A bioeconomic model simulating a beef integrated enterprise has been developed to derive economic values for beef production traits. Traits considered were postweaning average daily gain (ADG), live fleshiness scores (FLESH) that reflect slaughter value of the fattened animals, calving ease (CE) and calving interval (FERT). It was shown that economic values in Euro were 0.13 per g/day for ADG, 48.02 per point for FLESH, 2.61 per 1% increase in the liability scale for CE and -1.99 per day for FERT. Sensitivity of economic values was tested. The economic value of ADG increased over 4 times when growth was reduced of 10%. FLESH was little affected by changes in muscular development. Economic value of CE was higher when dystocia increased, while FERT importance reduced when female fertility declined. Output or input limitation affected the economic values of ADG, CE and FERT.
