Interpretive Summary:

Technical Abstract: This publication constitutes the Forage-Animal Production Research Unit’s annual report to the SERA-IEG 8 Tall Fescue Toxicosis/Endophyte Workshop group held at the Natchez Trace State Park, Pin Oak Lodge, Wildersville, TN on October 14-16, 2007. The Unit present updates and answered questions on the following research projects: 1.) Microarray and real-time PCR comparisons of tall fescue gene expression in endophyte-infected and endophyte-free plants; 2.) Blood flow characteristics of heifers exposed to varying levels of ergot alkaloids; 3.) Effects of feeding heat stressed steers non- and endophyte infected tall fescue seed on the contractility of bovine lateral saphenous vein; 4.) Improvements on our LC/MS method for alkaloid analysis; and 5.) Vasoactivity of selected ergot alkaloids.
