Sažetak
The influence of cattle breed on production results was investigated on 40 selected dairy farms in the Vukovar-Srijem county. Applying Canonical Discrimination Analysis and a calculating natural and economic parameters of production it was established that the genetic potential of cows for milk production on the investigated family farms was not utilized sufficiently. Furthermore, there is no distinctly significant difference between Holstein Friesian and Simmental cows in the main parameters of production efficiency and in production, thus on the achieved level of production intensity introduction of Holstein-Friesian cows is economically unjustified. The principle that with the increase of herd the yield of milk increases too, but fat and protein are approximately the same was also confirmed in our investigations. The results obtained show that growth of production is not followed by qualitative improvement in production organization.
