Relation of Initial Weights and Subsequent Gains of Weanling Calves1

Ellis S. Ruby, C. T. Blunn, E. M. Brouse and Marvel L. Baker

University of Nebraska Agricultural Experiment Station

Abstract

The data in this study of 959 Hereford calves conducted over a winter feeding season and a summer grazing season for 28 seasons support the following conclusions:

  1. On an intra-lot basis, large winter gains were followed by small summer gains, the regression coefficient of summer gain upon winter gain being –0.2a.
  2. A closer relationship existed between contiguous weights and gains than between more widely separated weights and gains.
  3. Correlation values for all relationships studied were highly significant.
  4. The variation in total gain was small, indicating that the variations in winter gains were balanced by variations in the gains made during the subsequent summer gracing season.
  5. Increased winter gains resulted in increased total gain.
