| Abstract | The methodology for calculation of selection index for beef cattle in the Czech Republic was designed. Three selection indexes were constructed for bulls of beef cattle: IM for terminal crossing (in dairy herds), IZ for the selection of foundation siresfor beef herd and IS for the selection of bulls for beef herd. The sources of information were breeding values routinely calculated in performance testing – 10 breeding values for direct and maternal effects for easy calving and growth, breeding value for daily gain of bulls at performance-testing stations and 10 breeding values for the type traits of young animals. |
