Abstract

Analyses at both the herd and individual heifer level were considered necessary to understanding replacement heifer performance and both will be reported in this introductory paper. In particular, a study of the role of weaning weight and yearling weight as a determinant of beef heifer productivity was a major part of the project. A description of the selection, breeding, and calving strategies employed by managers and the calculation of monitors of replacement heifer production from breeding to weaning of their first progeny should provide useful comparisons for Ontario farmers and their advisors.
