Introduction Ergot alkaloid toxins produced by Neotyphodium coenophialum in association with tall fescue (Festuca arundinacea) have been shown to affect numerous physiological systems of livestock resulting in decreased profitability of those enterprises. One management technique that has been promoted to reduce the production losses in cattle is crossbreeding (Brown et al., 1997). In addition ...

We examined the effect of endophyte infection level of tall fescue (Festuca arundinacea Schreb.) used for stockpiled forage on the performance of lactating, fallscalving beef cows and their calves. Treatments were endophyte infection levels of 20% (low; SEM = 3.5), 51%, (medium; SEM = 1.25), and 89% (high; SEM = 2.4; 4 replications/treatment). Five cow-calf pairs grazed in each replicate (n = 6...

Johnsongrass is a nonnative invasive species introduced as a forage crop from the Mediterranean region (Miller and Miller 1999). This perennial species has become naturalized and is found in 47 of the 50 United States (Alaska, Minnesota, and Maine being the exceptions) (USDA 2004). Johnsongrass has become problematic along roadsides in Kentucky due to its aggressive and prolific nature and rapi...
