Description
INTRODUCTION Tall fescue (Festuca arundinacea Schreb), grown on over 14 million ha, is the most common pasture grass in humid areas of the eastern USA and, to limited extent, in the northwestern USA. The presence of an endophyte in tall fescue has been associated with a number of animal health problems including reduced performance (Stuedemann and Hoveland, 1988). Intake was reduced in diets containing the endophyte in seed, hay or green forage (Hemken et al., 1979; Schmidt et al., 1982). However, no studies have been reported which used direct methods to determine intake differences of grazing animals as influenced by the endophyte and if a residual response might exist. The present study was conducted to determine the effect of O and 100 percent (%) endophyte levels in tall fescue pastures on intake of grazing steers and the intake response following exchange from O to 100 % infected pastures and vice versa.
