Fig. 1. Winter herbage mass of endophyte-infected Kentucky 31 (KY31 E+), HiMag infected with a nontoxic endophyte (HiMag NTE), and endophyte-free HiMag (HiMag E-) tall fescue. Data are pooled across four winter sampling dates and 2 yr. Bars with the same letter are not significantly different using Fisher's protected LSD ( = 0.05).

Fig. 2. Acid detergent fiber, neutral detergent fiber, and crude protein (CP) of stockpiled tall fescue from mid-December through mid-March of 1999-2000 (Year 1) and 2000-2001 (Year 2). Data are pooled across three entries of tall fescue. Means with the same letter within a year are not significantly different using Fisher's protected LSD ( = 0.05).

Fig. 3. Ergovaline concentration of stockpiled, endophyte-infected Kentucky 31 (KY31 E+) tall fescue from mid-December through mid-March of 1999-2000 (Year 1) and 2000-2001 (Year 2). Means labeled with the same letter within a year are not significantly different using Fisher's protected LSD ( = 0.05).
