- ... During winter 5 varieties of tall fescue (Festuca arundinacea) were grazed by steers and evaluated for their fescue foot toxicity potential. In order of their relative toxicity, the varieties were KY-31, Kenhy, Mo-96, Kenmont and Fawn. Ky-31 was the most toxic in 2 or 3 annual grazing experiments. Kenhy, Mo-96 and Kenmont were intermediate in toxicity as estimated by observations of knuckling, lam ...

- ... The specific compound(s) that produces fescue foot in cattle grazing tall fescue (Festuca arundinacea) remains unidentified. The study further defines the chemical nature of the toxicant(s) within the anion fraction on an 80% ethanolic extract of toxic tall fescue. By combining the bovine intraperitoneal (ip) assay with videothermometry and ion exchange chromatography, and gas chromatography with ...
