Identification of Breed Differences in Known and New Fescue Toxicosis Associated Phenotypes in Charolais-and Hereford-Sired Crossbred Beef Cows [PDF]
Animals, 2021 Beef cattle phenotypes are affected by the consumption of toxic fescue. Toxic fescue’s impact is dependent on heat stress and breed composition, with genetic variability for robustness to toxin exposure believed to exist within and across breeds.

Metagenomic Analysis Revealed Significant Changes in the Beef Cattle Rectum Microbiome Under Fescue Toxicosis [PDF]
BiologyTall fescue toxicosis, caused by ingestion of endophyte-infected tall fescue (Lolium arundinaceum), impairs growth and reproduction in beef cattle and results in over USD 3 billion annual loss to the U.S. livestock industry.

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 ...

PSXVI-27 Using tannin to mitigate tall fescue toxicosis [PDF]
Journal of Animal Science, 2021 Abstract Fescue toxicosis has a negative impact on livestock production. Tannins could bind to tall fescue toxins rendering them ineffective. The objective was to improve health and well-being of sheep offered tall fescue infected with the endophytic fungus (Neotyphodium coenophialum) by binding toxins in the rumen with condensed tannins.

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.

Non-Invasive Techniques Reveal Heifer Response to Fescue Endophyte Type in Grazing Studies [PDF]
Animals, 2023 Cattle grazing tall fescue (Schedonorus arundinaceous) infected with wild-type endophytes (WE) leads to a syndrome commonly known as fescue toxicosis. Replacing WE tall fescue with a novel endophyte-infected (NE) tall fescue can mitigate this problem but

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.
