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.

Selected Hormonal Changes with Summer Fescue Toxicosis

Journal of Animal Science, 1987
The effects of fescue endophyte content (low, 16 or high, 44% of tillers examined) and of N fertilization rate (low, 134 kg N.ha-1.yr-1 or high, 336 kg N.ha-1.yr-1) upon serum prolactin (PRL) in Angus steers were examined. Jugular blood samples for serum PRL determination were taken before (basal) and after thyrotropin releasing hormone (TRH ...

Alleviating Tall Fescue Toxicosis Problems With Nontoxic Endophytes

American Association of Bovine Practitioners Conference Proceedings, 2000
In 1943, a cultivar of tall fescue (Festuca arundinacea) later known as Kentucky 312 was released for sale. This cool season grass became widely distributed in the southeastern United States because it was persistent in the face of drought, grew on poor ...

Immunosuppression in Cattle with Fescue Toxicosis

1997
Anecdotal observations suggest that cattle entering feed lots after grazing endophyte-infected tall fescue have increased morbidity and mortality (Purdy et al.,1989). The morbidity and mortality has been interpreted as resulting from reduced immune functions in animals with fescue toxicosis.

Efficacy of domperidone and sulpiride as treatments for fescue toxicosis in horses

American Journal of Veterinary Research, 1994
Summary We evaluated the effectiveness of 2 dopamine antagonists as treatments for fescue toxicosis in horses. Sixteen gravid mares were assigned by breed and expected foaling date to 1 of 3 treatment groups; endophyte-infested control; 1.1 mg of domperidone/kg of body weight/d; and 3.3 mg of sulpiride/kg/d.

Abdominal lipomatosis attributed to tall fescue toxicosis in deer

Journal of the American Veterinary Medical Association, 1998
Five adult female Eld's deer died acutely or were euthanatized because of clinical signs including anorexia, signs of depression, and uremia. On necropsy, these deer had large masses of necrotic abdominal fat constricting the ureters, causing hydroureter and hydronephrosis. The herd from which these deer originated was maintained on pastures consisting

Fescue Toxicosis in Horses

1997
Approximately 688,000 horses in the U.S. graze tall fescue (Hoveland, 1993), and for many years, veterinarians and horse owners have reported reproductive problems in mares that consume tall fescue (Garrett et al., 1980; Villahoz et al., 1984; Poppenga et al., 1984). Bacon et al.

A survey concerning the equine fescue toxicosis malady

Journal of Equine Veterinary Science, 1998
Abstract The objective of this research was to determine the scope of equine fescue toxicosis, current procedures to control the disease, and to gain veterinary insight to possible new therapies. A survey was developed with help form experts in the area of fescue toxicosis. From a list of members of the American Veterinary Medical Association (AVMA),

Fungal Populations in the Rumen Associated with Fescue Toxicosis

Journal of Environmental Quality, 1974
AbstractThe fungal population of the rumen of fistulated steers grazing fescue (Festuca arundinacea Schreb.) was studied in 1972 and 1973. Aspergillus terreus Thom was found in 1972 in the rumen shortly after the steers were placed on fescue pastures. Populations of this fungus increased in 6 weeks from 0 to over 1000 propagules per gram of rumen fluid.

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 ...
