and dysmature foals, increased sweating during warm weather, reduced serum prolactin and progesterone, and increased serum estradiol-17 beta levels.

Diagnostic Tool for Fescue Toxicosis

American Association of Bovine Practitioners Conference Proceedings, 1997
Fescue toxicosis is the result of grazing endophyte (Neotyphodium coenophialum) infected tall fescue (Festuca arundinacea). Most tall fescue pastures are endophyte-infected (E+) and this results in the presence of ergot alkaloids in the forage. As a result of these alkaloids in E+, rate of gain and calving rates are decreased (Stuedemann and Hoveland ...

Tall Fescue Toxicosis and Management

Crop Management, 2004
Tall fescue toxicosis is one of the most costly animal disorders facing livestock producers in the eastern U.S. As reported by Georgia researchers in 1977, it is caused by a fungal endophyte. At present, there is no cure for tall fescue toxicosis. There are, however, proven management strategies that can lessen the effect of toxicosis.

Fescue toxicosis

Veterinary Clinics of North America: Equine Practice, 2001
Most of the tall fescue pastures in the United States are infected by an endophyte, N. coenophialum. The fungus derives nutrients from the plant while supplying the plant with toxins for defense. The most detrimental toxins for animals in tall fescue are ergopeptine alkaloids, especially ergovaline.

The effects of fescue toxicosis on beef cattle productivity

Journal of Animal Science, 1995
Consumption of tall fescue forage infested with the endophytic fungus Acremonium coenophialum can result in a condition termed "fescue toxicosis," which is characterized by decreased weight gains, milk production, conception, and serum prolactin and an inability to dissipate body heat by beef cattle.
