Abstract

Since the introduction of the milk quotas in 1984 Fleckvieh as a dual purpose breed has increased its portion in the German cattle population. The breeding schemes to improve these dual purpose cattle in southern Germany are described with special emphasis on the different testing systems. The selection differential achieved allows a steady improvement in daily gain. The large majority of this progress comes from the selection of test bulls. Very little is known about correlated genetic responses. Depending on the advancements in reproductive technologies the competitivness of dual purpose breeds is briefly discussed.
