Sažetak
Cows of Simmental breed and Crossbreeds between the Simmental and Red Holstein- Friesian breed were used in these experiments.
The Crossbreeds have achieved higher milk production, quantity of butter-fat, while the differences in butter-fat contents have not been found. The differences of the age at the first calving, gestation period and the service period have not been found, either.
The Crossbreeds had larger withers height and chest depth unlike the chest and flunk width where such differences have not been found'
These animals achieved a better under mark, but not a better mark for the type and shape.
