apdDM – potentially digestible forage dry matter; OM – organic matter; CP – crude protein; NDIN – neutral detergent insoluble N; apNDF – neutral detergent fiber corrected for ash and protein residue; iNDF – indigestible neutral detergent fiber

bpdDM was estimated for forage sampled in the area delimited by a metal square 0.5 m × 0.5 m; chemical composition was evaluated in the hand-plucked forage sample
