Differents methods of evaluating the economical value of traits under selection are reviewed : statistical analysis of breeder's profits, simple efficiency models for one animal or one dam-progeny unit, complex models describing the herd as a system. For each of these methods, we discuss the meaning of the economic weighting obtained. We assume that the selection goal is to maximize decider profit.
