Warming reduces tall fescue abundance but stimulates toxic alkaloid concentrations in transition zone pastures of the U.S. [PDF]

Frontiers in Chemistry, 2014
Tall fescue pastures cover extensive acreage in the eastern half of the United States and contribute to important ecosystem services, including the provisioning of forage for grazing livestock.

The Dark Side of Grasslands: Endophyte Toxicosis in Horses—Exposure Risks, Health Consequences, and Management [PDF]

Toxins
Grasslands are the cornerstone of horse feeding, used for grazing and to produce roughages and their products. However, improper grassland management hides several threats for equine health.

Microbiome Responses of Beef Steers to Rotational Grazing of Toxic Endophyte-Infected Tall Fescue Under Fall Conditions [PDF]

Animals
Fescue toxicosis results from ingestion of tall fescue infected with the ergot alkaloid (EA)-producing endophyte Epichloë coenophiala. The gastrointestinal microbiota is the first point of interaction with EAs and may be modulated by them. To investigate

Epichloë—the obligate mutualist protecting some commercially important temperate grasses from biotic and abiotic stresses [PDF]

Frontiers in Microbiology
The relationship between Epichloë fungal endophytes found in some temperate grasses spans the continuum from antagonistic to mutualistic. The predominant focus here is on those that form mutualistic associations with those temperate grasses of the New ...

Metabolomic shifts in beef steers rotationally grazing toxic endophyte-infected tall fescue under fall conditions [PDF]

Frontiers in Veterinary Science
BackgroundFescue toxicosis (FT) results from ingestion of tall fescue infected with the ergot alkaloid (EA)-producing endophyte Epichloë coenophiala. While the vascular system is a major EA target, their biogenic amine-like properties can trigger wider ...

Impact of Low-Level Ergot Alkaloids and Endophyte Presence in Tall Fescue Grass on the Metabolome and Microbiome of Fall-Grazing Steers [PDF]

Toxins
Fescue toxicosis (FT) is a mycotoxin-related disease caused by the ingestion of tall fescue, naturally infected with the ergot alkaloid (EA)-producing endophyte Epichloë coenophiala.

Recovery of Yearling Calves from Fescue Toxicosis [PDF]

, 2023
Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) is widely utilized for grazing in the transition zone between the temperate and subtropical regions of the eastern U.S.A. Cattle grazing tall fescue frequently exhibit fescue toxicosis, a malady

Determining the earliest growth stage to detect the presence of endophytes in tall fescue and perennial ryegrass seedlings using molecular markers

Grassland Research, Volume 2, Issue 2, Page 106-111, June 2023., 2023
Many forage grasses have a beneficial fungus living inside them. The presence of this fungus is a necessity to many producers. Knowing when and how to test for it has been a problem in the past. Here, we compare different methods of fungal testing and different time points that will help producers make testing decisions. Abstract Background Tall fescue
