Relationships among Ergot Alkaloids, Cytochrome P450 Activity, and Beef Steer Growth

Frontiers in Chemistry, 2015
Determining a grazing animal’s susceptibility to ergot alkaloids has been a research topic for decades. Our objective was to determine if the Promega™ P450-Glo assay could be used to indirectly detect ergot alkaloids or their metabolites in urine of ...

Abdominal Fat Necrosis in a Pygmy Goat Associated with Fescue Toxicosis [PDF]

Journal of Veterinary Diagnostic Investigation, 2004
Abdominal fat necrosis was diagnosed in an 11-year-old female pygmy goat with a 10-day history of lethargy, anorexia, and progressive abdominal distension. Gross necropsy findings revealed multiple firm, dark yellow, nodular masses of fat throughout the abdominal cavity, which compressed several abdominal organs including the rumen, small intestine ...

Acute exposure to ergot alkaloids from endophyte-infected tall fescue does not alter absorptive or barrier function of the isolated bovine ruminal epithelium*

Animal, 2014
Ergot alkaloids in endophyte-infected (Neotyphodium coenophialum) tall fescue (Lolium arundinaceum) have been shown to cause a reduction in blood flow to the rumen epithelium as well as a decrease in volatile fatty acids (VFA) absorption from the washed ...

Evaluation of Electrocution for Weed Control and Tall Fescue Seedhead Reduction in Missouri Pastures

Weed Technology
Despite its efficacy, little research has been conducted to evaluate the potential for electrocution to control common weeds in pastures. Electrocution could also potentially be utilized as a management tool to minimize the production of tall fescue ...

Hepatic transcript profiling in beef cattle: Effects of feeding endophyte-infected tall fescue seeds.

PLoS ONE
The objective of our study was to evaluate the effect of endophyte-infected tall fescue (E+) seeds intake on liver tissue transcriptome in growing Angus × Simmental steers and heifers through RNA-seq analysis.

The Effects of Endophyte-Infected Tall Fescue on the Production and Reproductive Performance Parameters of Beef Cattle and Calves

Grasses
Records from 2012 to 2019 for two herds were analyzed to determine how tall fescue (Schedonorus arundinaceus (Schreb.) Dumont) endophyte (Epichloë coenophialum) status affected the productivity of spring-calving cows and calves. Pastures either contained

Characterization of Epichloë coenophiala within the U.S.: are all tall fescue endophytes created equal?

Frontiers in Chemistry, 2014
Tall fescue (Lolium arundinaceum) is a valuable and broadly adapted forage grass that occupies approximately 14 million hectares across the United States. A native to Europe, tall fescue was likely introduced into the U.S. around the late 1800’s. Much of
