Two trials in the fall and winter of 1997-98 evaluated calf performance when grazing either rye with crop residues or crop residues alone. While not significant, calves grazing rye followed by corn residues tended to gain faster compared to calves grazing residues alone (2.26 versus 1.84 lb/d, respectively). Calves grazing corn residues only fully compensated for the weight difference at the end of winter grazing by slaughter. No differences were found in finishing performance or slaughter breakevens. In trial 2, steers grazed rye and milo or milo residue alone. Steers grazing rye/milo gained faster (P < .05). Using rye to supplement animals on milo residues resulted in steers not leaving the rye portion of the field.
