Summary and Implications
Fifteen Angus first-calf heifers were evaluated for feed intake utilizing the Feed Intake Monitoring System developed at ISU. Average dry matter intake for the 142- day period was 4718 pounds with over a 3100 pound range in female feed intake. On a daily basis, the low to high spread in daily dry matter intake was 24.7 to 46.6 pounds.
