Data of crossbreeding for beef production was analyzed for Slovenia. Analysis was made on data for young bulls aged 12-24 months which were slaughtered in Slovenian abattoirs in the period from 2007-2009. A comparison was made for crossings of main cow breeds (CB-Holstein, RJ-Brown, LS-Simmental) with main meat breeds (Limousin-LIM, Charolais-CHA, Belgian blue-BBP) used in Slovenia. The improvement of carcass value when crossing with meat breeds was proportional to the dairy type of the cow, it was the most important in the case of CB, a little lesser in the case of RJ, whereas much smaller effect was observed in the case of LS breed. Crossing with CHA was the most important for growth performance (higher carcass weight and net daily gain), whereas crossing with BBP was the most efficient for improving conformation and decreasing fatness. Practically no improvement (in terms of EUROP classification) was observed in the case of LS×LIM crossing. In the context of the price system actually in place in Slovenia, the overall realization at the slaughter line implies, that only crossing with CHA breed has some advantage compared to the bulls of LS breed, however this crossing is little used in Slovenia.
