Digestibility of tall fescue at various growth stages was measured during 2 successive years. OM digestibility was 71% during early growth, falling to 62% at heading. Energy values were 0.67 and 0.57 F.U./kg DM during early growth and at heading, respectively, during the 1st year; corresponding values for the 2nd year were 0.67 and 0.62. Comparative values for DCP content were 140 and 71 g/kg DM in the 1st year and 90 and 50 g in the 2nd year.
