Possible Fescue Toxicosis in Incoming Feeder Cattle

American Association of Bovine Practitioners Conference Proceedings, 1985
Cattle are received into feedyards in the Southwest from nearly all parts of the nation, including groups off of summer fescue pastures. This paper presents a case of epidemic heat stroke in several groups of cattle received during June from summer fescue pastures known to be infected with the endopytic fungus Epichloe typhina ( Acremonium coenophialum)

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),

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 soils and provided good erosion control, as well as large amounts of forage for hay or grazing.2 By ...

Alteration of fasting heat production during fescue toxicosis in Holstein steers

Journal of Animal Science, 2013
This study was designed to examine alteration of fasting heat production (FHP) during fescue toxicosis. Six ruminally cannulated Holstein steers (BW = 348 ± 13 kg) were BW-matched into pairs and used in a 2 period crossover design experiment. Each period consisted of 2 temperature segments, one each at 22 and 30°C.

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 ...

Field Studies on Etiology and Control of Fescue Toxicosis

Journal of Environmental Quality, 1975
AbstractAn outbreak of fescue toxicosis occurred in cattle in the southern part of Mississippi in 1969–70. A survey of veterinarians and county agents revealed that fescue toxicosis occurred in 15 Mississippi counties, with general distribution across the state.

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.

Fescue Toxicosis in Commercial Cattle Feeding Operations

American Association of Bovine Practitioners Conference Proceedings, 1986
Tall Fescue (Festuca Arundinacea Schreb.) accounts for approximately 35 million acres of grassland in the U.S. Fescue pastures continue to be a major cattle grazing staple in the transition zone of the U.S. including the south central regions of the country.

Immunologic and Other Strategies to Overcoine Fescue Toxicosis

American Association of Bovine Practitioners Conference Proceedings, 1995
Tall fescue has desirable compositional characteristics, withstands heavy grazing and environmental stresses. However, animal performance (body weight gains and reproductive efficiency) is depressed in animals grazing this forage. The signs exhibited by affected animals are exacerbated by elevated environmental temperatures and humidity.
