1.  IVDMD (in vitro dry matter disappearance) is an indicator of quality and is positively related to animal
     digestibility (higher values indicate higher digestibility).  Samples used for IVDMD determination were
     collected for all entries of a replicated trial at the same state of reproductive development (soft dough).
2.  CV = 10.3% and df for EMS = 24.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
