Evaluation of Resistance to Fescue Toxicosis in Purebred Angus Cattle Utilizing Animal Performance and Cytokine Response [PDF]
Toxins, 2020 Fescue toxicosis is a multifaceted syndrome common in cattle grazing endophyte-infected tall fescue; however, varying symptomatic responses potentially imply genetic tolerance to the syndrome.

Use of Integrative Interactomics for Improvement of Farm Animal Health and Welfare: An Example with Fescue Toxicosis [PDF]
Toxins, 2020 Rapid scientific advances are increasing our understanding of the way complex biological interactions integrate to maintain homeostatic balance and how seemingly small, localized perturbations can lead to systemic effects.

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.

Condensed Tannins Attributes: Potential Solution to Fescue Toxicosis?
Agriculture (Switzerland), 2023 Tall fescue (Schedonorus arundinaceous (Schreb.) Dumort. nom. cons. Lolium arundinaceum (Schreb.) Darbysh.) toxicosis results from the consumption of alkaloids released by wild-type endophytes (Epichloe coenophiala) that live in symbiosis with the plant.

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 ...

Integrative interactomics applied to bovine fescue toxicosis [PDF]
Scientific Reports, 2022 Bovine fescue toxicosis (FT) is caused by grazing ergot alkaloid-producing endophyte (Epichloë coenophiala)-infected tall fescue. Endophyte’s effects on the animal’s microbiota and metabolism were investigated recently, but its effects in planta or on ...

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 ...

Urinary Alkaloid Excretion as a Diagnostic Tool for Fescue Toxicosis in Cattle [PDF]
Journal of Veterinary Diagnostic Investigation, 2000 Fescue toxicosis research studies have often included serum prolactin as a physiologic index of the disorder. Serum prolactin has not been used as a clinical measure of fescue toxicosis because of variation associated with sex and physiologic condition of the animal and climatic and seasonal factors.

Endophyte Infected Tall Fescue: Plant Symbiosis to Animal Toxicosis [PDF]
Frontiers in Veterinary Science, 2021 Endophyte-infected fescue is a major cool season forage used for livestock production in the United States and through other areas of the world. A unique aspect of this forage resource is the symbiotic relationship with an endophytic fungus (Epichloë ...
