Abstract
Title of the paper: An approach to quantify management differences bet ween cattle breeding programs It was attempted to derive objective cri teria to evaluate the efficiency of dairy cattle breeding programs in Germany. Based on the 'top-50-sire list' for four years different vari ables were calculated, Lire the total number of top-50-placements, the number of top-ranked bulls and the average ranking of those bulls. If set in relation to the active population size, these figures allow a differentiated validation of the strenghts and weeknesses of the breed ing programs. In addition to the tools suggested an efficient controll ing of the breeding programs requires further criteria quantifying the performance on the genetic and economic scale.
