Individual Feeding in Steer Experimentation

University of Minnesota

Abstract

More and more, attention is being focused upon economy of production. It, therefore, is but natural that effort should be directed toward finding out what inherent differences exist between animals in their economy of meat production.

Object of This Study

The object of this study was to make individual comparisons of feed consumption and economy of gains between steers of the same age and market class and grade. If this study revealed individual differences of sufficient magnitude to be of practical importance, these trials would then be followed with an effort to develop a practical Record of Performance for beef cattle.

Plan of Experiment

Nine yearling grade Shorthorn steers, grading "good feeders," were secured from the South St. Paul market. No attempt was made to secure steers which were identical in phenotype, but rather to secure steers with enough differences in phenotype to be a fair sampling of this market grade and class. Ten other yearlings of the same market grade and class were secured to be fed in a group.
