Treatments included two weaning dates, October (OCT) and December (DEC), and four winter nutritional treatments, grazing winter range with no supplement (WR0), low supplement (WR1), high supplement (WR2); or grazing corn residue with no supplement (CR) applied in a 2 × 4 factorial arrangement. Net returns at the December weaning date were greatest ( < 0.
