Fig. 4. Trends in (a) neutral detergent fiber (NDF) and (b) in vitro true digestibility (IVTD) for endophyte-free (Ky31e-) and endophyte-infected (Ky31e+) tall fescue across five water levels (WLs). The difference between cultivars was significant (P < 0.05) only at WL-3 for NDF [LSD_(0.05) = 7.8 g kg^-1]. Differences between cultivars were significant at WL-2 [LSD_(0.05) = 5.4 g kg^-1] and WL-3 [LSD_(0.05) = 4.9 g kg^-1].
