Abstract
Data of about 12000 crossbred daughters are included in the investigat ions. A high correspondence was given between expected and by mean of simulated selection (splitted groups of offsprings from 582 sires) rea lised selection gains. The direct selection for feed efficiency is mor e efficient than the indirect methods, however the superiority is lowe r compared with other investigations.
