Abstract

Six experiments, including five feeding trials, and one 4 x 4 latin square in vivo digestion trial, were conducted to compare the nutritive value of dry corn, ensiled high-moisture corn, ensiled reconstituted high moisture corn and volatile fatty acid treated high moisture corn for growing-finishing beef cattle. In the feeding experiments, cattle made equal gains on from 3 to 13% less dry matter when fed high-moisture corn than when fed dry corn. Improvements in total feed utilization and corn grain utilization were approximately double for the ensiled high-moisture corn and the volatile fatty acid treated high moisture corn over that for the reconstituted high moisture corn. Both the total and corn daily dry matter intake were decreased (4 to 15% total; 4 to 25% corn) by feeding high moisture corn. No improvements in feedlot performance were obtained by feeding rolled dry corn over feeding it whole.

Digestibility of nutrients varied only slightly among the various corn treatments.
