Abstract

A problem of great significance in an up-to-data breeding of the dual-purpose cattle is an estimation of a possible genetic gain and the factors influencing the expected progress as well as the extent of their action. Numerous studies devoted to this problem indicate that a wide use of artificial insemination together with a well-designed breeding program are expected to bring an annual genetic gain in milk recording reaching 2 % of an average performance in a population under Improvement Progra
