The aim of the paper concerns the selection of zoometrical measurements X to evaluate the slaughter value of fat stocks Y. The 14 characters of X and the 79 characters of Y have been analysed. The structure of both the X and Y characters have been examined by using canonical analysis and multiple regression. The date analysis shows, that slaughter value can be described by 12 characters and this set of characters can be evaluated by using 6 zoometrical measurements.
