Endophyte Infected Tall Fescue: Plant Symbiosis to Animal Toxicosis [PDF]

open access: yesFrontiers 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 ...

Evaluation of Resistance to Fescue Toxicosis in Purebred Angus Cattle Utilizing Animal Performance and Cytokine Response

open access: yesToxins, 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

open access: yesToxins, 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.

Integrative interactomics applied to bovine fescue toxicosis

open access: yesScientific 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 ...

Condensed Tannins Attributes: Potential Solution to Fescue Toxicosis?

open access: yesAgriculture (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.

Identification of Breed Differences in Known and New Fescue Toxicosis Associated Phenotypes in Charolais-and Hereford-Sired Crossbred Beef Cows

open access: yesAnimals, 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.

Fescue toxicosis and its influence on the rumen microbiome: mitigation of production losses through clover isoflavones

open access: yesJournal of Applied Animal Research, 2018
This review highlights concerns with endophyte-infected tall fescue as a primary forage base in the southeastern United States and discusses specific physiological and ruminal effects caused by consumption of ergot alkaloids.

Metagenomic Analysis Revealed Significant Changes in the Beef Cattle Rectum Microbiome Under Fescue Toxicosis

open access: yesBiology
Tall 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.

Urinary Alkaloid Excretion as a Diagnostic Tool for Fescue Toxicosis in Cattle [PDF]

open access: yesJournal 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.

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

open access: yesGrassland 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
