Beef cattle that respond differently to fescue toxicosis have distinct gastrointestinal tract microbiota. [PDF]
PLoS ONE, 2020 Tall fescue (Lolium arundinaceum) is a widely used forage grass which shares a symbiosis with the endophytic fungus Epichloë coenophiala. The endophyte produces an alkaloid toxin that provides herbivory, heat and drought resistance to the grass, but can ...

The bull sperm microRNAome and the effect of fescue toxicosis on sperm microRNA expression. [PDF]
PLoS ONE, 2014 Tall fescue [Schedonorus phoenix (Scop.) Holub] accounts for nearly 16 million hectares of pasture in the Southeastern and Mid-Atlantic U.S. due to its heat, drought, and pest resistance, conferred to the plant by its symbiotic relationship with the ...

Effects of Sericea Lespedeza Supplementation on Steers Grazing Wild-Type Endophyte-Infected Tall Fescue [PDF]
AnimalsCondensed tannins (CTs) in certain leguminous forages can mitigate toxic alkaloid absorption linked to fescue toxicosis due to their high affinity towards various steroidal and protein-like alkaloids.

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