High moisture corn harvested at 18 and 26% moisture, rolled, treated with
0, .75, 1.5, or 2.25% urea (DM basis), and ensiled was evaluated for fermentation
rate, chemical composition, and aerobic stability. Adding urea to 26% moisture
corn increased the rate and extent of fermentation as measured by lactic, acetic,
and total acid concentrations. Only a very limited fermentation occurred in the
18% moisture corn. No statistically significant differences were noted in DM loss
or aerobic stability among the eight corn treatments.
