Fig. 1. Condensed tannin concentration expressed as catechin equivalents (CE) in grazed birdsfoot trefoil in 1998. Pastures included ‘Norcen’ birdsfoot trefoil (BFT) and rhizomatous birdsfoot trefoil (RBFT) grown in monocultures and mixtures with tall fescue (TF). Means with similar letter are not different at 0.05 {alpha} level. *Condensed tannin of BFT in monoculture differed from BFT in mixtures at 0.10 {alpha} level.
