Abstract

Three finishing trials were conducted to determine effect of corn processing on degradable intake protein requirement of feedlot cattle. Finishing diets consisted of 82% processed corn which was either dry rolled, high moisture, or steam flaked. Degradable intake protein levels were achieved by adding 0 to 2.0% urea (DM basis) to the control diets. Estimates of degradable intake protein requirement for a dry-rolled corn-based diet were approximately 6.3% of dietary DM. Degradable intake protein requirement for high-moisture corn-based diets was approximately 10% of dietary DM. Degradable intake protein requirement for steam-flaked corn-based diet was between 7 and 9.5% of dietary DM.
