| Abstrakt | Our study aimed to identify the overall and cluster-specific characteristics of Czech beef cattle breeding systems. We used data from an online survey to ascertain farmers‘ preferences in breeding objectives. Considering various evaluation criteria and clus-tering approaches in 41 farms, three beef systems were defined according to herd size, management, marketing, breeding strategies and structures, and farmer age. Breeding values and performance were jointly used as the primary information in all three sys-tems. Cow temperament and calf viability, maternal fertility and longevity, and ani-mal health were found to be the most important traits. Cluster 1 represents pure-breeding farms that specialize in producing breeding animals. Farms in clusters 2 and 3 combined pure- and crossbreeding strategies with production, which was par-tially (cluster 2) and fully (cluster 3) diversified for all beef categories. Farms also pri-oritized calving performance and calf growth (clusters 1 and 2) and exterior traits (cluster 3). Production type scores significantly (p < 0.05) differed in clusters 3 (4.12) and 2 (3.25). The proportion of production, functional, and exterior trait categories was 12:37:51, with low variability among clusters (+-1 to 2 percentage points). The in-ter-cluster comparison showed that specific characteristics were compatible with cer-tain breeding goal trait preferences. |
