Summary

The objective of this study was to compare the breeds German Holstein (HF,
30 animals) and German Red Pied (dual purpose) (RBT, 33 animals) in terms of milk
yield, BCS and weight and the fat-protein ratio in milk during the first five weeks of
lactation. HF had a higher mean daily yield than RBT (28.7 vs. 24.3 kg ECM). The
mean dry matter intake of the mixed ration was 1 kg/d higher for the HF than the RBT,
but this additional energy intake could not compensate fully the higher energy output
via milk. Therefore the HF had a more negative energy balance than the RBT, but the
expected higher loss of BCS or weight was not observed. Both breeds lost a mean of
0.2 BCS-points. A possible reason for this might be breed differences in the distribution
of body fat reserves. But a higher mean fat-protein ratio in the HF (1.45 vs. 1.27)
and a value above the reference value, indicating a higher risk of ketosis, for the HF
cows were signs of higher metabolic stress. Nonetheless the number of diseased
animals was similar in both breeds. A possible higher incidence of subclinical metabolic
or udder diseases in the HF is studied currently.
