Genetic and phenotypic trends for weights of major beef and dual-purpose cattle breeds in Slovak Republic

Genetic evaluation of beef cattle in Slovakia started in first years of this century. After the first decade of running the routine evaluations it is important to review the progress made and to discuss the further development. The aim of this paper was to compile and deliver genetic and phenotypic trends in order to review importance of evaluated traits with respect to four major beef (Charolais, Limousine) and dual-purpose breeds (Slovak Pinzgau cattle, Slovak Spotted cattle). The study showed different progress made across the breeds. Higher genetic progress was observed in Charolais purebreds compared to Limousine counterparts. Moreover, almost similar progress to that in Charolais was observed in dual-purpose Slovak Pinzgau cattle. On the other hand no progress was observed in Slovak Spotted purebreds. Results also showed higher progress in bulls compared to cows. Phenotypic trends showed reserves for improvement in Charolais and closing to breed standards in Limousine. In dualpurpose breeds improvement was shown only in Slovak Pinzgau, while no improvement or decrease in actual weights was shown in Slovak Spotted purebreds.
