Growth and carcass parameters of fattening bulls of the German Fleckvieh [German Simmental] and German Holstein breeds were examined. The animals (n = 113) were slaughtered, dissected and investigated at birth or 6, 12, 18 or 24 months of age. German Simmental calves weighted 48.8 kg and were 10 kg heavier at birth and grew more intensively to 18 and 24 month of age; they had weights of 672.1 kg, compared with 570.4 kg for German Holsteins (84.9%) at 18 months and 829.2 kg compared with 712.6 kg for German Holsteins (85.9%) at 24 months of age The dressing percentage for German Simmental was 3.7 and 3.6% higher than that of German Holstein at 18 and 24 months respectively. German Simmental had advantages in meat gain, especially for weight and percentage of meat cuts and muscle meat percentage with lower intermuscular fat. The differences for meat and muscle meat percentage were 0.9-3.7% and 2.8-6.2% respectively. They were largely age dependent. In intermuscular fat the percentage for German Simmental is 1.8-3.0% lower than for German Holstein. The differences for carcass composition traits are lower than expected. It is concluded that selection of German Holstein for improved milk performance traits had deleterious effects on the fattening and meat properties.
