This thesis gives the results of a study on the relationship between cattle breeding goals and production circumstances. The relationship between breeding goals and production circumstances mostly arises from the influences of production circumstances on the economic values of geneticimprovement of animal traits. The economic value of a trait expresses to what extent economic efficiency of production is improved at the moment of expression of one unit genetic uperiority of that trait. Economic values are used in defining the breeding goal (to aggregate genotypes for several traits to a so called 'aggregate genotype') and also in calculating economic revenues of breeding programmes (to value predicted genetic superiorities).The objects of th...
