Abstract

Attention is drawn to some applications of selection theory in animal breeding which seem important for further genetic improvements in animal production. The central objective is assumed to be genetic improvement in net bio-economic efficiency, including all important components of performance in the life cycle, weighted by their effects on production costs per unit of animal product value. These weightings may differ with regional or other variation in production systems and market preferences and would differ for breeds to be used primarily as male, female, or as both, in commercial crossbreeding.
